This is a memory leak.
In drbd_state_err() function, if resource->state_change_err_str is a null pointer,
the err_str will not be free.
And _drbd_state_err() has same issues.
So, if err_str has not put to up layer, free it in current function.

Subject: [PATCH 02/20] drbd: improve decision about marking a failed disk
Outdated
Sometimes it is possible to update the metadata even after our disk has
failed. We were too eager to remove the MDF_WAS_UP_TO_DATE flag in this
case.
Firstly, we used the "NOW" states, so would mark our metadata Outdated
if we were a Primary with UpToDate data and no peers, and our disk
failed. Use the "NEW" states instead.
Secondly, do not consider peers that are disconnecting, because they
will not see that our disk state is Failed, and so will outdate
themselves. We do not want to outdate both nodes in this situation.

Subject: [PATCH 04/20] drbd: build: fix spurious re-build attempt of
compat.patch
Patching changed the timestamp of the patched files,
which are pre-requisites for generating the patch.
The second build after extracting the tarball
would try to regenerate the patch file.
Exclude generated *.mod.c from "to-be-patched" files for spatch.
Reset timestamp of patched files to that of the patch file, instead of current time.

See also upstream Linux kernel commit
0718afd47f70 ("block: introduce holder ops")
Original message:
Add a new blk_holder_ops structure, which is passed to blkdev_get_by_* and
installed in the block_device for exclusive claims. It will be used to
allow the block layer to call back into the user of the block device for
thing like notification of a removed device or a device resize.

Subject: [PATCH 09/20] drbd: reduce "net_ee not empty" info to a dynamic debug
print
This situation is known and harmless. No need to print a worrying
"killed N entries" message when it occurs.
A similar comment explaining that this is harmless was introduced in
commit:
31e0f1250f17 on disconnect, just give up all references on pages from net_ee
But the comment got lost in some refactoring:
0b220db6109e drbd: move {active,read,sync,done}_ee lists from device to connection
Bring the comment back, slightly simplified.

Subject: [PATCH 10/20] drbd: do not send P_CURRENT_UUID to DRBD 8 peer when
our disk fails
DRBD 8 does not understand P_CURRENT_UUID. Skip the peer in
diskfull_peers_need_new_cur_uuid() to avoid sending such a packet.
This is valid because the DRBD 8 peer generates a new UUID itself when
our disk fails.
This prevents failures of the form:
drbd res: Unexpected data packet Unknown (0x0044)
drbd res: peer( Primary -> Unknown ) conn( Connected -> ProtocolError ) pdsk( Failed -> DUnknown )

->open is only called on the whole device. Make that explicit by
passing a gendisk instead of the block_device.

Subject: [PATCH 12/20] drbd: Restore DATA_CORKED and CONTROL_CORKED bits
They were removed with 9072e1d1b6b3 in January 2022.
Since then, the CONTROL_CORKED mapped onto C_UNREGISTERED.
I think that had a negligible impact because C_UNREGISTERED indicates
if a connection was deleted before. It is no longer connected when it
is time to delete a connection. Therefore, the corking code can not
set that double-used bit.
The other user of C_UNREGISTERED is when iterating over connections. A
wrongly set C_UNREGISTERED causes another iteration over the
connections list - no further harm.
Still, I am fixing this by allocating dedicated bits for corking in
the flags word.

Subject: [PATCH 15/20] compat: block: use the holder as indication for
exclusive opens
See also upstream Linux kernel commit
2736e8eeb0cc ("block: use the holder as indication for exclusive opens")
Original message:
The current interface for exclusive opens is rather confusing as it
requires both the FMODE_EXCL flag and a holder. Remove the need to pass
FMODE_EXCL and just key off the exclusive open off a non-NULL holder.
For blkdev_put this requires adding the holder argument, which provides
better debug checking that only the holder actually releases the hold,
but at the same time allows removing the now superfluous mode argument.

Subject: [PATCH 16/20] drbd: Fix `net-options --set-defaults` to not clear the
transport
So far, `drbdsetup net-options --set-defaults` cleared the
transport_name. That is a stupid bug that caused `drbdadm adjust` to
do a disconnect/connect cycle. This affected `lb-tcp` and `rdma`. As
`tcp` is the default, it was not affected by this.

Subject: [PATCH 17/20] drbd: propagate exposed UUIDs only into established
connections
Sending into connections in C_CONNECTING state while we exchange the
feature and auth packets might interfere with exchanging those. I also
witnessed that it might block unexpectedly long (2 - 6 seconds),
holding the `connection->mutex[DATA_STREAM]` mutex and again causing
troubles with establishing connections.
This is a fix for commit 772e5b21d from April 2023
"drbd: Consider outdating a disk when more recent data is behind a diskless"
Released with of 9.1.15 and 9.2.4.

Subject: [PATCH 18/20] drbd: rework autopromote
With upstream commit ae220766d87c we lost the ability to keep separate
counts for RW and RO openers. Instead, we keep track of openers using a
single count, and a flag indicating if the device was opened RW once.
Once a device was opened RW, it will stay "writable" for DRBD, until all
openers are gone. This should offer a good compromise between keeping
the old auto-promote behaviour, and the changed device interface.

Subject: [PATCH] compat: block: replace fmode_t with a block-specific type for
block open flags
See also upstream Linux kernel commit
05bdb9965305 ("block: replace fmode_t with a block-specific type for block open flags"
Original message:
The only overlap between the block open flags mapped into the fmode_t and
other uses of fmode_t are FMODE_READ and FMODE_WRITE. Define a new
blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and
->ioctl and stop abusing fmode_t.

Subject: [PATCH] compat: genetlink: remove userhdr from struct genl_info
See also upstream Linux kernel commit
bffcc6882a1b ("genetlink: remove userhdr from struct genl_info")
Original message:
Only three families use info->userhdr today and going forward
we discourage using fixed headers in new families.
So having the pointer to user header in struct genl_info
is an overkill. Compute the header pointer at runtime.

Subject: [PATCH 3/3] compat: gate blkdev_* patches behind bdev_open_by_path
If we have bdev_open_by_path, there is no need to consider these patches
since they only apply to the (older) blkdev_{get_put}_* functions.

- Update DRBD version from 9.1.22 to 9.1.23 (boo#1234849)
* Changelog from Linbit:
9.1.23 (api:genl2/proto:86-101,118-121/transport:18)
--------
* Fix a corner case that can happen when DRBD establishes multiple
connections in parallel, which could lead one connection to end up in
an inconsistent replication state of WFBitMapT/Established
* Fix a corner case in which a reconciliation resync ends up in
WFBitMapT/Established
* Restrict protocol compatibility to the most recent 8.4 and 9.0 releases
* Fix a corner case causing a module ref leak on drbd_transport_tcp;
if it hits, you can not rmmod it
* rate-limit resync progress while resync is paused
* resync-target inherits history UUIDs when resync finishes,
this can prevent unexpected "unrelared data" events later
* Updated compatibility code for Linux 6.11 and 6.12
* remove patches which already included in the new version:

- Update DRBD version from 9.1.16 to 9.1.22
* Changelog from Linbit:
9.1.22 (api:genl2/proto:86-121/transport:18)
--------
* Upgrade from partial resync to a full resync if necessary when the
user manually resolves a split-brain situation
* Fix a potential NULL deref when a disk fails while doing a
forget-peer operation.
* Fix a rcu_read_lock()/rcu_read_unlock() imbalance
* Restart the open() syscall when a process auto promoting a drbd device gets
interrupted by a signal
* Remove a deadlock that caused DRBD to connect sometimes
exceptionally slow
* Make detach operations interruptible
* Added dev_is_open to events2 status information
* Improve log readability for 2PC state changes and drbd-threads
* Updated compability code for Linux 6.9
9.1.21 (api:genl2/proto:86-121/transport:18)
--------
* fix a deadlock that can trigger when deleting a connection and
another connection going down in parallel. This is a regression of
9.1.20
* Fix an out-of-bounds access when scanning the bitmap. It leads to a
crash when the bitmap ends on a page boundary, and this is also a
regression in 9.1.20.
9.1.20 (api:genl2/proto:86-121/transport:18)
--------
* Fix a kernel crash that is sometimes triggered when downing drbd
resources in a specific, unusual order (was triggered by the
Kubernetes CSI driver)
* Fix a rarely triggering kernel crash upon adding paths to a
connection by rehauling the path lists' locking
* Fix the continuation of an interrupted initial resync
* Fix the state engine so that an incapable primary does not outdate
indirectly reachable secondary nodes
* Fix a logic bug that caused drbd to pretend that a peer's disk is
outdated when doing a manual disconnect on a down connection; with
that cured impact on fencing and quorum.
* Fix forceful demotion of suspended devices
* Rehaul of the build system to apply compatibility patches out of
place that allows one to build for different target kernels from a
single drbd source tree
* Updated compability code for Linux 6.8
9.1.19 (api:genl2/proto:86-121/transport:18)
--------
* Fix a resync decision case where drbd wrongly decided to do a full
resync, where a partial resync was sufficient; that happened in a
specific connect order when all nodes were on the same data
generation (UUID)
* Fix the online resize code to obey cached size information about
temporal unreachable nodes
* Fix a rare corner case in which DRBD on a diskless primary node
failed to re-issue a read request to another node with a backing
disk upon connection loss on the connection where it shipped the
read request initially
* Make timeout during promotion attempts interruptible
* No longer write activity-log updates on the secondary node in a
cluster with precisely two nodes with backing disk; this is a
performance optimization
* Reduce CPU usage of acknowledgment processing
9.1.18 (api:genl2/proto:86-121/transport:18)
--------
* Fixed connecting nodes with differently sized backing disks,
specifically when the smaller node is primary, before establishing
the connections
* Fixed thawing a device that has I/O frozen after loss of quorum
when a configuration change eases its quorum requirements
* Properly fail TLS if requested (only available in drbd-9.2)
* Fixed a race condition that can cause auto-demote to trigger right
after an explicit promote
* Fixed a rare race condition that could mess up the handshake result
before it is committed to the replication state.
* Preserve "tiebreaker quorum" over a reboot of the last node (3-node
clusters only)
* Update compatibility code for Linux 6.6
9.1.17 (api:genl2/proto:86-121/transport:18)
--------
* fix a potential crash when configuring drbd to bind to a
non-existent local IP address (this is a regression of drbd-9.1.8)
* Cure a very seldom triggering race condition bug during
establishing connections; when you triggered it, you got an OOPS
hinting to list corruption
* fix a race condition regarding operations on the bitmap while
forgetting a bitmap slot and a pointless warning
* Fix handling of unexpected (on a resource in secondary role) write
requests
* Fix a corner case that can cause a process to hang when closing the
DRBD device, while a connection gets re-established
* Correctly block signal delivery during auto-demote
* Improve the reliability of establishing connections
* Do not clear the transport with `net-options --set-defaults`. This
fix avoids unexpected disconnect/connect cycles upon an `adjust`
when using the 'lb-tcp' or 'rdma' transports in drbd-9.2.
* New netlink packet to report path status to drbdsetup
* Improvements to the content and rate-limiting of many log messages
* Update compatibility code and follow Linux upstream development
until Linux 6.5
* remove patches which already included in the new version:
