[libvirt] [PATCH] test_driver: implement virDomainSendProcessSignal
by Ilias Stamatis 19 Jun '19

19 Jun '19

Only succeed when @pid_value is 1, since according to the docs this is the minimum requirement for any driver to implement this API. >From man 2 kill: The only signals that can be sent to process ID 1, the init process, are those for which init has explicitly installed signal handlers. Regarding sending SIGTERM and SIGKILL to init, the test driver domains pretend to run Linux, and on Linux init/systemd explicitly ignores these signals. Correspondingly, we can assume that no signal handlers are installed for any other signal and succeed by doing nothing.

[libvirt] [PATCH] apparmor: Add openGraphicsFD rule for named profile
by Christian Ehrhardt 19 Jun '19

19 Jun '19

Commit a3ab6d42 changed the libvirtd profile to a named profile but neglected to accommodate the change in the qemu profile ptrace and signal rules. Later on 4ec3cf9a fixed that for ptrace and signal but openGraphicsFD is still missing. As a result, libvirtd is unable to open UI on libvirt >=5.1 e.g. with virt-manager. Add openGraphicsFD rule that references the libvirtd profile by name in addition to full binary path.

[libvirt] [PATCH] remote: use VIR_DRV_OPEN_REMOTE_USER in ssh transport checks
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

We currently refuse to connect to remote libvirtd over SSH if we see the path ends in /session. Earlier on though we checked for /session and set the VIR_DRV_OPEN_REMOTE_USER flag. There is one subtle distinction though with the test driver. All test URIs are marked with this flag, regardless of whether the URI indicates a local or remote connection. Previously a local connection to the test driver would have used the unprivileged libvirtd while a remote connection would have tried the privileged libvirtd. With this we are consistent and use the unprivileged for both local & remote, if the current user is non-root. Signed-off-by: Daniel P.

[libvirt] [PATCH 0/3] qemu: Introduce 'features' QMP query (blockdev-add saga)
by Peter Krempa 19 Jun '19

19 Jun '19

qemu introduced a new field in the QMP schema which allows to query features for a schema entry. Add the support to libvirt for querying it. Patch 3/3 is part of my blockdev series and I don't mind holding on to it until I post patches which make use of it. It's posted here mostly for demonstration purpose. Peter Krempa (3): tests: qemucaps: Introduce test data for qemu 4.1.0 qemu: qapi: Implement support for 'features' qemu: caps: Add capability for dynamic 'auto-read-only' support for files src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_qapi.c | 41 + .../caps_4.1.0.x86_64.replies | 23482 ++++++++++++++++ .../caps_4.1.0.x86_64.xml | 1388 + 5 files changed, 24914 insertions(+) create mode 100644 tests/qemucapabilitiesdata/caps_4.1.0.x86_64.replies create mode 100644 tests/qemucapabilitiesdata/caps_4.1.0.x86_64.xml -- 2.21.0
