shared/pam-util: add pam_syslog_errno() wrapper that sets errno
So far our pam code was using strerror_safe(). But that's not a good approach,
because strerror_safe() is not thread-safe, and the pam code is "library code"
that should be thread-safe. In fact, the whole effort to use strerror() is
unnecessary, because pam_syslog() is documented to support %m. The
implementation in linux-pam simply uses vasprintf(). If we use %m too, we get
rid of the issue. The wrapper sets errno temporarily from the argument.
Apparently some PAM consumers run multiple PAM stacks in threads, so we should
avoid non-thread-safe code.
The new helper returns PAM_BUF_ERR for ENOMEM, and PAM_SERVICE_ERR in other
cases. This may change the returned code in some cases, but I think a) it
doesn't matter much, b) it's probably for the better. E.g. we might now return
PAM_SERVICE_ERR if the dbus message is borked, and PAM_SERVICE_ERR seems
appropriate.

network: don't forget old RAs when a new one arrives
IPv6 Neighbor Discovery lets us autoconfigure a link's IPv6 addresses,
routes, DNS servers, and DNS search domains by listening for Router
Advertisement (RA) packets broadcast by one or more routers on the link.
Each RA can contain zero or more "options," each describing one piece of
configuration (e.g. a single route).
Currently, when we receive an RA from a router, we delete any addresses,
routes, etc. that originated from that router's previous RAs unless
they're also present as options in the new RA.
That behavior is a violation of RFC 4861[1]. In Section 9, the RFC
states that
Senders MAY send a subset of options in different packets. ... Thus,
a receiver MUST NOT associate any action with the absence of an
option in a particular packet. This protocol specifies that
receivers should only act on the expiration of timers and on the
information that is received in the packets.
Several other passages in the RFC reiterate this. Section 6.2.3:
A router MAY choose not to include some or all options when sending
unsolicited Router Advertisements.
Section 6.3.4:
Hosts accept the union of all received information; the receipt of a
Router Advertisement MUST NOT invalidate all information received in
a previous advertisement or from another source.
At least one consumer router in production today, the Google Nest Wifi,
often sends RAs that omit its global IPv6 prefix. When current versions
of systemd-networkd receive those RAs, they immediately delete the
interface's global IPv6 address, which breaks IPv6 connectivity.
Fix the issue by removing the invalidation logic entirely. It's not
needed at all, since we already invalidate addresses, routes, and DNS
configuration when the interface goes down or their lifetimes expire.
This fix does have the side effect of preventing changes to the .network
file (e.g. denylisted prefixes, whether to add routes from RAs) from
taking effect as soon as a new RA arrives. Instead, a full interface
reconfiguration is needed. But triggering those changes on RA receipt
was already rather arbitrary and out of the administrator's control, so
I think this change is fine.
commit
69203fba700e ("network: ndisc: remove old addresses and routes
after at least one SLAAC address becomes ready") introduced this
behavior. commit
50550722e3ba fixed it partially, by preventing one
router's RAs from invalidating another router's configuration.

manager: fix/change evaluation of ConditionFirstBoot
The code to evaluate the kernel command line option was busted because it
was doing 'return b == !!r' at a point where 'r > 0'. Thus we'd return "true"
in both cases:
$ SYSTEMD_PROC_CMDLINE=systemd.condition-first-boot build/systemd-analyze condition 'ConditionFirstBoot=true'

$ SYSTEMD_PROC_CMDLINE=systemd.condition-first-boot build/systemd-analyze condition 'ConditionFirstBoot=false'
test.service: ConditionFirstBoot=false succeeded.
Conditions succeeded.
We only use 'ConditionFirstBoot=true' in units, so this wasn't noticed.
But I think the logic is broken in general: the condition should evaluate as
true only during initial boot. If we rerun the units at later points, we should
not consider ConditionFirstBoot to be true.
Also, the first boot logic is also used in pid1 itself. AFAICT, for two
things: in first boot machine-id is initialized transiently (this allows
first-boot operations to be restarted if boot fails), and preset-all is
executed. But this logic was different and separate from the logic to
evaluate ConditionFirstBoot. The distinction is abolished, and the operations
in pid1 now use the same logic as ConditionFirstBoot, which means that the
kernel command line option is checked, and condition_test_first_boot()
just tests whether pid1 thinks we're in first boot.
This makes things easier to grok for the user: there's just one condition for
"first boot" and it applies to both pid1 and units.
