[libvirt] [PATCH 0/2] Fix another possible memory leak in nwfilter
by John Ferlan
Oh lucky me - why am I stuck in nwfilter land....
The first patch just cleans up the code and the second one resolves the
memory leak problem as well as a general error path problem.
Coverity noted that the error path wasn't checked - this is because
other recent changes in the module caused Coverity to decide to rethink
about this one noticing the lack of an error check. Of course upon more
visual inspection, the memory leak was obvious too.

[libvirt] [PATCH go-xml] qemu: extend serial console source
by Jeroen Simonetti
*Warning* this is a BWC breaking change!
This will change the type of `DomainSerial.Source` from
`*DomainChardevSource` to a new `*DomainSerialSource`.
This is done to add support for networked serial ports and
keep the original DomainChardevSource unchanged.
DomainSerialSource contains all possible xml variations
for a serial device source.

[libvirt] [PATCH v2 0/2] Clean up the nwfilter mess I created
by John Ferlan
v1: https://www.redhat.com/archives/libvir-list/2017-September/msg01072.html
Changes:
* Patch1: No change, ACK'd, but not safe to push yet either..
* Patch2: Rather than have virNWFilterIPAddrMapAddIPAddr consume
the input @addr, let's make a copy of the input parameter
and manage it within that code so that it wouldn't be
consumed on virNWFilterHashTablePut failure after
virNWFilterVarValueCreateSimple success.
John Ferlan (2):
Revert "nwfilter: Fix possible segfault on sometimes consumed
variable"
nwfilter: Don't have virNWFilterIPAddrMapAddIPAddr consume input
