[PATCH v2] util/virutil: Use readpassphrase when libbsd is available
by Jakub Palacky 12 Sep '24

[PATCH 0/2] Adapt to latest libxml2
by Jakub Palacky 12 Sep '24

12 Sep '24

I noticed a couple deprecation errors when trying to build libvirt with the latest libxml2 version from the master branch. These patches fix the deprecated fields. Both functions used are available in the oldest libxml2 version required by libvirt, so there is no need to bump it.

[PATCH] vmx: Allow '*' to appear in VMX file keys
by Richard W.M. Jones 12 Sep '24

12 Sep '24

When connecting to a VMware server (eg using vpx://) we download and try to parse the VMware metadata '*.vmx' file of a guest. In this case a VMX file was found which contained this key: pciPassthru*.present = "False" The '*' character was not previously allowed in keys so this failed to parse with the error: VIR_ERR_CONF_SYNTAX: VIR_FROM_CONF: configuration file syntax error: memory conf:74: expecting an assignment Resolves: https://issues.redhat.com/browse/RHEL-58446 Thanks: Daniel Berrange Signed-off-by: Richard W.M.

[PATCH] Allow apparmor parser to be executed in /usr/bin
by Andrea Bolognani 12 Sep '24

12 Sep '24

From: Tom <libvirt-patch(a)douile.com> This commit modifies the AppArmor profile for virt-aa-helper to accommodate an observed behavior in certain Linux distributions, such as ArchLinux. In these distributions, /usr/sbin symlinks to /usr/bin. To ensure that virt-aa-helper can execute apparmor_parser when it resides in /usr/bin, the profile has been updated accordingly.

[PATCH v2 00/10] Maintainer updates (testing, gdbstub) pre-PR
by Alex Bennée 10 Sep '24

10 Sep '24

Hi, Testing I've updated a number of the docker containers to deal with breakages in the crossdev environments as bullseye moves to LTS. I've dropped the armel environment which doesn't really add much to the armhf cross build we have that works. i686 and mipsel cross containers are bumped up to bookworm. Currently mips64el is still broken. gdbstub This brings in Gustavo's patches to support MTE for system mode expanding on the previously implemented user mode support. plugins I've dropped the TCG plugins from the series so as not to make the pull request too large. I'll roll a new series once I've sent the PR for this. Changes - moved mips64le TCG tests to use the debian-all-test-cross - fixed some --disable-tcg failures for the MTE patches The following still need review: tests/docker: use debian-all-test-cross for mips64el tests Alex Bennée (5): tests/docker: remove debian-armel-cross tests/docker: update debian i686 and mipsel images to bookworm tests/docker: use debian-all-test-cross for mips64el tests docs/devel: fix duplicate line scripts/ci: update the gitlab-runner playbook Gustavo Romero (5): gdbstub: Use specific MMU index when probing MTE addresses gdbstub: Add support for MTE in system mode tests/guest-debug: Support passing arguments to the GDB test script tests/tcg/aarch64: Improve linker script organization tests/tcg/aarch64: Extend MTE gdbstub tests to system mode docs/devel/testing/main.rst | 6 - configure | 7 +- target/arm/gdbstub64.c | 23 ++- .gitlab-ci.d/container-cross.yml | 6 - .gitlab-ci.d/crossbuilds.yml | 7 - scripts/ci/setup/gitlab-runner.yml | 39 +++- .../dockerfiles/debian-armel-cross.docker | 179 ------------------ .../dockerfiles/debian-i686-cross.docker | 10 +- .../dockerfiles/debian-mipsel-cross.docker | 10 +- tests/guest-debug/run-test.py | 6 + tests/guest-debug/test_gdbstub.py | 5 + tests/lcitool/refresh | 10 +- tests/tcg/aarch64/Makefile.softmmu-target | 49 ++++- tests/tcg/aarch64/Makefile.target | 3 +- tests/tcg/aarch64/gdbstub/test-mte.py | 71 ++++--- tests/tcg/aarch64/system/boot.S | 11 ++ tests/tcg/aarch64/system/kernel.ld | 33 ++-- tests/tcg/aarch64/system/mte.S | 109 +++++++++++ 18 files changed, 310 insertions(+), 274 deletions(-) delete mode 100644 tests/docker/dockerfiles/debian-armel-cross.docker create mode 100644 tests/tcg/aarch64/system/mte.S -- 2.39.2

[PATCH 00/26] Maintainer updates (testing, gdbstub, plugins)
by Alex Bennée 10 Sep '24

10 Sep '24

Hi, Here is the current state of my maintainer trees. Testing I've updated a number of the docker containers to deal with breakages in the crossdev environments as bullseye moves to LTS. I've dropped the armel environment which doesn't really add much to the armhf cross build we have that works. i686 and mipsel cross containers are bumped up to bookworm. Currently mips64el is still broken. gdbstub This brings in Gustavo's patches to support MTE for system mode expanding on the previously implemented user mode support. plugins I start by deprecating some options that don't make much sense for instrumentation including 32 bit and TCI support. They will still work but there are caveats and it doesn't seem worth wasting CI time keeping track of them. There are a couple of new plugins including some useful analysis ones. The bbv plugin can generate files that can be fed into simpoint. The cflow plugin I've posted before separately but takes advantage of the new conditional and store helpers to try and be more efficient tracing control flow. Finally there is not one but two memory APIs. Pierrick's updates to the main memory instrumentation now makes values available to the plugins and should be used if you absolutely want to track what value was read or stored. I've added a softmmu test case building on memory.c and I'll merge the updated linux-user test case once its been re-spun. Rowan's API provides a more direct access through the existing debug API but comes with the caveats that it should only used on memory you don't expect to be changing. The example provided allows for the contents of syscalls to be probed at the syscall point. Finally there is a RFC for a gdbstub hook which I mostly wrote while I was debugging weirdness in the memory stuff. I'll probably drop it before the PR and let it cook a bit more on plugins/next. The following still need review: plugins: add ability to register a GDB triggered callback util/timer: avoid deadlock when shutting down tests/tcg: add a system test to check memory instrumentation tests/tcg: only read/write 64 bit words on 64 bit systems tests/tcg: clean up output of memory system test contrib/plugins: control flow plugin deprecation: don't enable TCG plugins by default with TCI deprecation: don't enable TCG plugins by default on 32 bit hosts scripts/ci: update the gitlab-runner playbook docs/devel: fix duplicate line tests/docker: update debian i686 and mipsel images to bookworm tests/docker: remove debian-armel-cross Akihiko Odaki (1): contrib/plugins: Add a plugin to generate basic block vectors Alex Bennée (12): tests/docker: remove debian-armel-cross tests/docker: update debian i686 and mipsel images to bookworm docs/devel: fix duplicate line scripts/ci: update the gitlab-runner playbook deprecation: don't enable TCG plugins by default on 32 bit hosts deprecation: don't enable TCG plugins by default with TCI contrib/plugins: control flow plugin tests/tcg: clean up output of memory system test tests/tcg: only read/write 64 bit words on 64 bit systems tests/tcg: add a system test to check memory instrumentation util/timer: avoid deadlock when shutting down plugins: add ability to register a GDB triggered callback Gustavo Romero (5): gdbstub: Use specific MMU index when probing MTE addresses gdbstub: Add support for MTE in system mode tests/guest-debug: Support passing arguments to the GDB test script tests/tcg/aarch64: Improve linker script organization tests/tcg/aarch64: Extend MTE gdbstub tests to system mode Pierrick Bouvier (5): plugins: save value during memory accesses plugins: extend API to get latest memory value accessed tests/tcg: add mechanism to run specific tests with plugins tests/tcg: allow to check output of plugins tests/plugin/mem: add option to print memory accesses Rowan Hart (2): plugins: add plugin API to read guest memory plugins: add option to dump write argument to syscall plugin Thomas Huth (1): contrib/plugins/Makefile: Add a 'distclean' target docs/about/deprecated.rst | 19 + docs/about/emulation.rst | 44 +- docs/devel/testing/main.rst | 6 - configure | 37 +- accel/tcg/atomic_template.h | 66 ++- include/hw/core/cpu.h | 4 + include/qemu/plugin-event.h | 1 + include/qemu/plugin.h | 4 + include/qemu/qemu-plugin.h | 80 +++- plugins/plugin.h | 9 + contrib/plugins/bbv.c | 158 +++++++ contrib/plugins/cflow.c | 413 ++++++++++++++++++ plugins/api.c | 71 +++ plugins/core.c | 43 ++ target/arm/gdbstub64.c | 21 +- tcg/tcg-op-ldst.c | 66 ++- tests/tcg/multiarch/system/memory.c | 123 ++++-- tests/tcg/plugins/mem.c | 254 ++++++++++- tests/tcg/plugins/syscall.c | 117 +++++ util/qemu-timer.c | 14 +- accel/tcg/atomic_common.c.inc | 13 +- accel/tcg/ldst_common.c.inc | 38 +- .gitlab-ci.d/buildtest.yml | 2 + .gitlab-ci.d/container-cross.yml | 6 - .gitlab-ci.d/crossbuilds.yml | 7 - contrib/plugins/Makefile | 4 +- plugins/qemu-plugins.symbols | 3 + scripts/ci/setup/gitlab-runner.yml | 39 +- .../dockerfiles/debian-armel-cross.docker | 179 -------- .../dockerfiles/debian-i686-cross.docker | 10 +- .../dockerfiles/debian-mipsel-cross.docker | 10 +- tests/guest-debug/run-test.py | 6 + tests/guest-debug/test_gdbstub.py | 5 + tests/lcitool/refresh | 10 +- tests/tcg/Makefile.target | 12 +- tests/tcg/aarch64/Makefile.softmmu-target | 49 ++- tests/tcg/aarch64/Makefile.target | 3 +- tests/tcg/aarch64/gdbstub/test-mte.py | 71 ++- tests/tcg/aarch64/system/boot.S | 11 + tests/tcg/aarch64/system/kernel.ld | 33 +- tests/tcg/aarch64/system/mte.S | 109 +++++ tests/tcg/alpha/Makefile.softmmu-target | 2 +- .../multiarch/system/Makefile.softmmu-target | 6 + .../system/validate-memory-counts.py | 115 +++++ 44 files changed, 1935 insertions(+), 358 deletions(-) create mode 100644 contrib/plugins/bbv.c create mode 100644 contrib/plugins/cflow.c delete mode 100644 tests/docker/dockerfiles/debian-armel-cross.docker create mode 100644 tests/tcg/aarch64/system/mte.S create mode 100755 tests/tcg/multiarch/system/validate-memory-counts.py -- 2.39.2
