Description

The intention behind the funny bridge name was that it was impossible to create such a new via Engine. An evil customer could create a network named ovirt_vdsmdummy which would collide with vdsm's own dummy. Solving this bug is a bit of a headache. It requires a lot of attention to the upgrade path, in particular if the cluster has hosts with VMs that are still connected to ;vdsmdummy;. Regardless, other applications and tools should not assume that interface names do not include ';' or '&', and use proper quoting when needed. Robert, could you provide more details on the rkhunter result? Hi, we know that it would be the best if all applications would not assume common interface names, but there are some that do. We already fixed facter to work correctly. To prevent future hassle for us and others I opened the case to try to fix the root of the problem. I assume rhev has some detection to check whether a network collides with an existing interface. or where should this collision be a problem? rkhunter is a script that tries to detect suspicious files that could indicate rootkits. On what did you run the rkhunter script? Could you solve the apparent bug there with proper quoting? yes, the rkhunter script seems to work correctly now. But the the request was not to fix our immediate symptom, rather than removing the probable cause of further issues by using a normal name for the interface. Let us consider a nicer naming when dropping the Linux bridge in favor of OVS Closing old RFEs, please reopen if still needed. Patches are always welcomed. BZ<2>Jira Resync |
