[libvirt] [PATCH v3 RESEND] qemu: Process RDMA GID state change event
by Yuval Shaia
This event is emitted on the monitor when a GID table in pvrdma device
is modified and the change needs to be propagate to the backend RDMA
device's GID table.
The control over the RDMA device's GID table is done by updating the
device's Ethernet function addresses.
Usually the first GID entry is determine by the MAC address, the second
by the first IPv6 address and the third by the IPv4 address. Other
entries can be added by adding more IP addresses. The opposite is the
same, i.e. whenever an address is removed, the corresponding GID entry
is removed.
The process is done by the network and RDMA stacks. Whenever an address
is added the ib_core driver is notified and calls the device driver's
add_gid function which in turn update the device.
To support this in pvrdma device we need to hook into the create_bind
and destroy_bind HW commands triggered by pvrdma driver in guest.
Whenever a changed is made to the pvrdma device's GID table a special
QMP messages is sent to be processed by libvirt to update the address of
the backend Ethernet device.

(fixing mail subject from v2 to v3, rest is the same)
Hi,
Corresponding qemu commit was merged to master as part of the following
patch-set:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg583387.html
Appreciate if this patch can be reviewed and merged as well.
Thanks,
Yuval
v1 -> v2:
* Address all comments from Michal Privoznik
v2 -> v3:
* Remove static initialization in processRdmaGidStatusChangedEvent

[libvirt] [PATCH v2 0/2] Makefile.am cleanups
by Eric Blake
Since v1:
- push patch 1, 2 that had successful reviews
- new patch 1
- rewrite old patch 3 to remove all use of gnulib from examples/,
rather than being partitioned based on what uses config.h (in part
by reverting Jan's recent patch that added config.h everywhere)

[libvirt] [dbus PATCH] util: fix virtDBusUtilDecodeUUID
by Pavel Hrdina
This function is supposed to convert ASCII character into its hex
representation, however the current implementation was wrong because
the first comparison would be false for all printable characters. In
most cases it worked but for example '$' which is 0x24 in HEX would be
incorrectly converted to 0x2[ which is obviously wrong.

[libvirt] [PATCH 0/3] Makefile.am cleanups
by Eric Blake
I noticed from IRC that Travis has been failing builds since our
Jan 1 update of gnulib. I'm not sure what changed in the gnulib
files to trip up clang, and I'm not really set up to test that
this fixes the problem seen by Travis (it works locally for me
using gcc - but gcc wasn't seeing the failure), but the ideas in
the patch make sense. So, unless there is an easy way to make
Travis run on candidate patches, I'll wait for a review rather
than pushing this as a build-breaker.

Essentially, bring back the old behaviour as of commit eba36a38 which
was later changed by commit ae06048bf5d. Even though all the stderr
messages will eventually end up in the journal, we're not making use of
the fields journald provides.

[libvirt] [PATCH 0/3] Rebase LXC network definition to support version 3.0
by Julio Faracco
The series propose a new way to define NICs inside LXC native. It is
needed because LXC version 3.X uses indexes to define NICs and the
current algorithm is not able to support them. At least, if you consider
settings defined using a random logic.
Julio Faracco (3):
lxc: refactoring LXC network definition with a sparse array.
tests: Change legacy network configs to version 3.0 with indexes.
tests: Include a random network testcase to test indexes.
