shared/calendarspec: when mktime() moves us backwards, jump forward
When trying to calculate the next firing of 'Sun *-*-* 01:00:00', we'd fall
into an infinite loop, because mktime() moves us "backwards":
Before this patch:
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
...
We rely on mktime() normalizing the time. The man page does not say that it'll
move the time forward, but our algorithm relies on this. So let's catch this
case explicitly.

resolved: don't accept responses to query unless they completely answer our questions
When we checking if the responses we collected for a DnsQuery are
sufficient to complete it we previously only check if one of the
collected response RRs matches at least one of the question RR keys.
This changes the logic to require that there must be at least one
response RR matched *each* of the question RR keys before considering
the answer complete.
Otherwise we might end up accepting an A reply as complete answer for an
A/AAAA query and vice versa, but we want to make sure we wait until we
get a reply on both types before returning this to the user in all
cases.
This has been broken for basically forever, but didn't surface until

ignore the auxiliary RRs included in CNAME/DNAME replies. Once that

Previously, when a process outputs something and exit just after
epoll_wait() but before process_child(), then the IO event is ignored
even if the IO event has higher priority. See #18190.
This can be solved by checking epoll event again after process_child().
However, there exists a possibility that another process outputs and
exits just after process_child() but before the second epoll_wait().
When the IO event has lower priority than the child event, still IO
event is processed.
So, this makes new epoll events and child events are checked in a loop
until no new event is detected. To prevent an infinite loop, the number
of maximum trial is set to 10.

When doing a CNAME/DNAME redirect let's first check if the answer we
already have fully answers the redirected question already. If so, let's
use that. If not, let's properly restart things.
This simply removes one call to dns_answer_reset() that was placed too
early: instead of resetting when we detect a CNAME/DNAME redirect, do so
only after checking if the answer we already have doesn't match the
reply, and then decide to *actually* follow it. Or in other words: rely

broken, we need to test it against the CNAME query we are currently
looking at.
The effect of this incorrect matching was that we'd assign the RRs to
the wrong section since we'd assume they'd be auxiliary answers instead
of primary answers.

resolved: let's tweak how we calculate TTL left
When responding from DNS cache, let's slightly tweak how the TTL is
lowered: as before let's round down when converting from our internal µs
to the external seconds. (This is preferable, since records should
better be cached too short instead of too long.) Let's avoid rounding
down to zero though, since that has special semantics in many cases (in
particular mDNS). Let's just use 1s in that case.

resolved: take shortest TTL of all of RRs in answer as cache lifetime
We nowadays cache full answer RRset combinations instead of just the
exact matching rrset. This means we should not cache RRs that are not
immediate answers to our question for longer then their own RRs. Or in
other words: let's determine the shortest TTL of all RRs in the whole
answer, and use that as cache lifetime.

man: specify that ProtectProc= does not work with root/cap_sys_ptrace
When using hidepid=invisible on procfs, the kernel will check if the
gid of the process trying to access /proc is the same as the gid of
the process that mounted the /proc instance, or if it has the ptrace
capability:
https://github.com/torvalds/linux/blob/v5.10/fs/proc/base.c#L723
https://github.com/torvalds/linux/blob/v5.10/fs/proc/root.c#L155
Given we set up the /proc instance as root for system services,
The same restriction applies to CAP_SYS_PTRACE, if a process runs with
it then hidepid=invisible has no effect.
ProtectProc effectively can only be used with User= or DynamicUser=yes,
without CAP_SYS_PTRACE.
Update the documentation to explicitly state these limitations.

ask-password-api: fix error handling on invalid unicode character
The integer overflow happens when utf8_encoded_valid_unichar() returns an error
code. The error code is a negative number: -22. This overflows when it is
assigned to `z` (type `size_t`). This can cause an infinite loop if the value
of `q` is 22 or larger.
To reproduce the bug, you need to run `systemd-ask-password` and enter an
invalid unicode character, followed by a backspace character.
