Hi.
Here is a patch to modify the NFS server to register the NFS_ACL
services with the rpcbind daemon. This allows the client to
ping for the existence of the NFS_ACL support via commands such
as "rpcinfo -t <server> nfs_acl".
This patch also modifies the NFS_ACL support so that responses
to version 2 NULLPROC requests can be made.
The changelog for the patch which turned off this functionality
mentioned something about not registering the NFS_ACL as being
part of some tradition. I can't find this tradition and the
only other implementation which supports NFS_ACL does register
them with the rpcbind daemon.
Thanx...
ps
