Bug 442238 – sys-apps/rng-tools-4 - /etc/init.d/rngd stop does not shutdown rngd with Ivy Bridge

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Chris Mayo 2012-11-07 19:43:48 UTC]

Reported upstream:
http://sourceforge.net/tracker/?func=detail&aid=3561711&group_id=3242&atid=103242

rng-tools-4 using Ivy Bridge (i3770) DRNG on Gentoo Linux, kernel gentoo-sources-3.5.2

- rngd running as daemon
1) killall rngd
- rngd still running
2) cat /dev/random > /dev/null
- rngd not running

rngd running in the foreground will stop immediately on SIGTERM
and can stop rngd daemon immediately with:
killall -s SIGALRM rngd




Workedaround for me by changing stop() line in init script to:

start-stop-daemon --signal ALRM --pidfile /var/run/rngd.pid

At a ThinkPad T420 (i5) rng-4-r1 fails to stop now too (unstable Gentoo user-mode-linux-image) :

 * Stopping hardware RNG daemon ...
 * start-stop-daemon: 1 process refused to stop
 [ !! ]
 * ERROR: rngd failed to stop

FWIW this helped :


start() {
        checkpath --directory /var/run/apache_ssl_mutex   <-------
        checkconfig || return 1

Confirmed here — got a fix for the init script as well.

And this is fixed in 4-r2. Thanks!
