[PATCH] spec: Restart libvirtd on upgrade without socket activation
by Martin Kletzander
The %posttrans phase needs has a special case for upgrading libvirt
daemon with --listen, but it forgot to also restart the daemon in order
to run the new installed version.

[libvirt PATCH 0/9] src: misc cleanups related to remote protocol/client
by Daniel P. Berrangé
Just before xmas I did some work on an rpcgen replacement so
we can use a non-sucky API instead of xdr_*. This short series
has some general cleanups I found useful. The rpcgen code will
come later.
While this is all non-functional changes, I'm NOT proposing
it for 9.0, it can safely wait as it isn't fixing any real
bugs (that I've realized).
Daniel P. Berrangé (9):
remote: remove redundant initialization of args variable
lxc: fix XDR protocol compliance
logging: remove redundant XDR typedef
rpc: use VIR_LOCK_GUARD in remote client code
remote: use VIR_LOCK_GUARD in client code
admin: use VIR_LOCK_GUARD in client code
rpc: use struct zero initializer instead of memset
remote: use struct zero initializer instead of memset
admin: use struct zero initializer instead of memset

[PATCH] qemu: Fix handling of passed FDs in remoteDispatchDomainFdAssociate
by Peter Krempa
To ensure same behaviour when remote driver is or is not used we must
not steal the FDs and array holding them passed to qemuDomainFDAssociate
but rather duplicate them. At the same time the remote driver must close
and free them to prevent leak.
Pointed out by Coverity as FD leak on error path:
*** CID 404348: Resource leaks (RESOURCE_LEAK)
/src/remote/remote_daemon_dispatch.c: 7484 in remoteDispatchDomainFdAssociate()
7478 rv = 0;
7479
7480 cleanup:
7481 if (rv < 0)
7482 virNetMessageSaveError(rerr);
7483 virObjectUnref(dom);
>>> CID 404348: Resource leaks (RESOURCE_LEAK)
>>> Variable "fds" going out of scope leaks the storage it points to.

[PATCH 00/12] migration/migrationpin:support migration pin
by Jiang Jiacheng
Support set the CPU affinity of the live migration thread to improve
the migration performance in specific cases. By default, the migration
thread shares CPU resources with the VM process. With those API, support
pin migration thread to expected CPU list to avoid preempting CPU
resources of VM process.
New API 'pinMigrationThread' and virsh command 'virsh migrationpin'
is used to pin migration thread to expected CPU list before or during
migration.
New migration param 'migration.pin' is used to support migration pin
via interface 'virDomainMigrateToURI3'.

[PATCH] conf: check vhost-user queues with vcpus
by Jiang Jiacheng
With kernel without the ref patch, if queues > vcpus, interrupts
will be centralized on one vcpu affecting guest performance. After
the ref patch merged, the queues whose number is greater than the
number of vcpus will not be used.
Considering the above, it's better to check the counts of vhost-user
queues and vcpus.

[PATCH] remote: fix double free of migration params on error
by Daniel P. Berrangé
The remote_*_args methods will generally borrow pointers
passed in the caller, so should not be freed.
On failure of the virTypedParamsSerialize method, however,
xdr_free was being called. This is presumably because it
was thought that the params may have been partially
serialized and need cleaning up. This is incorrect, as
virTypedParamsSerialize takes care to cleanup partially
serialized data. This xdr_free call would lead to free'ing
the borrowed cookie pointers, which would be a double free.
