+Subject: [PATCH 03/52] rpc: set bind-insecure to off by default
+
+commit 243a5b429f225acb8e7132264fe0a0835ff013d5 turn's 'ON'
+allow-insecure and bind-insecure by default.
+
+Problem:
+Now with newer versions we have bind-insecure 'ON' by default.
+So, while upgrading subset of nodes from a trusted storage pool,
+nodes which have older versions of glusterfs will expect
+connection from secure ports only (since they still have
+bind-insecure off) thus they reject connection from upgraded
+nodes which now have insecure ports.
+
+Hence we will run into connection issues between peers.
+
+Solution:
+This patch will turn bind-insecure 'OFF' by default to avoid
+problem explained above.

+Subject: [PATCH 04/52] glusterd/spec: fixing autogen issue
+
+Backport of https://code.engineering.redhat.com/gerrit/#/c/59463/
+
+Because of the incorrect build section, autogen.sh wasn't re-run during the rpm
+build process. The `extras/Makefile.in` was not regenerated with the changes
+made to `extras/Makefile.am` in the firewalld patch. This meant that
+`extras/Makefile` was generated without the firewalld changes. So the firewalld
+config wasn't installed during `make install` and rpmbuild later failed when it
+failed to find `/usr/lib/firewalld/glusterfs.xml`

+Subject: [PATCH 09/52] build: introduce security hardening flags in gluster
+
+This patch introduces two of the security hardening compiler flags RELRO & PIE
+in gluster codebase. Using _hardened_build as 1 doesn't guarantee the existance
+of these flags in the compilation as different versions of RHEL have different
+redhat-rpm-config macro. So the idea is to export these flags at spec file
+level.

+Subject: [PATCH 10/52] spec: fix/add pre-transaction scripts for geo-rep and
+ cli packages
+
+The cli subpackage never had a %pretrans script, this has been added
+now.
+
+The %pretrans script for ge-repliaction was never included in the RPM
+package because it was disable by a undefined macro (_can_georeplicate).
+This macro is not used/set anywhere else and _without_georeplication
+should take care of it anyway.
+
+Note: This is a Red Hat Gluster Storage specific patch. Upstream
+      packaging guidelines do not allow these kind of 'features'.

+-terms of features and extensibility.  It borrows a powerful concept
+-called Translators from GNU Hurd kernel. Much of the code in GlusterFS

+Subject: [PATCH 15/52] build: randomize temp file names in pretrans scriptlets
+
+Security issue CVE-2015-1795 mentions about possibility of file name
+spoof attack for the %pretrans server scriptlet.
+Since %pretrans scriptlets are executed only for server builds, we can
+use os.tmpname() to randomize temporary file names for all %pretrans
+scriptlets using this mechanism.

+Subject: [PATCH 16/52] glusterd, parallel-readdir: Change the op-version of
+ parallel-readdir to 31100
+
+Issue: Downstream 3.2 was released with op-version 31001, parallel-readdir
+feature in upstream was released in 3.10 and hence with op-version 31000.
+With this, parallel-readdir will be allowed in 3.2 cluster/clients as well.
+But 3.2 didn't have parallel-readdir feature backported.
+
+Fix:
+Increase the op-version of parallel-readdir feature only in downstream
+to 31100(3.3 highest op-version)

+Subject: [PATCH 34/52] glusterd: introduce a new op-version for rhgs-3.4.3
+
+This patch introduces a new op-version 31305 for rhgs-3.4.3 and
+sets the max op-version to 31305.
+
+For migrating profile commands (commit e68845ff7018e5d81d7979684b18e6eda449b088)
+we used GD_OP_VERSION_6_0 in upstream. we are changing
+it to GD_OP_VERSION_3_13_5 here.

+Subject: [PATCH 42/52] spec: (client|server) Builds are failing on rhel-6
+
+Problem: 1) For sever-rpm gluster build is throwing an error
+            undefined reference to `dlcose` on RHEL 6
+         2) For server-rpm build is throwing reference for

+            File Not found for all files with exclude
+            file in without_server check
+
+Solution: 1) For server-rpm add LIB_DL link in Makefile
+             and remove reference for rot.so and symlink-cache.so
+             from glusterfs.spec.in
+          2) Remove exclude files list as they are not
+             being build

+
+dumping the whole inode table detail to screen doesn't solve any
+purpose. We should be getting only toplevel details on CLI, and
+then if one wants to debug further, then they need to get to
+'statedump' to get full details.

+Subject: [PATCH 44/52] cluster/ec: Don't enqueue an entry if it is already
+ healing
+
+Problem:
+1 - heal-wait-qlength is by default 128. If shd is disabled
+and we need to heal files, client side heal is needed.
+If we access these files that will trigger the heal.
+However, it has been observed that a file will be enqueued
+multiple times in the heal wait queue, which in turn causes
+queue to be filled and prevent other files to be enqueued.
+
+2 - While a file is going through healing and a write fop from
+mount comes on that file, it sends write on all the bricks including
+healing one. At the end it updates version and size on all the
+bricks. However, it does not unset dirty flag on all the bricks,
+even if this write fop was successful on all the bricks.
+After healing completion this dirty flag remain set and never
+gets cleaned up if SHD is disabled.
+
+Solution:
+1 - If an entry is already in queue or going through heal process,
+don't enqueue next client side request to heal the same file.
+
+2 - Unset dirty on all the bricks at the end if fop has succeeded on
+all the bricks even if some of the bricks are going through heal.

+Subject: [PATCH 45/52] glusterd: fix txn-id mem leak
+
+This commit ensures the following:
+1. Don't send commit op request to the remote nodes when gluster v
+status all is executed as for the status all transaction the local
+commit gets the name of the volumes and remote commit ops are
+technically a no-op. So no need for additional rpc requests.
+2. In op state machine flow, if the transaction is in staged state and
+op_info.skip_locking is true, then no need to set the txn id in the
+priv->glusterd_txn_opinfo dictionary which never gets freed.

+Subject: [PATCH 46/52] protocol/client: Do not fallback to anon-fd if fd is
+ not open
+
+If an open comes on a file when a brick is down and after the brick comes up,
+a fop comes on the fd, client xlator would still wind the fop on anon-fd
+leading to wrong behavior of the fops in some cases.
+
+Example:
+If lk fop is issued on the fd just after the brick is up in the scenario above,
+lk fop will be sent on anon-fd instead of failing it on that client xlator.
+This lock will never be freed upon close of the fd as flush on anon-fd is
+invalid and is not wound below server xlator.
+
+As a fix, failing the fop unless the fd has FALLBACK_TO_ANON_FD flag.

+Subject: [PATCH 47/52] client-rpc: Fix the payload being sent on the wire
+
+The fops allocate 3 kind of payload(buffer) in the client xlator:
+- fop payload, this is the buffer allocated by the write and put fop
+- rsphdr paylod, this is the buffer required by the reply cbk of
+  some fops like lookup, readdir.
+- rsp_paylod, this is the buffer required by the reply cbk of fops like
+  readv etc.
+
+Currently, in the lookup and readdir fop the rsphdr is sent as payload,
+hence the allocated rsphdr buffer is also sent on the wire, increasing
+the bandwidth consumption on the wire.
+
+With this patch, the issue is fixed.

+Subject: [PATCH 48/52] gfapi: Unblock epoll thread for upcall processing
+
+With commit#ad35193,we have made changes to offload
+processing upcall notifications to synctask so as not
+to block epoll threads. However seems like the issue wasnt
+fully addressed.
+
+In "glfs_cbk_upcall_data" -> "synctask_new1" after creating synctask
+if there is no callback defined, the thread waits on synctask_join
+till the syncfn is finished. So that way even with those changes,
+epoll threads are blocked till the upcalls are processed.
+
+Hence the right fix now is to define a callback function for that
+synctask "glfs_cbk_upcall_syncop" so as to unblock epoll/notify threads
+completely and the upcall processing can happen in parallel by synctask
+threads.

+Subject: [PATCH 50/52] geo-rep: Fix syncing multiple rename of symlink
+
+Problem:
+Geo-rep fails to sync rename of symlink if it's
+renamed multiple times if creation and rename
+happened successively
+
+Worker crash at slave:
+Traceback (most recent call last):
+  File "/usr/libexec/glusterfs/python/syncdaemon/repce.py",  in worker
+    res = getattr(self.obj, rmeth)(*in_data[2:])
+  File "/usr/libexec/glusterfs/python/syncdaemon/resource.py", in entry_ops
+    [ESTALE, EINVAL, EBUSY])
+  File "/usr/libexec/glusterfs/python/syncdaemon/syncdutils.py", in errno_wrap
+    return call(*arg)
+  File "/usr/libexec/glusterfs/python/syncdaemon/libcxattr.py", in lsetxattr
+    cls.raise_oserr()
+  File "/usr/libexec/glusterfs/python/syncdaemon/libcxattr.py", in raise_oserr
+    raise OSError(errn, os.strerror(errn))
+OSError: [Errno 12] Cannot allocate memory
+
+Geo-rep Behaviour:
+1. SYMLINK doesn't record target path in changelog.
+   So while syncing SYMLINK, readlink is done on
+   master to get target path.
+
+2. Geo-rep will create destination if source is not
+   present while syncing RENAME. Hence while syncing
+   RENAME of SYMLINK, target path is collected from
+   destination.
+
+Cause:
+If symlink is created and renamed multiple times, creation of
+symlink is ignored, as it's no longer present on master at
+that path. While symlink is renamed multiple times at master,
+when syncing first RENAME of SYMLINK, both source and destination
+is not present, hence target path is not known.  In this case,
+while creating destination directly at slave,  regular file
+attributes were encoded into blob instead of symlink,
+causing failure in gfid-access translator while decoding
+blob.
+
+Solution:
+While syncing of RENAME of SYMLINK, when target is not known
+and when src and destination is not present on the master,
+don't create destination. Ignore the rename. It's ok to ignore.
+If it's unliked, it's fine.  If it's renamed to something else,
+it will be synced then.

++GlusterFS is a distributed file-system capable of scaling to several
++petabytes. It aggregates various storage bricks over Infiniband RDMA
++or TCP/IP interconnect into one large parallel network file
++system. GlusterFS is one of the most sophisticated file systems in
++terms of features and extensibility.  It borrows a powerful concept
++called Translators from GNU Hurd kernel. Much of the code in GlusterFS
++is in user space and easily manageable.
++
++This package provides the configuration and related files for using
++NFS-Ganesha as the NFS server using GlusterFS

++# Each participating node in the cluster is assigned a virtual IP (VIP)
++# which fails over to another node when its associated ganesha.nfsd dies
++# for any reason. After the VIP is moved to another node all the
++# ganesha.nfsds are send a signal using DBUS to put them into NFS GRACE.
++#
++# There are six resource agent types used: ganesha_mon, ganesha_grace,
++# ganesha_nfsd, IPaddr, and Dummy. ganesha_mon is used to monitor the
++# ganesha.nfsd. ganesha_grace is used to send the DBUS signal to put
++# the remaining ganesha.nfsds into grace. ganesha_nfsd is used to start
++# and stop the ganesha.nfsd during setup and teardown. IPaddr manages
++# the VIP. A Dummy resource named $hostname-trigger_ip-1 is used to
++# ensure that the NFS GRACE DBUS signal is sent after the VIP moves to
++# the new host.

+Subject: [PATCH 056/124] common-ha: fixes for Debian-based systems
+
+1) Debian-based systems don't have /usr/libexec/... and there is
+a hard-coded invocation of /usr/libexec/ganesha/ganesha-ha.sh within
+ganesha-ha.sh itself.
+Fix: save $0 and use it instead for further invocations of self.
+
+2) default shell is /bin/dash (not /bin/bash). Various runner_run()
+invocations for ganesha used what amounts to
+  exec("sh /usr/$libexec/ganesha/ganesha-ha.sh ...);
+which executes the script using the default shell, but there are
+some bash-specific idioms that don't work if the shell is dash.
+Fix: change to exec("/usr/$libexec/ganesha/ganesha-ha.sh ...); so that
+the shebang forces the use of /bin/bash
+
+3) Fedora and RHEL7 have merged /bin/ and /usr/bin, /bin is a symlink
+to /usr/bin. Debian-based systems are not merged, and systemd systems
+have /bin/systemctl. The logic to find .../bin/systemctl is backwards.
+If the logic looks for /usr/bin/systemctl it will not find it on
+Debian-based systems; if it looks for /bin/systemctl it will find it
+on Fedora and RHEL by virtue of the symlink. (RHEL6 and others will
+find their respective init regardless.)
+Fix: change the logic to look for /bin/systemctl instead.
+
+4) The logic for deciding to run systemctl (or not) is a bit silly.
+Fix: simply invoke the found method via the function pointer in the
+table.

+Subject: [PATCH 059/124] glusterd/ganesha : throw proper error for "gluster
+ nfs-ganesha disable"
+
+For first time or if "gluster nfs-ganesha enable" fails the global option
+"nfs-ganesha" won't be stored in glusterd's dictionary. In both cases the
+"gluster nfs-ganesha disable" throws following error :
+"nfs-ganesha: failed: nfs-ganesha is already (null)d."
+
+Also this patch provides the missing prompt for nfs-ganesha disable in 3.10

+During staging phase of volume option "nfs-ganesha", symlink "ganesha.conf"

+happens during commit phase of that option. So if cluster set up fails, the
+ganesha process will be running on all cluster nodes.

+
+If ganesha is not running on one of nodes in HA cluster, then alli dbus

+Subject: [PATCH 063/124] glusterd/ganesha : update cache invalidation properly
+ during volume stop
+
+As per current code, during volume stop for ganesha enabled volume the
+feature.cache-invalidation was turned "off" in ganesha_manage_export().
+And it never turn back to "on" when volume is started. It is not desire
+to modify the volume options during stop, this patch fixes above mentioned
+issue.

+
+Currently unexport is performed by reading export id from volume configuration

+help of dbus command ShowExport. And it will only unexport the share which is
+added via cli.

+Subject: [PATCH 068/124] common-ha: surviving ganesha.nfsd not put in grace on
+ fail-over
+
+Behavior change is seen in new HA in RHEL 7.4 Beta. Up to now clone
+RAs have been created with "pcs resource create ... meta notify=true".
+Their notify method is invoked with pre-start or post-stop when one of
+the clone RAs is started or stopped.
+
+In 7.4 Beta the notify method we observe that the notify method is not
+invoked when one of the clones is stopped (or started).
+
+Ken Gaillot, one of the pacemaker devs, wrote:
+  With the above command, pcs puts the notify=true meta-attribute
+  on the primitive instead of the clone. Looking at the pcs help,
+  that seems expected (--clone notify=true would put it on the clone,
+  meta notify=true puts it on the primitive). If you drop the "meta"
+  above, I think it will work again.
+
+And indeed his suggested fix does work on both RHEL 7.4 Beta and RHEL
+7.3 and presumably Fedora.

+Subject: [PATCH 069/124] common-ha: enable and disable selinux
+ ganesha_use_fusefs
+
+Starting in Fedora 26 and RHEL 7.4 there are new targeted policies
+in selinux which include a tuneable to allow ganesha.nfsd to access
+the gluster (FUSE) shared_storage volume where ganesha maintains its
+state.
+
+N.B. rpm doesn't have a way to distinguish between RHEL 7.3 or 7.4
+so it can't be enabled for RHEL at this time. /usr/sbin/semanage is
+in policycoreutils-python in RHEL (versus policycoreutils-python-utils
+in Fedora.) Once RHEL 7.4 GAs we may also wish to specify the version
+for RHEL 7 explicitly, i.e.
+  Requires: selinux-policy >= 3.13.1-160.
+But beware, the corresponding version in Fedora 26 seems to be
+selinux-policy-3.13.1.258 or so. (Maybe earlier versions, but that's
+what's currently in the F26 beta.
+
+release-3.10 is the upstream master branch for glusterfs-ganesha. For
+release-3.11 and later storhaug needs a similar change, which is
+tracked by https://github.com/linux-ha-storage/storhaug/issues/11
+
+Maybe at some point we would want to consider migrating the targeted
+policies for glusterfs (and nfs-ganesha) from selinux-policy to a
+glusterfs-selinux (and nfs-ganesha-selinux) subpackage?

+Subject: [PATCH 070/124] packaging: glusterfs-ganesha update sometimes fails
+ semanage
+
+Depending on how dnf orders updates, the updated version of
+selinux-policy-targeted with ganesha_use_fusefs may not be updated
+before the glusterfs-ganesha update execute its %post scriptlet
+containing the `semanage ganesha_use_fusefs ...` command. In such
+situations the semanage command (silently) fails.
+
+Use a %trigger (and %triggerun) to run the scriptlet (again) after
+selinux-policy-targeted with ganesha_use_fusefs has been installed
+or updated.
+
+Note: the %triggerun is probably unnecessary, but it doesn't hurt.
+
+The release-3.10 branch is the "upstream master" for the glusterfs-
+ganesha subpackage.
+
+Note: to be merged after https://review.gluster.org/17806

+Subject: [PATCH 081/124] ganesha-ha: ensure pacemaker is enabled after setup
+
+There appears to be a race between `pcs cluster setup ...` early
+in the setup and the `systemctl enable pacemaker` at the end. The
+`pcs cluster setup ...` disables pacemaker and corosync. (Now, in
+pacemaker-1.1.18. Was it always the case?)
+
+I am not able to reproduce this on my devel system. I speculate that
+on a busy system that the `pcs cluster setup ...` disable may, under
+the right conditions, not run until after the setup script enables
+it. It must require the right alignment of the Sun, Moon, and all
+the planets.
+
+Regardless, we'll use the --enable option to `pcs cluster setup ...`
+to ensure that the cluster (re)starts pacemaker.

+Subject: [PATCH 082/124] build: Add dependency on netstat for
+ glusterfs-ganesha pkg
+
+portblock resource-agent needs netstat command but this dependency
+should have been ideally added to resource-agents package. But the
+fixes (bug1395594, bug1395596) are going to be available only
+in the future RHEL 6.9 and RHEL 7.4 releases. Hence as an interim
+workaround, we agreed to add this dependency for glusterfs-ganesha package.

++/************************** Look up heal **************************************/
++/*
++Problem: The CTR xlator records file meta (heat/hardlinks)
++into the data. This works fine for files which are created
++after ctr xlator is switched ON. But for files which were
++created before CTR xlator is ON, CTR xlator is not able to
++record either of the meta i.e heat or hardlinks. Thus making
++those files immune to promotions/demotions.
++
++Solution: The solution that is implemented in this patch is
++do ctr-db heal of all those pre-existent files, using named lookup.
++For this purpose we use the inode-xlator context variable option
++in gluster.
++The inode-xlator context variable for ctr xlator will have the
++following,
++    a. A Lock for the context variable
++    b. A hardlink list: This list represents the successful looked
++       up hardlinks.
++These are the scenarios when the hardlink list is updated:
++1) Named-Lookup: Whenever a named lookup happens on a file, in the
++   wind path we copy all required hardlink and inode information to
++   ctr_db_record structure, which resides in the frame->local variable.
++   We don't update the database in wind. During the unwind, we read the
++   information from the ctr_db_record and ,
++   Check if the inode context variable is created, if not we create it.
++   Check if the hard link is there in the hardlink list.
++      If its not there we add it to the list and send a update to the
++      database using libgfdb.
++      Please note: The database transaction can fail(and we ignore) as there
++      already might be a record in the db. This update to the db is to heal
++      if its not there.
++      If its there in the list we ignore it.
++2) Inode Forget: Whenever an inode forget hits we clear the hardlink list in
++   the inode context variable and delete the inode context variable.
++   Please note: An inode forget may happen for two reason,
++   a. when the inode is delete.
++   b. the in-memory inode is evicted from the inode table due to cache limits.
++3) create: whenever a create happens we create the inode context variable and
++   add the hardlink. The database updation is done as usual by ctr.
++4) link: whenever a hardlink is created for the inode, we create the inode
++ context variable, if not present, and add the hardlink to the list.
++5) unlink: whenever a unlink happens we delete the hardlink from the list.
++6) mknod: same as create.
++7) rename: whenever a rename happens we update the hardlink in list. if the
++   hardlink was not present for updation, we add the hardlink to the list.
++
++What is pending:
++1) This solution will only work for named lookups.
++2) We don't track afr-self-heal/dht-rebalancer traffic for healing.

+Subject: [PATCH 088/124] tier: fix failures noticed during tier start and tier
+ restart.
+
+Problem 1: when tier is started using the tier start command,
+the out put was skipped during a failure. failures don't have an
+transaction id. this id was checked and if its missing then
+it skips.
+
+fix: had to remove the unnecessary jump for that case.
+
+problem 2: When tier was restarted, the tierd doesn't come online.
+This was because, there were a certain values that were supposed
+to be stored in glusterd (gluster-store.c) which will be used
+during restart to come to the original state.
+These values were stored. as they were missing, tierd didn't come
+online.
+
+fix: store the value and make it available during the start.

+Subject: [PATCH 091/124] glusterd/gNFS : explicitly set "nfs.disable" to "off"
+ after 3.2 upgrade
+
+Gluster NFS was enabled by default for all volumes till 3.1. But 3.2 onwards
+for the new volumes it will be disabled by setting "nfs.disable" to "on".
+This take patch will take care of existing volume in such a way that if the
+option is not configured, it will set "nfs.disable" to "off" during op-version
+bump up.
+
+Also this patch removes the warning message while enabling gluster NFS for
+a volume.

+Subject: [PATCH 093/124] glusterd: Change op-version of cache-invalidation in
+ quick-read
+
+In upstream cache-invalidation option in quick read was introduced with
+4.0. There are two problems with it:
+
+1. The key being made duplicate to md-cache xlator, so setting the same
+option actually enables this feature on both md-cache and quick-read.
+2. As the op-version tagged to this key was GD_OP_VERSION_4_0_0, with a RHGS
+3.5 cluster when a md-cache profile is set to a particular volume old
+client fails to mount which is wrong.
+
+Solving 1 with out breaking backward compatibility in upstream is quite hard.
+This patch addresses both the problems in downstream by (a) changing the
+op-version to GD_OP_VERSION_6_0_0 and (b) renaming this key to
+quick-read-cache-invalidation. The fix is currently made downstream only till a
+proper solution is identified in upstream.

+result into backward compatibility issue where an old client can't mount
+a volume configured on a server which is having ctime feature.

+
+	Backport of https://review.gluster.org/c/glusterfs/+/22515
+
+When eager-lock lock acquisition fails because of say network failures, the
+local is not being removed from owners_list, this leads to accumulation of
+waiting frames and the application will hang because the waiting frames are
+under the assumption that another transaction is in the process of acquiring
+lock because owner-list is not empty. Handled this case as well in this patch.
+Added asserts to make it easier to find these problems in future.

+Subject: [PATCH 096/124] core: Brick is not able to detach successfully in
+ brick_mux environment
+
+Problem: In brick_mux environment, while volumes are stopped in a
+         loop bricks are not detached successfully. Brick's are not
+         detached because xprtrefcnt has not become 0 for detached brick.
+         At the time of initiating brick detach process server_notify
+         saves xprtrefcnt on detach brick and once counter has become
+         0 then server_rpc_notify spawn a server_graph_janitor_threads
+         for cleanup brick resources.xprtrefcnt has not become 0 because
+         socket framework is not working due to assigning 0 as a fd for socket.
+         In commit dc25d2c1eeace91669052e3cecc083896e7329b2
+         there was a change in changelog fini to close htime_fd if htime_fd is not
+         negative, by default htime_fd is 0 so it close 0 also.
+
+Solution: Initialize htime_fd to -1 after just allocate changelog_priv
+          by GF_CALLOC

+Subject: [PATCH 097/124] glusterd/tier: while doing an attach tier, the self
+ heal daemon is not getting started
+
+Problem: on a replicated volume, if attach tier is done,
+The shd will be restarted. But here the restart fails because of the
+graph not getting generated properly. The dict which is used for graph
+creation doesn't get the values copied properly in prepare_shd_volume_options()
+glusterd_prepare_shd_volume_options_for_tier() fails and skips the copy.
+
+This patch reverts the changes back to the way it was in 3.4 and
+help in fixing the issue. Using the old dict_set_str works.

+Subject: [PATCH 098/124] mgmt/shd: Implement multiplexing in self heal daemon
+
+Problem:
+
+Shd daemon is per node, which means they create a graph
+with all volumes on it. While this is a great for utilizing
+resources, it is so good in terms of performance and managebility.
+
+Because self-heal daemons doesn't have capability to automatically
+reconfigure their graphs. So each time when any configurations
+changes happens to the volumes(replicate/disperse), we need to restart
+shd to bring the changes into the graph.
+
+Because of this all on going heal for all other volumes has to be
+stopped in the middle, and need to restart all over again.
+
+Solution:
+
+This changes makes shd as a per volume daemon, so that the graph
+will be generated for each volumes.
+
+When we want to start/reconfigure shd for a volume, we first search
+for an existing shd running on the node, if there is none, we will
+start a new process. If already a daemon is running for shd, then
+we will simply detach a graph for a volume and reatach the updated
+graph for the volume. This won't touch any of the on going operations
+for any other volumes on the shd daemon.
+
+Example of an shd graph when it is per volume
+

+Subject: [PATCH 099/124] client/fini: return fini after rpc cleanup
+
+There is a race condition in rpc_transport later
+and client fini.
+
+Sequence of events to happen the race condition
+1) When we want to destroy a graph, we send a parent down
+   event first
+2) Once parent down received on a client xlator, we will
+   initiates a rpc disconnect
+3) This will in turn generates a child down event.
+4) When we process child down, we first do fini for
+   Every xlator
+5) On successful return of fini, we delete the graph
+
+Here after the step 5, there is a chance that the fini
+on client might not be finished. Because an rpc_tranpsort
+ref can race with the above sequence.
+
+So we have to wait till all rpc's are successfully freed
+before returning the fini from client

+Subject: [PATCH 102/124] rpc/transport: Missing a ref on dict while creating
+ transport object
+
+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.

+ client process
+
+Problem: commit c34e4161f3cb6539ec83a9020f3d27eb4759a975 set log-level
+         per xlator during reconfigure only for a brick process not for
+         the client process.
+
+Solution: 1) Change per xlator log-level only if brick_mux is enabled.To make sure
+             about brick multiplex introudce a flag brick_mux at ctx->cmd_args.
+
+Note: There are two other changes done with this patch
+      1) Ignore client-log-level option to attach a brick with
+         already running brick if brick_mux is enabled
+      2) Add a log to print pid of the running process to make easier
+         debugging

+Subject: [PATCH 107/124] gfapi: add function to set client-pid
+
+This api offers the ability to set the pid of a client to a particular
+value, identical to how gluster fuse clients provide the --client-pid
+option. This is an internal API to be used by gluster processes only. See
+https://lists.gluster.org/pipermail/gluster-devel/2019-March/055925.html
+for more details. Currently glfsheal is the only proposed consumer.

+Subject: [PATCH 109/124] glusterd: Optimize glusterd handshaking code path
+
+Problem: At the time of handshaking glusterd populate volume
+         data in a dictionary.While no. of volumes are configured
+         more than 1500 glusterd takes more than 10 min to generated
+         the data.Due to taking more time rpc request times out and
+         rpc start bailing of call frames.
+
+Solution: To optimize the code done below changes
+          1) Spawn multiple threads to populate volumes data in bulk
+             in separate dictionary and introduce an option
+             glusterd.brick-dict-thread-count to configure no. of threads
+             to populate volume data.
+          2) Populate tier data only while volume type is tier

+Problem :  While Geo-rep setup when creating an ssh authorized_keys
+           the geo-rep setup inserts an extra space before the "ssh-rsa" label.
+           This gets flagged by an enterprise customer's security scan as a

+
+Solution: Remove extra space in GSYNCD_CMD & TAR_CMD.

+Subject: [PATCH 114/124] core: fix hang issue in __gf_free
+
+Currently GF_ASSERT is done under mem_accounting lock at some places.
+On a GF_ASSERT failure, gf_msg_callingfn is called which calls gf_malloc
+internally and it takes the same mem_accounting lock leading to deadlock.
+
+This is a temporary fix to avoid any hang issue in master.
+https://review.gluster.org/#/c/glusterfs/+/22589/ is being worked on
+in the mean while so that GF_ASSERT can be used under mem_accounting
+lock.

+Subject: [PATCH 115/124] core: only log seek errors if SEEK_HOLE/SEEK_DATA is
+ available
+
+On RHEL-6 there is no support for SEEK_HOLE/SEEK_DATA and this causes
+the POSIX xlator to return errno=EINVAL. Because of this, the rpc-server
+xlator will log all 'failed' seek attempts. When applications call
+seek() often, the brick logs can grow very quickly and fill up the
+disks.
+
+Messages that get logged are like
+[server-rpc-fops.c:2091:server_seek_cbk] 0-vol01-server: 4947: SEEK-2 (53920aee-062c-4598-aa50-2b4d7821b204), client: worker.example.com-7808-2019/02/08-18:04:57:903430-vol01-client-0-0-0, error-xlator: vol01-posix [Invalid argument]
+
+The problem can be reproduced by running a Gluster Server on RHEL-6,
+with a client running on RHEL-7. The client should execute an
+application that calls lseek() with SEEK_HOLE/SEEK_DATA.

+Subject: [PATCH 116/124] cluster/ec: fix fd reopen
+
+Currently EC tries to reopen fd's that have been opened while a brick
+was down. This is done as part of regular write operations, just after
+having acquired the locks, and it's sent as a sub-fop of the main write
+fop.
+
+There were two problems:
+
+1. The reopen was attempted on all UP bricks, even if a previous lock
+didn't succeed. This is incorrect because most probably the open will
+fail.
+
+2. If reopen is sent and fails, the error is propagated to the main
+operation, causing it to fail when it shouldn't.
+
+To fix this, we only attempt reopens on bricks where the current fop
+owns a lock, and we prevent any error to be propagated to the main
+fop.
+
+To implement this behaviour an argument used to indicate the minimum
+number of required answers has overloaded to also include some flags. To
+make the change consistent, it has been necessary to rename the
+argument, which means that a lot of files have been changed. However
+there are no functional changes.
+
+This change has also uncovered a problem in discard code, which didn't
+correctely process requests of small sizes because no real discard fop
+was being processed, only a write of 0's on some region. In this case
+some fields of the fop remained uninitialized or with incorrect values.
+To fix this, a new function has been created to simulate success on a
+fop and it's used in the discard case.
+
+Thanks to Pranith for providing a test script that has also detected an
+issue in this patch. This patch includes a small modification of this
+script to force data to be written into bricks before stopping them.

+Subject: [PATCH 117/124] spec: Remove thin-arbiter package
+
+Thin-arbiter is not supported in downstream. Updated the
+code to avoid RPMdiff warnings. Marked thin-arbiter
+test cases as bad to avoid nightly runs from reporting
+expected failures.

+Subject: [PATCH 119/124] glusterd: provide a way to detach failed node
+
+When a gluster node in trusted storage pool has failed
+due to hardware issues, volume delete operation fails
+saying "Not all peers are up" and peer detach for failed
+node fails saying "Brick(s) with peer <peer_ip> exists
+in cluster".
+
+The idea here is to use either replace-brick or remove-brick
+command to remove all the bricks hosted by failed node and
+then re-attempting the peer detach. This change adds this
+trick in peer detach error message.

+ during readdirp
+
+Problem:
+   Creation of tar file on gluster volume throws warning
+'file changed as we read it'
+
+Cause:
+   During readdirp, for few of the files whose inode is not
+present, time attributes were served from backend. This caused
+the ctime of few files to be different between before readdir
+and after readdir by tar.
+
+Solution:
+  If ctime feature is enabled and inode is not present, don't
+serve the time attributes from backend file, serve it from xattr.

+Subject: [PATCH 125/141] glusterd: define dumpops in the xlator_api of
+ glusterd
+
+Problem: statedump is not capturing information related to glusterd
+
+Solution: statdump is not capturing glusterd info because
+trav->dumpops is null in gf_proc_dump_single_xlator_info ()
+where trav is glusterd xlator object. trav->dumpops is null
+because we missed to define dumpops in xlator_api of glusterd.
+defining dumpops in xlator_api of glusterd fixes the issue.

+Subject: [PATCH 128/141] glusterd: Fix bulkvoldict thread logic in brick
+ multiplexing
+
+Problem: Currently glusterd spawn bulkvoldict in brick_mux
+         environment while no. of volumes are less than configured
+         glusterd.vol_count_per_thread
+
+Solution: Correct the logic to spawn bulkvoldict thread
+          1) Calculate endindex only while total thread is non zero
+          2) Update end index correctly to pass index for bulkvoldict

+Subject: [PATCH 129/141] core: handle memory accounting correctly
+
+When a translator stops, memory accounting for that translator is not
+destroyed (because there could remain memory allocated that references
+it), but mutexes that coordinate updates of memory accounting were
+destroyed. This caused incorrect memory accounting and even crashes in
+debug mode.
+
+This patch also fixes some other things:
+
+* Reduce the number of atomic operations needed to manage memory
+  accounting.
+* Correctly account memory when realloc() is used.
+* Merge two critical sections into one.
+* Cleaned the code a bit.

+Subject: [PATCH 130/141] tier/test: new-tier-cmds.t fails after a glusterd
+ restart
+
+Problem: new-tier-cmds.t does a restart of gluster processes and
+after the restart the bricks and the tier process takes more
+time than before to come online. This causes the detach start to
+fail.
+
+Fix: Give it enough time to come online after the restart.

+
+...during volume create if the cluster op-version is >=GD_OP_VERSION_7_0.
+
+This option itself was introduced in GD_OP_VERSION_4_0_0 via commit 6daa65356.
+We missed enabling it by default for new volume creates in that commit.
+If we are to do it now safely, we need to use op version
+GD_OP_VERSION_7_0 and target it for release-7.

+Subject: [PATCH 134/141] performance/write-behind: remove request from wip
+ list in wb_writev_cbk
+
+There is a race in the way O_DIRECT writes are handled. Assume two
+overlapping write requests w1 and w2.
+
+* w1 is issued and is in wb_inode->wip queue as the response is still
+  pending from bricks. Also wb_request_unref in wb_do_winds is not yet
+  invoked.
+
+       list_for_each_entry_safe (req, tmp, tasks, winds) {
+		list_del_init (&req->winds);
+
+                if (req->op_ret == -1) {
+			call_unwind_error_keep_stub (req->stub, req->op_ret,
+		                                     req->op_errno);
+                } else {
+                        call_resume_keep_stub (req->stub);
+		}
+
+                wb_request_unref (req);
+        }
+
+* w2 is issued and wb_process_queue is invoked. w2 is not picked up
+  for winding as w1 is still in wb_inode->wip. w1 is added to todo
+  list and wb_writev for w2 returns.
+
+* response to w1 is received and invokes wb_request_unref. Assume
+  wb_request_unref in wb_do_winds (see point 1) is not invoked
+  yet. Since there is one more refcount, wb_request_unref in
+  wb_writev_cbk of w1 doesn't remove w1 from wip.
+
+* wb_process_queue is invoked as part of wb_writev_cbk of w1. But, it
+  fails to wind w2 as w1 is still in wip.
+
+* wb_requet_unref is invoked on w1 as part of wb_do_winds. w1 is
+  removed from all queues including w1.
+
+* After this point there is no invocation of wb_process_queue unless
+  new request is issued from application causing w2 to be hung till
+  the next request.
+
+This bug is similar to bz 1626780 and bz 1379655.

+Subject: [PATCH 135/141] geo-rep: fix incorrectly formatted authorized_keys
+
+There are two ways for creating secret pem pub file during geo-rep
+setup.
+1. gluster-georep-sshkey generate
+2. gluster system:: execute gsec_create
+
+Below patch solves this problem for `gluster-georep-sshkey generate`
+method.
+Patch link: https://review.gluster.org/#/c/glusterfs/+/22246/
+
+This patch is added to support old way of creating secret pem pub file
+`gluster system:: execute gsec_create`.
+
+Problem:  While Geo-rep setup when creating an ssh authorized_keys
+          the geo-rep setup inserts an extra space before the "ssh-rsa" label.
+          This gets flagged by an enterprise customer's security scan as a
+          security violation.
+Solution: Remove extra space while creating secret key.

+Subject: [PATCH 138/141] glusterd: Add gluster volume stop operation to
+ glusterd_validate_quorum()
+
+ISSUE: gluster volume stop succeeds even if quorum is not met.
+
+Fix: Add GD_OP_STOP_VOLUME to gluster_validate_quorum in
+glusterd_mgmt_v3_pre_validate ().
+
+Since the volume stop command has been ported from synctask to mgmt_v3,
+the quorum check was missed out.

+Subject: [PATCH 141/141] socket/ssl: fix crl handling
+
+Problem:
+Just setting the path to the CRL directory in socket_init() wasn't working.
+
+Solution:
+Need to use special API to retrieve and set X509_VERIFY_PARAM and set
+the CRL checking flags explicitly.
+Also, setting the CRL checking flags is a big pain, since the connection
+is declared as failed if any CRL isn't found in the designated file or
+directory. A comment has been added to the code appropriately.

+Subject: [PATCH 144/169] cluster/ec: honor contention notifications for
+ partially acquired locks
+
+EC was ignoring lock contention notifications received while a lock was
+being acquired. When a lock is partially acquired (some bricks have
+granted the lock but some others not yet) we can receive notifications
+from acquired bricks, which should be honored, since we may not receive
+more notifications after that.
+
+Since EC was ignoring them, once the lock was acquired, it was not
+released until the eager-lock timeout, causing unnecessary delays on
+other clients.
+
+This fix takes into consideration the notifications received before
+having completed the full lock acquisition. After that, the lock will
+be releaed as soon as possible.

+Subject: [PATCH 146/169] dht: Custom xattrs are not healed in case of
+ add-brick
+
+Problem: If any custom xattrs are set on the directory before
+         add a brick, xattrs are not healed on the directory
+         after adding a brick.
+
+Solution: xattr are not healed because dht_selfheal_dir_mkdir_lookup_cbk
+          checks the value of MDS and if MDS value is not negative
+          selfheal code path does not take reference of MDS xattrs.Change the
+          condition to take reference of MDS xattr so that custom xattrs are
+          populated on newly added brick

+Subject: [PATCH 148/169] cluster/dht: Lookup all files when processing
+ directory
+
+A rebalance process currently only looks up files
+that it is supposed to migrate. This could cause issues
+when lookup-optimize is enabled as the dir layout can be
+updated with the commit hash before all files are looked up.
+This is expecially problematic if one of the rebalance processes
+fails to complete as clients will try to access files whose
+linkto files might not have been created.
+Each process will now lookup every file in the directory it is
+processing.
+Pros: Less likely that files will be inaccessible.
+Cons: More lookup requests sent to the bricks and a potential
+performance hit.
+Note: this does not handle races such as when a layout is updated on disk
+just as the create fop is sent by the client.

+Subject: [PATCH 149/169] glusterd: Optimize code to copy dictionary in
+ handshake code path
+
+Problem: While high no. of volumes are configured around 2000
+         glusterd has bottleneck during handshake at the time
+         of copying dictionary
+
+Solution: To avoid the bottleneck serialize a dictionary instead
+          of copying key-value pair one by one

+
+1) The placement of cloudsync xlator has been changed

+1) Store ID info will now be stored in the inode ctx
+2) Added new readv type where read is made directly
+   from the remote store. This choice is made by
+   volume set operation.
+3) cs_forget() was missing. Added it.

+Subject: [PATCH 155/169] cloudsync: Make readdirp return stat info of all the
+ dirents
+
+This change got missed while the initial changes were sent.
+Should have been a part of :
+	https://review.gluster.org/#/c/glusterfs/+/21757/
+
+Gist of the change:
+	Function that fills in stat info for dirents is
+invoked in readdirp in posix when cloudsync populates xdata
+request with GF_CS_OBJECT_STATUS.

+Subject: [PATCH 156/169] cloudsync: Fix bug in cloudsync-fops-c.py
+
+In some of the fops generated by generator.py, xdata request
+was not being wound to the child xlator correctly.
+
+This was happening because when though the logic in
+cloudsync-fops-c.py was correct, generator.py was generating
+a resultant code that omits this logic.
+
+Made changes in cloudsync-fops-c.py so that correct code is
+produced.

+Subject: [PATCH 159/169] glusterd: add an op-version check
+
+Problem: "gluster v status" is hung in heterogenous cluster
+when issued from a non-upgraded node.
+
+Cause: commit 34e010d64 fixes the txn-opinfo mem leak
+in op-sm framework by not setting the txn-opinfo if some
+conditions are true. When vol status is issued from a
+non-upgraded node, command is hanging in its upgraded peer
+as the upgraded node setting the txn-opinfo based on new
+conditions where as non-upgraded nodes are following diff
+conditions.
+
+Fix: Add an op-version check, so that all the nodes follow
+same set of conditions to set txn-opinfo.

+Subject: [PATCH 161/169] geo-rep: Fix rename with existing destination with
+ same gfid
+
+Problem:
+   Geo-rep fails to sync the rename properly if destination exists.
+It results in source to be remained on slave causing more number of
+files on slave. Also heavy rename workload like logrotate caused
+lot of ESTALE errors
+
+Cause:
+   Geo-rep fails to sync rename if destination exists if creation
+of source file also falls into single batch of changelogs being
+processed. This is because, after fixing problematic gfids verifying
+from master, while re-processing original entries, CREATE also was
+re-processed causing more files on slave and rename to be failed.
+
+Solution:
+   Entries need to be removed from retrial list after fixing
+problematic gfids on slave so that it's not re-created again on slave.
+   Also treat ESTALE as EEXIST so that the error is properly handled
+verifying the op on master volume.

+Subject: [PATCH 162/169] geo-rep: Fix sync-method config
+
+Problem:
+When 'use_tarssh' is set to true, it exits with successful
+message but the default 'rsync' was used as sync-engine.
+The new config 'sync-method' is not allowed to set from cli.
+
+Analysis and Fix:
+The 'use_tarssh' config is deprecated with new
+config framework and 'sync-method' is the new
+config to choose sync-method i.e. tarssh or rsync.
+This patch fixes the 'sync-method' config. The allowed
+values are tarssh and rsync.

+Subject: [PATCH 163/169] geo-rep: Fix sync hang with tarssh
+
+Problem:
+Geo-rep sync hangs when tarssh is used as sync
+engine at heavy workload.
+
+Analysis and Root cause:
+It's found out that the tar process was hung.
+When debugged further, it's found out that stderr
+buffer of tar process on master was full i.e., 64k.
+When the buffer was copied to a file from /proc/pid/fd/2,
+the hang is resolved.
+
+This can happen when files picked by tar process
+to sync doesn't exist on master anymore. If this count
+increases around 1k, the stderr buffer is filled up.
+
+Fix:
+The tar process is executed using Popen with stderr as PIPE.
+The final execution is something like below.
+
+tar | ssh <args> root@slave tar --overwrite -xf - -C <path>
+
+It was waiting on ssh process first using communicate() and then tar.
+Note that communicate() reads stdout and stderr. So when stderr of tar
+process is filled up, there is no one to read until untar via ssh is
+completed. This can't happen and leads to deadlock.
+Hence we should be waiting on both process parallely, so that stderr is
+read on both processes.

+Subject: [PATCH 164/169] cluster/ec: Fix handling of heal info cases without
+ locks
+
+When we use heal info command, it takes lot of time as in
+some cases it takes lock on entries to find out if the
+entry actually needs heal or not.
+
+There are some cases where we can avoid these locks and
+can conclude if the entry needs heal or not.
+
+1 - We do a lookup (without lock) on an entry, which we found in
+.glusterfs/indices/xattrop, and find that lock count is
+zero. Now if the file contains dirty bit set on all or any
+brick, we can say that this entry needs heal.
+
+2 - If the lock count is one and dirty is greater than 1,
+then it also means that some fop had left the dirty bit set
+which made the dirty count of current fop (which has taken lock)
+more than one. At this point also we can definitely say that
+this entry needs heal.
+
+This patch is modifying code to take into consideration above two
+points.
+It is also changing code to not to call ec_heal_inspect if ec_heal_do
+was called from client side heal. Client side heal triggeres heal
+only when it is sure that it requires heal.
+
+[We have changed the code to not to call heal for lookup]
+

+Subject: [PATCH 165/169] tests/shd: Add test coverage for shd mux
+
+This patch add more test cases for shd mux test cases
+The test case includes
+1) Createing multiple volumes to check the attach and detach
+   of self heal daemon requests.
+2) Make sure the healing happens in all sceanarios
+3) After a volume detach make sure the threads of the detached
+   volume is all cleaned.
+4) Repeat all the above tests for ec volume
+5) Node Reboot case
+6) glusterd restart cases
+7) Add-brick/remove brick
+8) Convert a distributed volume to disperse volume
+9) Convert a replicated volume to distributed volume

+ individual wrapper function
+
+glusterd_svcs_stop should call individual wrapper function to stop a
+daemon rather than calling glusterd_svc_stop. For example for shd,
+it should call glusterd_shdsvc_stop instead of calling basic API
+function to stop. Because the individual functions for each daemon
+could be doing some specific operation in their wrapper function.

+Subject: [PATCH 167/169] glusterd/shd: Optimize the glustershd manager to send
+ reconfigure
+
+Traditionally all svc manager will execute process stop and then
+followed by start each time when they called. But that is not
+required by shd, because the attach request implemented in the shd
+multiplex has the intelligence to check whether a detach is required
+prior to attaching the graph. So there is no need to send an explicit
+detach request if we are sure that the next call is an attach request

+Subject: [PATCH 172/178] ec/fini: Fix race with ec_fini and ec_notify
+
+During a graph cleanup, we first sent a PARENT_DOWN and wait for
+a child down to ultimately free the xlator and the graph.
+
+In the ec xlator, we cleanup the threads when we get a PARENT_DOWN event.
+But a racing event like CHILD_UP or event xl_op may trigger healing threads
+after threads cleanup.
+
+So there is a chance that the threads might access a freed private variabe

+Subject: [PATCH 175/178] ec/fini: Fix race between xlator cleanup and on going
+ async fop
+
+Problem:
+While we process a cleanup, there is a chance for a race between
+async operations, for example ec_launch_replace_heal. So this can
+lead to invalid mem access.
+
+Solution:
+Just like we track on going heal fops, we can also track fops like
+ec_launch_replace_heal, so that we can decide when to send a
+PARENT_DOWN request.

+Subject: [PATCH 176/178] features/shard: Fix crash during background shard
+ deletion in a specific case
+
+Consider the following case -
+1. A file gets FALLOCATE'd such that > "shard-lru-limit" number of
+   shards are created.
+2. And then it is deleted after that.
+
+The unique thing about FALLOCATE is that unlike WRITE, all of the
+participant shards are resolved and created and fallocated in a single
+batch. This means, in this case, after the first "shard-lru-limit"
+number of shards are resolved and added to lru list, as part of
+resolution of the remaining shards, some of the existing shards in lru
+list will need to be evicted. So these evicted shards will be
+inode_unlink()d as part of eviction. Now once the fop gets to the actual
+FALLOCATE stage, the lru'd-out shards get added to fsync list.
+
+2 things to note at this point:
+i. the lru'd out shards are only part of fsync list, so each holds 1 ref
+   on base shard
+ii. and the more recently used shards are part of both fsync and lru list.
+    So each of these shards holds 2 refs on base inode  - one for being
+    part of fsync list, and the other for being part of lru list.
+
+FALLOCATE completes successfully and then this very file is deleted, and
+background shard deletion launched. Here's where the ref counts get mismatched.
+First as part of inode_resolve()s during the deletion, the lru'd-out inodes
+return NULL, because they are inode_unlink()'d by now. So these inodes need to
+be freshly looked up. But as part of linking them in lookup_cbk (precisely in
+shard_link_block_inode()), inode_link() returns the lru'd-out inode object.
+And its inode ctx is still valid and ctx->base_inode valid from the last
+time it was added to list.
+
+But shard_common_lookup_shards_cbk() passes NULL in the place of base_pointer
+to __shard_update_shards_inode_list(). This means, as part of adding the lru'd out
+inode back to lru list, base inode is not ref'd since its NULL.
+
+Whereas post unlinking this shard, during shard_unlink_block_inode(),
+ctx->base_inode is accessible and is unref'd because the shard was found to be part
+of LRU list, although the matching ref didn't occur. This at some point leads to
+base_inode refcount becoming 0 and it getting destroyed and released back while some
+of its associated shards are continuing to be unlinked in parallel and the client crashes
+whenever it is accessed next.
+
+Fix is to pass base shard correctly, if available, in shard_link_block_inode().
+
+Also, the patch fixes the ret value check in tests/bugs/shard/shard-fallocate.c

+Subject: [PATCH 177/178] features/shard: Fix extra unref when inode object is
+ lru'd out and added back
+
+Long tale of double unref! But do read...
+
+In cases where a shard base inode is evicted from lru list while still
+being part of fsync list but added back soon before its unlink, there
+could be an extra inode_unref() leading to premature inode destruction
+leading to crash.
+
+One such specific case is the following -
+
+Consider features.shard-deletion-rate = features.shard-lru-limit = 2.
+This is an oversimplified example but explains the problem clearly.
+
+First, a file is FALLOCATE'd to a size so that number of shards under
+/.shard = 3 > lru-limit.
+Shards 1, 2 and 3 need to be resolved. 1 and 2 are resolved first.
+Resultant lru list:
+                               1 -----> 2
+refs on base inode -          (1)  +   (1) = 2
+3 needs to be resolved. So 1 is lru'd out. Resultant lru list -
+		               2 -----> 3
+refs on base inode -          (1)  +   (1) = 2
+
+Note that 1 is inode_unlink()d but not destroyed because there are
+non-zero refs on it since it is still participating in this ongoing
+FALLOCATE operation.
+
+FALLOCATE is sent on all participant shards. In the cbk, all of them are
+added to fync_list.
+Resulting fsync list -
+                               1 -----> 2 -----> 3 (order doesn't matter)
+refs on base inode -          (1)  +   (1)  +   (1) = 3
+Total refs = 3 + 2 = 5
+
+Now an attempt is made to unlink this file. Background deletion is triggered.
+The first $shard-deletion-rate shards need to be unlinked in the first batch.
+So shards 1 and 2 need to be resolved. inode_resolve fails on 1 but succeeds
+on 2 and so it's moved to tail of list.
+lru list now -
+                              3 -----> 2
+No change in refs.
+
+shard 1 is looked up. In lookup_cbk, it's linked and added back to lru list
+at the cost of evicting shard 3.
+lru list now -
+                              2 -----> 1
+refs on base inode:          (1)  +   (1) = 2
+fsync list now -
+                              1 -----> 2 (again order doesn't matter)
+refs on base inode -         (1)  +   (1) = 2
+Total refs = 2 + 2 = 4
+After eviction, it is found 3 needs fsync. So fsync is wound, yet to be ack'd.
+So it is still inode_link()d.
+
+Now deletion of shards 1 and 2 completes. lru list is empty. Base inode unref'd and
+destroyed.
+In the next batched deletion, 3 needs to be deleted. It is inode_resolve()able.
+It is added back to lru list but base inode passed to __shard_update_shards_inode_list()
+is NULL since the inode is destroyed. But its ctx->inode still contains base inode ptr
+from first addition to lru list for no additional ref on it.
+lru list now -
+                              3
+refs on base inode -         (0)
+Total refs on base inode = 0
+Unlink is sent on 3. It completes. Now since the ctx contains ptr to base_inode and the
+shard is part of lru list, base shard is unref'd leading to a crash.
+
+FIX:
+When shard is readded back to lru list, copy the base inode pointer as is into its inode ctx,
+even if it is NULL. This is needed to prevent double unrefs at the time of deleting it.

+Subject: [PATCH 178/178] Cluster/afr: Don't treat all bricks having metadata
+ pending as split-brain
+
+Backport of: https://review.gluster.org/#/c/glusterfs/+/22831/
+
+Problem:
+We currently don't have a roll-back/undoing of post-ops if quorum is not met.
+Though the FOP is still unwound with failure, the xattrs remain on the disk.
+Due to these partial post-ops and partial heals (healing only when 2 bricks
+are up), we can end up in metadata split-brain purely from the afr xattrs
+point of view i.e each brick is blamed by atleast one of the others for
+metadata. These scenarios are hit when there is frequent connect/disconnect
+of the client/shd to the bricks.
+
+Fix:
+Pick a source based on the xattr values. If 2 bricks blame one, the blamed
+one must be treated as sink. If there is no majority, all are sources. Once
+we pick a source, self-heal will then do the heal instead of erroring out
+due to split-brain.
+This patch also adds restriction of all the bricks to be up to perform
+metadata heal to avoid any metadata loss.
+
+Removed the test case tests/bugs/replicate/bug-1468279-source-not-blaming-sinks.t
+as it was doing metadata heal even when only 2 of 3 bricks were up.

+Subject: [PATCH 179/192] tests: Fix split-brain-favorite-child-policy.t
+ failure
+
+Backport of: https://review.gluster.org/#/c/glusterfs/+/22850/
+
+Problem:
+The test case is failing to heal the volume within $HEAL_TIMEOUT @195.
+This is happening because as part of split-brain resolution the file
+gets expunged from the sink and the new entry mark for that file will
+be done on the source bricks as part of impunging. Since the source
+bricks shd-threads failed to get the heal-domain lock, they will wait
+for the heal-timeout of 10 minutes, which is greater than $HEAL_TIMEOUT.
+
+Fix:
+Set the cluster.heal-timeout to 5 seconds to trigger the heal so that
+one of the source brick heals the file within the $HEAL_TIMEOUT.

+Subject: [PATCH 181/192] afr: log before attempting data self-heal.
+
+Upstream patch: https://review.gluster.org/#/c/glusterfs/+/22685/
+
+I was working on a blog about troubleshooting AFR issues and I wanted to copy
+the messages logged by self-heal for my blog. I then realized that AFR-v2 is not
+logging *before* attempting data heal while it logs it for metadata and entry
+heals.

+Adding it in this patch. Now there is a 'performing' and a corresponding
+'Completed' message for every type of heal.

+
+Problem:
+
+Unable to setup mountbroker root directory while creating geo-replication
+session for non-root user.
+
+Casue:
+With patch[1] which defines the max-port for glusterd one extra sapce
+got added in field of 'option max-port'.
+[1]. https://review.gluster.org/#/c/glusterfs/+/21872/
+
+In geo-rep spliting of key-value pair form vol file was done on the
+basis of space so this additional space caused "ValueError: too many values
+to unpack".
+
+Solution:
+Use split so that it can treat consecutive whitespace as a single separator.

+Subject: [PATCH 183/192] glusterd/svc: Stop stale process using the
+ glusterd_proc_stop
+
+While restarting a glusterd process, when we have a stale pid
+we were doing a simple kill. Instead we can use glusterd_proc_stop
+Because it has more logging plus force kill in case if there is
+any problem with kill signal handling.

+Subject: [PATCH 185/192] gfapi: provide an api for setting statedump path
+
+Currently for an application using glfsapi to use glusterfs, when a
+statedump is taken, it uses /var/run/gluster dir to dump info.
+
+There can be concerns as this directory may be owned by some other
+user, and hence it may fail taking statedump. Such applications
+should have an option to use different path.
+
+This patch provides an API to do so.

+
+An API should have the proper version number, and 'future' version
+number is just a place holder. One shouldn't be using it in the
+release versions.
+
+With the previous backport of the patch, the version remained same
+as that of 'master' branch, which is future, but as it is an API,
+it needed a fixed version number. With this patch, corrected the same.

+Subject: [PATCH 189/192] features/shard: Fix block-count accounting upon
+ truncate to lower size
+
+    > Upstream: https://review.gluster.org/22681
+    > BUG: 1705884
+    > Change-Id: I9128a192e9bf8c3c3a959e96b7400879d03d7c53
+
+The way delta_blocks is computed in shard is incorrect, when a file
+is truncated to a lower size. The accounting only considers change
+in size of the last of the truncated shards.
+
+FIX:
+
+Get the block-count of each shard just before an unlink at posix in
+xdata.  Their summation plus the change in size of last shard
+(from an actual truncate) is used to compute delta_blocks which is
+used in the xattrop for size update.

+Subject: [PATCH 190/192] Build: removing the hardcoded usage of python3
+
+Label : DOWNSTREAM ONLY
+
+Problem: RHEL8 needed python3 so python3 was hardcoded to be used
+in gluster build. python2 was still being used by RHEL7 machines and
+when the shebang was redirected to use python3 glusterfind failed.
+It was not working from 6.0-5 downstream build.
+
+Fix: revert back to the old mechanism where we check the python version
+and redirect the python script according to the usage.

+Subject: [PATCH 192/192] build: Ensure gluster-cli package is built as part of
+ client build
+
+Till RHGS 3.4.x RHGS client was shipping gluster-cli rpm. With RHGS 3.5
+which is a rebase of glusterfs 6.0 gluster-cli is only built for server.
+gluster cli offers a remote cli execution capability with --remote-host
+option for which you need not to have cli and glusterd co located and
+hence shipping cli as part of the client package is mandatory. With out
+this change the client upgrade for RHEL minor versions are also broken.

+Subject: [PATCH 194/221] stack: Make sure to have unique call-stacks in all
+ cases
+
+At the moment new stack doesn't populate frame->root->unique in all cases. This
+makes it difficult to debug hung frames by examining successive state dumps.
+Fuse and server xlators populate it whenever they can, but other xlators won't
+be able to assign 'unique' when they need to create a new frame/stack because
+they don't know what 'unique' fuse/server xlators already used. What we need is
+for unique to be correct. If a stack with same unique is present in successive
+statedumps, that means the same operation is still in progress. This makes
+'finding hung frames' part of debugging hung frames easier.

+Subject: [PATCH 196/221] posix/ctime: Fix ctime upgrade issue
+
+Problem:
+On a EC volume, during upgrade from the older version where
+ctime feature is not enabled(or not present) to the newer
+version where the ctime feature is available (enabled default),
+the self heal hangs and doesn't complete.
+
+Cause:
+The ctime feature has both client side code (utime) and
+server side code (posix). The feature is driven from client.
+Only if the client side sets the time in the frame, should
+the server side sets the time attributes in xattr. But posix
+setattr/fseattr was not doing that. When one of the server
+nodes is updated, since ctime is enabled by default, it
+starts setting xattr on setattr/fseattr on the updated node/brick.
+
+On a EC volume the first two updated nodes(bricks) are not a
+problem because there are 4 other bricks with consistent data.
+However once the third brick is updated, the new attribute(mdata xattr)
+will cause an inconsistency on metadata on 3 bricks, which
+prevents the file to be repaired.
+
+Fix:
+Don't create mdata xattr with utimes/utimensat system call.
+Only update if already present.

+Subject: [PATCH 198/221] cluster/ec: Prevent double pre-op xattrops
+
+Problem:
+Race:
+Thread-1                                    Thread-2
+1) Does ec_get_size_version() to perform
+pre-op fxattrop as part of write-1
+                                           2) Calls ec_set_dirty_flag() in
+                                              ec_get_size_version() for write-2.
+					      This sets dirty[] to 1
+3) Completes executing
+ec_prepare_update_cbk leading to
+ctx->dirty[] = '1'
+					   4) Takes LOCK(inode->lock) to check if there are
+					      any flags and sets dirty-flag because
+				              lock->waiting_flag is 0 now. This leads to
+					      fxattrop to increment on-disk dirty[] to '2'
+
+At the end of the writes the file will be marked for heal even when it doesn't need heal.
+
+Fix:
+Perform ec_set_dirty_flag() and other checks inside LOCK() to prevent dirty[] to be marked
+as '1' in step 2) above

+Subject: [PATCH 199/221] upcall: Avoid sending notifications for invalid
+ inodes
+
+For nameless LOOKUPs, server creates a new inode which shall
+remain invalid until the fop is successfully processed post
+which it is linked to the inode table.
+
+But incase if there is an already linked inode for that entry,
+it discards that newly created inode which results in upcall
+notification. This may result in client being bombarded with
+unnecessary upcalls affecting performance if the data set is huge.
+
+This issue can be avoided by looking up and storing the upcall
+context in the original linked inode (if exists), thus saving up on
+those extra callbacks.
+
+This is backport of below upstream fix -

+Subject: [PATCH 202/221] shd/mux: Fix race between mux_proc unlink and stop
+
+There is a small race window, where we have a shd proc
+without having a connection. That is when we stopped the
+last shd running on a process. The list was removed
+outside of a lock just after stopping the process.
+
+So there is a window where we stopped the process, but
+the shd proc list contains the entry.

+Subject: [PATCH 203/221] glusterd/shd: Change shd logfile to a unique name
+
+With the shd mux changes, shd was havinga a logfile
+with volname of the first started volume.
+
+This was creating a lot confusion, as other volumes data
+is also logging to a logfile which has a different vol name.
+
+With this changes the logfile will be changed to a unique name
+ie "/var/log/glusterfs/glustershd.log". This was the same
+logfile name before the shd mux

+Subject: [PATCH 205/221] glusterd: Can't run rebalance due to long unix socket
+
+Problem: glusterd populate unix socket file name based
+         on volname and if volname is lengthy socket
+         system call's are failed due to breach maximum length
+         is defined in the kernel.
+
+Solution:Convert unix socket name to hash to resolve the issue

+Subject: [PATCH 207/221] glusterd: fix use-after-free of a dict_t
+
+A dict was passed to a function that calls dict_unref() without taking
+any additional reference. Given that the same dict is also used after
+the function returns, this was causing a use-after-free situation.
+
+To fix the issue, we simply take an additional reference before calling
+the function.

+From: Xavi Hernandez <xhernandez@redhat.com>
+Date: Tue, 5 Mar 2019 18:58:20 +0100
+Subject: [PATCH 209/221] core: avoid dynamic TLS allocation when possible
+
+Some interdependencies between logging and memory management functions
+make it impossible to use the logging framework before initializing
+memory subsystem because they both depend on Thread Local Storage
+allocated through pthread_key_create() during initialization.
+
+This causes a crash when we try to log something very early in the
+initialization phase.
+
+To prevent this, several dynamically allocated TLS structures have
+been replaced by static TLS reserved at compile time using '__thread'
+keyword. This also reduces the number of error sources, making
+initialization simpler.

+Subject: [PATCH 212/221] core: fix memory allocation issues
+
+Two problems have been identified that caused that gluster's memory
+usage were twice higher than required.
+
+1. An off by 1 error caused that all objects allocated from the memory
+   pools were taken from a pool bigger than required. Since each pool
+   corresponds to a size equal to a power of two, this was wasting half
+   of the available memory.
+
+2. The header information used for accounting on each memory object was
+   not taken into consideration when searching for a suitable memory
+   pool. It was added later when each individual block was allocated.
+   This made this space "invisible" to memory accounting.
+
+Credits: Thanks to Nithya Balachandran for identifying this problem and
+         testing this patch.

+Subject: [PATCH 214/221] geo-rep: Upgrading config file to new version
+
+- configuration handling is enhanced with patch
+https://review.gluster.org/#/c/glusterfs/+/18257/
+- hence, the old configurations are not applied when
+Geo-rep session is created in the old version and upgraded.
+
+This patch solves the issue. It,
+- checks if the config file is old.
+- parses required values from old config file and stores in new
+  config file, which ensures that configurations are applied on
+  upgrade.
+- stores old config file as backup.
+- handles changes in options introduced in
+  https://review.gluster.org/#/c/glusterfs/+/18257/

+Subject: [PATCH 217/221] uss: Fix tar issue with ctime and uss enabled
+
+Problem:
+If ctime and uss enabled, tar still complains with 'file
+changed as we read it'
+
+Cause:
+To clear nfs cache (gluster-nfs), the ctime was incremented
+in snap-view client on stat cbk.
+
+Fix:
+The ctime should not be incremented manually. Since gluster-nfs
+is planning to be deprecated, this code is being removed to
+fix the issue.

+
+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 does
+fini as well as other common rec free.

+ xlator
+
+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

+Subject: [PATCH 221/221] protocol/client: propagte GF_EVENT_CHILD_PING only
+ for connections to brick
+
+Two reasons:
+* ping responses from glusterd may not be relevant for Halo
+  replication. Instead, it might be interested in only knowing whether
+  the brick itself is responsive.
+* When a brick is killed, propagating GF_EVENT_CHILD_PING of ping
+  response from glusterd results in GF_EVENT_DISCONNECT spuriously
+  propagated to parent xlators. These DISCONNECT events are from the
+  connections client establishes with glusterd as part of its
+  reconnect logic. Without GF_EVENT_CHILD_PING, the last event
+  propagated to parent xlators would be the first DISCONNECT event
+  from brick and hence subsequent DISCONNECTS to glusterd are not
+  propagated as protocol/client prevents same event being propagated
+  to parent xlators consecutively. propagating GF_EVENT_CHILD_PING for
+  ping responses from glusterd would change the last_sent_event to
+  GF_EVENT_CHILD_PING and hence protocol/client cannot prevent
+  subsequent DISCONNECT events

+Subject: [PATCH 223/255] change get_real_filename implementation to use
+ ENOATTR instead of ENOENT
+
+get_real_filename is implemented as a virtual extended attribute to help
+Samba implement the case-insensitive but case preserving SMB protocol
+more efficiently. It is implemented as a getxattr call on the parent directory
+with the virtual key of "get_real_filename:<entryname>" by looking for a
+spelling with different case for the provided file/dir name (<entryname>)
+and returning this correct spelling as a result if the entry is found.
+Originally (05aaec645a6262d431486eb5ac7cd702646cfcfb), the
+implementation used the ENOENT errno to return the authoritative answer
+that <entryname> does not exist in any case folding.
+
+Now this implementation is actually a violation or misuse of the defined
+API for the getxattr call which returns ENOENT for the case that the dir
+that the call is made against does not exist and ENOATTR (or the synonym
+ENODATA) for the case that the xattr does not exist.
+
+This was not a problem until the gluster fuse-bridge was changed
+to do map ENOENT to ESTALE in 59629f1da9dca670d5dcc6425f7f89b3e96b46bf,
+after which we the getxattr call for get_real_filename returned an
+ESTALE instead of ENOENT breaking the expectation in Samba.
+
+It is an independent problem that ESTALE should not leak out to user
+space but is intended to trigger retries between fuse and gluster.
+But nevertheless, the semantics seem to be incorrect here and should
+be changed.
+
+This patch changes the implementation of the get_real_filename virtual
+xattr to correctly return ENOATTR instead of ENOENT if the file/directory
+being looked up is not found.
+
+The Samba glusterfs_fuse vfs module which takes advantage of the
+get_real_filename over a fuse mount will receive a corresponding change
+to map ENOATTR to ENOENT. Without this change, it will still work
+correctly, but the performance optimization for nonexisting files is
+lost. On the other hand side, this change removes the distinction
+between the old not-implemented case and the implemented case.
+So Samba changed to treat ENOATTR like ENOENT will not work correctly
+any more against old servers that don't implement get_real_filename.
+I.e. existing files will be reported as non-existing
+

+Subject: [PATCH 226/255] geo-rep : fix gluster command path for non-root
+ session
+
+Problem:
+gluster command not found.
+
+Cause:
+In Volinfo class we issue command 'gluster vol info' to get information
+about volume like getting brick_root to perform various operation.
+When geo-rep session is configured for non-root user Volinfo class
+fails to issue gluster command due to unavailability of gluster
+binary path for non-root user.
+
+Solution:
+Use config value 'slave-gluster-command-dir'/'gluster-command-dir' to get path
+for gluster command based on caller.

+Subject: [PATCH 227/255] glusterd/svc: update pid of mux volumes from the shd
+ process
+
+For a normal volume, we are updating the pid from a the
+process while we do a daemonization or at the end of the
+init if it is no-daemon mode. Along with updating the pid
+we also lock the file, to make sure that the process is
+running fine.
+
+With brick mux, we were updating the pidfile from gluterd
+after an attach/detach request.
+
+There are two problems with this approach.
+1) We are not holding a pidlock for any file other than parent
+   process.
+2) There is a chance for possible race conditions with attach/detach.
+   For example, shd start and a volume stop could race. Let's say
+   we are starting an shd and it is attached to a volume.
+   While we trying to link the pid file to the running process,
+   this would have deleted by the thread that doing a volume stop.

+Problem: get-state does not show correct brick status if brick
+         status is not Started, it always shows started if any value
+         is set brickinfo->status
+
+Solution: Check the value of brickinfo->status to show correct status

+Subject: [PATCH 232/255] cluster/afr: Fix incorrect reporting of gfid & type
+ mismatch
+
+Backport of: https://review.gluster.org/#/c/glusterfs/+/22908/
+
+Problems:
+1. When checking for type and gfid mismatch, if the type or gfid
+is unknown because of missing gfid handle and the gfid xattr
+it will be reported as type or gfid mismatch and the heal will
+not complete.
+
+2. If the source selected during entry heal has null gfid the same
+will be sent to afr_lookup_and_heal_gfid(). In this function when
+we try to assign the gfid on the bricks where it does not exist,
+we are considering the same gfid and try to assign that on those
+bricks. This will fail in posix_gfid_set() since the gfid sent
+is null.
+
+Fix:
+If the gfid sent to afr_lookup_and_heal_gfid() is null choose a
+valid gfid before proceeding to assign the gfid on the bricks
+where it is missing.
+
+In afr_selfheal_detect_gfid_and_type_mismatch(), do not report
+type/gfid mismatch if the type/gfid is unknown or not set.

+Subject: [PATCH 251/255] tests: Fix
+ bug-1717819-metadata-split-brain-detection.t failure
+
+<Backport of: https://review.gluster.org/#/c/glusterfs/+/23043/>
+
+Problem:
+tests/bugs/replicate/bug-1717819-metadata-split-brain-detection.t fails
+intermittently in test cases #49 & #50, which compare the values of the
+user set xattr values after enabling the heal. We are not waiting for
+the heal to complete before comparing those values, which might lead
+those tests to fail.
+
+Fix:
+Wait till the HEAL-TIMEOUT before comparing the xattr values.
+Also cheking for the shd to come up and the bricks to connect to the shd
+process in another case.

+Subject: [PATCH 252/255] glusterd: do not mark skip_locking as true for
+ geo-rep operations
+
+We need to send the commit req to peers in case of geo-rep
+operations even though it is a no volname operation. In commit
+phase peers try to set the txn_opinfo which will fail because
+it is a no volname operation where we don't require a commit
+phase. We mark skip_locking as true for no volname operations,
+but we have to give an exception to geo-rep operations, so that
+they can set txn_opinfo in commit phase.
+
+Please refer to detailed RCA at the bug: 1729463

+Subject: [PATCH 253/255] core: fix deadlock between statedump and
+ fd_anonymous()
+
+There exists a deadlock between statedump generation and fd_anonymous()
+function because they are acquiring inode table lock and inode lock in
+reverse order.
+
+This patch modifies fd_anonymous() so that it takes inode lock only when
+it's really necessary, avoiding the deadlock.

+Subject: [PATCH 256/261] features/snapview-server: use the same volfile server
+ for gfapi options
+
+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.

+Subject: [PATCH 258/261] geo-rep: Fix mount broker setup issue
+
+The patch [1] added validation in gverify.sh to check if the gluster
+binary on slave by executing gluster directly on slave.  But for
+non-root users, even though gluster binary is present, path is not
+found when executed via ssh. Hence validate the gluster binary using
+bash builtin 'type' command.

+Subject: [PATCH 260/261] ctime: Set mdata xattr on legacy files
+
+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.

+
+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()

+Subject: [PATCH 264/265] gfapi: Fix deadlock while processing upcall
+
+As mentioned in bug1733166, there could be potential deadlock
+while processing upcalls depending on how each xlator choose
+to act on it. The right way of fixing such issues
+is to change rpc callback communication process.
+- https://github.com/gluster/glusterfs/issues/697
+
+Till then, making changes in gfapi layer to avoid any I/O
+processing.
+
+This is backport of below mainline patch

+Subject: [PATCH 267/276] posix/ctime: Fix race during lookup ctime xattr heal
+
+Problem:
+Ctime heals the ctime xattr ("trusted.glusterfs.mdata") in lookup
+if it's not present. In a multi client scenario, there is a race
+which results in updating the ctime xattr to older value.
+
+e.g. Let c1 and c2 be two clients and file1 be the file which
+doesn't have the ctime xattr. Let the ctime of file1 be t1.
+(from backend, ctime heals time attributes from backend when not present).
+
+Now following operations are done on mount
+c1 -> ls -l /mnt/file1  |   c2 -> ls -l /mnt/file1;echo "append" >> /mnt/file1;
+
+The race is that the both c1 and c2 didn't fetch the ctime xattr in lookup,
+so both of them tries to heal ctime to time 't1'. If c2 wins the race and
+appends the file before c1 heals it, it sets the time to 't1' and updates
+it to 't2' (because of append). Now c1 proceeds to heal and sets it to 't1'
+which is incorrect.
+
+Solution:
+Compare the times during heal and only update the larger time. This is the
+general approach used in ctime feature but got missed with healing legacy
+files.

+Subject: [PATCH 268/276] rpc/transport: have default listen-port
+
+With release-6, we now can have transport.socket.listen-port parameter
+configurable in glusterd.vol. However the default value wasn't defined
+in the code and this breaks the backward compatibility where if one has
+a modified glusterd.vol file, then post upgrade the same file will be
+retained and the new changes introduced as part of the release wouldn't
+be available in the glusterd.vol. So it's important that for each new
+options introduced in glusterd.vol file backward compatibility is
+guaranteed.

+Subject: [PATCH 271/276] cluster/ec: fix EIO error for concurrent writes on
+ sparse files
+
+EC doesn't allow concurrent writes on overlapping areas, they are
+serialized. However non-overlapping writes are serviced in parallel.
+When a write is not aligned, EC first needs to read the entire chunk
+from disk, apply the modified fragment and write it again.
+
+The problem appears on sparse files because a write to an offset
+implicitly creates data on offsets below it (so, in some way, they
+are overlapping). For example, if a file is empty and we read 10 bytes
+from offset 10, read() will return 0 bytes. Now, if we write one byte
+at offset 1M and retry the same read, the system call will return 10
+bytes (all containing 0's).
+
+So if we have two writes, the first one at offset 10 and the second one
+at offset 1M, EC will send both in parallel because they do not overlap.
+However, the first one will try to read missing data from the first chunk
+(i.e. offsets 0 to 9) to recombine the entire chunk and do the final write.
+This read will happen in parallel with the write to 1M. What could happen
+is that half of the bricks process the write before the read, and the
+half do the read before the write. Some bricks will return 10 bytes of
+data while the otherw will return 0 bytes (because the file on the brick
+has not been expanded yet).
+
+When EC tries to recombine the answers from the bricks, it can't, because
+it needs more than half consistent answers to recover the data. So this
+read fails with EIO error. This error is propagated to the parent write,
+which is aborted and EIO is returned to the application.
+
+The issue happened because EC assumed that a write to a given offset
+implies that offsets below it exist.
+
+This fix prevents the read of the chunk from bricks if the current size
+of the file is smaller than the read chunk offset. This size is
+correctly tracked, so this fixes the issue.
+
+Also modifying ec-stripe.t file for Test #13 within it.
+In this patch, if a file size is less than the offset we are writing, we
+fill zeros in head and tail and do not consider it strip cache miss.
+That actually make sense as we know what data that part holds and there is
+no need of reading it from bricks.

+Subject: [PATCH 273/276] cluster/ec: Fix reopen flags to avoid misbehavior
+
+Problem:
+when a file needs to be re-opened O_APPEND and O_EXCL
+flags are not filtered in EC.
+
+- O_APPEND should be filtered because EC doesn't send O_APPEND below EC for
+open to make sure writes happen on the individual fragments instead of at the
+end of the file.
+
+- O_EXCL should be filtered because shd could have created the file so even
+when file exists open should succeed
+
+- O_CREAT should be filtered because open happens with gfid as parameter. So
+open fop will create just the gfid which will lead to problems.
+
+Fix:
+Filter out these two flags in reopen.

+Subject: [PATCH 275/276] cluster/ec: Create heal task with heal process id
+
+Problem:
+ec_data_undo_pending calls syncop_fxattrop->SYNCOP without
+a frame. In this case SYNCOP gets the frame of the task.
+However, when we create a synctask for heal we provide
+frame as NULL.
+Now, if the read-only feature is ON, it will receive the
+process ID of the shd as 0 and will consider that it as
+not an internal process. This will prevent healing of a
+file with "Read-only file system" error message log.
+
+Solution:
+While launching heal, create a synctask using frame and set
+process id of the SHD which is -6.

+Subject: [PATCH 280/284] performance/md-cache: Do not skip caching of null
+ character xattr values
+
+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.

+
+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.

+Subject: [PATCH 282/284] geo-rep: Fix the name of changelog archive file
+
+Background:
+The processed changelogs are archived each month in a single tar file.
+The default format is "archive_YYYYMM.tar" which is specified as "%%Y%%m"
+in configuration file.
+
+Problem:
+The created changelog archive file didn't have corresponding year
+and month. It created as "archive_%Y%m.tar" on python2 only systems.
+
+Cause and Fix:
+Geo-rep expects "%Y%m" after the ConfigParser reads it from config file.
+Since it was "%%Y%%m" in config file, geo-rep used to get correct value
+"%Y%m" in python3 and "%%Y%%m" in python2 which is incorrect.
+The fix can be to use "%Y%m" in config file but that fails in python3.
+So the fix is to use "RawConfigParser" in geo-rep and use "%Y%m". This
+works both in python2 and python3.

+ posix_fs_health_check
+
+Problem: Sometime brick is going down to health check thread is
+         failed without logging error codes return by aio system calls.
+         As per aio_error man page it returns a positive error number
+         if the asynchronous I/O operation failed.
+
+Solution: log aio_error return codes in error message

+Subject: [PATCH 287/297] cluster/ec: Fail fsync/flush for files on update
+ size/version failure
+
+Problem:
+If update size/version is not successful on the file, updates on the
+same stripe could lead to data corruptions if the earlier un-aligned
+write is not successful on all the bricks. Application won't have
+any knowledge of this because update size/version happens in the
+background.
+
+Fix:
+Fail fsync/flush on fds that are opened before update-size-version
+went bad.

+Subject: [PATCH 291/297] cluster/ec: Mark release only when it is acquired
+
+Problem:
+Mount-1                                Mount-2
+1)Tries to acquire lock on 'dir1'   1)Tries to acquire lock on 'dir1'
+2)Lock is granted on brick-0        2)Lock gets EAGAIN on brick-0 and
+				      leads to blocking lock on brick-0
+3)Gets a lock-contention            3) Doesn't matter what happens on mount-2
+  notification, marks lock->release    from here on.
+  to true.
+4)New fop comes on 'dir1' which will
+  be put in frozen list as lock->release
+  is set to true.
+5) Lock acquisition from step-2 fails because
+3 bricks went down in 4+2 setup.
+
+Fop on mount-1 which is put in frozen list will hang because no codepath will
+move it from frozen list to any other list and the lock will not be retried.
+
+Fix:
+Don't set lock->release to true if lock is not acquired at the time of
+lock-contention-notification

+server.sin_family was set to AF_INET while creating socket connection,

+
+With this patch, sin_family is set by reading the ai_family of

+Subject: [PATCH 296/297] glusterfind: pre command failure on a modify
+
+Label: DOWNSTREAM ONLY
+
+On upstream we have gfid_to_all_paths_using_gfid2path instead of
+gfid_to_path_using_pgfid and so we do not hit this in upstream.
+
+Problem: On a modify, the pre commands runs through the find function.
+where the number of arguments sent mismatches and causes a stderr.
+The mismatch is because of both changelog and brickfind use the find(),
+but the brickfind was alone handled.
+
+Fix: Have handled the additional argument on the changelog side as well.
+Received it as a dummy variable for changelog.

+
+Problem:
+
+Geo-rep session for non-root going faulty.
+
+Solution:
+
+During worker start we do not construct slave url and use 'args.resource_remote'
+which is basically just slave-hostname.
+This works better for root session but fails in non-root session during
+ssh command.
+Using slave url solves this issue.

+Subject: [PATCH 299/302] geo-rep: performance improvement while syncing
+ renames with existing gfid
+
+Problem:
+The bug[1] addresses issue of data inconsistency when handling RENAME with
+existing destination. This fix requires some performance tuning considering
+this issue occurs in heavy rename workload.
+
+Solution:
+If distribution count for master volume is one do not verify op's on
+master and go ahead with rename.
+
+The performance improvement with this patch can only be observed if
+master volume has distribution count one.

+Subject: [PATCH 300/302] cli: remove the warning displayed when remove brick
+ start issued
+
+remove-brick start command gives displays below error:
+
+It is recommended that remove-brick be run with cluster.force-migration
+option disabled to prevent possible data corruption. Doing so will ensure
+that files that receive writes during migration will not be migrated and
+will need to be manually copied after the remove-brick commit operation.
+Please check the value of the option and update accordingly.
+Do you want to continue with your current cluster.force-migration settings? (y/n)
+
+As we are not qualifying cluster.force-migration for 3.5.0,
+we should not display this message. So, removing it.

+Subject: [PATCH 302/302] cluster/ec: prevent filling shd log with "table not
+ found" messages
+
+When self-heal daemon receives an inodelk contention notification, it tries
+to locate the related inode using inode_find() and the inode table owned by
+top-most xlator, which in this case doesn't have any inode table. This causes
+many messages to be logged by inode_find() function because the inode table
+passed is NULL.
+
+This patch prevents this by making sure the inode table is not NULL before
+calling inode_find().

+Subject: [PATCH 308/308] dht: Rebalance causing IO Error - File descriptor in
+ bad state
+
+Problem : When a file is migrated, dht attempts to re-open all open
+          fds on the new cached subvol. Earlier, if dht had not opened the fd,
+          the client xlator would be unable to find the remote fd and would
+          fall back to using an anon fd for the fop. That behavior changed with
+          https://review.gluster.org/#/c/glusterfs/+/15804, causing fops to fail
+          with EBADFD if the fd was not available on the cached subvol.
+          The client xlator returns EBADFD if the remote fd is not found but
+          dht only checks for EBADF before re-opening fds on the new cached subvol.
+
+Solution: Handle EBADFD at dht code path to avoid the issue

+Subject: [PATCH 309/309] geo-rep: Fix config upgrade on non-participating node
+
+After upgrade, if the config files are of old format, it
+gets migrated to new format. Monitor process migrates it.
+Since monitor doesn't run on nodes where bricks are not
+hosted, it doesn't get migrated there. So this patch fixes
+the config upgrade on nodes which doesn't host bricks.
+This happens during config either on get/set/reset.

+Subject: [PATCH 311/313] geo-rep: Fix Permission denied traceback on non root
+ setup
+
+Problem:
+While syncing rename of directory in hybrid crawl, geo-rep
+crashes as below.
+
+Traceback (most recent call last):
+  File "/usr/local/libexec/glusterfs/python/syncdaemon/repce.py", line 118, in worker
+    res = getattr(self.obj, rmeth)(*in_data[2:])
+  File "/usr/local/libexec/glusterfs/python/syncdaemon/resource.py", line 588, in entry_ops

+  File "/usr/local/libexec/glusterfs/python/syncdaemon/syncdutils.py", line 546, in errno_wrap

+
+Cause:
+Conversion of gfid to path for a directory uses readlink on backend
+.glusterfs gfid path. But this fails for non root user with
+permission denied.
+
+Fix:
+Use gfid2path interface to get the path from gfid

+Subject: [PATCH 313/313] extras: Cgroup(CPU/Mem) restriction are not working
+ on gluster process
+
+Problem: After Configure the Cgroup(CPU/MEM) limit to a gluster processes
+         resource(CPU/MEM) limits are not applicable to the gluster
+         processes.Cgroup limits are not applicable because all threads are
+         not moved into a newly created cgroup to apply restriction.
+
+Solution: To move a gluster thread to newly created cgroup change the
+          condition in script

+Subject: [PATCH 320/335] gf-event: Handle unix volfile-servers
+
+Problem:
+glfsheal program uses unix-socket-based volfile server.
+volfile server will be the path to socket in this case.
+gf_event expects this to be hostname in all cases. So getaddrinfo
+will fail on the unix-socket path, events won't be sent in this case.
+
+Fix:
+In case of unix sockets, default to localhost

+
+Problem: After completion of rebalance, if glusterd is restarted,
+rebalance status displays wrong rebalance data size in its output.
+
+Cause: While glusterd restoring the information from /var/lib/glusterd/
+into its memory, glusterd fetches rebalance_data from
+/var/lib/glusterd/vols/volname/node_state.info. This value is
+converted into an integer using atoi(), which is returning
+incorrect value for larger values.
+
+Solution: use sscanf() instead of atoi() to convert string to
+integer(in this case it is unsigned long)

+Subject: [PATCH 323/335] cli: display detailed rebalance info
+
+Problem: When one of the node is down in cluster,
+rebalance status is not displaying detailed
+information.
+
+Cause: In glusterd_volume_rebalance_use_rsp_dict()
+we are aggregating rsp from all the nodes into a
+dictionary and sending it to cli for printing. While
+assigning a index to keys we are considering all the
+peers instead of considering only the peers which are
+up. Because of which, index is not reaching till 1.
+while parsing the rsp cli unable to find status-1
+key in dictionary and going out without printing
+any information.
+
+Solution: The simplest fix for this without much
+code change is to continue to look for other keys
+when status-1 key is not found.

+
+Problem -
+Currently remove-brick commit goes through even though there were files
+that failed to migrate or were skipped. There is no warning raised to the user.
+Solution-
+Add a check in the remove brick staging phase to verify if the status of the
+rebalnce process is complete but there has been failures or some skipped files
+while migration, In this case user will be given a warning and remove-brick
+commit. User will need to use the force option to remove the bricks.

+ healed_sinks
+
+Backport of: https://review.gluster.org/#/c/glusterfs/+/23364/
+
+Problem:
+In a situation where B1 blames B2, B2 blames B1 and B3 doesn't blame
+anything for entry heal, heal will not complete even though we have
+clear source and sinks. This will happen because while doing
+afr_selfheal_find_direction() only the bricks which are blamed by
+non-accused bricks are considered as sinks. Later in
+__afr_selfheal_entry_finalize_source() when it tries to mark all the
+non-sources as sinks it fails to do so because there won't be any
+healed_sinks marked, no witness present and there will be a source.
+
+Fix:
+If there is a source and no healed_sinks, then reset all the locked
+sources to 0 and healed sinks to 1 to do conservative merge.

+Subject: [PATCH 331/335] features/locks: Do special handling for op-version <
+ 3.12.0
+
+Problem:
+Patch https://code.engineering.redhat.com/gerrit/#/c/140080/ diverges from
+its upstream patch(https://review.gluster.org/c/glusterfs/+/20031) in op-version.
+On upstream special-handling happens for version < 3.10.0 whereas for downstream
+special-handling happens for version < 3.12.0.
+    When rebase happened for 3.5.0 from upstream, this downstream specific change
+is missed as there was no special downstream-only patch tracking this difference.
+This leads to I/O errors on upgrade from 3.3.1->3.5.0
+
+Fix:
+Do special handling for op-version < 3.12.0 as in 3.4.x

+The current help show 2 different top commands

+and clubbing into them into a single command.
+
+Current help:
+volume top <VOLNAME> {open|read|write|opendir|readdir|clear}
+[nfs|brick <brick>] [list-cnt <value>] |
+volume top <VOLNAME> {read-perf|write-perf}
+[bs <size> count <count>] [brick <brick>]
+[list-cnt <value>] - volume top operations
+
+Expected help:
+volume top <VOLNAME> {open|read|write|opendir|readdir|clear}
+[nfs|brick <brick>] [list-cnt <value>] | {read-perf|write-perf}
+[bs <size> count <count>] [brick <brick>] [list-cnt <value>]

+Subject: [PATCH 334/335] dht: log getxattr failure for node-uuid at "DEBUG"
+
+There are two ways to fetch node-uuid information from dht.
+
+1 - #define GF_XATTR_LIST_NODE_UUIDS_KEY "trusted.glusterfs.list-node-uuids"
+This key is used by AFR.
+
+2 - #define GF_REBAL_FIND_LOCAL_SUBVOL "glusterfs.find-local-subvol"
+This key is used for non-afr volume type.
+
+We do two getxattr operations. First on the #1 key followed by on #2 if
+getxattr on #1 key fails.
+
+Since the parent function "dht_init_local_subvols_and_nodeuuids" logs failure,
+moving the log-level to DEBUG in dht_find_local_subvol_cbk.

+Subject: [PATCH 337/344] fuse: Set limit on invalidate queue size
+
+If the glusterfs fuse client process is unable to
+process the invalidate requests quickly enough, the
+number of such requests quickly grows large enough
+to use a significant amount of memory.
+We are now introducing another option to set an upper
+limit on these to prevent runaway memory usage.

+
+Problem: In the commit faf5ac13c4ee00a05e9451bf8da3be2a9043bbf2 missed one
+         condition to come out from the loop so after reach the slot_used to

+
+Solution: Correct the code path to avoid the infinite loop

+Subject: [PATCH 341/344] socket: fix error handling
+
+When __socket_proto_state_machine() detected a problem in the size of
+the request or it couldn't allocate an iobuf of the requested size, it
+returned -ENOMEM (-12). However the caller was expecting only -1 in
+case of error. For this reason the error passes undetected initially,
+adding back the socket to the epoll object. On further processing,
+however, the error is finally detected and the connection terminated.
+Meanwhile, another thread could receive a poll_in event from the same
+connection, which could cause races with the connection destruction.
+When this happened, the process crashed.
+
+To fix this, all error detection conditions have been hardened to be
+more strict on what is valid and what not. Also, we don't return
+-ENOMEM anymore. We always return -1 in case of error.
+
+An additional change has been done to prevent destruction of the
+transport object while it may still be needed.

+Date: Tue, 12 Feb 2019 18:33:44 +0530
+Subject: [PATCH 345/346] read-ahead/io-cache: turn off by default
+
+We've found perf xlators io-cache and read-ahead not adding any
+performance improvement. At best read-ahead is redundant due to kernel
+read-ahead and at worst io-cache is degrading the performance for
+workloads that doesn't involve re-read. Given that VFS already have
+both these functionalities, this patch makes these two
+translators turned off by default for native fuse mounts.
+
+For non-native fuse mounts like gfapi (NFS-ganesha/samba) we can have
+these xlators on by having custom profiles.

+Subject: [PATCH 346/346] fuse: degrade logging of write failure to fuse device
+
+Problem:
+
+FUSE uses failures of communicating with /dev/fuse with various
+errnos to indicate in-kernel conditions to userspace. Some of these
+shouldn't be handled as an application error. Also the standard
+POSIX errno description should not be shown as they are misleading
+in this context.
+
+Solution:
+
+When writing to the fuse device, the caller of the respective
+convenience routine can mask those errnos which don't qualify to
+be an error for the application in that context, so then those
+shall be reported at DEBUG level.
+
+The possible non-standard errnos are reported with their
+POSIX name instead of their description to avoid confusion.
+(Eg. for ENOENT we don't log "no such file or directory",
+we log indeed literal "ENOENT".)

+Subject: [PATCH 347/349] tools/glusterfind: handle offline bricks
+
+Problem:
+glusterfind is unable to copy remote output file to local node when a
+remove-brick is in progress on the remote node. After copying remote
+files, in the --full output listing path, a "sort -u" command is run on
+the collected files. However, "sort" exits with an error code if it
+finds any file missing.
+
+Solution:
+Maintain a map of (pid, output file) when the node commands are started
+and remove the mapping for the pid for which the command returns an
+error. Use the list of files present in the map for the "sort" command.

+Subject: [PATCH 348/349] glusterfind: Fix py2/py3 issues
+
+1. In dictionary values(), returns list in py2 and not in py3.
+   So explicitly convert it into list.
+2. xattr module returns values in bytes. So explicitly convert
+   them to str to work both with py2 and py3

+Subject: [PATCH 351/351] server: Mount fails after reboot 1/3 gluster nodes
+
+Problem: At the time of coming up one server node(1x3) after reboot
+client is unmounted.The client is unmounted because a client
+is getting AUTH_FAILED event and client call fini for the graph.The
+client is getting AUTH_FAILED because brick is not attached with a
+graph at that moment
+
+Solution: To avoid the unmounting the client graph throw ENOENT error
+          from server in case if brick is not attached with server at
+          the time of authenticate clients.

+Subject: [PATCH 354/355] core: fix memory pool management races
+
+Objects allocated from a per-thread memory pool keep a reference to it
+to be able to return the object to the pool when not used anymore. The
+object holding this reference can have a long life cycle that could
+survive a glfs_fini() call.
+
+This means that it's unsafe to destroy memory pools from glfs_fini().
+
+Another side effect of destroying memory pools from glfs_fini() is that
+the TLS variable that points to one of those pools cannot be reset for
+all alive threads.  This means that any attempt to allocate memory from
+those threads will access already free'd memory, which is very
+dangerous.
+
+To fix these issues, mem_pools_fini() doesn't destroy pool lists
+anymore. Only at process termination the pools are destroyed.

+Subject: [PATCH 355/355] core: Prevent crash on process termination
+
+A previous patch (ce61da816a) has fixed a use-after-free issue,
+but it doesn't work well when the final cleanup is done at process
+termination because gluster doesn't stop other threads before
+calling exit().
+
+For this reason, the final cleanup is removed to avoid the crash,
+at least until the termination sequence properly stops all gluster
+threads before exiting the program.

+Subject: [PATCH 360/362] rpc: Make ssl log more useful
+
+Currently, ssl_setup_connection_params throws 4 messages for every
+rpc connection that irritates a user while reading the logs. The same
+info we can print in a single log with peerinfo to make it more
+useful.ssl_setup_connection_params try to load dh_param even user
+has not configured it and if a dh_param file is not available it throws
+a failure message.To avoid the message load dh_param only while the user
+has configured it.

+Subject: [PATCH 362/362] write-behind: fix data corruption
+
+There was a bug in write-behind that allowed a previous completed write
+to overwrite the overlapping region of data from a future write.
+
+Suppose we want to send three writes (W1, W2 and W3). W1 and W2 are
+sequential, and W3 writes at the same offset of W2:
+
+    W2.offset = W3.offset = W1.offset + W1.size
+
+Both W1 and W2 are sent in parallel. W3 is only sent after W2 completes.
+So W3 should *always* overwrite the overlapping part of W2.
+
+Suppose write-behind processes the requests from 2 concurrent threads:
+
+    Thread 1                    Thread 2
+
+    <received W1>
+                                <received W2>
+    wb_enqueue_tempted(W1)
+    /* W1 is assigned gen X */
+                                wb_enqueue_tempted(W2)
+                                /* W2 is assigned gen X */
+
+                                wb_process_queue()
+                                  __wb_preprocess_winds()
+                                    /* W1 and W2 are sequential and all
+                                     * other requisites are met to merge
+                                     * both requests. */
+                                    __wb_collapse_small_writes(W1, W2)
+                                    __wb_fulfill_request(W2)
+

+                                   * already fulfilled, wb_inode->gen
+                                   * is not updated. */

+                                wb_do_unwinds()

+                                   * the conflicting W2) and W3 with
+                                   * same gen, so they are interpreted
+                                   * as concurrent writes that do not
+                                   * conflict. */
+                                  __wb_pick_winds() -> W3
+
+                                wb_do_winds()
+                                  STACK_WIND(W3)
+
+    wb_process_queue()
+      /* Eventually W1 will be
+       * ready to be sent */
+      __wb_pick_winds() -> W1
+      __wb_pick_unwinds() -> W1
+        /* Here wb_inode->gen is
+         * incremented. */
+
+    wb_do_unwinds()
+      STACK_UNWIND(W1)
+
+    wb_do_winds()
+      STACK_WIND(W1)
+
+So, as we can see, W3 is sent before W1, which shouldn't happen.
+
+The problem is that wb_inode->gen is only incremented for requests that
+have not been fulfilled but, after a merge, the request is marked as
+fulfilled even though it has not been sent to the brick. This allows
+that future requests are assigned to the same generation, which could
+be internally reordered.
+
+Solution:
+
+Increment wb_inode->gen before any unwind, even if it's for a fulfilled
+request.
+
+Special thanks to Stefan Ring for writing a reproducer that has been
+crucial to identify the issue.

+the layout setxattr fails. This is because the actual lookup fop
+must have been successful to proceed for layout heal. Hence, we could
+not tell if fix-layout failed in rebalance.
+
+Solution: We can check this information in the layout structure that
+whether all the xlators have returned error.

+Subject: [PATCH 369/375] cluster/ec: Return correct error code and log message
+
+In case of readdir was send with an FD on which opendir
+was failed, this FD will be useless and we return it with error.
+For now, we are returning it with EINVAL without logging any
+message in log file.
+
+Return a correct error code and also log the message to improve thing to debug.

+Subject: [PATCH 370/375] dht: Do opendir selectively in gf_defrag_process_dir
+
+Currently opendir is done from the cluster view. Hence, even if
+one opendir is successful, the opendir operation as a whole is considered
+successful.
+
+But since in gf_defrag_get_entry we fetch entries selectively from
+local_subvols, we need to opendir individually on those local subvols
+and keep track of fds separately. Otherwise it is possible that opendir
+failed on one of the subvol and we wind readdirp call on the fd to the
+corresponding subvol, which will ultimately result in EINVAL error.

+Subject: [PATCH 371/375] common-ha: cluster status shows "FAILOVER" when
+ actually HEALTHY
+
+pacemaker devs change the format of the ouput of `pcs status`
+
+Expected to find a line in the format:
+
+    Online: ....
+
+but now it's
+
+    * Online: ...
+
+And the `grep -E "^Online:" no longer finds the list of nodes that
+are online.
+
+Also other lines now have '*' in first few characters of the line
+throwing off `grep -x ...`

+Open behind was not keeping any reference on fd's pending to be
+opened. This makes it possible that a concurrent close and en entry
+fop (unlink, rename, ...) caused destruction of the fd while it
+was still being used.

+Backport of:

+> Change-Id: I0b49f2b58becd0d8874b3d4b14ff8d92a89d02d5

+
+A crash is seen during a reattempt to clean up shards in background
+upon remount. And this happens even on remount (which means a remount
+is no workaround for the crash).
+
+In such a situation, the in-memory base inode object will not be
+existent (new process, non-existent base shard).
+So local->resolver_base_inode will be NULL.
+
+In the event of an error (in this case, of space running out), the
+process would crash at the time of logging the error in the following line -
+
+        gf_msg(this->name, GF_LOG_ERROR, local->op_errno, SHARD_MSG_FOP_FAILED,
+               "failed to delete shards of %s",
+               uuid_utoa(local->resolver_base_inode->gfid));
+
+Fixed that by using local->base_gfid as the source of gfid when
+local->resolver_base_inode is NULL.

+Subject: [PATCH 377/379] syncop: improve scaling and implement more tools
+
+The current scaling of the syncop thread pool is not working properly
+and can leave some tasks in the run queue more time than necessary
+when the maximum number of threads is not reached.
+
+This patch provides a better scaling condition to react faster to
+pending work.
+
+Condition variables and sleep in the context of a synctask have also
+been implemented. Their purpose is to replace regular condition
+variables and sleeps that block synctask threads and prevent other
+tasks to be executed.
+
+The new features have been applied to several places in glusterd.
+
+upstream patch: https://review.gluster.org/#/c/glusterfs/+/24396/

+From d79660ccc65f163e0d9cf91cc13a199bec04d5f1 Mon Sep 17 00:00:00 2001
+From: Xavi Hernandez Juan <xhernandez@redhat.com>
+Date: Wed, 20 May 2020 12:55:43 +0000
+Subject: [PATCH 378/379] Revert "open-behind: fix missing fd reference"
+
+This reverts commit 30cbdf8c06145a0c290da42ecc0a7eae928200b7.
+
+The patch is not complete because there have been some crash reports
+upstream recently after the patch was released. A new patch that should
+cover all corner cases is under review (), but it's a big change and it
+could be risky to backport it without enough testing.
+
+Since there exists a workaround to avoid the problem (disable
+open-behind), for now we revert the patch.
+
+Change-Id: I9cfc55623c33758cf5530b18f03c0d795b0f650b

+Subject: [PATCH 379/379] glusterd: add missing synccond_broadcast()
+
+After the changes in commit 3da22f8cb08b05562a4c6bd2694f2f19199cff7f,
+there was a place where synccond_broadcast() was missing. It could
+cause a hang if another synctask was waiting on the condition variable.

+
+Posix translator returns pre and postbufs in the dict in {F}SETXATTR fops.
+These iatts are further cached at layers like md-cache.
+Shard translator, in its current state, simply returns these values without
+updating the aggregated file size and block-count.
+
+This patch fixes this problem.

+Subject: [PATCH 382/382] features/shard: Aggregate file size, block-count
+ before unwinding removexattr
+
+Posix translator returns pre and postbufs in the dict in {F}REMOVEXATTR fops.
+These iatts are further cached at layers like md-cache.
+Shard translator, in its current state, simply returns these values without
+updating the aggregated file size and block-count.
+
+This patch fixes this problem.

+
+bash [[ ... =~ ... ]] built-in returns _0_ when the regex matches,

+
+If glusterd crashes or goes down abnormally, systemd should
+automatically bring the glusterd up.
+
+With this change, systemd brings glusterd up for atmost 3 times
+within time period of 1 hour. If the limit exceeds, we have to
+start the glusterd manually and reset the failure count using
+systemctl reset-failed.

+Subject: [PATCH 387/449] To fix readdir-ahead memory leak
+
+Glusterfs client process has memory leak if create several files under
+one folder, and delete the folder. According to statedump, the ref
+counts of readdir-ahead is bigger than zero in the inode table.
+
+Readdir-ahead get parent inode by inode_parent in rda_mark_inode_dirty
+when each rda_writev_cbk,the inode ref count of parent folder will be
+increased in inode_parent, but readdir-ahead do not unref it later.
+
+The correction is unref the parent inode at the end of
+rda_mark_inode_dirty.

+Subject: [PATCH 390/449] glusterd: deafult options after volume reset
+
+Problem: default option itransport.address-family is disappered
+in volume info output after a volume reset.
+
+Cause: with 3.8.0 onwards volume option transport.address-family
+has default value, any volume which is created will have this
+option set. So, volume info will show this in its output. But,
+with reset volume, this option is not handled.
+
+Solution: In glusterd_enable_default_options(), we should add this
+option along with other default options. This function is called
+by glusterd_options_reset() with volume reset command.

+Root Cause -
+Since, There is a diff in volfile versions in N1 as compared
+to N2 and N3 therefore glusterd_import_friend_volume() is called.
+glusterd_import_friend_volume() copies the new_volinfo and deletes
+old_volinfo and then calls glusterd_start_bricks().
+glusterd_start_bricks() looks for the volfiles and sends an rpc
+request to glusterfs_handle_attach(). Now, since the volinfo
+has been deleted by glusterd_delete_stale_volume()
+from priv->volumes list before glusterd_start_bricks() and
+glusterd_create_volfiles_and_notify_services() and
+glusterd_list_add_order is called after glusterd_start_bricks(),
+therefore the attach RPC req gets an empty volfile path
+and that causes the brick to crash.
+
+Fix- Call glusterd_list_add_order() and
+glusterd_create_volfiles_and_notify_services before
+glusterd_start_bricks() cal is made in glusterd_import_friend_volume

+Subject: [PATCH 395/449] [Cli] Removing old log rotate command.
+
+The old command for log rotate is still present removing
+it completely. Also adding testcase to test the
+log rotate command with both the old as well as the new command
+and fixing testcase which use the old syntax to use the new
+one.
+
+Code to be removed:
+1. In cli-cmd-volume.c from struct cli_cmd volume_cmds[]:
+{"volume log rotate <VOLNAME> [BRICK]", cli_cmd_log_rotate_cbk,
+ "rotate the log file for corresponding volume/brick"
+ " NOTE: This is an old syntax, will be deprecated from next release."},
+
+2. In cli-cmd-volume.c from cli_cmd_log_rotate_cbk():
+ ||(strcmp("rotate", words[2]) == 0)))
+
+3. In cli-cmd-parser.c from cli_cmd_log_rotate_parse()
+if (strcmp("rotate", words[2]) == 0)
+   volname = (char *)words[3];
+else

+ attach is failed.
+
+We were sending two response back to glusterd when an attach is
+failed. One from the handler function glusterfs_handle_attach and
+another from rpcsvc_check_and_reply_error. It was causing problems
+like ref leaks, transport disconnect etc.

+ disperse volume
+
+Currently when we issue a heal statistics or similar commands
+for disperse volume, it fails with message "Volume is not of
+type replicate." Adding message "this command is supported for
+volumes of type replicate" to reflect supportability and better
+understanding of heal functionality for disperse volumes.

+Subject: [PATCH 401/449] cli: change the warning message
+
+while creating the replica 2 volume or converting
+a volume to replica 2 volume, we issue a warning
+saying "replica 2 volumes are prone to split brain".
+As the support for replica 2 volumes has been deprecated,
+warning message should be changed accordingly to reflect
+the same.

+Subject: [PATCH 403/449] Fix spurious failure in bug-1744548-heal-timeout.t
+
+Script was assuming that the heal would have triggered
+by the time test was executed, which may not be the case.
+It can lead to following failures when the race happens:
+
+...
+18:29:45 not ok  14 [     85/      1] <  26> '[ 331 == 333 ]' -> ''
+...
+18:29:45 not ok  16 [  10097/      1] <  33> '[ 668 == 666 ]' -> ''
+
+Heal on 3rd brick didn't start completely first time the command was executed.
+So the extra count got added to the next profile info.
+
+Fixed it by depending on cumulative stats and waiting until the count is
+satisfied using EXPECT_WITHIN

+Subject: [PATCH 406/449] afr: support split-brain CLI for replica 3
+
+Patch in upstream master: https://review.gluster.org/#/c/glusterfs/+/23502/
+
+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).
+

+Subject: [PATCH 408/449] geo-rep: Fix ssh-port validation
+
+If non-standard ssh-port is used, Geo-rep can be configured to use ssh port
+by using config option, the value should be in allowed port range and non negative.
+
+At present it can accept negative value and outside allowed port range which is incorrect.
+
+Many Linux kernels use the port range 32768 to 61000.
+IANA suggests it should be in the range 1 to 2^16 - 1, so keeping the same.
+
+$ gluster volume geo-replication master 127.0.0.1::slave config ssh-port -22
+geo-replication config updated successfully
+$ gluster volume geo-replication master 127.0.0.1::slave config ssh-port 22222222
+geo-replication config updated successfully
+
+This patch fixes the above issue and have added few validations around this
+in test cases.

+Subject: [PATCH 410/449] afr: prevent spurious entry heals leading to gfid
+ split-brain
+
+Problem:
+In a hyperconverged setup with granular-entry-heal enabled, if a file is
+recreated while one of the bricks is down, and an index heal is triggered
+(with the brick still down), entry-self heal was doing a spurious heal
+with just the 2 good bricks. It was doing a post-op leading to removal
+of the filename from .glusterfs/indices/entry-changes as well as
+erroneous setting of afr xattrs on the parent. When the brick came up,
+the xattrs were cleared, resulting in the renamed file not getting
+healed and leading to gfid split-brain and EIO on the mount.
+
+Fix:
+Proceed with entry heal only when shd can connect to all bricks of the replica,
+just like in data and metadata heal.

+Subject: [PATCH 414/449] cluster-syncop: avoid duplicate unlock of
+ inodelk/entrylk
+
+When using ec, there are many spam messages in brick and client
+logs files.
+
+When shd does entry heal, it takes lock on a directory using
+cluster_tiebreaker_inodelk(). If it does not get lock on all
+the bricks because other clients has got lock on some bricks,
+it will unlock the locks on those bricks which it got and then
+will try blocking locks (If any one of the previous was successful).
+
+The problem come here. In case we do not get locks on all the
+required bricks, we are sending unlock request twice on those
+bricks where we got the locks.

+Subject: [PATCH 415/449] dht: Fix stale-layout and create issue
+
+Problem: With lookup-optimize set to on by default, a client with
+stale-layout can create a new file on a wrong subvol. This will lead to
+possible duplicate files if two different clients attempt to create the
+same file with two different layouts.
+
+Solution: Send in-memory layout to be cross checked at posix before
+commiting a "create". In case of a mismatch, sync the client layout with
+that of the server and attempt the create fop one more time.
+
+test: Manual, testcase(attached)

+Subject: [PATCH 416/449] tests: fix spurious failure of
+ bug-1402841.t-mt-dir-scan-race.t
+
+Upstream patch: https://review.gluster.org/23352
+
+Problem:
+Since commit 600ba94183333c4af9b4a09616690994fd528478, shd starts
+healing as soon as it is toggled from disabled to enabled. This was
+causing the following line in the .t to fail on a 'fast' machine (always
+on my laptop and sometimes on the jenkins slaves).
+
+EXPECT_NOT "^0$" get_pending_heal_count $V0
+
+because by the time shd was disabled, the heal was already completed.
+
+Fix:
+Increase the no. of files to be healed and make it a variable called
+FILE_COUNT, should we need to bump it up further because the machines
+become even faster. Also created pending metadata heals to increase the
+time taken to heal a file.

+Subject: [PATCH 418/449] md-cache: avoid clearing cache when not necessary
+
+mdc_inode_xatt_set() blindly cleared current cache when dict was not
+NULL, even if there was no xattr requested.
+
+This patch fixes this by only calling mdc_inode_xatt_set() when we have
+explicitly requested something to cache.

+From b9b479de2a7fd1c5eefa7aa1142e0a39e0c96ca9 Mon Sep 17 00:00:00 2001
+From: Xavi Hernandez <xhernandez@redhat.com>
+Date: Sun, 1 Mar 2020 19:49:04 +0100
+Subject: [PATCH 419/449] cluster/afr: fix race when bricks come up
+
+The was a problem when self-heal was sending lookups at the same time
+that one of the bricks was coming up. In this case there was a chance
+that the number of 'up' bricks changes in the middle of sending the
+requests to subvolumes which caused a discrepancy in the expected
+number of replies and the actual number of sent requests.
+
+This discrepancy caused that AFR continued executing requests before
+all requests were complete. Eventually, the frame of the pending
+request was destroyed when the operation terminated, causing a use-
+after-free issue when the answer was finally received.
+
+In theory the same thing could happen in the reverse way, i.e. AFR
+tries to wait for more replies than sent requests, causing a hang.

+Subject: [PATCH 422/449] cluster/afr: Prioritize ENOSPC over other errors
+
+Backport of: https://review.gluster.org/#/c/glusterfs/+/24477/
+
+Problem:
+In a replicate/arbiter volume if file creations or writes fails on
+quorum number of bricks and on one brick it is due to ENOSPC and
+on other brick it fails for a different reason, it may fail with
+errors other than ENOSPC in some cases.
+
+Fix:
+Prioritize ENOSPC over other lesser priority errors and do not set
+op_errno in posix_gfid_set if op_ret is 0 to avoid receiving any
+error_no which can be misinterpreted by __afr_dir_write_finalize().
+
+Also removing the function afr_has_arbiter_fop_cbk_quorum() which
+might consider a successful reply form a single brick as quorum
+success in some cases, whereas we always need fop to be successful
+on quorum number of bricks in arbiter configuration.

+Subject: [PATCH 423/449] ctime: Fix ctime inconsisteny with utimensat
+
+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.

+Subject: [PATCH 424/449] afr: make heal info lockless
+
+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.

+Date: Fri, 5 Jun 2020 14:28:11 +0530
+Subject: [PATCH 425/449] tests: Fix spurious self-heald.t failure
+
+Problem:
+heal-info code assumes that all indices in xattrop directory
+definitely need heal. There is one corner case.
+The very first xattrop on the file will lead to adding the
+gfid to 'xattrop' index in fop path and in _cbk path it is
+removed because the fop is zero-xattr xattrop in success case.
+These gfids could be read by heal-info and shown as needing heal.
+
+Fix:
+Check the pending flag to see if the file definitely needs or
+not instead of which index is being crawled at the moment.

+Subject: [PATCH 426/449] geo-rep: Fix for "Transport End Point not connected"
+ issue
+
+problem: Geo-rep gsyncd process mounts the master and slave volume
+         on master nodes and slave nodes respectively and starts
+         the sync. But it doesn't wait for the mount to be in ready
+         state to accept I/O. The gluster mount is considered to be
+         ready when all the distribute sub-volumes is up. If the all
+         the distribute subvolumes are not up, it can cause ENOTCONN
+         error, when lookup on file comes and file is on the subvol
+         that is down.
+
+solution: Added a Virtual Xattr "dht.subvol.status" which returns "1"
+          if all subvols are up and "0" if all subvols are not up.
+          Geo-rep then uses this virtual xattr after a fresh mount, to
+          check whether all subvols are up or not and then starts the
+          I/O.

+Subject: [PATCH 431/449] glusterd: check for same node while adding bricks in
+ disperse volume
+
+The optimal way for configuring disperse and replicate volumes
+is to have all bricks in different nodes.
+
+During create operation it fails saying it is not optimal, user
+must use force to over-ride this behavior. Implementing same
+during add-brick operation to avoid situation where all the added
+bricks end up from same host. Operation will error out accordingly.
+and this can be over-ridden by using force same as create.

+Subject: [PATCH 432/449] glusterd: Fix coverity defects & put coverity
+ annotations
+
+Along with fixing few defect, put the required annotations for the defects which
+are marked ignore/false positive/intentional as per the coverity defect sheet.
+This should avoid the per component graph showing many defects as open in the
+coverity glusterfs web page.

+Subject: [PATCH 433/449] socket: Resolve ssl_ctx leak for a brick while only
+ mgmt SSL is enabled
+
+Problem: While only mgmt SSL is enabled for a brick process use_ssl flag
+         is false for a brick process and socket api's cleanup ssl_ctx only
+         while use_ssl and ssl_ctx both are valid
+
+Solution: To avoid a leak check only ssl_ctx, if it is valid cleanup
+          ssl_ctx

+Subject: [PATCH 438/449] dht - sparse files rebalance enhancements
+
+Currently data migration in rebalance reads sparse file sequentially,
+disregarding which segments are holes and which are data. This can lead
+to extremely long migration time for large sparse file.
+Data migration mechanism needs to be enhanced so only data segments are
+read and migrated. This can be achieved using lseek to seek for holes
+and data in the file.
+This enhancement is a consequence of

+Subject: [PATCH 439/449] cluster/afr: Delay post-op for fsync
+
+Problem:
+AFR doesn't delay post-op for fsync fop. For fsync heavy workloads
+this leads to un-necessary fxattrop/finodelk for every fsync leading
+to bad performance.
+
+Fix:
+Have delayed post-op for fsync. Add special flag in xdata to indicate
+that afr shouldn't delay post-op in cases where either the
+process will terminate or graph-switch would happen. Otherwise it leads
+to un-necessary heals when the graph-switch/process-termination
+happens before delayed-post-op completes.

+Subject: [PATCH 441/449] fuse: occasional logging for fuse device 'weird'
+ write errors
+
+This change is a followup to
+I510158843e4b1d482bdc496c2e97b1860dc1ba93.
+
+In referred change we pushed log messages about 'weird'
+write errors to fuse device out of sight, by reporting
+them at Debug loglevel instead of Error (where
+'weird' means errno is not POSIX compliant but having
+meaningful semantics for FUSE protocol).
+
+This solved the issue of spurious error reporting.
+And so far so good: these messages don't indicate
+an error condition by themselves. However, when they
+come in high repetitions, that indicates a suboptimal
+condition which should be reported.[1]
+
+Therefore now we shall emit a Warning if a certain
+errno occurs a certain number of times[2] as the
+outcome of a write to the fuse device.
+
+___
+[1] typically ENOENTs and ENOTDIRs accumulate
+when glusterfs' inode invalidation lags behind
+the kernel's internal inode garbage collection
+(in this case above errnos mean that the inode
+which we requested to be invalidated is not found
+in kernel). This can be mitigated with the
+invalidate-limit command line / mount option,
+cf. bz#1732717.
+
+[2] 256, as of the current implementation.

+Subject: [PATCH 442/449] fuse: correctly handle setxattr values
+
+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.

+From dc03340654d921916ac3890d713fc84ef4bb1e28 Mon Sep 17 00:00:00 2001
+From: Mohit Agrawal <moagrawal@redhat.com>
+Date: Sat, 29 Sep 2018 13:15:35 +0530
+Subject: [PATCH 445/449] feature/changelog: Avoid thread creation if xlator is
+ not enabled
+
+Problem:
+Changelog creates threads even if the changelog is not enabled
+
+Background:
+Changelog xlator broadly does two things
+  1. Journalling - Cosumers are geo-rep and glusterfind
+  2. Event Notification for registered events like (open, release etc) -
+     Consumers are bitrot, geo-rep
+
+The existing option "changelog.changelog" controls journalling and
+there is no option to control event notification and is enabled by
+default. So when bitrot/geo-rep is not enabled on the volume, threads
+and resources(rpc and rbuf) related to event notifications consumes
+resources and cpu cycle which is unnecessary.
+
+Solution:
+The solution is to have two different options as below.
+ 1. changelog-notification : Event notifications
+ 2. changelog : Journalling
+
+This patch introduces the option "changelog-notification" which is
+not exposed to user. When either bitrot or changelog (journalling)
+is enabled, it internally enbales 'changelog-notification'. But
+once the 'changelog-notification' is enabled, it will not be disabled
+for the life time of the brick process even after bitrot and changelog
+is disabled. As of now, rpc resource cleanup has lot of races and is
+difficult to cleanup cleanly. If allowed, it leads to memory leaks
+and crashes on enable/disable of bitrot or changelog (journal) in a
+loop. Hence to be safer, the event notification is not disabled within
+lifetime of process once enabled.

+Subject: [PATCH 446/449] bitrot: Make number of signer threads configurable
+
+The number of signing process threads (glfs_brpobj)
+is set to 4 by default. The recommendation is to set
+it to number of cores available. This patch makes it
+configurable as follows
+
+gluster vol bitrot <volname> signer-threads <count>

+Subject: [PATCH 447/449] core[brick_mux]: brick crashed when creating and
+ deleting volumes over time
+
+Problem: In brick_mux environment, while volumes are created/stopped in a loop
+         after running a long time the main brick is crashed.The brick is crashed
+         because the main brick process was not cleaned up memory for all objects
+         at the time of detaching a volume.
+         Below are the objects that are missed at the time of detaching a volume
+         1) xlator object for a brick graph
+         2) local_pool for posix_lock xlator
+         3) rpc object cleanup at quota xlator
+         4) inode leak at brick xlator
+
+Solution: To avoid the crash resolve all leak at the time of detaching a brick

+Subject: [PATCH 448/449] Posix: Use simple approach to close fd
+
+Problem: posix_release(dir) functions add the fd's into a ctx->janitor_fds
+         and janitor thread closes the fd's.In brick_mux environment it is
+         difficult to handle race condition in janitor threads because brick
+         spawns a single janitor thread for all bricks.
+
+Solution: Use synctask to execute posix_release(dir) functions instead of
+          using background a thread to close fds.

+Subject: [PATCH 449/449] test: Test case brick-mux-validation-in-cluster.t is
+ failing on RHEL-8
+
+Brick process are not properly attached on any cluster node while
+some volume options are changed on peer node and glusterd is down on
+that specific node.
+
+Solution: At the time of restart glusterd it got a friend update request
+from a peer node if peer node having some changes on volume.If the brick
+process is started before received a friend update request in that case
+brick_mux behavior is not workingproperly. All bricks are attached to
+the same process even volumes options are not the same. To avoid the
+issue introduce an atomic flag volpeerupdate and update the value while
+glusterd has received a friend update request from peer for a specific
+volume.If volpeerupdate flag is 1 volume is started by
+glusterd_import_friend_volume synctask

+
+Problem: While backporting a change from master
+the changes related to tier were removed. This started affecting

+to downstream left this usecase messed up as we still support tier.
+patch that caused this: https://code.engineering.redhat.com/gerrit/#/c/202647/2
+
+Fix: add the condition back for tier pause to work.

+Reason: with commit a113d93 we are checking brick order while
+doing add-brick operation for replica and disperse volumes. If
+replica count or disperse count is not mentioned in the command,
+the dict get is failing and resulting add-brick operation failure.

+Subject: [PATCH 454/456] features/locks: avoid use after freed of frame for
+ blocked lock
+
+The fop contains blocked lock may use freed frame info when other
+unlock fop has unwind the blocked lock.
+
+Because the blocked lock is added to block list in inode lock(or
+other lock), after that, when out of the inode lock, the fop
+contains the blocked lock should not use it.

+Subject: [PATCH 455/456] locks: prevent deletion of locked entries
+
+To keep consistency inside transactions started by locking an entry or
+an inode, this change delays the removal of entries that are currently
+locked by one or more clients. Once all locks are released, the removal
+is processed.
+
+It has also been improved the detection of stale inodes in the locking
+code of EC.
+
+>Upstream patch - https://review.gluster.org/#/c/glusterfs/+/20025/
+>Fixes: #990

+Subject: [PATCH 457/465] cluster/ec: Improve detection of new heals
+
+When EC successfully healed a directory it assumed that maybe other
+entries inside that directory could have been created, which could
+require additional heal cycles. For this reason, when the heal happened
+as part of one index heal iteration, it triggered a new iteration.
+
+The problem happened when the directory was healthy, so no new entries
+were added, but its index entry was not removed for some reason. In
+this case self-heal started and endless loop healing the same directory
+continuously, cause high CPU utilization.
+
+This patch improves detection of new files added to the heal index so
+that a new index heal iteration is only triggered if there is new work
+to do.

+Subject: [PATCH 458/465] features/bit-rot-stub: clean the mutex after
+ cancelling the signer thread
+
+When bit-rot feature is disabled, the signer thread from the bit-rot-stub
+xlator (the thread which performs the setxattr of the signature on to the
+disk) is cancelled. But, if the cancelled signer thread had already held
+the mutex (&priv->lock) which it uses to monitor the queue of files to
+be signed, then the mutex is never released. This creates problems in
+future when the feature is enabled again. Both the new instance of the
+signer thread and the regular thread which enqueues the files to be
+signed will be blocked on this mutex.
+
+So, as part of cancelling the signer thread, unlock the mutex associated
+with it as well using pthread_cleanup_push and pthread_cleanup_pop.

+Subject: [PATCH 459/465] features/bit-rot: Unconditionally sign the files
+ during oneshot crawl
+
+Currently bit-rot feature has an issue with disabling and reenabling it
+on the same volume. Consider enabling bit-rot detection which goes on to
+crawl and sign all the files present in the volume. Then some files are
+modified and the bit-rot daemon goes on to sign the modified files with
+the correct signature. Now, disable bit-rot feature. While, signing and
+scrubbing are not happening, previous checksums of the files continue to
+exist as extended attributes. Now, if some files with checksum xattrs get
+modified, they are not signed with new signature as the feature is off.
+
+At this point, if the feature is enabled again, the bit rot daemon will
+go and sign those files which does not have any bit-rot specific xattrs
+(i.e. those files which were created after bit-rot was disabled). Whereas
+the files with bit-rot xattrs wont get signed with proper new checksum.
+At this point if scrubber runs, it finds the on disk checksum and the actual
+checksum of the file to be different (because the file got modified) and
+marks the file as corrupted.
+
+FIX:
+
+The fix is to unconditionally sign the files when the bit-rot daemon
+comes up (instead of skipping the files with bit-rot xattrs).

+Subject: [PATCH 460/465] cluster/ec: Remove stale entries from indices/xattrop
+ folder
+
+Problem:
+If a gfid is present in indices/xattrop folder while
+the file/dir is actaully healthy and all the xattrs are healthy,
+it causes lot of lookups by shd on an entry which does not need
+to be healed.
+This whole process eats up lot of CPU usage without doing meaningful
+work.
+
+Solution:
+Set trusted.ec.dirty xattr of the entry so that actual heal process
+happens and at the end of it, during unset of dirty, gfid enrty from
+indices/xattrop will be removed.

+Subject: [PATCH 462/465] Issue with gf_fill_iatt_for_dirent
+
+In "gf_fill_iatt_for_dirent()", while calculating inode_path for loc,
+the inode should be of parent's. Instead it is loc.inode which results in error
+ and eventually lookup/readdirp fails.
+
+This patch fixes the same.
+
+This is backport of below mainstream fix :

+Subject: [PATCH 463/465] cluster/ec: Change handling of heal failure to avoid
+ crash
+
+Problem:
+ec_getxattr_heal_cbk was called with NULL as second argument
+in case heal was failing.
+This function was dereferencing "cookie" argument which caused crash.
+
+Solution:
+Cookie is changed to carry the value that was supposed to be
+stored in fop->data, so even in the case when fop is NULL in error
+case, there won't be any NULL dereference.
+
+Thanks to Xavi for the suggestion about the fix.

+Subject: [PATCH 464/465] storage/posix: Remove nr_files usage
+
+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.

+Subject: [PATCH 465/465] posix: Implement a janitor thread to close fd
+
+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

+Subject: [PATCH 466/466] cluster/ec: Change stale index handling
+
+Problem:
+Earlier approach is setting dirty bit which requires extra heal
+
+Fix:
+Send zero-xattrop which deletes stale index without any need
+for extra heal.

+Subject: [PATCH 472/473] geo-rep: gluster_shared_storage fails to automount on
+ node reboot on rhel 8.
+
+Issue: On reboot, all the mounts get wiped out.
+       Only the mounts mentioned in /etc/fstab  automatically gets mounted
+       during boot/reboot.
+
+       But /etc/fstab complains on not getting a canonical path
+       (it gets path containing a symlink)
+       This is because the gluster_shared_storage, is mounted to
+       /var/run which is symlink to /run. This is a general practice
+       followed by most operating systems.
+
+       [root@ ~]# ls -lsah /var/run
+       0 lrwxrwxrwx. 1 root root 6 Jul 22 19:39 /var/run -> ../run
+
+Fix:   Mount gluster_shared_storage on /run.
+       (Also It is seen that /var/run is mostly
+       used by old or legacy systems, thus it is a good practice to
+       update /var/run to /run)

+
+Problem: add-brick operation fails with multiple bricks on same

+
+This was happening because of extra runs in a loop to compare
+hostnames and if bricks supplied were less than "replica" count,
+the bricks will get compared to itself resulting in above error.

+Subject: [PATCH 476/478] mount/fuse: use cookies to get fuse-interrupt-record
+ instead of xdata
+
+Problem:
+On executing tests/features/flock_interrupt.t the following error log
+appears
+[2020-06-16 11:51:54.631072 +0000] E
+[fuse-bridge.c:4791:fuse_setlk_interrupt_handler_cbk] 0-glusterfs-fuse:
+interrupt record not found
+
+This happens because fuse-interrupt-record is never sent on the wire by
+getxattr fop and there is no guarantee that in the cbk it will be
+available in case of failures.
+
+Fix:
+wind getxattr fop with fuse-interrupt-record as cookie and recover it
+in the cbk

+Subject: [PATCH 478/478] DHT - Fixing rebalance failure on issuing stop
+ command
+
+Issuing a stop command for an ongoing rebalance process results in an error.
+This issue was brought up in https://bugzilla.redhat.com/1286171 and a patch
+(https://review.gluster.org/24103/) was submitted to resolve the issue.
+
+However the submitted patch resolved only part of the
+problem by reducing the number of log messages that were printed (since
+rebalnace is currently a recursive process, an error message was printed
+for every directory) but didn't fully resolve the root cause for the
+failure.
+
+This patch fixes the issue by modifying the code-path which handles the
+termination of the rebalance process by issuing a stop command.

+
+Upon issuing rebalance stop command, the status of rebalance is being

+
+This fix ensures rebalance reports it's status only once and that the

+Subject: [PATCH 483/511] afr: more quorum checks in lookup and new entry
+ marking
+
+Problem: See upstream github issue for details.
+
+Fix:
+-In lookup if the entry exists in 2 out of 3 bricks, don't fail the
+lookup with ENOENT just because there is an entrylk on the parent.
+Consider quorum before deciding.
+
+-If entry FOP does not succeed on quorum no. of bricks, do not perform
+new entry mark.

+Subject: [PATCH 484/511] glusterd: rebalance status displays stats as 0 after
+ reboot
+
+problem: while the rebalance is in progress, if a node is
+rebooted rebalance v status shows the stats of this node as
+0 once the node is back.
+
+Reason: when the node is rebooted, once it is back
+glusterd_volume_defrag_restart() starts the rebalance and
+creates the rpc. but due to some race, rebalance process is
+sending disconnect event, so rpc object is getting destroyed. As
+the rpc object is null, request for fetching the latest stats is
+not sent to rebalance process. and stats are shows as default values
+which is 0.
+
+Solution: When the rpc object null, we should create the rpc if the
+rebalance process is up. so that request can be sent to rebalance
+process using the rpc.

+Subject: [PATCH 485/511] cli-rpc: conditional init of global quota rpc (#1578)
+
+Issue: It is seem that the initialization of rpc to
+connect with quotad is done in every glusterfs cli command,
+irrespective of whether the quota feature is enabled or disabled.
+This seems to be an overkill.
+
+Code change: The file /var/run/quotad/quotad.pid is present
+signals that quotad is enabled. Hence we can put a conditional
+check for seeing when this file exists and if it doesn't we
+just skip over the initialization of the global quotad rpc.
+
+This will go on to reduce the extra rpc calls and operations
+being performed in the kernel space.

+Issue: The satus of the brick as tracked by glusterd is

+keeps on trying to reconnect ( rpc layer ) but it fails.
+
+Code change: Rather than registering the rpc connection
+with the help of the given sockfilepath which is not
+even present as it keeps on reconnecting, why not log
+this as an error and not try to reconnect using the
+non-existing sock file path.

+
+Issue: The logging is being done in the same file
+even after the logrotate utility has changed the file.
+This causes the logfile to grow indefinitely.
+
+Code Changes: Using the WatchedFileHandler class instead
+of FileHandler class. This watches the file it is logging
+into and if the file changes, it is closed and reopened
+using the file name. Hence after file rotate, a new file
+will be used for logging instead of continuing with
+the same old file.

+Subject: [PATCH 488/511] glusterd/afr: enable granular-entry-heal by default
+
+XXXXXXXXXXXXXXXXXXX
+    IMPORTANT:
+XXXXXXXXXXXXXXXXXXXX
+I see that for rhgs-3.5.3, GD_OP_VERSION_MAX is GD_OP_VERSION_7_0. Since
+this patch should only act on new volumes in rhgs-3.5.4, I am bumping
+the op-version to GD_OP_VERSION_7_1. In glusterfs upstream, the patch
+acts only if op-version >= GD_OP_VERSION_9_0 as seen in the commit
+messae below.
+
+Upstream patch details:
+/------------------------------------------------------------------------------/
+1. The option has been enabled and tested for quite some time now in RHHI-V
+downstream and I think it is safe to make it 'on' by default. Since it
+is not possible to simply change it from 'off' to 'on' without breaking
+rolling upgrades, old clients etc., I have made it default only for new volumes
+starting from op-verison GD_OP_VERSION_9_0.
+
+Note: If you do a volume reset, the option will be turned back off.
+This is okay as the dir's gfid will be captured in 'xattrop' folder  and heals
+will proceed. There might be stale entries inside entry-changes' folder,
+which will be removed when we enable the option again.
+
+2. I encountered a cust. issue where entry heal was pending on a dir. with
+236436 files in it and the glustershd.log output was just stuck at
+"performing entry selfheal", so I have added logs to give us
+more info in DEBUG level about whether entry heal and data heal are
+progressing (metadata heal doesn't take much time). That way, we have a
+quick visual indication to say things are not 'stuck' if we briefly
+enable debug logs, instead of taking statedumps or checking profile info
+etc.

+Subject: [PATCH 489/511] glusterd: fix bug in enabling granular-entry-heal
+
+Upstream patch details:
+/------------------------------------------------------------------------------/
+commit f5e1eb87d4af44be3b317b7f99ab88f89c2f0b1a meant to enable  the
+volume option only for replica volumes but inadvertently enabled
+it for all volume types. Fixing it now.
+
+Also found a bug in glusterd where disabling the option on plain
+distribute was succeeding even though setting it in the fist place
+fails. Fixed that too.

+Subject: [PATCH 490/511] Segmentation fault occurs during truncate
+
+Problem:
+Segmentation fault occurs when bricks are nearly full 100% and in
+parallel truncate of a file is attempted (No space left on device).
+Prerequicite is that performance xlators are activated
+(read-ahead, write-behind etc)
+while stack unwind of the frames following an error responce
+from brick (No space left on device) frame->local includes a memory
+location that is not allocated via mem_get but via calloc.
+The destroyed frame is always ra_truncate_cbk winded from ra_ftruncate
+and the inode ptr is copied to the frame local in the wb_ftruncate.
+
+Fix:
+extra check is added for the pool ptr

+Subject: [PATCH 491/511] glusterd: mount directory getting truncated on
+ mounting shared_storage
+
+Issue:
+In case of a user created volume the mount point
+is the brick path 'ex: /data/brick' but in case of
+shared_storage the mount point is '/'.So, here
+we increment the array by one so as to get the exact
+path of brick without '/', which works fine for other
+volumes as the pointer of the brick_dir variable is
+at '/', but for shared_storage it is at 'v'(where v is
+starting letter of 'var' directory). So, on incrementing
+the path we get in case of shared_storage starts from
+'ar/lib/glusterd/...'
+
+Fix:
+Only, increment the pointer if the current position is '/',
+else the path will be wrong.
+

+Subject: [PATCH 493/511] geo-rep: Note section is required for ignore_deletes
+
+There exists a window of 15 sec, where the deletes are picked up
+by history crawl when the ignore_deletes is set to true.
+And it eventually deletes the file/s from slave which is/are not
+supposed to be deleted. Though it is working as per design, a
+note regarding this is needed.
+
+Added a warning message indicating the same.
+Also logged info when the worker restarts after ignore-deletes
+option set.

+Subject: [PATCH 494/511] glusterd: start the brick on a different port
+
+Problem: brick fails to start when the port provided by
+glusterd is in use by any other process
+
+Solution: glusterd should check errno set by runner_run()
+and if it is set to EADDRINUSE, it should allocate a new
+port to the brick and try to start it again.
+
+Previously ret value is checked instead of errno, so the
+retry part never executed. Now, we initialize errno to 0
+before calling runner framework. and afterwards store the
+errno into ret to avoid modification of errno in subsequent
+function calls.

+Subject: [PATCH 495/511] geo-rep: descriptive message when worker crashes due
+ to EIO
+
+With this patch now you can notice log if it is due to EIO:
+
+[2020-03-16 16:24:48.293837] E [syncdutils(worker /bricks/brick1/mbr3):348:log_raise_exception] <top>: Getting "Input/Output error" is most likely due to a. Brick is down or b. Split brain issue.
+[2020-03-16 16:24:48.293915] E [syncdutils(worker /bricks/brick1/mbr3):352:log_raise_exception] <top>: This is expected as per design to keep the consistency of the file system. Once the above issue is resolved geo-rep would automatically proceed further.

+Problem:
+The issue is being hit during hybrid mode while handling rename on slave.
+In this special case the rename is recorded as mkdir and geo-rep process it

+Subject: [PATCH 500/511] features/shard: Convert shard block indices to uint64
+
+This patch fixes a crash in FOPs that operate on really large sharded
+files where number of participant shards could sometimes exceed
+signed int32 max.
+
+The patch also adds GF_ASSERTs to ensure that number of participating
+shards is always greater than 0 for files that do have more than one
+shard.

+Subject: [PATCH 502/511] dht - fixing a permission update issue
+
+When bringing back a downed brick and performing lookup from the client
+side, the permission on said brick aren't updated on the first lookup,
+but only on the second.
+
+This patch modifies permission update logic so the first lookup will
+trigger a permission update on the downed brick.
+
+LIMITATIONS OF THE PATCH:
+As the choice of source depends on whether the directory has layout or not.
+Even the directories on the newly added brick will have layout xattr[zeroed], but the same is not true for a root directory.
+Hence, in case in the entire cluster only the newly added bricks are up [and others are down], then any change in permission during this time will be overwritten by the older permissions when the cluster is restarted.

+Subject: [PATCH 503/511] gfapi: Suspend synctasks instead of blocking them
+
+There are certain conditions which blocks the current
+execution thread (like waiting on mutex lock or condition
+variable or I/O response). In such cases, if it is a
+synctask thread, we should suspend the task instead
+of blocking it (like done in SYNCOP using synctask_yield)
+
+This is to avoid deadlock like the one mentioned below -
+
+1) synctaskA sets fs->migration_in_progress to 1 and
+   does I/O (LOOKUP)
+2) Other synctask threads wait for fs->migration_in_progress
+  to be reset to 0 by synctaskA and hence blocked
+3) but synctaskA cannot resume as all synctask threads are blocked
+   on (2).
+
+Note: this same approach is already used by few other components
+like syncbarrier etc.

+Subject: [PATCH 504/511] io-stats: Configure ios_sample_buf_size based on
+ sample_interval value (#1574)
+
+io-stats xlator declares a ios_sample_buf_size 64k object(10M) per xlator
+but in case of sample_interval is 0 this big buffer is not required so
+declare the default value only while sample_interval is not 0.The new
+change would be helpful to reduce RSS size for a brick and shd process
+while the number of volumes are huge.

+
+Currently trash xlator create a inode table(1M) even if
+feature is not enabled.In brick_mux environment while 250
+bricks are attached with a single brick process and feature
+is not enable brick process increase RSS size unnecessarily.
+
+Solution: Create inode_table only while a feature is enabled.
+The patch reduces 250M RSS size per brick process
+if trash feature is not enabled.

+Subject: [PATCH 506/511] posix: Attach a posix_spawn_disk_thread with
+ glusterfs_ctx (#1595)
+
+Currently posix xlator spawns posix_disk_space_threads per brick and in
+case of brick_mux environment while glusterd attached bricks at maximum
+level(250) with a single brick process in that case 250 threads are
+spawned for all bricks and brick process memory size also increased.
+
+Solution: Attach a posix_disk_space thread with glusterfs_ctx to
+          spawn a thread per process basis instead of spawning a per brick
+

+From b3a17b67a69142eef1b4adde3409d5e54dda1e0b Mon Sep 17 00:00:00 2001
+From: Amar Tumballi <amarts@redhat.com>
+Date: Sat, 9 Feb 2019 13:23:06 +0530
+Subject: [PATCH 507/511] inode: make critical section smaller
+
+do all the 'static' tasks outside of locked region.
+
+* hash_dentry() and hash_gfid() are now called outside locked region.
+* remove extra __dentry_hash exported in libglusterfs.sym
+* avoid checks in locked functions, if the check is done in calling
+  function.
+* implement dentry_destroy(), which handles freeing of dentry separately,
+  from that of dentry_unset (which takes care of separating dentry from
+  inode, and table)
+

+From: Csaba Henk <csaba@redhat.com>
+Date: Fri, 17 Jul 2020 11:33:36 +0200
+Subject: [PATCH 508/511] fuse: fetch arbitrary number of groups from
+ /proc/[pid]/status
+
+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().

+Subject: [PATCH 509/511] core: configure optimum inode table hash_size for shd
+
+In brick_mux environment a shd process consume high memory.
+After print the statedump i have found it allocates 1M per afr xlator
+for all bricks.In case of configure 4k volumes it consumes almost total
+6G RSS size in which 4G consumes by inode_tables
+
+[cluster/replicate.test1-replicate-0 - usage-type gf_common_mt_list_head memusage]
+size=1273488
+num_allocs=2
+max_size=1273488
+max_num_allocs=2
+total_allocs=2
+
+inode_new_table function allocates memory(1M) for a list of inode and dentry hash.
+For shd lru_limit size is 1 so we don't need to create a big hash table so to reduce
+RSS size for shd process pass optimum bucket count at the time of creating inode_table.

+Subject: [PATCH 510/511] glusterd[brick_mux]: Optimize friend handshake code
+ to avoid call_bail (#1614)
+
+During glusterd handshake glusterd received a volume dictionary
+from peer end to compare the own volume dictionary data.If the options
+are differ it sets the key to recognize volume options are changed
+and call import syntask to delete/start the volume.In brick_mux
+environment while number of volumes are high(5k) the dict api in function
+glusterd_compare_friend_volume takes time because the function
+glusterd_handle_friend_req saves all peer volume data in a single dictionary.
+Due to time taken by the function glusterd_handle_friend RPC requests receives
+a call_bail from a peer end gluster(CLI) won't be able to show volume status.
+
+Solution: To optimize the code done below changes
+1) Populate a new specific dictionary to save the peer end version specific
+   data so that function won't take much time to take the decision about the
+   peer end has some volume updates.
+2) In case of volume has differ version set the key in status_arr instead
+   of saving in a dictionary to make the operation is faster.
+
+Note: To validate the changes followed below procedure
+1) Setup 5100 distributed volumes 3x1
+2) Enable brick_mux
+3) Start all the volumes
+4) Kill all gluster processes on 3rd node
+5) Run a loop to update volume option on a 1st node
+   for i in {1..5100}; do gluster v set vol$i performance.open-behind off; done
+6) Start the glusterd process on the 3rd node
+7) Wait to finish handshake and check there should not be any call_bail message
+   in the logs

+Subject: [PATCH 512/517] glusterd: shared storage mount fails in ipv6
+ environment
+
+Issue:
+In case of ipv6 environment, the mounting of glusterd_shared_storage
+volume fails as it doesn't recognises the ipv6 enviornment.
+
+Fix:
+In case of ipv6 environment, the address-family is passed
+to the hooks script on creating shared-storage, then depending
+upon the address-family --xlator-option=transport.address-family=inet6
+option is added to the mount command, and the mounting succeeds.

+Subject: [PATCH 513/517] afr: mark pending xattrs as a part of metadata heal
+
+...if pending xattrs are zero for all children.
+
+Problem:
+If there are no pending xattrs and a metadata heal needs to be
+performed, it can be possible that we end up with xattrs inadvertendly
+deleted from all bricks, as explained in the  BZ.
+
+Fix:
+After picking one among the sources as the good copy, mark pending xattrs on
+all sources to blame the sinks. Now even if this metadata heal fails midway,
+a subsequent heal will still choose one of the valid sources that it
+picked previously.

+Subject: [PATCH 514/517] afr: event gen changes
+
+The general idea of the changes is to prevent resetting event generation
+to zero in the inode ctx, since event gen is something that should
+follow 'causal order'.
+
+Change #1:
+For a read txn, in inode refresh cbk, if event_generation is
+found zero, we are failing the read fop. This is not needed
+because change in event gen is only a marker for the next inode refresh to
+happen and should not be taken into account by the current read txn.
+
+Change #2:
+The event gen being zero above can happen if there is a racing lookup,
+which resets even get (in afr_lookup_done) if there are non zero afr
+xattrs. The resetting is done only to trigger an inode refresh and a
+possible client side heal on the next lookup. That can be acheived by
+setting the need_refresh flag in the inode ctx. So replaced all
+occurences of resetting even gen to zero with a call to
+afr_inode_need_refresh_set().
+
+Change #3:
+In both lookup and discover path, we are doing an inode refresh which is
+not required since all 3 essentially do the same thing- update the inode
+ctx with the good/bad copies from the brick replies. Inode refresh also
+triggers background heals, but I think it is okay to do it when we call
+refresh during the read and write txns and not in the lookup path.
+
+The .ts which relied on inode refresh in lookup path to trigger heals are
+now changed to do read txn so that inode refresh and the heal happens.

+Subject: [PATCH 515/517] cluster/afr: Heal directory rename without
+ rmdir/mkdir
+
+Problem1:
+When a directory is renamed while a brick
+is down entry-heal always did an rm -rf on that directory on
+the sink on old location and did mkdir and created the directory
+hierarchy again in the new location. This is inefficient.
+
+Problem2:
+Renamedir heal order may lead to a scenario where directory in
+the new location could be created before deleting it from old
+location leading to 2 directories with same gfid in posix.
+
+Fix:
+As part of heal, if oldlocation is healed first and is not present in
+source-brick always rename it into a hidden directory inside the
+sink-brick so that when heal is triggered in new-location shd can
+rename it from this hidden directory to the new-location.
+
+If new-location heal is triggered first and it detects that the
+directory already exists in the brick, then it should skip healing the
+directory until it appears in the hidden directory.

+Subject: [PATCH 516/517] afr: return -EIO for gfid split-brains.
+
+Problem:
+entry-self-heal-anon-dir-off.t was failing occasionally because
+afr_gfid_split_brain_source() returned -1 instead of -EIO for
+split-brains, causing the code to proceed to afr_lookup_done(), which
+in turn succeeded the lookup if there was a parallel client side heal
+going on.
+
+Fix:
+Return -EIO instead of -1 so that lookp fails.
+
+Also, afr_selfheal_name() was using the same dict to get and set values. This
+could be problematic if the caller passed local->xdata_req, since
+setting a response in a request dict can lead to bugs.So changed it to use
+separate request and response dicts.
+

+Subject: [PATCH 517/517] gfapi: 'glfs_h_creat_open' - new API to create handle
+ and open fd
+
+Right now we have two separate APIs, one
+- 'glfs_h_creat_handle' to create handle & another
+- 'glfs_h_open' to create a glfd to return to application
+
+Having two separate routines can result in access errors
+while trying to create and write into a read-only file.
+
+Since a fd is opened even during file/directory creation,
+introducing a new API to make these two operations atomic i.e,
+which can create both handle & fd and pass them to application
+
+This is backport of below mainline patch -

+
+Open behind was not keeping any reference on fd's pending to be
+opened. This makes it possible that a concurrent close and en entry
+fop (unlink, rename, ...) caused destruction of the fd while it
+was still being used.

+From b924c8ca8a133fc9413c8ed1407e63f1658c7e79 Mon Sep 17 00:00:00 2001
+From: Xavi Hernandez <xhernandez@redhat.com>
+Date: Tue, 12 May 2020 23:54:54 +0200
+Subject: [PATCH 523/526] open-behind: rewrite of internal logic
+
+There was a critical flaw in the previous implementation of open-behind.
+
+When an open is done in the background, it's necessary to take a
+reference on the fd_t object because once we "fake" the open answer,
+the fd could be destroyed. However as long as there's a reference,
+the release function won't be called. So, if the application closes
+the file descriptor without having actually opened it, there will
+always remain at least 1 reference, causing a leak.
+
+To avoid this problem, the previous implementation didn't take a
+reference on the fd_t, so there were races where the fd could be
+destroyed while it was still in use.
+
+To fix this, I've implemented a new xlator cbk that gets called from
+fuse when the application closes a file descriptor.
+
+The whole logic of handling background opens have been simplified and
+it's more efficient now. Only if the fop needs to be delayed until an
+open completes, a stub is created. Otherwise no memory allocations are
+needed.
+
+Correctly handling the close request while the open is still pending
+has added a bit of complexity, but overall normal operation is simpler.

++/* Note: The initial design of open-behind was made to cover the simple case
++ *       of open, read, close for small files. This pattern combined with
++ *       quick-read can do the whole operation without a single request to the
++ *       bricks (except the initial lookup).
++ *
++ *       The way to do this has been improved, but the logic remains the same.
++ *       Basically, this means that any operation sent to the fd or the inode
++ *       that it's not a read, causes the open request to be sent to the
++ *       bricks, and all future operations will be executed synchronously,
++ *       including opens (it's reset once all fd's are closed).

+Date: Wed, 19 Aug 2020 23:27:38 +0200
+Subject: [PATCH 524/526] open-behind: fix call_frame leak
+
+When an open was delayed, a copy of the frame was created because the
+current frame was used to unwind the "fake" open. When the open was
+actually sent, the frame was correctly destroyed. However if the file
+was closed before needing to send the open, the frame was not destroyed.
+
+This patch correctly destroys the frame in all cases.

+Subject: [PATCH 525/526] open-behind: implement create fop
+
+Open behind didn't implement create fop. This caused that files created
+were not accounted for the number of open fd's. This could cause future
+opens to be delayed when they shouldn't.
+
+This patch implements the create fop. It also fixes a problem when
+destroying the stack: when frame->local was not NULL, STACK_DESTROY()
+tried to mem_put() it, which is not correct.

+Subject: [PATCH 527/532] Events: Socket creation after getaddrinfo and IPv4
+ and IPv6 packet capture
+
+Issue: Currently, the socket creation is done
+prior to getaddrinfo function being invoked. This
+can cause mismatch in the protocol and address
+families of the created socket and the result
+of the getaddrinfo api. Also, the glustereventsd
+UDP server by default only captures IPv4 packets
+hence IPv6 packets are not even captured.
+
+Code Changes:
+1. Modified the socket creation in such a way that
+the parameters taken in are dependent upon the
+result of the getaddrinfo function.
+2. Created a subclass for adding address family
+in glustereventsd.py for both AF_INET and AF_INET6.
+3. Modified addresses in the eventsapiconf.py.in
+
+Reasoning behind the approach:
+1. If we are using getaddrinfo function then
+socket creation should happen only after we
+check if we received back valid addresses.
+Hence socket creation should come after the call
+to getaddrinfo
+2. The listening server which pushes the events
+to the webhook has to listen for both IPv4
+and IPv6 messages as we would not be sure as to
+what address family is picked in _gf_event.

+Subject: [PATCH 529/532] geo-rep: prompt should work for ignore_deletes
+
+The python cli is intelligent enough to parse both "-" and "_" alike:
+
+Example:
+geo-replication config updated successfully
+sync_job 4
+geo-replication config updated successfully
+gluster volume geo-replication primary 127.0.0.1::secondary config | grep sync_jobs
+sync_jobs:5
+
+Thus the prompt which appears after ignore-deletes true should
+work for both ignore-deletes and ignore_deletes.

+Fix: Changing the default port to be bound by chanding it to something

+Subject: [PATCH 532/532] glusterd: fix for starting brick on new port
+
+The Errno set by the runner code was not correct when the bind() fails
+to assign an already occupied port in the __socket_server_bind().
+
+Fix:
+Updated the code to return the correct errno from the
+__socket_server_bind() if the bind() fails due to EADDRINUSE error. And,
+use the returned errno from runner_run() to retry allocating a new port
+to the brick process.

+
+Rebalance cli is not showing correct status after reboot.
+
+The CLI is not correct status because defrag object is not
+valid at the time of creating a rpc connection to show the status.
+The defrag object is not valid because at the time of start a glusterd
+glusterd_restart_rebalance can be call almost at the same time by two
+different synctask and glusterd got a disconnect on rpc object and it
+cleanup the defrag object.
+
+Solution: To avoid the defrag object populate a reference count before
+          create a defrag rpc object.

+Subject: [PATCH 536/538] dht: Ongoing IO is failed during volume shrink
+ operation (#2188)
+
+In the commit (c878174) we have introduced a check
+to avoid stale layout issue.To avoid a stale layout
+issue dht has set a key along with layout at the time
+of wind a create fop and posix validates the parent
+layout based on the key value. If layout does not match
+it throw and error.In case of volume shrink layout has
+been changed by reabalance daemon and if layout does not
+matches dht is not able to wind a create fop successfully.
+
+Solution: To avoid the issue populate a key only while
+          dht has wind a fop first time. After got an
+          error in 2nd attempt dht takes a lock and then
+          reattempt to wind a fop again.

+Subject: [PATCH 537/538] cluster/afr: Fix race in lockinfo (f)getxattr
+
+A shared dictionary was updated outside the lock after having updated
+the number of remaining answers. This means that one thread may be
+processing the last answer and unwinding the request before another
+thread completes updating the dict.
+
+    Thread 1                           Thread 2

+    LOCK()
+    call_cnt-- (=1)

+                                       }
+    update_dict(dict)
+    if (call_cnt == 0) {
+        STACK_UNWIND(dict);
+    }
+
+The updates from thread 1 are lost.
+
+This patch also reduces the work done inside the locked region and
+reduces code duplication.

+Subject: [PATCH 539/539] extras: disable lookup-optimize in virt and block
+ groups
+
+lookup-optimize doesn't provide any benefit for virtualized
+environments and gluster-block workloads, but it's known to cause
+corruption in some cases when sharding is also enabled and the volume
+is expanded or shrunk.
+
+For this reason, we disable lookup-optimize by default on those
+environments.

+Subject: [PATCH 540/540] extras: Disable write-behind for group samba.
+
+when write-behind is enabled with Samba it could be a
+source of data corruption. The translator, while
+processing a write call, immediately returns success but continues
+writing the data to the server in the background. This can cause data
+corruption when two clients relying on Samba to provide data consistency
+are operating on the same file.

+Subject: [PATCH 541/542] glusterd-volgen: Add functionality to accept any
+ custom xlator
+
+Add new function which allow users to insert any custom xlators.
+It makes to provide a way to add any processing into file operations.
+
+Users can deploy the plugin(xlator shared object) and integrate it to glusterfsd.
+
+If users want to enable a custom xlator, do the follows:
+
+1. put xlator object(.so file) into "XLATOR_DIR/user/"
+2. set the option user.xlator.<xlator> to the existing xlator-name to specify of the position in graph
+3. restart gluster volume
+
+Options for custom xlator are able to set in "user.xlator.<xlator>.<optkey>".

+Subject: [PATCH 543/543] glusterd: handle custom xlator failure cases
+
+Problem-1:
+custom xlator insertion was failing for those xlators in the brick graph
+whose dbg_key was NULL in the server_graph_table. Looking at the git log,
+the dbg_key was added in commit d1397dbd7d6cdbd2d81d5d36d608b6175d449db4
+for inserting debug xlators.
+
+Fix: I think it is fine to define it for all brick xlators below server.
+
+Problem-2:
+In the commit-op phase, glusterd_op_set_volume() updates the volinfo
+dict with the key-value pairs and then proceeds to create the volfiles.
+If any of the steps fail, the volinfo dict retains those key-values,
+until glusterd is restarted or `gluster vol reset $VOLNAME` is issued.
+
+Fix:
+Make a copy of the volinfo dict and if there are any failures in
+proceeding with the set volume logic, restore the dict to its original
+state.

+%description
+GlusterFS is a distributed file-system capable of scaling to several
+petabytes. It aggregates various storage bricks over Infiniband RDMA
+or TCP/IP interconnect into one large parallel network file
+system. GlusterFS is one of the most sophisticated file systems in
+terms of features and extensibility.  It borrows a powerful concept
+called Translators from GNU Hurd kernel. Much of the code in GlusterFS
+is in user space and easily manageable.
+
+This package includes the glusterfs binary, the glusterfsd daemon and the
+libglusterfs and glusterfs translator modules common to both GlusterFS server
+and client framework.
