This probably predates our introduction of streq_ptr(). Let's drop this
now however, as we actually want this to be NULL, further down, and
handle that just fine. In particular as all the special cases we have
explicitly set this to NULL anyway.
No real change in behaviour, just some normalization of handling.
If PAMName= is used we'll spawn a PAM session for the service, and leave
a process around that closes the PAM session eventually. That process
must close the "exec_fd" that we use to implement Type=exec. After all
the logic relies on the fact that execve() will implicitly close the
exec_fd, and the EOF seen on it is hence indication for the service
manager that execve() has worked. But if we keep an fd open in the PAM
service process, then this is not going to work.
Hence close the fd explicitly so that it definitely doesn't stay pinned
in the child.
Otherwise, log_netdev_xyz() does not provide netdev name if it is called
in done(). It is hard to debug.
This should not change any effective behavior, at least with the current
implementation of done() per netdev kind.
session-status automatically uses "auto" if no ID is specified,
but show-session shows the manager's properties. Let's document
these special values so that users of show-session can benefit too.
This new transaction result is emitted when the upstream server
indicates a fatal error that we will not try to recover from.
Currently, it is emitted when a validating recursive resolver reports an
error validating dnssec records for a domain. The extended error message
should help give context to the admin.
Some fields of the DnsPacket are not populated until we extract an
answer, like p->opt, despite being referenced by macros like
DNS_PACKET_RCODE. We can reorder some of the basic checks to follow
dns_packet_extract.
The current check checks for n_sigbus_queue
being greater than or equal to SIGBUS_QUEUE_MAX,
when it should be just greater than as
n_sigbus_queue being SIGBUS_QUEUE_MAX indicates
that the queue is full, but not overflowed.
(Hopefully) a temporary workaround for #30573 where starting a user
session when PID 1 is rate limited stalls even after it leaves the rate
limited state:

The issue appeared after ee07fff03b which does a bunch of mounts/umounts
that get PID 1 into a rate limited state, and is frequent enough to be
annoying, so let's temporarily bump the rate limit to alleviate that.
Currently, networkd does not change pool size dynamically, so this
should not change behavior. But if networkd does that, then forgetting
leases causes that an address still used by a client may be assigned to
another host.
