Just to close the loop ifor everyone else on the IRC discussion Brian and I had - removing the break statement is likely to cause problems with xfs_convert_page(). What xfs_convert_page() assumes is that xfs_check_page_type() will return true iff the first iand subsequent buffers on the page match the given type and can be written back. Skipping over buffers that have unknown contents is incorrect behaviour - if the first buffer on the page is unmapped, then it should break and return false. However, xfs_aops_discard_page() requires it to check all buffers on the page for delalloc state so that we can punch them correctly, and so breaking out at the first unwriteable buffer is a bug. Hence to fix this, we need to change the way xfs_convert_page() works. It needs to stop processing buffesr in it's main loop whenever "done" gets set so that it stops at the same point that xfs_check_page_type() stops checking the buffers on the page. Once that is done, then we can modify xfs_check_page_type() to return true when it finds the first buffer of a given type on the page or false if it finds an unmapped buffer and we are looking for IO_DELALLOC.... And it needs a decent set of comments, too :) Cheers, Dave. -- Dave Chinner david@fromorbit.com From david@fromorbit.com Sun Mar 2 22:43:56 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id E6F2C29DF7 for ; Sun, 2 Mar 2014 22:43:55 -0600 (CST) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay2.corp.sgi.com (Postfix) with ESMTP id BA765304032 for ; Sun, 2 Mar 2014 20:43:52 -0800 (PST) X-ASG-Debug-ID: 1393821829-04cbb066e71b8b00001-NocioJ Received: from ipmail06.adl6.internode.on.net (ipmail06.adl6.internode.on.net [150.101.137.145]) by cuda.sgi.com with ESMTP id ODMBRdUlngXuCyCY for ; Sun, 02 Mar 2014 20:43:50 -0800 (PST) X-Barracuda-Envelope-From: david@fromorbit.com X-Barracuda-Apparent-Source-IP: 150.101.137.145 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: AtydAJkHFFN5LJYePGdsb2JhbABagwY7gwiFDKAjBJMQhnQXAwEBAQEfGQ0ogmYcOyQ0BSUDBy2HeJw9r3cWjWx0ghgPgXsEmDuVbSiBLQ Received: from ppp121-44-150-30.lns20.syd7.internode.on.net (HELO dastard) ([121.44.150.30]) by ipmail06.adl6.internode.on.net with ESMTP; 03 Mar 2014 15:13:49 +1030 Received: from dave by dastard with local (Exim 4.80) (envelope-from ) id 1WKKjD-0002UA-BC for xfs@oss.sgi.com; Mon, 03 Mar 2014 15:43:47 +1100 Date: Mon, 3 Mar 2014 15:43:47 +1100 From: Dave Chinner To: xfs@oss.sgi.com Subject: [ANNOUNCE] xfsprogs: master branch updated to 48733b2 Message-ID: <20140303044347.GH13647@dastard> X-ASG-Orig-Subj: [ANNOUNCE] xfsprogs: master branch updated to 48733b2 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) X-Barracuda-Connect: ipmail06.adl6.internode.on.net[150.101.137.145] X-Barracuda-Start-Time: 1393821830 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.145683 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- Hi folks, The xfsprogs repository at git://oss.sgi.com/xfs/cmds/xfsprogs has just been updated.

The first patch fixes this regression. The second patch fixes a long standing issues with vmapped RAM potentially causing deadlocks due to GFP_KERNEL allocations being done for page tables inside GFP_NOFS contexts. This will fix many of the lockdep reports about it, but won't get rid of them all. It will, however, guarantee that we won't deadlock due to the problem which is a big step up. Cheers, Dave.

We can also see these same problems from anywhere where we use vmalloc for a large buffer (e.g. attribute code) inside a transaction context.

To do that, use the method that DM and other IO context code uses to avoid this problem: there is a process flag to tell memory reclaim not to do IO that we can set appropriately. That prevents GFP_KERNEL context reclaim being done from deep inside the vmalloc code in places we can't directly pass a GFP_NOFS context to. That interface has a pair of wrapper functions: memalloc_noio_save() and memalloc_noio_restore(). Adding them around vm_map_ram and the vzalloc call in kmem_alloc_large() will prevent deadlocks and most lockdep reports for this issue. Also, convert the vzalloc() call in kmem_alloc_large() to use __vmalloc() so that we can pass the correct gfp context to the data page allocation routine inside __vmalloc() so that it is clear that GFP_NOFS context is important to this vmalloc call.

This fixes a xfs/005 regression. Can you say a little more about the philosophy here? xfs/005 regresses because it expects "structure needs cleaning" So if we instead return our (icky) CRC error code, we get something else. But it is truly a different root cause. So the goal is to NEVER leak EFSBADCRC to userspace? Maybe a comment above that error definition would help document that. And I'm bit worried that we'll leak more in the future if things changed, or if things got missed here. Everything you have here looks fine, but it's not obvious that every path has been caught; it seems a bit random. I know we _just_ merged my "differentiator" patches, but I wonder if it would be better to add XFS_BSTATE_BADCRC to b_state or some other field, and go back to always assigning EFSCORRUPTED. What do you think? When I wrote those I wasn't thinking about keeping it all internal to the filesystem. -Eric > Signed-off-by: Dave Chinner > --- > fs/xfs/xfs_mount.c | 3 +++ > fs/xfs/xfs_symlink.c | 4 ++++ > fs/xfs/xfs_trans_buf.c | 11 +++++++++++ > 3 files changed, 18 insertions(+) > > diff --git a/fs/xfs/xfs_mount.c b/fs/xfs/xfs_mount.c > index f96c056..993cb19 100644 > --- a/fs/xfs/xfs_mount.c > +++ b/fs/xfs/xfs_mount.c > @@ -314,6 +314,9 @@ reread: > error = bp->b_error;

This fixes a xfs/005 regression. > > Signed-off-by: Dave Chinner > --- This change looks Ok to me, but when I start looking through the users of bp->b_error, I see examples like xfs_dir3_data_read() being called in xfs_dir2_leaf_addname() where it looks like an error could bubble all the way up to xfs_vn_mknod() and its callers. If the intent is to use EFSBADCRC as an internal-only error to differentiate corruption from crc failure, why not push this more closely to the boundaries that we have already defined? For example, we already convert positive errnos to negative at the internal/external boundaries. Could we convert those to use some kind of XFS_USERSPACE_ERROR(error) macro/helper that converts errors appropriately? Another thought could be to reconsider whether we still need some of these extra warnings, as in the xfs_mount.c hunk below, now that we have the generic xfs_verifier_error() messaging. E.g., if we could remove those, perhaps we could snub out EFSBADCRC in or around the verifier after it makes a distinction.

Array has been multiply rebuilt due to drive insertions. XFS filesystem damaged and trying to salvage what I can, and I want to make sure I have no option other than "xfs_repair -L". Details follow. # uname -a Linux rccstor7.local 2.6.32-431.5.1.el6.x86_64 #1 SMP Wed Feb 12 00:41:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux xfs_repair version 3.1.1. The box has one 4-core Opteron CPU and 8 GB of RAM. I have a 32TB HW RAID60 volume (Areca 1680 HW RAID) made of two RAID6 raid sets. This volume is a PV in Linux LVM, with a single LV defined in it. The LV had an XFS filesystem created on it (no external log). I can't do xfs_info on it because I can't mount the filesystem. I had multiple drive removals and insertions (due to timeout error with non-TLER drives in the RAID array, an unfortunate setup I inherited), which triggered multiple HW RAID rebuilds. This caused the RAID volume to end up defined twice in the controller, with each of the two constituent RAID sets being defined twice. At Areca's direction, I did a "raid set rescue" in the Areca controller. That succeeded in reducing the number of volumes from two to one, and the RAID volume is now "normal" in the RAID controller instead of "failed". The logical volume is visible to the OS now, unlike when the RAID status was "failed". # lvdisplay --- Logical volume --- LV Path /dev/vg0/lv0 LV Name lv0 VG Name vg0 LV UUID YMlFWe-PTGe-5kHx-V3uo-31Vp-grXR-9ZBt3R LV Write Access read/write LV Creation host, time , LV Status available # open 0 LV Size 32.74 TiB Current LE 8582595 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2 That's good, but now I think the XFS filesystem is in bad shape. # grep /media/shares /etc/fstab UUID="9cba4e90-1d8f-4a98-8701-df10a28556da" /media/shares xfs pquota 0 0 That UUID entry in /dev/disk/by-uuid is a link to /dev/dm-2.

The log failure is probably just the first error xfs encounters; I imagine that after you zap the log, you'll find that everything else is in equally bad shape. You could _try_ an # xfs_metadump -o /dev/whatever fs.metadump # xfs_mdrestore fs.metadump fs.img and then try your various metadata salvage techniques on fs.img (recreating as necessary with another xfs_mdrestore after failure) as practice runs, but I'm guessing that xfs_metadump will fail in equally spectacular ways. Unless you can get your storage somehow reassembled properly, I doubt that there's much xfs tools can do to help you. -Eric > I'm just trying to salvage whatever I can from this FS.

At the moment, none of the code handles it correctly, and the leak to userspace is just a symptom that tells us we got somethign wrong.

It's buffer reads that matter, and I checked all the calls to xfs_buf_read, xfs_buf_read_map, xfs_trans_read_buf and xfs_trans_read_buf. There aren't any other read interfaces that use verifiers, and so nothing else can return EFSBADCRC. For the log recovery cases, the buffer reads don' use verifiers, and those that do won't return EFSBADCRC (e.g. inode buffers). > I know we _just_ merged my "differentiator" patches, but I wonder if > it would be better to add XFS_BSTATE_BADCRC to b_state or some other > field, and go back to always assigning EFSCORRUPTED. What do you think? It's just the first layer of adding differentiating support. We've just put the mechanism in place to do the differentiation because we need it for *userspace functionality* before we need it for in-kernel functionality. We put it in the kernel because it has value to us developers to indicate what type of corruption error was detected in the dmesg output. We can't however, do everything at once, so for the moment the kernel code needs to translate it back to something the higher layers understand and treat correctly. > When I wrote those I wasn't thinking about keeping it all internal > to the filesystem.

Sure, but: xfs_dir3_data_read xfs_da_read_buf xfs_trans_read_buf_map Which means the patch prevents the EFSBADCRC leaking back out through that path because it converts it in xfs_trans_read_buf_map. > If the intent is to use EFSBADCRC as an internal-only error to > differentiate corruption from crc failure, why not push this more > closely to the boundaries that we have already defined?

That doesn't solve the problem needing an error conversion layer in the first place. The long term goal is to remove the error conversions in XFS by converting the core code to the same error passing conventions as the rest of the kernel code. We manage to screw the negation up fairly regularly because it is convoluted and we cal into generic code that returns negative errors from the core that returns positive errors in lots of places. The conversion surface is just too large to manage sanely. > Another thought could be to reconsider whether we still need some of > these extra warnings, as in the xfs_mount.c hunk below, now that we have > the generic xfs_verifier_error() messaging. E.g., if we could remove > those, perhaps we could snub out EFSBADCRC in or around the verifier > after it makes a distinction. Redundant errors aren't s significant problem. It's the lack of meaningful error messages that are much more of an issue. We get more meaningful error messages as a result of the EFSBADCRC changes that have been made, but for the moment that error simply means EFSCORRUPTED to the higher layers. Hence the translation back to EFSCORRUPTED at the (low) layers where the error no longer has a distinct meaning. As we add more functionality, EFSBADCRC will become more meaningful and so get propagated higher into the kernel code. But for now, it should remain an error that doesn't escape the lower layers...

Hmmm - yet another horror story from someone using an Areca HW RAID controller.

Pray? Basically, then primary metadata in the filesystem that tracks allocated space and inodes looks to be badly corrupted. If the metadata is corrupted like this from the rebuild, then the rest of the block device is likely to be busted up just as badly. So you might be able to recover some of the filesysetm structure with XFS repair, but all your data is going to be just as corrupted. I'd be using metadump like Eric suggested to create a test image to see what filesystem structure you'll end up with after running repair. But with the corrupt AG btrees, there's a good chance even metadump won't be able to run successfully on the filesystem.

Rather, if the only thing preventing the consolidation of the EFSBADCRC trap to a single hunk are redundant errors, then it wouldn't be a problem to remove those errors and push the EFSBADCRC trap into the generic code for the purpose of clarity.

I'm not sure there's any real benefit to adding infrastructure when doing the conversion. It's a lot of little changes involving pushing the conversion down from the top layers, combined with converting interfaces (e.g. bmapi) as they get exposed. Some functions will be able to lose variables as the return becomes a tri-state value (e.g. the btree functions for looking up records); others will be able to use IS_ERR() for pointer returns, and so on. This will have a flow on effect on the code in the callers, and so it really comes down to spending the time to peel back each layer carefully. It's a lot of work, hence the "long term goal" aspect of it. We've been talking about doing this cleanup for several years now, but it hasn't yet been done because it's going to take hundreds of patches to do... ;) > > > Another thought could be to reconsider whether we still need some of > > > these extra warnings, as in the xfs_mount.c hunk below, now that we have > > > the generic xfs_verifier_error() messaging.

I don't see much point in trying to have a single trap for EFSBADCRC because the moment we want to handle one of those cases specially we are going to have to - as a first step - remove the single trap and push it outwards to all the places that need it like this patch does....

There are known prior bugs which leave junk at the end of the V4 superblock; we don't need to actually fail the verification in this case if other checks pan out ok. So if this is a secondary superblock, and the primary superblock doesn't indicate that this is a V5 filesystem, don't treat this as an actual checksum failure. We should probably check the garbage condition as we do in xfs_repair, and possibly warn about it or self-heal, but that's a different scope of work.

If it's out of bounds, we can go off the rails in i.e. xfs_inode_buf_verify(), which uses sb_inopblock as a loop limit when stepping through a metadata buffer. The problem can be demonstrated easily by corrupting sb_inopblock with xfs_db and trying to mount the result: # mkfs.xfs -dfile,name=fsfile,size=1g # xfs_db -x fsfile xfs_db> sb 0 xfs_db> write inopblock 512 inopblock = 512 xfs_db> quit # mount -o loop fsfile mnt and we blow up in xfs_inode_buf_verify(). With this patch, we get a (very noisy) corruption error, and fail the mount as we should.

It brings across all the relevant pathes form the kernel code and shoe-horns them into the libxfs codebase. There are two extra patches on the end of the series - one to make xfs_db use EFSBADCRC for it's CRC validity indication, and the other to make xfs_repair detect and handle primary superblock CRC failures and recalculation when the primary superblock is rebuilt and rewritten. This is the first step in bring full awareness of CRC errors into xfs_repair. More patches will follow as I make more repair code aware that EFSBADCRC means that the object that was just read needs repair. Cheers, Dave.

This may or may not match the filesystem sector size in sb_sectsize, so we can't i.e. do a CRC check on it; it might be too short. In fact, mounting a filesystem with sb_sectsize larger than the device sector size will cause a mount failure if CRCs are enabled, because we are checksumming a length which exceeds the buffer passed to it. So always read twice; the first time we read with NULL buffer ops to skip verification; then set the proper read length, hook up the proper verifier, and give it another go. Once we are sure that we've got the right buffer length, we can also use bp->b_length in the xfs_sb_read_verify, rather than the less-trusted on-disk sectorsize for secondary superblocks. Before this we ran the risk of passing junk to the crc32c routines, which didn't always handle extreme values.

Also, *any* errors in xfs_mount_validate_sb which are not corruption per se; things like too-big-blocksize, bad version, bad magic, v1 dirs, rw-incompat etc - things which do not return EFSCORRUPTED - will still do the whole XFS_CORRUPTION_ERROR spew when xfs_sb_read_verify sees any error at all. And it suggests to the user that they should run xfs_repair, even if the root cause of the mount failure is a simple incompatibility. I'll submit that the probably-not-corrupted errors don't warrant this much noise, so this patch removes the warning for anything other than EFSCORRUPTED returns, and replaces the lower-level XFS_CORRUPTION_ERROR with an xfs_notice().

It does not verify that the CRC of the superblock that is found is correct, nor does it recalculate the CRC of the superblock it rewrites. This happens because phase1 does not use the libxfs buffer cache - it just uses pread/pwrite on a memory buffer, and works directly from that buffer. Hence we need to add CRC verification to verify_sb(), and CRC recalculation to write_primary_sb() so that it works correctly. This also enables us to use get_sb() as the method of fetching the superblock from disk after phase 1 without needing to use the libxfs buffer cache and guessing at the sector size. This prevents a verifier error because it attempts to CRC a superblock buffer that is much longer than the usual sector sizes.

This sets the appropriate error number on bp->b_error, and then calls xfs_verifier_error() if something went wrong. That function will issue the appropriate message to the user. Also, fix the silly bug in xfs_buf_ioerror() that this patch exposes.

No, O_TMPFILE doesn't take an actual file name but a "virtual" parent directory. It's a reall creative abuse of the open ABI.. > Also, I don't see the file being linked into the namespace, so the > comment is probably wrong. Also, please add a comment as to > why the freeze/thaw is necessary. Yes, we don't want to link it so that we have it on the unlinke dinode list. The freeze/thaw is to make sure the log has been cleaned, I'll add a comment explaining it. > There it is, but is moving it to lost+found the right thing to do, > given that it was on the unlinked list and should have had a zero > link count? i.e. aren't we supposed to free unlinked inodes with a > zero link count, not recover them to lost+found? > Yeah, that seems like the wrong behaviour to have for an anonymous > O_TMPFILE file - it's making it visible because we moved it to > lost+found in phase 6.... Good question. I thought about this a little and decided that it wasn't worth special casing O_TMPFILE inodes in repair, but thinking about it a bit more this also happens for normal unlinked but open files. I can look into this if you want, and would create another test for that case. > > Also, I don't see any icount mismatch, so the comment above in the > test is probably wrong. We do have an icount mismatch, but _filter_repair filters it away.

This solved a transaction overrun when logging the inode size. Recently, however, we've seen a number of these same overruns on kernels with the above fix in it. All of them have been by 4 bytes, so we must still not be accounting for something correctly. Through inspection it turns out the above commit didn't take into account everything it should have. That is, it only accounts for a single log op_hdr structure, when it can actually require up to four op_hdrs - one for each region (log iovec) that is formatted. These regions are the inode log format header, the inode core, and the two forks that can be held in the literal area of the inode. This means we are not accounting for 36 bytes of log space that the transaction can use, and hence when we get inodes in certain formats with particular fragmentation patterns we can overrun the transaction. Fix this by adding the correct accounting for log op_headers in the transaction.

The cause of this is failure to clean up the delalloc range on a page where the first buffer does not match one of the expected states of xfs_check_page_type(). If a buffer is not unwritten, delayed or dirty&mapped, xfs_check_page_type() stops and immediately returns 0. The stress test of generic/224 creates a scenario where the first several buffers of a page with delayed buffers are mapped & uptodate and some subsequent buffer is delayed. If the ->writepage() happens to fail for this page, xfs_aops_discard_page() incorrectly skips the entire page. This then causes later failures either when direct IO maps the range and finds the stale delayed buffer, or we evict the inode and find that the inode still has a delayed block reservation accounted to it. We can easily fix this xfs_aops_discard_page() failure by making xfs_check_page_type() check all buffers, but this breaks xfs_convert_page() more than it is already broken. Indeed, xfs_convert_page() wants xfs_check_page_type() to tell it if the first buffers on the pages are of a type that can be aggregated into the contiguous IO that is already being built. xfs_convert_page() should not be writing random buffers out of a page, but the current behaviour will cause it to do so if there are buffers that don't match the current specification on the page. Hence for xfs_convert_page() we need to: a) return "not ok" if the first buffer on the page does not match the specification provided to we don't write anything; and b) abort it's buffer-add-to-io loop the moment we come across a buffer that does not match the specification. Hence we need to fix both xfs_check_page_type() and xfs_convert_page() to work correctly with pages that have mixed buffer types, whilst allowing xfs_aops_discard_page() to scan all buffers on the page for a type match.

The second is a fix for a transaction overrun problem that has been showing up on RHEL7 kernels quite frequently of late. It has been reproduced on upstream kernels as well, and the patch should address the oversight made in previous fixes to the inode reservation size calculation. Cheers, Dave.

This fixes a xfs/005 regression. > > Signed-off-by: Dave Chinner > --- Looking through again, I don't see any obvious cases where EFSBADCRC could slip through. The verifier users mostly call xfs_trans_read_buf_map(). The readahead case looks like it should be handled by the xfs_buf_iowait() checks therein. The one case I came across that looked suspicious is the readahead/read cycle for inode log recovery in xlog_recover_commit_trans(). This calls into xfs_buf_read() and ultimately uses bp->b_error directly in xlog_recover_inode_pass2(). That said, I don't see any crc checking in these verifiers and thus they don't source EFSBADCRC. Looks good to me...

This is similar to the test xfs/290 however this one is generic and we're testing different block sizes as well - namely 1k, 2k, 4k and 64k. Note that we're not creating file systems with given block size buy rather test all 4 options.

Yeah, that does seem better! Thanks for spotting that. The difference when calling inode_item_unlock is a bit more zeroing-out: ip->i_transp = NULL; iip->ili_flags = 0; I'm not sure of the implications of that offhand, TBH.

I'm still throwing a workload at it, but this has survived a few hours of a reproducer that consistently caused the overrun in 5-10 seconds. Thanks for catching this.

After the first lockup, I booted into single user mode, mounted the filesystem readonly, and then ran xfs_repair -d. When I rebooted again, I initiated a large copy to a USB drive (formated EXT3) and continued editing source files and compiling. After a couple minutes, my laptop started locking up and after 2 minutes, the following showed up in the kernel.

Do you think it's possible to get here on the first > buffer of the page, without having reset 'uptodate,' and potentially > incorrectly set the page uptodate? Good question :) I don't think this can happen because if the first buffer on the page can't be written, xfs_check_page_type() will return false and we won't get to the loop. By definition, buffer_unwritten() implies buffer_uptodate(), as does buffer_delay() and buffer_dirty(). Hence any of the types that will return acceptible will have the first buffer uptodate. As for the other breaks in the loop - the initial imap_valid check ensures we have a map that covers the entire region of the page that needs writing, and we know that offset < end_offset for the first buffer on the page. Hence none of the loop breaks will trigger on the first buffer, and so the above code should not trigger.

So, this is a block device problem error handling problem caused by device unplug getting stuck because it's decided to ask the filesystem to complete operations that can't be completed until the device error handling progress far enough to error out the IOs that the filesystem is waiting for completion on.

Strip out all the version 1-3 support, sanitise the good version checking to reflect the supported versions, update all the feature supported functions and clean up all the support bit definitions to reflect the fact that we no longer care about Irix bootloader flag regions for v4 feature bits.

The journal only contains in flight transactional metadata for recovery purposes after a system crash or power loss, to prevent filesystem, i.e. metadata, corruption. The journal does not contain file data. During normal operation, once the metadata has been written into an allocation group the transactional entry in the journal is removed. Thus, recovering deleted files has nothing to do with the journal.

They did. logv2 came from irix, and the borgbit did too. Hence we can be guaranteed that if any of these bits exist on irix, then dirv2 fields are present in the superblock, too. > I'd vote to kill XFS_SB_NEEDED_FEATURES and just check the dirv2 bit > explicitly. Ok. The only real reason I did this was in case there's a single bit error that clears the dirv2 bit, but it still contains other bits that indicate that the superblock is recent enough that we understand it's contents and what should bein the fs. e.g. for db/repair purposes - if the dir2 bit is not set, but any of the above bits are set and the m_dirblklog is and it is sane, we can assume that we've lost the feature bit and repair it. > > +/* > > + * Supported feature bit list is just all bits in the versionnum field because > > + * we've used them all up and understand them all. > > + */ > > +#define XFS_SB_VERSION_OKBITS \ > > + (XFS_SB_VERSION_NUMBITS | \ > > + XFS_SB_VERSION_ALLFBITS) > > > > > +#define XFS_SB_VERSION2_OKBITS \ > > (XFS_SB_VERSION2_LAZYSBCOUNTBIT | \ > > XFS_SB_VERSION2_ATTR2BIT | \ > > XFS_SB_VERSION2_PROJID32BIT | \ > > XFS_SB_VERSION2_FTYPE) > > > +/* > > + * The first XFS version we support is filesytsems with V2 directories. > > + */ > > is a v4 superblock with v2 directories? *nod* > > Also filesystem is mis-spelled. > > > static inline int xfs_sb_good_version(xfs_sb_t *sbp) > > { > > + /* We only support v4 and v5 */ > > + if (XFS_SB_VERSION_NUM(sbp) < XFS_SB_VERSION_4 || > > + XFS_SB_VERSION_NUM(sbp) > XFS_SB_VERSION_5) > > + return 0; > > + > > + /* > > + * Version 5 feature checks are done separately. > > + */ > > + if (XFS_SB_VERSION_NUM(sbp) == XFS_SB_VERSION_5) > > return 1; > > How about doing this a little different? > > static inline int xfs_sb_good_version(struct xfs_sb *sbp) > { > if (XFS_SB_VERSION_NUM(sbp) == XFS_SB_VERSION_5) > return 1; > if (XFS_SB_VERSION_NUM(sbp) == XFS_SB_VERSION_4) > return xfs_sb_good_v4_features(sbp); > return 0; > } > > then move the bulk of the function into xfs_sb_good_v4_features?

Should I just drop it out of the supported feature matrix and drop all other checks on that field? That way we can then remove all the the crap that tries to validate it from xfs_repair, too. I have no idea what is actually valid for this field, so I think we should simply drop support of it from everything. > > static inline int xfs_sb_version_hasattr(xfs_sb_t *sbp) > > { > > + return !!(sbp->sb_versionnum & XFS_SB_VERSION_ATTRBIT); > > } > > Should this become a bool?

Seems unrelated to the other changes. I noticed that these feature bits weren't updating the bad_features2 field and keeping it consistent with features2, which they should. I'll separate this out into another patch.

There is some documentation about some of the logging concepts and design. eg: http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs-documentation.git;a=blob;f=design/xfs-delayed-logging-design.asciidoc But the only way to learn about the actual structure of the log is to read the code and use xfs_logprint to study the contents of the log.

To Yongmin, For your information only. I'm trying to understand XFS journal via the following steps: 1) Download Linux-2.6.34 source, read the journal code. Understand the original design as there is no delayed-logging support at that time. FYI, two obsoleted documents could be found at, http://oss.sgi.com/projects/xfs/design_docs/xfsdocs93_pdf/log_mgr-overview.pdf http://oss.sgi.com/projects/xfs/design_docs/xfsdocs93_pdf/log_mgr.pdf 2) Download Linux-2.6.35 source, read the journal code and delayed-logging-design doc as per Dave's suggestion because we have this big change in this version. 3) Play with xfs_logprint with the XFS mainline source and read all those threads in XFS mailing list which are related to journals in the past several years.... 4) Nothing, just have fun. :) Thanks, -Jeff From david@fromorbit.com Thu Mar 6 22:19:38 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id E57A97F50 for ; Thu, 6 Mar 2014 22:19:38 -0600 (CST) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay2.corp.sgi.com (Postfix) with ESMTP id B860830407F for ; Thu, 6 Mar 2014 20:19:35 -0800 (PST) X-ASG-Debug-ID: 1394165972-04bdf05dab33de40001-NocioJ Received: from ipmail07.adl2.internode.on.net (ipmail07.adl2.internode.on.net [150.101.137.131]) by cuda.sgi.com with ESMTP id v6uZx4Zu26Yv2HGR for ; Thu, 06 Mar 2014 20:19:33 -0800 (PST) X-Barracuda-Envelope-From: david@fromorbit.com X-Barracuda-Apparent-Source-IP: 150.101.137.131 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: As4oAJNHGVN5LJYe/2dsb2JhbABagwY7qQ8EkxCFXIEYF3SBWDIBGgEBAQIBATocFwwFCwgDEgYJJQ8FJQMNFBOHcQcOz2sWjEmBfAeEOASYQDeRdYNBKA Received: from ppp121-44-150-30.lns20.syd7.internode.on.net (HELO dastard) ([121.44.150.30]) by ipmail07.adl2.internode.on.net with ESMTP; 07 Mar 2014 14:49:31 +1030 Received: from dave by dastard with local (Exim 4.80) (envelope-from ) id 1WLmFh-000867-Qo; Fri, 07 Mar 2014 15:19:17 +1100 Date: Fri, 7 Mar 2014 15:19:17 +1100 From: Dave Chinner To: Jeff Liu Cc: Yongmin , xfs@oss.sgi.com Subject: Re: Hello, I have a question about XFS File System Message-ID: <20140307041917.GP6851@dastard> X-ASG-Orig-Subj: Re: Hello, I have a question about XFS File System References: <195DE8C60CE24A62A71911FDE0B0DC97@gmail.com> <20140306225947.GM6851@dastard> <53192DAA.1040305@oracle.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <53192DAA.1040305@oracle.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-Barracuda-Connect: ipmail07.adl2.internode.on.net[150.101.137.131] X-Barracuda-Start-Time: 1394165972 X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.3668 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Fri, Mar 07, 2014 at 10:23:38AM +0800, Jeff Liu wrote: > > > On 03/07 2014 06:59 AM, Dave Chinner wrote: > > On Thu, Mar 06, 2014 at 06:15:27PM +0900, Yongmin wrote: > >> > >> Hello. > >> > >> My name is Yongmin Park and I am a graduated student in Ajou University (Korea). > >> My research area is Digital Forensics. > >> And this time i tried to understand the structure of XFS file system, because XFS is one of the famous huge file system in these days. > >> > >> I already founded and read 'XFS Filesystem Structure 2nd Edition Revision 1' on the Internet, which was written by Silicon Graphics Inc in 2006 and it is really well written to understand. > >> > >> But the concentrated part of mine is "Deleted File Recovery", so the Journaling part is really important for me,, but regretfully there are no specific guide line about Journaling part... > >> Also next version(maybe the 3re Edition) is not exsist for more than a 5 years. > >> > >> So is there no guide line for journaling part in XFS? > >> How can i get them,, have I to buy them? or Is Analysing Source Cord only way to study? > > > > There is some documentation about some of the logging concepts and > > design. eg: > > > > http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs-documentation.git;a=blob;f=design/xfs-delayed-logging-design.asciidoc > > Not sure if someone else also think that XFS journal design is the stumbling-block > to get involved into the development...but I once heard of "I'm really confused by > the design of delayed logging, I have to give up after reading the document for about > 2 or 3 weeks..." from 2 Chinese developers in the past year, though nothing can help > someone out without taking infinite patience. Let me put it this way: it took me *5 years* of working deep in the XFS code to really understand how the XFS transaction and journalling subsystems are supposed to function. Delayed logging took me 3 failed design attempts over 3 years before I had learnt enough to come up with a design that worked. It's by far the most complex part of XFS - expecting to understand how it works by spending a couple of weeks reading the code is unrealistic. Fundamentally, understanding delayed logging means you have to first understand why relogging is necessary in the XFS journal. To understand why relogging is necessary, you first need to understand the transaction subsystem, the log space reservation subsystem, log recovery constraints, how tail pushing works, the physical log interface code, the on-disk log format, etc andhow they all interact. IOWs, delayed logging is the last thing in the journalling layer that anyone should try to understand because understanding it fully requires a high level of knoweldge about the XFS metadata and logging subsystem architecture and fundamental principles.... > > But the only way to learn about the actual structure of the log is to > > read the code and use xfs_logprint to study the contents of the log. > > To Yongmin, > > For your information only. > > I'm trying to understand XFS journal via the following steps: > > 1) Download Linux-2.6.34 source, read the journal code. > Understand the original design as there is no delayed-logging support at that time. Delayed logging changes neither the journal nor the transaction layer code or design. If you can't understand the fundamental principles behind those subsystems from the current code, then looking at the older code won't make it any clearer because it is exactly the same... > FYI, two obsoleted documents could be found at, > http://oss.sgi.com/projects/xfs/design_docs/xfsdocs93_pdf/log_mgr-overview.pdf > http://oss.sgi.com/projects/xfs/design_docs/xfsdocs93_pdf/log_mgr.pdf The first of those really doesn't contain much useful information. The second really only documents the physical log format. That might be useful as a first step, but it doesn't document any of the alogorithms that the log uses, and that is where all the complexity lies. Reading code will only get you so far - the only way to continue the learning process is by trying to modify the code and fixing what you break, along with asking questions about things you don't understand on the list so that people who do understand them can teach you things that aren't obvious from the code and aren't documented anywhere other than the code.

This solved a transaction overrun when logging the inode size. Recently, however, we've seen a number of these same overruns on kernels with the above fix in it. All of them have been by 4 bytes, so we must still not be accounting for something correctly. Through inspection it turns out the above commit didn't take into account everything it should have. That is, it only accounts for a single log op_hdr structure, when it can actually require up to four op_hdrs - one for each region (log iovec) that is formatted. These regions are the inode log format header, the inode core, and the two forks that can be held in the literal area of the inode. This means we are not accounting for 36 bytes of log space that the transaction can use, and hence when we get inodes in certain formats with particular fragmentation patterns we can overrun the transaction. Fix this by adding the correct accounting for log op_headers in the transaction.

The cause of this is failure to clean up the delalloc range on a page where the first buffer does not match one of the expected states of xfs_check_page_type(). If a buffer is not unwritten, delayed or dirty&mapped, xfs_check_page_type() stops and immediately returns 0. The stress test of generic/224 creates a scenario where the first several buffers of a page with delayed buffers are mapped & uptodate and some subsequent buffer is delayed. If the ->writepage() happens to fail for this page, xfs_aops_discard_page() incorrectly skips the entire page. This then causes later failures either when direct IO maps the range and finds the stale delayed buffer, or we evict the inode and find that the inode still has a delayed block reservation accounted to it. We can easily fix this xfs_aops_discard_page() failure by making xfs_check_page_type() check all buffers, but this breaks xfs_convert_page() more than it is already broken. Indeed, xfs_convert_page() wants xfs_check_page_type() to tell it if the first buffers on the pages are of a type that can be aggregated into the contiguous IO that is already being built. xfs_convert_page() should not be writing random buffers out of a page, but the current behaviour will cause it to do so if there are buffers that don't match the current specification on the page. Hence for xfs_convert_page() we need to: a) return "not ok" if the first buffer on the page does not match the specification provided to we don't write anything; and b) abort it's buffer-add-to-io loop the moment we come across a buffer that does not match the specification. Hence we need to fix both xfs_check_page_type() and xfs_convert_page() to work correctly with pages that have mixed buffer types, whilst allowing xfs_aops_discard_page() to scan all buffers on the page for a type match.

An example situation is: - process A attempts an inode allocation on AG 3, modifies the freelist, fails the allocation and ultimately moves on to AG 0 with the AG 3 AGF held - process B is doing a free space operation (i.e., truncate) and acquires the AG 0 AGF, waits on the AG 3 AGF - process A acquires the AG 0 AGI, waits on the AG 0 AGF (deadlock) The problem here is that process A acquired the AG 3 AGF while moving on to AG 0 (and releasing the AG 3 AGI with the AG 3 AGF held). xfs_dialloc() makes one pass through each of the AGs when attempting to allocate an inode chunk. The expectation is a clean transaction if a particular AG cannot satisfy the allocation request. xfs_ialloc_ag_alloc() is written to support this through use of the minalignslop allocation args field. When using the agi->agi_newino optimization, we attempt an exact bno allocation request based on the location of the previously allocated chunk. minalignslop is set to inform the allocator that we will require alignment on this chunk, and thus to not allow the request for this AG if the extra space is not available. Suppose that the AG in question has just enough space for this request, but not at the requested bno. xfs_alloc_fix_freelist() will proceed as normal as it determines the request should succeed, and thus it is allowed to modify the agf. xfs_alloc_ag_vextent() ultimately fails because the requested bno is not available. In response, the caller moves on to a NEAR_BNO allocation request for the same AG. The alignment is set, but the minalignslop field is never reset. This increases the overall requirement of the request from the first attempt. If this delta is the difference between allocation success and failure for the AG, xfs_alloc_fix_freelist() rejects this request outright the second time around and causes the allocation request to unnecessarily fail for this AG. To address this situation, reset the minalignslop field immediately after use and prevent it from leaking into subsequent requests.

However, the vmap interfaces do not provide any method of communicating this information to memory reclaim, and hence we get lockdep complaining about it regularly and occassionally see hangs that may be vmap related reclaim deadlocks. We can also see these same problems from anywhere where we use vmalloc for a large buffer (e.g. attribute code) inside a transaction context. A typical lockdep report shows up as a reclaim state warning like so: [14046.101458] ================================= [14046.102850] [ INFO: inconsistent lock state ] [14046.102850] 3.14.0-rc4+ #2 Not tainted [14046.102850] --------------------------------- [14046.102850] inconsistent {RECLAIM_FS-ON-W} -> {IN-RECLAIM_FS-W} usage.

To do that, use the method that DM and other IO context code uses to avoid this problem: there is a process flag to tell memory reclaim not to do IO that we can set appropriately. That prevents GFP_KERNEL context reclaim being done from deep inside the vmalloc code in places we can't directly pass a GFP_NOFS context to. That interface has a pair of wrapper functions: memalloc_noio_save() and memalloc_noio_restore(). Adding them around vm_map_ram and the vzalloc call in kmem_alloc_large() will prevent deadlocks and most lockdep reports for this issue. Also, convert the vzalloc() call in kmem_alloc_large() to use __vmalloc() so that we can pass the correct gfp context to the data page allocation routine inside __vmalloc() so that it is clear that GFP_NOFS context is important to this vmalloc call.

Ok, we don't reject filesystems that don't have the NLINK bit set. Older filesystems that have only v1 inodes won't have that bit set, and we didn't set NLINK by default in mkfs until late 2007. Hence we need to keep some form of NLINK support around. The alternative is to simply set the bit in the superblock if it is not set, and then just assume everywhere that it is set and we are using v2 inodes. That will get rid of the hasnlink/addnlink code needed to modify the superblock when the link count goes above MAX_NLINK_1, and will result in filesystems always converting v1 inodes to v2 inodes on writeback of dirty inodes. I don't see a problem with taking this approach, bt maybe I'm missing something? For the dirv2 function, it's only used for checking at mount time, so if that is handled bu xfs_sb_good_version() we no longer need it.... Your thoughts?

If the fstat command fails then the memory for the duplicated string is leaked. Fix this by moving the string duplication after the fstat call. This is ok because the fstat call does not use the duplicated string. Brian Foster noticed that the function also leaks a file descriptor in case the file cannot be fstated. Fixing that, too.

If a file has been deleted, no information about that is going to exist in the journal for more than a few seconds before the transaction is committed and the entry removed from the journal. > By using those information, Recovering delete file can be done. > > So the analysis of Journaling part is absolutely needed. I disagree. Again, the journal log is unrelated to "deleted file recovery" in a forensics scenario. I think Dave and Jeff both missed the fact that you're interested only in deleted file recovery, not in learning how the journal works for the sake of learning how the journal works. > ======================= > from Yongmin Park > ======================= > > > On 2014ë…„ 3ì›” 7ì¼ Friday at 오전 5:30, Stan Hoeppner wrote: > >> On 3/6/2014 3:15 AM, Yongmin wrote: >>> >>> Hello. >>> >>> My name is Yongmin Park and I am a graduated student in Ajou >>> University (Korea).

Well, we don't actually "remove" information from the log. We update pointers that indicate what the active region is, but we never physically "remove" anything from it.

Oh, no, I saw it and didn't think it was worth commenting on. I think it's a brain-dead concept trying to do undelete in the filesystem. "recoverable delete" was a problem solved 30 years ago - it's commonly known as a trash bin and you do it in userspace with a wrapper around unlink that calls rename(2) instead. And then "empty trashbin" is what does the unlink and permanently deletes the files. Besides, from a conceptual point of view after-the-fact filesystem based undelete is fundamentally flawed. i.e. the journal is a write-ahead logging journal and so can only be used to roll the filesystem state forwardi in time. Undelete requires having state and data in the journal that allows the filesystem to be rolled *backwards in time*. XFS simply does not record such information in the log and so parsing the log to "undelete files by transaction rollback" just doesn't work.

And then "empty > trashbin" is what does the unlink and permanently deletes the files. As a practicing forensicator, I can say "potentially recoverable files" is a heavily used concept. I don't know XFS on disk structure in detail, so I'll comment about HFS+ and NTFS. NTFS uses a simple linear on disk directory structure and inode (mft) structure. Forensic tools look at existing directory structures that have directory entries marked invalid and they also scan the unallocated space for directory remnants that were left behind from a delete operation. When either are found, they assume the data pointed at is "potentially recoverable". I think some tools also parse the NTFS journal, but it is a much less useful mechanism. Note that it is understood that the data pointed at by filesystem remnants may have been overwritten by new data, so it is unreliable. As a last resort, data carving tools equivalent to photorec are used. Photorec depends on the files not being fragmented and also fails to recover any filesystem metadata such as filenames, timestamps, etc. Macs use HFS+ which uses a btree structure for the directory structure. I'm not aware of any forensic tool that attempts to look for invalid directory remnants with HFS+. Instead they go straight to data carving. It turns out with HFS+ the files are often not fragmented, so data carving is very successful, but you still don't get any filesystem metadata. I believe XFS is similar to HFS+ in this sense. Data carving would likely have good results, but looking for filesystem metadata remnants is a waste of time. If I'm right, there is not really any research needed on the deleted file recovery side. At the same time, I'm not familiar with forensic tool, free or commercial, that parses the XFS filesystem for live files and filesystem metadata such as timestamps. (I could be wrong, it is not something I've had to research in the last few years.) > Besides, from a conceptual point of view after-the-fact filesystem > based undelete is fundamentally flawed. i.e. the journal is a > write-ahead logging journal and so can only be used to roll the > filesystem state forwardi in time.

I suspect you are assuming the goal is "reliable undelete". The typical goal is the identification of potentially recoverable files. I don't know if parsing the XFS journal can help with that.

In his first paragraph he stated he's a graduate student and his research area is digital forensics. So the discussion about "deleted file recovery" needs to be in the forensics context. As you explain above, and as Greg Freemyer pointed out, looking at filesystem metadata or journals for information that will assist in the recovery of previously deleted files is usually not going to be fruitful. -- Stan From stan@hardwarefreak.com Fri Mar 7 20:22:06 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 0807C7F5E for ; Fri, 7 Mar 2014 20:22:06 -0600 (CST) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id DB9538F804B for ; Fri, 7 Mar 2014 18:22:05 -0800 (PST) X-ASG-Debug-ID: 1394245324-04bdf076f0b6c20001-NocioJ Received: from greer.hardwarefreak.com (mo-65-41-216-221.sta.embarqhsd.net [65.41.216.221]) by cuda.sgi.com with ESMTP id CYGthrsDCuqTRAmS for ; Fri, 07 Mar 2014 18:22:04 -0800 (PST) X-Barracuda-Envelope-From: stan@hardwarefreak.com X-Barracuda-Apparent-Source-IP: 65.41.216.221 X-Barracuda-User-Whitelist: xfs@oss.sgi.com Received: from [192.168.100.53] (gffx.hardwarefreak.com [192.168.100.53]) by greer.hardwarefreak.com (Postfix) with ESMTP id 4290F6C169; Fri, 7 Mar 2014 20:22:04 -0600 (CST) Message-ID: <531A7ED1.2050403@hardwarefreak.com> Date: Fri, 07 Mar 2014 20:22:09 -0600 From: Stan Hoeppner Reply-To: stan@hardwarefreak.com User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:24.0) Gecko/20100101 Thunderbird/24.3.0 MIME-Version: 1.0 To: Shaun Gosse , Yongmin , "xfs@oss.sgi.com" Subject: Re: Hello, I have a question about XFS File System References: <195DE8C60CE24A62A71911FDE0B0DC97@gmail.com> <5318DB01.2040102@hardwarefreak.com> <279D0A265E5D4AF5B099BFAD4E8B1700@gmail.com> <531A4600.7050906@hardwarefreak.com> <8D3FA7645C1CFC4E9E783D22B4C708647305E1F5@P-EXMB2-DC21.corp.sgi.com> X-ASG-Orig-Subj: Re: Hello, I have a question about XFS File System In-Reply-To: <8D3FA7645C1CFC4E9E783D22B4C708647305E1F5@P-EXMB2-DC21.corp.sgi.com> Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: mo-65-41-216-221.sta.embarqhsd.net[65.41.216.221] X-Barracuda-Start-Time: 1394245324 X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 On 3/7/2014 4:40 PM, Shaun Gosse wrote: > Stan, > > If I understand what you're saying here correctly, it sounds like > there would still be a very tiny window where the journal could be > relevant, those "few seconds" before it's committed as you said.

It could be in the log for milliseconds, many minutes, hours, or even days, or months, depending on the rate of metadata write activity. XFS is still primarily for "large and lots". Most organizations using XFS probably don't have idle journal logs, but very active ones. > This does makes me curious in turn about how difficult it would be to > recover journal entries.

How often are forensics experts brought in within minutes, hours, or days of an incident of such magnitude prompting them to be hired? Forensics is typically performed long after the fact, in which case there's almost zero chance any relevant information will be in the filesystem journal. -- Stan From sandeen@sandeen.net Fri Mar 7 21:25:03 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay3.corp.sgi.com [198.149.34.15]) by oss.sgi.com (Postfix) with ESMTP id DB22A7F60 for ; Fri, 7 Mar 2014 21:25:02 -0600 (CST) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay3.corp.sgi.com (Postfix) with ESMTP id 5FB21AC003 for ; Fri, 7 Mar 2014 19:24:58 -0800 (PST) X-ASG-Debug-ID: 1394249093-04cbb054b9171690001-NocioJ Received: from sandeen.net (sandeen.net [63.231.237.45]) by cuda.sgi.com with ESMTP id FnBrxgFdejmYG1uL for ; Fri, 07 Mar 2014 19:24:54 -0800 (PST) X-Barracuda-Envelope-From: sandeen@sandeen.net X-Barracuda-Apparent-Source-IP: 63.231.237.45 Received: from liberator.sandeen.net (liberator.sandeen.net [10.0.0.4]) (using TLSv1 with cipher DHE-RSA-AES128-SHA (128/128 bits)) (No client certificate requested) by sandeen.net (Postfix) with ESMTPSA id 6166365C2845; Fri, 7 Mar 2014 21:24:53 -0600 (CST) Message-ID: <531A8D85.6060307@sandeen.net> Date: Fri, 07 Mar 2014 21:24:53 -0600 From: Eric Sandeen User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:24.0) Gecko/20100101 Thunderbird/24.3.0 MIME-Version: 1.0 To: stan@hardwarefreak.com, Dave Chinner CC: Yongmin , "xfs@oss.sgi.com" Subject: Re: Hello, I have a question about XFS File System References: <195DE8C60CE24A62A71911FDE0B0DC97@gmail.com> <5318DB01.2040102@hardwarefreak.com> <279D0A265E5D4AF5B099BFAD4E8B1700@gmail.com> <531A4600.7050906@hardwarefreak.com> <20140307230915.GS6851@dastard> <531A7BB8.5090201@hardwarefreak.com> X-ASG-Orig-Subj: Re: Hello, I have a question about XFS File System In-Reply-To: <531A7BB8.5090201@hardwarefreak.com> X-Enigmail-Version: 1.6 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[63.231.237.45] X-Barracuda-Start-Time: 1394249093 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.3696 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On 3/7/14, 8:08 PM, Stan Hoeppner wrote: > On 3/7/2014 5:09 PM, Dave Chinner wrote: >> On Fri, Mar 07, 2014 at 04:19:44PM -0600, Stan Hoeppner wrote: >>> Please reply to the mailing list as well as the individual. >>> >>> Note that you stated: >>> >>> '...the concentrated part of mine is "Deleted File Recovery"' >>> >>> On 3/6/2014 10:02 PM, Yongmin wrote: >>>> >>>> Yes! there are no actual file data in journaling part. >>>> >>>> BUT, by analyzing journaling part, we can get a Inode Core Information which was deleted. >>>> In Inode Core, there are many information about the actual data, i.e. start address, file length etc. >>> >>> Analyzing the journal code may inform you about structures, but it won't >>> inform you about on disk locations of the structures and how to find >>> them.

Well, I think that's a good point. "Looking at the log to see if there are any clues for manual recovery" is a very different problem from "Use the log for automated, guaranteed successful undelete" :) -Eric From estelle.seiler@hep-bejune.ch Sat Mar 8 01:33:03 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 1103F7F66 for ; Sat, 8 Mar 2014 01:33:03 -0600 (CST) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id D77508F8037 for ; Fri, 7 Mar 2014 23:33:02 -0800 (PST) X-ASG-Debug-ID: 1394263979-04bdf05dab3a08e0001-NocioJ Received: from HEPEDGE1.hep-bejune.ch (hepedge1.hep-bejune.ch [192.135.153.24]) by cuda.sgi.com with ESMTP id 8Ey0nHGNhCrnGD2x (version=TLSv1 cipher=AES128-SHA bits=128 verify=NO) for ; Fri, 07 Mar 2014 23:33:01 -0800 (PST) X-Barracuda-Envelope-From: estelle.seiler@hep-bejune.ch X-Barracuda-Apparent-Source-IP: 192.135.153.24 Received: from HEPCASHUB1.hep-bejune.ch (192.135.153.211) by HEPEDGE1.hep-bejune.ch (192.135.153.24) with Microsoft SMTP Server (TLS) id 14.3.146.0; Sat, 8 Mar 2014 08:32:38 +0100 Received: from HEPMBX1.hep-bejune.ch ([fe80::4431:d8d4:365e:6147]) by HEPCASHUB1.hep-bejune.ch ([192.135.153.211]) with mapi id 14.03.0146.000; Sat, 8 Mar 2014 08:32:58 +0100 From: Seiler Estelle Subject: =?iso-8859-1?Q?Ozn=E1men=ED_admin_centrum?= Thread-Topic: =?iso-8859-1?Q?Ozn=E1men=ED_admin_centrum?= X-ASG-Orig-Subj: =?iso-8859-1?Q?Ozn=E1men=ED_admin_centrum?= Thread-Index: Ac86oKCP7LwkwfInReCFaUPmcGk/LQ== Date: Sat, 8 Mar 2014 07:32:58 +0000 Message-ID: <14F8BE0D63ABA940BF6D2975FA6F8AEC3088F0@HEPMBX1.hep-bejune.ch> Accept-Language: en-GB, fr-FR, fr-CH, en-US Content-Language: en-GB X-MS-Has-Attach: X-MS-TNEF-Correlator: x-originating-ip: [192.135.153.239] Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 To: Undisclosed recipients:; X-Barracuda-Connect: hepedge1.hep-bejune.ch[192.135.153.24] X-Barracuda-Start-Time: 1394263980 X-Barracuda-Encrypted: AES128-SHA X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.02 X-Barracuda-Spam-Status: No, SCORE=0.02 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=THREAD_INDEX, THREAD_TOPIC X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.3700 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.01 THREAD_INDEX thread-index: AcO7Y8iR61tzADqsRmmc5wNiFHEOig== 0.01 THREAD_TOPIC Thread-Topic: ...(Japanese Subject)...

"forensicator"? I'm so behind on my terminology. :/ Depsite not having some fancy title, I do forensic analysis of filesystem corpses *every day*. I have to do this in far more detail than a typical forensic analysis for data recovery or security breach post-mortem purposes because I've got to find the bug in the metadata that lead to the corruption or data loss in the first place.... > I don't know XFS on disk structure in detail, so I'll comment about > HFS+ and NTFS. [snip] XFS metadata is fully dynamic, so take the problems you have with HFS btree directory structures and apply it to *every* metadata structure in XFS. > As a last resort, data carving tools equivalent to photorec are used. > Photorec depends on the files not being fragmented and also fails to > recover any filesystem metadata such as filenames, timestamps, etc. Well, yes - anyone can grep a disk image for digital signatures and then hope the files have been stored contiguously. More advanced users write utilities like xfs_irecover or xfsr that walk the filesystem looking for inode magic numbers and manually decode the inode metadata themselves to recover the data they reference even when the files are not contiguous. These only work on unconnected inodes, though, because unlinked inodes don't have any metadata in them that is useful: xfs_db> inode 1029 xfs_db> p core.magic = 0x494e core.mode = 0 core.version = 2 core.format = 2 (extents) core.nlinkv2 = 0 core.onlink = 0 core.projid_lo = 0 core.projid_hi = 0 core.uid = 0 core.gid = 0 core.flushiter = 2 core.atime.sec = Sun Mar 9 10:44:22 2014 core.atime.nsec = 821908000 core.mtime.sec = Sun Mar 9 10:44:22 2014 core.mtime.nsec = 821908000 core.ctime.sec = Sun Mar 9 10:45:02 2014 core.ctime.nsec = 273908000 core.size = 0 core.nblocks = 0 core.extsize = 0 core.nextents = 0 core.naextents = 0 core.forkoff = 0 core.aformat = 2 (extents) core.dmevmask = 0 core.dmstate = 0 core.newrtbm = 0 core.prealloc = 0 core.realtime = 0 core.immutable = 0 core.append = 0 core.sync = 0 core.noatime = 0 core.nodump = 0 core.rtinherit = 0 core.projinherit = 0 core.nosymlinks = 0 core.extsz = 0 core.extszinherit = 0 core.nodefrag = 0 core.filestream = 0 core.gen = 1 next_unlinked = null u = (empty) xfs_db> daddr 0x202 xfs_db> p .... 100: 494e0000 02020000 00000000 00000000 00000000 00000000 00000000 00000002 120: 531bab56 30fd5220 531bab56 30fd5220 531bab7e 10538120 00000000 00000000 140: 00000000 00000000 00000000 00000000 00000002 00000000 00000000 00000001 160: ffffffff 00000000 00000000 00000000 00000000 00000000 00000000 00000000 180: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 1a0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 1c0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 1e0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 So, it has non-zero timestamps in it, but everything else is zeroed. IOWs, you can't get any information about what it contained before it was unlinked from it by looking at the unlinked inode on disk. But that wasn't the original question being asked, though. ;) > At the same time, I'm not familiar with forensic tool, free or > commercial, that parses the XFS filesystem for live files and > filesystem metadata such as timestamps. (I could be wrong, it is not > something I've had to research in the last few years.) Finding lost and/or unreferenced *live* metadata is what xfs_repair does.

That's exactly the question I answered: journal parsing is mostly useless for forensic analysis of XFS filesystems with respect to recovery of deleted files.

The above reports all indicate that the taking a page fault while holding the directory ilock is problematic. So have all the other new lockdep reports we've got that have been caused by that change. Realistically, I think that the readdir locking change was fundamentally broken. Why? Because taking page faults while holding the ilock violates the lock order we have for inodes. For regular files, the lock heirarchy is iolock -> page fault -> ilock, and we got rid of the need for the iolock in the inode reclaim path because of all the problems it caused lockdep. Now we've gone and reintroduced that same set of problems - only worse - by allowing the readdir code to take page faults while holding the ilock.... I'd like to revert the change that introduced the ilock into the readdir path, but I suspect that woul dbe an unpopular direction to take. However, we need a solution that doesn't drive us insane with lockdep false positives. IOWs, we need to do this differently - readdir needs to be protected by the iolock, not the ilock, and only the block mapping routines in the readdir code should be protected by the ilock. i.e. the same locking strategy that is used for regular files: iolock protects the contents of the file, the ilock protects the inode metadata. What I think we really need to do is drive the ilock all the way into the block mapping functions of the directory code and to the places where the inode metadata is actually going to be modified. The iolock protects access to the directory data, and logging of changes to those blocks is serialised by the buffer locks, so we don't actually need the inode ilock to serialise access to the directory data - we only need the ilock for modifications to the inode and it's blockmaps itself, same as for regular files. Changing the directory code to handle this sort of locking is going to require a bit of surgery. However, I can see advantages to moving directory data to the same locking strategy as regular file data - locking heirarchies are identical, directory ilock hold times are much reduced, we don't get lockdep whining about taking page faults with the ilock held, etc. A quick hack at to demonstrate the high level, initial step of using the IOLOCK for readdir serialisation. I've done a little smoke testing on it, so it won't die immediately. It should get rid of all the nasty lockdep issues, but it doesn't start to address the deeper restructing that is needed. Thoughts, comments? I'm especially interested in what SGI people have to say here because this locking change was needed for CXFS, and changing the directory locking iheirarchy is probably going to upset CXFS a lot... Cheers, Dave. -- Dave Chinner david@fromorbit.com xfs; holding ilock over readdir is wrong From: Dave Chinner The recent change to the readdir locking made in 40194ec ("xfs: reinstate the ilock in xfs_readdir") for CXFS directory sanity was fundamentally the wrong thing to do. deep in the readdir code we can take page faults in the filldir callback, and so taking a page fault while holding an inode ilock creates a new set of locking issues that lockdep warns all over the place about. The locking order for regularl inodes w.r.t. page faults is io_lock -> pagefault -> mmap_sem -> ilock. The directory readdir code now triggers ilock -> page fault -> mmap_sem. While we cannot deadlock at this point, it inverts all the locking patterns that lockdep normally sees on XFS inodes, and so triggers lockdep. We worked around this with commit 93a8614 ("xfs: fix directory inode iolock lockdep false positive"), but that then just moved the lockdep warning to deeper in the page fault path and triggered on seurity inode locks. Further, if we enter memory reclaim in a readdir path, we now get lockdep warning about potential deadlocks because the ilock is held when we enter reclaim. This, again, is different to a regular file in that we never allow memory reclaim to run while holding the ilock for regular files. Hence lockdep now throws ilock->kmalloc->reclaim->ilock warnings. Basically, the problem is that the ilock is being used to protect the directory data and the inode metadata, whereas for a regular file the iolock protects the data and the ilock protects the metadata. From the VFS perspective, the i_mutex serialises all accesses to the directory data, and so not holding the ilock for readdir doesn't matter. The issue is that CXFS doesn't access directory data via the VFS, so it has no "data serialisaton" mechanism. While the simplest way to fix these problems would simply be to revert the ilock addition made to xfs_readdir,but I figure that would be unpopular with some people. Hence we need a different solution: we should use the iolock to protect readdir against modification races. The ilock can then be used just when the extent list needs to be read, just like we do for regular files. The directory modification code can now take the iolock exclusive when the ilock is also taken, and this then ensures that readdir is correct excluded while modifications are in progress. This would be a straight forward change, except for two things: filestreams and lockdep. The filestream allocator takes the directory iolock and makes assumptions about parent->child locking order of the iolock which will now be invalidated. Hence some changes to the filestreams code is needed to ensure that it never blocks on directory iolocks and deadlocks. instead it needs to fail stream associations when such problems occur. Lockdep is just plain annoying. We have a bug in our handling of the XFS_LOCK_PARENT handling when it comes to locking multiple inodes with that flag set - lockdep classes are exclusive and can't be ORed together to form new classes. And there's only 8 subclasses available. Luckily, we only need the new annotations on the iolock, and we never lok more than 2 of those at once, so there's space available in the iolock lockdep mask to shoehorn in a separate lockdep subclass map for parent based iolocks.

I think the right fix is to stop abusing the iolock in filestreams.

Seems like the iolock could be removed fairly easily by using either of the two options: a) reference count fstrm_item, and just grab a reference to it for each child as well as the parent and insert it multiple times. Kill ->pip. b) only allocate and insert fstrm_items for directories. Find the directory by grabbing an entry off inode->i_dentry and then grabbing the parent. There always should be a dentry around when we allocate blocks, and if none we can just skip out of the filestreams allocator if there's none. For the cases that matter there is. Both mean that the race it tries to protect against using the iolock is remove entirely, and the code becomes more efficient as well. Option a) seems simple to implement, but b) will save a lot more memory and operations when using the filestreams allocator.

Pushing the > ilock down to where it's actually needed is a good idea either way, > though. The issue is that if we push the ilock down to the just the block mapping routines, the directory can be modified while the readdir is in progress. That's the root problem that adding the ilock solved. Now, just pushing the ilock down to protect the bmbt lookups might result in a consistent lookup, but it won't serialise sanely against modifications. i.e. readdir only walks one dir block at a time but it maps multiple blocks for readahead and keeps them in a local array and doesn't validate them again before issuing read o nthose buffers. Hence at a high level we currently have to serialise readdir against all directory modifications. The only other option we might have is to completely rewrite the directory readahead code not to cache mappings. If we use the ilock purely for bmbt lookup and buffer read, then the ilock will serialise against modification, and the buffer lock will stabilise the buffer until the readdir moves to the next buffer and picks the ilock up again to read it. That would avoid the need for high level serialisation, but it's a lot more work than using the iolock to provide the high level serialisation and i'm still not sure it's 100% safe. And I've got no idea if it would work for CXFS. Hopefully someone from SGI will chime in here.... > > This would be a straight forward change, except for two things: > > filestreams and lockdep.

These are providing the high level readdir vs modification serialisation protection. And we have to unlock it on transaction commit, which is why it needs to be added to the xfs_trans_ijoin() calls...

Yeah, b) seems like the way to simplify it - the filestreams code really only needs to track the parent/ag relationship rather than the child/parent relationship if there is a reliable way of determining the parent from the child. What do we do with hardlinked files in this case? I'm happy to say "too bad" for these files mainly because the filestream allocator is aimed at associating multiple file creations together, so hard links really don't matter AFAICT...

Protecting directory contents with the iolock and pushing the ilock down to protect the directory block mapping functions seems like a good strategy to me. In this area I think it's good to treat directories the same as regular files. I have not had a very close look yet... and couldn't find where we take a fault with irqs disabled. Maybe something out of a workqueue?

Lockdep is complaining about having different page fault lock heirarchies for regular files versus directories. It's too stupid to understand that the directory and regular inodes have differnet lock classes and so therefore this: > [ 96.098894] Possible unsafe locking scenario: > > [ 96.099795] CPU0 CPU1 > [ 96.100234] ---- ---- > [ 96.100666] lock(&(&ip->i_lock)->mr_lock); > [ 96.101158] lock(&mm->mmap_sem); > [ 96.101597] lock(&(&ip->i_lock)->mr_lock); > [ 96.102030] lock(&mm->mmap_sem); is impossible, because what it really is: CPU0 CPU1 ilock (IS_DIR) lock(mmap_sem) ilock(IS_REG) lock(mmap_sem) cannot deadlock because there two different inode locks involved here. So, to shut lockdep up, we've got to fundamentally alter the locking strategy. The current code is not broken, but we've now got to jump throw complex hoops to make the locking validator understand that it's not broken. This is a great example of how lockdep can be considered harmful....

Also in leaf and node formats a single modification can change multiple buffers, so I suspect the buffer lock isn't enough serialization to maintain a consistent directory in the face of multiple readers and writers.

Ok, it seems like a good strategy, but does it work for CXFS? What about the other option of a combination of ilock for mapping and read, and buffer locks for stabilisation? > In this area I think it's good to treat directories the > same as regular files. I have not had a very close look yet... and > couldn't find where we take a fault with irqs disabled. Maybe something > out of a workqueue? Workqueues don't run with interrupts disabled. Yes, we take inode locks in workqueue context (e.g. AIL tail pushing), but that's not what is being warned about here. And the page fault only comes from the filldir callback which runs copy_to_user(), and that most definitely does not occur in interrupt context. FWIW, it's invalid to take the ilock in interrupt context because it's a sleeping lock without using trylock semantics. If you use "trylock" semantics, then lockdep doesn't complain about that because it can't deadlock. I *think* that lockdep is complaining about reclaim contexts, not interrupts, and it's issuing this "interrupts disabled" deadlocks because the memory reclaim state code is piggy-backed on the interrupt state tracking within lockdep. Either way, though, lockdep is wrong.

Right, but we don't care about anything other than the leaf block that we are currently reading is consistent when the read starts and is consistent across the entire processing. i.e. if the leaf is locked by readdir, then the modification is completely stalled until the readdir lets it go. And readdir then can't get the next buffer until the modification is complete because it blocks on the ilock to get the next mapping and buffer....

Thanks, Let's take a look at my test flows: step1: write some random data to fs tree and then create a snapshot of fs tree. step2: also try to write some random data to newly created snapshot. step3: enable quota and wait quota rescan finished.(btrfs quota rescan -w) step4: remove all files and sync btrfs filesystem. So i did a simple test that if we don't create snapshot here, i get qgroup accounting right here, so i think it is realted to qgroup accounting that differs 'refer' and 'excl'.

We have two PowerVault MD3260e's each configured with a 30 disk RAID10 (15 RAID groups) exposed to our server. Segment size is 128K (in Dell's world I'm not sure if this means my stripe width is 128K*15?) Have set up a concatenated LVM volume on top of these two "virtual disks" (with lvcreate -i 2). By default LVM says it's used a stripe width of 64K. # lvs -o path,size,stripes,stripe_size Path LSize #Str Stripe /dev/agsfac_vg00/lv00 100.00t 2 64.00k Unsure if these defaults should be adjusted. I'm trying to figure out the appropriate sw/su values to use per: http://xfs.org/index.php/XFS_FAQ#Q:_How_to_calculate_the_correct_sunit.2Cswidth_values_for_optimal_performance Am considering either just going with defaults (XFS should pull from LVM I think) or doing something like sw=2,su=128K. However, maybe I should be doing sw=2,su=1920K? And perhaps my LVM stripe width should be adjusted?

Thanks, -Jeff From: Jie Liu On old kernel we return EINVAL if hit the limits of maximum number of ACLs but return E2BIG on new kernel, which cause the current test fails on new kernel as the output is mismatch to the goldens.

It appears we've lost an error check associated with allocation failure in xfs_freed_extent_alloc() (here and at other callers). The current code looks like it handles this by marking the transaction as synchronous. Have we avoided the need for this by using kmem_zone_alloc()? I guess it looks like the sleep param will cause it to continue to retry... > + } > + return error; > +} > diff --git a/fs/xfs/xfs_alloc.h b/fs/xfs/xfs_alloc.h > index feacb06..4aa7f8c 100644 > --- a/fs/xfs/xfs_alloc.h > +++ b/fs/xfs/xfs_alloc.h > @@ -122,6 +122,17 @@ typedef struct xfs_alloc_arg { > xfs_fsblock_t firstblock; /* io first block allocated */ > } xfs_alloc_arg_t; > > +struct xfs_freed_extent { > + struct rb_node rb_node; /* ag by-bno indexed search tree */ > + struct list_head list; /* transaction busy extent list */ > + xfs_agnumber_t agno; > + xfs_agblock_t bno; agbno? > + xfs_extlen_t length; > + unsigned int flags; > +#define XFS_EXTENT_DISCARDED 0x01 /* undergoing a discard op. */ > +#define XFS_EXTENT_SKIP_DISCARD 0x02 /* do not discard */ > +}; > + > /* > * Defines for userdata > */ > @@ -210,6 +221,11 @@ xfs_free_extent( > xfs_fsblock_t bno, /* starting block number of extent */ > xfs_extlen_t len); /* length of extent */ > > +int > +__xfs_free_extent( > + struct xfs_trans *tp, > + struct xfs_freed_extent *free); > + > int /* error */ > xfs_alloc_lookup_le( > struct xfs_btree_cur *cur, /* btree cursor */ > @@ -231,4 +247,13 @@ xfs_alloc_get_rec( > xfs_extlen_t *len, /* output: length of extent */ > int *stat); /* output: success/failure */ > > +struct xfs_freed_extent * > +xfs_freed_extent_alloc( > + xfs_agnumber_t agno, > + xfs_agblock_t bno, > + xfs_extlen_t len, > + unsigned int flags); > + > +extern kmem_zone_t *xfs_freed_extent_zone; > + > #endif /* __XFS_ALLOC_H__ */ > diff --git a/fs/xfs/xfs_alloc_btree.c b/fs/xfs/xfs_alloc_btree.c > index cc1eadc..ce3041a 100644 > --- a/fs/xfs/xfs_alloc_btree.c > +++ b/fs/xfs/xfs_alloc_btree.c > @@ -107,21 +107,24 @@ xfs_allocbt_free_block( > struct xfs_btree_cur *cur, > struct xfs_buf *bp) > { > + struct xfs_trans *tp = cur->bc_tp; > struct xfs_buf *agbp = cur->bc_private.a.agbp; > struct xfs_agf *agf = XFS_BUF_TO_AGF(agbp); > + struct xfs_freed_extent *free; > xfs_agblock_t bno; > int error; > > bno = xfs_daddr_to_agbno(cur->bc_mp, XFS_BUF_ADDR(bp)); > - error = xfs_alloc_put_freelist(cur->bc_tp, agbp, NULL, bno, 1); > + error = xfs_alloc_put_freelist(tp, agbp, NULL, bno, 1); > if (error) > return error; > > - xfs_extent_busy_insert(cur->bc_tp, be32_to_cpu(agf->agf_seqno), bno, 1, > - XFS_EXTENT_BUSY_SKIP_DISCARD); > - xfs_trans_agbtree_delta(cur->bc_tp, -1); Was this supposed to go away? > + free = xfs_freed_extent_alloc(be32_to_cpu(agf->agf_seqno), bno, 1, > + XFS_EXTENT_SKIP_DISCARD); > + xfs_extent_busy_insert(tp, free); > + list_add(&free->list, &tp->t_busy); > > - xfs_trans_binval(cur->bc_tp, bp); > + xfs_trans_binval(tp, bp); > return 0; > } > > diff --git a/fs/xfs/xfs_bmap.c b/fs/xfs/xfs_bmap.c > index 5b6092e..9c2c00c 100644 > --- a/fs/xfs/xfs_bmap.c > +++ b/fs/xfs/xfs_bmap.c > @@ -50,7 +50,7 @@ > #include "xfs_filestream.h" > > > -kmem_zone_t *xfs_bmap_free_item_zone; > +kmem_zone_t *xfs_freed_extent_zone; > > /* > * Miscellaneous helper functions > @@ -588,10 +588,6 @@ xfs_bmap_validate_ret( > #endif /* DEBUG */ > > /* > - * bmap free list manipulation functions > - */ > - > -/* > * Add the extent to the list of extents to be free at transaction end. > * The list is maintained sorted (by block number). > */ This comment could be fixed now that the sort is deferred. > @@ -602,58 +598,22 @@ xfs_bmap_add_free( > xfs_bmap_free_t *flist, /* list of extents */ > xfs_mount_t *mp) /* mount point structure */ > { > - xfs_bmap_free_item_t *cur; /* current (next) element */ > - xfs_bmap_free_item_t *new; /* new element */ > - xfs_bmap_free_item_t *prev; /* previous element */ > -#ifdef DEBUG > - xfs_agnumber_t agno; > - xfs_agblock_t agbno; > + xfs_agnumber_t agno = XFS_FSB_TO_AGNO(mp, bno); > + xfs_agblock_t agbno = XFS_FSB_TO_AGBNO(mp, bno); > + struct xfs_freed_extent *new; > > ASSERT(bno != NULLFSBLOCK); > ASSERT(len > 0); > ASSERT(len <= MAXEXTLEN); > ASSERT(!isnullstartblock(bno)); > - agno = XFS_FSB_TO_AGNO(mp, bno); > - agbno = XFS_FSB_TO_AGBNO(mp, bno); > ASSERT(agno < mp->m_sb.sb_agcount); > ASSERT(agbno < mp->m_sb.sb_agblocks); > ASSERT(len < mp->m_sb.sb_agblocks); > ASSERT(agbno + len <= mp->m_sb.sb_agblocks); > -#endif > - ASSERT(xfs_bmap_free_item_zone != NULL); > - new = kmem_zone_alloc(xfs_bmap_free_item_zone, KM_SLEEP); > - new->xbfi_startblock = bno; > - new->xbfi_blockcount = (xfs_extlen_t)len; > - for (prev = NULL, cur = flist->xbf_first; > - cur != NULL; > - prev = cur, cur = cur->xbfi_next) { > - if (cur->xbfi_startblock >= bno) > - break; > - } > - if (prev) > - prev->xbfi_next = new; > - else > - flist->xbf_first = new; > - new->xbfi_next = cur; > - flist->xbf_count++; > -} > > -/* > - * Remove the entry "free" from the free item list.

If however hitting the dcache hard in this path causes problems with might have to use a different strategy here. diff --git a/fs/xfs/xfs_filestream.c b/fs/xfs/xfs_filestream.c index 12b6e77..2ffb10a 100644 --- a/fs/xfs/xfs_filestream.c +++ b/fs/xfs/xfs_filestream.c @@ -32,100 +32,27 @@ #include "xfs_filestream.h" #include "xfs_trace.h" -#ifdef XFS_FILESTREAMS_TRACE - -ktrace_t *xfs_filestreams_trace_buf; - -STATIC void -xfs_filestreams_trace( - xfs_mount_t *mp, /* mount point */ - int type, /* type of trace */ - const char *func, /* source function */ - int line, /* source line number */ - __psunsigned_t arg0, - __psunsigned_t arg1, - __psunsigned_t arg2, - __psunsigned_t arg3, - __psunsigned_t arg4, - __psunsigned_t arg5) -{ - ktrace_enter(xfs_filestreams_trace_buf, - (void *)(__psint_t)(type | (line << 16)), - (void *)func, - (void *)(__psunsigned_t)current_pid(), - (void *)mp, - (void *)(__psunsigned_t)arg0, - (void *)(__psunsigned_t)arg1, - (void *)(__psunsigned_t)arg2, - (void *)(__psunsigned_t)arg3, - (void *)(__psunsigned_t)arg4, - (void *)(__psunsigned_t)arg5, - NULL, NULL, NULL, NULL, NULL, NULL); -} - -#define TRACE0(mp,t) TRACE6(mp,t,0,0,0,0,0,0) -#define TRACE1(mp,t,a0) TRACE6(mp,t,a0,0,0,0,0,0) -#define TRACE2(mp,t,a0,a1) TRACE6(mp,t,a0,a1,0,0,0,0) -#define TRACE3(mp,t,a0,a1,a2) TRACE6(mp,t,a0,a1,a2,0,0,0) -#define TRACE4(mp,t,a0,a1,a2,a3) TRACE6(mp,t,a0,a1,a2,a3,0,0) -#define TRACE5(mp,t,a0,a1,a2,a3,a4) TRACE6(mp,t,a0,a1,a2,a3,a4,0) -#define TRACE6(mp,t,a0,a1,a2,a3,a4,a5) \ - xfs_filestreams_trace(mp, t, __func__, __LINE__, \ - (__psunsigned_t)a0, (__psunsigned_t)a1, \ - (__psunsigned_t)a2, (__psunsigned_t)a3, \ - (__psunsigned_t)a4, (__psunsigned_t)a5) - -#define TRACE_AG_SCAN(mp, ag, ag2) \ - TRACE2(mp, XFS_FSTRM_KTRACE_AGSCAN, ag, ag2); -#define TRACE_AG_PICK1(mp, max_ag, maxfree) \ - TRACE2(mp, XFS_FSTRM_KTRACE_AGPICK1, max_ag, maxfree); -#define TRACE_AG_PICK2(mp, ag, ag2, cnt, free, scan, flag) \ - TRACE6(mp, XFS_FSTRM_KTRACE_AGPICK2, ag, ag2, \ - cnt, free, scan, flag) -#define TRACE_UPDATE(mp, ip, ag, cnt, ag2, cnt2) \ - TRACE5(mp, XFS_FSTRM_KTRACE_UPDATE, ip, ag, cnt, ag2, cnt2) -#define TRACE_FREE(mp, ip, pip, ag, cnt) \ - TRACE4(mp, XFS_FSTRM_KTRACE_FREE, ip, pip, ag, cnt) -#define TRACE_LOOKUP(mp, ip, pip, ag, cnt) \ - TRACE4(mp, XFS_FSTRM_KTRACE_ITEM_LOOKUP, ip, pip, ag, cnt) -#define TRACE_ASSOCIATE(mp, ip, pip, ag, cnt) \ - TRACE4(mp, XFS_FSTRM_KTRACE_ASSOCIATE, ip, pip, ag, cnt) -#define TRACE_MOVEAG(mp, ip, pip, oag, ocnt, nag, ncnt) \ - TRACE6(mp, XFS_FSTRM_KTRACE_MOVEAG, ip, pip, oag, ocnt, nag, ncnt) -#define TRACE_ORPHAN(mp, ip, ag) \ - TRACE2(mp, XFS_FSTRM_KTRACE_ORPHAN, ip, ag); - - -#else #define TRACE_AG_SCAN(mp, ag, ag2) #define TRACE_AG_PICK1(mp, max_ag, maxfree) #define TRACE_AG_PICK2(mp, ag, ag2, cnt, free, scan, flag) -#define TRACE_UPDATE(mp, ip, ag, cnt, ag2, cnt2) #define TRACE_FREE(mp, ip, pip, ag, cnt) #define TRACE_LOOKUP(mp, ip, pip, ag, cnt) -#define TRACE_ASSOCIATE(mp, ip, pip, ag, cnt) -#define TRACE_MOVEAG(mp, ip, pip, oag, ocnt, nag, ncnt) -#define TRACE_ORPHAN(mp, ip, ag) -#endif static kmem_zone_t *item_zone; -/* - * Structure for associating a file or a directory with an allocation group. - * The parent directory pointer is only needed for files, but since there will - * generally be vastly more files than directories in the cache, using the same - * data structure simplifies the code with very little memory overhead. - */ -typedef struct fstrm_item -{ - xfs_agnumber_t ag; /* AG currently in use for the file/directory. */ - xfs_inode_t *ip; /* inode self-pointer. */ - xfs_inode_t *pip; /* Parent directory inode pointer. */ -} fstrm_item_t; +struct xfs_fstrm_item { + struct xfs_mount *mp; + xfs_agnumber_t ag; /* AG in use for this directory */ +}; + +enum xfs_fstrm_alloc { + XFS_PICK_USERDATA = 1, + XFS_PICK_LOWSPACE = 2, +}; /* * Allocation group filestream associations are tracked with per-ag atomic - * counters.

And in the case of the normal bmap free path we just splice the list from the bmap flist into the transaction, so we remove the add inside xfs_extent_busy_insert and move it to the callers, so thast the bmap free path can batch it. > It appears we've lost an error check associated with allocation failure > in xfs_freed_extent_alloc() (here and at other callers).

That's what the old bmap freelist path did, and for that case we can't really handle a failure as we are in a dirty transaction that we would have to abort. For the old extent_busy structure the failure wasn't fatal, but we got rid of that allocation entirely for the fast path. > > +struct xfs_freed_extent { > > + struct rb_node rb_node; /* ag by-bno indexed search tree */ > > + struct list_head list; /* transaction busy extent list */ > > + xfs_agnumber_t agno; > > + xfs_agblock_t bno; > > agbno?

Because we the compare callback returns an int, and type promotion in C will give us a wrong result if we "simplify" compare to 64-bit values.

You say at the top that you created a concatenation, but at the bottom you say LVM stripe. So first tell us which one you actually want, because the XFS alignment is radically different for each. Then tell us why you must use LVM instead of md. md has fewer problems/limitations for stripes and concat than LVM, and is much easier to configure. -- Stan From bfoster@redhat.com Wed Mar 12 07:36:00 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 6C7ED7F62 for ; Wed, 12 Mar 2014 07:36:00 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay1.corp.sgi.com (Postfix) with ESMTP id 575488F808E for ; Wed, 12 Mar 2014 05:36:00 -0700 (PDT) X-ASG-Debug-ID: 1394627757-04cbb054b82a5840001-NocioJ Received: from mx1.redhat.com (mx1.redhat.com [209.132.183.28]) by cuda.sgi.com with ESMTP id Vt0PTatzFRKWOCkO for ; Wed, 12 Mar 2014 05:35:59 -0700 (PDT) X-Barracuda-Envelope-From: bfoster@redhat.com X-Barracuda-Apparent-Source-IP: 209.132.183.28 X-ASG-Whitelist: Client Received: from int-mx11.intmail.prod.int.phx2.redhat.com (int-mx11.intmail.prod.int.phx2.redhat.com [10.5.11.24]) by mx1.redhat.com (8.14.4/8.14.4) with ESMTP id s2CCZYJq006202 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=OK); Wed, 12 Mar 2014 08:35:34 -0400 Received: from bfoster.bfoster ([10.18.41.237]) by int-mx11.intmail.prod.int.phx2.redhat.com (8.14.4/8.14.4) with ESMTP id s2CCZXXr027750; Wed, 12 Mar 2014 08:35:33 -0400 Received: by bfoster.bfoster (Postfix, from userid 1000) id 8697E123AB2; Wed, 12 Mar 2014 08:35:32 -0400 (EDT) Date: Wed, 12 Mar 2014 08:35:32 -0400 From: Brian Foster To: Christoph Hellwig Cc: xfs@oss.sgi.com Subject: Re: [PATCH] xfs: merge xfs_bmap_free_item and xfs_extent_busy Message-ID: <20140312123532.GA19329@bfoster.bfoster> X-ASG-Orig-Subj: Re: [PATCH] xfs: merge xfs_bmap_free_item and xfs_extent_busy References: <20140307105535.GA7850@infradead.org> <20140311153135.GA37254@bfoster.bfoster> <20140312104058.GB4167@infradead.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20140312104058.GB4167@infradead.org> User-Agent: Mutt/1.5.21 (2010-09-15) X-Scanned-By: MIMEDefang 2.68 on 10.5.11.24 X-Barracuda-Connect: mx1.redhat.com[209.132.183.28] X-Barracuda-Start-Time: 1394627757 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 On Wed, Mar 12, 2014 at 03:40:58AM -0700, Christoph Hellwig wrote: > On Tue, Mar 11, 2014 at 11:31:38AM -0400, Brian Foster wrote: > > > + xfs_extent_busy_insert(tp, free); > > > + list_add(&free->list, &tp->t_busy); > > > > If I follow correctly, the list_add() is removed from > > xfs_extent_busy_insert() because we use the list field for the bmap > > flist as well as the t_busy list. > > Indeed.

Hi, Please CC me on any responses; I don't subscribe to this list. I ran into a possible XFS bug while doing some Oracle benchmarking. My tes= t system is running a 3.14.0-rc3+ kernel built from the for-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git on 2014-02-19 (last commit 1342f11e713792e53e4b7aa21167fe9caca81c4a). The XFS instance in question is 200 GB and should have all default parameters (mkfs.xfs /dev/mapper/). It contains Oracle binaries and trace files. At the time the issue occurred I had been running Oracle with SQL*NET server tracing enabled. The affected XFS had filled up 100% with trace files several times; I was periodically executing rm -f * in the trace file directory, which would reduce the file system occupancy from 100% to 3%. I had an Oracle load generating tool running, so new log files were being created with some frequency. The issue occurred during one of my rm -f * executions; afterwards the file system would only produce errors.

Accordingly I rebooted. You are the second person in 2-3 weeks to hit this unmount issue. Unmatched EFI in the AIL keeps the unmount from completing. Jeff are you still looking at this? Here and in xlog_recover_process_efi(), the EFD will never happened because of the xfs_free_extent error. A manual removal of the EFI from the AIL in these cases has to be done. Christoph's proposed EFI/EFD recovery changed will not change the need to remove the EFI from the AIL in recovery because at this point he does put the EFI on the AIL. Case 2 is a bit trickier. The EFI has a matching EFD. The EFI makes it to AIL but the EFD is on the CIL when there is a forced shutdown. The EFD will not remove the EFI in this case. We cannot check if the EFI on the AIL in the iop_{committed | unlink} for EFI/EFD pairs that on the CIL at forced shutdown because the check would be a use after free on the EFI. The EFD being aborted on a bad xlog buffer write is another path, but that is pretty much the same as the case #2. > I captured a post-reboot xfs_metadump before attempting any other operations > on the partition.

Caller 0xffffffffa04c4905 So, freeing a range that is already partially free. The problem appears to be in AG 15, according to the repair output. > https://dl.dropboxusercontent.com/u/31522929/xfs-double-free-xfs_metadump-before-repair.gz AGF 15 is full: xfs_db> agf 15 xfs_db> p magicnum = 0x58414746 versionnum = 1 seqno = 15 length = 3276783 bnoroot = 1 cntroot = 2 bnolevel = 1 cntlevel = 1 flfirst = 0 fllast = 3 flcount = 4 freeblks = 1 longest = 1 btreeblks = 0 uuid = 00000000-0000-0000-0000-000000000000 lsn = 0 crc = 0 And the one free block (other than the minimum 4 on teh AGFL) is: xfs_db> p magic = 0x41425442 level = 0 numrecs = 1 leftsib = null rightsib = null recs[1] = [startblock,blockcount] 1:[3119876,1] But: data fork in ino 940862056 claims dup extent, off - 11, start - 58836692, cnt 1 correcting nextents for inode 940862056 bad data fork in inode 940862056 would have cleared inode 940862056 the block number here is in AG 14, which has much more free space: xfs_db> p magicnum = 0x58414746 versionnum = 1 seqno = 14 length = 3276783 bnoroot = 1 cntroot = 2 bnolevel = 1 cntlevel = 1 flfirst = 42 fllast = 45 flcount = 4 freeblks = 2092022 longest = 2078090 btreeblks = 0 which is in 2 extents: xfs_db> a bnoroot xfs_db> p magic = 0x41425442 level = 0 numrecs = 2 leftsib = null rightsib = null recs[1-2] = [startblock,blockcount] 1:[102466,13932] 2:[116476,2078090] xfs_db> convert agno 14 agbno 102466 fsb 0x3819042 (58822722) xfs_db> convert agno 14 agbno 116476 fsb 0x381c6fc (58836732) and so 58836692 is just short of the second free space. Looking at all the other dup extent claims, they a remostly adjacent to the left edge of these two free spaces. No surprise - that's the way allocation occurs. So, we've got a state where the allocation btree contains a corruption, so a shutdown occurs. The log has captured that corruption when it was made, so log recovery reintroduces that corruption. And so when the extent is freed after log recovery, the corruption is tripped over again. There's two checkpoints in the log, both very small. The last modification to AGI 14 is there before it: BUF: cnt:2 total:2 a:0x669350 len:24 a:0x6693d0 len:128 BUF: #regs:2 start blkno:0x15dff891 len:1 bmap size:1 flags:0x2800 AGF Buffer: (XAGF) ver:1 seq#:14 len:3276783 root BNO:1 CNT:2 level BNO:1 CNT:1 1st:42 last:45 cnt:4 freeblks:2092020 longest:2078090 As is the freespace btree buffer modification: BUF: cnt:2 total:2 a:0x669460 len:24 a:0x6694e0 len:128 BUF: #regs:2 start blkno:0x15dff898 len:8 bmap size:1 flags:0x2000 BUF DATA 0 42544241 4000000 ffffffff ffffffff cb620100 1000000 fc7c0100 2000000 magic = BTBA level = 0 numrecs = 4 leftsib = NULLFSBLOCK rightsib = NULLFSBLOCK rec[0] = 0x162cb, 1 (90827,1) rec[1] = 0x17cfc, 2 (97532,1) 8 47900100 67360000 fcc60100 8ab51f00 71ff3100 5000000 71ff3100 5000000 rec[2] = 0x19047, 0x3667 (102471,13927) rec[3] = 0x1c6fc, 0x1fb58a (116476,2078090) so, from the pre-recovery case above, we've got two new freespaces in rec[0-1], rec[2] has 5 blocks removed from the left edge, and rec[3] is unchanged. Confirming the ABTC buffer contains the same extents: BUF: cnt:2 total:2 a:0x669570 len:24 a:0x6695f0 len:128 BUF: #regs:2 start blkno:0x15dff8a0 len:8 bmap size:1 flags:0x2000 BUF DATA 0 43544241 4000000 ffffffff ffffffff cb620100 1000000 fc7c0100 2000000 magic = CTBA level = 0 numrecs = 4 leftsib = NULLFSBLOCK rightsib = NULLFSBLOCK rec[0] = 0x162cb, 1 (90827,1) rec[1] = 0x17cfc, 2 (97532,1) 8 47900100 67360000 fcc60100 8ab51f00 71ff3100 5000000 71ff3100 5000000 rec[2] = 0x19047, 0x3667 (102471,13927) rec[3] = 0x1c6fc, 0x1fb58a (116476,2078090) 10 8ca0100 8000000 71ff3100 5000000 71ff3100 5000000 71ff3100 5000000 18 71ff3100 5000000 71ff3100 5000000 71ff3100 5000000 71ff3100 5000000 It does. So the btrees contain consistent information, and so it's unlikely that we have a free space btree corruption in the log. So let's look at what was freed: The EFI/EFDs in the log are: EFI: cnt:1 total:1 a:0x668670 len:32 EFI: #regs:1 num_extents:1 id:0xffff881496024af0 (s: 0x38162cb, l: 1) EFD: cnt:1 total:1 a:0x6684d0 len:32 EFD: #regs: 1 num_extents: 1 id: 0xffff881496024af0 .... EFI: cnt:1 total:1 a:0x667da0 len:32 EFI: #regs:1 num_extents:1 id:0xffff8814960244b0 (s: 0x3817cfc, l: 1) EFD: cnt:1 total:1 a:0x65fbd0 len:32 EFD: #regs: 1 num_extents: 1 id: 0xffff8814960244b0 .... EFI: cnt:1 total:1 a:0x669250 len:32 EFI: #regs:1 num_extents:1 id:0xffff881496024000 (s: 0x3817cfd, l: 1) EFD: cnt:1 total:1 a:0x6692d0 len:32 EFD: #regs: 1 num_extents: 1 id: 0xffff881496024000 These are all in ag#14, and have agbnos of 0x162cb, 0x17cfc and 0x17cfd. This corresponds exactly to the two new records in the AG btree. The one remaining EFI doesn't have an EFD in th elog, so this is what is being replayed: EFI: cnt:1 total:1 a:0x669f40 len:32 EFI: #regs:1 num_extents:1 id:0xffff881496024640 (s: 0x3869ff9, l: 1) Which is at agbno 0x69ff9 (434169). That's off to the right of the start of the last freespace range in rec[3]. rec[3] starts at 0x1c6fc and ends at 0x1fb58a. That means this efi clearly lands inside that freespace range - it's not an edge case, it's deep in the interior of the freespace range. The inode logged just before the EFI - likely it's owner: INO: cnt:2 total:2 a:0x668040 len:56 a:0x667fb0 len:96 INODE: #regs:2 ino:0x3862d698 flags:0x1 dsize:0 CORE inode: magic:IN mode:0x81b0 ver:2 format:2 onlink:0 uid:1001 gid:1001 nlink:0 projid:0 atime:1394495104 mtime:1394495104 ctime:1394554526 flushiter:1 size:0x0 nblks:0x0 exsize:0 nextents:0 anextents:0 forkoff:13 dmevmask:0x0 dmstate:0 flags:0x0 gen:-121998876 Is an unlinked inode that has had all it's block removed. Yup - it's on the unlinked list: agi unlinked bucket 24 is 6477464 in ag 14 (inode=946001560) So, prior to recovery, what did it contain? it's got 287 bytes of date, and a single extent: u.bmx[0] = [startoff,startblock,blockcount,extentflag] 0:[0,59154425,1,0] xfs_db> convert fsb 59154425 agno 0xe (14) xfs_db> convert fsb 59154425 agbno 0x69ff9 (434169) Ok, so the corruption, whatever it was, happened a long time ago, and it's only when removing the file that it was tripped over. There's nothing more I can really get from this - the root cause of the corruption is long gone.

The inodes for O_TMPFILE files are are marked with a special flag I_LINKABLE and have a zero link count. To support this in XFS, xfs_link() detects if this flag I_LINKABLE is set and behaves appropriately when detected. So in this case, its transaciton reservation takes into account the additional overhead of removing the inode from the unlinked list. Then the inode is removed from the unlinked list and the directory entry is added. Finally its link count is bumped accordingly.

In contrast to xfs_create(), xfs_create_tmpfile() has a different log reservation to the regular file creation because there is no directory modification, and doesn't check if an entry can be added to the directory, but the reservation quotas is required appropriately, and finally its inode is added to the unlinked list. xfs_vn_tmpfile() add one O_TMPFILE method to VFS interface and directly invoke xfs_create_tmpfile().

Lukas, I have merged patches 4 and 6 into the xfs-collapse-branch.

Hi Dave, that's great thanks! Btw you probably meant branch xfs-collapse-range and those patches are already based on that branch so it should apply cleanly. Now we have to figure out the order in which we're going to take zero-range and collapse-range into ext4.

There's also no reason to exit if there is an error, because the rest of the test does not depend on $testfile being removed. The golden output comparison will then cause the test to fail...

The checking for disconnected inodes is a side effect of using no-modify mode - if it was a real repair that inode would be trashed, not seen as a disconnected inode. Hence I think this is really checking for the wrong thing...

This seems pretty stupid, and it's certainly documented or guaraunteed to do this, nor is it particularly useful, except in the case where the file system was mounted rw and is getting remounted read-only. However, it's possible that there might be some file systems that are actually depending on this behavior. In most file systems, it's probably fine to only call sync_filesystem() when transitioning from read-write to read-only, and there are some file systems where this is not needed at all (for example, for a pseudo-filesystem or something like romfs).

Yes, misused the term concatenation. Striping is what I'm afer (want to use all of my LUNs equally). I don't know that I necessarily need to use LVM here. No need for snapshots, just after the best "performance" for multiple NAS sourced (via Samba) sequential write or read streams (but not read/write at the same time). My setup is as follows right now: MD3260_1 -> Disk Group 0 (RAID10 - 15 RG's, 128K segment size) -> 2 Virtual Disks (one per controller) MD3260_2 -> Disk Group 0 (RAID10 - 15 RG's, 128K segment size) -> 2 Virtual Disks (one per controller) So I see four equally sized LUNs on my RHEL box, each with one active path and one passive path (using Linux MPIO). I'll set up a striped md array across these four LUNs using a 128K chunk size. Things work pretty well with the xfs default, so may stick with that, but to try and get it as "right" as possible, I'm thinking I should be using a su=128k value, but am not sure on the sw value. It's either: - 4 (four LUNs as far as my OS is concerned) - 30 (15 RAID groups per MD3260) I'm thinking probably 4 is the right answer since the RAID groups on my PowerVaults are all abstracted.

Upon restarting my testing I immediately hit this error again (or a very similar one in any case). I suspect that the corruption you've noted was not properly repaired by xfs_repair. I captured all the same data as before, as well as an xfs_metadump from after the xfs_repair.

Ah, you wanted me to fix the cil_push error issue that leaks ctx and does not wake up the waiters. This is only a side issue to that. We can easily patch the xfs_bmap_finish() and xlog_recover_process_efis() code. I have that patch and tested it. But it does not cover the cases of a cil push error nor the successful xfs_bmap_finish() and the EFI is in the AIL but the EFD is discarded. The most correct thing to do is clear the EFI from the AIL in the abort paths of xfs_efd_item_committed() and xfs_efd_item_unlock(), but those will be called many times and would be overkill. A less correct but easier would be clear the EFIs from the AIL once in xfs_unmountfs() after the last force of the log and before the xfs_ail_push_all_sync(). Since the EFI are removed very late, then we don't have to special case the removal in xfs_bmap_finish() and the xlog_recover_process_efis(). This is why I was waiting to see what Jeff wanted to do. If I hear no strong objection, I intend to put the clearing EFI on the AIL for each situation: the abort cases of the efd iop routines, in xfs_bmap_finish() and the xlog_recover_process_efis(). --Mark.

Hum, I'd avoid this excercise at least for filesystem where sync_filesystem() is obviously useless - proc, debugfs, pstore, devpts, also always read-only filesystems such as isofs, qnx4, qnx6, befs, cramfs, efs, freevxfs, romfs, squashfs. I think you can find a couple more which clearly don't care about sync_filesystem() if you look a bit closer.

It's probably AG 14 again. EFI: EFI: cnt:1 total:1 a:0x19c77b0 len:48 EFI: #regs:1 num_extents:2 id:0xffff880f8011c640 (s: 0x3816a3b, l: 112) (s: 0x3817cb1, l: 1920) So, two extents being freed: xfs_db> convert fsb 0x3816a3b agno 0xe (14) xfs_db> convert fsb 0x3816a3b agbno 0x16a3b (92731) xfs_db> convert fsb 0x3817cb1 agbno 0x17cb1 (97457) Surrounding free space regions: 66:[92551,180] 67:[92856,2] -> used space range [92731,125] ... 172:[97415,42] 173:[97622,4] -> used space range [97457,65] So the first extent is good. The second, however, aligns correctly to the free space region to the left, but massively overruns the used space region which is only 165 blocks long. So it's a similar problem here - both the free space trees are internally consistent, the inode BMBT is internally consistent, but the space that they track is not consistent. After repair: 63:[92551,292] 64:[92856,2] -> correctly accounted .... 169:[97415,49] 170:[97468,56] 171:[97528,168] -> used space [97464,2], [97524,4] But that's a very different freespace map around the second extent in the EFI. It's most definitely not a contiguous range of 1920 blocks now that repair has made sure the inode has no extents and the range is correctly accounted for, so that indicates that the length in the EFI is suspect. Maybe it should only be 7 blocks? Did you run the filesystem out of space again before this happened? If you don't hit enospc, does removing files trigger this corruption?

The objection was raised that there might be some file system out there that might depend on this behaviour. I can't imagine why, but I suppose it's at least theoretically possible. So the idea is that this particular patch is *guaranteed* not to make any difference. That way there can be no question about the patch'es correctness. I'm going to follow up with a patch for ext4 that does exactly that, but the idea is to allow each file system maintainer to do that for their own file system. I could do that as well for file systems that are "obviously" read-only, but then I'll find out that there's some wierd case where the file system can be used in a read-write fashion. (Example: UDF is normally used for DVD's, but at least in theory it can be used read/write --- I'm told that Windows supports read-write UDF file systems on USB sticks, and at least in theory it could be used as a inter-OS exchange format in situations where VFAT and exFAT might not be appropriate for various reasons.)

It's either: You only align XFS if you have an allocation heavy workload where the file sizes are smaller but very close to stripe width, or many times larger than stripe width. You *appear* to currently have a 3.84 MB stripe width. That is yet to be confirmed by you. > - 4 (four LUNs as far as my OS is concerned) My guess is that 2 of the 4 point to the same RAID10, both to the entire capacity, or to half the capacity.

If you are unable to figure out exactly how your RAIDs, VGs, and LUNs are configured, do not under any circumstances align XFS. All it will do is decrease performance.

If the file system is mounted read-write, and it is transitioning to read-only, i.e. "mount -o remount,ro /" then you do want to write out all dirty data before you transition it to be read-only (otherwise you would lose data). It is my belief that this is the _only_ data integrity issue which is implied by remount (and this is more about not losing work done by previous system calls). The background reason for this commit is that a user complained on the ext4 list that he is using containers in a virtualization environment, and due to the init scripts which the user doesn't want to change, it is causing gazillions of no-op remounts, and this is causing ext4 (and xfs) to do send CACHE FLUSH commands because it is required by the syncfs(2) system call, which also calls sync_filesystem. These CACHE FLUSH commands are unneeded for anything, especially for these no-op remounts, and so I want them to go away for remounts, but they should still be there in response to syncfs(2) requests.

Well, syncfs() in RO->RW transition clearly isn't needed. In RW->RO transition basically everybody needs it. What is disputable is the case of RW->RW remounts and I could imagine someone relying on syncfs() there although 99% of filesystems don't need it. So I agree in principle with moving the responsibility for syncfs() to ->remount so that each filesystem can decide. > So the idea is that this particular patch is *guaranteed* not to make > any difference.

Yes, some people do use UDF for USB sticks - Linux supports it in read-write mode as well (although with somewhat limited set of features). But the filesystem's I've named are those which clearly either bail with error if RW mount is attempted or silently change it to RO mount. In these cases, I'd just patch away the unnecessary sync_fs().

The filesystem seems to be clean now, after two xfs_repairs with an intervening recurrence of the issue during another rm -f *. It certainly seems possible that the first xfs_repair only partially fixed the corruption, and the second occurrence of the issue wasn't a real reproduction but fallout from an incomplete fix. Unfortunately I didn't think to snapshot the LUN before fixing it up, so I can't go back and try.

I did not run the filesystem out of space again. I'd actually deactivated most of the Oracle tracing and started another benchmark run, then noticed that the filesystem was still about 40% full (presumably my last rm -f * only got that far before encountering the error), so I did another rm -f * in the trace file directory and hit the issue again. As time is available, I will see if I can reproduce the issue in the manner I produced it initially and report back if so. I believe xfs_repair is now running clean; latest output is here if you want to confirm: https://dl.dropboxusercontent.com/u/31522929/xfs_repair-latest-output-2014-= 03-13-2 Also I've upgraded to the latest xfs_repair built on main from git://oss.sgi.com/xfs/cmds/xfsprogs; git log shows commit ea4a8de1e1 which Ben recommended (though xfs_repair -V still shows version 3.2.0-alpha2).

It is possible that the EFI can be pushed to the AIL before a forced shutdown where it gets stuck for following reasons: No EFD. If freeing the extent fails in xfs_bmap_finish() or xfs_recover_process_efi(), then the corresponding extent free done (EFD) entry will not be created. EFD IOP Abort processing. If xfs_trans_cancel() is called with an abort flag, or if the xfs_trans_commit() is called when the file system is in forced shutdown or if the log buffer write fails, then the EFD iop commands will not remove the EFI from the AIL. If the EFI entry is left on the AIL, xfs_ail_push all_sync() will fail to complete, the unmount will hang, and a reboot is required to get the complete the unmount. A forced shutdown pushs the CIL, so the EFI/EFD on the CIL before the forced shutdown will be processed normally. Aborted EFI/EFD will remove themself. All that remains to be done to is to remove the EFI entries from the AIL in the above listed shutdown cases. Signed-off-by: Mark Tinguely --- Note to Christoph about the xfs_recover_process_efi part of patch: From b90935eaba9eb13c67101e5d723513bc6ca6e722 Mon Sep 17 00:00:00 2001 Date: Sat, 23 Nov 2013 20:11:09 +0100 Subject: [PATCH] xfs: simplify EFI/EFD recovery Use a cancellation table, similar to how we handle buffers instead of abusing the AIL during recovery. http://oss.sgi.com/archives/xfs/2013-12/msg00438.html will place the EFI onto the AIL in xfs_recover_process_efi() by the time the xfs_free_extent() error happens. Therefore the changes in xfs_recover_process_efis() would be the same with or without your new feature. Tested: Recovery - metadata with bad extent. xfs_bmap_finish() - placed errors as if the free extent call failed. - forced shutdown (as if from a different thread) before EFD created. - forced shutdown (as if from a different thread) after EFD created but before xfs_trans_commit() - forced shutdown after xfs_trans_commit() - xfstests ... fs/xfs/xfs_bmap_util.c | 9 +++++-- fs/xfs/xfs_extfree_item.c | 55 ++++++++++++++++++++++++++++++++++++++++++---- fs/xfs/xfs_extfree_item.h | 1 fs/xfs/xfs_log_recover.c | 27 ++++++++++------------ 4 files changed, 71 insertions(+), 21 deletions(-) Index: b/fs/xfs/xfs_bmap_util.c =================================================================== --- a/fs/xfs/xfs_bmap_util.c +++ b/fs/xfs/xfs_bmap_util.c @@ -124,8 +124,12 @@ xfs_bmap_finish( free->xbfi_blockcount))) { /* * The bmap free list will be cleaned up at a - * higher level.

Copying that file (with cp -a) yields a copy that doesn't trigger that behaviour. What's more, xfs_repair doesn't notice anything fishy with that sucker. This had been introduced (or, more likely, exposed) by the commit in question. As far as I can see, it's an on-disk corruption of some sort; it *might* be triggered by some kind of dio-related race, but I would be rather surprised if that had been the case - fsx is single-threaded, after all, and making it fsync() *and* mmap/msync/munmap after each write still produces such a file. The file contents per se is fine, it's the page tail on mmap() that is bogus. Filesystem image after that crap is on ftp.linux.org.uk/pub/people/viro/img.bz2; with that image mounted on /mnt we have ; ls -l /mnt/junk -rw-r--r-- 1 root root 444928 Mar 15 16:26 /mnt/junk ; echo $((0x6ca00)) 444928 ; cat >foo.c <<'EOF' #include #include main(int argc, char **argv) { int fd = open(argv[1], 0); char *p = (char *)mmap(0, 0xa00, PROT_READ, MAP_SHARED, fd, (off_t)0x6c000); if (p != (char *)-1) write(1, p + 0xa00, 4096 - 0xa00); } EOF ; gcc foo.c ; ./a.out /mnt/junk | od -c ; cp -a /mnt/junk /mnt/junk1 ; ./a.out /mnt/junk1 | od -c 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0003000 And that's essentially what makes generic/263 complain. Note, BTW, that fallocate and hole-punching is irrelevant - test in generic/263 steps into those, but the same thing happens with these operations disabled (by -F -H). I've found the thread from last June where you've mentioned generic/263 regression; AFAICS, Dave's comments there had been wrong...

BTW, experimenting with that thing shows that junk in the tail of the page actually comes from some unused sectors on the same device. So it's an information leak at the very least - I have seen it pick bits and pieces of previously removed files that way. While we are at it, the following creates such a buggered file in about a half of runs: #include #include #include #include #include #include #define O_DIRECT 00040000 main() { int n = 0x5cf2e - 0x47000; int fd = open("/mnt/junk", O_RDWR|O_CREAT|O_TRUNC|O_DIRECT, 0666); char *p; ftruncate(fd, 0x5cf2e); p = mmap(NULL, n, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x47000); memset(p, 'x', n); msync(p, n, MS_SYNC); munmap(p, n); lseek(fd, 0x59000, SEEK_SET); p = malloc(0x13a00 + 512); memset(p, 'z', 0x13a00 + 512); write(fd, p + 512 - ((unsigned long)p & 511), 0x13a00); } The frequency depends on the fraction of unused sectors with non-zero contents - for all I know it might hit that bug in 100% of runs, but I can only detect that if the junk it picks contains non-zero data.

So we have an empty file extended by ftruncate(), then mmap+msync+munmap in its tail, then O_DIRECT write starting from a couple of blocks prior to EOF and extending it by ~15 blocks. New EOF is 2.5Kb off the beginning of the (new) last block. Then it's closed. Remaining 1.5Kb of that last block is _not_ zeroed out; moreover, pagefault on that page ends up reading the entire block, the junk in the tail not getting zeroed out in in-core copy either. Interesting...

Interesting... AFAICS, what happens is that we hit this /* * If this is O_DIRECT or the mpage code calling tell them how large * the mapping is, so that we can avoid repeated get_blocks calls. */ if (direct || size > (1 << inode->i_blkbits)) { xfs_off_t mapping_size; mapping_size = imap.br_startoff + imap.br_blockcount - iblock; mapping_size <<= inode->i_blkbits; ASSERT(mapping_size > 0); if (mapping_size > size) mapping_size = size; if (mapping_size > LONG_MAX) mapping_size = LONG_MAX; bh_result->b_size = mapping_size; } and while the caller (do_direct_IO()) is quite happy to skip subsequent calls of get_block, buffer_new() is *NOT* set by that one. Fair enough, since the _first_ block of that run (the one we'd called __xfs_get_blocks() for) isn't new, but dio_zero_block() for the partial block in the end of the area gets confused by that. Basically, with direct-io.c as it is, get_block may report more than one block if they are contiguous on disk *AND* are all old or all new. Returning several old blocks + several freshly allocated is broken, and "preallocated" is the same as "freshly allocated" in that respect - they need to be zeroed. Looks like __xfs_get_blocks() is broken in that respect - I'm definitely seeing O_DIRECT write() crossing the EOF calling it *once*, getting ->b_size set to a lot more than what remains until EOF and buffer_head not getting BH_New on it. And once that has happened, we are SOL - the tail of the last block isn't zeroed. Increase of prealloc size made that more likely to happen (unsurprisingly, since it can only happen when blocks adjacent to the last block of file are not taken by anything else).

Yes, we've known about this since 2011. Right - that's a long standing problem, and one I've never been able to isolate and so reproduce with any luck. It can only be reproduced when you use mmap and direct IO on the same file, and every time I've added debug to find out where the tail block corruption was being introduced, the data corruption goes away.

That page is filled by mpage_readpages(), not XFS.

Indeed, create the partial tail block with truncate: $ rm /mnt/test/foo $ xfs_io -f -c "truncate 0x6ca00" /mnt/test/foo $ sudo umount /mnt/test $ sudo mount /dev/vdb /mnt/test $ ls -l /mnt/test/foo -rw------- 1 root root 444928 Mar 17 09:45 /mnt/test/foo $ ./mmap-eof-test /mnt/test/foo |od -c 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0003000 $ With buffered IO: $ rm /mnt/test/foo $ xfs_io -f -c "pwrite 0x6c9ff 1" -c fsync /mnt/test/foo wrote 1/1 bytes at offset 444927 1.000000 bytes, 1 ops; 0.0000 sec (75.120 KiB/sec and 76923.0769 ops/sec) $ sudo umount /mnt/test $ sudo mount /dev/vdb /mnt/test $ ls -l /mnt/test/foo -rw------- 1 root root 444928 Mar 17 10:23 /mnt/test/foo $ ./mmap-eof-test /mnt/test/foo |od -c 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0003000 Or with direct IO: $ rm /mnt/test/foo $ xfs_io -fd -c "pwrite 0x6c800 0x200" /mnt/test/foo wrote 512/512 bytes at offset 444416 512.000000 bytes, 1 ops; 0.0000 sec (410.509 KiB/sec and 821.0181 ops/sec) $ sudo umount /mnt/test $ sudo mount /dev/vdb /mnt/test $ ls -l /mnt/test/foo -rw------- 1 root root 444928 Mar 17 10:25 /mnt/test/foo $ ./mmap-eof-test /mnt/test/foo |od -c write returned 1536/0 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0003000 And you don't see a failure from your test program because the partial tail block is correctly zeroed on disk. So there's something else going on here - the write paths XFS do zero the tail of the block on disk, and so mmap should not *ever* exposing stale data. AFAICT, the only way we can get garbage beyond EOF is to have application mmap() map the page covering EOF, write beyond EOF, then have it written back. However, we actually handle that case in xfs_vm_writepage() by calling zero_user_segment() on the range of the page beyond EOF. So we can't get garbage written beyond EOF that way, either. So I've got no real idea of how we are getting garbage on disk, what role DIO plays in it, or even how to reproduce it reliably in a manner that doesn't result in instrumentation causing the data corruption to magically disappearing... > ; cp -a /mnt/junk /mnt/junk1 > ; ./a.out /mnt/junk1 | od -c > 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 > * > 0003000 cp is showing the correct data because the __block_write_begin() path zeroes the bytes beyond EOF in the tail page - it doesn't copy them from the source.... > And that's essentially what makes generic/263 complain. Yup, but it is merely the messenger.... > I've found the thread from last June where you've mentioned generic/263 > regression; AFAICS, Dave's comments there had been wrong... generic/263 has failed since it was first split out of generic/091 in commit 0d69e10ed15b01397e8c6fd7833fa3c2970ec024 back in 2011. We discovered this problem by accident when we busted fsx option parsing and it ran the wrong options resulting in a mmap+dio being run. We fixed that up and added the workload to generic/091 (commit c00bad1c4c348e45d00982d06fc40522fb8cb035), then split it to a separate test to isolate the failure case and leave generic/091 as a reliable regression test.

It behaves just like a race condition.... See downthread. And I would be *very* surprised if it was a race - don't forget the msync() done before that write(). I think I know what's going on - O_DIRECT write starting a bit before EOF on a file with the last extent that can be grown. It fills a buffer_head with b_size extending quite a bit past the EOF; the blocks are really allocated. What causes the problem is that we have the flags set for the *first* block. IOW, buffer_new(bh) is false - the first block has already been allocated. And for direct-io.c it means "no zeroing the tail of the last block".

BTW, that's something I have directly observed - xfs_get_blocks_direct() called with iblock corresponding to a bit under 16Kb below EOF and returning with ->b_size equal to 700K and ->b_flags not containing BH_New. Once that has happened, the rest is inevitable - do_direct_IO() will shove the userland data (~80Kb) into the blocks starting from one in ->b_blocknr and dio_zero_block() called after it will do nothing, since as far as it knows these blocks were not new - BH_New isn't there. We may or may not get a visible junk (after all, the block tail might have contained zeros), but the situation above is easily reproduced and when it happens, there will be no zeroing out. Actually, I'm not sure if the comment in direct-io.c (just before get_more_blocks()) is correct; it says * If the fs has mapped a lot of blocks, it should populate bh->b_size to * indicate how much contiguous disk space has been made available at * bh->b_blocknr. * * If *any* of the mapped blocks are new, then the fs must set buffer_new(). * This isn't very efficient... but that is unsafe - consider a situation when you are writing 20Kb from e.g. 0.5Kb offset from the beginning of last (4Kb) block. You have 6 blocks affected, right? One old, five new. And you want the last half-kilobyte of the new last block zeroed out. What you do _not_ want is zeroing out the half-kilobyte just before the affected area - the data there should stay. IOW, we really can't mix new and old blocks in that interface - not enough information is passed back to caller to be able to decide what does and what does not need zeroing out. It should be either all-new or all-old. And it's not just the EOF, of course - the beginning of a hole in a sparse file isn't any different from the end of file in that respect.

It's not obvious from your description what the issue is here.

And buffer_new() is set on both of the allocation ranges that are mapped, and the tail block has zeroes written into it correctly the the mmap read gives zeroes in teh region beyond EOF.

XFS should never do that. It does not mix existing block mappings with newly allocated mappings, and so the newly allocated region beyond EOF should always give a "xfs_get_blocks_alloc" trace, and when that is emitted we always set buffer_new().... > And once that has happened, we are SOL - the > tail of the last block isn't zeroed.

Right, but I still don't see what userspace IO pattern is triggering this block mapping weirdness. A script that replicates it without involving mmap() at all would be nice...

It should be either all-new or all-old. Right, and XFS should not be mixing old and new in the way you are describing, and that's what I can't reproduce. See my reply on the other thread. Probably best to continue there... > And it's not just the EOF, of course - the beginning of a hole in a sparse > file isn't any different from the end of file in that respect. Except that XFS treats that differently - it does allocation as unwritten extents there, and any mapping that covers an unwritten block will always result in buffer_new() getting set...

So, here's the precondition: $ rm -rf /mnt/test/blah $ xfs_io -f -c "pwrite 0 32k" /mnt/test/blah $ xfs_io -f -c "pwrite -b 64k 0 240k" /mnt/test/blah The first write sets the I_DIRTY_RELEASE flag on close, then second sees that flag and does not remove the delayed allocation beyond EOF on the second close. So now there's a delalloc extent out to roughly 450k (block 112). Then run the above test case, and the msync causes writeback to occur and hence that turns the entire delalloc extent into allocated blocks - a single extent that extends beyond EOF. > > Looks like __xfs_get_blocks() is broken in that respect - I'm definitely > > seeing O_DIRECT write() crossing the EOF calling it *once*, getting > > ->b_size set to a lot more than what remains until EOF and buffer_head > > not getting BH_New on it. > > XFS should never do that.

And so XFS is not mixing extent types, nor is it seeing newly allocated blocks beyond EOF, and so it sees it as a single extent full of valid data.... OK, now I understand where the bad mapping problem is coming from, and why a changing in speculative prealloc size might be seen as the "cause" by a bisect. And it is a pre-existing condition that has been there for years - I'd think that testing with allocsize= would expose it easily on old kernels. Al, you're right that the code that calculates the mapping size needs to split mappings that extend across EOF for direct IO. I'll cook up a patch to fix it after lunch. Thanks for digging in to this and finding what I couldn't.

You don't handle the xfs_bmap_finish() case properly - the patch only addresses the case where the EFD was created and contains a reference to the EFI. The only time we can have an EFI in the AIL without an EFD pointing to it is if xfs_trans_reserve() call in xfs_bmap_finish() fails due to a shutdown. That failure case leaks the EFI reference that is supposed to be passed to the EFD... > EFD IOP Abort processing.

Which they should, because after xfs_trans_get_efd(), the EFD owns the reference to the EFI. Hence aborting the EFD should release the EFI reference it owns. > Index: b/fs/xfs/xfs_extfree_item.c > =================================================================== > --- a/fs/xfs/xfs_extfree_item.c > +++ b/fs/xfs/xfs_extfree_item.c > @@ -420,8 +420,15 @@ STATIC void > xfs_efd_item_unlock( > struct xfs_log_item *lip) > { > - if (lip->li_flags & XFS_LI_ABORTED) > + /* > + * Clear the EFI if on AIL when aborting xfs_bmap_finish. > + * The forced shutdown will force the log, so other EFDs > + * should not be processed from the CIL. > + */ > + if (lip->li_flags & XFS_LI_ABORTED) { > + xfs_efi_clear_ail(lip->li_ailp); > xfs_efd_item_free(EFD_ITEM(lip)); > + } > } So, we abort one EFI, so we kill every EFI in the filesystem? We want to be able to cancel and rollback transactions eventually, and this will prevent us from being able to do that as it will kill EFIs unrelated to the EFD being aborted. AFAICT, all this needs to do is: if (!(lip->li_flags & XFS_LI_ABORTED)) return; xfs_efi_release(efdp->efd_efip, efdp->efd_format.efd_nextents); xfs_efd_item_free(efdp); i.e. before freeing the EFD, release the reference to the EFI that it was passed. > @@ -439,10 +446,15 @@ xfs_efd_item_committed( > struct xfs_efd_log_item *efdp = EFD_ITEM(lip); > > /* > - * If we got a log I/O error, it's always the case that the LR with the > - * EFI got unpinned and freed before the EFD got aborted. > + * If we got a log I/O error and the EFI is also in this buffer, it > + * will be unpinned and freed before the EFD got aborted.

And if we do the right thing with the EFI reference count when aborting the EFI (i.e. call __xfs_efi_release() rather than freeing it) the aborting of transactions will correctly free all the references to the EFI and remove them from the AIL. The only case we then have to handle specially is the xfs_trans_reserve failure in xfs_bmap_finish(), where we need to release the EFI directly in the error path. That gets rid of the "big hammer" error handling for normal runtime shutdown that xfs_efi_clear_ail(). i.e. we need to fix the reference count handling, not work around it. > Index: b/fs/xfs/xfs_log_recover.c > =================================================================== > --- a/fs/xfs/xfs_log_recover.c > +++ b/fs/xfs/xfs_log_recover.c > @@ -3634,20 +3634,23 @@ xlog_recover_process_data( > /* > * Process an extent free intent item that was recovered from > * the log.

I think we should simply remove the XFS_EFI_RECOVERED bit from the reference counting code, and simply subtract one of the EFI references in xlog_recover_efi_pass2() where we insert the EFI into the AIL, so that it behaves exactly like the runtime case when later processing the EFDs. That is, in xlog_recover_efd_pass2() when we find a matching EFD we simply call xfs_efi_release() and that does all the freeing because we're removing the EFD reference which is the only remaining reference. Then in xlog_recover_process_efi(), we simply call xfs_efi_release() for the error cases to drop the last reference to the EFI, otherwise the commit of the EFD will free it because it calls xfs_efi_release() appropriately. > > @@ -3718,8 +3714,8 @@ STATIC int > xlog_recover_process_efis( > struct xlog *log) > { > - xfs_log_item_t *lip; > - xfs_efi_log_item_t *efip; > + struct xfs_log_item *lip; > + struct xfs_efi_log_item *efip; > int error = 0; > struct xfs_ail_cursor cur; > struct xfs_ail *ailp; > @@ -3753,12 +3749,13 @@ xlog_recover_process_efis( > error = xlog_recover_process_efi(log->l_mp, efip); > spin_lock(&ailp->xa_lock); > if (error) > - goto out; > + break; > lip = xfs_trans_ail_cursor_next(ailp, &cur); > } > -out: > xfs_trans_ail_cursor_done(ailp, &cur); > spin_unlock(&ailp->xa_lock); > + if (error) > + xfs_efi_clear_ail(ailp); > return error; > } If we fix the reference counting, then I think all we need here is: int error = 0; while (ail cursor next) { .... if (!error) error = xlog_recover_process_efi() else xfs_efi_release(efip) .... } So that any error will trigger freeing of all the other unprocessed EFIs on the AIL that are pending recovery without needing any more special looping....

The elevator is per physical device. For SSD use noop. But with your setup is doesn't matter as md/RAID will run at rust speed. A better solution is to remove the SSD partition from the md/RAID array, reshape/shrink/rebuild the array to make it happy, whatever is necessary after removing the SSD partition. Now configure the SSD partition as bcache and enable writeback policy. This will increase the performance of the rust array to SSD level for writes, and for reads after frequently accessed data is cached in your SSD. -- Stan From eller.gamer.derek329@gmail.com Mon Mar 17 18:22:41 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.3 required=5.0 tests=FREEMAIL_ENVFROM_END_DIGIT, FREEMAIL_FROM,HTML_MESSAGE,T_DKIM_INVALID autolearn=no version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id 7FEF17F51 for ; Mon, 17 Mar 2014 18:22:41 -0500 (CDT) Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by relay2.corp.sgi.com (Postfix) with ESMTP id 6F8B0304043 for ; Mon, 17 Mar 2014 16:22:38 -0700 (PDT) X-ASG-Debug-ID: 1395098556-04cb6c567663a790001-NocioJ Received: from mail-ig0-f195.google.com (mail-ig0-f195.google.com [209.85.213.195]) by cuda.sgi.com with ESMTP id wx2gZTpvcXsmkeip (version=TLSv1 cipher=RC4-SHA bits=128 verify=NO) for ; Mon, 17 Mar 2014 16:22:36 -0700 (PDT) X-Barracuda-Envelope-From: eller.gamer.derek329@gmail.com X-Barracuda-Apparent-Source-IP: 209.85.213.195 X-Barracuda-IPDD: Level1 [gmail.com/209.85.213.195] Received: by mail-ig0-f195.google.com with SMTP id uq10so1223392igb.2 for ; Mon, 17 Mar 2014 16:22:36 -0700 (PDT) X-Barracuda-IPDD: Level1 [gmail.com/209.85.213.195] X-Barracuda-IPDD: Level1 [gmail.com/209.85.213.195] DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:date:message-id:subject:from:to:content-type; bh=5zQ0nQbGWglPg5l+7toCmkqPZg2o+z3wMghyUAz6Wq4=; b=JSKlfgxUHR5IXEHhp6dCNpgbVsTvK0edVMwH3Ct5sy7SMbgEmeIif6U87O8jbuXCN7 xc2Q0Ah28nO1gtGzkgclnU8RpxV4e0Yj7asCBtEIEpfbpqkqidyzJrdaqUTURWNahZo9 dqKJMIqduSoctWQAZcBPQOhtnV/rzepj6TmoR4ET7pk62opeyk9lOLXqB08hCayKhVPw 8lqgnq4kARiN4Ceo242lQIJWZIVD5/s/eznbBLyYMPa5o+iP0CxCHC2pYiUDBrD/yJBv WCrpg9cU1RlGG4nDOfx0txCpcSRN0rO1YSFNY6OMCkUZVFGv4tGZXuaSt0Y4UsHWZ1cX r1jA== MIME-Version: 1.0 X-Received: by 10.42.228.131 with SMTP id je3mr3093323icb.59.1395091886985; Mon, 17 Mar 2014 14:31:26 -0700 (PDT) Received: by 10.64.239.201 with HTTP; Mon, 17 Mar 2014 14:31:26 -0700 (PDT) Date: Mon, 17 Mar 2014 17:31:26 -0400 Message-ID: Subject: How to Collect Your First 1,000 Emails From: Derek Eller X-ASG-Orig-Subj: How to Collect Your First 1,000 Emails To: undisclosed-recipients:; Content-Type: multipart/alternative; boundary=001a1133d4585a6f3604f4d424ce X-Barracuda-Connect: mail-ig0-f195.google.com[209.85.213.195] X-Barracuda-Start-Time: 1395098556 X-Barracuda-Encrypted: RC4-SHA X-Barracuda-URL: http://192.48.176.15:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=DKIM_SIGNED, DKIM_VERIFIED, HTML_MESSAGE X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.4007 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- -0.00 DKIM_VERIFIED Domain Keys Identified Mail: signature passes verification 0.00 DKIM_SIGNED Domain Keys Identified Mail: message has a signature 0.00 HTML_MESSAGE BODY: HTML included in message --001a1133d4585a6f3604f4d424ce Content-Type: text/plain; charset=ISO-8859-1 There is absolutely no better platform that provides exactly what you need to know...

Except that this now leaves stale, unreferenced delalloc extents on the inode, so there's some other problem being masked by this behaviour and so generic/270 now assert fails.

based on xfs/242. This is very similar to ext4/001 however this test has some tweaks to make it work test zero range on generic file system. This includes turning off ext4 extents zeroout and disabling the test for xfs on systems where PAGE_SIZE > 4096. It is testing extent tree manipulation with fallocate zero range operation.

This doesn't give you any extra parallelism at all over just creating $free_inode files in a single directory with a single thread. Indeed, it will probably be slower due to the contention on the directory mutex. If you want to scale this in terms of parallelism to keep the creation time down, each loop needs to write into a different directory. i.e. something like: echo "Create $((loop * 1000)) files in $SCRATCH_MNT/testdir" >>$seqres.full while [ $i -lt $loop ]; do mkdir -p $SCRATCH_MNT/testdir/$i create_file $SCRATCH_MNT/testdir/$i 1000 $i >>$seqres.full 2>&1 & let i=$i+1 done wait And even then I'd suggest that you'd be much better off with 10,000 files to a sub-directory.... > +# log inode status in $seqres.full for debug purpose > +echo "Inode status after taking all inodes" >>$seqres.full > +df -i $SCRATCH_MNT >>$seqres.full > + > +_check_scratch_fs > + > +# Check again after removing all the files > +rm -rf $SCRATCH_MNT/testdir That can be parallelised as well when you have multiple subdirs: for d in $SCRATCH_MNT/testdir/*; do rm -rf $d & done wait Cheers, Dave. -- Dave Chinner david@fromorbit.com From sandeen@sandeen.net Wed Mar 19 19:22:49 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay3.corp.sgi.com [198.149.34.15]) by oss.sgi.com (Postfix) with ESMTP id 430A57F6D for ; Wed, 19 Mar 2014 19:22:49 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay3.corp.sgi.com (Postfix) with ESMTP id CE6D3AC007 for ; Wed, 19 Mar 2014 17:22:45 -0700 (PDT) X-ASG-Debug-ID: 1395274963-04cbb054b64d8610001-NocioJ Received: from sandeen.net (sandeen.net [63.231.237.45]) by cuda.sgi.com with ESMTP id W7T84UlNXF6Frn1r for ; Wed, 19 Mar 2014 17:22:43 -0700 (PDT) X-Barracuda-Envelope-From: sandeen@sandeen.net X-Barracuda-Apparent-Source-IP: 63.231.237.45 Received: from liberator.sandeen.net (liberator.sandeen.net [10.0.0.4]) (using TLSv1 with cipher DHE-RSA-AES128-SHA (128/128 bits)) (No client certificate requested) by sandeen.net (Postfix) with ESMTPSA id 61082602D745; Wed, 19 Mar 2014 19:22:43 -0500 (CDT) Message-ID: <532A34D3.8060805@sandeen.net> Date: Wed, 19 Mar 2014 19:22:43 -0500 From: Eric Sandeen User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:24.0) Gecko/20100101 Thunderbird/24.4.0 MIME-Version: 1.0 To: Eryu Guan , xfs@oss.sgi.com Subject: Re: [PATCH] shared: new test to use up free inodes References: <1395221269-11085-1-git-send-email-eguan@redhat.com> X-ASG-Orig-Subj: Re: [PATCH] shared: new test to use up free inodes In-Reply-To: <1395221269-11085-1-git-send-email-eguan@redhat.com> X-Enigmail-Version: 1.6 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[63.231.237.45] X-Barracuda-Start-Time: 1395274963 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.60 X-Barracuda-Spam-Status: No, SCORE=0.60 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=MARKETING_SUBJECT X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.4076 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.60 MARKETING_SUBJECT Subject contains popular marketing words On 3/19/14, 4:27 AM, Eryu Guan wrote: > Stress test fs by using up all inodes and check fs. > > Also a regression test for xfsprogs commit > d586858 xfs_repair: fix sibling pointer tests in verify_dir2_path() Thanks Eryu. I had started to write this test but ran into another bug (where xfs blows past the maximum inode space %) so got distracted. I see Dave's already picked apart the patch so I won't comment specifically on it, but you might be aware of the possibility that xfs won't stop when we hit the default imaxpct, and may actually fill the entire fs. That's not necessarily a problem but it may take longer than you expect. I also wonder what's necessary to actually test the sibling pointer problem; on xfs, it's probably just a sufficiently large directory, not necessarily a full fs? -Eric > Signed-off-by: Eryu Guan > --- > tests/shared/006 | 96 ++++++++++++++++++++++++++++++++++++++++++++++++++++ > tests/shared/006.out | 2 ++ > tests/shared/group | 1 + > 3 files changed, 99 insertions(+) > create mode 100755 tests/shared/006 > create mode 100644 tests/shared/006.out > > diff --git a/tests/shared/006 b/tests/shared/006 > new file mode 100755 > index 0000000..a3b13b6 > --- /dev/null > +++ b/tests/shared/006 > @@ -0,0 +1,96 @@ > +#! /bin/bash > +# FS QA Test No. shared/006 > +# > +# Stress test fs by using up all inodes and check fs. > +# > +# Also a regression test for xfsprogs commit > +# d586858 xfs_repair: fix sibling pointer tests in verify_dir2_path() > +# > +#----------------------------------------------------------------------- > +# Copyright (c) 2014 Red Hat Inc.

That's > not necessarily a problem but it may take longer than you expect. Yes, I noticed that testing on xfs didn't give ENOSPC error as testing on ext4 do. The number of extra files created is less than 1000, so I think that's fine. > > I also wonder what's necessary to actually test the sibling pointer problem; > on xfs, it's probably just a sufficiently large directory, not necessarily > a full fs? I've seen list corruption and then xfs force shutdown by running the same test(at the time removing all created files) on earlier RHEL7 test kernels, then the bug was fixed by xfs update. So I'm not sure it's large directory or taking all free inode trigger the bug, I think I'd better still to fulfill the fs.

This is fine if the EFI made it to the AIL before the log abort - which it may or may not have done. Log errors will not force the log. The call to xfs_trans_committed_bulk() with the abort flag set will not place the EFI on the AIL (takes the iop_unpin/continue path). Your proposal of changing xfs_efi_committed() from freeing the EFI to a call to __xfs_efi_release() and changing xfs_efd_committed() to xfs_efi_release() will do the right thing for the counters and removing both the EFI/EFD entries, but it will also want to remove the non-existent EFI entry from the AIL.

Instead, we want the reference count that was intended for the AIL to be dropped when we abort the object so that we can free the object when the last reference count goes away. > Your proposal of changing xfs_efi_committed() from freeing the EFI > to a call to __xfs_efi_release() and changing xfs_efd_committed() to > xfs_efi_release() will do the right thing for the counters and > removing both the EFI/EFD entries, but it will also want to remove > the non-existent EFI entry from the AIL. I do not like adding the > EFI to the AIL in the abort path. If the EFI is not in the AIL, then don't try to remove it from the AIL. We do this for all sorts of objects on abort/shutdown. e.g. the abort path in xfs_buf_item_unlock() checks if the item is in the AIL before removing it. We do the same when flushing a dquot and a shutdown is encountered.

The page will eventually be released due to some other operation (e.g. direct IO), and it will not pass through invalidation because it is dirty. Hence it will be released with buffer_delay set on it, and trigger warnings in xfs_vm_releasepage() and assert fail in xfs_file_aio_write_direct because invalidation failed and we didn't write the corect amount. This causes failures on block size < page size filesystems in fsx and fsstress workloads run by xfstests. Fix it by completely trashing any state on the buffer that could be used to imply that it contains valid data when the delalloc range over the buffer is punched out during the failed write handling.

This doesn't take into account the fact that we may have already made successful writes to the same page (in the case of block size < page size) and hence we can truncate the page cache away from blocks with valid data in them. If these blocks are delayed allocation blocks, we now have a mismatch between the page cache and the extent tree, and this will trigger - at minimum - a delayed block count mismatch assert when the inode is evicted from the cache. We can also trip over it when block mapping for direct IO - this is the most common symptom seen from fsx and fsstress when run from xfstests. Fix it by only truncating away the exact range we are updating state for in this write_begin call.

If is caused by xfs_get_blocks() mapping a single extent that spans EOF without marking it as buffer-new() so that the direct Io code does not zero the tail of the block at the new EOF. This is a long standing bug that has been around for many, many years. Because xfs_get_blocks() starts the map before EOF, it can't set buffer_new(), because that causes he direct Io code to also zero unaligned sectors at the head of the IO. This would overwrite valid data with zeros, and hence we cannot validly return a single extent that spans EOF to direct IO. Fix this by detecting a mapping that spans EOF and truncate it down to EOF. This results in the the direct IO code doing the right thing for unaligned data blocks before EOF, and then returning to get another mapping for the region beyond EOF which XFS treats correctly by setting buffer_new() on it. This makes direct Io behave correctly w.r.t. tail block zeroing beyond EOF, and fsx is happy about that. Again, thanks to Al Viro for finding what I couldn't.

The fix for that is patch 6 of this series, but, well, there are a bunch of other problems that need to be fixed before making that change. Basically, the direct Io block mapping behaviour was covering up a bunch of other bugs in the delayed allocation extent/page cache state coherency mappings. Essentially, we punch out the page cache in quite a few places without first cleaning up delayed allocation extents over that range and that exposes all sorts of nasty issues once the direct IO mapping changes are made. All of these are existing problems, most of them are very unlikely to be seen in the wild. This patch set passes xfstests on a 4k block size/4k page size config with out problems. However, there is still a fsx failure in generic/127 on 1k block size/4k page size configurations that I haven't yet tracked down. That test was failing occasionally before this patch set as well, so it may be a completely unrelated problem. The sad fact of this patchset is it is mostly playing whack-a-mole with visible symptoms of bugs. It drives home the fact that bufferheads and the keeping of internal filesystem state attached to the page cache simply isn't a verifiable architecture. After spending several days of doing nothing else but tracking down these inconsistencies i can only conclude that the code is complex, fragile and extremely difficult to verify that behaviour is correct. As such, I doubt that the fixes are entirely correct, so I'm left with using fsx and fsstress to tell me if I've broken anything. Eyeballs appreciated, as is test results. Cheers, Dave.

If we repeatedly punch holes in a large delalloc extent, that reservation will eventually run out and we'll assert fail in xfs_bunmapi() because the indirect block reservation for the delalloc extent is zero. This is caused by doing a large delalloc write, then zeroing multiple ranges of that write using fallocate to punch lots of holes in the delayed allocation range. To avoid this problem, if we split the reservation and require more indirect blocks for the two new extents than we had for the old reservation, steal the additional blocks from the hole we punched in the extent. In most cases we only need a single extra block, so even if we punch only single block holes we can still retain sufficient indirect block reservations to avoid problems. In doing this "stealing", we need to change where we account for the delalloc blocks being freed. The block count held on the inode does not take into account the indirect block reservation, so we still need to do that before we free the extent. However, the accounting ofr free space in the superblock need to be done after we've stolen the blocks fro the freed extent so that they are accounted for correctly.

This resulted either in sending a wrong path string to the send stream or entering an infinite loop when building it. This happened in the following scenarios: 1) A directory was made a child of another directory which has a lower inode number and has a pending move/rename operation. This made the incremental send code go into an infinite loop when building a path string; 2) A directory was made a child of another directory which has a higher inode number, but the new parent wasn't moved nor renamed. Instead some other ancestor higher in the hierarchy, with an higher inode number too, was moved/renamed too. This made the incremental send code go into an infinite loop when building a path string; 3) An orphan directory is created and at least one of its non-immediate descendent directories have a pending move/rename operation. This made an incremental send issue to the send stream an invalid path string that didn't account for the orphan ancestor directory. This issue is fixed by the following linux kernel btrfs patches: Btrfs: fix incremental send's decision to delay a dir move/rename Btrfs: part 2, fix incremental send's decision to delay a dir move/rename Btrfs: send, account for orphan directories when building path strings Signed-off-by: Filipe David Borba Manana --- V2: Added more tests.

I started with a single entry but split it into a couple Q's when it turned into TL;DR fodder. ;) The text is embedded below for review. Thoughts on the questions or content is appreciated. Also, once folks are Ok with this... how does one gain edit access to the wiki? Brian --- Q: Why do files on XFS use more data blocks than expected? A: The XFS speculative preallocation algorithm allocates extra blocks beyond end of file (EOF) to combat fragmentation under parallel sequential write workloads. This post-EOF block allocation is included in 'st_blocks' counts via stat() system calls and is accounted as globally allocated space by the filesystem. This is reported by various userspace utilities (stat, du, df, ls) and thus provides a common source of confusion for administrators. Post-EOF blocks are temporary in most situations and are usually reclaimed via several possible mechanisms in XFS. See the FAQ entry on speculative preallocation for details. Q: What is speculative preallocation? How can I manage it? A: XFS speculatively preallocates post-EOF blocks on file extending writes in anticipation of future extending writes. The size of a preallocation is dynamic and depends on the size of the previous extent in the file (starting from 0 again if the write extends past a hole). As files grow larger, so do the size of preallocations. Speculative preallocation is not enabled for files smaller than a minimum size (64k by default, but can vary depending on filesystem geometry and/or mount options). Preallocations are capped at a maximum of 8GB on 4k block filesystems. Preallocation is throttled automatically as the filesystem approaches low free space conditions or other allocation limits on a file (such as a quota). In most cases, speculative preallocation is automatically reclaimed when a file is closed. The preallocation may persist after file close if an open, write, close pattern is repeated on a file. In this scenario, post-EOF preallocation is trimmed once the inode is reclaimed from cache or the filesystem unmounted. Linux 3.8 (and later) includes a scanner to perform background trimming of files with lingering post-EOF preallocations. The scanner bypasses files that have been recently modified to not interfere with ongoing writes. A 5 minute scan interval is used by default and can be adjusted via the following file (value in seconds): /proc/sys/fs/xfs/speculative_prealloc_lifetime Although speculative preallocation can lead to reports of excess space usage, the preallocated space is not permanent unless explicitly made so via fallocate or a similar interface. Preallocated space can also be encoded permanently in situations where file size is extended beyond a range of post-EOF blocks (i.e., via truncate). Otherwise, preallocated blocks are reclaimed on file close, inode reclaim, unmount or in the background once file write activity subsides. Finally, the XFS block allocation algorithm can be configured to use a fixed allocation size with the 'allocsize=' mount option. Note that speculative preallocation does not occur when a fixed allocation size is set and thus increases the potential for fragmentation via parallel writes.

So there is no mechanism that would shirnk preallocations in case when free= =20 space is (almost or) gone on a fs? Case: apache causes xfs to preallocate=20 several GB for its /var/..../{access,error}_log (common problem here) and t= hen=20 free space ends on that fs causing problems for every app that writes to /v= ar.

I suppose we could include a simple example of that in the first Q. This isn't necessarily true in the case of sparse files. xfs_bmap prints the extent information for a file, so it should be possible to determine how much post-EOF space exists from looking at the extent that covers EOF.

FWIW, what I'd really like is for the FAQ to be converted to a asciidoc document in the xfs-documentation tree. The current FAQ has lots of stuff that could do with updating, but editing a wiki document that long in a browser is, well, painful.

I'd rewrite this slightly differently, saying that preallocation "may persist beyond the lifecycle of any given file descriptor." And then describe the reason for this - that certain application behaviours (like slowly growing files, or file servers) can cause fragmentation if we remove the preallocation on fd close. These behaviours are automatically detected, and result in "delayed removal" of the preallocation. Q: How can I speed up or avoid delayed removal of speculative preallocation? A.

This should say "dynamic resizing of speculative preallocation does not occur" rather than "speculative preallocation does not occur", because allocsize only determines the size of the speculative preallocation beyond EOF that is done - it doesn't turn it off...

Does it disable it? fallocate is permanent preallocation using unwritten extents. Speculative preallocation is an extension of delayed allocation that is done when extending the file and the EOF falls into a hole. If there is unwritten extents beyond EOF, speulative preallocation is not performed. > I see rather dramatic fragmentation of the systemd journal when it is > stored on XFS, and it calls posix_fallocate before writing data to the > file. There's your problem - systemd is preventing delayed allocation, and so it fragmenting the file itself with it's write pattern. Basically, that's a bug in systemd, and not something the filesystem can avoid because userspace is directly controlling block allocation.

Background space trimmer takes care of that. We could probably also trigger it on ENOSPC, but once you are already at ENOSPC it's too late.... > Case: apache causes xfs to preallocate > several GB for its /var/..../{access,error}_log (common problem here) and then > free space ends on that fs causing problems for every app that writes to /var. Your log files would have to already be GB in size for that your apache logs to preallocate that much. If your log files are that big, then /var needs to be much, much larger than what the speculative prealloc for a handful of files could easily exhaust.

Right, but it's something that the filesystem has no real control over. We've been asked to allocate blocks immediately by fallocate(), and so we get what we get....

You mean it calls fallocate before each write? That's not very useful behaviour and should be fixed. If it calls fallocate for the whole expeted file size (or large increments) it should not fragment the file, and if it does there's a bug we'd need to look into.

March 2014 Summary

If we had all been blessed with great foresight we would have been investing in U.S. property in late 2012 when prices were at their lowest. However although home prices have been on the up through 2013 they are still way south of the peak price days and there are still great deals to be had.

Investors will still hold the whip hand over traditional homebuyers simply because price and loan interest rates are making it more difficult for family home purchasing against a backdrop of slow wage rises. With the increases in home prices and increased loan interest rates we have looked again at the buy or rent argument and find no financial case to rent albeit there may be many other reasons why that is a lifestyle choice. With the influx of property investors came the concern of what happens when they depart.

It seems from recent evidence that it is unlikely that we will witness a mass exodus anytime soon and in fact more investors are likely to be entering the market and remain in for the long haul. As we know there are any number of industry reports and home price indices available to provide guidance, however in many cases that simply causes increased confusion. The array of approaches and methodologies are bound to produce different outcomes so we probably need to be content with trends across the range rather than clinging to the numbers produced which do vary widely.

Analysts agree on continuing home price growth

We have previously argued in this blog that with the plethora of home price reports available and the numerous methodology approaches adopted the outcomes are bound to be very different across the range. We therefore concluded that no single report necessarily reflects the actual state of play and that the value is not actually in the figures but in the trend line. However there is also worth in appreciating the reasons that different approaches have been adopted.

Zillow, the real estate research company, remains highly critical of the methodology adopted by the industry leading Case-Shiller. read more

Content-Transfer-Encoding: 7bit Hi, We have a problem with one of our systems which is using XFS but we are unable to find the problem. Recently we had two moments, Tuesday 4th of March and Friday the 21st of March, where we had to reboot the system to get it up and running again. What happens: - The programs handling files on the XFS disc stop working when creating, deleting or writing files. They do not error they are just waiting on the command to complete. - One of our programs, a java application, goes into very high cpu usage (50%) which normally is at 1%. This could be something in our java application but it happens at the moment handling files gets stuck. - A nice restart of the programs does not succeed as wel a kill -9 does not work. - Trying to reboot the servers in a normal fashion does not work. As it is a virtual machine we have to do a shutdown (unplug power) and start it up again to get it up and running. Following details I have for you: System OS: Ubuntu 12.04 LTS Kernel: 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Server: Virtual machine in a VMWare setup. Disc: 300GB direct attached LUN We have an exact clone of this system for our acceptance environment. In this environment we are unable to reproduce this problem/situation. Differences between the two days is that our services on 2014-03-21 were quit busy with a lot of file changes on the xfs disc and on 2014-03-04 the system was very quiet on the moment the kernel traces appear and the services get stuck. Any help is appreciated. Regards Michel Verbraak.

We have a problem with one of our systems which is using XFS but we are unable to find the problem. Recently we had two moments, Tuesday 4th of March and Friday the 21st of March, where we had to reboot the system to get it up and running again.

What happens:
- The programs handling files on the XFS disc stop working when creating, deleting or writing files. They do not error they are just waiting on the command to complete.
- One of our programs, a java application, goes into very high cpu usage (50%) which normally is at 1%. This could be something in our java application but it happens at the moment handling files gets stuck.
- A nice restart of the programs does not succeed as wel a kill -9 does not work.
- Trying to reboot the servers in a normal fashion does not work. As it is a virtual machine we have to do a shutdown (unplug power) and start it up again to get it up and running.

Following details I have for you:

System OS: Ubuntu 12.04 LTS
Kernel: 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Server: Virtual machine in a VMWare setup.
Disc: 300GB direct attached LUN

We have an exact clone of this system for our acceptance environment. In this environment we are unable to reproduce this problem/situation.

Differences between the two days is that our services on 2014-03-21 were quit busy with a lot of file changes on the xfs disc and on 2014-03-04 the system was very quiet on the moment the kernel traces appear and the services get stuck.

Any help is appreciated.

Regards Michel Verbraak.

Following we see in the syslog on both moments (2014-03-04 and 2014-03-21):

Hi,

We have a problem with one of our systems which is using XFS but we are
unable to find the problem. Recently we had two moments, Tuesday 4th of
March and Friday the 21st of March, where we had to reboot the system to
get it up and running again.

What happens:
- The programs handling files on the XFS disc stop working when
creating, deleting or writing files. They do not error they are just
waiting on the command to complete.
- One of our programs, a java application, goes into very high cpu usage
(50%) which normally is at 1%. This could be something in our java
application but it happens at the moment handling files gets stuck.
- A nice restart of the programs does not succeed as wel a kill -9 does
not work.
- Trying to reboot the servers in a normal fashion does not work. As it
is a virtual machine we have to do a shutdown (unplug power) and start
it up again to get it up and running.

Following details I have for you:

System OS: Ubuntu 12.04 LTS
Kernel: 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
Server: Virtual machine in a VMWare setup.
Disc: 300GB direct attached LUN

We have an exact clone of this system for our acceptance environment. In
this environment we are unable to reproduce this problem/situation.

Differences between the two days is that our services on 2014-03-21 were
quit busy with a lot of file changes on the xfs disc and on 2014-03-04
the system was very quiet on the moment the kernel traces appear and the
services get stuck.

Any help is appreciated.

Regards Michel Verbraak.


Could you set up kdump and take a core dump next time it hangs?
There is a couple suspicious items in the syslog entries

We have seen process block worker's writes from completing, so looking at what is running and scheduled would be interesting. So a vmcore would tell a lot. --Mark.

Yup, everything is stuck waiting for writeback to complete. can you reproduce this? does the IO subsystem go idle when this occurs? or is it running flat out?

Shutting down filesystem > [1552067.298385] XFS (dm-7): Please umount the filesystem and rectify the problem(s) This is very interesting. From your first occurrence of the problem, there are 3 groups of duplicate allocated blocks in AG14. Remove both duplicates and the XFS_WANT_CORRUPTED_GOTO is triggered. In the first group, inode 940954751 maps fsb 58817713 for a length of 1920 and most of these blocks are allocated elsewhere in small lengths. In the second group, inode 940954759 is maps fsb 58822053 for a length 39, and most of these blocks are allocated elsewhere. In the third group there are smaller (1, 2, 3, 10) blocks of overlaps. The last 2 blocks of this group are allocated to inode 941385832 and are also listed as being free in the cntbr/bnobt at the same time. To make things more interesting, there a several cases where the first inode of an inode chunk has a single block mapped and that block is a duplicate for another active inode chunk block. Example of this is inode 941083520 maps fsb 58817724, but that block is also the inode chunk for inodes starting at 941083584. The earlier found interesting duplicate is the user data block, fsb 58836692 in inode 941386494 that is also a directory block 11 in inode 940862056. The user block was written last which is now garbage for the directory. I don't know any more why we are duplicate mapping. --Mark.

We are not yet able to reproduce. But your added explanation might help us in reproducing. The production environment is very dynamic in when clients connect to the service and what kind of requests they do. The colleague handling the incident tried to get some info but because he was alarmed quit late he decided for the reboot instead to get our production qorking again. For the next time we are preparing some scripts to gather information which might tell more. If you have any suggestions on commands we can run when it happens again please let me know? Currently we are configuring kdump as suggested by Mark and some other queries against our own software. > Cheers, > > Dave. Some extra info: this system has been running for about 1 year without any problems. During this time it was never rebooted or restarted until the issue on the 4th. Only change could be in the usage of java service running on it by external clients. We are looking into this. Thank you for looking into it.

Hi,

We have a problem with one of our systems which is using XFS but we are
unable to find the problem. Recently we had two moments, Tuesday 4th of
March and Friday the 21st of March, where we had to reboot the system to
get it up and running again.

What happens:
- The programs handling files on the XFS disc stop working when
creating, deleting or writing files. They do not error they are just
waiting on the command to complete.
- One of our programs, a java application, goes into very high cpu usage
(50%) which normally is at 1%. This could be something in our java
application but it happens at the moment handling files gets stuck.
- A nice restart of the programs does not succeed as wel a kill -9 does
not work.
- Trying to reboot the servers in a normal fashion does not work. As it
is a virtual machine we have to do a shutdown (unplug power) and start
it up again to get it up and running.

......

Following details I have for you:

System OS: Ubuntu 12.04 LTS
Kernel: 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
Server: Virtual machine in a VMWare setup.
Disc: 300GB direct attached LUN

We have an exact clone of this system for our acceptance environment. In
this environment we are unable to reproduce this problem/situation.

Differences between the two days is that our services on 2014-03-21 were
quit busy with a lot of file changes on the xfs disc and on 2014-03-04
the system was very quiet on the moment the kernel traces appear and the
services get stuck.

Any help is appreciated.

Regards Michel Verbraak.

From this moment on the services are not working anymore. Complete stuck.

Yup, everything is stuck waiting for writeback to complete.

can you reproduce this? does the IO subsystem go idle when this
occurs? or is it running flat out?
We are not yet able to reproduce. But your added explanation might help us in reproducing. The production environment is very dynamic in when clients connect to the service and what kind of requests they do.

The colleague handling the incident tried to get some info but because he was alarmed quit late he decided for the reboot instead to get our production qorking again. For the next time we are preparing some scripts to gather information which might tell more.
If you have any suggestions on commands we can run when it happens again please let me know? Currently we are configuring kdump as suggested by Mark and some other queries against our own software.
Cheers,

Dave.
Some extra info: this system has been running for about 1 year without any problems. During this time it was never rebooted or restarted until the issue on the 4th. Only change could be in the usage of java service running on it by external clients. We are looking into this.

Thank you for looking into it.

Michel.

Hi,

We have a problem with one of our systems which is using XFS but we are
unable to find the problem. Recently we had two moments, Tuesday 4th of
March and Friday the 21st of March, where we had to reboot the system to
get it up and running again.

What happens:
- The programs handling files on the XFS disc stop working when
creating, deleting or writing files. They do not error they are just
waiting on the command to complete.
- One of our programs, a java application, goes into very high cpu usage
(50%) which normally is at 1%. This could be something in our java
application but it happens at the moment handling files gets stuck.
- A nice restart of the programs does not succeed as wel a kill -9 does
not work.
- Trying to reboot the servers in a normal fashion does not work. As it
is a virtual machine we have to do a shutdown (unplug power) and start
it up again to get it up and running.

......

Following details I have for you:

System OS: Ubuntu 12.04 LTS
Kernel: 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
Server: Virtual machine in a VMWare setup.
Disc: 300GB direct attached LUN

We have an exact clone of this system for our acceptance environment. In
this environment we are unable to reproduce this problem/situation.

Differences between the two days is that our services on 2014-03-21 were
quit busy with a lot of file changes on the xfs disc and on 2014-03-04
the system was very quiet on the moment the kernel traces appear and the
services get stuck.

Any help is appreciated.

Regards Michel Verbraak.

Also atomic_dec_and_test really just returns true/false - there should ne no need for the explicit == 1 in the conditional.

We check the d_ino/d_off sizes above use that as part of the logic to drop into this conversion loop, which suggests this alone should not be a problem. If I read this right, we'd still want the dp->d_ino != d_ino and similar for d_off checks here to determine whether we did in fact overflow one of those values..? One final thought on the style fixes... it might be nice to push the logical operators and whatnot to the end of the line rather than the start of the subsequent. If you feel like it of course. I don't want to be too picky about this code. ;) Brian > + /* Overflow.

Yeah I have a patch to do that as well; I wanted to separate the bugfix from the more invasive cleanup, though - and I wanted to get the fix out for review sooner.

I think the the delayed completion is always wrong from the submission path. The error path is just a special case of a completion happening before _xfs_buf_ioapply returns.

I'm not sure; I don't think it was the buf_rele inside xfs_buf_iorequest that freed it, I think it was specifically the error path afterwards - in my case, in xfs_trans_read_buf_map(): xfs_buf_ (bp); // xfs_buf_iorequest code below xfs_buf_hold(bp); atomic_set(&bp->b_io_remaining, 1); _xfs_buf_ioapply(bp); <-- gets error if (atomic_dec_and_test(&bp->b_io_remaining) xfs_buf_ioend(bp, bp->b_error ? 0 : 1); xfs_buf_rele(bp); <- releases our hold } error = xfs_buf_iowait(bp); <-- sees error; would have waited otherwise if (error) { xfs_buf_ioerror_alert(bp, __func__); xfs_buf_relse(bp); <--- freed here ? but my bp refcounting & lifetime knowledge is lacking :( -Eric From BATV+3759bc676c27a7f28b93+3866+infradead.org+hch@bombadil.srs.infradead.org Tue Mar 25 12:44:22 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 1349E29DF7 for ; Tue, 25 Mar 2014 12:44:22 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay1.corp.sgi.com (Postfix) with ESMTP id F21278F8035 for ; Tue, 25 Mar 2014 10:44:21 -0700 (PDT) X-ASG-Debug-ID: 1395769459-04cbb054b770c830001-NocioJ Received: from bombadil.infradead.org ([198.137.202.9]) by cuda.sgi.com with ESMTP id QTFMoUQPSuyI7gN5 (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Tue, 25 Mar 2014 10:44:19 -0700 (PDT) X-Barracuda-Envelope-From: BATV+3759bc676c27a7f28b93+3866+infradead.org+hch@bombadil.srs.infradead.org X-Barracuda-Apparent-Source-IP: 198.137.202.9 Received: from hch by bombadil.infradead.org with local (Exim 4.80.1 #2 (Red Hat Linux)) id 1WSVOb-0006Ek-NG; Tue, 25 Mar 2014 17:44:17 +0000 Date: Tue, 25 Mar 2014 10:44:17 -0700 From: Christoph Hellwig To: Eric Sandeen Cc: Christoph Hellwig , Eric Sandeen , Brian Foster , xfs-oss Subject: Re: [PATCH] xfs: fix buffer use after free on IO error Message-ID: <20140325174417.GA23300@infradead.org> X-ASG-Orig-Subj: Re: [PATCH] xfs: fix buffer use after free on IO error References: <532CFA12.4040104@redhat.com> <20140325125754.GA18691@bfoster.bfoster> <20140325131705.GB25392@infradead.org> <5331A930.9030402@sandeen.net> <20140325172508.GA4446@infradead.org> <5331BF53.6000300@redhat.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <5331BF53.6000300@redhat.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-SRS-Rewrite: SMTP reverse-path rewritten from by bombadil.infradead.org See http://www.infradead.org/rpr.html X-Barracuda-Connect: UNKNOWN[198.137.202.9] X-Barracuda-Start-Time: 1395769459 X-Barracuda-Encrypted: AES256-SHA X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.70 X-Barracuda-Spam-Status: No, SCORE=0.70 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=MARKETING_SUBJECT, RDNS_NONE X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.4238 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.60 MARKETING_SUBJECT Subject contains popular marketing words 0.10 RDNS_NONE Delivered to trusted network by a host with no rDNS On Tue, Mar 25, 2014 at 10:39:31AM -0700, Eric Sandeen wrote: > so only _xfs_buf_ioend *might* pass something other than 0, and: > > File Function Line > 0 xfs_buf.c xfs_buf_bio_end_io 1197 _xfs_buf_ioend(bp, 1); > 1 xfs_buf.c xfs_buf_iorequest 1377 _xfs_buf_ioend(bp, bp->b_error ? 0 : 1); > > At least up until now that was always called with "1" Right, _was_. But that changes to one always passing 1, and one passing 0 or one with your patch. Or one passing always 1 and one always passing 0 with the suggestion from Brian and me.

Actually we get a recursive callchain there from the I/O error handling. I switched from always 0 to always 1 here in: commit 08023d6dbe840dc4271805a9ea376fcbdee9f744 Author: Christoph Hellwig Date: Mon Jul 2 06:00:04 2012 -0400 xfs: prevent recursion in xfs_buf_iorequest but I never got around fixing the root cause by cleaning up the way we handle buffer I/O completions on a shut down filesystem.

It is possible that the EFI can be pushed to the AIL before a forced shutdown where it gets stuck for following reasons: No complete EFD in the transaction. This can happen if the transaction fails to reserve space or the freeing the extent fails in xfs_bmap_finish(). EFD IOP Abort processing. If xfs_trans_cancel() is called with an abort flag, or if the xfs_trans_commit() is called when the file system is in forced shutdown or if the log buffer write fails, then the EFD iop commands will not remove the EFI from the AIL. If the EFI entry is left on the AIL, xfs_ail_push all_sync() will fail to complete, the unmount will hang, and a reboot is required to get the complete the unmount. Do not free the EFI structure immediately on forced shutdowns, but instead use the IOP calls to match the EFI/EFD entries. A small wrinkle in the mix is the EFI is not automatically placed on the AIL by the IOP routines in the cases but may have made it to the AIL before the abort. We now have to check if the EFI is on the AIL in the abort IOP cases. Signed-off-by: Mark Tinguely --- Dave, as I tried to explain, if the error in extent free happen early enough, the EFD is not usable and is not in the transaction to cause IOP commands to clean up the EFI. It too must be done manually. The "in the AIL" test must be done in the abort IOP commands. fs/xfs/xfs_bmap_util.c | 21 +++++++++++++++---- fs/xfs/xfs_extfree_item.c | 49 +++++++++++++++++++++++++++++++++------------- fs/xfs/xfs_log_recover.c | 3 +- fs/xfs/xfs_trans.h | 2 - 4 files changed, 56 insertions(+), 19 deletions(-) Index: b/fs/xfs/xfs_bmap_util.c =================================================================== --- a/fs/xfs/xfs_bmap_util.c +++ b/fs/xfs/xfs_bmap_util.c @@ -116,12 +116,14 @@ xfs_bmap_finish( error = xfs_trans_reserve(ntp, &tres, 0, 0); if (error) - return error; + goto error_return; + efd = xfs_trans_get_efd(ntp, efi, flist->xbf_count); for (free = flist->xbf_first; free != NULL; free = next) { next = free->xbfi_next; - if ((error = xfs_free_extent(ntp, free->xbfi_startblock, - free->xbfi_blockcount))) { + error = xfs_free_extent(ntp, free->xbfi_startblock, + free->xbfi_blockcount); + if (error) { /* * The bmap free list will be cleaned up at a * higher level.

Each section can contain configuration options in the format OPTION=value when one section is processed xfstests will proceed to next section until all secitons are processed, or an error occur. The name of the section can consist of alphanumeric characters + '_', nothing else is allowed. Name of the section is also used to create results subdirectory for each section. After all the sections are processed summary of all runs is printed out. If the config file does not contain sections, or we're not using config file at all, nothing is changed and xfstests will work the same way as it used to. This is very useful for testing file system with different options. Here is an example of the config file with sections: [ext4_4k_block_size] TEST_DEV=/dev/sda TEST_DIR=/mnt/test SCRATCH_DEV=/dev/sdb SCRATCH_MNT=/mnt/test1 MKFS_OPTIONS="-q -F -b4096" FSTYP=ext4 [ext4_1k_block_size] MKFS_OPTIONS="-q -F -b1024" [ext4_nojournal] MKFS_OPTIONS="-q -F -b4096 -O ^has_journal" [ext4_discard_ssd] MKFS_OPTIONS="-q -F -b4096" TEST_DEV=/dev/sdc SCRATCH_DEV=/dev/sdd MOUNT_OPTIONS="-o discard" Note that once the variable is set it remains set across the sections, so you do not have to specify all the options in all sections. However one have to make sure that unwanted options are not set from previous sections.

The listxattr() function in the vfs actually caps the provided buffer to 64k. This in turn causes an error in XFS, which is capable of filling a larger buffer, and the VFS converts that error into E2BIG. I ran a quick experiment to remove that bit of code from listxattr() and modified your program to use a 128k buffer. Everything still seems to work Ok until I exhaust that buffer. Given that and the fact that listxattr() does an allocation of the user-provided size, I suspect the 64k restriction here is some kind of policy based on memory allocation, but that's a guess. The right fix might be something more involved, such as fixing the interface to handle larger sets of data (e.g., copy direct to a user buffer, or introduce an iterative interface, etc.).

Hi Brian, I don't have a real preference whether the solution is to allow larger buffers or to error out of setxattr even though XFS could handle it, as long as it is no longer possible for an XFS user to get into this state where there is no (easy) way to recover. I think we've hard-coded Ceph to only try up to 64 KB here, but I don't see that limitation documented anywhere and a savvy user can pass in a NULL buffer to get an appropriate length back. In our case, we only hit this limit when something else has already gone a bit off the rails, so getting ENOSPC is just fine. sage > > Brian > > > sage > > > > > > #include > > #include > > #include > > #include > > #include > > #include > > > > int main(int argc, char **argv) > > { > > char *fn = argv[1]; > > char buf[655360]; > > int buflen = sizeof(buf); > > int i; > > > > for (i = 0; i < 10000; ++i) { > > int r = listxattr(fn, buf, buflen); > > if (r < 0) { > > perror("listxattr"); > > return 1; > > } > > char n[100]; > > sprintf(n, "user.foooooooooooooooooooooooooooooooooooooo%d", i); > > r = setxattr(fn, n, "", 0, 0); > > if (r < 0) { > > perror("setxattr"); > > return 1; > > } > > printf("set %d\n", i); > > } > > return 0; > > } > > > > _______________________________________________ > > xfs mailing list > > xfs@oss.sgi.com > > http://oss.sgi.com/mailman/listinfo/xfs > > From fdmanana@gmail.com Thu Mar 27 15:18:59 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=FREEMAIL_FROM,T_DKIM_INVALID autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id 12DB57F3F for ; Thu, 27 Mar 2014 15:18:59 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay2.corp.sgi.com (Postfix) with ESMTP id 05BD0304070 for ; Thu, 27 Mar 2014 13:18:55 -0700 (PDT) X-ASG-Debug-ID: 1395951533-04cbb054b881fc50001-NocioJ Received: from mail-we0-f179.google.com (mail-we0-f179.google.com [74.125.82.179]) by cuda.sgi.com with ESMTP id bBgkovKcOASkzhLv (version=TLSv1 cipher=RC4-SHA bits=128 verify=NO) for ; Thu, 27 Mar 2014 13:18:53 -0700 (PDT) X-Barracuda-Envelope-From: fdmanana@gmail.com X-Barracuda-Apparent-Source-IP: 74.125.82.179 Received: by mail-we0-f179.google.com with SMTP id x48so2110062wes.38 for ; Thu, 27 Mar 2014 13:18:52 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=from:to:cc:subject:date:message-id:in-reply-to:references; bh=raFmiGV72EVJtyht4vt+h5nP/p++mEd2jaG1PR1FJuU=; b=L699UE+6DRrNLVUSeMqGSnuBqLDBN/ejvk4+KqhVbNf43Nche2QsJxbbNML4c8EU7U lVjxrePuap5A9rPC6TyVQCroKvRLPEcAJhvqOdMZb5CgAQxd96ZLonwl8/3k0+1Knflb kpyE59GIUIyRFh/qB2bZ7kwfIhsR/xRcr52PfSWw7pbxHfuZSGq/hK2Bac/4ceNI6A80 XWZAqZ1Q6yHld0Ac2jsz0+9be5galKEJ+O+/11DchtfGqEB/BlxJEi4j5Et2oR8nvTzz OaztAFJuctnZi9LSWhTqVHtOgIB5kJ0NS6z3TljVpMmuGYV3bcj5sn8kZ11IqtAWq/Ta JIag== X-Received: by 10.180.106.167 with SMTP id gv7mr42885156wib.40.1395951532578; Thu, 27 Mar 2014 13:18:52 -0700 (PDT) Received: from debian-vm3.lan (bl5-6-132.dsl.telepac.pt.

This resulted either in sending a wrong path string to the send stream or entering an infinite loop when building it. This happened in the following scenarios: 1) A directory was made a child of another directory which has a lower inode number and has a pending move/rename operation or there's some non-direct ancestor directory with a higher inode number that was renamed/moved too. This made the incremental send code go into an infinite loop when building a path string; 2) A directory was made a child of another directory which has a higher inode number, but the new parent wasn't moved nor renamed. Instead some other ancestor higher in the hierarchy, with an higher inode number too, was moved/renamed too. This made the incremental send code go into an infinite loop when building a path string; 3) An orphan directory is created and at least one of its non-immediate descendent directories have a pending move/rename operation. This made an incremental send issue to the send stream an invalid path string that didn't account for the orphan ancestor directory. Signed-off-by: Filipe David Borba Manana --- V2: Added more tests.

This resulted either in sending a wrong path string +# to the send stream or entering an infinite loop when building it. +# This happened in the following scenarios: +# +# 1) A directory was made a child of another directory which has a lower inode +# number and has a pending move/rename operation or there's some non-direct +# ancestor directory with a higher inode number that was renamed/moved too. +# This made the incremental send code go into an infinite loop when building +# a path string; +# +# 2) A directory was made a child of another directory which has a higher inode +# number, but the new parent wasn't moved nor renamed. Instead some other +# ancestor higher in the hierarchy, with an higher inode number too, was +# moved/renamed too.

When the filesystem is small, so is the 5% low free space threshold that enables preallocation throttling. When the low free space threshold is reduced to a couple GB or so, we can ram into ENOSPC prematurely due to larger, active preallocations. We resolve this condition with an eofblocks scan in the pre-existing ENOSPC retry write sequence. The scan resets outstanding preallocations such that throttling is guaranteed an opportunity to manage future preallocations gracefully into ENOSPC and thus ensures closer to 100% utilization before ENOSPC is reported to userspace. Patches 1-3 make some small enhancements to the eofblocks scanner that facilitate running a scan in the context of a write. Patch 4 adds the actual scan-on-ENOSPC policy. Patch 5 updates the preallocation throttling algorithm to take quota free space into account. Thoughts, reviews, flames appreciated.

Users have reported inefficiencies in these mechanisms when we happen to be dealing with large files on smaller filesystems. This can occur because while prealloc throttling is aggressive under low free space conditions, it is not active until we reach 5% free space or less. For example, a 40GB filesystem has enough space for several files large enough to have multi-GB preallocations at any given time. If those files are slow growing, they might reserve preallocation for long periods of time as well as avoid the background scanner due to frequent modification. If a new file is written under these conditions, said file has no access to this already reserved space and premature ENOSPC is imminent. To handle this scenario, modify the buffered write ENOSPC handling and retry sequence to invoke an eofblocks scan. The eofblocks scan is attempted prior to the inode flush as it is lighter weight and the former is a last resort to free space. In the smaller filesystem scenario, the eofblocks scan resets the usage of preallocation such that when the 5% free space threshold is met, throttling effectively takes over to provide fair and efficient preallocation until legitimate ENOSPC. The eofblocks scan is selective based on the nature of the failure. For example, an EDQUOT failure in a particular quota will use a filtered scan for that quota. Because we don't know which quota might have caused an allocation failure at any given time, we run a scan against each applicable quota determined to be under low free space conditions.

Are there any XFS memory calculators that would have shown me this is a problem to begin with? The answers depend on the cause, which has yet to be determined. Analysis of the requested information should get you an answer pretty quickly, unless the problem turns out to be a bug, which may take a little longer. > Given it walks out of 32 GB of memory I can't be sure that upgrading to 64 or 128 GB will *ever* help this situation. Again, depends on the cause. Don't throw more hardware at this until we have a root cause identified, and it shows more RAM is needed. If this were a desktop and 2 sticks is $50 sure, but not when we're talking registered ECC server sticks to reach 128MB capacity. This 32 to 128 scenario often involves tossing the 32GB as it's not registered or of the wrong rank/clock. > Note: FWIW Un-mounting the filesystem also recovers the memory. Of course.

Out of? Did the OOM-killer actually show up, or did you simply see memory usage rise? The dcache is tenacious. dentries are cached pretty aggressively, and those in turn will pin the vfs/xfs inodes. But memory is there to be used; unless you actually see problems, then the system is likely working as it should be. > Note: FWIW Un-mounting the filesystem also recovers the memory. Yep, that would clear out the cache. -Eric From sandeen@sandeen.net Fri Mar 28 20:56:08 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 689357F3F for ; Fri, 28 Mar 2014 20:56:08 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id 3094D8F8074 for ; Fri, 28 Mar 2014 18:56:07 -0700 (PDT) X-ASG-Debug-ID: 1396058165-04bdf05daaa9ed30001-NocioJ Received: from sandeen.net (sandeen.net [63.231.237.45]) by cuda.sgi.com with ESMTP id H23UyamW7S8leGoK for ; Fri, 28 Mar 2014 18:56:05 -0700 (PDT) X-Barracuda-Envelope-From: sandeen@sandeen.net X-Barracuda-Apparent-Source-IP: 63.231.237.45 Received: from liberator.sandeen.net (liberator.sandeen.net [10.0.0.4]) (using TLSv1 with cipher DHE-RSA-AES128-SHA (128/128 bits)) (No client certificate requested) by sandeen.net (Postfix) with ESMTPSA id 33FDA63BE559; Fri, 28 Mar 2014 20:56:05 -0500 (CDT) Message-ID: <53362834.7090900@sandeen.net> Date: Fri, 28 Mar 2014 20:56:04 -0500 From: Eric Sandeen User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:24.0) Gecko/20100101 Thunderbird/24.4.0 MIME-Version: 1.0 To: Dan Carpenter , Dave Chinner CC: kernel-janitors@vger.kernel.org, xfs@oss.sgi.com Subject: Re: [patch] xfs: extra semi-colon breaks a condition References: <20140328080313.GA25192@mwanda> X-ASG-Orig-Subj: Re: [patch] xfs: extra semi-colon breaks a condition In-Reply-To: <20140328080313.GA25192@mwanda> X-Enigmail-Version: 1.6 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[63.231.237.45] X-Barracuda-Start-Time: 1396058165 X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.4366 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On 3/28/14, 3:03 AM, Dan Carpenter wrote: > There were some extra semi-colons here which mean that we return true > unintentionally. > > Fixes: a49935f200e2 ('xfs: xfs_check_page_type buffer checks need help') that's terrifying.

that's terrifying.
Wonder how errors like th= is one get into the kernel :-) Suppose it's not the main tree, but inst= ead xfs private one.

If the write fails at write_begin time, then we haven't copied any data and the inode size hasn't changed. The intent of the original code looks like it wants to break off any blocks that might have been set up beyond EOF before the write happened to fail. Could you elaborate on how this can kill blocks that might have been written successfully? Doesn't this only affect post-EOF metadata? > + /* > + * If the write is beyond EOF, we only want to kill blocks > + * allocated in this write, not blocks that were previously > + * written successfully. > + */ > + if (pos + len > isize) > + truncate_pagecache_range(inode, pos, pos + len); So the cache truncate now covers the range of the write. What happens if the part of the write is an overwrite? This seems similar to the problem you've described above... should the truncate start at isize instead?

On the server is planed to store 'larger' from 1GB up to 60GB. what would be best settings when formatting with xfs? is it better to use '-b size=4096' or the '512'? should i manipulate the '-i size=' to 2048? or use the default? i also dont get it with the write-disk cache at all, its an linux softraid, is the best then to use 'nobarrier' and let the 'disk write cache on'? or is best solution on linux softraid 'disk write cache' on with xfs barrier on? also, should i tweak with sunit,swidth? and how do i calculate best setting? thanks for any tipps n hints marko -- zbfmail - Mittendrin statt nur Datei!

Known issue, definitely a false positive. We have to change locking algorithms to avoid such deficiencies of lockdep (a case of "lockdep considered harmful", perhaps?) so it's not something I'm about to rush...

Use the defaults. The defaults on md/dm raid will do the right things to configure the filesystem and handle crash safety properly. Unless you have experience with XFS and the storage stack and know exactly what you *need to do*, tweaking knobs will only cause bad things to happen to you and your data.

Already done that. Commit: 93a8614 xfs: fix directory inode iolock lockdep false positive This just changes where the false positives come from. This insanity, for example, where shmem instantiates an inode in the page fault path and so triggers selinux related lockdep fun: http://oss.sgi.com/archives/xfs/2014-02/msg00618.html and this with reclaim state contexts: http://oss.sgi.com/archives/xfs/2014-03/msg00145.html I even hacked a patch to move the inode classes to per-fstype classes, and that just pushed the false positive somewhere else. It's just another horrible game of whack-a-mole, caused by XFS doing something different. The first possible fix: http://oss.sgi.com/archives/xfs/2014-03/msg00146.html is a bit of a big hammer approach, so the approach I'm looking at is the "don't cache mappings in readdir" solution noted here: http://oss.sgi.com/archives/xfs/2014-03/msg00163.html Note that the problem that the additional locking added in 3.13 resolved can not be triggered by anything using the VFS for directory access. The issues is that one of SGI's plug-ins (CXFS) can access directories without going through the VFS and so the internal XFS locking needs to serialise readdir vs directory modification safely....

The existance of many different environments people have built up around it is one of the strengths of xfstests. Hence the very act of considering enforcing One True Way of running xfstests is, IMO, harmful to the wider filesystem and xfstests community. You're also being rather presumptive that the existence of xfstests-bld requires us to change anything about the way xfstests is run. Your xfstests environment - while interesting and potentially useful to others - is not unique and is not the only way of doing in-place testing. > especially given that based on a challenge which > Greg K-H gave us at the kernel pannel at Collab Summit, ^^^^ Hmmmm. Not the way I remember it. Perhaps I should go look at the video and check that Greg was addressing me directly as the xfstests maintainer with those comments. After all, those lights on stage can be blinding..... > we'll at least > be looking at cleaning up and then trying to get into the linux kernel > mainline sources some combination of xfstests plus some infrastructure > automation (perhaps strongly based on what I've been working here in > the xfstests-bld tree) to run xfstests. Now you're pre-empting the discussions we need to have about xfstests and what best serves it's user community. xfstests is consumed by many end-users that are not kernel developers (e.g. distro QA departments, storage product vendors, etc), so anything we decide needs to work not only for kernel developers but also benefit the wider community of xfstests users. There are many advantages even to filesystem developers to staying outside the kernel tree. Think about this for a moment: to update xfstests to pick up a new regression test to test a regression, you need to update the kernel tree. That will also pull in the fix for the regression. To revert the kernel tree to before the fix came in so that you can run before/after fix comfirmation, it also removes the new regression test from xfstests harness and so you can't run the regression test in place. IOWs, bisects based on regression tests become rather difficult because of this - bisects require the test not to change from bisection point to bisection point, and running xfstests directly out of the kernel tree that you are building kernels from during the bisect is going to have this exact problem. Therefore, *if* we move xfstests to the kernel tree we will still need to maintain that flexibility and configurability of the current code so that developers and external users can continue to package the tests up into their own QA environment. That implies we need to work out packaging and distribution issues that we don't currently care about, as well as some method of in-place test execution for people like Greg doing -stable kernel testing. So, rather than going off half-cocked about some random build environment for xfstests defining the future of filesystem testing, we need to step back and think about what Greg actually wants. That is, "make tests" in the kernel tests/ tree to be able to run xfstests. That's the problem Greg wanted solved, and that does not necessarily mean wholesale changes to xfstests or it's development model. And one possible solution to this is simply making the kernel tests/ directory just another downstream consumer of the upstream xfstests project....

In continuation of the work of making the process of non linear editing of media files faster, we introduce here the new flag FALLOC_FL_INSERT_RANGE for fallocate. This flag will work opposite to the newly added FALLOC_FL_COLLAPSE_RANGE flag. As such, specifying FALLOC_FL_INSERT_RANGE flag will insert zeroed-out space in between the file within the range specified by offset and len. User can write new data in this space. e.g. ads. Like collapse range, currently we have the limitation that offset and len should be block size aligned for both XFS and Ext4. The semantics of the flag are : 1) It allocates new zeroed out on disk space of len bytes starting at offset byte without overwriting any existing data. All the data blocks from offset to EOF are shifted towards right to make space for inserting new blocks 2) It should be used exclusively. No other fallocate flag in combination. 3) Offset and length supplied to fallocate should be fs block size aligned in case of xfs and ext4. 4) Insert range does not work for the case when offset is overlapping/beyond i_size. If the user wants to allocate space at the end of file they are advised to use either ftruncate(2) or fallocate(2) with mode 0. 5) It increses the size of file by len bytes.

If the computed block number is not the starting block of the extent, split the extent such that the block number is the starting block of the extent. 3) Shift all the extents which are lying bewteen [offset, last allocated extent] towards right by len bytes. This step will make a hole of len bytes at offset. 4) Allocate unwritten extents for the hole created in step 3. 5) Update the i_size of inode by len bytes.

If the computed block number is not the starting block of the extent, split the extent such that the block number is the starting block of the extent. 3) Shift all the extents which are lying bewteen [offset, last allocated extent] towards right by len bytes. This step will make a hole of len bytes at offset. 4) Allocate unwritten extents for the hole created in step 3. 5) Update the i_size of inode by len bytes.

I know there were still problems when I left because generic/127 was failing on 1k block size filesystems, but I haven't yet had a chance to get back to determine if the bug was the broken code in xfs_check_page_types() that Dan Carpenter noticed. Were you running with that fix?

If this operation fails, the EFI will stay on the AIL and prevents the xfs_ail_push all_sync() from completing and the mount will fail to unmount. Rather than have a special log recovery flag XFS_EFI_RECOVERED to decrement the EFI/EFD counter, call the same decrement function from the log recovery routine that is called then the EFI is added to the AIL from a log write. Remove all other unprocessed EFIs from the log recovery AIL when one is discovered in error. Signed-off-by: Mark Tinguely --- v2 per Brian's feedback: decrement the EFI counter again when removing EFI entries after the entry with the error. add comment in xlog_recover_process_efis() where we delete the EFIs. v1: Rewritten with suggestions from Dave.

Well, it's been over a week now and you're asking me to trust that someone I don't know and who has never submitted an xfstests before to do something in a timely manner so we can test a critical bug fix during a merge window. I'm willing to be pleasently surprised, but history tells me that people that report bugs rarely follow up with xfstest cases and it's usually the developer that fixes the bug that generates the xfstests patch. So if the xfstests patch doesn't arrive in the next few hours, can you please do that for us so I can get this sorted out for the merge window?

I'd much prefer that we don't bury data writeback deep in the EOF block freeing code - we've done a lot of work in the past to remove exactly that sort of behaviour from XFS inode scanners. I'd prefer to see something like this: if (ret == -EDQUOT && !enospc) { enospc = 1; xfs_inode_free_quota_eofblocks(ip); goto retry; else if (ret == -ENOSPC && !enospc) { enospc = 1; xfs_flush_inodes(ip->i_mount); .... xfs_icache_free_eofblocks(ip->i_mount, &eofb); goto retry; } This way has specific behaviours for EDQUOT vs ENOSPC, and we treat them appropriately with a minimum of differences.

Dave, I think we need to take a step back and clear a little confusion here. There are 2 different directory bugs. 1) Freeing of a already free extent. It presents with the error: XFS: Internal error XFS_WANT_CORRUPTED_GOTO at line 16XX of file fs/xfs/xfs_alloc.c. Could be a right or a left edge (or both) that is free. Morgan Meyers sent the latest occurrence on March 12, but others have been seeing it in the community code in the last few mounts. SGI has been seeing it lately with big customers and it has occurred off and on for 7-8 years according to our bug database. It is a nasty bug that can can cause corruption. As I mentioned last week in the analysis of Morgan's metadata dump, XFS can allocate the same buffer multiple times. In his metadata dump there is a directory block and inode clusters that also allocated as user blocks. These duplicate allocated blocks are land mines waiting to go off either when written to by one owner or when when both allocations are removed which causes the XFS_WANT_CORRUPTED_GOTO forced shutdown. 2) Hannes Frederic Sowa found a different directory bug on Thursday, March 27. He included a replicator. I bisected the source of the this bug on Thursday. Walked the bisected patch on Friday and posted the patch. The idea to make a xfstest from the replicator was also made on March 28. This bug has been only known for 3 business days. I already promised that a xfstest will be made. If you need to verify the problem and the patch, there already is a replicator. --Mark.

I am merely pushing xfstests-bld because it's better that more people run tests. And if it makes it easier for people to run tests because there is a turn-key way to run them, so much the better. Having a diversity of ways of running xfstests is good. Having lots of people run xfstests, even if many of them run it the same way, is better. > You're also being rather presumptive that the existence of > xfstests-bld requires us to change anything about the way xfstests > is run.

Sorry, I thought in the discussions we had afterwards you agreed with me that *some* way of running xfststs easily was going to be a requirement, as it is somewhat doubtful that most non-file system developers will have the patience to deal with the "some assembly required" in order to actually run xfstests, and actually putting xfstests into the kernel sources wasn't going to be particularly useful unless we have some way of making it possible to run the tests in a semi-automated fashion. Whether that method is based on what I have in xfstests-bld, or some other way is I agree certainly up for discussion. At the moment the system I have is only set up for ext4, although I will happily accept patches and work with other file system developers to enhance it so it can work with other file systems. And of course, whether changes in the mainline kernel tree are manually propagated changes from the xfstests.git tree, or whether primary development happens in the kernel tree, is ultimately going to be up to you and the XFS developers who have stewardship of xfstests. I'm not sure I would be that excited about manual propagation of changes from one git tree to another, but that is of course, up to you. Cheers, - Ted
