vfs: Check attribute names in posix acl xattr handers
The get and set operations of the POSIX ACL xattr handlers failed to check the attribute names, so all names with "system.posix_acl_access" or "system.posix_acl_default" as a prefix were accepted. Reject invalid names from now on. Signed-off-by: NAndreas Gruenbacher <agruenba@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
