Description Attila Fazekas 2015-01-22 09:46:28 UTC 
Description of problem:

The ebtables command cannot be used without unexpected issues when you issue it without --concurrent option in parallel.

firewalld should not ever issue an ebtables command without acquiring the ebtables lock or using --concurrent option.

The the lock is required to play nicely with other ebtables users (for Ex.: openstack-nova).

Version-Release number of selected component (if applicable):
firewalld-0.3.13-1.fc21

Actual results:
The ebtables commands usual output without locking:

Unable to update the kernel. Two possible causes:
1. Multiple ebtables programs were executing simultaneously. The ebtables
   userspace tool doesn't by default support multiple ebtables programs running
   concurrently. The ebtables option --concurrent or a tool like flock can be
   used to support concurrent scripts that update the ebtables kernel tables.
2. The kernel doesn't support a certain ebtables extension, consider
   recompiling your kernel or insmod the extension.
