xfs: fix sgid inheritance for subdirectories inheriting default acls [V3]
XFS removes sgid bits of subdirectories under a directory containing a default acl. When a default acl is set, it implies xfs to call xfs_setattr_nonsize() in its code path. Such function is shared among mkdir and chmod system calls, and does some checks unneeded by mkdir (calling inode_change_ok()). Such checks remove sgid bit from the inode after it has been granted. With this patch, we extend the meaning of XFS_ATTR_NOACL flag to avoid these checks when acls are being inherited (thanks hch). Also, xfs_setattr_mode, doesn't need to re-check for group id and capabilities permissions, this only implies in another try to remove sgid bit from the directories. Such check is already done either on inode_change_ok() or xfs_setattr_nonsize(). Changelog: V2: Extends the meaning of XFS_ATTR_NOACL instead of wrap the tests into another function V3: Remove S_ISDIR check in xfs_setattr_nonsize() from the patch Signed-off-by: Carlos Maiolino <cmaiolino@redhat.com> Reviewed-by: Ben Myers <bpm@sgi.com> Signed-off-by: Ben Myers <bpm@sgi.com>
