Problems with ACL inheritance and chacl

[John Trostel <jtrostel@xxxxxxxxxx>]

I am seeing some strange behavior with both ACL inheritance and chacl
operation.  Does anyone else see this or is my build faulty?

I started with a freshly formatted xfs partition on /mnt/xfs_part.

I set the access, default and mask ACLs for this parition as follows:

  [root@jtsdell /mnt]# mount /mnt/xfs_part/

  [root@jtsdell /mnt]# chacl -l xfs_part/
  xfs_part/ []
        
  [root@jtsdell /mnt]# chacl -b u::rwx,g::rwx,o::rwx,m::rwx u::rwx,g::rwx,o::rwx
                           xfs_part

  [root@jtsdell /mnt]# chacl -l xfs_part/
  xfs_part/ [u::rwx,g::rwx,o::rwx,m::rwx/u::rwx,g::rwx,o::rwx]


So far... so good!


  [root@jtsdell /mnt]# exit
  exit

  [jt@jtsdell xfs_backup]$ cd ..

  [jt@jtsdell /mnt]$ cd xfs_part

  [jt@jtsdell xfs_part]$ ls

  [jt@jtsdell xfs_part]$ touch jt.txt

  [jt@jtsdell xfs_part]$ chacl -l jt.txt
  jt.txt [u::rw-,g::rw-,o::r--]

Not good... Shouldn't this get the default ACLs u::rwx,g::rwx,o::rwx ?

  [jt@jtsdell xfs_part]$ su
  Password:

  [root@jtsdell xfs_part]# touch root.txt
 
  [root@jtsdell xfs_part]# chacl -l root.txt
  root.txt [u::rw-,g::rw-,o::r--]

Hmm... root has the same problem!

  [root@jtsdell xfs_part]# chacl -B root.txt
  chacl: error removing access acl on "root.txt": Invalid argument
  chacl: error removing default acl on "root.txt": Invalid argument

  [root@jtsdell
  xfs_part]# chacl -D root.txt
  chacl: error removing default acl on "root.txt": Invalid argument

Shouldn't 'chacl' be removing my ACLs here?

I can go back and manually set the ACLs without problem, but they don't seem to
propogate down correctly and chacl removal seems flawed.  I have downloaded a
fresh copy of the CVS tree and will try with an updated kernel and cmd tools
later today.  I noticed that chacl hasn't been changed in a while. Maybe it
bears looking into.... (I'll take a peek while the system is hoisting itself by
it's own petard!)
