Zbigniew Jędrzejewski-Szmek 8f04a1ca2b meson: also allow setting GIT_VERSION via templates
GIT_VERSION is not available as a config.h variable, because it's rendered
into version.h during builds. Let's rework jinja2 rendering to also
parse version.h. No functional change, the new variable is so far unused.

I guess this will make partial rebuilds a bit slower, but it's useful
to be able to use the full version string.

Christian Brauner a6d1760024 build: preserve correct mode when generating files via jinja2
When using "capture : true" in custom_target()s the mode of the source
file is not preserved when the generated file is not installed and so
needs to be tweaked manually. Switch from output capture to creating the
target file and copy the permissions from the input file.

Luca Boccassi c2b2df604b tree-wide: avoid uninitialized warning on _cleanup_ variables
With some versions of the compiler, the _cleanup_ attr makes it think
the variable might be freed/closed when uninitialized, even though it
cannot happen. The added cost is small enough to be worth the benefit,
and optimized builds will help reduce it even further.

Franck Bui 0ef1adf512 vconsole-setup: downgrade log message when setting font fails on dummy console
Since commit 883eb9be98, vconsole-setup might be
called again to operate on dummy console where font operations are not
supported but where it's still important to have the correct keymap set [0][1].

vconsole-setup is mainly called by udev but can also be run via a dependency of
an early service. Both cases might end up calling vconsole-setup on the dummy
console.

The first case can happen during early boot even on systems that use (instead
of the dummy console) a "simple" video console driver supporting font
operations (such as vgacon) until a more specific driver (such as i915) takes
the console over. While this is happening vgacon is deactivated and temporarly
replaced by the dummy console [2].

There are also other cases where systemd-vconsole-setup might be called on
dummy console especially during (very) early boot. Indeed
systemd-vconsole-setup.service might be pulled in by early interactive services
such as 'dracut-cmdline-ask.service` which is run before udev.

If that happens on platforms with no grapical HWs (such as embedded ARM) or
with dummy console initially installed until a driver takes over (like Xen and
xen-fbfront) then setting font will fail.

Therefore this patch downgrades the log message emitted when setting font fails
to LOG_DEBUG and when font operations is not implemented like it's the case for
the dummy console.

Fixes: #16406.

Tim Ruffing 883eb9be98 vconsole: Don't skip udev call for dummy device
Kernel 4.19 supports deferred console takeover [0], i.e., fbcon will
take over the console only when the first text is displayed on the
console. Before that event, only the dummy console is active. Our
currently udev rules call systemd-vconsole on every vtcon except for
dummy consoles. Thus the exception for dummy consoles prevents a call
to systemd-vconsole when no text is displayed on the console, and as a
consequence, the keymap will not be set in that case. This is wrong and
leads to issues when keyboard input is expected without text on the
console, e.g., when a graphical password prompt is used in the boot
process.

This reverts commit 6b169c13ec,
which introduced the exception for dummy devices to save unnecessary
udev calls.

Fixes #10826.

Lennart Poettering 818bf54632 tree-wide: drop 'This file is part of systemd' blurb
This part of the copyright blurb stems from the GPL use recommendations:

https://www.gnu.org/licenses/gpl-howto.en.html

The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.

hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

Zbigniew Jędrzejewski-Szmek 11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

Lennart Poettering c10d6bdb89 macro: introduce new TAKE_FD() macro
This is similar to TAKE_PTR() but operates on file descriptors, and thus

Lennart Poettering ae2a15bc14 macro: introduce TAKE_PTR() macro
This macro will read a pointer of any type, return it, and set the
pointer to NULL. This is useful as an explicit concept of passing
ownership of a memory area between pointers.

This takes inspiration from Rust:

https://doc.rust-lang.org/std/option/enum.Option.html#method.take

and was suggested by Alan Jenkins (@sourcejedi).

It drops ~160 lines of code from our codebase, which makes me like it.
Also, I think it clarifies passing of ownership, and thus helps
readability a bit (at least for the initiated who know the new macro)

Lennart Poettering 7d4904fe7a process-util: rework wait_for_terminate_and_warn() to take a flags parameter
This renames wait_for_terminate_and_warn() to
wait_for_terminate_and_check(), and adds a flags parameter, that
controls how much to log: there's one flag that means we log about
abnormal stuff, and another one that controls whether we log about
non-zero exit codes. Finally, there's a shortcut flag value for logging
in both cases, as that's what we usually use.

All callers are accordingly updated. At three occasions duplicate logging
is removed, i.e. where the old function was called but logged in the
caller, too.

Lennart Poettering 4c253ed1ca tree-wide: introduce new safe_fork() helper and port everything over
This adds a new safe_fork() wrapper around fork() and makes use of it
everywhere. The new wrapper does a couple of things we previously did
manually and separately in a safer, more correct and automatic way:

1. Optionally resets signal handlers/mask in the child

2. Sets a name on all processes we fork off right after forking off (and
   the patch assigns useful names for all processes we fork off now,
   following a systematic naming scheme: always enclosed in () – in order
   to indicate that these are not proper, exec()ed processes, but only
   forked off children, and if the process is long-running with only our
   own code, without execve()'ing something else, it gets am "sd-" prefix.)

3. Optionally closes all file descriptors in the child

4. Optionally sets a PR_SET_DEATHSIG to SIGTERM in the child, in a safe
   way so that the parent dying before this happens being handled
   safely.

5. Optionally reopens the logs

6. Optionally connects stdin/stdout/stderr to /dev/null

7. Debug logs about the forked off processes.
