It's out ! The release is tagged in git, and I provided signed tarball and source rpms to the usual place: https://libvirt.org/sources/ I also cut off a 5.4.0 release of the python bindings but code is same a 5.3.0 one, you can find signed tarball and source rpms at: https://libvirt.org/sources/python/ Main theme of this release is security, there is a set of advisory covered so users are invited to update, along with some improvements and bug fixes. Security: - cpu: Introduce support for the md-clear CPUID bit This bit is set when microcode provides the mechanism to invoke a flush of various exploitable CPU buffers by invoking the x86 VERW instruction. CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091. - Restrict user access to virt-admin, virtlogd and virtlockd The intended users for these facilities are the root user and the libvirtd service respectively, but these restrictions were not enforced correctly. CVE-2019-10132. Improvements: - test driver: Expand API coverage Several APIs that were missing from the test driver have now been implemented. - Avoid unnecessary static linking Most binaries shipped as part of libvirt, for example virtlogd and libvirt_iohelper, were embedding parts of the library even though they also linked against the libvirt.so dynamic library. This is no longer the case, which results in both the disk and memory footprint being reduced. - qemu: Report stat-htlb-pgalloc and stat-htlb-pgfail balloon stats These stats have been introduced in QEMU 3.0. Bug fixes: - qemu: Fix emulator scheduler support Setting the scheduler for QEMU's main thread before QEMU had a chance to start up other threads was misleading as it would affect other threads (vCPU and I/O) as well. In some particular situations this could also lead to an error when the thread for vCPU #0 was being moved to its cpu,cpuacct cgroup. This was fixed so that the scheduler for the main thread is set after QEMU starts. - apparmor: Allow hotplug of vhost-scsi devices Thanks everybody who contributed to this release, be it with bug reports, patches, reviews, docs ...
