Since 95f1d6bfecde60b245fae1ab0313b550201e7880 we'll subscribe to unit
signals to figure out when to disconnect the pty. But that can only work
correctly if we actually subscribe to the unit's signals. Hence,
explicitly pin (and thus subscribe to) the unit we just created not only
in --wait mode but also in --pty mode.
Or to say this differently: we need to pin the unit in the same cases as
we install the signal match. 95f1d6bfecde60b245fae1ab0313b550201e7880
forgot to do that.
This is relevant to make sure systemd-run works correctly in --user
mode, and correctly exits when the spawned service dies. To test:
systemd-run --user -t /bin/bash
And then press ^D. This will hang before this change, but exit cleanly
after it.
core: always consider clients that pinned a unit to be subscribers
If a client pins a unit, then it makes sense to also implicitly make it
a subscriber. This is useful for clients that just want to watch one
specific unit: they can pin it and receive its messages.

hostname: add 'convertible' chassis type
Add the 'convertible' type to the set of allowed chassis. This applies

tablet style.
This does not add any auto-detection, yet. It only makes 'set-chassis'
accept 'convertible' as valid input.

sd-boot: stub: check LoadOptions contains data (#5467)
With some UEFI shells LoadOptionsSize is reported being > 0
but the corresponding LoadOptions does not contain any data
(the first element has value 0).
When that happens, the stub feature that allows .cmdline to be
replaced by what's in LoadOptions ends up copying nothing/random
data to the kernel cmdline resulting in different kinds of boot
problems.
To fix this, add a check to see if LoadOptions contains data
before replacing the .cmdline.

coredump: when storing an incomplete coredump, add COREDUMP_TRUNCATED=yes
We logged about this, but did not attach information directly to the log
entry. It *would* be nice to log the full untruncated size, but afaict, to do
this, we would have to read the full data from the kernel. Doing this just to
log that information seems a bit excessive, in particular when the limit could
be set quite low. So for now let's just add a boolean field.
coredump: do not try to access unitialized CONTEXT_COMM field
Most of the fields in the context array come from the kernel (passed
through argv), but two are special: comm and exe. We allocate them
ourselves. We forgot to initialize context[CONTEXT_COMM] with the value
we allocated (introduced in 9aa820231414baa28e6bf02a033932cb69ff6b8b).
To simplify things, just set context[CONTEXT_COMM] and context[CONTEXT_EXE],
and free those two fields at the end.
coredumpctl: implement --since/--until (-S/-U) for info/list verbs
Implement --since/--until (-S/-U) in the same fashion as journalctl.
This lets the user filter the results a bit so it would be easier to
find relevant info in case there were many core dumps.
Let's just check the unified level, directly. There's really no value in
wrapping cg_unified_controllers() with this, i.e. potentially do string
comparison when there's no reason to.
Also, this makes the clal more alike cg_hybrid_unified().
cgroup: change cg_unified() to possibly return errors again
We use our cgroup APIs in various contexts, including from our libraries
sd-login, sd-bus. As we don#t control those environments we can't rely
that the unified cgroup setup logic succeeds, and hence really shouldn't
assert on it.

journal: avoid duplicated call to get cgroup path (#5404)

cgroup-util: cache all cg_is_*_wanted answers, disable /sys/fs/cgroups/unified on unified
If we encounter an error in proc cmdline parsing, just treat that as permanent,
i.e. the same as if the option was not specified. Realistically, it is better
to use the same condition for all related mounts, then to have e.g.
/sys/fs/cgroup mounted and /sys/fs/cgroup/unified not. If we find something is
mounted and base our answer on that, cache that result too.
Fix the conditions so that if "unified" is used, make sure any "hybrid" mounts
are not mounted.
man: update descriptions of argument-less kernel cmdline args
This updates the man page for the changes introduced in 1d84ad944520fc3e062ef518c4db4e1d3a1866af.
"=" is kep if the option is predominantly used with an argument, and dropped
otherwise.
v2:
- update also description of log_color
- drop '=' in all cases where it is optional
(previous rule of dropping it only in some cases was just too arbitrary.)
It is expected that general-purpose distributions might want to override this.
This commit is made separate from grandparent to make it easy to revert if
needed.
v2:
- use hybrid as the default
(We tested that the default of unified seems boot correctly everywhere and behave
correctly in general, but it is incompatible with docker/lxc and probably some
other tools, so for now we default to hybrid. The new "hybrid" mode should work
be OK for those tools.)

udev: Introduce UDEV_PROPAGATE_LOG macro (#5302)
As per commit 25e773e "udev: switch to systemd logging functions"
Now log_set_max_level() in udev_new() overwites system wide log level.
Propagate the udev.conf setting to log_set_max_level()
only if udev_new() is called from within udevd or one of its helpers.
Introduce a UDEV_PROPAGATE_LOG macro that we set with -D on
the gcc command line for all udev binaries we build, but not
for any others. The log_set_max_level() call is guarded by an
ifdef check for that macro, so that it only effects the various
udev binaries.
If our netlink input buffer overruns the kernel will send us ENOBUFS on
the next recvmsg(). Don't consider this a complete failure resulting in
closing of the netlink socket. Instead, simply continue (after debug
logging).
Of course, ideally we'd have a better strategy for this, and would have
a way to resync if this happens (as well as a scheme for cancelling all
ongoing asynchronous transactions), but for now let's at least not choke
fatally, and simply accept that we lost some messages and continue.
Note that if we lose messages when synchronously waiting for an
operation to complete, we'll still propagate the ENOBUFS up, to make the
individual transaction fail.
See: #5398
(This bug does not properly fix the issue, hence we should leave the bug
open.)
