Subject: [PATCH] cgroup: Also set io.bfq.weight
Current kernels with BFQ scheduler do not yet set their IO weight
through "io.weight" but through "io.bfq.weight" (using a slightly
different interface supporting only default weights, not per-device
weights). This commit enables "IOWeight=" to just to that.
This patch may be dropped at some time later.

Subject: [PATCH] meson: remove strange dep that causes meson to enter infinite
loop
The value is obviously bogus, but didn't seem to cause problems so far.
With meson-0.52.0, it causes a hang. The number of aliases is always rather
small (usually just one or two, possibly up to a dozen in a few cases), so
even if this causes some looping, it is strange that it has such a huge impact.
But let's just remove it.
Fixes #13742.
Tested with meson-0.52.0-1.module_f31+6771+f5d842eb.noarch,
meson-0.51.1-1.fc29.noarch.

copy_bytes() if people ask us to.

Subject: [PATCH] initrd: extend SYSTEMD_IN_INITRD to accept non-ramfs rootfs
Sometimes, non-ramfs initrd root are useful. Eg, for kdump, because
initramfs is memory consuming, so mount a compressed image in earlier
initrd, chroot into it then let systemd do the rest of job is a good
solution.
But systemd doesn't recognize the initrd environment if rootfs is not a
temporary fs. This is a reasonable check, because switch-root in initrd
will wipe the whole rootfs, will be a disaster if there are any
misdetect.
So extend SYSTEMD_IN_INITRD environment variable, now it accepts boolean
value and two extra keyword, "auto" and "lenient". "auto" is same as
before, and it's the default value. "lenient" will let systemd bypass
the rootfs check.

Subject: [PATCH] units: order user-runtime-dir@.service after
systemd-user-sessions.service
We use systemd-user-sessions.service as barrier when to allow login
sessions. With this patch user@.service is ordered after that too, so
that any login related code (which user-runtime-dir@.service is) is
guaranteed to run after the barrier, and never before.

Subject: [PATCH] user-runtime-dir: downgrade a few log messages to LOG_DEBUG
that we ignore
As the comments already say it might be quite likely that
$XDG_RUNTIME_DIR is not set up as mount, and we shouldn't complain about
that.
Moreover, let's make this idempotent, so that a runtime dir that is
already gone and is removed again doesn't cause failure.

Since switching to extract_first_word with no flags for parsing
unit names in 4c9565eea534cd233a913c8c21f7920dba229743, escape
characters will be stripped from escaped unit names such as
"mnt-persistent\x2dvolume.mount" resulting in the unit not being
configured as defined. Preserve escape characters again for
compatibility with existing preset definitions.

Subject: [PATCH] basic/cap-list: parse/print numerical capabilities
We would refuse to print capabilities which were didn't have a name
for. The kernel adds new capabilities from time to time, most recently
cap_bpf. 'systmectl show -p CapabilityBoundingSet ...' would fail with
"Failed to parse bus message: Invalid argument" because
capability_set_to_string_alloc() would fail with -EINVAL. So let's
print such capabilities in hexadecimal:
CapabilityBoundingSet=cap_chown cap_dac_override cap_dac_read_search
cap_fowner cap_fsetid cap_kill cap_setgid cap_setuid cap_setpcap

Subject: [PATCH] shared/mount-util: convert to libmount
It seems better to use just a single parsing algorithm for /proc/self/mountinfo.
Also, unify the naming of variables in all places that use mnt_table_next_fs().
It makes it easier to compare the different call sites.

Subject: [PATCH] mount-util: bind_remount: avoid calling statvfs
The commit
"util: Do not clear parent mount flags when setting up namespaces"
introduced a statvfs call read the flags of the original mount
and have them applied to the bind mount.
This has two problems:
(1) The mount flags returned by statvfs(2) do not match the flags
accepted by mount(2). For example, the value 4096 means ST_RELATIME
when returned by statvfs(2), but means MS_BIND when passed to mount(2).
(2) A call to statvfs blocks indefinitely when ran against a disconnected
network drive ( https://github.com/systemd/systemd/issues/12667 ).
We already use libmount to parse `/proc/self/mountinfo` but did not use the
mount flag information from there. This patch changes that to use the mount
flags parsed by libmount instead of calling statvfs. Only if getting the
flags through libmount fails we call statvfs.
Fixes https://github.com/systemd/systemd/issues/12667

systemd creates the symlinks anyway. That is just user-unfriendly.

Subject: [PATCH] sysctl: set kernel.core_pipe_limit=16
We need to make sure that our coredump pattern handler manages to read
process metadata from /proc/$PID/ before the kernel reaps the crashed
process. By default the kernel will reap the process as soon as it can.
By setting kernel.core_pipe_limit to a non-zero the kernel will wait for
userspace to finish before reaping.
We'll set the value to 16, which allows 16 crashes to be
processed in parallel. This matches the MaxConnections= setting in
systemd-coredump.socket.
See: #17301
(This doesn't close 17301, since we probably should also gracefully
handle if /proc/$PID/ vanished already while our coredump handler runs,
just in case people loclly set the sysctl back to zero. i.e. we should
collect what we can and rather issue an incomplete log record than
none.)

Subject: [PATCH] core: don't drop timer expired but not yet processed when
system date is changed
There is difference between time set by the user and real elapsed time because of accuracy feature.
If you change the system date(or time) between these times, the timer drops.
You can easily reproduce it with the following command.
-----------------------------------------------------------
$ systemd-run --on-active=3s ls; sleep 3; date -s "`date`"
-----------------------------------------------------------
In the following command, the problem is rarely reproduced. But it exists.
---------------------------------------------------------------------------------------------
$ systemd-run --on-active=3s --timer-property=AccuracySec=1us ls ; sleep 1; date -s "`date`"
---------------------------------------------------------------------------------------------
Note : Global AccuracySec value.
----------------------------------------------------------------------
$ cat /etc/systemd/system.conf
DefaultTimerAccuracySec=1min
----------------------------------------------------------------------

Subject: [PATCH] core: Detect initial timer state from serialized data
We keep a mark whether a single-shot timer was triggered in the caller's
variable initial. When such a timer elapses while we are
serializing/deserializing the inner state, we consider the timer
incorrectly as elapsed and don't trigger it later.
This patch exploits last_trigger timestamp that we already serialize,
hence we can eliminate the argument initial completely.

Subject: [PATCH] test-mountpointutil-util: do not assert in test_mnt_id()
https://bugzilla.redhat.com/show_bug.cgi?id=1803070
I *think* this a kernel bug: the mnt_id as listed in /proc/self/mountinfo is different
than the one we get from /proc/self/fdinfo/. This only matters when both statx and
name_to_handle_at are unavailable and we hit the fallback path that goes through fdinfo:

The test process does
name_to_handle_at("/proc/filesystems") which returns -EOPNOTSUPP, and then
openat(AT_FDCWD, "/proc/filesystems") which returns 4, and then
read(open("/proc/self/fdinfo/4", ...)) which gives
"pos:\t0\nflags:\t012100000\nmnt_id:\t725\n"
and the "725" is clearly inconsistent with "700" in /proc/self/mountinfo.
We could either drop the fallback path (and fail name_to_handle_at() is not
avaliable) or ignore the error in the test. Not sure what is better. I think
this issue only occurs sometimes and with older kernels, so probably continuing
with the current flaky implementation is better than ripping out the fallback.
