The device-mapper directory now holds a copy of libdm source. At
the moment this code is identical to libdm. Over time code will
migrate out to appropriate places (see doc/refactoring.txt).
The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).
All code using libdm should now use the version in device-mapper.
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/
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.

Replace lowercase @sbindir@ with @SBINDIR@ which contains
fully decoded path.
Same with @usrsbindir@ which is also used with clvmd and cmirrord.
Also handle SYSCONFDIR for EnvironmentFile.
Patch fixes generated unit files with strings like:
ExecStart=${exec_prefix}/sbin/lvm
split resize_crypt function in two.
a) Detect proper dm-crypt device type and count new --size
value for cryptsetup resize command.
b) Perform the resize
Add these for dmeventd systemd unit (dm-event.service):
Before: shutdown.target
Conflicts: shutdown.target
This will cause the dmeventd to be properly stopped at shutdown (after
all the dmeventd clients unregistered their devices from monitoring)
with dm-event.service's stop action (there's no direct action defined
for the "stop" so systemd sends SIGTERM instead).
Before, we let dmeventd to get killed only as part of the very last
SIGTERM/SIGKILL for all the remaining processes late in the shutdown
sequence so we may have missed some logs if dmeventd encountered an
error during its shutdown (logging facilities are already off at this
late time in shutdown sequence).

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.
Revert dc50f2f4a0.
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).
Drop 'DMEVENT' make variable and use BUILD_DMEVENTD like with other daemons.
NOTE: by default we do not build dmeventd - maybe time to change
as lot of build targets basically do need dmeventd...
Switch to use SYSTEMD_LIBS and avoid linking systemd library with
every linked tool when dbus notification are enabled.
(TODO add missing testing for lib presence)
Commit 1fe4f80e45 in current version
introduced regression for a terminal user, as he could not enter 'n'
as answer. Add missing break for this case (No whats_new).
When 'fsadm' was running without terminal (i.e. pipe), it's been
automatically working like in '--yes'.
Detect terminal and only accept empty "" input in this mode.
Add more validation to catch mainly renamed devices, where
filesystem utils are not able to handle devices properly,
as they are not addressed by major:minor by rather via some
symbolic path names which can change over time via rename operation.
Since we add more validation to 'detect_mounted' function make sure
we always use it even with 'resize' action, so numerous validations
are not skipped.
We have to unset the LoadState variable from previous use when we check
for systemd unit state. We use this variable to check if systemd services
are loaded or not and if it is loaded, we issue systemctl commands to
enable/disable and start/stop the service. We don't issue these commands
if the unit is not loaded to avoid error messages which may confuse users.
The blkdeactivate script processes MD devices too so we should unmount
any mount point on top of an MD device if blkdeactivate -u|--umount is
called.

If blkdeactivate finds out that the device on top of device stack
is already unmounted, it still proceeds with device stack deactivation
underneath now.
This situation can happen if blkdeactivate is started and the mount
point is unmounted in parallel by chance (so when blkdeactivate
gets the the actual umount call, the device is not mounted anymore).
Before, the blkdeactivate added such device to skip list which caused
all the stack underneath to be skipped too on deactivation. Now, we
proceed just as if blkdeactivate did the umount itself.
For example, in the example below, the vg-lvol0 is mounted on /mnt/test
when blkdeactivate is called, but it gets unmounted in parallel later
on when blkdeactivate gets to the actual umount call.
Before this patch (vg-lvol0 underneath not deactivated):
$ blkdeactivate -u
Deactivating block devices:
[UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... skipping
With this patch applied (vg-lvol0 underneath still deactivated):
$ blkdeactivate -u
Deactivating block devices:
[UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... already unmounted
[LVM]: deactivating Logical Volume vg/lvol0... done
We shouldn't be losing pvscans just because of the fact that the
underlying device (PV) appears and disappears quickly in the system,
otherwise lvmetad may not see the device if it appears again (or it may
still keep the device in cache even it's already gone).
The lsblk is just a nice helper here - it's not crucial for lvmdump so
do best effort here and use the most we can from current version of
lsblk that is installed on system. The lsblk -s option was added a bit
later after lsblk introduction and lsblk -O support even more later -
so if these are not available, use only pure lsblk output without any
extras.
Including major and minor numbers in pvs and lvs output when calling
lvmdump -a makes it a bit easier to match these items with possible
system log/journal.
blkdeactivate -m disablequeueing causes "multipathd disablequeueing maps"
call inside blkdeactivate script before deactivating devices. This
avoids a situation where blkdeactivate may wait for paths to appear if
multipath is set to queueing and there's a stack of other devices and/or
mount points on top of such multipath device.

Commit #5b3a4a9 caused the "name" variable to be cleared if
declaration and assignment is on two lines so put it back
so it's on one line for it to work again.
Don't use lvm_init() to create a full command context, which
does a lot of command setup (like connecting to daemons), which
is unnecessary for simply reading a value from lvm.conf.
Passing a NULL context arg to the lvm_config_ function is now
allowed, in which case lvm.conf is read without doing lvm
command setup.
With commit 2d5dc6512e the dbus server
no longer needs to utilize udev to know when to update its internal
state.

If we're using non-standard /dev layout so we can't get the dm-X name
easily, we can't also look at the /sys/blocl/dm-X/dev to get the major:minor
pair. Use "stat" in this case even though it triggers automounts
(but there's no better way for now).
The /proc/self/mountinfo is not bound to device names like /proc/mounts
and it uses major:minor pairs instead.
This fixes a situation in which a volume is mounted and then renamed
later on - that makes /proc/mounts unreliable when detecting mounted
volumes.
