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"
