logs: Do selective logging for errnos

2014-10-22T07:32:40+00:00

        Backport of http://review.gluster.org/8918
                    http://review.gluster.org/8955

Problem:
Just after replace-brick the mount logs are filled with ENOENT/ESTALE
warning logs because the file is yet to be self-healed now that the
brick is new.

Fix:
Do conditional logging for the logs. ENOENT/ESTALE will be logged at
lower log level. Only when debug logs are enabled, these logs will
be written to the logfile.

client_t: Fix memory leaks

- Assign frame->root->client so that gf_client_unref happens
  in server_connection_cleanup_flush_cbk
- Avoid taking extra ref in gf_client_get

TODO:
The whole reason why there are two types of refs
bind, ref-count is to avoid lock inside lock which
is not the case now. I will be sending one more patch
which will accomplish that as well as changing the
tablearray to list

protocol/server: '/s/ESTALE/ENOENT' only in lookup path

2014-07-14T09:22:14+00:00

Problem:
[1] modified the server resolver code to send ENOENT instead of
ESTALE to older clients for all FOPS. This caused dht_mkdir
to fail under certain conditions (see bug description).

Fix:
Since [1] is needed by AFR only in its lookup path, reverted the changes
introduced by [1]  in resolve_entry_simple () an resolve_inode_simple () and
made the change instead in server_lookup_resume().

2014-07-08T10:36:18+00:00

While accessing the procedures of given RPC program in,
rpcsvc_get_program_vector_sizer(), It was not checking boundary
conditions which would cause buffer overflow and subsequently SEGV.

Make sure rpcsvc_actor_t arrays have numactors number of actors.

FIX:
Validate the RPC procedure number before fetching the actor.

rpc: implement server.manage-gids for group resolving on the bricks

2014-05-23T08:34:02+00:00

The new volume option 'server.manage-gids' can be enabled in
environments where a user belongs to more than the current absolute
maximum of 93 groups. This option triggers the following behavior:

1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or
   libgfapi) will contain only one (1) auxiliary group, instead of
   a full list. This reduces network usage and prevents problems in
   encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes.
2. The single group in the RPC Calls received by the server is replaced
   by resolving the groups server-side. Permission checks and similar in
   lower xlators are applied against the full list of groups where the
   user belongs to, and not the single auxiliary group that the client
   sent.

gNFS: Set default outstanding RPC limit to 16

2014-03-07T20:11:28+00:00

Backport of http://review.gluster.org/#/c/6696/

With 64, NFS server hangs with large I/O load (~ 64 threads writing
to NFS server). The test results from Ben England (Performance expert)
suggest to set it as 16 instead of 64.
