The key macros added in commit 6fe95d3020 look strange at first sight.
Add a comment with just the tablet name after each line, so that it's
obvious that these lines address device-specific issues of the EFI
firmware, and not broken/old code.

This is an attempt to clean up the POP3/SMTP/LPR/… DHCP lease server
data logic in networkd. This reduces code duplication and fixes a number
of bugs.
This removes any support for collecting POP3/SMPT/LPR servers acquired
via local DHCP client releases since noone uses that, and given how old
these protocols are I doubt this will change. It keeps support for
configuring them for the dhcp server however.
The differences between the DNS/NTP/SIP/POP3/SMTP/LPR configuration
logics are minimized.
This removes the relevant symbols from sd-network.h (which is an
internal API only at this point after all).
This is unfortunately not well test, given the old code for this had
barely any tests. But the new code should not perform worse at least,
and allow us to release, since it corrects some interfaces visible in
the .network configuration format.

Strictly speaking this is a compat breakage, but given the tool was
added only in the last release, let's try to sail under the radar, and
fix this early before anyone notices it wasn't supported always.
When a key is pressed, the EFI firmware gives us a 64-bit word that
contains the modifier key code in the upper 32 bits, the scan code in
the middle 16 bits, and a unicode character in the low 16 bits.
Some bogus EFI firmwares will put the unicode character in the scan code
area, for instance on the EZpad mini 4s tablet.
Others will even put the unicode character in both the scan code and
unicode areas. This is the case for instance on the Teclast X98+ II
tablet.
Add workarounds for these corner cases, only for the carriage return key
right now. Some more workarounds may be needed, e.g. for volume keys,
but I cannot test it.
Partially fixes#8466.

The original logic was logging an "ignored" debug message, but it was still
going ahead and calling proc_cmdline_parse_given() on the NULL line. Fix that
to skip that explicitly when the EFI variable wasn't really read.
Depending on if the system has been scheduled for shutdown or for reboot pring the corresponding message (and not only "Shutdown"). Prtinting the "wrong" message when rebooting will mislead and panic people. I get these messages via cron from remote servers and it would be bad if those systems actually *did* shut down, as the email from cron is telling me. Those messages cause an adrenalin spike in our team, which wouldn't happen, if the message was "correct"
Fixes#16129.
Cache it early in startup of the system manager, right after `/run/systemd` is
created, so that further access to it can be done without accessing the EFI
filesystem at all.
half of find_hibernation_location() logged at debug level, the other
half logged at error level, and the third half didn't log at all.
Let's clean this up somewhat. Since can_sleep() is probably more
a library-style function let's downgrade everything to LOG_DEBUG and
then make sure sleep.c logs at error level, as the main program.
Prompted by the discussion on #16110, let's migrate more code to
fd_wait_for_event().
This only leaves 7 places where we call into poll()/poll() directly in
our entire codebase. (one of which is fd_wait_for_event() itself)
Use -Dstandalone-binaries=yes to enable building and installing this standalone
version of the binary without a dependency on the systemd-shared solib.
Also move the list of sources for systemd-tmpfiles to its own meson.build file.
"less" doesn't properly reset its terminal on SIGTERM, it does so only
on SIGINT. Let's thus configure SIGINT instead of SIGTERM.
I think this is something less should fix too, and clean up things
correctly on SIGTERM, too. However, given that we explicitly enable
SIGINT behaviour by passing "K" to $LESS I figure it makes sense if we
also send SIGINT instead of SIGTERM to match it.
Fixes: #16084
unit_choose_id() is about marking one of the aliases of the unit as the main
name. With the preparatory work in previous patches, all aliases of the unit
must have the same instance, so the operation to update the instance is a noop.
Upon an incoming connection for an accepting socket, we'd create a unit like
foo@0.service, then figure out that the instance name should be e.g. "0-41-0",
and then add the name foo@0-41-0.service to the unit. This obviously violates
the rule that any service needs to have a constance instance part.
So let's reverse the order: we first determine the instance name and then
create the unit with the correct name from the start.
There are two cases where we don't know the instance name:
- analyze-verify: we just do a quick check that the instance unit can be
created. So let's use a bogus instance string.
- selinux: the code wants to load the service unit to extract the ExecStart path
and query it for the selinux label. Do the same as above.
Note that in both cases it is possible that the real unit that is loaded could
be different than the one with the bogus instance value, for example if there
is a dropin for a specific instance name. We can't do much about this, since we
can't figure out the instance name in advance. The old code had the same
shortcoming.
They were added recently in acd1987a18. We can
make them more informative by using unit_type_to_string() and not repeating
unit names as much. Also, %m should not be used together with SYNTHETIC_ERRNO().
We would check that the instance is present in both units (or missing in both).
But when it is defined, it should be the same in both. The comment in the code
was explicitly saying that differing instance strings are allowed, but this
mostly seems to be a left-over from old times. The man page is pretty clear:
> the instance (if any) is always uniquely defined for a given unit and all its
> aliases.
We allocated the names set for each unit, but in the majority of cases, we'd
put only one name in the set:
$ systemctl show --value -p Names '*'|grep .|grep -v ' '|wc -l
564
$ systemctl show --value -p Names '*'|grep .|grep ' '|wc -l
16
So let's add a separate .id field, and only store aliases in the set, and only
create the set if there's at least one alias. This requires a bit of gymnastics
in the code, but I think this optimization is worth the trouble, because we
save one object for many loaded units.
In particular set_complete_move() wasn't very useful because the target
unit would always have at least one name defined, i.e. the optimization to
move the whole set over would never fire.
