[libvirt] [PATCH] qemu: fix argument of virDomainNetGetActualDirectMode
by ZhiPeng Lu
it should be a comparison of modes between new and old devices. So
the argument of the second virDomainNetGetActualDirectMode should be
newdev.

[libvirt] [PATCH v2] autogen.sh: Improve and generalize
by Andrea Bolognani
The goal is twofold: firstly, we want to extend the script so
that it can deal with more than a single git submodule, and
secondly we'd like to reduce the amount of duplicated code.
Moreover, since we're making heavy changes to the code anyway,
we might as well make sure it follows a somewhat consistent
coding style too.
To reduce code duplication, we introduce a new --dry-run
option, which can be used by third parties to figure out
whether calling autogen.sh is necessary or not: this allows
us to get rid of the reimplementation of part of the logic
in cfg.mk and guarantee they'll never get out of sync.
Other changes include: making dirty submodules checking and
cleaning entirely independent of other operations; removing
the use of 'set -e' and handling errors explicitly instead;
better parsing of command line arguments.
---
Changes from [v1]:
* drop the generic submodule update framework and simply
update all submodules unconditionally, *then* perform
any required gnulib-specific step;
* handle "autogen not required" and "dry run error"
differently in cfg.mk;
* improve comments.

[libvirt] [PATCH] test: Remove unnecessary unlocks in cleanup paths
by John Ferlan
Commit id '865f479da' altered the logic to use a common test*ObjFindByName
helpers which would lock/unlock the test driver; however, a few cleanup paths
in that cleanup missed removing the Unlock, so remove it now.

[libvirt] [PATCH] util: relax virNetDevSetCoalesce() stub
by Roman Bogorodskiy
Currently, virNetDevSetCoalesce() stub is always returning error. As
it's used by virNetDevTapCreateInBridgePort(), it essentially breaks
bridged networking if coalesce is not supported.
To make it work, relax the stub to trigger error only when its
coalesce argument is not NULL, otherwise report success.
