[PATCH 00/14] virsh: Completion improvements and checking tool
by Peter Krempa
When inspecting whether https://gitlab.com/libvirt/libvirt/-/issues/9 is
still valid I wrote a tool which outputs command options missing
completers. Now that I had a bit of time with lot of interruptions which
is ideal for going through such a thing I decided to clean up
the tool and post it along with a few fixes and additions to completers.
After this patchset the following completers are still missing:
$ virsh self-test --completers-missing

vol-create-as: format, backing-vol, backing-vol-format
vol-download: file
vol-wipe: algorithm

The list is not so long any more. Mostly missing completers are for
remote file paths (passed to libvirt or the VM itself), few enums,
guest-agent-based user list and a few which need to be assesed.

[libvirt PATCH] gitlab: remove obsolete job rules for TEMPORARILY_DISABLED variable
by Daniel P. Berrangé
We previously had a 'rules:' entry that caused a job to be skipped if
the variable "TEMPORARILY_DISABLED" was set. This is no longer needed
since we can set a similar flag in ci/manifest.yml and re-generate
to temporarily skip a job.
Unfortunately the 'rules:' entry had an unexpected side-effect on
the pipelines that was never previously noticed. Instead of only
running pipelines on push, the mere existance of the 'rules:' entry
caused triggering of pipelines on merge requests too.
The newly auto-generated ci/gitlab.yml file does not have a 'rules:'
for the container job template, and thus only runs on git push.
The result is that build jobs try to run on merge requests and the
container jobs they depend on don't exist. This breaks the entire
pipeline with a message that the config is invalid due to broken
job dependencies.
This fixes a regression introduced in

This isn't possible (acpi index is set when devices are probed at
guest startup) and libvirt wasn't even trying to communicate the
change to the guest in any way, but instead of logging an error, we
were just pretending the request had succeeded.

[libvirt PATCH 0/3] Reduce stack frame size of virNWFilterRuleDefFixup
by Tim Wiederhake
When libvirt is build with sanitizers enabled, in debug mode, on clang,
virNWFilterRuleDefFixup exceeds the maximum stack frame size of 8192 bytes,
as specified in meson.build:
../src/conf/nwfilter_conf.c:2190:1: error: stack frame size of 10616
bytes in function 'virNWFilterRuleDefFixup' [-Werror,-Wframe-larger-than=]
virNWFilterRuleDefFixup(virNWFilterRuleDef *rule)
^
1 error generated.
This series reworks the function a bit to bring the frame size below 8192.

Tim

[libvirt PATCH v3 0/1] Add a PCI/PCIe device VPD Capability
by Dmitrii Shcherbakov
Add support for deserializing the binary PCI/PCIe VPD format and
exposing VPD resources as XML elements in a new nested capability
of PCI/PCIe devices called 'vpd'.
The VPD format is specified in "I.3. VPD Definitions" in PCI specs
(2.2+) and "6.28.1 VPD Format" PCIe 4.0. As section 6.28 in PCIe 4.0
notes, the PCI Local Bus and PCIe VPD formats are binary compatible
and PCIe 4.0 merely started incorporating what was already present in
PCI specs.
Linux kernel exposes a binary blob in the VPD format via sysfs since
v2.6.26 (commit 94e6108803469a37ee1e3c92dafdd1d59298602f) which requires
a parser to interpret.
There are usage scenarios where information such as the board serial
number needs to be retrieved from PCI(e) VPD. Projects like Nova can
utilize this information for cases which involve virtual interface
plugging on SmartNIC DPUs but there may be other scenarios and types of
information useful to retrieve from VPD. The fact that the format is
binary requires proper parsing instead of substring searching hence the
full parser is proposed. Likewise, checksum validation requires proper
parsing as well.
The patch follows a prior discussion on the mailing list which has
additional context about the use-case but a narrower proposal:
https://listman.redhat.com/archives/libvir-list/2021-May/msg00873.html
https://www.mail-archive.com/libvir-list@redhat.com/msg218165.html
The new functionality is mostly contained in virpcivpd with a
couple of new functions added to virpci. Additionally, the necessary XML
serialization/deserialization and glue code is added to expose the VPD
capability to external clients as XML.
A new capability flag is added along with a new capability in order to
allow for filtering of PCI devices with the VPD capability using virsh:
virsh nodedev-list --cap vpd
sudo virsh nodedev-dumpxml --device pci_dddd_bb_ss_f
In this example having the root uid is required in order to access the
vpd sysfs entry, therefore, the nodedev XML output will only contain
the VPD capability if virsh is run as root.
The capability is treated as dynamic due to the presence of read-write
sections in the VPD format per PCI/PCIe specs (the idea being that
read-write resource fields may potentially be altered by the DPU OS
over time independently from the host OS).
Unit tests cover the parser functionality (including many possible
invalid cases), in-memory representation as well as XML serialization
and deserialization.
Manual functional testing was performed with 2 DPUs and several other
NIC models which expose PCI(e) VPD. Testing have also been performed
for devices that do not have VPD or those that expose a VPD capability
but exhibit invalid behavior (I/O errors while reading a sysfs entry).
Per the existing guidelines, the implementation relies heavily on glib
for various purposes.
https://libvirt.org/glib-adoption.html
v3 of the patch is a rebase of v2 on top of the latest changes to the
master branch.
