Update to latest upstream and fix mdcheck service bug

Browse Source 
If mdcheck_start service can finish check action, it doesn't need to start mdcheck_continue
service. So in rhel only patch mdcheck.patch, we stop mdcheck_continue timer.

And there is a history problem. It needed KillMode=none before, so it removed
the upstream patch 52c67fcdd. Now this problem has been fixed, so we can do the
backport more easilly now. We don't need to remove the upstream patch here again.

Resolves: rhbz#2116418, rhbz#2150862, rhbz#2159584

Subject: [PATCH 012/125] mdadm/systemd: remove KillMode=none from service file
For mdadm's systemd configuration, current systemd KillMode is "none" in
following service files,
- mdadm-grow-continue@.service
- mdmon@.service
This "none" mode is strongly againsted by systemd developers (see man 5
systemd.kill for "KillMode=" section), and is considering to remove in
future systemd version.
As systemd developer explained in disuccsion, the systemd kill process
is,
1. send the signal specified by KillSignal= to the list of processes (if
any), TERM is the default
2. wait until either the target of process(es) exit or a timeout expires
3. if the timeout expires send the signal specified by FinalKillSignal=,
KILL is the default
For "control-group", all remaining processes will receive the SIGTERM
signal (by default) and if there are still processes after a period f
time, they will get the SIGKILL signal.
For "mixed", only the main process will receive the SIGTERM signal, and
if there are still processes after a period of time, all remaining
processes (including the main one) will receive the SIGKILL signal.
From the above comment, currently KillMode=control-group is a proper
kill mode. Since control-gropu is the default kill mode, the fix can be
simply removing KillMode=none line from the service file, then the
default mode will take effect.

This reverts commit 52c67fcdd6dadc4138ecad73e65599551804d445.
The functionality is marked as deprecated but we don't have alternative
solution yet. Shutdown hangs if OS is installed on external array:

Subject: [PATCH 085/125] Grow: fix can't change bitmap type from none to
clustered.
Commit a042210648ed ("disallow create or grow clustered bitmap with
writemostly set") introduced this bug. We should use 'true' logic not
'== 0' to deny setting up clustered array under WRITEMOSTLY condition.
How to trigger
```
~/mdadm # ./mdadm -Ss && ./mdadm --zero-superblock /dev/sd{a,b}
~/mdadm # ./mdadm -C /dev/md0 -l mirror -b clustered -e 1.2 -n 2 \
/dev/sda /dev/sdb --assume-clean
mdadm: array /dev/md0 started.
~/mdadm # ./mdadm --grow /dev/md0 --bitmap=none
~/mdadm # ./mdadm --grow /dev/md0 --bitmap=clustered
mdadm: /dev/md0 disks marked write-mostly are not supported with clustered bitmap

Date: Thu, 2 Feb 2023 12:27:01 +0100
Subject: [PATCH 089/125] Mdmonitor: Add helper functions
Add functions:
- is_email_event(),
- get_syslog_event_priority(),
- sprint_event_message(),
with kernel style comments containing more detailed descriptions.
Also update event syslog priorities to be consistent with man. MoveSpare event was described in man as priority info, while implemented as warning. Move event data into a struct, so that it is passed between different functions if needed.
Sort function declarations alphabetically and remove redundant alert() declaration.

Subject: [PATCH 096/125] isuper-intel.c: fix double free in load_imsm_mpb()
In load_imsm_mpb() there is potential double free issue on super->buf.
The first location to free super->buf is from get_super_block() <==
load_and_parse_mpb() <== load_imsm_mpb():
4514 if (posix_memalign(&super->migr_rec_buf, MAX_SECTOR_SIZE,
4515 MIGR_REC_BUF_SECTORS*MAX_SECTOR_SIZE) != 0) {
4516 pr_err("could not allocate migr_rec buffer\n");
4517 free(super->buf);
4518 return 2;
4519 }
If the above error condition happens, super->buf is freed and value 2
is returned to get_super_block() eventually. Then in the following code
block inside load_imsm_mpb(),
5289 error:
5290 if (!err) {
5291 s->next = *super_list;
5292 *super_list = s;
5293 } else {
5294 if (s)
5295 free_imsm(s);
5296 close_fd(&dfd);
5297 }
at line 5295 when free_imsm() is called, super->buf is freed again from
the call chain free_imsm() <== __free_imsm(), in following code block,
4651 if (super->buf) {
4652 free(super->buf);
4653 super->buf = NULL;
4654 }
This patch sets super->buf as NULL after line 4517 in load_imsm_mpb()
to avoid the potential double free().

Subject: [PATCH 100/125] Create: remove safe_mode_delay local variable
All .getinfo_super() call sets the info.safe_mode_delay variables
to a constant value, so no matter what the current state is
that function will always set it to the same value.
Create() calls .getinfo_super() multiple times while creating the array.
The value is stored in a local variable for every disk in the loop
to add disks (so the last disc call takes precedence). The local
variable is then used in the call to sysfs_set_safemode().
This can be simplified by using info.safe_mode_delay directly. The info
variable had .getinfo_super() called on it early in the function so, by the
reasoning above, it will have the same value as the local variable which
can thus be removed.
Doing this allows for factoring out code from Create() in a subsequent
patch.

Subject: [PATCH 101/125] Create: Factor out add_disks() helpers
The Create function is massive with a very large number of variables.
Reading and understanding the function is almost impossible. To help
with this, factor out the two pass loop that adds the disks to the array.
This moves about 160 lines into three new helper functions and removes
a bunch of local variables from the main Create function. The main new
helper function add_disks() does the two pass loop and calls into
add_disk_to_super() and update_metadata(). Factoring out the
latter two helpers also helps to reduce a ton of indentation.
No functional changes intended.

Subject: [PATCH 102/125] mdadm: Introduce pr_info()
Feedback was given to avoid informational pr_err() calls that print
to stderr, even though that's done all through out the code.
Using printf() directly doesn't maintain the same format (an "mdadm"
prefix on every line.
So introduce pr_info() which prints to stdout with the same format
and use it for a couple informational pr_err() calls in Create().
Future work can make this call used in more cases.

Subject: [PATCH 103/125] mdadm: Add --write-zeros option for Create
Add the --write-zeros option for Create which will send a write zeros
request to all the disks before assembling the array. After zeroing
the array, the disks will be in a known clean state and the initial
sync may be skipped.
Writing zeroes is best used when there is a hardware offload method
to zero the data. But even still, zeroing can take several minutes on
a large device. Because of this, all disks are zeroed in parallel using
their own forked process and a message is printed to the user. The main
process will proceed only after all the zeroing processes have completed
successfully.

Subject: [PATCH 106/125] Define alignof using _Alignof when using C11 or newer
WG14 N2350 made very clear that it is an UB having type definitions
within "offsetof" [1]. This patch enhances the implementation of macro
alignof_slot to use builtin "_Alignof" to avoid undefined behavior on
when using std=c11 or newer
clang 16+ has started to flag this [2]
Fixes build when using -std >= gnu11 and using clang16+
Older compilers gcc < 4.9 or clang < 8 has buggy _Alignof even though it
may support C11, exclude those compilers too

Subject: [PATCH 107/125] Use existence of /etc/initrd-release to detect
initrd.
Since v183, systemd has used the existence of /etc/initrd-release to
detect if it is running in an initrd, rather than looking at the magic
number of the root filesystem's device. It is time for mdadm to do the
same.

If 'all' is not set, then container_name must be NULL, as nothing else
can set it. So simplify the test to ignore container_name.
This makes the purpose of the code more obvious.

Subject: [PATCH 110/125] mdmon: Remove need for KillMode=none
mdmon needs to keep running during the switchroot out of (at boot) and
then back into (at shutdown) the initrd. It runs until a new mdmon
takes over.
Killmode=none is used to achieve this, with the help of --offroot which
sets argv[0][0] to '@' which systemd understands.
This is needed because mdmon is currently run in system-mdmon.slice
which conflicts with shutdown.target so without Killmode=none mdmon
would get killed early in shutdown when system.mdmon.slice is removed.
As described in systemd.service(5), this conflict with shutdown can be
resolved by explicitly requesting system.slice, which is a natural
counterpart to DefaultDependencies=no.
So add that, and also add IgnoreOnIsolate=true to avoid another possible
source of an early death. With these we no longer need KillMode=none
which the systemd developers have marked as "deprecated".

Subject: [PATCH 111/125] mdmon: Improve switchroot interactions.
We need a new mdmon@mdfoo instance to run in the root filesystem after
switch root, as /sys and /dev are removed from the initrd.
systemd will not start a new unit with the same name running while the
old unit is still active, and we want the two mdmon processes to overlap
in time to avoid any risk of deadlock, which can happen when a write is
attempted with no mdmon running.
So we need a different unit name in the initrd than in the root. Apart
from the name, everything else should be the same.
This is easily achieved using a different instance name as the
mdmon@.service unit file already supports multiple instances (for
different arrays).
So start "mdmon@mdfoo.service" from root, but
"mdmon@initrd-mdfoo.service" from the initrd. udev can tell which
circumstance is the case by looking for /etc/initrd-release.
continue_from_systemd() is enhanced so that the "initrd-" prefix can be
requested.
Teach mdmon that a container name like "initrd/foo" should be treated
just like "foo". Note that systemd passes the instance name
"initrd-foo" as "initrd/foo".
We don't need a similar mechanism at shutdown because dracut runs
"mdmon --takeover --all" when appropriate.

Subject: [PATCH 112/125] mdopen: always try create_named_array()
mdopen() will use create_named_array() to ask the kernel to create the
given md array, but only if it is given a number or name.
If it is NOT given a name and is required to choose one itself using
find_free_devnm() it does NOT use create_named_array().
On kernels with CONFIG_BLOCK_LEGACY_AUTOLOAD not set, this can result in
failure to assemble an array. This can particularly seen when the
"name" of the array begins with a host name different to the name of the
host running the command.
So add the missing call to create_named_array().

Subject: [PATCH 115/125] Create: Fix checking for container in update_metadata
The commit 8a4ce2c05386 ("Create: Factor out add_disks() helpers")
introduced a regression that caused timeouts and udev failing to create
links.
Steps to reproduce the issue were as following:
$ mdadm -CR imsm -e imsm -n4 /dev/nvme[0-3]n1
$ mdadm -CR vol -l5 -n4 /dev/nvme[0-3]n1 --assume-clean
I found the check for container was wrong because negation was missing.

Subject: [PATCH 116/125] Fix null pointer for incremental in mdadm
when we excute mdadm --assemble, udev-md-raid-assembly.rules is triggered.
Then we stop array, we found an coredump for mdadm --incremental.func
stack are as follows:
#0 enough (level=10, raid_disks=4, layout=258, clean=1,
avail=avail@entry=0x0) at util.c:555
#1 0x0000562170c26965 in Incremental (devlist=<optimized out>,
c=<optimized out>, st=0x5621729b6dc0) at Incremental.c:514
#2 0x0000562170bfb6ff in main (argc=<optimized out>,
argv=<optimized out>) at mdadm.c:1762
func enough() use array avail,avail allocate space in func count_active,
it may not alloc space, causing a coredump.We fix this coredump.

Subject: [PATCH 120/125] Remove the config files in mdcheck_start|continue
service
We set MDADM_CHECK_DURATION in the mdcheck_start|continue.service files.
And mdcheck doesn't use any configs from the config file. So we can remove
the dependencies.

Subject: [PATCH 125/125] enable RAID for SATA under VMD
Detect when a SATA controller has been mapped under Intel Alderlake RST
VMD, so that it can use the VMD controller's RAID capabilities. Create
new device type SYS_DEV_SATA_VMD and list separate controller to prevent
mixing with the NVMe SYS_DEV_VMD devices on the same VMD domain.
