[libvirt PATCH] qemu_firmware: select correct firmware for AMD SEV-ES
by Pavel Hrdina 14 Jun '21

14 Jun '21

When using firmware auto-selection and user enables AMD SEV-ES we need to pick correct firmware that actually supports it. This can be detected by having `amd-sev-es` in the firmware JSON description.

[libvirt PATCH v2 0/7] Enable sanitizers
by Tim Wiederhake 14 Jun '21

14 Jun '21

This series enables and adds AddressSanitizer and UndefinedBehaviorSanitizer builds to the CI. See: https://clang.llvm.org/docs/AddressSanitizer.html and https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html These sanitizers already found some issues in libvirt, e.g. 4eb7c621985dad4de911ec394ac628bd1a5b29ab, 1294de209cee6643511265c7e2d4283c047cf652, 8b8c91f487592c6c067847ca59dde405ca17573f, or 1c34211c22de28127a509edbf2cf2f44cb0d891e. There exist two more relevant sanitizers, ThreadSanitizer and MemorySanitizer. Unfortunately, those two require an instrumented build of all dependencies, including libc, to work correctly. Note that clang and gcc have different implementations of these sanitizers, hence the introduction of two new jobs to the CI. The latter one issues a warning about the use of LD_PRELOAD in `virTestMain`, which in this particular case can be safely ignored by setting `ASAN_OPTIONS` to verify_asan_link_order=0` for the gcc build. Changes since V1: Incorporated changes suggested by Pavel, except for #6 (now #7): The statement in https://listman.redhat.com/archives/libvir-list/2021-May/msg00070.html on the sanitizers working with Fedora 33 is wrong, I was fooled by caching. The bug described there is present in Fedora 33, 34, and Rawhide. Cheers, Tim Tim Wiederhake (7): meson: Allow larger stack frames when instrumenting meson: Allow undefined symbols when sanitizers are enabled tests: virfilemock: realpath: Allow non-null second parameter openvz: Add missing symbols to libvirt_openvz.syms tests: openvzutilstest: Remove duplicate linking with libvirt_openvz.a virt-aa-helper: Remove duplicate linking with src/datatypes.o ci: Enable address and undefined behavior sanitizers .gitlab-ci.yml | 35 +++++++++++++++++++++++++++++++++++ build-aux/syntax-check.mk | 2 +- meson.build | 14 ++++++++++---- src/libvirt_openvz.syms | 2 ++ src/security/meson.build | 1 - tests/meson.build | 2 +- tests/virfilemock.c | 20 ++++++++++++-------- 7 files changed, 61 insertions(+), 15 deletions(-) -- 2.26.3

[libvirt PATCH v2 0/7] Enable autostarting mediated devices
by Jonathon Jongsma 10 Jun '21

10 Jun '21

This series replaces the initial patch that was recently reverted. It implements the autostart feature using a new virNodeDeviceGet/SetAutostart() API that is consistent with how other libvirt objects handle autostart. It also adds a counterpart virsh command nodedev-autostart. In order to easily check the 'autostart' status of the device (since it is no longer part of the device xml), a new virsh command is introduced: nodedev-info. This also presents a few more basic bits of information about the device, including 'active' and 'persistent' status, which requires exposing new APIs on the node device: IsActive() and IsPersistent(). These APIs are consistent with existing libvirt objects. Changes in version 2: - Parse the autostart property from mdevctl output. - only re-sending patch 2/7, all others were already ACKED Jonathon Jongsma (7): api: add virNodeDevice(Get|Set)Autostart() nodedev: implement virNodeDevice(Get|Set)Autostart() nodedev: Add tests for mdevctl autostart command virsh: add nodedev-autostart api: add virNodeDeviceIsPersistent()/IsActive() nodedev: Implement virNodeDeviceIsPersistent()/IsActive() virsh: add nodedev-info docs/manpages/virsh.rst | 27 +++ include/libvirt/libvirt-nodedev.h | 10 + src/conf/node_device_conf.h | 1 + src/conf/virnodedeviceobj.c | 16 ++ src/conf/virnodedeviceobj.h | 6 + src/driver-nodedev.h | 18 ++ src/libvirt-nodedev.c | 141 ++++++++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 6 + src/node_device/node_device_driver.c | 183 +++++++++++++++++- src/node_device/node_device_driver.h | 19 ++ src/node_device/node_device_udev.c | 30 ++- src/remote/remote_driver.c | 6 +- src/remote/remote_protocol.x | 59 +++++- src/remote_protocol-structs | 26 +++ .../nodedevmdevctldata/mdevctl-autostart.argv | 8 + tests/nodedevmdevctltest.c | 54 ++++++ tools/virsh-nodedev.c | 139 +++++++++++++ 18 files changed, 744 insertions(+), 7 deletions(-) create mode 100644 tests/nodedevmdevctldata/mdevctl-autostart.argv -- 2.31.1

[RFC QEMU PATCH] ui: Make the DisplayType enum entries conditional
by Thomas Huth 10 Jun '21

10 Jun '21

Libvirt's "domcapabilities" command has a way to state whether certain graphic frontends are available in QEMU or not. Originally, libvirt looked at the "--help" output of the QEMU binary to determine whether SDL was available or not (by looking for the "-sdl" parameter in the help text), but since libvirt stopped doing this analysis of the help text, the detection of SDL is currently broken, see: https://bugzilla.redhat.com/show_bug.cgi?id=1790902 QEMU should provide a way via the QMP interface instead. The simplest way, without introducing additional commands, is to make the DisplayType enum entries conditional, so that the enum only contains the entries if the corresponding CONFIG_xxx switches have been set. Unfortunately, this only works for sdl, cocoa and spice, since gtk, egl-headless and curses are hard-wired in the "data" section of the DisplayOptions, and thus unfortunately always have to be defined.
