[PATCH] qemuProcessSetupRawIO: Refactor return value and remove useless #ifdef
by Peter Krempa 03 Sep '24

03 Sep '24

The function can return directly rather than setting 'ret' as there's no cleanup. It also doesn't make sense to conditionally compile out the 'break' statement when checking whether a disk has rawio enabled if 'CAP_SYS_RAWIO' is _not_ defined as the function will still behave the same.

[libvirt][PATCH] qemu_nbdkit.c: use %llu to print time_t

Release of libvirt-10.7.0
by Jiri Denemark 02 Sep '24

02 Sep '24

The 10.7.0 release of both libvirt and libvirt-python is tagged and signed tarballs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * Security * CVE-2024-8235: Crash of ``virtinterfaced`` via ``virConnectListInterfaces()`` A refactor of the code fetching the list of interfaces for multiple APIs introduced corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of ``virtinterfaced`` if ``virConnectListInterfaces()`` is called requesting 0 networks to be filled. The bug was introduced in libvirt-10.4.0 * New features * qemu: Introduce the ability to disable the built-in PS/2 controller It is now possible to control the state of the ``ps2`` feature in the domain XML for descendants of the generic PC machine type (``i440fx``, ``q35``, ``xenfv`` and ``isapc``). * Improvements * ch: support restore with network devices Cloud-Hypervisor starting from V40.0 supports restoring file descriptor backed network devices. So, create new net fds and pass them via SCM_RIGHTS to CH during restore operation. * ch: support basic networking modes Cloud-Hypervisor driver now supports Ethernet, Network (NAT) and Bridge networking modes. Enjoy. Jirka

Changing permissions for /var/lib/libvirt/images/
by Lee Garrett 02 Sep '24

02 Sep '24

Hi everyone, while using virt-v2v I've hit an issue [0], where essentially virt-v2v fails as non-root user, due to /var/lib/libvirt/images/ belonging to root:root. I proposed to change the ownership to root:libvirt, and permission bits to ug=rwx,o=x, as that would allow users of the libvirt group to use virt-v2v without running as root. My questions here are: Are there any downsides to this? AFAICS users of the libvirt group are allowed changed images via the libvirt API anyway, so from the security standpoint there should be no change. And if there are none, can we change the upstream default to those permissions? Thanks in advance, Lee P.S.: Keep me CCed, I'm off-list. [0] downstream Debian bug with more details: https://bugs.debian.org/1054230

PRO: compatible extension; no management application updates needed unless they want to support sub-second delays. CON: specifying a sub-second delay takes two parameters, which is awkward. CON: trap in combination with -set. Before the patch, something like -set chardev.ID.reconnect=N means N seconds no matter what. Afterwards, it depends on the value of reconnect-is-ms, which may be set far away. Mitigating factor: -set is obscure. Alternatives: 1. Change @reconnect to 'number', specify sub-second delays as fractions. PRO: compatible extension; no management application updates needed unless they want to support sub-second delays. CON: first use of floating-point for time in seconds in QAPI, as far as I can see. CON: QemuOpts can't do floating-point. 2. Deprecate @reconnect in favour of a new member with a more suitable unit. Error if both are present. PRO: after @reconnect is gone, the interface is what it arguably should've been from the start. CON: incompatible change. Management application updates needed within the deprecation grace period. Let's get additional input from management application developers. I cc'ed some.
