If openat_report_new() fails, then 'made_file' will be false, as no file
was created, hence there's no need to skip the unlinkat() explicitly
early, given that we check for 'made_file' anyway in the error path. The
extra error code checks are hence entirely redundant.
We have two distinct implementations of the post hook.
1. For SELinux we just reset the selinux label we told the kernel
earlier to use for new inodes.
2. For SMACK we might apply an xattr to the specified file.
The two calls are quite different: the first call we want to call in all
cases (failure or success), the latter only if we actually managed to
create an inode, in which case it is called on the inode.
We noticed some failures because we have code that connects to user
managers by setting DBUS_SESSION_BUS_ADDRESS without setting XDG_RUNTIME_DIR.
If that's the case, connect to the user session bus instead of the
private manager bus as we can't connect to the latter if XDG_RUNTIME_DIR
is not set.
The structure of DNR options is considerably more complicated than most
DHCP options, and as a result the fuzzer has poor coverage of these code
paths.
This adds some DNR packets to the fuzzing corpus, not with the intent of
capturing some specific edge case, but with the intent to rapidly
improve the fuzzers' coverage of these codepaths by giving it a valid
example to begin with.
Also include an ndisc router advert with a few Encrypted DNS options,
for the same purpose.
Implement serialization/deserialization for DNR servers. This re-uses
the string format in place for user configuration of DoT servers, and as
a consequence non-DoT servers are discarded when recording the link
configuration, for correctness.
This also enables sd-resolved to use these servers as it would other DNS
servers.
This option will control the use of DNR for choosing DNS servers on the
link. Defaults to the value of UseDNS so that in most cases they will be
toggled together.
Now that mkosi supports generating UKI profiles, let's make use of
that to generate the UKI profiles required for the test instead of
doing it within the test itself.
Otherwise, when the test is executed on a system with signed PCRs,
cryptenroll will automatically pick up the public key from the UKI
which results in a volume that can't be unlocked because the pcrextend
tests appends extra things to pcr 11.
Let's provide a mechanism to select the number of screen columns for
rebreaking comments in Varlink IDL connected to a TTY, by honouring the
$COLUMNS env var then too. Previously we'd only honour when connected to
a TTY, but it's also useful otherwise for rebreaking ridiculously long
comments, hence honour it in this case too.
Previously, we were using touch(), which usually works fine, because the
path should always refer to an existing directory, in which case it just
updates the timestamp. However, if the dir does not exist yet (which
shouldn't happen), it would be created as regular file, which is just
wrong.
Hence, let's instead create the dir as dir if it is missing, and then
update its timestamp.
