ocfs2: take inode lock in ocfs2_iop_set/get_acl()

2015-09-04T23:54:41+00:00

This bug in mainline code is pointed out by Mark Fasheh.  When
ocfs2_iop_set_acl() and ocfs2_iop_get_acl() are entered from VFS layer,
inode lock is not held.  This seems to be regression from older kernels.
The patch is to fix that.

ocfs2: call ocfs2_update_inode_fsync_trans when updating any inode

2014-04-03T23:20:56+00:00

Ensure that ocfs2_update_inode_fsync_trans() is called any time we touch
an inode in a given transaction.  This is a follow-on to the previous
patch to reduce lock contention and deadlocking during an fsync
operation.

ocfs2: use generic posix ACL infrastructure

2014-01-26T04:58:21+00:00

This contains some major refactoring for the create path so that
inodes are created with the right mode to start with instead of
fixing it up later.

fs: make posix_acl_create more useful

2014-01-26T04:58:18+00:00

Rename the current posix_acl_created to __posix_acl_create and add
a fully featured helper to set up the ACLs on file creation that
uses get_acl().

ocfs2: clean up dead code in ocfs2_acl_from_xattr()

2013-09-11T22:56:39+00:00

In ocfs2_acl_from_xattr(), if size is less than sizeof(struct
posix_acl_entry), it returns ERR_PTR(-EINVAL) directly.  Then assign (size
/ sizeof(struct posix_acl_entry)) to count which will be at least 1, that
means the following branch (count < 0) and (count == 0) will never be
true.

ocfs2: Handle kuids and kgids in acl/xattr conversions.

2013-02-13T14:00:56+00:00

Explicitly deal with the different kinds of acls because they need
different conversions.

userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr

2012-09-18T08:01:35+00:00

 - Pass the user namespace the uid and gid values in the xattr are stored
   in into posix_acl_from_xattr.

 - Pass the user namespace kuid and kgid values should be converted into
   when storing uid and gid values in an xattr in posix_acl_to_xattr.

- Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
  pass in &init_user_ns.

In the short term this change is not strictly needed but it makes the
code clearer.  In the longer term this change is necessary to be able to
mount filesystems outside of the initial user namespace that natively
store posix acls in the linux xattr format.
