CVS commit: [thorpej-syslogd-hack-branch] src/usr.sbin/syslogd

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Thu Nov 18 16:11:04 UTC 2004

Modified Files:
        src/usr.sbin/syslogd [thorpej-syslogd-hack-branch]: syslogd.c

Log Message:
Fix a race condition between syslogd and logging sub-processes:

When sending a message to a pipe, if the command exits after e.g. a single
line of input, we might try to send it another message line before we get
the SIGCHLD event and reap the sub-process, meaning that we'll have stale
state and get an EPIPE.

So, if we get an EPIPE, attempt to re-open the pipe and send the message
line again.
