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.

Currently Gluster keeps process pid information of all the daemons
and brick processes in Gluster configuration file directory
(ie., /var/lib/glusterd/*).
These pid files should be seperate from configuration files.
Deletion of the configuration file directory might result into serious problems.
Also, /var/run/gluster is the default placeholder directory for pid files.
So, with this fix Gluster will keep all process pid information of all
processes in /var/run/gluster/* directory.

Problem: Since rename didn't check if newloc exists and it's
retention state it was possible to rename a new file that wasn't
in retention over a existing file that was in read-only state.

xattrs may very well contain binary, non-text data with leading 0
values. Using strcmp for checking empty values is not the appropriate
thing to do: In the best case, it might treat a binary xattr value
starting with 0 from being cached (and hence also from being reported
back with xattr). In the worst case, we might read beyond the end
of a data blob that does contain any zero byte.
We fix this by checking the length of the data blob and checking
the first byte against 0 if the length is one.

We need a provision to be able to set lkowner (which is
used to distinguish locks maintained by server) in gfapi.
Since the same lk_owner need to be used to be able to
flush the lock while closing the fd, store the lkowner
in the glfd structure itself.
A new API has been added to be able to set lkowner in glfd.
This is backport of below mainline fix -

This is because having it disabled seems to improve performance.
This could be due to the lock contention by the different epoll threads
on the circular buff lock in the fop cbks just before writing their response
to /dev/fuse.
Just to provide some data - wrt ovirt-gluster hyperconverged
environment, I saw an increase in IOPs by 12K with event-history
disabled for randrom read workload.
Usage:
mount -t glusterfs -o event-history=on $HOSTNAME:$VOLNAME $MOUNTPOINT
OR
glusterfs --event-history=on --volfile-server=$HOSTNAME --volfile-id=$VOLNAME $MOUNTPOINT

Problems:
As described in BZ 1491670, renaming hardlinks can result in data/mdata
split-brain of the DHT link-to files (T files) without any mismatch of
data and metadata.
As described in BZ 1486063, for a zero-byte file with only dirty bits
set, arbiter brick will likely be chosen as the source brick.
Fix:
For zero byte files in split-brain, pick first brick as
a) data source if file size is zero on all bricks.
b) metadata source if metadata is the same on all bricks
In arbiter case, if file size is zero on all bricks and there are no
pending afr xattrs, pick 1st brick as data source.

Current rebalance throttle options: lazy/normal/aggressive may not always be
sufficient for the purpose of throttling. In our recent test, we observed for
certain setups, normal and aggressive modes behaved similarly consuming full
disk bandwidth. So in cases like this admin should be able to tune it
down(or vice versa) depending on the need.
Along with old throttle configurations, thread counts are tuned based on number.
e.g. gluster v set vol-name cluster-rebal.throttle 5.
Admin can tune up/down between 0 and the number of cores available.
Note: For heterogenous servers, validation will fail on the old server if "number"
is given for throttle configuration.
The message looks something like this:
"volume set: failed: Staging failed on vm2. Error: cluster.rebal-throttle should be {lazy|normal|aggressive}"
Test: Manual test by logging active thread number after reconfiguring throttle option.
testcase: tests/basic/distribute/throttle-rebal.t

Problem:
In a 3 way replica, when the source brick does not have pending xattrs
for the sinks, but the 2 sinks blame each other, metadata heal was not
happpening because we were not setting all non-sources as sinks.
Fix: Mark all non-sources as sinks, like it is done in data and entry
heal.

using some offsets greater than the end of file returned successfully

Eg. sysctl net.ipv4.ip_local_reserved_ports="49152-49156"
In above case glusterd crashes while parsing the port.
With this fix glusterd will be able to handle port range
between INT_MIN to INT_MAX

With brick multiplexing enabled, upon a node reboot new bricks were
not being attached to the first spawned brick process even though
there wasn't any compatibility issues.
The reason for this is that upon glusterd restart after a node
reboot, since brick services aren't running, glusterd starts the
bricks in a "no-wait" mode. So after a brick process is spawned for
the first brick, there isn't enough time for the corresponding pid
file to get populated with a value before the compatibilty check is
made for the next brick.
This commit solves this by iteratively waiting for the pidfile to be
populated in the brick compatibility comparison stage before checking
if the brick process is alive.

Problem:
Rebalance compares the node-uuid of a file against its own
to and migrates a file only if they match. However, the
current behaviour in both AFR and EC is to return
the node-uuid of the first brick in a replica set for all
files. This means a single node ends up migrating all
the files if the first brick of every replica set is on the
same node.
Fix:
AFR and EC will return all node-uuids for the replica set.
The rebalance process will divide the files to be migrated
among all the nodes by hashing the gfid of the file and
using that value to select a node to perform the migration.
This patch makes the required DHT and tiering changes.
Some tests in rebal-all-nodes-migrate.t will need to be
uncommented once the AFR and EC changes are merged.

The aux mount is created on the first limit/remove_limit/list command
and it remains until volume is stopped / deleted / (quota is disabled)
, where we do a lazy unmount. If the process is uncleanly terminated,
then the mount entry remains and we get (Transport disconnected) error
on subsequent attempts to run quota list/limit-usage/remove commands.
Second issue, There is also a risk of inadvertent rm -rf on the
/var/run/gluster causing data loss for the user. Ideally, /var/run is
a temp path for application use and should not cause any data loss to
persistent storage.
Solution:
1) unmount the aux mount after each use.
2) clean stale mount before mounting, if any.
One caveat with doing mount/unmount on each command is that we cannot
use same mount point for both list and limit commands.
The reason for this is that list command needs mount to be accessible
in cli after response from glusterd, So it could be unmounted by a
limit command if executed in parallel (had we used same mount point)
Hence we use separate mount points for list and limit commands.

Reset brick currently kills of the corresponding brick process.
However, with brick multiplexing enabled, stopping the brick
process would render all bricks attached to it unavailable. To
handle this correctly, we need to make sure that the brick process
is terminated only if brick-multiplexing is disabled. Otherwise,
we should send the GLUSTERD_BRICK_TERMINATE rpc to the respective
brick process to detach the brick that is to be reset.

Problem: While brick-muliplexing is on after restarting glusterd, CLI is
not showing pid of all brick processes in all volumes.
Solution: While brick-mux is on all local brick process communicated through one
UNIX socket but as per current code (glusterd_brick_start) it is trying
to communicate with separate UNIX socket for each volume which is populated
based on brick-name and vol-name.Because of multiplexing design only one
UNIX socket is opened so it is throwing poller error and not able to
fetch correct status of brick process through cli process.
To resolve the problem write a new function glusterd_set_socket_filepath_for_mux
that will call by glusterd_brick_start to validate about the existence of socketpath.
To avoid the continuous EPOLLERR erros in logs update socket_connect code.
Test: To reproduce the issue followed below steps
1) Create two distributed volumes(dist1 and dist2)
2) Set cluster.brick-multiplex is on
3) kill glusterd
4) run command gluster v status
After apply the patch it shows correct pid for all volumes

The test files that were marked as bad test were checked and
updated for centos. The tests that had issue were fixed.
Tests that aren't needed anymore are removed.
REASON:
tests/basic/tier/tier-file-create.t
This test checks one line after creating a tiered volume (which
is done in every tier test). So this line is moved along with
other test in tier and the file is deleted.
tests/bugs/tier/bug-1286974.t
This bug checks for the tier as a task and tier has been moved
from a task to service as a part of the tier as a service patch
https://review.gluster.org/#/c/13365/
So it is removed from bad tests.
tests/basic/tier/record-metadata-heat.t
This test had a bug and has been fixed.
tests/basic/tier/bug-1214222-directories_missing_after_attach_tier.t
tests/basic/tier/fops-during-migration.t
tests/basic/tier/tier-snapshot.t
tests/basic/tier/tier_lookup_heal.t
These test seem to work fine on centos now.

bug-1421590-brick-mux-reuse-ports.t seems to be a bad test to me and here is my
reasoning:
This test tries to check if the ports are reused or not. When a volume is
restarted, by the time glusterd tries to allocate a new port to the one of the
brick processes of the volume there is no guarantee that the older port will be
allocated given the kernel might take some extra time to free up the port between
this time frame. From
https://build.gluster.org/job/regression-test-burn-in/2932/console we can
clearly see that post restart of the volume, glusterd allocated port 49153 &
49155 for brick1 & brick2 respectively but the test was expecting the ports to
be matched with 49155 & 49156 which were allocated before the volume was
restarted.

Problem:
In afr-v2, self-blaming xattrs are not there by design. But if the FOP
failed on a brick due to an error other than ENOTCONN (or even due to
ENOTCONN, but we regained connection before postop was wound), we wind
the post-op also on the failed brick, leading to setting self-blaming
xattrs on that brick. This can lead to undesired results like healing of
files in split-brain etc.
Fix:
If a fop failed on a brick on which pre-op was successful, do not
perform post-op on it. This also produces the desired effect of not
resetting the dirty xattr on the brick, which is how it should be
because if the fop failed on a brick, there is no reason to clear the
dirty bit which actually serves as an indication of the failure.

We need to do this because modifying the volume/brick tree while
glusterd_restart_bricks is still walking it can lead to segfaults.
Without waiting we could accidentally "slip in" while attach_brick has
released big_lock between retries and make such a modification.

One of the brick multiplexing patches (commit 1a95fc3) had some changes
in gf_auth () & server_setvolume () functions which caused auth-allow
feature to be broken. mount doesn't succeed even if it's part of the
auth-allow list. This fix does the following:
1. Reintroduce the peer-info data back in gf_auth () so that fnmatch has
valid input and it can decide on the result.
2. config-params dict should capture key values pairs for all the bricks
in case brick multiplexing is on. In case brick multiplexing isn't
enabled, then config-params should carry attributes from protocol/server
such that all rpc auth related attributes stay in tact in the
dictionary.

Problem:
While doing conservative merge, even if a brick is down, it will reset
the pending xattr on that. When that brick comes up, as part of the
heal, it will consider this brick as the source and removes the entries
on the other bricks, which leads to data loss.
Fix:
Undo pending only for the bricks which are up.

Commit 086436a introduced generation number (cleanup_gen) to ensure that
rpc layer doesn't end up cleaning up the connection object if
application layer has already destroyed it. Bumping up cleanup_gen was
done only in rpc_clnt_connection_cleanup (). However the same is needed
in rpc_clnt_reconnect_cleanup () too as with out it if the object gets destroyed
through the reconnect event in the application layer, rpc layer will
still end up in trying to delete the object resulting into double free
and crash.
Peer probing an invalid host/IP was the basic test to catch this issue.

Failure to do this could lead to a race in which a timer would be
removed twice concurrently, corrupting the timer list (because
gf_timer_call_cancel has no internal protection against this) and
possibly causing a crash.

Problem: add-brick command to increase replica count in an arbiter
volume succeeds, causing undesirable effects like the 4th brick being
loaded with the arbiter xlator, the 3rd one losing the arbiter xlator
(when the brick process is restarted), arbitration logic in afr going
for a toss etc.
Fix: Arbiter configuration should always be a replica 3 volume (of
which 3rd brick is arbiter). Hence disallow increasing replica count for
arbiter volume configurations.

This commit changes the following:
1. In glusterfs_handle_terminate, send out individual pmap signout
requests to glusterd for every brick.
2. Add another parameter to glusterfs_mgmt_pmap_signout function to
pass the brickname that needs to be removed from the pmap registry.
3. Make sure pmap_registry_search doesn't break out from the loop
iterating over the list of bricks per port if the first brick entry
corresponding to a port is whitespaced out.
4. Make sure the pmap registry entries are removed for other
daemons like snapd.

Problem-1
If Lookup which doesn't take any locks observes version mismatch it can't be
trusted. If we launch a heal based on this information it will lead to
self-heals which will affect I/O performance in the cases where Lookup is
wrong. Considering self-heal-daemon and operations on the inode from client
which take locks can still trigger heal we can choose to not attempt a heal on
Lookup.
Problem-2:
Fixed spurious failure of
tests/bitrot/bug-1373520.t
For the issues above, what was happening was that ec_heal_inspect()
is preventing 'name' heal to happen
Problem-3:
tests/basic/ec/ec-background-heals.t
To be honest I don't know what the problem was, while fixing
the 2 problems above, I made some changes to ec_heal_inspect() and
ec_need_heal() after which when I tried to recreate the spurious
failure it just didn't happen even after a long time.

On recieving a rename fop, marker_rename() stores the,
oldloc and newloc in its 'local' struct, once the rename
is done, the xtime marker(last updated time) is set on
the file, but sending a setxattr fop. When upcall
receives the setxattr fop, the loc->inode is NULL and
it crashes. The loc->inode can be NULL only in one valid
case, i.e. in rename case where the inode of new loc
can be NULL. Hence, marker should have filled the inode
of the new_loc before issuing a setxattr.
marker_rename_cbk was already fixed in a previous commit.
Fixing marker_rename_done to send valid inode in this commit.
Also in upcall check for NULL inode so that there is no crash.

Problem:
The various split-brain resolution policies (favorite-child-policy based,
CLI based and mount (get/setfattr) based) attempt to resolve split-brain
even when not all bricks of replica are up. This can be a problem when
say in a replica 3, the only good copy is down and the other 2 bricks
are up and blame each other (i.e. split-brain). We end up healing the
file in such a case and allow I/O on it.
Fix:
A decision on whether the file is in split-brain or not must be taken
only if we are able to examine the afr xattrs of *all* bricks of a given
replica.

When GlusterD sends the STATEDUMP procedure to the libgfapi client, the
client checks if it matches the PID that should take the statedump. If
so, it will do a statedump for the glfs_t that is connected to this mgmt
connection.

Introduce glfs_sysrq() as a generic API for triggering debug and
troubleshoot events. This interface will be used by the feature to get
statedumps for applications using libgfapi.
The current events that can be requested through this API are:
- 'h'elp: log a mesage with all supported events
- 's'tatedump: trigger a statedump for the passed glfs_t
In future, this API can be used by a CLI to trigger statedumps from
storage servers. At the moment it is limited to take statedumps, but it
is extensible to set the log-level, clear caches, force reconnects and
much more.

With this, we will be able to trigger statedumps on remote Gluster
clients, mainly targetted for applications using libgfapi.
Design:
SIGUSR signal is the most comman way of taking a statedump in Gluster.
But it cannot be used for libgfapi based processes, as the process
loading the library might have already consumed SIGUSR signal. Hence
going by the command way.
One has to issue a Gluster command to initiate a statedump on the
libgfapi based client. The command takes hostname and PID as an
argument. All the glusterds in the cluster, check if they are connected
to the specified hostname, and send an RPC request to all the connected
clients from that hostname (via the mgmt connection).

The problem here is that a volume's transport options can change, but
any snapshots' bricks don't follow along even though they're now
incompatible (with respect to multiplexing). This was causing the
USS+SSL test to fail. By keeping the snapshot bricks separate
(though still potentially multiplexed with other snapshot bricks
including those for other volumes) we can ensure that they remain
unaffected by changes to their parent volumes.
Also fixed various issues with how the test waits (or more precisely
didn't) for various events to complete before it continues.

With multiplexing, the trash translator gets a reconfigure call before
a notify(CHILD_UP). In this case, priv->trash_itable was not yet
initialized, so the reconfigure would get a SEGV. Moving the itable
allocation to init seems to fix it, so trash can be reenabled.

When GlusterD is restarted on a multi node cluster, while syncing the
global options from other GlusterD, it checks for quorum and based on
which it decides whether to stop/start a brick. However we handle the
return code of this function in which case if we don't want to start any
bricks the ret will be non zero and we will end up failing the import
which is incorrect.
Fix is just to ignore the ret code of glusterd_restart_bricks ()

The number of brick processes no longer matches the number of bricks,
therefore counting processes doesn't work. Counting *pidfiles* does.
Ironically, the fix broke multiplex.t which used this function, so it
now uses a different function with the old process-counting behavior.
Also had to fix online_brick_count and kill_node in cluster.rc to be
consistent with the new reality.

The 2 tests that were marked bad in master are,
tests/basic/ec/ec-background-heals.t
tests/bitrot/bug-1373520.t
The same are marked bad in release-3.10 to prevent any spurious
failures during backporting other commits.
When the failures are analyzed and fixed in master the same would
need to be backported, as applicable, to release-3.10 branch.

To enable the integration of md-cache and invalidation features
we need to perform 3 volume set options in a specific order.
In order to ease this for user provide a group volume set option.
Usage: gluster vol set <VOLNAME> group metadata-cache

Same problem as https://review.gluster.org/#/c/16509/ in a different
place. Tests detach bricks without glusterd's knowledge, so
glusterd's internal brick state is out of date and we have to re-check
(via the brick's pidfile) as well.

The system actually handles this OK, but with multiplexing the result
of killing the whole process is not what some tests assumed.

Early multiplexing tests revealed *massive* contention on certain
pools' global locks - especially for dictionaries and secondarily for
call stubs. For the thread counts that multiplexing can create, a
more lock-free solution is clearly needed. Also, the current mem-pool
implementation does a poor job releasing memory back to the system,
artificially inflating memory usage to match whatever the worst case
was since the process started. This is bad in general, but especially
so for multiplexing where there are more pools and a major point of
the whole exercise is to reduce memory consumption.
The basic ideas for the new design are these
There is one pool, globally, for each power-of-two size range.
Every attempt to create a new pool within this range will instead
add a reference to the existing pool.
Instead of adding pools for each translator within each multiplexed
brick (potentially infinite and quite possibly thousands), we
allocate one set of size-based pools per *thread* (hundreds at
worst).
Each per-thread pool is divided into hot and cold lists. Every
allocation first attempts to use the hot list, then the cold list.
When objects are freed, they always go on the hot list.
There is one global "pool sweeper" thread, which periodically
reclaims everything in each pool's cold list and then "demotes" the
current hot list to be the new cold list.
For normal allocation activity, only a per-thread lock need be
taken, and even that only to guard against very rare contention from
the pool sweeper. When threads start and stop, a global lock must
be taken to add them to the pool sweeper's list. Lock contention is
therefore extremely low, and the hot/cold lists also provide good
locality.
A more complete explanation (of a similar earlier design) can be found
here:

This patch adds support for multiple brick translator stacks running in
a single brick server process. This reduces our per-brick memory usage
by approximately 3x, and our appetite for TCP ports even more. It also
creates potential to avoid process/thread thrashing, and to improve QoS
by scheduling more carefully across the bricks, but realizing that
potential will require further work.
Multiplexing is controlled by the "cluster.brick-multiplex" global
option. By default it's off, and bricks are started in separate
processes as before. If multiplexing is enabled, then *compatible*
bricks (mostly those with the same transport options) will be started in
the same process.
