>Description:

With Solaris 2.[68] as clients, and -CURRENT of Oct. 17 as server:
ls on client works, but ls -l waits for a timeout once for each file
in the directory, and issues a 'NFS getacl failed' message.

The server is not multi-homed, and a packet capture shows no trace of
address mismatch problems. One interesting thing is that the client
first does GETATTR on the file (and apparently gets a reply), and
then sends some other RPC, to which the server never replies.
Could this be the getacl request mentioned in the client error message?
I see no mention of getacl whatsoever in the -CURRENT server code. If
no such function is implemented, shouldn't we reject the request?

A packet capture is available at
  http://www.infres.enst.fr/~quinot/nfs.cap

Client is  137.194.192.1, server is 137.194.162.11. The test consists
in first performing an 'ls' on one file, then an 'ls -l' on the same
file. Result:

ls photos-ta; ls -l photos-ta
photos-ta
NFS getacl failed for server shalmaneser.enst.fr: error 5 (RPC: Timed
out)
-rw-------   1 quinot   astre        474 Oct 18 14:17 photos-ta

This issue was brought up on current@freebsd.org, but no reply was made.

>How-To-Repeat:

Export an NFS file system from a FreeBSD 5-CURRENT server to a Solaris 2.8
client. Do an 'ls' on an existing file on that FS (works correctly),
do an 'ls -l' (hanges, times out, displays error message before returning
correct data).

>Fix:
	None known so far.
	Note: Trying to launch mountd with '-2' and to mount the FS with
	'-o vers=2' on the client results in mount hanging on the client
	(although mountd logs a 'mount request succeeded').
