filesystem permissions should never restrict access and the actual
access checks are done by smbd in userspace.
To better cope with POSIX mode changes via other protocols (eg NFS) or
local filesystem access, add the following tweaks:
o validate ACL blob: if POSIX mode is not 0777/0666 discard the ACL blob
from the xattr and synthesize a default ACL based on the POSIX mode

Previously the module recursed to the next parent directory until the

root didn't contain an ACL xattr either a default ACL would be used.
This commit removed this recursive scanning and replaces it with the
same mechanism used by vfs_acl_xattr: by setting "inherit acls = yes"
just let smbd do the heavy lefting and inheritance.
For any file without ACL xattr we still synthesize a default ACL,

use xattrs in that namesspace will fail with EOPNOTSUPP, regardless of

Using the "security" namespace instead makes this module generally
usable with Linux filesystem xattrs as storage backend.
Additionally prefix the xattr name with "_ndr". This is in preperation
of later commits that add a ACL blob marshalling format based on XDR. To
avoid xattr name collision, both format will use distinct xattr names by
