Setting frame->local = local immediately after mem_get0.
In this case, SVC_STACK_UNWIND will take of freeing the memory.

xlators/features/quota/src/quota.c quota_log_usage function.
The quota_log_helper() function applies memory
for path through inode_path(), should be GF_FREE().

In many cases, we were freely allocating long keys with no need.
Smaller char arrays are just fine almost anywhere, so just went ahead
and looked where they we can use smaller ones.
In some cases, annotated the functions as static and the prefixes
passed as const as it was easier to read and understand.
Where relevant, converted the dict functions to use known key length.

When using inode_ctx_get() or inode_ctx_set(), a 'uint64_t *' is expected.
In many cases, the value to retrieve or store is a pointer, which will be
of smaller size in some architectures (for example 32-bits). In this case,
directly passing the address of the pointer casted to an 'uint64_t *' is
wrong and can cause memory corruption.

All the structs present inside xlators/features/leases have been
re-aligned into memory efficient way. Changes are made in such a way
that every members are 8 byte aligned and no padding is left out in
the 8 byte line. Manual padding has been added to remove compile time
padding (which happens at the end of the struct). This manual padding
is for development and debugging benefits. It lets to use -Wpadded
option and raise warnings from the remaining structs where compile time
padding happens.

Changes in locks xlator:
Added support for per-domain inodelk count requests.
Caller needs to set GLUSTERFS_MULTIPLE_DOM_LK_CNT_REQUESTS key in the
dict and then set each key with name
'GLUSTERFS_INODELK_DOM_PREFIX:<domain name>'.
In the response dict, the xlator will send the per domain count as
values for each of these keys.
Changes in AFR:
Replaced afr_selfheal_locked_inspect() with afr_lockless_inspect(). Logic has
been added to make the latter behave same as the former, thus not
breaking the current heal info output behaviour.

Problem:
When touch is used to create a file, the ctime is not matching
atime and mtime which ideally should match. There is a difference
in nano seconds.
Cause:
When touch is used modify atime or mtime to current time (UTIME_NOW),
the current time is taken from kernel. The ctime gets updated to current
time when atime or mtime is updated. But the current time to update
ctime is taken from utime xlator. Hence the difference in nano seconds.
Fix:
When utimesat uses UTIME_NOW, use the current time from kernel.

on rhel8 machine cleanup of shards is not happening properly for a
sharded file with hard-links. It needs to refresh the hard link count
to make it successful
The problem occurs when a sharded file with hard-links gets removed.
When the last link file is removed, all shards need to be cleaned up.
But in the current code structure shard xlator, instead of sending a lookup
to get the link count uses stale cache values of inodectx. Therby removing
the base shard but not the shards present in /.shard directory.
This fix will make sure that it marks in the first unlink's callback that
the inode ctx needs a refresh so that in the next operation, it will be
refreshed by looking up the file on-disk.

squash tens of warnings on padding of structs in afr structures.
The warnings were found by manually added '-Wpadded' to the GCC

Also made relevant structs and definitions static, where it
was applicable.

In many places we use it, compare to it, etc. It could be a static variable,
as it really doesn't change. I think it's better than initializing to 0
and then doing gfid[15] = 1 or other tricks.
I think there are additional oppportunuties to make more variables static.
This is an attempt at an easy one.

Ever since we added quorum checks for lookups in afr via commit
bd44d59741bb8c0f5d7a62c5b1094179dd0ce8a4, the split-brain resolution
commands would not work for replica 3 because there would be no
readables for the lookup fop.
The argument was that split-brains do not occur in replica 3 but we do
see (data/metadata) split-brain cases once in a while which indicate that there are
a few bugs/corner cases yet to be discovered and fixed.
Fortunately, commit 8016d51a3bbd410b0b927ed66be50a09574b7982 added
GF_CLIENT_PID_GLFS_HEALD as the pid for all fops made by glfsheal. If we
leverage this and allow lookups in afr when pid is GF_CLIENT_PID_GLFS_HEALD,
split-brain resolution commands will work for replica 3 volumes too.
Likewise, the check is added in shard_lookup as well to permit resolving
split-brains by specifying "/.shard/shard-file.xx" as the file name
(which previously used to fail with EPERM).

On systems that don't support "timespec_get"(e.g., centos6), it
was using "clock_gettime" with "CLOCK_MONOTONIC" to get unix epoch
time which is incorrect. This patch introduces "timespec_now_realtime"
which uses "clock_gettime" with "CLOCK_REALTIME" which fixes
the issue.

Null character string is a valid xattr value in file system. But for
those xattrs processed by md-cache, it does not update its entries if
value is null('\0'). This results in ENODATA when those xattrs are
queried afterwards via getxattr() causing failures in basic operations
like create, copy etc in a specially configured Samba setup for Mac OS
clients.
On the other side snapview-server is internally setting empty string("")
as value for xattrs received as part of listxattr() and are not intended
to be cached. Therefore we try to maintain that behaviour using an
additional dictionary key to prevent updation of entries in getxattr()
and fgetxattr() callbacks in md-cache.

To convert the existing `gf_msg` to `gf_smsg`:
- Define `_STR` of respective Message ID as below(In `*-messages.h`)
#define PC_MSG_REMOTE_OP_FAILED_STR "remote operation failed."
- Change `gf_msg` to use `gf_smsg`. Convert values into fields and
add any missing fields. Note: `errno` and `error` fields will be
added automatically to log message in case errnum is specified.
Example:
gf_smsg(
this->name, // Name or log domain
GF_LOG_WARNING, // Log Level
rsp.op_errno, // Error number
PC_MSG_REMOTE_OP_FAILED, // Message ID
"path=%s", local->loc.path, // Key Value 1
"gfid=%s", loc_gfid_utoa(&local->loc), // Key Value 2
NULL // Log End
);
Key value pairs formatting Help:
gf_slog(
this->name, // Name or log domain
GF_LOG_WARNING, // Log Level
rsp.op_errno, // Error number
PC_MSG_REMOTE_OP_FAILED, // Message ID
"op=CREATE", // Static Key and Value
"path=%s", local->loc.path, // Format for Value
"brick-%d-status=%s", brkidx, brkstatus, // Use format for key and val
NULL // Log End
);

In the libgfapi it will call glfs_poller() --> event_dispatch()
in file api/src/glfs.c:721, and the event_dispatch() is defined
by libgluster locally, the problem is the name of event_dispatch()
is the extremly the same with the one from libevent package form
the OS.
For example, if a executable program Foo, which will also use and
link the libevent and the libgfapi at the same time, I can hit the
crash, like:

00007feeeaffce30 error 4 in libevent-2.0.so.5.1.9[7fef006ed000+46000]
The link for Foo is:
lib_foo_LADD = -levent $(GFAPI_LIBS)
It will crash.
This is because the glfs_poller() is calling the event_dispatch() from
the libevent, not the libglsuter.
The gfapi link info :
GFAPI_LIBS = -lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid
If I link Foo like:
lib_foo_LADD = $(GFAPI_LIBS) -levent
It will works well without any problem.
And if Foo call one private lib, such as handler_glfs.so, and the
handler_glfs.so will link the GFAPI_LIBS directly, while the Foo won't
and it will dlopen(handler_glfs.so), then the crash will be hit everytime.
The link info will be:
foo_LADD = -levent
libhandler_glfs_LIBADD = $(GFAPI_LIBS)
I can avoid the crash temporarily by linking the GFAPI_LIBS in Foo too like:
foo_LADD = $(GFAPI_LIBS) -levent
libhandler_glfs_LIBADD = $(GFAPI_LIBS)
But this is ugly since the Foo won't use any APIs from the GFAPI_LIBS.
And in some cases when the --as-needed link option is added(on many dists
it is added as default), then the crash is back again, the above workaround
won't work.

Problem:
When frame->local is not null FRAME_DESTROY calls mem_put on it.
Since the stub is already destroyed in call_resume(), it leads
to crash
Fix:
Set frame->local to NULL before calling call_resume()

Problem:
The files which were created before ctime enabled would not
have "trusted.glusterfs.mdata"(stores time attributes) xattr.
Upon fops which modifies either ctime or mtime, the xattr
gets created with latest ctime, mtime and atime, which is
incorrect. It should update only the corresponding time
attribute and rest from backend
Solution:
Creating xattr with values from brick is not possible as
each brick of replica set would have different times.
So create the xattr upon successful lookup if the xattr
is not created
Note To Reviewers:
The time attributes used to set xattr is got from successful
lookup. Instead of sending the whole iatt over the wire via
setxattr, a structure called mdata_iatt is sent. The mdata_iatt
contains only time attributes.

snapview server xlator makes use of "localhost" as the volfile server while
initing the new glfs instance to talk to a snapshot. While localhost is fine,
better use the same volfile server that was used to start the snapshot
daemon containing the snapview-server xlator.

glusterfs-fops.h was moved to rpc/xdr to support compound fops.
(ref: https://review.gluster.org/14032, 2f945b86d3)
This was fine as long as all these header files were in single
include directory after 'install'. With the move to separate out
glusterfs specific header files into another directory inside
/usr/include (ref: https://review.gluster.org/21746, 20ef211cfa),
glusterfs-fops.h file was not in the proper path when an external
.c file tried to include any of glusterfs specific .h file (like
xlator.h).
Now, we have removed compound-fops, with that, none of the enums
declared in glusterfs-fops.h are actually getting used on wire
anymore. Hence, it makes sense to get this to libglusterfs/src
as a single point of definition. With this change, the external
programs can use glusterfs header files.
also remove some enum definitions which are not used in code
anymore.

We were cleaning xlator from botton to top, which might
lead to problems when upper xlators trying to access
the xlator object loaded below.
One such scenario is when fd_unref happens as part of the
fini call which might lead to calling the releasedir to
lower xlator. This will lead to invalid mem access

We were using glusterfs_graph_fini to free the xl rec from
glusterfs_process_volfp as well as glusterfs_graph_cleanup.
Instead we can use glusterfs_graph_deactivate, which is does
fini as well as other common rec free.
