taca 6e662bb75d Put pidfile after daemonize. This would fix newsyslog(8) error. 2001-07-19 00:15:32 +00:00
manu 764096179a - No more lost error messages during syslogd startup, they now all appear on
stdout before syslogd becomes a daemon.
- Flags for setuid/setgid/chroot syslogd after initialization is completed
- Warning instead of silent ignoring for malformed lines (with spaces instead
of tags)

jwise ea7e9f5176 Fix minor thinko in previous. Make sure we close and keep closed all
sockets in the situation where all of the following are true:

	* /etc/syslogd.conf contained forwarding actions when we were
	  started up or when we last received a HUP

	* /etc/syslogd.conf has had all forwarding actions removed

	* we are running with -s

and we receive a HUP.

jwise 20abf1785a Back out and redo previous at Bill Sommerfeld's <sommerfeld@netbsd.org>
request:

	instead of the -S flag, fix the -s flag to not open a socket
	if there are no forwarding rules in /etc/syslog.conf

The behavior of syslogd when -s is specified and there are forwarding rules
should still be made cleaner.
2000-06-30 18:03:50 +00:00
jwise 3258a51b03 1.) bring usage text up to date, and clarify description of `-s' option
in man page and comments -- for some time it has no longer prevents
    an inet socket from being opened, just caused it to be ignored

2.) Fix this problem with `-s' -- syslogd always opens an inet socket, even if
    -s is specified and it has nowhere to send to.  This socket is then
    shutdown(), but there is no way to not have this socket open.

    Users setting up paranoid installations can now specify `-S' which
    prevents any non-unix-domain sockets from being opened, even if
    forwarding is specified in /etc/syslogd.conf.

    As per the previous fix, this is not made the default for `-s', as it
    also prevents syslogd from forwarding log messages.

3.) document the above in the man page and usage.

Justification:  in light of the possibility of future DoS attacks, or the
desire to set up a machine which is relatively uninformative in the face
of port scans, users may quite legitimately want to control what sockets
are open on their machine.  Telling such users that they cannot run
syslogd is non-ideal.

lukem 315a29d6de * in secure mode (-s), still open the inet sockets but do a shutdown(,SHUT_RD)
on each of them, and don't bother listening on them. this allows messages
  to be forwarded even with -s enabled.

  XXX: not 100% sure if this is susceptable to a DoS, e.g someone filling
  up kernel buffers with a backlog of packets not being read, but shutdown(2)
  should prevent that even if it possibly doesn't at this time.

mrg 19ef5d758f - allow -p /log/socket to appear more than once (and work as expected
if given this).  this is extremely useful for chrooted daemons that
  still want to create log entries via a local mechanism.

- create a new -P option that takes a filename of log sockets (equiv.
  of calling syslogd which -p <each line of file>.  this is useful
  for the case of many chroot areas and keeping this information in
  one place rather than having to remember it all.

if no -p options are given, the default (_PATH_LOG) is used as normal.
