[PATCH] test: Fix testNodeGetFreePages
by Martin Kletzander 26 Sep '23

26 Sep '23

The function is supposed to return the number of items filled into the array and not zero. Also change the initialization of the "randomness" to be based on the startCell so that the values are different for each cell even for separate calls.

[libvirt PATCH v2] util: fix success return for virProcessKillPainfullyDelay()
by Jonathon Jongsma 26 Sep '23

26 Sep '23

virProcessKillPainfullyDelay() currently almost always returns 1 or -1, even though the documentation indicates that it should return 0 if the process was terminated gracefully. But the computation of the return code is faulty and the only case that it currently returns 0 is when it is called with the pid of a process that does not exist. Since no callers ever even distinguish between the 0 and 1 response codes, simply get rid of the distinction and return 0 for both cases. Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com> --- Change in v2: - just drop the distinction between 0 and 1 and always return 0.

[libvirt PATCH v3 00/10] external snapshot revert fixes
by Pavel Hrdina 26 Sep '23

This fixes reverting external snapshots to not error out in cases where it should work and makes it correctly load the memory state when reverting to snapshot of running VM. This discards v2 completely and makes changes to v1: - moves qemuSaveImageStartProcess to qemu_process as qemuProcessStartWithMemoryState - change it to use cookie from memory state file instead of using cookie from snapshot xml - comments improvements - introduces new helpers to start and stop decompression process - reintroduces <externalSnapshot/> capability Pavel Hrdina (10): qemu_saveimage: extract starting process to qemuSaveImageStartProcess qemu_saveimage: introduce helpers to decompress memory state file qemu_saveimage: move qemuSaveImageStartProcess to qemu_process qemuProcessStartWithMemoryState: allow setting reason for audit log qemuProcessStartWithMemoryState: add snapshot argument qemuProcessStartWithMemoryState: make it possible to use without data qemu_snapshot: fix reverting external snapshot when not all disks are included qemu_snapshot: correctly load the saved memory state file capabilities: report full external snapshot support NEWS: document support for reverting external snapshots NEWS.rst | 8 + docs/formatcaps.rst | 7 + src/conf/capabilities.c | 1 + src/conf/capabilities.h | 1 + src/conf/schemas/capability.rng | 5 + src/qemu/qemu_capabilities.c | 1 + src/qemu/qemu_process.c | 95 +++++++++ src/qemu/qemu_process.h | 13 ++ src/qemu/qemu_saveimage.c | 189 +++++++++++------- src/qemu/qemu_saveimage.h | 15 ++ src/qemu/qemu_snapshot.c | 91 ++++++--- .../qemucaps2xmloutdata/caps.aarch64+hvf.xml | 1 + tests/qemucaps2xmloutdata/caps.aarch64.xml | 1 + tests/qemucaps2xmloutdata/caps.ppc.xml | 1 + tests/qemucaps2xmloutdata/caps.ppc64.xml | 1 + tests/qemucaps2xmloutdata/caps.riscv64.xml | 1 + tests/qemucaps2xmloutdata/caps.s390x.xml | 1 + tests/qemucaps2xmloutdata/caps.sparc.xml | 1 + tests/qemucaps2xmloutdata/caps.x86_64+hvf.xml | 1 + tests/qemucaps2xmloutdata/caps.x86_64.xml | 1 + 20 files changed, 328 insertions(+), 107 deletions(-) -- 2.41.0

[RFC PATCH libvirt v1 0/3] Ensure full early console access with libvirt
by Marc Hartmayer 26 Sep '23

26 Sep '23

Currently, early console output may be lost, e.g. if starting a guest with `virsh start --console` guest, which can make debugging of early failures very difficult (like zipl messages or disabled wait conditions happening early). This is because QEMU may emit serial console output before the libvirt console client starts to consume data from the pts. This can be prevented by starting the guest in paused state, connect to the console and then resume the guest. Note: There is still a problem in QEMU itself, see QEMU patch series `[PATCH] chardev/char-pty: Avoid losing bytes when the other side just (re-)connected` [1] [1] https://lists.gnu.org/archive/html/qemu-devel/2023-08/msg02725.html Marc Hartmayer (3): virsh: add `console --resume` support Improve `virsh start --console` behavior Improve `virsh create --console` behavior tools/virsh-console.c | 8 ++++++++ tools/virsh-console.h | 1 + tools/virsh-domain.c | 32 ++++++++++++++++++++++++++------ 3 files changed, 35 insertions(+), 6 deletions(-) base-commit: 3fd64fb0e236fc80ffa2cc977c0d471f11fc39bf -- 2.34.1

[PATCH 00/31] September maintainer omnibus (tests, gdbstub, plugins)
by Alex Bennée 26 Sep '23

26 Sep '23

Hi, This wraps up my current testing, gdbstub and plugin trees in an attempt to do my part to reduce the qemu-devel fire hose. For testing we have a number of cleanups to configure to better handle selecting the container engine (removing the ability to dynamically switch). I had to do this as one of my build boxes has recently acquired a broken podman install. There are also some updates to avocado sbsa-ref as well as tweaks to the gitlab setup to minimise the amount of wheel spinning we do. The deprecation of CRIS is a little provocative but if we do want to keep it we need to stop relying on a rapidly dated fedora image to do it. Finally we include the swtpm package to widen the testing we do through avocado. The gdbstub updates are from Akihiko and include a bunch of clean-ups that will hopefully pave the way for another series which allows the plugins to access register values using the gdb backend to source the data. Finally the plugins has a few fixes which includes a tweak to make SH4 atomic modelling more plugin friendly. This allows for Matt's fix to deal with non-regular instruction encoding spanning pages. I also fix a number of coverity warnings. The final time control patches are still RFC and not ready for merging but I include them for completeness. The following still need review: contrib/plugins: add iops plugin example for cost modelling plugins: add time control API sysemu: generalise qtest_warp_clock as qemu_clock_advance_virtual_time qtest: use cpu interface in qtest_clock_warp (1 acks, 1 sobs, 0 tbs) contrib/plugins: fix coverity warning in hotblocks contrib/plugins: fix coverity warning in lockstep contrib/plugins: fix coverity warning in cache configure: ensure dependency for cross-compile setup configure: remove gcc version suffixes configure: allow user to override docker engine tests/docker: make docker engine choice entirely configure driven docs: mark CRIS support as deprecated tests/lcitool: add swtpm to the package list Akihiko Odaki (12): gdbstub: Fix target_xml initialization gdbstub: Fix target.xml response plugins: Check if vCPU is realized contrib/plugins: Use GRWLock in execlog gdbstub: Introduce GDBFeature structure target/arm: Move the reference to arm-core.xml hw/core/cpu: Return static value with gdb_arch_name() gdbstub: Use g_markup_printf_escaped() target/arm: Remove references to gdb_has_xml target/ppc: Remove references to gdb_has_xml gdbstub: Remove gdb_has_xml variable gdbstub: Replace gdb_regs with an array Alex Bennée (15): tests/lcitool: add swtpm to the package list gitlab: shuffle some targets and reduce avocado noise docs: mark CRIS support as deprecated tests/docker: make docker engine choice entirely configure driven configure: allow user to override docker engine configure: remove gcc version suffixes configure: ensure dependency for cross-compile setup contrib/plugins: fix coverity warning in cache contrib/plugins: fix coverity warning in lockstep contrib/plugins: fix coverity warning in hotblocks sysemu: add set_virtual_time to accel ops qtest: use cpu interface in qtest_clock_warp sysemu: generalise qtest_warp_clock as qemu_clock_advance_virtual_time plugins: add time control API contrib/plugins: add iops plugin example for cost modelling Marcin Juszkiewicz (1): tests/avocado: update firmware to enable sbsa-ref/neoverse-v1 Matt Borgerson (1): plugins: Set final instruction count in plugin_gen_tb_end Richard Henderson (2): accel/tcg: Add plugin_enabled to DisasContextBase target/sh4: Disable decode_gusa when plugins enabled MAINTAINERS | 2 +- docs/about/deprecated.rst | 11 + configure | 15 +- meson.build | 2 +- gdbstub/internals.h | 2 - include/exec/gdbstub.h | 17 +- include/exec/plugin-gen.h | 4 +- include/exec/translator.h | 2 + include/hw/core/cpu.h | 4 +- include/qemu/qemu-plugin.h | 19 ++ include/qemu/timer.h | 15 + include/sysemu/accel-ops.h | 18 +- include/sysemu/cpu-timers.h | 27 +- include/sysemu/qtest.h | 1 + target/ppc/internal.h | 2 +- accel/qtest/qtest.c | 1 + accel/tcg/plugin-gen.c | 6 +- accel/tcg/translator.c | 3 +- contrib/plugins/cache.c | 18 +- contrib/plugins/execlog.c | 16 +- contrib/plugins/hotblocks.c | 2 +- contrib/plugins/iops.c | 261 ++++++++++++++++++ contrib/plugins/lockstep.c | 13 +- gdbstub/gdbstub.c | 95 +++---- gdbstub/softmmu.c | 2 +- plugins/api.c | 28 ++ plugins/core.c | 2 +- softmmu/cpus.c | 11 + softmmu/qtest.c | 26 +- ...t-virtual-clock.c => cpus-virtual-clock.c} | 5 + stubs/gdbstub.c | 6 +- target/arm/cpu.c | 9 +- target/arm/cpu64.c | 4 +- target/arm/gdbstub.c | 32 +-- target/i386/cpu.c | 6 +- target/loongarch/cpu.c | 8 +- target/ppc/gdbstub.c | 24 +- target/riscv/cpu.c | 6 +- target/s390x/cpu.c | 4 +- target/sh4/translate.c | 41 ++- target/tricore/cpu.c | 4 +- util/qemu-timer.c | 26 ++ .gitlab-ci.d/buildtest.yml | 15 +- .gitlab-ci.d/cirrus/macos-12.vars | 2 +- contrib/plugins/Makefile | 1 + plugins/qemu-plugins.symbols | 2 + scripts/feature_to_c.py | 48 ++++ scripts/feature_to_c.sh | 69 ----- stubs/meson.build | 2 +- tests/avocado/machine_aarch64_sbsaref.py | 25 +- tests/docker/Makefile.include | 7 +- tests/docker/dockerfiles/alpine.docker | 1 + tests/docker/dockerfiles/centos8.docker | 1 + .../dockerfiles/debian-amd64-cross.docker | 1 + tests/docker/dockerfiles/debian-amd64.docker | 1 + .../dockerfiles/debian-arm64-cross.docker | 1 + .../dockerfiles/debian-armhf-cross.docker | 1 + .../dockerfiles/debian-ppc64el-cross.docker | 1 + .../dockerfiles/debian-s390x-cross.docker | 1 + .../dockerfiles/fedora-win32-cross.docker | 1 + .../dockerfiles/fedora-win64-cross.docker | 1 + tests/docker/dockerfiles/fedora.docker | 1 + tests/docker/dockerfiles/opensuse-leap.docker | 1 + tests/docker/dockerfiles/ubuntu2204.docker | 1 + tests/lcitool/libvirt-ci | 2 +- tests/lcitool/projects/qemu.yml | 1 + 66 files changed, 689 insertions(+), 298 deletions(-) create mode 100644 contrib/plugins/iops.c rename stubs/{cpus-get-virtual-clock.c => cpus-virtual-clock.c} (68%) create mode 100755 scripts/feature_to_c.py delete mode 100644 scripts/feature_to_c.sh -- 2.39.2

[PATCH v3] interface: fix udev_device_get_sysattr_value return value check
by Dmitry Frolov 25 Sep '23

25 Sep '23

Reviewing the code I found that return value of function udev_device_get_sysattr_value() is dereferenced without a check. udev_device_get_sysattr_value() may return NULL by number of reasons. v2: VIR_DEBUG added, replaced STREQ(NULLSTR()) with STREQ_NULLABLE() v3: More checks added, to skip earlier.

[libvirt PATCH 1/2] util: Fix error return for virProcessKillPainfullyDelay()
by Jonathon Jongsma 25 Sep '23

25 Sep '23

Commit 93af79fb removed a cleanup label in favor of returning error values directly in certain cases. But the final return value was changed from -1 to 0. If we get to the end of the function, that means that we've waited for the process to exit but it still exists. So we should return -1. The error message was still being set correctly, but we were returning a success status (0).

In a modular daemon configuration, virtxend does not support the virNetwork* APIs.

[libvirt PATCH v8 00/37] Use nbdkit for http/ftp/ssh network drives in libvirt
by Jonathon Jongsma 23 Sep '23

23 Sep '23

This is the eighth version of this patch series. See https://bugzilla.redhat.com/show_bug.cgi?id=2016527 for more information. Note that testing this requires selinux policy changes which are not fully done, but there is a new policy in development that has allowed me to run with selinux in enforcing mode for the common cases. See https://bugzilla.redhat.com/show_bug.cgi?id=2182505 for more information. The following scenarios should work now with selinux enabled using the selinux policy from that bug: - http/https disks - ssh disks with password authentication - ssh disks with passwordless keyfile The one major thing that doesn't work and is difficult to get working with selinux enabled is the ssh-agent. This is because there doesn't seem to be any selinux policy for ssh-agent, so by default the ssh-agent socket is labeled unconfined_t. We cannot allow access from the libvirt/qemu to unconfined_t because that would open up access to just about anything on the host. So additional work will likely be necessary for ssh-agent/libvirt interaction in the future. Fortunately ssh-agent is something that never was really supported with the old qemu block driver either, so I think we could potentially merge this patchset either without the ssh-agent patches or with a note that ssh-agent won't work with selinux enabled. Changes in v8: - Hopefully addressed all of Peter's issues, in addition to: - updated documentation to say 9.8.0, since 9.7.0 is currently in freeze - used WITH_NBDKIT instead of WITH_DECL_SYS_PIDFD_OPEN to make the code a bit more concise and understandable - enabled ci by adding libnbd to the dependencies, which uncovered a couple additional minor issues with those platforms that don't support the pidfd_open syscall - don't run nbdkit tests when WITH_NBDKIT is not defined - avoid warnings with unused function arguments - note that the ubuntu containers are currently failing due to a LeakSanitizer error, but I haven't reproduced it locally and can't figure out how to get better information from the leak sanitizer. Pointers appreciated: https://gitlab.com/jjongsma/libvirt/-/jobs/4991631193 - One change of note is a new patch "qemu: improve error handling when restarting nbdkit". In order to provide better error reporting to the user and avoid VIR_WARN as suggested by Peter, some functions now return an error and this error is propagated up to qemuProcessReconnect(). This could potentially result in running domains being killed upon a libvirt restart, but only if they were in a state where they were was not a running nbdkit backend or libvirt couldn't monitor the process nbdkit.
