Description Olafur Osvaldsson 2004-07-21 18:10:13 UTC 
nsd is using SIGILL to determine if it should print out bind8 stats to the log.

This will not work if nsd is running as an unprivileged user.

Fix: SIGILL is not allowed for "tainted" processes so a non-restricted signal should be used.

I've contacted the developers and the patch attached is from them and will be included
in a future update.

The patch changes SIGILL to SIGUSR1.

	
How-To-Repeat: Make the port with WITH_BIND8_STATS, start as an unprivileged user and run
"kill -SIGILL `cat /var/run/nsd.pid`"
The prog will log the following to syslog:

nsd[66215]: problems killing 66219: Operation not permitted

66215 being the parent process and 66219 a child process.
