Kernel patch 8b638081bd4520f63db1defc660666ec5f65bc15
introduced support to return UUID in DM_LIST_DEVICES_CMD.
Useful when asking for UUID of each device where the list
could be now returned directly with NAME && UUID for each device.
Returning UUID is done in backward-compatible way. There's one unused
32-bit word value after the event number. This patch sets the bit
DM_NAME_LIST_FLAG_HAS_UUID if UUID is present and
DM_NAME_LIST_FLAG_DOESNT_HAVE_UUID if it isn't (if none of these bits is
set, then we have an old kernel that doesn't support returning UUIDs). The
UUID is stored after this word. The 'next' value is updated to point after
the UUID, so that old version of libdevmapper will skip the UUID without
attempting to interpret it.
Existing mechanism was not able to trace root volume issue.
Simplify the functionality by using simply using activated flag
and trace the dtree in reverse order.
When generating table line for cache target line,
the estimation of added arguments was incorrectly
calculated as the evaluation order of "?" is
made after "+".
However the result was 'masked' by the

DM tree keeps track of created device while preloading a device tree.
When fail occures during such preload, it will now try to remove
all created and preloaded device. This makes it easier to maintain
stacking of device, since we do not need to check in-depth for
existance of all possible created devices during the failure.
Make it possible to tear down VDO volumes with blkdeactivate if VDO is
part of a device stack (and if VDO binary is installed). Also, support
optional -o|--vdooptions configfile=file.
When devices are created - we were not giving meaning error messages
when the failure happened on 'reload' part of creation.
With this patch we are now able to report both name and major:minor.
Enhancment is most visible with 'crypto' devices,
which are using 'secure' memory erase bit.
Udev debugging is a bit tricky, so to more easily pair cookie ID,
which is the lowest 16 bit - print cookie as hexa number.
This simplify pairing of processed cookies while the 'higher bit flags'
are changed for the same cookie.
Fix versioning for updated symbols dm_stats_create_region
and dm_stats_create_region.
Only the latest symbol should have global entry.
Since I'm not sure what is currenlty the best option for
old symbols - we added support for easy commenting of them
(so we do not lose information when the symbol appeared
for the first time.)
Note: some old already deleted symbols should have been
restored as comments.
Recent kernel version from kernel commit:
de7180ff908b2bc0342e832dbdaa9a5f1ecaa33a
started to report in cache status line new flag:
no_discard_passdown
Whenever lvm spots unknown status it reports:
Unknown feature in status:
So add reconginzing this feature flag and also report this with
'lvs -o+kernel_discards'
When no_discard_passdown is found in status 'nopassdown' gets reported
for this field (roughly matching what we report for thin-pools).
When preparing ioctl buffer and flatting all parameters,
add table parameters only to ioctl that do process them.
Note: list of ioctl should be kept in sync with kernel code.
DM_DEVICE_CREATE with table is doing several ioctl operations,
however only some of then takes parameters.
Since _create_and_load_v4() reused already existing dm task from
DM_DEVICE_RELOAD it has also kept passing its table parameters
to DM_DEVICE_RESUME ioctl - but this ioctl is supposed to not take
any argument and thus there is no wiping of passed data - and
since kernel returns buffer and shortens dmi->data_size accordingly,
anything past returned data size remained uncleared in zfree()
function.
This has problem if the user used dm_task_secure_data (i.e. cryptsetup),
as in this case binary expact secured data are erased from main memory
after use, but they may have been left in place.
This patch is also closing the possible hole for error path,
which also reuse same dm task structure for DM_DEVICE_REMOVE.
Introduce VDO plugin for monitoring VDO devices.
This plugin can be used also by other users, as plugin checks
for UUID prefix 'LVM-' and run lvm actions only on those
devices.
Non LVM- device are only monitored and log warnings
when usage threshold reaches 80%.
btrfs is using fake major:minor device numbers.
try to be smarter and detect used node via DM device name.
This shortens delays, where i.e. lvm2 is asked to deactivate
volume with mounted btrfs as such operation is not retryed
and user is informed about device being in use.
When function dm_stats_populate() returns 0 it's an error and needs
log_error() message - function can't have 'success' returning 0 or
error without reasons.
Prevent call of dm_stats_populate(), when there has been no
stats region detected for a DM device.
Such skip is evaluated as 'correct' visit of stats call and
not causing 'dmstats' command failure.
When dmeventd thin plugin forks a configurable script, switch to use
execvp to pass whole environment present to dmeventd - so all configured
paths present at dmeventd startup are visible to script.
This was likely not a problem for common user enviroment,
however in test suite case variable like LVM_SYSTEM_DIR were
not actually used from test itself but rather from
a system present lvm.conf and this may have cause strange
behavior of a testing script.
Variable props.send_messages has 3 states and was not used properly
here. Activation in this moment does not need to verify thin-pool status
as that has been already checked on preload.
So only if there are some real messages (value 2) call function
for sending them.
Replicator never really existed in upstream kernel and its support
got deprecated.
Also its support never got finished so no code is supposed to be
using it anyway.
Libdm symbols are remaining, just the implementation will always
return failure - so any user of:
dm_tree_node_add_replicator_dev_target()
dm_tree_node_add_replicator_target().
will now always recieve error message.
Separate handling of error code from _info_by_dev.
This error can only happeng when we are running out of memory.
In such case there is urgent need to stop any futher proceeding
of command and run to error ASAP.
Propagate delayed resume at least for preload case in a simple way.
Currently PVMOVE depends on internal logic where 'mirror' with
corelog is 'possible' PVMOVE. In such case resume of 'created'
node is 'delayed'.
This is mostly an ugly internal hack - but for the moment being when we
add propagation for preload - it does work reasonable.
TODO: provide standard API and avoid this internal 'guessing'.
We always preferred and recommended socket activation for our services
so remove the Install section in related .service units which are unused
in this case and keep only the Install section in associated .socket
units.

When dmeventd receives SIGTERM/INT/HUP/QUIT it validates if exit is possible.
If there was any device still monitored, such exit request used to
be ignored/refused. This 'usually' worked reasonably well, however if there
is very short time period between last device is unmonitored and signal
reception - there was possibility such EXIT was ignored, as dmeventd has
not yet got into idle state even commands like 'vgchange -an' has already
finished.
This patch changes logic towards scheduling EXIT to the nearest
point when there is no monitored device.
EXIT is never forgotten.
NOTE: if there is only a single monitored device and someone sends
SIGTERM and later someone uses i.e. 'lvchange --refresh' after
unmonitoring dmeventd will exit and new instance needs to be
started.
There's nothing special about /boot other than it's used during boot.
But when blkdeactivate is called either on all devices or including a
device where the /boot is on top, we should also include this mount
point when doing unmount before deactivation of supported devices.
The new blkdeactivate -r|mdraidoption wait causes blkdeactivate to wait
for any resync/recovery/reshape that is currently in progress before
deactivating the device.
If this option is used, blkdeactivate calls mdadm -W|--wait before
mdadm -S|--stop.

We're canonicalizing/escaping the names here and we're reusing the
variable name so the code doesn't need to use extra variables and
further assignments that may confuse us. Let's keep the code simple.
The
local name=(...$name)
is not the same as
local name
name=(...$name)
(I know various code-checking tools fuss about this and recommend
the 2nd way, but let's ignore those tools' nitpicking here please.)
There was a typo in blkdeactivate --dmoption/--lvmoption/mpathoption,
it had missing "s" at the end and it was not recognized properly, only
short names for the options (-d/-l/-m).
The following commands now pass the device list through a
--select|-S filter before processing:
suspend resume clear wipe_table remove deps status table
Add the new concise format to dmsetup create, either as a single
command-line parameter or from stdin.
Based on patches submitted by
Enric Balletbo i Serra <enric.balletbo@collabora.com>.
Create a new table output format that concisely shows multiple devices
on one line.
dmsetup table --concise [device...]
<dev_name>,<uuid>,<flags>[,<table>]*[;<dev_name>,<uuid>,<flags>[,<table>]*]*
Table lines are separated by commas.
Devices are separated by semi-colons.
Flags is currently 'ro' or 'rw' (and might be extended in a
yet-to-be-defined way in future).
Any comma, semi-colon or backslash within a field is quoted by a
preceding backslash.
The format can later be supplied as input to dmsetup or even to the
booting kernel as an alternative way to set up devices.

The blkid we call in 13-dm-disk.rules also returns identifiers for
partitions based on which the /dev/disk/by-part{uuid,label} and
gpt-auto-root symlinks should be created in the same manner as we
already create symlinks for filesystem labels and uuids.
This is because we handle blkid calls and symlink creation under
/dev/disk ourselves in our 13-dm-disk.rules for device-mapper devices
for us to have more control over this process.
See also https://lists.freedesktop.org/archives/systemd-devel/2017-July/039220.html
and original report http://tracker.ceph.com/issues/19489 for
the exact case where these symlinks were missing.
