protocol/server: Relax lktable finodelk del_locker check

2013-08-18T00:21:46+00:00

Problem:
Client xlator issues finodelk using anon-fd when the fd is not
opened on the file. This can also happen between attempts to re-open
the file after client disconnects. It can so happen that lock is taken
using anon-fd and the file is now re-opened and unlock would come with
re-opened fd. This will lead to leak in lk-table entry, which also
holds reference to fd which leads to fd-leak on the brick.

Fix:
Don't check for fds to be equal for tracking finodelks.
Since inodelk is identified by (gfid, connection, lk-owner)
fd equality is not needed.

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.)
