[libvirt PATCH] bhyve: utils: use relative path for virclosecallbacks.h
by Ján Tomko 25 Feb '20

25 Feb '20

When moving virclosecallbacks to src/hypervisor, I did not adjust all the possible includes in Makefiles. Use a path relative to src to fix the build.

[PATCH 0/3] Tighten qemu-img rules on missing backing format
by Eric Blake 25 Feb '20

25 Feb '20

In the past, we have had CVEs caused by qemu probing one image type when an image started out as another but the guest was able to modify content. The solution to those CVEs was to encode backing format information into qcow2, to ensure that once we make a decision, we don't have to probe any further. However, we failed to enforce this at the time. And now that libvirt is switching to -blockdev, it has come back to bite us: with -block, libvirt had no easy way (other than json:{} pseudoprotocol) to force a backing file, but with -blockdev, libvirt HAS to use blockdev-open on the backing chain and supply a backing format there, and thus has to probe images. If libvirt ever probes differently than qemu, we are back to the potential guest-visible data corruption or potential host CVEs. It's time to deprecate images without backing formats. This patch series does two things: 1. record an implicit backing format where one is learned (although sadly, not all qemu-img commands are able to learn a format), 2. warn to the user any time a probe had ambiguous results or a backing format is omitted from an image. All previous images without a backing format are still usable, but hopefully the warnings (along with libvirt's complaints about images without a backing format) help us pinpoint remaining applications that are creating images on their own without recording a backing format. Perhaps I need to amend patch 3 and/or add a followup patch 4 that adds further iotest coverage of all the new warnings (patch 1 touched all the './check -qcow2' tests that were affected by the new warnings, except for 114 which actually wanted to trigger the warning, if you want to apply the series out of order to see the impact of the warnings).

[libvirt PATCH] ci: Fix handling of $PKG_CONFIG_LIBDIR
by Andrea Bolognani 24 Feb '20

24 Feb '20

There are two environment variables that are baked into our cross-compilation container images at build time, $CONFIGURE_OPTS and $PKG_CONFIG_LIBDIR: the former contain the options necessary to convince configure to perform a cross build rather than a native one, and the latter is necessary so that pkg-config will locate the .pc files for MinGW libraries. Container images that are not intended for cross-compilation will not have either one defined. The problem is that, while an empty $CONFIGURE_OPTS is completely harmless, setting $PKG_CONFIG_LIBDIR to an emtpy value will result in pkg-config not looking in its default search path, thus not finding any library, and subsequently breaking native builds. To work around this issue, only pass $PKG_CONFIG_LIBDIR to sudo when the value is set in the calling environment.

[PATCH] apparmor: allow to call vhost-user-gpu
by Christian Ehrhardt 24 Feb '20

24 Feb '20

Configuring vhost-user-gpu like: <video> <driver name='vhostuser'/> <model type='virtio' heads='1'/> </video> Triggers an apparmor denial like: apparmor="DENIED" operation="exec" profile="libvirtd" name="/usr/lib/qemu/vhost-user-gpu" pid=888257 comm="libvirtd" requested_mask="x" denied_mask="x" fsuid=0 ouid=0 This helper is provided by qemu for vhost-user-gpu and thereby being in the same path as qemu_bridge_helper. Due to that adding a rule allowing to call uses the same path list.
