[PATCH 0/6] nfsd: add support for NFSv4 callbacks over IPv6 (try #5)

[Jeff Layton <jlayton@redhat.com>]

Fifth attempt at a patchset to add support for NFSv4 callbacks over
IPv6. Changes from last patchset are mostly to address Chuck's comments:

1) made the new address comparison and copy routines into static inlines
and added them to clnt.h. Ditto for the get_scope_id function.

2) combined the patch to change nfs4_cb_conn to hold address in
sockaddr_storage with the one to convert gen_callback to use
rpc_uaddr2sockaddr. That eliminates changes to the parse_ipv4 function
that eventually gets ripped out.

Tested using opensolaris and linux and verifying that delegations could
be properly recalled. I also tested mounts to the server's link-local
address and verified that the callback channel connected correctly.

Jeff Layton (6):
  sunrpc: add routine for comparing addresses
  sunrpc: add common routine for copying address portion of a sockaddr
  nfsd: make nfs4_client->cl_addr a struct sockaddr_storage
  nfsd: convert nfs4_cb_conn struct to hold address in sockaddr_storage
  nfsd: add support for NFSv4 callbacks over IPv6
  nfsd: populate sin6_scope_id on callback address with scopeid from
    rq_addr on SETCLIENTID call
