[libvirt] [PATCH v4 00/10] Add user namespace support for libvirt lxc
by Gao feng
This patchset try to add userns support for libvirt lxc.
Since userns is nearly completed in linux-3.9, the old
kernel doesn't support userns, I add some New XML elements
to let people decide if enable userns.The userns is enabled
only when user configure the XML.
The format of user namespace related XML file like below:
<idmap>
<uid start='0' target='1000' count='10'>
<gid start='0' target='1000' count='10'>
</idmap>
it means the user in container (which uid:gid is 0:0) will
be mapped to the user in host (uid:gid is 1000:1000), count
is used to form an u/gid range: The users in container which
uid in [start, start + count -1] will be mapped.
You can have multiple lines to map differnet id ranges,
caution, you must make sure the root user of container has
been mapped.
This patchset also does the below jobs.
1, Because the uninit userns has no right to create devices,
we should create devices for container on host.
2, Changes the owner of fuse and tty device.
Change from v3:
1, fix some bugs that Daniel pointed out
2, reorder the patchset,introduce virLXCControllerChown first.
3, rebase
Change from v2:
1, Mount tmpfs on /stateDir/domain.dev
2, Create devices under /stateDir/doamin.dev/
3, Mount Move the /.oldroot/stateDir/doamin.dev/ on the /dev/ of container
4, Enhance the configuration, disallow the semi configuration
Gao feng (10):
LXC: Introduce New XML element for user namespace
LXC: enable user namespace only when user set the uidmap
LXC: sort the uidmap/gidmap of domain
LXC: introduce virLXCControllerSetupUserns and lxcContainerSetID
LXC: Creating devices for container on host side
LXC: controller: change the owner of tty devices to the root user of
container
LXC: controller: change the owner of /dev to the root user of
container
LXC: controller: change the owner of devices created on host
LXC: controller: change the owner of /dev/pts and ptmx to the root of
container
LXC: fuse: Change files owner to the root user of container

[libvirt] [PATCH] Ignore failure to mount SELinux filesystem in container
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
User namespaces will deny the ability to mount the SELinux
filesystem. This is harmless for libvirt's LXC needs, so the
error can be ignored.

[libvirt] [PATCH] build: configure must not affect tarball contents
by Eric Blake
On mingw, configure sets the name of the lxc symfile to
libvirt_lxc.defs rather than libvirt_lxc.syms. But tarballs
must be arch-independent, regardless of the configure options
used for the tree where we ran 'make dist'. This led to the
following failure in autobuild.sh:
CCLD libvirt-lxc.la
CCLD libvirt-qemu.la
/usr/lib64/gcc/i686-w64-mingw32/4.7.2/../../../../i686-w64-mingw32/bin/ld: cannot find libvirt_lxc.def: No such file or directory
collect2: error: ld returned 1 exit status
make[3]: *** [libvirt-lxc.la] Error 1
make[3]: *** Waiting for unfinished jobs....
We were already doing the right thing with libvirt_qemu.syms.

depends on configure for its final name.

[libvirt] [PATCH] build: avoid build failure without gnutls

Found while trying to cross-compile to mingw:

../../src/remote/remote_driver.c:487:23: error: variable 'verify' set but not used [-Werror=unused-but-set-variable]
* src/remote/remote_driver.c (doRemoteOpen): Also ignore 'verify'.

---
Pushing under the build-breaker rule.
I also had a report that libvirt fails to compile for mingw on
Fedora 19; it looks like a gnulib submodule update will fix
part of that issue, so I'm working on that now...

[libvirt] [PATCH] Drop iptablesContext
by Roman Bogorodskiy
iptablesContext holds only 4 pairs of iptables
(table, chain) and there's no need to pass
it around.
This is a first step towards separating bridge_driver.c
in platform-specific parts.
