Without looking at your details, apologies: First, if you want an ace on a directory to be inherited by files and directories created under that directory, make sure you're setting the f and d flags (see nfs4_getfacl -H). Second, there's a umask problem: posix acl inheritance overrides the umask, but nfs4 acl inheritance isn't doing that. (The client combines the create mode and the umask and sets both together, there's no way for the server to even tell what the umask is.) (We should do something about this if we can: maybe modifying the client to scan the directory acl for any inheritable aces and leaving out the umask if they're found? It has the obvious race, but I seem to recall we live with that in the v3 case. Or maybe there's something more clever, but this comes up every now and then and I can't remember a better solution.) --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
