Subject: [PATCH 02/12] mdadm: Fix double free
If there was a size mismatch after creation it would get fixed on grow
in imsm_fix_size_mismatch(), but due to double free "double free or corruption (fasttop)"
error occurs and grow cannot proceed.

Subject: [PATCH 04/12] udev: adapt rules to systemd v247
New events have been added in kernel 4.14 ("bind" and "unbind").
Systemd maintainer suggests to modify "add|change" branches.
This patches implements their suggestions. There is no issue yet because
new event types are not used in md.
Please see systemd announcement for details[1].

Subject: [PATCH 05/12] Replace error prone signal() with sigaction()
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 11/12] 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 13/52] 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'.

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 20/52] 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 22/52] 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

```
And mdadm later operations will trigger kernel output error message:

```

Subject: [PATCH 24/52] imsm: use same slot across container
Autolayout relies on drives order on super->disks list, but
it is not quaranted by readdir() in sysfs_read(). As a result
drive could be put in different slot in second volume.
Make it consistent by reffering to first volume, if exists.
Use enum imsm_status to unify error handling.

Subject: [PATCH 25/52] 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.

Subject: [PATCH 29/52] Monitor: use devname as char array instead of pointer
Device name wasn't filled properly due to incorrect use of strcpy.
Strcpy was used twice. Firstly to fill devname with "/dev/md/"
and then to add chosen name. First strcpy result was overwritten by
second one (as a result <device_name> instead of "/dev/md/<device_name>"
was assigned). This commit changes this implementation to use snprintf
and devname with fixed size.

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.

A relatively recent patch added a call to validate_geometry() in

This causes some ddf tests to segfault which aborts the test suite.
To fix this, avoid dereferencing chunk when the level is
LEVEL_CONTAINER or LEVEL_NONE.

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 36/52] 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

Subject: [PATCH 37/52] 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.
Fixes: 60815698c0ac ("Refactor parse_num and use it to parse optarg.")

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
line contains the keyword always.

Subject: [PATCH 44/52] 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:

From 239b3cc0b5da87e966746533b1873c439db54b16 Mon Sep 17 00:00:00 2001
From: Mateusz Grzonka <mateusz.grzonka@intel.com>
Date: Fri, 12 Aug 2022 16:36:02 +0200
Subject: [PATCH 45/52] 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.

Subject: [PATCH 46/52] tests/00readonly: Run udevadm settle before setting ro
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 50/52] 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..

# We process add events on block devices (since they are ready as soon as
# they are added to the system), but we must process change events as well
# on any dm devices (like LUKS partitions or LVM logical volumes) and on
# md devices because both of these first get added, then get brought live
# and trigger a change event. The reason we don't process change events
# on bare hard disks is because if you stop all arrays on a disk, then
# run fdisk on the disk to change the partitions, when fdisk exits it
# triggers a change event, and we want to wait until all the fdisks on
# all member disks are done before we do anything. Unfortunately, we have
# no way of knowing that, so we just have to let those arrays be brought
# up manually after fdisk has been run on all of the disks.
# First, process all add events (md and dm devices will not really do
# anything here, just regular disks, and this also won't get any imsm
# array members either)
