[Libvirt-announce] Entering freeze for libvirt-1.2.2
by Daniel Veillard 26 Feb '14

26 Feb '14

As planned I tagged a release candidate 1 version in git and made tarballs and rpms available at the usual place: ftp://libvirt.org/libvirt/ it seems to work well in my limited testing, but let's spend some time this week making more tests and checking it compiles on other systems and architectures. if all goes well I will probably push the release next week-end, with an rc2 on Wednesday based on feedback, thanks !

[Libvirt-announce] ANNOUNCE: libvirt-glib release 0.1.8
by Daniel P. Berrange 21 Feb '14

21 Feb '14

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.8, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) Changes in this release: - Add getter/setter for UUID in domain config - Remove dead code / unused variables - Add missing symbol exports - Add support for setting nwfilters in domain config - Switch to standard gobject introspection autotools macros - Fix typo preventing removal of clock config - Add getter/setters for disk driver type - Add unit tests based on glib tap harness - Add test for validating symbol file exports - Add getters for domain graphics config params - Add more getters for domain timer config - Add support for hpet timer type - Fix event loop impl on win32 - Fix parent class/object of pit timer class - Fix misc API doc bugs - Add more getters for domain clock config - Fix removal of domain CPU feature flags - Fix removal of capabilities CPU topology - Misc fixes to glib event loop integration libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[Libvirt-announce] LSN-2013-0018: Unsafe usage of paths under /proc/$PID/root by the LXC driver
by Daniel P. Berrange 19 Feb '14

19 Feb '14

Libvirt Security Notice: LSN-2013-0018 ====================================== Summary: Unsafe usage of paths under /proc/$PID/root by the LXC driver Reported on: 20131217 Published on: 20131217 Fixed on: 20140219 Reported by: Reco <recoverym4n(a)gmail.com> Patched by: Reco <recoverym4n(a)gmail.com>, Eric Blake <eblake(a)redhat.com>, Daniel Berrange <berrange(a)redhat.com> See also: CVE-2013-6456, debian bug #732394 Description ----------- The LXC driver will open paths under /proc/$PID/root for some operations it performs on running guests. For the virDomainShutdown and virDomainReboot APIs it will use this to access the /dev/initctl path in the container. For the virDomainDeviceAttach / virDomainDeviceDettach APIs it will use this to create device nodes in the container's /dev filesystem. If any of the path components under control of the container are symlinks the container can cause the libvirtd daemon to access the incorrect files. Impact ------ A container can cause the administrator to shutdown or reboot the host OS if /dev/initctl in the container is made to be an absolute symlink back to itself or /run/initctl. A container can cause the host administrator to mknod in an arbitrary host directory when invoking the virDomainDeviceAttach API by replacing '/dev' with an absolute symlink. A container can cause the host administrator to delete host device when invoking the virDomainDeviceDettach API by replacing '/dev' with an absolute symlink. Workaround ---------- Do not use the virDomainShutdown or virDomainReboot APIs without also passing the VIR_DOMAIN_SHUTDOWN_SIGNAL or VIR_DOMAIN_REBOOT_SIGNAL flags respectively. These will cause the LXC driver to send a SIGTERM or SIGHUP signal respectively, to the init process instead of using /dev/initct.. Do not use the virDomainDeviceAttach or virDomainDeviceDetach APIs at all unless the guest OS is trusted.
