tools: build qemu-vmsr-helper

2024-07-22T11:50:21Z

Introduce a privileged helper to access RAPL MSR. The privileged helper tool, qemu-vmsr-helper, is designed to provide virtual machines with the ability to read specific RAPL (Running Average Power Limit) MSRs without requiring CAP_SYS_RAWIO privileges or relying on external, out-of-tree patches. The helper tool leverages Unix permissions and SO_PEERCRED socket options to enforce access control, ensuring that only processes explicitly requesting read access via readmsr() from a valid Thread ID can access these MSRs. The list of RAPL MSRs that are allowed to be read by the helper tool is defined in rapl-msr-index.h. This list corresponds to the RAPL MSRs that will be supported in the next commit titled "Add support for RAPL MSRs in KVM/QEMU." The tool is intentionally designed to run on the Linux x86 platform. This initial implementation is tailored for Intel CPUs but can be extended to support AMD CPUs in the future.

qemu-img: add compression option to rebase subcommand

2023-10-31T12:51:28Z

If we rebase an image whose backing file has compressed clusters, we might end up wasting disk space since the copied clusters are now uncompressed. In order to have better control over this, let's add "--compress" option to the "qemu-img rebase" command. Note that this option affects only the clusters which are actually being copied from the original backing file. The clusters which were uncompressed in the target image will remain so.

9pfs: deprecate 'proxy' backend

2023-07-06T09:42:08Z

As recent CVE-2023-2861 (fixed by f6b0de53fb) once again showed, the 9p 'proxy' fs driver is in bad shape. Using the 'proxy' backend was already discouraged for safety reasons before and we recommended to use the 'local' backend (preferably in conjunction with its 'mapped' security model) instead, but now it is time to officially deprecate the 'proxy' backend.
