protocol/server: do not do root-squashing for trusted clients

2014-02-11T07:32:05+00:00

* As of now clients mounting within the storage pool using that machine's
  ip/hostname are trusted clients (i.e clients local to the glusterd).

* Be careful when the request itself comes in as nfsnobody (ex: posix tests).
  So move the squashing part to protocol/server when it creates a new frame
  for the request, instead of auth part of rpc layer.

* For nfs servers do root-squashing without checking if it is trusted client,
  as all the nfs servers would be running within the storage pool, hence will
  be trusted clients for the bricks.

* Provide one more option for mounting which actually says root-squash
  should/should not happen. This value is given priority only for the trusted
  clients. For non trusted clients, the volume option takes the priority. But
  for trusted clients if root-squash should not happen, then they have to be
  mounted with root-squash=no option. (This is done because by default
  blocking root-squashing for the trusted clients will cause problems for smb
  and UFO clients for which the requests have to be squashed if the option is
  enabled).

* For geo-replication and defrag clients do not do root-squashing.

* Introduce a new option in open-behind for doing read after successful open.

libglusterfs/client_t client_t implementation, phase 1

2013-07-30T05:22:21+00:00

Implementation of client_t

The feature page for client_t is at
http://www.gluster.org/community/documentation/index.php/Planning34/client_t

In addition to adding libglusterfs/client_t.[ch] it also extracts/moves
the locktable functionality from xlators/protocol/server to libglusterfs,
where it is used; thus it may now be shared by other xlators too.

This patch is large as it is. Hooking up the state dump is left to do
in phase 2 of this patch set.

(N.B. this change/patch-set supercedes previous change 3689, which was
corrupted during a rebase. That change will be abandoned.)
