rpcsvc: Add latency tracking for rpc programs

2020-09-07T19:15:10+00:00

Added latency tracking of rpc-handling code. With this change we
should be able to monitor the amount of time rpc-handling code is
consuming for each of the rpc call.

libglusterfs: fix dict leak

2020-09-04T13:43:30+00:00

Problem:
gf_rev_dns_lookup_cached() allocated struct dnscache->dict if it was null
but the freeing was left to the caller.

Fix:
Moved dict allocation and freeing into corresponding init and fini
routines so that its easier for the caller to avoid such leaks.

fuse: fetch arbitrary number of groups from /proc/[pid]/status

2020-08-21T14:12:09+00:00

Glusterfs so far constrained itself with an arbitrary limit (32)
for the number of groups read from /proc/[pid]/status (this was
the number of groups shown there prior to Linux commit
v3.7-9553-g8d238027b87e (v3.8-rc1~74^2~59); since this commit, all
groups are shown).

With this change we'll read groups up to the number Glusterfs
supports in general (64k).

Note: the actual number of groups that are made use of in a
regular Glusterfs setup shall still be capped at ~93 due to limitations
of the RPC transport. To be able to handle more groups than that,
brick side gid resolution (server.manage-gids option) can be used along
with NIS, LDAP or other such networked directory service (see
https://github.com/gluster/glusterdocs/blob/5ba15a2/docs/Administrator%20Guide/Handling-of-users-with-many-groups.md#limit-in-the-glusterfs-protocol
).

Also adding some diagnostic messages to frame_fill_groups().

libglusterfs: add functions to calculate time difference

2020-08-21T03:56:52+00:00

Add gf_tvdiff() and gf_tsdiff() to calculate the difference
between 'struct timeval' and 'struct timespec' values, use
them where appropriate.

posix: Implement a janitor thread to close fd

2020-08-20T12:11:43+00:00

Problem: In the commit fb20713b380e1df8d7f9e9df96563be2f9144fd6 we use
         syntask to close fd but we have found the patch is reducing the
         performance

Solution: Use janitor thread to close fd's and save the pfd ctx into
          ctx janitor list and also save the posix_xlator into pfd object to
          avoid the race condition during cleanup in brick_mux environment
