029115a23e Drop .deb package from release target
We're moving to automated releases using GitHub Actions, but the bots
cannot be trusted to do .deb packaging yet, so let's drop that from
the official release target for now.

d7576c7fc0 syslogd.service: use journald socket, not /dev/log
This patch fixes integration with systemd-journald, and also sets the
now mandatory KillMode.

When running on systems with systemd-journald certain considerations
must be taken.  These are listed here:

  https://www.freedesktop.org/wiki/Software/systemd/syslog/

In it simplest form, the system as a whole logs through journald and
a BSD syslog daemon then gets its log messages from journald.

NOTE: due to issues with the Debian packaging of rsyslog, the sysklogd
      packages cannot be used to replace rsyslog.  First rsyslog must
      be purged to clear the syslog.socket symlink, then sysklogd can
      be installed.

287e009514 Fix #35: syslogd man page lists -v as verbose mode, is version
When syncing with the FreeBSD man page the audit missed this option.
The man page should detail what the daemon does, even though in this
case it would've been nice to have the FreeBSD behahvior for -v.

fc5096f1c2 syslogd: support for extracting user level messages from /dev/kmsg
It is well established practise on Linux to use /dev/kmsg (old or
new API) before syslogd is up (and /dev/log exists).  This patch
enables support for extracting non-kernel log messages and logging
them with their proper facility and priority.

52fc3f7176 Ensure received data is nul terminated, found by Coverity Scan
Coverity found two possible untrusted loop bounds, in unix_cb() and
inet_cb(), that were indeed possibly unterminated strings.  These
were classified as medium.  A third finding, marked high, was found
in kernel_cb(), which upon further investigation seems bogus.

This patch terminates the buffers received in unix_cb() and inet_cb()
but only changes to 0 from \0 termination in kernel_cb().

e5ee2446a0 Follow-up to 92a4fb3: allow kernel log dupes around edge of seqno
Although hihgly unlikely, if the kernel log sequence number (seqno)
reaches the end of its MAX value (18446744073709551615) we allow for
dupes to handle the wrap-around back to zero (0) in the counter.

92a4fb3318 Fix #29: prevent repeating kernel messages when syslogd is restarted
This patch fixes the problem with kernel messages being repeated when
syslogd is restarted at runtime.  This is achieved by caching the last
seqno read from /dev/kmsg to /run/syslogd.cache.  The latter is usually
a ram disk these days so it should be a fairly quick op.

Excessive updates are prevented by only caching after handling all
callbacks in the socket_poll() loop, and only updating the cache
if there has been any new kernel messages since last update.

eb454d7d37 Fix #28: log messages stuck in 1969
The timer_now() API, introduced in 2019, returns time relative to boot.
Useful for relative time comparisons, but when used for absolute time,
e.g. for log messages, it must be offset with boot_time.

This patch fixes issue #28, but also wall messages, which exhibits the
same problem.
