- use `udevadm wait` instead of `udevadm info --wait-initialized`,
- use `timeout` command instead of the fixed time sleep,
- add basic tests for #25106,
- add brief comment about #25115.
When running the tests in a chroot /sys/ might be writable, but it
doesn't mean udev will be running

We generate a "version string" that is reported by various tools. This patch
changes this version string to use the characters specified for the version
string in the Boot Loader Specification. We start using the special characters
we have in the spec for this exact purpose and thus fix version comparisons.
We also stop using '+' which is not part of the allowed charset and is used for
boot attempt counting and should not be part of the version string.
The version string is (among other places) used in sd-boot and the comparison
result is used by 'bootctl update' to decide whether to install a new binary.
Before, because 'nn-rc1' compares higher than 'nn', we would refuse to upgrade
pre-release versions.
The boot loader is the primary motivation. I'm not aware of programatic version
comparisons in other places, but it makes sense to use the same versions string
everywhere.
(This patch effectively only matters for non-distro builds, because distro
builds presumably use -Dversion-tag to set something meaningful. Ideally, those
version strings are compatible with our version strings, but this is outside of
our control.)
This performs the same semantic transformation as the Coccinelle
script 'strdupa.cocci'.
Somehow the existing semantic patch is not properly triggering on
this 'string_replace_char' test.
Then, try to drop multiple protocol specifiers at the end.
Strictly speaking, this breaks backward compatibility:
if eth0 and eth0.42 exists, then previously,
echo 'nameserver 192.168.0.1' | resolvconf -a eth0.42
adds the DNS server to eth0 instead of eth0.42, as we unconditionally
dropped the specifier after the last dot, and
echo 'nameserver 192.168.0.1' | resolvconf -a eth0.42.dhcp
adds the DNS server to eth0.42. However, with this commit, now
the both commands add the DNS server to eth0.42. But, hopefully,
this should be preferable behavior.
Fixes#25032.
We treat symlinks to unit files outside of the search path differently from
symlinks to unit files *in* the search path. The former are "linked" unit
files, while the latter are enablement symlinks and such and will be removed
when disabling the unit.
The history of the check for in_search_path() is interesting: this condition
was added already in the first version of the code in
830964834f. Since the beginning, matching
arguments would simply be ignored. I think this is dubious. The man page says:
> Link a unit file that is *not* in the unit file search paths
> into the unit file search path
But for backwards-compat, let's continue to silently do nothing for files
*in* the search path.
The case of symlinks to unit files underneath the search path, but in some
subdirectory, is less clear. We didn't check for this case, so it was
implicitly allowed. But that's just an oversight, we don't want to allow people
to create additional subhierarchies under our hierarchy. Let's check for this
case and refuse.
Closes#24605.
This adds a check for an allocation error for the calls to install_changes_add()
where we're plannig to return success from the call. In cases where we're
returning failure, it doesn't matter as much: the operation will fail anyway,
and if the allocation fails, we'll just get a less descriptive error message.
The machinery to report a good error message only works if the
error was registered with install_changes_add() and a file name. Otherwise
we only get a generic "Op failed: %m" message.
In some places -EINVAL is replaced by -EUCLEAN, so that we get the proper
error message.
The function was written to only return an error from internal allocation
failures, because when using it to create a bus message, we want to distinguish
a failed operation from an allocation error when sending the reply. But it
turns out that the only caller that makes this distinction checks that the
passed-in errno value ('type') is not negative beforehand. So we can make the
function pass 'type' value through, which makes most of the callers nicer.
No functional change.
