From d530e342320d4db3c9522bfadc60a7bc8142343a Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 14 May 2014 15:12:34 +0200 Subject: qemu-iotests: Fix core dump suppression in test 039 The shell script attempts to suppress core dumps like this: old_ulimit=$(ulimit -c) ulimit -c 0 $QEMU_IO arg... ulimit -c "$old_ulimit" This breaks the test hard unless the limit was zero to begin with! ulimit sets both hard and soft limit by default, and (re-)raising the hard limit requires privileges. Broken since it was added in commit dc68afe. Could be fixed by adding -S to set only the soft limit, but I'm not sure how portable that is in practice. Simply do it in a subshell instead, like this: (ulimit -c 0; exec $QEMU_IO arg...)
