Here's a set of patches that make xfstests (mostly) work with the in-kernel
AFS client. It has to allow for a number of features of AFS, in
particular:
(*) AFS has its own permissions service that makes use of authentication
tokens obtained from such as kerberos and uses this in combination
with ACLs to determine file access rights. This overrides the use of
UNIX permissions and using su to impersonate another user doesn't
work.
(*) AFS sets the inode UID field to the user ID associated with the
authentication token, not the client's fsuid when creating.
(*) AFS doesn't support SUID/SGID/SVTX bits and doesn't propagate SGID on
directories, though it will propagate the GID.
(*) chown is rejected unless you have an authentication token that
indicates you're the owner of the file.
I've added fixes/workarounds for the above. There are five -g quick tests
that fail if unauthenticated:
- generic/258
- generic/634
Fail because they try to use dates that the server refuses to
handle (and gives EOVERFLOW for).
- generic/478
Fails because AFS file locking can't lock ranges.
- generic/633
Fails because of chown.
- generic/696
Fails because AFS doesn't propagate SGID in mkdir. This may be a
client (kernel) bug, a server bug or a design feature.
And if authenticated, the following additional failures occur because AFS
uses its own ACLs and authentication:
- generic/087
- generic/126
- generic/193
- generic/088

Changes
=======
ver #2)
- Rebased.
- Dropped the patches to handle the DIO blocksize being 1 as none of the
quick tests now use it on AFS.
- Changed generic/696 to not supply "noacl" to AFS.
