>Synopsis: syslogd !!prog fails to send multiple matches
>Category: BASE
>Environment:
System : OpenBSD 7.8
Details : OpenBSD 7.8-current (GENERIC.MP) #194: Wed Jan 7
23:50:10 MST 2026
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
When configuring syslogd to send a specific program to multiple
destinations,
only the first match sends receives the log.
>How-To-Repeat:
Configure syslog.conf with the following at the top of the file
!!program1
*.* /var/log/test1
*.* /var/log/test2
!*
... rest of syslog.conf
Make sure the log files exist
touch /var/log/{test1,test2}
Restart syslogd
rcctl restart syslogd
Now use the logger command to send a syslog message with program of
'program1'
logger -i -p daemon.info -t program1 "test"
Examining the test1 and test2 log files will show that only the test1
log
files has the log line in it.
>Fix:
The patch provided keeps track of the f_quick marking on the
destinations. If
the flag is set and the program/hostname is the same as the previous
log,
then the messaged is logged to the additional matching destination. If
the
next destination program/hostname doesn't match, the logging is
aborted. The
patch is against the current tree as of 2026-01-10.
