while creating rpc_tranpsort object, we store a dictionary without
taking a ref on dict but it does an unref during the cleaning of the
transport object.
So the rpc layer expect the caller to take a ref on the dictionary
before passing dict to rpc layer. This leads to a lot of confusion
across the code base and leads to ref leaks.
Semantically, this is not correct. It is the rpc layer responsibility
to take a ref when storing it, and free during the cleanup.
I'm listing down the total issues or leaks across the code base because
of this confusion. These issues are currently present in the upstream
master.
1) changelog_rpc_client_init
2) quota_enforcer_init
3) rpcsvc_create_listeners : when there are two transport, like tcp,rdma.
4) quotad_aggregator_init
5) glusterd: init
6) nfs3_init_state
7) server: init
8) client:init
This patch does the cleanup according to the semantics.

`address_family=inet6` needs to be added while mounting master and
slave volumes in gverify script.
New option introduced to gluster cli(`--inet6`) which will be used
internally by geo-rep while calling `gluster volume info
--remote-host=<ipv6>`.

nr_files is supposed to represent the number of files opened in posix.
Present logic doesn't seem to handle anon-fds because of which the
counts would always be wrong.
I don't remember anyone using this value in debugging any problem probably
because we always have 'ls -l /proc/<pid>/fd' which not only prints the
fds that are active but also prints their paths. It also handles directories
and anon-fds which actually opened the file. So removing this code
instead of fixing the buggy logic to have the nr_files.

Before going into the lock, verify stub_cnt != 0.
Otherwise, let's skip this code.
Unrelated, switch a CALLOC to MALLOC, as we
initialize all members right away. This allocation
is done also under lock, so also should help a bit.

Problem:
In an arbiter volume configuration SHD will not send any writes onto the arbiter
brick even if there is data pending marker for the arbiter brick. If we have a
arbiter setup on the geo-rep master and there are data pending markers for the files
on arbiter brick, SHD will not mark any data changelog during healing. While syncing
the data from master to slave, if the arbiter-brick is considered as ACTIVE, then
there is a chance that slave will miss out some data. If the arbiter brick is being
newly added or replaced there is a chance of slave missing all the data during sync.
Fix:
If there is data pending marker for the arbiter brick, send truncate on the arbiter
brick during heal, so that it will record truncate as the data transaction in changelog.

Discussion on thin arbiter volume -
https://github.com/gluster/glusterfs/issues/352#issuecomment-350981148
Main idea of having this rpm package is to deploy thin-arbiter
without glusterd and other commands on a node, and all we need
on that tie-breaker node is to run a single glusterfs command.
Also note that, no other glusterfs installation needs
thin-arbiter.so.
Make sure RPM contains sample vol file, which can work by default,
and a script to configure that volfile, along with translator image.

Problem:
Currently even if open & opendir fails on quorum number of bricks,
but succeeds on atleast one brick, it will result in success. This leads
to inconsistency in the behaviour with other operations following the
open, which has quorum checks.
Fix:
Add quorum checks to open & opendir fops to avoid inconsistency.

This deadlock happens while processing dentry corresponding to current
directory (.) in rda_fill_readdirp. In this case following order is
followed:
LOCK(directory_fd_ctx->lock);
rda_inode_ctx_get_iatt -> LOCK(directory_inode->lock);
However, in rda_mark_inode_dirty following lock order is followed:
LOCK(directory_inode->lock);
LOCK(directory_fd_ctx->lock);
these two codepaths when executed concurrently resulted in a deadlock.
Current patch fixes this by removing locking directory inode and
fd-ctx in rda_fill_readdirp. This is fine as directory inode's stat
won't change due to writes to files within directory.

The structs worm_reten_state_t and read_only_priv_t from read-only.h are
using uint64_t values to store periods of retention and autocommmit.
This seems to be dangerous since in worm-helper.c the function
worm_set_state computes in line 97:
stbuf->ia_atime = time(NULL) + retention_state->ret_period;
stbuf->ia_atime is using int64_t because of the settings of struct
iattr. So if there is a very very high retention period stored, there
is maybe an integer overflow.
What can be the solution? Using int64_t instead if uint64_t may reduce
the probability of the occurance.

Problem: commit 5a152a changed the mechansim of computing the
checksum. In heterogeneous cluster, peers are running into
rejected state because we have different cksum computation
mechansims in upgraded and non-upgraded nodes.
Solution: add a check for op-version so that all the nodes
in the cluster follow the same mechanism for computing the
cksum.

fops marked internal are used to maintain data integrity
and ideally do not intervene with application client leases.
Hence it seems safe to ignore them by lease xlator.

There was 30% regression observed in mkdir path with commit
b139bc58eb504adf5ef81658896c9283ae21f390. On analysis it is found
that io-threads xlator deprioritzes fops with all -ve pid.
Some context in to the no-root-squash pid requirement:
DHT xlator does some of the internal fops with root privileges. This is
needed so that operations like layout healing should not be abandoned
because a non root user is operating. If root-squash option is enabled
the layout set operation looses its root privilege as server xlator
converts the uid and pid to random numbers. Hence, the above mentioned
commit converted pid to GF_CLIENT_PID_NO_ROOT_SQUASH to continue fops
as root.
Combining the above I am proposing not to deprioritize fops with
no-root-squash pid.

[glusterfs3.h:752:dict_to_xdr] 0-dict: key 'volume-uuid' is not sent on wire [Invalid argument]
For quota, there is a deamon named quotad which has a rpcsvc_program
quotad_aggregator_prog that only supports v3 right now.
Quotad has two actors (LOOKUP,GETLIMIT) that contains a dict in request,
quotad just decodes the dict by dict_unserialize, those dict dates's type
is GF_DATA_TYPE_STR_OLD, which type is not supported at glusterfs v4.

The "struct iatt" in iatt.h is using int64_t types for storing
the atime, mtime and ctime. Therefore the struct 'struct md_cache' in
md-cache.c should also use this types to avoid an integer overflow.
This can happen e.g. if someone uses a very high default-retention-period
in the WORM-Xlator.

Two issues were found:
1. in wb_readdirp_cbk, inode should unrefed after wb_inode is
unlocked. Otherwise, inode and hence the context wb_inode can be freed
by the type we try to unlock wb_inode
2. wb_readdirp_mark_end iterates over a list of wb_inodes of children
of a directory. But inodes could've been freed and hence the list
might be corrupted. To fix take a reference on inode before adding it
to invalidate_list of parent.

This patch implements a thread pool that is wait-free for adding jobs to
the queue and uses a very small locked region to get jobs. This makes it
possible to decrease contention drastically. It's based on wfcqueue
structure provided by urcu library.
It automatically enables more threads when load demands it, and stops
them when not needed. There's a maximum number of threads that can be
used. This value can be configured.
Depending on the workload, the maximum number of threads plays an
important role. So it needs to be configured for optimal performance.
Currently the thread pool doesn't self adjust the maximum for the
workload, so this configuration needs to be changed manually.
For this reason, the global thread pool has been made optional, so that
volumes can still use the thread pool provided by io-threads.
To enable it for bricks, the following option needs to be set:
config.global-threading = on
This option has no effect if bricks are already running. A restart is
required to activate it. It's recommended to also enable the following
option when running bricks with the global thread pool:
performance.iot-pass-through = on
To enable it for a FUSE mount point, the option '--global-threading'
must be added to the mount command. To change it, an umount and remount
is needed. It's recommended to disable the following option when using
global threading on a mount point:
performance.client-io-threads = off
To enable it for services managed by glusterd, glusterd needs to be
started with option '--global-threading'. In this case all daemons, like
self-heal, will be using the global thread pool.
Currently it can only be enabled for bricks, FUSE mounts and glusterd
services.
The maximum number of threads for clients and bricks can be configured
using the following options:
config.client-threads
config.brick-threads
These options can be applied online and its effect is immediate most of
the times. If one of them is set to 0, the maximum number of threads
will be calcutated as #cores * 2.
Some distributions use a very old userspace-rcu library (version 0.7)
for this reason, some header files from version 0.10 have been copied
into contrib/userspace-rcu and are used if the detected version is 0.7
or older.
An additional change has been made to io-threads to prevent that threads
are started when iot-pass-through is set.

posix converts incoming operations on files to operations on
corresponding gfid handles. While this in itself is not a problem,
logging of those gfid handles in place of actual file paths can
create confusions during debugging. The best way would be to
print both the actual file (recieved as an argument) for path
based operations and the gfid handle associated with it.

If parallel-readdir is enabled, the rda xlator is loaded
below dht in the graph and proactively lists and caches
entries when an opendir is performed. dht_rmdir checks if
the directory being deleted contains stale linkto files by
performing a readdirp on its child subvols. However, as
the entries are actually read in during the opendir operation
which does not request the linkto xattr,no linkto xattrs are
present for the entries causing dht to incorrectly identify
them as data files and fail the rmdir operation with ENOTEMPTY.
DHT now always adds the linkto xattr in the list of xattrs
requested in the opendir.

The loc_wipe is done in the _out_ section, inode_unref(loc.parent) here
casues a double extra unref of loc.parent.

A race between the lookup selfheal and rmdir can cause
directories to be healed only on non-hashed subvols.
This can prevent the directory from being listed from
the mount point and in turn causes rm -rf to fail with
ENOTEMPTY.
Fix: Update the layout information correctly and reduce
the call count only after processing the response.

We were not properly cleaning self-heal daemon resources
during afr fini. This patch will clean the same.

During disconnect cleanup, we are not cancelling reconnect
timer, which causes a ref leak each time when a disconnect

Explicit invalidation by calling inode_invalidate is necessary when
same (meta)data is shared/access across multiple mounts. Without an
explicit inode_invalidate call, caches in the mount which didn't
witness writes wouldn't be aware of changes as writes wouldn't have
passed through them. However, if (meta)data is not shared, all
relevant I/O goes through the cache of single mount and hence is
coherent with (meta)data on bricks always. So, explicit inode
invalidation can be disabled for this case which gives a huge
performance boost for workloads that write data and then immediately
read the data they just wrote. Note that otherwise, local writes
(which pass through the cache) will change ctime and cause unnecessary
invalidations.
The name of the option that controls this behavior is
"performance.global-cache-invalidation". This option is global and it
purges caches both in glusterfs and kernel stack for native FUSE
mounts. For non-native FUSE mounts, it purges cache only from
glusterfs stack. This option is effective only when
performance.stat-prefetch is on.
Note that there is a similar option "performance.cache-invalidation",
but the scope of that option is limited to quick-read and md-cache.

When "auto-invalidation" option was not specified for mount script,
glusterfs cmdline ended with "--auto-invalidation=" option. This patch
fixes that bug in mount script.
Thanks to Amar for reporting it.

The setxattr function receives a pointer to raw data, which may not be
null-terminated. When this data needs to be interpreted as a string, an
explicit null termination needs to be added before using the value.

Problem: get-state command will error out, if any of the underlying
brick(s) of volume(s) in the cluster go bad.
It is expected that get-state command should not error out, but
should generate an output successfully.
Solution: In glusterd_get_state(), a statfs call is made on the
brick path for every bricks of the volumes to calculate the total
and free memory available. If any of statfs call fails on any
brick, we should not error out and should report total memory and free
memory of that brick as 0.
This patch also handles a statfs failure scenario in
glusterd_store_retrieve_bricks().

Scenarios tested:
* Upgrade the node when there are stripe / tiering and regular
type of volumes are present.
- All volumes are started fine (as the change was not on brick volfile)
- For tier, the functionality may not even work, as changetimerecorder
is not present.
- 'gluster volume info' properly shows as 'NOT SUPPORTED' for stripe and
tier type of volume.
* Upgrade in a rolling upgrade scenario, where an old version is
able to connect to higher master.
- on a normal volume, if the volfile-server was new, the newer client
volfiles needed to have utime xlator conditionally.
- with this one change, all other changes seem to work fine.
