Looked for definitions of functions using the *_compare_func() suffix.
Tested:
- Unit tests passed (ninja -C build/ test)
- Installed this build and booted with it.
When networkd has not connected and setting hostname/timezone is
requested, the operation is delayed, not canceled. So, logging in
debug level is sufficient for the corresponding log message.
Closes#9699.
Now the setting MTU is embedded into the link_up message which makes it
incapable of setting MTU if link is up. MTU can be set while Link is up.
Closes#9254
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.
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.
They are not needed, because anything that is non-zero is converted
to true.

> 6.3.1.2: When any scalar value is converted to _Bool, the result is 0 if the

This fixes an insecure use of tainted data as argument to functions that
allocate memory and read from files, which could be tricked into getting
networkctl to allocate a large amount of memory and fill it with file
data.
This was uncovered by Coverity. Fixes CID 1393254.
This should fix a leak of the allocated Prefix if sd_radv_prefix_new
fails for some reason.
The code was already initializing prefix to NULL and using TAKE_PTR to
return it, so only the _cleanup_ was missing.
Fixes Coverity finding CID 1382976.
This is mostly fall-out from d1a1f0aaf0,
however some cases are older bugs.
There might be more issues lurking, this was a simple grep for "%m"
across the tree, with all lines removed that mention "errno" at all.
