Subject: munin-node: selinux_avcstats fails when /bin/sh is dash (bashism) Package: munin-node Version: 2.0.0-1~bpo60+1 Severity: normal
*** Please type your report below this line ***
Hello, today I upgraded from munin 1.4.5-3 (squeeze) to 2.0.0-1~bpo60+1
(squeeze-backports) and found the selinux_avcstats plugin to be broken.
Looks like the 1.4 version of the plugin used awk, and the 2.0 version replaces
use of awk with a couple shell 'read' builtins that don't work with dash.
Following is munin-node.log output:
2012/08/27-19:50:16 [17873] Error output from selinux_avcstat:
2012/08/27-19:50:16 [17873] read: 111: arg count
2012/08/27-19:50:16 [17873] /etc/munin/plugins/selinux_avcstat: 111:
Illegal number: lookups
2012/08/27-19:50:16 [17873] Service 'selinux_avcstat' exited with status 2/0.
Sorry, normally I'd try and write a patch, but this particular shell-fu is much
greater than mine (braces, read-while-read?!):
{ read
while read lookups hits misses allocations reclaims frees; do
LOOKUPS=$(($LOOKUPS + $lookups))
HITS=$(($HITS + $hits))
MISSES=$(($MISSES + $misses))
ALLOCATIONS=$(($ALLOCATIONS + $allocations))
RECLAIMS=$(($RECLAIMS + $reclaims))
FREES=$(($FREES + $frees))
done
} < $AVCSTATS
Kludgy work-around for me is replacing '#!/bin/sh' with '#!/bin/bash'.
BTW, thank you for backporting 2.0 to squeeze - my collection server is much
happier with new rrdcached backend :)
