Problem: It was not possible to configure more than 7712 quota limits.
This was because a stack buffer of size 131072 was used to read from
quota.conf file. In the new format of quota.conf file each gfid entry
takes 17bytes (16byte gfid + 1 byte type). So, the buf_size was not a
multiple of gfid entry size and as per code this was considered as
corruption.
Solution: make buf size multiple of gfid entry size

Problem: when server-quorum-type is server, after restarting glusterd
in the node which is up, gluster volume status is giving incorrect
information.
Fix: check whether server is blank, before adding other keys into the
dictionary.

The restriction of using fds opened by the same Pid means fds cannot
be shared across threads of multithreaded application. Note that fops
from kernel have different Pid for different threads. Imagine
following sequence of operations:
* Turn off performance.open-behind
* Thread t1 opens an fd - fd1 - on file "file". Let's assume nodeid of
"file" is "nodeid-file".
* Thread t2 does RENAME ("newfile", "file"). Let's assume nodeid of
"newfile" as "nodeid-newfile".
* t2 proceeds to do fstat (fd1)
The above set of operations can sometimes result in ESTALE/ENOENT
errors. RENAME overwrites "file" with "newfile" changing its nodeid
from "nodeid-file" to "nodeid-newfile" and post RENAME, "nodeid-file" is
removed from the backend. If fstat carries nodeid-file as argument,
which can happen if lookup has not refreshed the nodeid of "file" and
since t2 doesn't have an fd opened, fuse_getattr_resume uses STAT
which will fail as "nodeid-file" no longer exists.
Since the above set of operations and sharing of fds across
multiple threads are valid, this is a bug.
The fix is to use any fd opened on the inode. In this specific example
fuse_getattr_resume will find fd1 and winds down the call as fstat
(fd1) which won't fail.
Cross-checked with "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for
any security issues with this solution and he approves the solution.
Thanks to "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for all the
pointers and discussions.

Problems: According to Coverity Issue ID 207
issues are as follows-
a-) Dereferencing "this" pointer without checking if it points to NULL.
b-) The IF condition on line 1750 should check
if any *one* of dict, this or peerinfo is NULL
and not *all*.
Fix:
Replace the && operator with || to check if any *one* of
this, dict or peerinfo is NULL and then execute out label.

Problem: control flow won't enter into if block as volname is always
NULL and return value of function synctask_barrier_init is unchecked.
Fix: remove condition checking which is always resulting in false,
and removing if block which is always unreachable. As a result of
removal of condition checking volname became a unused variable,
so remove declaration of volname.
assign return valur of synctask_barrier_init to ret, if it nonzero
value goto out.

Starting in Fedora 26 which has gcc-7.1.x, -Wformat-trunction is enabled
with -Wformat, resulting in a flood of new warnings. This many warnings
is a concern because it makes it hard(er) to see other warnings that
should be addressed.
An example is at
https://kojipkgs.fedoraproject.org//packages/glusterfs/3.12.0/1.fc28/data/logs/x86_64/build.log
For more info see https://review.gluster.org/#/c/18267/

Summary:
When mnt3_resolve_subdir_cbk() fails (this can happen when racing
operations), authorized_path is sometimes NULL. We try to run strlen()
on this path and as a result we crash. This diff fixes that by checking
if path is NULL before dereferencing it.
Test Plan: Run with patch and observe that there is no crash. Prove test
for auth code.

glusterd's brick restart logic is not always sequential as there is
atleast three different ways how the bricks are restarted.
1. through friend-sm and glusterd_spawn_daemons ()
2. through friend-sm and handling volume quorum action
3. through friend handshaking when there is a mimatch on quorum on
friend import.
In a brick multiplexing setup, glusterd ended up trying to spawn the
same brick process couple of times as almost in fraction of milliseconds
two threads hit glusterd_brick_start () because of which glusterd didn't
have any choice of rejecting any one of them as for both the case brick
start criteria met.
As a solution, it'd be better to control this madness by two different
flags, one is a boolean called start_triggered which indicates a brick
start has been triggered and it continues to be true till a brick dies
or killed, the second is a mutex lock to ensure for a particular brick
we don't end up getting into glusterd_brick_start () more than once at
same point of time.

While stopping the brick which is to be reset and replaced delete_brick
flag was passed as true which resulted glusterd to free up to source
brick before the actual operation. This results commit force to fail
failing to find the source brickinfo.
