[libvirt] Libvirt Security Notices
by Daniel P. Berrange 17 Jan '14

17 Jan '14

Hi Folks, After much work I've finally got a formal Libvirt Security Notice (LSN) setup worked out. Every security issue that is reported & confirmed on the libvirt security mailing list will have a formal LSN prepared. This is a simple XML document containing metadata & other information about the issue we deem relevant. Initially this will be private if there is an embargo applied. Once the issue is made public, will the LSN notices will be added to the following public GIT repository: http://libvirt.org/git/?p=libvirt-security-notice.git;a=summary This GIT repository is used to populate a new public website http://security.libvirt.org/ A plain text rendering of the LSN will also be sent to the mailing list libvirt-announce(a)redhat.com Every issue is available in text, html and xml formats eg http://security.libvirt.org/2014/0002.txt http://security.libvirt.org/2014/0002.html http://security.libvirt.org/2014/0002.xml If anyone backports a fix for a security issue to various -maint branches, the LSN notice in GIT should be updated with GIT hash of the backports. If a maint release is created, the tag should also be added to the LSN. After countless hours investigation I have populated the repository with a list of all historical issues in libvirt that I'm aware of.

[libvirt] Add GVirConfigDomainDiskDriver
by Christophe Fergeau 17 Jan '14

17 Jan '14

Hey, I wanted to add support in libvirt-gconfig for the 'discard' attribute of the disk driver node. If I follow the way the API is currently done, it would be an additional method to GVirConfigDomainDisk. However, there are quite a few attributes attached to the disk driver node, so I felt it was preferrable to have a dedicated GVirConfigDomainDiskDriver class. This also matches better other places of libvirt-gconfig API. I've implemented support for most of the attributes of the disk driver node, as a result the corresponding methods in GVirConfigDomainDisk have been deprecated. Christophe

[libvirt] [PATCH] virSecuritySELinuxSetFileconHelper: Don't fail on read-only NFS
by Michal Privoznik 17 Jan '14

17 Jan '14

https://bugzilla.redhat.com/show_bug.cgi?id=996543 When starting up a domain, the SELinux labeling is done depending on current configuration. If the labeling fails we check for possible causes, as not all labeling failures are fatal. For example, if the labeled file is on NFS which lacks SELinux support, the file can still be readable to qemu process. These cases are distinguished by the errno code: NFS without SELinux support returns EOPNOTSUPP. However, we were missing one scenario. In case there's a read-only disk on a read-only NFS (and possibly any FS) and the labeling is just optional (not explicitly requested in the XML) there's no need to make the labeling error fatal. In other words, read-only file on read-only NFS can fail to be labeled, but be readable at the same time.

[libvirt] On Archbsd which uses Freebsd10 kernel and world the libvirt-glib with enable-introspection does not compile (using gcc or clang)
by Claudiu Traistaru 17 Jan '14

I have already posted a bug request about this. https://bugzilla.redhat.com/show_bug.cgi?id=1054657 The issue appears when trying to build with --enable-introspections flag. I think it would be super if somebody had a solution for this, because virt-manager is an nice tool to have.
