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't finish check action. If mdcheck start can finish check

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.

The deadlock is described in [1], it's fixed first by [2], however,

it turns out this commit will trigger other problems[3], hence this
|

|
commit will be reverted and the deadlock is supposed to be fixed by [1].

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.

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

|
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".

|

|
||||||

Sometimes it can fail:
|
||||||
|
losetup: /var/tmp/mdtest0: failed to set up loop device: No such device or address
|
||||||
|
/dev/loop0 and /var/tmp/mdtest0 are already created before losetup.
|
||||||
|
|
||||||
|
Because losetup can create device node by itself. So remove mknod.

The metadata is corrupted when the raid_disk<0. So abort directly.

This also can avoid a building error:

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.')

Subject: [PATCH 164/165] mdadm: remove container_enough logic
|
||||||
|
|
||||||
|
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.
