[libvirt] [PATCH v3 00/15] implement cgroups v2 support
by Pavel Hrdina 18 Jun '19

18 Jun '19

In cgroups v2 there is no devices controller, eBPF should be used instead. Changes in v3: - removed workaround for kernel bug [1] - added documentation how to get the eBPF program Changes in v2: - fixed build on bsd and older kernels without cgroup BPF - cgroup bpf devices code moved to separate file Documentation for eBPF: <http://man7.org/linux/man-pages/man2/bpf.2.html> <https://www.kernel.org/doc/Documentation/networking/filter.txt> <https://docs.cilium.io/en/v1.3/bpf/> [1] <https://bugzilla.redhat.com/show_bug.cgi?id=1656432> Pavel Hrdina (15): util: introduce virbpf helpers vircgroup: introduce virCgroupV2DevicesAvailable vircgroup: introduce virCgroupV2DevicesAttachProg vircgroup: introduce virCgroupV2DevicesDetectProg vircgroup: introduce virCgroupV2DevicesCreateProg vircgroup: introduce virCgroupV2DevicesPrepareProg vircgroup: introduce virCgroupV2DevicesRemoveProg vircgroup: introduce virCgroupV2DeviceGetPerms vircgroup: introduce virCgroupV2DevicesGetKey vircgroup: introduce virCgroupV2AllowDevice vircgroup: introduce virCgroupV2DenyDevice vircgroup: introduce virCgroupV2AllowAllDevices vircgroup: introduce virCgroupV2DenyAllDevices vircgroup: workaround devices in hybrid mode vircgroupmock: mock virCgroupV2DevicesAvailable configure.ac | 6 + include/libvirt/virterror.h | 2 + src/Makefile.am | 2 + src/libvirt_private.syms | 26 ++ src/util/Makefile.inc.am | 4 + src/util/virbpf.c | 438 +++++++++++++++++++ src/util/virbpf.h | 259 ++++++++++++ src/util/vircgroup.c | 3 +- src/util/vircgroupbackend.h | 3 +- src/util/vircgrouppriv.h | 10 + src/util/vircgroupv1.c | 9 +- src/util/vircgroupv2.c | 117 +++++- src/util/vircgroupv2devices.c | 670 ++++++++++++++++++++++++++++++ src/util/vircgroupv2devices.h | 57 +++ src/util/virerror.c | 2 + tests/vircgroupdata/hybrid.parsed | 2 +- tests/vircgroupmock.c | 7 + tests/vircgrouptest.c | 4 +- 18 files changed, 1613 insertions(+), 8 deletions(-) create mode 100644 src/util/virbpf.c create mode 100644 src/util/virbpf.h create mode 100644 src/util/vircgroupv2devices.c create mode 100644 src/util/vircgroupv2devices.h -- 2.20.1

[libvirt] [PATCH RFC 0/1] mdevctl: further config for vfio-ap
by Cornelia Huck 18 Jun '19

18 Jun '19

This patch adds a very rough implementation of additional config data for mdev devices. The idea is to make it possible to specify some type-specific key=value pairs in the config file for an mdev device. If a device is started automatically, the device is stopped and restarted after applying the config. The code has still some problems, like not doing a lot of error handling and being ugly in general; but most importantly, I can't really test it, as I don't have the needed hardware. Feedback welcome; would be good to know if the direction is sensible in general.

[libvirt] [PATCH 0/4] docs: Use CDNJS, update JavaScript libraries
by Andrea Bolognani 18 Jun '19

18 Jun '19

We're carrying around embedded copies of a few JavaScript libraries for use in our homepage, and we've been unforgivably bad at keeping them up to date. Instead of serving JavaScript from libvirt.org, use CDNJS so that users will get better performance and the load on our Web server will decrease (win-win!); at the same time, move from the positively ancient versions we're currently using to the freshest ones available.

[libvirt] [PATCH v3] Produce more verbose error if cppi not found
by Michal Privoznik 17 Jun '19

17 Jun '19

It's fairly easy (especially for new contributors) to not spot the 'cppi not installed' line in the syntax-check output. Turn it into a banner that is more visible and at the same time add it as a build dependency. Unfortunately, RHEL doesn't ship cppi so we can add the dependency only for Fedora. Since it's v1 this has effectively became code copied over from Andrea's review suggestions.

[libvirt] [PATCH v2] Produce more verbose error if cppi not found
by Michal Privoznik 17 Jun '19

17 Jun '19

It's fairly easy (especially for new contributors) to not spot the 'cppi not installed' line in the syntax-check output. Turn it into a banner that is more visible and at the same time add it as a build dependency. Unfortunately, RHEL doesn't ship cppi so we can add the dependency only for Fedora.
