Subject: [PATCH 127/165] imsm: move sum_extents calculations to
merge_extents()
This logic is only used by merge_extents() code, there is no need to pass
it as parameter. Move it up. Add proper description.

Subject: [PATCH 131/165] imsm: return free space after volume for expand
merge_extends() routine searches for the biggest free space. For expand,
it works only in standard cases where the last volume is expanded and
the free space is determined after the last volume.
Add volume index to extent struct and use that do determine size after
super->current_vol during expand.
Limitation to last volume is no longer needed. It unblocks scenarios
where kill-subarray is used to remove first volume and later it is
recreated (now it is the second volume, even if it is placed before
existing one).

Subject: [PATCH 132/165] imsm: fix free space calculations
Between two volumes or between last volume and metadata at least
IMSM_RESERVED_SECTORS gap must exist. Currently the gap can be doubled
because metadata reservation contains IMSM_RESERVED_SECTORS too.
Divide reserve variable into pre_reservation and post_reservation to be
more flexible and decide separately if each reservation is needed.
Pre_reservation is needed only when a volume is created and it is not a
real first volume in a container (we can check that by extent_idx).
This type of reservation is not needed for expand.
Post_reservation is not needed only if real last volume is created or
expanded because reservation is done with the metadata.
The volume index in metadata cannot be trusted, because the real volume
order can be reversed. It is safer to use extent table, it is sorted by
start position.

Subject: [PATCH 133/165] Add secure gethostname() wrapper
gethostname() func does not ensure null-terminated string
if hostname is longer than buffer length.
For security, a function s_gethostname() has been added
to ensure that "\0" is added to the end of the buffer.
Previously this had to be handled in each place
of the gethostname() call.

service can finish check
mdcheck_continue is triggered by mdcheck_start timer. It's used to
continue check action if the raid is too big and mdcheck_start
service can't finish check action. If mdcheck start can finish check
action, it doesn't need to mdcheck continue service anymore. So stop
it when mdcheck start service can finish check action.

Subject: [PATCH 141/165] imsm: Add reading vmd register for finding imsm
capability
Currently mdadm does not find imsm capability when running inside VM.
This patch adds the possibility to read from vmd register and check for
capability, effectively allowing to use mdadm with imsm inside virtual machines.
Additionally refactor find_imsm_capability() to make assignments in new
lines.

Subject: [PATCH 142/165] Add compiler defenses flags
It is essential to avoid buffer overflows and similar bugs as much as
possible.
According to Intel rules we are obligated to verify certain
compiler flags, so it will be much easier if they are added to the
Makefile.
Add gcc flags for prevention of buffer overflows, format string vulnerabilities,
stack protection to prevent stack overwrites and aslr enablement through -fPIE.
Also make the flags configurable.
The changes were verified on gcc versions 7.5, 8.3, 9.2, 10 and 12.2.

Subject: [PATCH 143/165] Assemble: fix redundant memory free
Commit e9fb93af0f76 ("Fix memory leak in file Assemble")
fixes few memory leaks in Assemble, but it introduces
problem with assembling RAID volume. It was caused by
clearing metadata too fast, not only on fail in
select_devices() function.
This commit removes redundant memory free.

Prepare to add a regression test for raid10 that require error injection
to trigger error path, and kernel will complain about io error, checking
dmesg for error log will make it impossible to pass this test.

Subject: [PATCH 153/165] tests: create 00confnames
The test is an attempt to document current implementation of devnode
and name handling for config entries. It is focused on incremental-
default way of array assembling on boot.
The expectations are aligned to current implementation for native
metadata because it is the most complicated scenario- both variables
can be set.

Subject: [PATCH 154/165] mdadm: set ident.devname if applicable
This patch tries to propagate the usage of struct mddev_ident for cmdline
where it is applicable. To avoid regression, this value is derived
from devlist->devname for applicable modes only.
As a result, the whole structure is passed to some functions. It produces
some changes for Build, Create and Assemble.
No functional changes intended.
The goal of the change is to unify devname validation which is done in
next patches.

Subject: [PATCH 155/165] mdadm: refactor ident->name handling
Create dedicated setter for name in mddev_ident and propagate it.
Following changes are made:
- move duplicated code from config.c and mdadm.c into new function.
- Add error enum in mdadm.h.
- Use MD_NAME_MAX instead of hardcoded value in mddev_ident.
- Use secure functions.
- Add more detailed verification of the name.
- make error messages reusable for cmdline and config:
- for cmdline, these are errors so use pr_err().
- for config, these are just warnings, so use pr_info().

Subject: [PATCH 156/165] mdadm: define ident_set_devname()
Use dedicated set method for ident->devname. Now, devname validation
is done early for modes where device is created (Build, Create and
Assemble). The rules, used for devname validation are derived from
config file.
It could cause regression with execeptional cases where existing device
has name which doesn't match criteria for Manage and Grow modes. It is
low risk and those modes are not omitted from early devname validation.
Use can used main numbered devnode to avoid this problem.
Messages exposed to user are changed so it might cause a regression
in negative scenarios. Error codes are not changed.

Subject: [PATCH 157/165] mdadm: Follow POSIX Portable Character Set
When the user creates a device with a name that contains whitespace,
mdadm timeouts and throws an error. This issue is caused by udev, which
truncates /dev/md link until the first whitespace.
This patch introduces prohibition of characters other than A-Za-z0-9.-_
in the device name. Also, it prohibits using leading "-" in device name,
so name won't be confused with cli parameter.
Set of allowed characters is taken from POSIX 3.280 Portable Character
Set. Also, device name length now is limited to NAME_MAX.
In some places, there are other requirements for string length (e.g. size
up to MD_NAME_MAX for device name). This routine is made to follow POSIX
and other, more strict limitations should be checked separately.
We are aware of the risk of regression in exceptional cases (as
escape_devname function is removed) that should be fixed by updating
the array name.
The POSIX validation is added for:
- 'name' parameter in every mode.
- first devlist entry, for Build, Create, Assemble, Manage, Grow.
- config entries, both devname and "name=".
Additionally, some manual cleanups are made.

From ba489abd688bf70c83e70700aaaec5f5e90889c5 Mon Sep 17 00:00:00 2001
From: Coly Li <colyli@suse.de>
Date: Mon, 14 Aug 2023 00:46:13 +0800
Subject: [PATCH 158/165] Incremental: remove obsoleted calls to udisks
Utility udisks is removed from udev upstream, calling this obsoleted
command in run_udisks() doesn't make any sense now.
This patch removes the calls chain of udisks, which includes routines
run_udisk(), force_remove(), and 2 locations where force_remove() are
called. Considering force_remove() is removed with udisks util, it is
fair to remove Manage_stop() inside force_remove() as well.
In the two modifications where calling force_remove() are removed,
the failure from Manage_subdevs() can be safely ignored, because,
1) udisks doesn't exist, no need to check the return value to umount
the file system by udisks and remove the component disk again.
2) After the 'I' inremental remove, there is another 'r' hot remove
following up. The first incremental remove is a best-try effort.
Therefore in this patch, where force_remove() is removed, the return
value of calling Manage_subdevs() is not checked too.

Subject: [PATCH 160/165] Fix race of "mdadm --add" and "mdadm --incremental"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There is a raid1 with sda and sdb. And we add sdc to this raid,
it may return -EBUSY.
The main process of --add:
1. dev_open（sdc) in Manage_add
2. store_super1(st, di->fd) in write_init_super1
3. fsync(fd) in store_super1
4. close(di->fd) in write_init_super1
5. ioctl(ADD_NEW_DISK)
Step 2 and 3 will add sdc to metadata of raid1. There will be
udev(change of sdc) event after step4. Then "/usr/sbin/mdadm
--incremental --export $devnode --offroot $env{DEVLINKS}"
will be run, and the sdc will be added to the raid1. Then
step 5 will return -EBUSY because it checks if device isn't
claimed in md_import_device()->lock_rdev()->blkdev_get_by_dev()
->blkdev_get().
It will be confusing for users because sdc is added first time.
The "incremental" will get map_lock before add sdc to raid1.
So we add map_lock before write_init_super in "mdadm --add"
to fix the race of "add" and "incremental".

Subject: [PATCH 163/165] mdadm/super1: Add MD_FEATURE_RAID0_LAYOUT if
kernel>=5.4
After and include kernel v5.4, it adds one feature bit MD_FEATURE_RAID0_LAYOUT.
It must need to specify a layout for raid0 with more than one zone. But for
raid0 with one zone, in fact it also has a defalut layout.
Now for raid0 with one zone, *unknown* layout can be seen when running mdadm -D
command. It's the reason that mdadm doesn't set MD_FEATURE_RAID0_LAYOUT for
raid0 with one zone. Then in kernel space, super_1_validate sets mddev->layout
to -1 because of no MD_FEATURE_RAID0_LAYOUT. In fact, in raid0 io path, it
uses the default layout. Set raid0_need_layout to true if kernel_version<=v5.4.
Fixes: 329dfc28debb ('Create: add support for RAID0 layouts.')

Arrays without enough disk count will be assembled but not
started.
Now RAIDs will be assembled always (even if they are failed).
RAID devices in all states will be assembled and exposed
to mdstat.
This change affects only IMSM (for ddf it wasn't used,
container_enough was set to true always).
Removed this logic from incremental_container as well with
runstop checking because runstop condition is being verified
in assemble_container_content function.

Subject: [PATCH 165/165] Fix assembling RAID volume by using incremental
After change "mdadm: remove container_enough logic"
IMSM volumes are started immediately. If volume is during
reshape, then it will be blocked by block_subarray() during
first mdadm -I <devname>. Assemble_container_content() for
next disk will see the change because metadata version from
sysfs and metadata doesn't match and will execute
sysfs_set_array again. Then it fails to set same
component_size, it is prohibited by kernel.
If array is frozen then first sign from metadata version
is different ("/" vs "-"), so exclude it from comparison.
All we want is to double check that base properties are set
and we don't need to call sysfs_set_array again.
