8d801e35cb didn't take into account
upwards iteration of entry items when we're working on a corrupted
journal file. Instead of moving to the previous entry array, we'd
always move to the next array, regardless of the iteration direction.
To fix this, we introduce bump_entry_array() that moves to the next
or previous entry array depending on the given direction. Since the
entry array chains are singly linked lists, we have to start iterating
from the front to find the previous array. We only reach this logic
if we're working on a corrupted journal file so being slow here shouldn't
matter too much.
Fixes an assertion failure "pd->type == SD_DHCP6_OPTION_IA_PD" in dhcp6_option_append_pd().
Something similar was done in commit 26a63b8132 ('sd-dhcp6-client: Fix
sending prefix delegation request (#17136)'). The justification is
probably the same.
In D-Bus, clients connect to a bus (the usual case), or use direct
questions to each other (the unusual case). A bus is a program one can
connect to and implemented by dbus-daemon or dbus-broker. HOwever,
busses never connect between each other, that doesn't exist. Hence don't
claim so.
This is probably confusion about the fact that sd-bus calls D-Bus
connection objects just "sd_bus" for simplicity, given they are used in
99% of the cases to connect to a bus — only in exceptional cases they
are used for direct connections between peers without involving a bus.

Apparently the error code fallocate() returns if hole punching is not
supported is not too well defined (man page just says "an error is
returned"), hence let's accept the usual set of errors, and the
normalize it to EOPNOTSUPP, and generate a clear error message in this
case.
This basically reverts #22079.
Stopping the watchdog is wrong. The reboot watchdog is supposed to cover
the whole time from the point when systemd start systemd-reboot until the
hardware resets.
Otherwise the system may hang in the final shutdown phase.
Add a comment, why keeping the watchdog running is correct here.
If watchdog_set_device() is not called before open_watchdog() then
'watchdog_device' remains 'NULL' while the device is open.
As a result, the "same device" check in watchdog_set_device() does not work
correctly: If no device is specified (e.g. from watchdog_free_device())
then the current fd is not closed.
Fix this by setting 'watchdog_device' to the correct device during
open_watchdog()
Since a long time the D-Bus spec knows a special bit in its message
header for indicating that "interactive" authentication is OK. The
original hostnamed API is before that was added hence most functions
expose that boolean as explicit argument.
For new added functions let's get rid of it, the message flag is good
enough and replaces it with complete functionality.
No new APIs should carry the "interactive" boolean flag explicitly as
argument anymore.

The warning is correct, since we don't inherit the necessary
unittest.TestCase class, but that's on purpose, since the Utilities
class is not supposed to be instantiated on its own, but should
complement other classes' definitions which do inherit from the
unittest.TestCase class.
It currently works because `\(` and `\)` are not valid escape sequences,
so they're not treated differently. Using raw strings (or double
backslashes) is a more correct solution.
Multiline comments are converted to docstrings only when they're the
first statement in a function/method. Even though they're still a no-op
otherwise, let's use "true" comments to make pylint happy.
Note to self: should I ever become a black hat hacker, this is how I'd
hide a vulnerability. ;-)
(No, this one is not a vulnerability)

We have the journal file open already, hence reference it via the fd
insted of the file name. After all, some other tool might have
renamed/deleted it already.
Let's not actually reuse the fd though, since we want a separate file
offset for the copying, hence just make it simply and reopen via
/proc/self/fd/.

to let them use reproducible identifiers, which should make it possible
to really use files copied from OSS-Fuzz to reproduce issues on
GHActions and locally. Prompted by https://github.com/systemd/systemd/pull/22365
