[PATCH] qemu_process: Release domain seclabel later in qemuProcessStop()
by Michal Privoznik 06 Jan '21

06 Jan '21

Some secdrivers (typically SELinux driver) generate unique dynamic seclabel for each domain (unless a static one is requested in domain XML). This is achieved by calling qemuSecurityGenLabel() from qemuProcessPrepareDomain() which allocates unique seclabel and stores it in domain def->seclabels. The counterpart is qemuSecurityReleaseLabel() which releases the label and removes it from def->seclabels. Problem is, that with current code the qemuProcessStop() may still want to use the seclabel after it was released, e.g. when it wants to restore the label of a disk mirror. What is happening now, is that in qemuProcessStop() the qemuSecurityReleaseLabel() is called, which removes the SELinux seclabel from def->seclabels, yada yada yada and eventually qemuSecurityRestoreImageLabel() is called. This bubbles down to virSecuritySELinuxRestoreImageLabelSingle() which find no SELinux seclabel (using virDomainDefGetSecurityLabelDef()) and this returns early doing nothing.

[PATCH 1/7] conf: Add NFS disk protocol
by Ryan Gahagan 06 Jan '21

06 Jan '21

Per Issue 90, Libvirt does not support attaching an NFS disk even though QEMU has added support for it. This series of patches seeks to implement this support in Libvirt and begins by adding in flags for an NFS disk.

[PATCH RFC v4 00/15] Add riscv kvm accel support
by Yifei Jiang 05 Jan '21

05 Jan '21

This series adds both riscv32 and riscv64 kvm support, and implements migration based on riscv. It is based on temporarily unaccepted kvm: https://github.com/kvm-riscv/linux (lastest version v15). This series depends on above pending changes which haven't yet been accepted, so this QEMU patch series is treated as RFC patches until that dependency has been dealt with. Compared to RFC v3, the time scaling is supported in this series. The new feature also requires the following patches: [1] Bugfix in kvm v15 https://lkml.org/lkml/2020/11/30/245 [2] kvm patches: [PATCH RFC 0/3] Implement guest time scaling in RISC-V KVM Several steps to use this: 1.

[PATCH 00/10] Fix NSS plugin and net-dhcp-get-leases wrt to infinite leases
by Michal Privoznik 05 Jan '21

05 Jan '21

Some things are broken when using leases that don't expire. We don't store "expiry-time" in corresponding $brname.status file which sets off a spiral and we get errors from other places which expect it to be there always. These patches make sure that the attribute is always there. I've also implemented another approach, which puts "expiry-time" into the file only if not infinite and fixed the other places which expect it: https://gitlab.com/MichalPrivoznik/libvirt/-/commits/leases_docs/ but I like this version more.
