| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms

| | | | | | | each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len). This works now that kernel fd passing has been fixed to accept a bit of sloppiness because of this ABI repair. lots of discussion with kettenis

* Create "syslogd: restart" message after the setup of signalmpf2007-02-211-6/+9

* implement logging to other program's stdin.henning2007-02-202-17/+139
| | | | | | | | | | if the target is like "| /path/to/program", syslogd forks and execs program and sends the selected log messages to program's stdin. uses a socketpair, grows the receive buffer on the reader side and has the socket nonblocking on syslog'd side to prevent syslogd blocking. I'm using that here to feed logsurfer from ports for automated log analysis, werks beautifully. lots of input & help mpf, ok mpf djm "no objections" millert

| | | | | | | SA_NOCLDSTOP flag for the SIGCHLD handler so the kernel does not notify us when the child has been stopped, only when it exits. Fixes a problem where if you suspended the child process the parent would exit. OK otto@

* Fix one case of broken duplicate supression, which happens if two linesotto2004-12-201-18/+58
| | | | | | | | | | | | | | in syslog.conf contain the same target file, and log entries matching both the first and second line get written. This changes behaviour: e.g. previously repeating a line caused a log entry to be written twice, but not any more. Also, if a later line with the same target has a different priority for a facility, the last one will be used. Noted by camield@; help from millert@. ok camield@ millert@ hshoexer@ deraadt@
