+
+Up to this date signal() was used which implementation could vary [1].
+Sigaction() call is preferred. This commit introduces replacement
+from signal() to sigaction() by the use of signal_s() wrapper.
+Also remove redundant signal.h header includes.

+Subject: [PATCH 11/83] mdadm: add map_num_s()
+
+map_num() returns NULL if key is not defined. This patch adds
+alternative, non NULL version for cases where NULL is not expected.
+
+There are many printf() calls where map_num() is called on variable
+without NULL verification. It works, even if NULL is passed because
+gcc is able to ignore NULL argument quietly but the behavior is
+undefined. For safety reasons such usages will use map_num_s() now.
+It is a potential point of regression.

+Subject: [PATCH 13/83] mdmon: Stop parsing duplicate options
+
+Introduce new function is_duplicate_opt() to check if given option
+was already used and prevent setting it again along with an error
+message.
+
+Move parsing above in_initrd() check to be able to detect --offroot
+option duplicates.
+
+Now help option is executed after parsing to prevent executing commands
+like: 'mdmon --help --ndlksnlksajndfjksndafasj'.

+Subject: [PATCH 16/83] Mdmonitor: Fix segfault
+
+Mdadm with "--monitor" parameter requires md device
+as an argument to be monitored. If given argument is
+not a md device, error shall be returned. Previously
+it was not checked and invalid argument caused
+segmentation fault. This commit adds checking
+that devices passed to mdmonitor are md devices.

+Subject: [PATCH 18/83] Fix possible NULL ptr dereferences and memory leaks
+
+In Assemble there was a NULL check for sra variable,
+which effectively didn't stop the execution in every case.
+That might have resulted in a NULL pointer dereference.
+
+Also in super-ddf, mu variable was set to NULL for some condition,
+and then immidiately dereferenced.
+Additionally some memory wasn't freed as well.

+Subject: [PATCH 20/83] Revert "mdadm: fix coredump of mdadm --monitor -r"
+
+This reverts commit 546047688e1c64638f462147c755b58119cabdc8.
+
+The change from commit mdadm: fix coredump of mdadm
+--monitor -r broke the printing of the return message when
+passing -r to mdadm --manage, the removal of a device from
+an array.
+
+If the current code reverts this commit, both issues are
+still fixed.
+
+The original problem reported that the fix tried to address
+was:  The --monitor -r option requires a parameter,
+otherwise a null pointer will be manipulated when
+converting to integer data, and a core dump will appear.
+
+The original problem was really fixed with:
+60815698c0a Refactor parse_num and use it to parse optarg.
+Which added a check for NULL in 'optarg' before moving it
+to the 'increments' variable.
+
+New issue: When trying to remove a device using the short
+argument -r, instead of the long argument --remove, the
+output is empty. The problem started when commit
+546047688e1c was added.
+
+Steps to Reproduce:
+1. create/assemble /dev/md0 device
+2. mdadm --manage /dev/md0 -r /dev/vdxx
+
+Actual results:
+Nothing, empty output, nothing happens, the device is still
+connected to the array.
+
+The output should have stated "mdadm: hot remove failed
+for /dev/vdxx: Device or resource busy", if the device was
+still active. Or it should remove the device and print
+a message:
+
+mdadm: set /dev/vdd faulty in /dev/md0
+mdadm: hot removed /dev/vdd from /dev/md0
+
+The following commit should be reverted as it breaks
+mdadm --manage -r.

+Subject: [PATCH 22/83] mdadm/super1: restore commit 45a87c2f31335 to fix
+ clustered slot issue
+
+Commit 9d67f6496c71 ("mdadm:check the nodes when operate clustered
+array") modified assignment logic for st->nodes in write_bitmap1(),
+which introduced bitmap slot issue:
+
+load_super1 didn't set up supertype.nodes, which made spare disk only
+have one slot info. Then it triggered kernel md_bitmap_load_sb to get
+wrong bitmap slot data.
+
+For fixing this issue, there are two methods:
+
+1> revert the related code of commit 9d67f6496c71. and restore the code
+   from former commit 45a87c2f31335 ("super1: add more checks for
+   NodeNumUpdate option").
+   st->nodes value would be 0 & 1 under current code logic. i.e.
+   When adding a spare disk, there is no place to init st->nodes, and
+   the value is ZERO.
+
+2> keep 9d67f6496c71, add additional ->nodes handling in load_super1(),
+   let load_super1 to set st->nodes when bitmap is BITMAP_MAJOR_CLUSTERED.
+   Under current mdadm code logic, load_super1 will be called many
+   times, any new code in load_super1 will cost mdadm running more time.
+   And more reason is I prefer as much as possible to limit clustered
+   code spreading in every corner.
+
+So I used method <1> to fix this issue.
+
+How to trigger:
+
+dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sda
+dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdb
+dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdc
+mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sda /dev/sdb
+mdadm -a /dev/md0 /dev/sdc
+mdadm /dev/md0 --fail /dev/sda
+mdadm /dev/md0 --remove /dev/sda
+mdadm -Ss
+mdadm -A /dev/md0 /dev/sdb /dev/sdc
+
+the output of current "mdadm -X /dev/sdc":
+(there should be (by default) 4 slot info for correct output)
+```
+        Filename : /dev/sdc
+           Magic : 6d746962
+         Version : 5
+            UUID : a74642f8:a6b1fba8:58e1f8db:cfe7b082
+          Events : 29
+  Events Cleared : 0
+           State : OK
+       Chunksize : 64 MB
+          Daemon : 5s flush period
+      Write Mode : Normal
+       Sync Size : 306176 (299.00 MiB 313.52 MB)
+          Bitmap : 5 bits (chunks), 5 dirty (100.0%)
+```
+
+And mdadm later operations will trigger kernel output error message:
+(triggered by "mdadm -A /dev/md0 /dev/sdb /dev/sdc")
+```
+kernel: md0: invalid bitmap file superblock: bad magic
+kernel: md_bitmap_copy_from_slot can't get bitmap from slot 1

+Subject: [PATCH 25/83] imsm: block changing slots during creation
+
+If user specifies drives for array creation, then slot order across
+volumes is not preserved.
+Ideally, it should be checked in validate_geometry() but it is not
+possible in current implementation (order is determined later).
+Add verification in add_to_super_imsm_volume() and throw error if
+mismatch is detected.
+IMSM allows to use only same members within container.
+This is not hardware dependency but metadata limitation.
+Therefore, 09-imsm-overlap test is removed. Testing it is pointless.
+After this patch, creation in this scenario is blocked. Offset
+verification is covered in other tests.

+
+Running the test suite requires building everything, but it seems to be
+difficult to build the static version of mdadm now seeing there
+is no readily available static udev library.
+
+The test suite doesn't need the static binary so just don't build it
+with the everything or everything-test targets.
+
+Leave the mdadm.static and install-static targets in place in case
+someone still has a use case for the static binary.

+
+The test 07reshape-grow fails most of the time. But it succeeds around
+1 in 5 times. When it does succeed, it causes the tests to die because
+mdadm has segfaulted.
+
+The segfault was caused by mdadm attempting to repoen a file
+descriptor that was already closed. The backtrace of the segfault
+was:

+
+The file descriptor was closed early in Grow_continue(). The noted commit
+moved the close() call to close the fd above the fork which caused the
+parent process to return with a closed fd.
+
+This meant reshape_array() and Grow_continue() would return in the parent
+with the fd forked. The fd would eventually be passed to reopen_mddev()
+which returned an unhandled NULL from fd2devnm() which would then be
+dereferenced in devnm2devid.
+
+Fix this by moving the close() call below the fork. This appears to
+fix the 07revert-grow test. While we're at it, switch to using
+close_fd() to invalidate the file descriptor.

+Subject: [PATCH 36/83] mdadm: Fix mdadm -r remove option regression
+
+The commit noted below globally adds a parameter to the -r option but missed
+the fact that -r is used for another purpose: --remove.
+
+After that commit, a command such as:
+
+  mdadm /dev/md0 -r /dev/loop0
+
+will do nothing seeing the device parameter will be consumed as a
+argument to the -r option; thus, there will only be one device
+seen one the command line, devs_found will only be 1 and nothing will
+happen.
+
+This caused the 01r5integ and 01raid6integ tests to hang indefinitely
+as mdadm did not remove the failed device. With the device not removed,
+it would not be readded. Then the loop waiting for the array status to
+change would loop forever.
+
+This commit was recently reverted, but the legitimate fix for the
+monitor operations was still not fixed. So add specific monitor
+short ops to re-fix the --monitor -r option.
+
+Fixes: 546047688e1c ("mdadm: fix coredump of mdadm --monitor -r")
+Fixes: 190dc029b141 ("Revert "mdadm: fix coredump of mdadm --monitor -r"")

+Subject: [PATCH 37/83] mdadm: Fix optional --write-behind parameter
+
+The commit noted below changed the behaviour of --write-behind to
+require an argument. This broke the 06wrmostly test with the error:
+
+  mdadm: Invalid value for maximum outstanding write-behind writes: (null).
+         Must be between 0 and 16383.
+
+To fix this, check if optarg is NULL before parising it, as the origial
+code did.

+Add functionality to continue if a test marked as broken fails.
+
+To mark a test as broken, a file with the same name but with the suffix
+'.broken' should exist. The first line in the file will be printed with
+a KNOWN BROKEN message; the rest of the file can describe the how the
+test is broken.
+
+Also adds --skip-broken and --skip-always-broken to skip all the tests
+that have a .broken file or to skip all tests whose .broken file's first

+From daa86d6634761796ada1f535c13e47fdd3cc95eb Mon Sep 17 00:00:00 2001
+From: Logan Gunthorpe <logang@deltatee.com>
+Date: Wed, 22 Jun 2022 14:25:19 -0600
+Subject: [PATCH 44/83] tests: Add broken files for all broken tests
+
+Each broken file contains the rough frequency of brokeness as well
+as a brief explanation of what happens when it breaks. Estimates
+of failure rates are not statistically significant and can vary
+run to run.
+
+This is really just a view from my window. Tests were done on a
+small VM with the default loop devices, not real hardware. We've
+seen different kernel configurations can cause bugs to appear as well
+(ie. different block schedulers). It may also be that different race
+conditions will be seen on machines with different performance
+characteristics.
+
+These annotations were done with the kernel currently in md/md-next:

+Subject: [PATCH 45/83] mdadm: Replace obsolete usleep with nanosleep
+
+According to POSIX.1-2001, usleep is considered obsolete.
+Replace it with a wrapper that uses nanosleep, as recommended in man.
+Add handy macros for conversions between msec, usec and nsec.

+
+In some recent kernel versions, 00readonly fails with:
+
+  mdadm: failed to set readonly for /dev/md0: Device or resource busy
+  ERROR: array is not read-only!
+
+This was traced down to a race condition with udev holding a reference
+to the block device at the same time as trying to set it read only.
+
+To fix this, call udevadm settle before setting the array read only.

+Subject: [PATCH 50/83] mdadm: Don't open md device for CREATE and ASSEMBLE
+
+The mdadm command tries to open the md device for most modes, first
+thing, no matter what. When running to create or assemble an array,
+in most cases, the md device will not exist, the open call will fail
+and everything will proceed correctly.
+
+However, when running tests, a create or assembly command may be run
+shortly after stopping an array and the old md device file may still
+be around. Then, if create_on_open is set in the kernel, a new md
+device will be created when mdadm does its initial open.
+
+When mdadm gets around to creating the new device with the new_array
+parameter it issues this error:
+
+   mdadm: Fail to create md0 when using
+   /sys/module/md_mod/parameters/new_array, fallback to creation via node
+
+This is because an mddev was already created by the kernel with the
+earlier open() call and thus the new one being created will fail with
+EEXIST. The mdadm command will still successfully be created due to
+falling back to the node creation method. However, the error message
+itself will fail any test that's running it.
+
+This issue is a race condition that is very rare, but a recent change
+in the kernel caused this to happen more frequently: about 1 in 50
+times.
+
+To fix this, don't bother trying to open the md device for CREATE,
+ASSEMBLE and BUILD commands, as the file descriptor will never be used
+anyway even if it is successfully openned. The mdfd has not been used
+for these commands since:
+
+   7f91af49ad09 ("Delay creation of array devices for assemble/build/create")
+
+The checks that were done on the open device can be changed to being
+done with stat.
+
+Side note: it would be nice to disable create_on_open as well to help
+solve this, but it seems the work for this was never finished. By default,
+mdadm will create using the old node interface when a name is specified
+unless the user specifically puts names=yes in a config file, which
+doesn't seem to be common or desirable to require this..

+mdadm: Device /dev/sdb is not large enough for data described in superblock
+mdadm: no RAID superblock on /dev/sdb
+mdadm: /dev/sdb has no superblock - assembly aborted
+
+Scenario can be demonstrated as follows:
+
+mdadm: Note: this array has metadata at the start and
+    may not be suitable as a boot device.  If you plan to
+    store '/boot' on this device please ensure that

+Subject: [PATCH 61/83] Mdmonitor: Omit non-md devices
+
+Fix segfault commit [1] introduced check whether given device is
+mddevice, but it happend to terminate Mdmonitor if at least one of given
+devices didn't fulfill that condition. In result Mdmonitor service was
+no longer started on boot (with --scan option) when config contained some
+non-existent array entry.
+
+This commit introduces ommiting non-md devices so scan option can still
+be used when config is wrong and allow Mdmonitor service to run on boot.
+
+Giving a list of devices to monitor containing non-existing or
+non-md devices will result in monitoring only confirmed mddevices.

+
+Subset of options available for "--update" is not same as for "--update-subarray".
+Define maps and enum for update options and use them instead of direct comparisons.
+Add proper error message.

+Options: bitmap, ppl and name should not be updated when array is active.
+Those features are mutually exclusive and share the same data area in IMSM (danger of overwriting by kernel).
+Remove check for active subarrays from super-intel.
+Since ddf is not supported, apply it globally for all options.

+Subject: [PATCH 76/83] Change char* to enum in context->update & refactor code
+
+Storing update option in string is bad for frequent comparisons and
+error prone.
+Replace char array with enum so already existing enum is passed around
+instead of string.
+Adapt code to changes.

+Subject: [PATCH 79/83] mdadm/udev: Don't handle change event on raw devices
+
+The raw devices are ready when add event happpens and the raid
+can be assembled. So there is no need to handle change events.
+And it can cause some inconvenient problems.
+
+For example, the OS is installed on md0(/root) and md1(/home).
+md0 and md1 are created on partitions. When it wants to re-install
+OS, anaconda can't clear the storage configure. It deletes one
+partition and does some jobs. The change event happens. Now
+the raid device is assembled again. It can't delete the other
+partitions.
+
+So in this patch, we don't handle change event on raw devices
+anymore.

+Freesize is needed to be set for migrations where size of RAID could
