This removes minor version number from OpenSUSE LEAP target names and on CentOS Stream 9 installs flake8 from repositories, instead of pip.

[PATCH 0/2] tools: virsh-domain: display progress with enhanced granularity
by Shaleen Bathla 27 Apr '23

27 Apr '23

While working with active blockcommit using virsh/libvirt, we found that in case of heavy IO, the progress may stay stuck at 99% for quite a while. It will be much better if we show progress upto 2 decimal places more precise which should be sufficient for most scenarios for now. This will give a user, a better understanding of the progress of blockjob/blockcommit etc This patch intends to do exactly that by adding more granularity to blockjob/blockcommit etc progress.

[libvirt PATCH] run: add ability to set selinux context
by Jonathon Jongsma 27 Apr '23

27 Apr '23

When running libvirt from the build directory with the 'run' script, it will run as unconfined_t. This can result in unexpected behavior when selinux is enforcing due to the fact that the selinux policies are written assuming that libvirt is running with the system_u:system_r:virtd_t context. This patch adds a new --selinux option to the run script. When this option is specified, it will launch the specified binary using the 'runcon' utility to set its selinux context to the one mentioned above. Since this requires root privileges, setting the selinux context is not the default behavior and must be enabled with the command line switch.

[PATCH v2] vfio/pci: Propagate ACPI notifications to user-space via eventfd
by Grzegorz Jaszczyk 25 Apr '23

25 Apr '23

To allow pass-through devices receiving ACPI notifications, permit to register ACPI notify handler (via introduced new ioctl) for a given device. The handler role is to receive and propagate such ACPI notifications to the user-space through the user provided eventfd. This allows VMM to receive and propagate them further to the VM, where the actual driver for pass-through device resides and can react to device specific notifications accordingly. The eventfd usage ensures VMM and device isolation: it allows to use a dedicated channel associated with the device for such events, such that the VMM has direct access. Since the eventfd counter is used as ACPI notification value placeholder, the eventfd signaling needs to be serialized in order to not end up with notification values being coalesced. Therefore ACPI notification values are buffered and signalized one by one, when the previous notification value has been consumed. Signed-off-by: Grzegorz Jaszczyk <jaz(a)semihalf.com> --- Changelog v1..v2: - The v2 implementation is actually completely different then v1: instead of using acpi netlink events for propagating ACPI notifications to the user space take advantage of eventfd, which can provide better VMM and device isolation: it allows to use a dedicated channel associated with the device for such events, such that the VMM has direct access. - Using eventfd counter as notification value placeholder was suggested in v1 and requires additional serialization logic introduced in v2. - Since the vfio-pci supports non-ACPI platforms address !CONFIG_ACPI case. - v1 discussion: https://patchwork.kernel.org/project/kvm/patch/20230307220553.631069-1-jaz@… --- drivers/vfio/pci/vfio_pci_core.c | 215 +++++++++++++++++++++++++++++++ include/linux/vfio_pci_core.h | 11 ++ include/uapi/linux/vfio.h | 15 +++ 3 files changed, 241 insertions(+) diff --git a/drivers/vfio/pci/vfio_pci_core.c b/drivers/vfio/pci/vfio_pci_core.c index a5ab416cf476..ba8c49217875 100644 --- a/drivers/vfio/pci/vfio_pci_core.c +++ b/drivers/vfio/pci/vfio_pci_core.c @@ -10,6 +10,7 @@ #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt +#include <linux/acpi.h> #include <linux/aperture.h> #include <linux/device.h> #include <linux/eventfd.h> @@ -679,6 +680,70 @@ void vfio_pci_core_disable(struct vfio_pci_core_device *vdev) } EXPORT_SYMBOL_GPL(vfio_pci_core_disable);

[PATCH] meson: Work around configure_file(copy:true) deprecation
by Michal Privoznik 21 Apr '23

21 Apr '23

In our meson scripts, we use configure_file(copy:true) to copy files from srcdir into builddir. However, as of meson-0.64.0, this is deprecated [1] in favor of using: fs = import('fs') fs.copyfile(in, out) Except, the submodule's new method wasn't introduced until 0.64.0. And since we can't bump the minimal meson version we require, we have to work with both: new and old versions. Now, the fun part: fs.copyfile() is not a drop in replacement as it returns different type (a custom_target object). This is incompatible with places where we store the configure_file() retval in a variable to process it further. While we could just replace 'copy:true' with a dummy 'configuration:...' (say 'configuration: configmake_conf') we can't do that for binary files (like src/fonts/ or src/images/). Therefore, places where we are not interested in the retval can be switched to fs.copyfile() and places where we are interested in the retval will just use a dummy 'configuration:'. Except, src/network/meson.build. In here we not just copy the file but also specify alternative install dir and that's not something that fs.copyfile() can handle. Yet, using 'copy: true' is viewed wrong [2]. 1: https://mesonbuild.com/Release-notes-for-0-64-0.html#fscopyfile-to-replace-… 2: https://github.com/mesonbuild/meson/pull/10042 Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- docs/css/meson.build | 6 +++++- docs/fonts/meson.build | 6 +++++- docs/images/meson.build | 6 +++++- docs/js/meson.build | 8 ++++++-- docs/logos/meson.build | 6 +++++- docs/meson.build | 6 +++++- meson.build | 3 +++ src/locking/meson.build | 8 ++++---- src/network/meson.build | 2 +- 9 files changed, 39 insertions(+), 12 deletions(-) diff --git a/docs/css/meson.build b/docs/css/meson.build index 384f6e789f..a2a2ccfb28 100644 --- a/docs/css/meson.build +++ b/docs/css/meson.build @@ -11,7 +11,11 @@ install_data(docs_css_files, install_dir: docs_html_dir / 'css') foreach file : docs_css_files # This hack enables us to view the web pages # from within the uninstalled build tree -

[libvirt PATCH] qemu: Allow sockets in long or deep paths.
by Nick Guenther 20 Apr '23

20 Apr '23

The qemu driver creates IPC sockets using absolute paths, but under POSIX socket paths are constrained pretty tightly. On systems with homedirs on an unusual mount point, like network homedirs, or just particularly long usernames, this could make starting VMs under qemu:///session impossible.
