[libvirt] Plan for next release
by Daniel Veillard 27 Oct '15

27 Oct '15

I'm a bit late, sorry, but I think we should freeze on Thursday for the next release, and then shoot for middle of next week for the actual release, I hope this last moment warning isn't a problem, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH] qemu: Resolve agent deadlock
by John Ferlan 27 Oct '15

27 Oct '15

If we have a shutdown of a VM by a qemu agent while an agent EOF occurs at relatively the same time, it's possible that a deadlock occurs depending on what happens first. Assume qemuProcessHandleAgentEOF runs first, with the vm->lock it clears priv->agent, then clears the vm->lock. After some agent call such as qemuDomainShutdownFlags will call qemuDomainObjExitAgent in a worker thread with the agent lock. It will then reference the priv->agent field: hasRefs = virObjectUnref(priv->agent); in order to determine whether there are references. However, since priv->agent is NULL, this returns false, so the subsquent: if (hasRefs) virObjectUnlock(priv->agent); will not unlock the agent. Eventually the EOF thread will attempt to call qemuAgentClose which will try to lock the agent, but cannot since it's still locked. This patch resolves this issue by keeping a copy of the priv->agent address prior to releasing the vm->lock in qemuDomainObjEnterAgent. Then rather than assuming priv->agent is valid, use the copy of the agent pointer for the subsequent agent call and qemuDomainObjExitAgent. Within qemuDomainObjExitAgent, use the agent copy in order to release the agent lock, then get the vm->lock again and decide whether to clear the priv->agent based on whether any references still exist.
