Re: audit.63 kernel.



[resend without word wrap]

with 2.6.9-11.EL.audit.63smp and audit-0.9.10-1 this script causes a
repeatable oops:

#!/bin/bash -x

FILE_NAME=`mktemp /tmp/test_append.XXXXXX`

auditctl -w ${FILE_NAME} -k fk_test_append_r -p r
auditctl -w ${FILE_NAME} -k fk_test_append_w -p w
auditctl -w ${FILE_NAME} -k fk_test_append_x -p x

echo "test" >> ${FILE_NAME}
