gNFS: Incorrect NFS ACL encoding for XFS
Problem: Incorrect NFS ACL encoding causes "system.posix_acl_default" setxattr failure on bricks on XFS file system. XFS (potentially others?) doesn't understand when the 0x10 prefix is added to the ACL type field for default ACLs (which the Linux NFS client adds) which causes setfacl()->setxattr() to fail silently. NFS client adds NFS_ACL_DEFAULT(0x1000) for default ACL. FIX: Mask the prefix (added by NFS client) OFF, so the setfacl is not rejected when it hits the FS. Original patch by: "Richard Wareing" Change-Id: I17ad27d84f030cdea8396eb667ee031f0d41b396 BUG: 1009210 Signed-off-by: Santosh Kumar Pradhan <spradhan@redhat.com> Reviewed-on: http://review.gluster.org/5980 Reviewed-by: Amar Tumballi <amarts@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
