* ocfs2: use generic posix ACL infrastructureChristoph Hellwig2014-01-251-5/+8
| | | | | | | | | 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. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* fs: take the ACL checks to common codeChristoph Hellwig2011-07-251-1/+1
| | | | | | | | | Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* ocfs2: Always include ACL supportJan Kara2009-10-281-22/+0
| | | | | | | | | To become consistent with filesystems such as XFS or BTRFS, make posix ACLs always available. This also reduces possibility of misconfiguration on admin's side. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Joel Becker <joel.becker@oracle.com>

* ocfs2: add POSIX ACL APITiger Yang2009-01-051-0/+29
This patch adds POSIX ACL(access control lists) APIs in ocfs2. We convert struct posix_acl to many ocfs2_acl_entry and regard them as an extended attribute entry. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
