Re: [libvirt] [PATCH] audit: properly encode device path in cgroup audit

https://bugzilla.redhat.com/show_bug.cgi?id=922186 Commit d04916fa introduced a regression in audit quality - even though the code was computing the proper escaped name for a path, it wasn't feeding that escaped name on to the audit message. As a result, /var/log/audit/audit.log would mention a field path=/dev/hpet instead of the intended path="/dev/hpet", which in turn caused ausearch to format the audit log as path=(null). * src/conf/domain_audit.c (virDomainAuditCgroupPath): Use constructed encoding.
