We have two typical styles of 'ret' param assignment + retval:
1) < 0 on actual error, 0 on nothing (ret == NULL), > 0 on something
2) recognizable errno on nothing, < 0 on other errors, >= 0 on something
but never use both at the same time.
Currently, Fedora's systemd RPM doesn't own systemenvgeneratordir
(ie., /usr/lib/systemd/system-environment-generators) [1] because it's
not created when systemd is installed. In contrast, userenvgeneratordir
(ie., /usr/lib/systemd/user-environment-generators) is created, unless
the environment-d Meson option is explicitly disabled.
While this can be worked around elsewhere, it's better if the upstream
build system created the directories consistently. It will avoid
repetition, and prevent silly bugs or deviations from creeping in.

run_command()'s working directory is documented as undefined but it
seems to be the current source directory as when the -ftime-trace
clang option is enabled, -.json is written to src/basic/meson.build
every time meson is run.
Let's make sure the command is executed in the build directory so that
any auxiliary files are written there as well.
Document .link .network and .netdev file type distinctions in early
introductory text, and document distro-specific need to sync link files
with early-boot copies, see Debian bug 1005282:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1005282 for an
example.
These are various commits that were required to get things compiling
after running IWYU. I think all of them make sense on their own, hence
this split PR to merge them ahead of time.
We currently include these transitively but to allow using IWYU to
remove headers later, let's add these as direct includes so the IWYU
changes don't break compilation.
Currently, NOTIFY_READY from daemon-util.h conflicts with NOTIFY_READY
from NotifyState from service.h so let's rename the constants to avoid
the conflict.
When compiling the source files, we know static is going to be available
so there's no need to use the macro from _sd-common.h and we can just use
static instead.
Continuation of #36734
Apparently I was wrong about everything under `/proc/` being seq_file,
but at least there're some more to convert and we can leverage our
helper func while doing so.
- Drop effectively unused "terminator" param, imply whitespace
- Make ret param optional
- Return ENODATA if the requested key is not found, rather than
ENOENT
- Turn ENOENT -> ENOSYS if /proc/ is not mounted
- Don't skip whitespaces before ':', nothing needs this handling
anyways
- Remove the special treatment for all "0"s. We don't actually
use this for capabilities given pidref_get_capability() exists
- Switch away from read_full_virtual_file() - files using "field"
scheme under /proc/ seem all to be "seq_file"s (refer to
da65941c3e for details on file types)
When linux_exec() fails, the initrd pages cleanup attempts to run,
and an assertion is triggered:
../src/boot/linux.c:125@linux_exec: Error loading kernel image: Security violation
../src/boot/util.h:81@cleanup_pages: Error freeing pages: Not found
../src/boot/log.c:30@efi_assert: systemd-boot: Assertion 'r == EFI_SUCCESS' failed at ../src/boot/util.h:82@cleanup_pages, halting.
(log message is new)
This was introduced by https://github.com/systemd/systemd/pull/36715
Before that change, given the argument to xmalloc_pages() was passed as EFI_SIZE_TO_PAGES(n_pages), that's
what ended up in Pages.n_pages. After this change, n_pages gets assigned without being transformed by
EFI_SIZE_TO_PAGES, so the cleanup can find them again. That change causes the assertion failure to trigger.
Changing this to .n_pages = EFI_SIZE_TO_PAGES(n_pages) fixes the assertion.
Follow-up for c5a5046792
We were compiling the same resolved sources over and over again (up to
10 times) which had a substantial effect on build times. Let's make sure
we only compile the resolved sources once by having one static library
containing the objects for all the resolved sources.
While we're at it, get rid of unnecessary variables and includes in the
resolve meson file and generally clean things up a bit.

We usually don't care, but here the existence of socket
is public API to a certain degree and signals availability
of the service (userdbd in particular, oomd is checked in
core-varlink.c). Hence let's be more careful and remove them
if stopped.
The current arrangement of service and socket units is
sort of all over the place. Let's clean it up a little,
roughly following the principles below:
- socket units have implicit ordering deps (not to be confused
with default ones which are subject to DefaultDependencies=)
before associated service, so drop any explicit After=
- If socket can be enabled, remember to link to it in service
via Also= and Sockets= (the latter replaces Wants=).
If the service Requires= socket however, Sockets= is omitted.
- If socket is statically enabled, no need for service
to pull it in - machined
Currently, if systemd-networkd-wait-online is started with --dns, and
systemd-resolved is not running, it will exit with an error right away.
Similarly, if systemd-resolved is restarted while waiting for DNS
configuration, systemd-networkd-wait-online will not attempt to
re-connect, and will potentially never see subsequent DNS
configurations.
Improve this by adding socket units for the systemd-resolved varlink
servers, and re-establish the connection in systemd-networkd-wait-online
when we receive `SD_VARLINK_ERROR_DISCONNECTED`.
Otherwise passing invalid data means asserts get hit instead of
handling it gracefully. Other verbs already do the same checks.
