Subject: [PATCH 1/5] Document PART-POLICY lines
PART-POLICY has been accepted in mdadm.conf since the same
time that POLICY was accepted, but it was never documented.
So add the missing documentation.
Also fix a bug which would have stopped it from working if
anyone had ever tried to use it.

Subject: [PATCH] imsm: fix missing error message during migration
If user tries to migrate from raid0 to raid5 and there is no spare
drive to perform it - mdadm will exit with errorcode, but
no error message is printed.
Print error instead of debug message when this condition occurs,
so user is informed why requested migration is not started.

Subject: [PATCH 2/5] policy: support devices with multiple paths.
As new releases of Linux some time change the name of
a path, some distros keep "legacy" names as well. This
is useful, but confuses mdadm which assumes each device has
precisely one path.
So change this assumption: allow a disk to have several
paths, and allow any to match when looking for a policy
which matches a disk.

Subject: [PATCH] Fix oddity where mdadm did not recognise a relative path
mdadm assumed that a pathname started with a "/", while an array
name didn't. This alters the logic so that if the first character
is not a "/" it tries to open an array, and if that fails it drops
through to the pathname code rather than terminating immediately
with an error.

Having the mdcheck script is not use if is never run.
This patch adds systemd unit files so that it can easily
be run on the first Sunday of each month for 6 hours,
then on every subsequent morning until the check is
finished.
The units still need to be enabled with
systemctl enable mdcheck_start.timer
The timer will only actually be started when an array
which might need it becomes active.

Subject: [PATCH 4/5] Monitor: add system timer to run --oneshot periodically
"mdadm --monitor --oneshot" can be used to get a warning
if there are any degraded arrays. It can be helpful to get
this warning periodically while the condition persists.
This patch add a systemd service and timer which can
be enabled with
systemctl enable mdmonitor-oneshot.service
and will then provide daily warnings.

Date: Fri, 3 Mar 2017 10:57:00 +1100
Subject: [PATCH] examine: tidy up some code.
Michael Shigorin reports that the 'lcc' compiler isn't able
to deduce that 'st' must be initialized in
if (c->SparcAdjust)
st->ss->update_super(st, NULL, "sparc2.2",
just because the only times it isn't initialised, 'err' is set non-zero.
This results in a 'possibly uninitialised' warning.
While there is no bug in the code, this does suggest that maybe
the code could be made more obviously correct.
So this patch:
1/ moves the "err" variable inside the for loop, so an error in
one device doesn't stop the other devices from being processed
2/ calls 'continue' early if the device cannot be opened, so that
a level of indent can be removed, and so that it is clear that
'st' is always initialised before being used
3/ frees 'st' if an error occured in load_super or load_container.

Subject: [PATCH 5/5] imsm: update metadata correctly while raid10 double
degradation
Mdmon calls end_migration() when map state changes from normal to
degraded. It is not valid because in raid 10 double degradation case
mdmon breaks checkpointing but array is still rebuilding.
In this case mdmon has to mark map as degraded and continues marking
recovery checkpoint in metadata. Migration can be finished only if newly
failed device is a rebuilding device.
Add catching double degraded to degraded transition. Migration is
finished but map state doesn't change, array is still degraded.
Update failed_disk_num correctly. If double degradation
happens rebuild will start on the lowest slot, but this variable points
to the first failed slot. If second fail happens while rebuild this
variable shouldn't be updated until rebuild is not finished.

Subject: [PATCH] mdadm: Add Wimplicit-fallthrough=0 in Makefile
There are many errors like 'error: this statement may fall through'.
But the logic is right. So add the flag Wimplicit-fallthrough=0
to disable the error messages. The method I use is from
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

Subject: [PATCH] mdadm: Specify enough length when write to buffer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In Detail.c the buffer path in function Detail is defined as path[200],
in fact the max lenth of content which needs to write to the buffer is
287. Because the length of dname of struct dirent is 255.
During building it reports error:
error: ‘%s’ directive writing up to 255 bytes into a region of size 189
[-Werror=format-overflow=]
In function examine_super0 there is a buffer nb with length 5.
But it need to show a int type argument. The lenght of max
number of int is 10. So the buffer length should be 11.
In human_size function the length of buf is 30. During building
there is a error:
output between 20 and 47 bytes into a destination of size 30.
Change the length to 47.

truncation
In gcc7 there are some building errors like:
directive output may be truncated writing up to 31 bytes into a region of size 24
snprintf(str, MPB_SIG_LEN, %s, mpb->sig);
It just need to copy one string to target. So use strncpy to replace it.
For this line code: snprintf(str, MPB_SIG_LEN, %s, mpb->sig);
Because mpb->sig has the content of version after magic, so
it's better to use strncpy to replace snprintf too.

References: bsc#956236
If a device isn't fully initialized (e.g if it should be
handled by multipathing) it should not be considered for
md/RAID auto-assembly. Doing so can cause incorrect results
such as causing multipath to fail during startup.
There is a convention that the udev environment variable
SYSTEMD_READY be set to zero for such devices. So change
the mdadm rules to ignore devices with SYSTEMD_READY==0.

Subject: [PATCH] Retry HOT_REMOVE_DISK a few times.
References: bsc#808647
HOT_REMOVE_DISK can fail with EBUSY if there are outstanding
IO request that have not completed yet. It can sometimes
be helpful to wait a little while for these to complete.
We already do this in impose_level() when reshaping a device,
but not in Manage.c in response to an explicit --remove request.
So create hot_remove_disk() to central this code, and call it
where-ever it makes sense to wait for a HOT_REMOVE_DISK to succeed.

Subject: [PATCH] Introduce sys_hot_remove_disk()
References: bsc#974154
The new hot_remove_disk() will retry HOT_REMOVE_DISK
several times in the face of EBUSY.
However we sometimes remove a device by writing "remove" to the
"state" attributed. This should be retried as well.
So introduce sys_hot_remove_disk() to repeat this action a few times.

Subject: [PATCH] Add 'force' flag to *hot_remove_disk().
References: bsc#808647
In rare circumstances, the short period that *hot_remove_disk()
waits isn't long enough to IO to complete. This particularly happens
when a device is failing and many retries are still happening.
We don't want to increase the normal wait time for "mdadm --remove"
as that might be use just to test if a device is active or not, and a
delay would be problematic.
So allow "--force" to mean that mdadm should try extra hard for a
--remove to complete, waiting up to 5 seconds.
Note that this patch fixes a comment which claim the previous
wait time was half a second, where it was really 50msec.

Subject: [PATCH] Detail: handle non-existent arrays better.
References: bsc#966773
If you call "mdadm --detail" with a device file for an array which
doesn't exist, such as by
mknod /dev/md57 b 9 57
mdadm --detail /dev/md57
you get an unhelpful message about and inactive RAID0, and return
status is '0'. This is confusing.
So catch this possibility and print a more useful message, and
return a non-zero status.

Subject: [PATCH] Generic support for --consistency-policy and PPL
References: FATE#321941
Add a new parameter to mdadm: --consistency-policy=. It determines how
the array maintains consistency in case of unexpected shutdown. This
maps to the md sysfs attribute 'consistency_policy'. It can be used to
create a raid5 array using PPL. Add the necessary plumbing to pass this
option to metadata handlers. The write journal and bitmap
functionalities are treated as different policies, which are implicitly
selected when using --write-journal or --bitmap options.

From 2432ce9b3235f34d00ef6c28ef6b624a32b85530 Mon Sep 17 00:00:00 2001
From: Artur Paszkiewicz <artur.paszkiewicz@intel.com>
Date: Wed, 29 Mar 2017 11:54:17 +0200
Subject: [PATCH] imsm: PPL support
References: FATE#321941
Enable creating and assembling IMSM raid5 arrays with PPL. Update the
IMSM metadata format to include new fields used for PPL.
Add structures for PPL metadata. They are used also by super1 and shared
with the kernel, so put them in md_p.h.
Write the initial empty PPL header when creating an array. When
assembling an array with PPL, validate the PPL header and in case it is
not correct allow to overwrite it if --force was provided.
Write the PPL location and size for a device to the new rdev sysfs
attributes 'ppl_sector' and 'ppl_size'. Enable PPL in the kernel by
writing to 'consistency_policy' before the array is activated.

From: Artur Paszkiewicz <artur.paszkiewicz@intel.com>

Subject: [PATCH] super1: PPL support
References: FATE#321941
Enable creating and assembling raid5 arrays with PPL for 1.x metadata.
When creating, reserve enough space for PPL and store its size and
location in the superblock and set MD_FEATURE_PPL bit. Write an initial
empty header in the PPL area on each device. PPL is stored in the
metadata region reserved for internal write-intent bitmap, so don't
allow using bitmap and PPL together.
While at it, fix two endianness issues in write_empty_r5l_meta_block()
and write_init_super1().

Subject: [PATCH] Grow: support consistency policy change
References: FATE#321941
Extend the --consistency-policy parameter to work also in Grow mode.
Using it changes the currently active consistency policy in the kernel
driver and updates the metadata to make this change permanent. Currently
this supports only changing between "ppl" and "resync" policies, that is
enabling or disabling PPL at runtime.

Subject: [PATCH] Grow: Remove unnecessary optimization
Per explanation by Neil, this optimization of writing "size" to the
attribute of each device, however when reducing the size of devices,
the size change isn't permitted until the array has been shrunk, so
this will fail anyway.
This effectively reverts 65a9798b58b4e4de0157043e2b30a738c27eff43

Subject: [PATCH] imsm: use rounded size for metadata initialization
Array size is rounded to the nearest MB, however number of data stripes
and blocks per disk are calculated using size passed by the user. If
given size is not aligned, there is a mismatch. It's not possible to
assemble raid0 migrated to raid5 since raid5 arrays use number of data
stripes to calculate array size.

Subject: [PATCH] mdopen: use parameters/new_array to create arrays whenever
possible.
Git-commit: 039df36231335fabe4da1a22fa3accb160d8bc1b
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030
In a sufficiently recent kernel, an md%d array can be
created by writing to .../parameters/new_array.
If mdadm does this consistently, then another new
feature, disabling create_on_open, can be enabled.
This avoids races on shutdown.
An added benefit of using new_array (where available)
is that it allows md arrays with numbers larger than 511
(e.g. md999) to be created. The old create_on_open
mechanism doesn't support such devices since
Commit: af5628f05db6 ("md: disable probing for md devices 512 and over.")
in Linux 3.17.
After a few more mdadm releases it would be good to
have mdadm disable create_on_open automatically.

Grow_continue_command() call verify_reshape_position(), which assumes
that info->sys_name is initialised.
'info' in verify_reshape_position() is 'content' in Grow_continue_command().
In the st->ss->external != 0 branch of that function, sysfs_init() is called
to initialize content->sys_name.
In the st->ss->external == 0 branch, ->sys_name is not initialized so
verify_reshape_position() will not do the right thing.

Commit cec72c071bbe ("systemd/mdadm-last-resort: add Conflicts to .service file.")
added a 'Conflicts' directive to the mdadm-last-resort@.service file in
the hope that this would make sure the service didn't run after the device
was active, even if the timer managed to get started, which is possible in
race conditions.
This seemed to work is testing, but it isn't clear why, and it is known
to cause problems.
If systemd happens to know that the mentioned device is a dependency of a
mount point, the Conflicts can unmount that mountpoint, which is certainly
not wanted.
So remove the "Conflicts" and instead use
ConditionPathExists=!/sys/devices/virtual/block/%i/md/sync_action
The "sync_action" file exists for any array which requires last-resort
handling, and only appears when the array is activated. So it is safe
to rely on it to determine if the last-resort is really needed.

If an array contains a device which has a name that
contains something other than alphnumerics and underscores,
then some values reported by "mdadm --detail --export" will
not be valid as variable assignment of the shell.
This particularly affects dm devices.
e.g.
MD_DEVICE_dm-4_ROLE=1
MD_DEVICE_dm-4_DEV=/dev/dm-4
As it is particularly useful to be able to work with these
in a shell script, and as the precise name is not important,
change all non-alphanumerics to '_'.

It is a partial revert of commit 758b327cf5a7 ("Grow: Remove unnecessary
optimization"). For native metadata component size is set in kernel for
entire disk space. As external metadata supports multiple arrays within
one disk, the component size is set to array size. If component size is
not updated prior to array size update, the grow operation fails.

Don't allow array geometry change (size expand, disk adding) when PPL
consistency policy is enabled. Current PPL implementation doesn't work when
reshape is taking place.

"Array Size" and "Per Dev Size" are incorrect for disks with sector size
different than 512B.
Calculate "Array Size" and "Per Dev Size" based on sector size. Additionally
print "Sector Size".

IMSM doesn't allow to create arrays including drives with different
sector sizes. The initial idea was not to permit to combine drives
with different sector size in the same container. The problem is it
only worked for array creation. On array assemble there are no
calls to metadata handlers to see if drive is suitable for a container
(e.g. as a spare) and it leads to wrong configuration.
Revert the change and allow adding drives with different sector size
to the container.

Allocate migration record buffer to support maximum sector size. Disk with
non-matching sector size is not going to be included in the array, however
some preparation/cleanup actions still take place on it and they would
cause a crash. Clear migration record using sector size of the disk (not
array) as they might not match.

As there is no support in IMSM for arrays including disks with different
sector sizes, don't allow to create such configuration. Also skip the
disk with unsuitable sector size when looking for spares in the same
container.

Remove most direct ioctl calls for GET_ARRAY_INFO, except for one,
which will be addressed in the next patch.
This is the start of the effort to clean up the use of ioctl calls and
introduce a more structured API, which will use sysfs and fall back to
ioctl for backup.

From 5b13d2e1fb8abecddd4e28e67facac5d7ef2cef3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Incremental: Remove redundant call for GET_ARRAY_INFO
Git-commit: 5b13d2e1fb8abecddd4e28e67facac5d7ef2cef3
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030
The code above just called md_get_array_info() and only reached this
point if it returned an error that isn't ENODEV, so it's pointless to
check this again here.
In addition it was incorrectly retrieving ioctl data into a
mdu_bitmap_file_t instead of mdu_array_info_t.
Fixes: ("8382f19 Add new mode: --incremental")

This removes all the inline ioctl calls for GET_DISK_INFO, allowing us
to switch to sysfs in one place, and improves type checking.

Subject: [PATCH] mdadm/grow: reshape would be stuck from raid1 to raid5

References: bsc#1069165, bsc#1069167, bsc#1068030
systemctl doesn't interpret mdadm-grow-continue@.service
correctly due to the wrong argument provided in [service],
it should be corrected %I as %i. Otherwise, if the service
cannot start by systemctl and the reshap progress would be
stuck all time when grows array from raid1 to raid5.
reproduce steps:
./mdadm -CR /dev/md0 -l1 -b internal -n2 /dev/loop[0-1]
./mdadm --grow /dev/md0 -l5 -n3 -a /dev/loop2

Subject: [PATCH] sysfs: Use the presence of /sys/block/<dev>/md as indicator
of valid device
Git-commit: 67a02d520085b01a1b9e6ea59fb30e79c5649c9c
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030
Rather than calling ioctl(RAID_VERSION), use the presence of
/sys/block/<dev>/md as indicator of the device being valid and sysfs
being active for it. The ioctl could return valid data, but sysfs
not mounted, which renders sysfs_init() useless anyway.

check it.

Subject: [PATCH] super1: Clean up various style abuses
Git-commit: 46a533a90c01b0492577c61d4e65de2ac4bf220c
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030
Code is 80 characters wide, so lets try to respect that. In addition, we
should never have one-line 'if () action()' statements. Fixup various
whitespace abuse.
