The month of June saw a few important bug fixes for the Linux 2.6.35
release candidates. That includes ensuring that files used for the
swapext ioctl are writable to the user, and doing proper validation
of inodes coming from untrusted sources, such as NFS exporting and
the open by handle system calls. The main work however has been
focused on development for the Linux 2.6.36 merge window, including
merging various patches that have been out on the mainline list
for a long time. Highlights include further performance improvements
for sync heavy metadata workloads, stack space reduction in the
writeback path and improvements of the XFS tracing infrastructure.
Also after some discussion the remaining hooks for DMAPI are going
to be dropped in mainline. As a replacement a tree containing
full DMAPI support with a slightly cleaner XFS interaction will be
hosted by SGI.
On the userspace side June was a rather slow month, with no updates
to xfsprogs and xfsdump at all, and just one new test case and a cleanup
applied to xfstests.
