a1a5f020ed Harlan.Stenn@pfcs.com added two (very interesting) options to syslogd for
-current (Thanks Harald). However, on my attempt to try this on -STABLE,
I found that when forwarding to another host the actual messages gets lost.
This is due to a wrong index because when the -v option was added, the
indexes shifted one place.

9abae418f8 Remove a bogus dependency on the size of the inkernel msgbuf.
This change is likely to introduce a few linebreaks in the boot
messages, but that is not easy to solve without breaking syslogd
semantics.  Maybe the right  fix is to return an integral number
of lines from the kernel driver.

448c1dca85 Nobody ever seemed to be interested in reviewing these changes, and i
found that my syslogd is now running them for several months...

Add an option to syslogd to restrict the IP addresses that are allowed
to log to this syslogd.  It's too late to develop the inter-syslogd
communications protocol mentioned in the BUGS section, some 10 years
too late.  Thus, restricting the IP address range is about the most
effective change we can do if we want to allow incoming syslog
messages at all.

IMHO, we should encourage the system administrators to use this option,
and thus provide a knob in /etc/rc.* for it, defaulting to -a 127.0.0.1/32
(just as a hint about the usage).

Please state opinions about whether to merge this change into 2.2 or
not (i've got it running on RELENG_2_2 anyway).

Finally add the ability to syslogd to pipe particular messages through

97a86f545b Revert part of the previous change. syslogd (when logging to ttys)
has always held an open file descriptor.  This allowed logging to
spare virtual consoles and being able to switch to them.

My previous change removed this since all writes were done with ttymsg()
which opens it's own fd, and hence syslogd didn't need it's own fd to
send messages on... but this caused an unexpected behavior change.

This should close PR#2176

c21f06e391 put on my flame resistant suit and tempt fate by attempting to fix some of
the races in my previous commits here, and fix some other problems with
syslogd as well.

- if the child process exited early (eg: could not bind to the socket),
  the boot process would hang for 30 seconds.  The parent was not noticing
  that the child had exited.  (my fault)
- when writing to tty devices, instead of treating them like files that
  need \r\n instead of \n, actually use ttymsg() which has specific code
  intended to write to potentially blocking ttys safely.  I had a machine
  lock up last night because /dev/console on a serial port got flow control
  blocked.  Setting comcontrol drainwait fixed everything but syslogd which
  was going into a spin trying to write to the console and completely
  ignoreing everything else.
- fix a couple of nonsensical bits of code while here..  eg: wait3 takes
  a pointer to an int.  There is no sense in declaring it as 'union wait',
  then casting the pointer to (int *), then forgetting about it.

57a32f2a60 syslogd has always bugged me with it's async startup at boot time.
For me, more often than not, the backgrounded syslogd daemon is not
yet ready to process log messages before other things (such as named)
want to log a heap of them.  It seems that it's the O_SYNC writes of
the stuff coming in from /dev/klog that's the slowdown.

Anyway, instead of using the libc daemon, roll a modified version.  This
one has a timeout.  The child will wait for either the timeout to expire
or the child process to signal it to let it know that it's "ready" and
the /dev/log socket is set up and active, so it's safe to continue the
boot.  It adds a small fraction of a second pause to the boot time, but on
the other hand the overall boot time is *quicker* since the disk is not
being thrashed while the log messages are getting written out synchronously
one by one while other daemons are loading in parallel.

The timeout is in case the child segfaults or something before becoming
fully operational.

130177c924 With the recent 'make install' change in the kernel build makefiles, an
`interesting' feature of syslogd turned up.  It calls getbootfile() for each
log entry.  Since the kernel makefile now changes kern.bootfile when doing
a 'make install', it's quite startling to see the syslog lines change.

This change makes it call getbootfile() once at startup and cache it,
saving a syscall per loop, and keeping something a little more asthetically
pleasing in /var/log/messages...

75317367c5 Remove unconditional unlink at startup and conditionalised the unlink at exit
so that it only unlinks the file if syslogd knows it created it.

If the path specified for the socket already exists then syslogd
will now exit with an "address already in use" error which is more
sensible than blindly unlinking the existing filename.  This stops
syslogd -d foo/bar from unlinking foo/bar if it's a real file.
