[PULL 31/31] linux-user: Remove the deprecated ppc64abi32 target
by Alex Bennée
From: Thomas Huth <thuth(a)redhat.com>
It's likely broken, and nobody cared for picking it up again
during the deprecation phase, so let's remove this now.
Since this is the last entry in deprecated_targets_list, remove
the related code in the configure script, too.

[PATCH] virhostcpu: fix getting CPU freq for Apple Silicon
by Menci
The current implementation of virHostCPUGetInfo for macOS (__APPLE__)
reads "hw.cpufrequency" from sysctl, which is available only on x86_64
architecture.
On Apple Silicon ARM Macs, it's not available:
$ sysctl hw.cpufrequency # No output
$ arch -x86_64 sysctl hw.cpufrequency # Run with Rosetta 2
hw.cpufrequency: 2400000000
When running libvirtd on Apple Silicon, I got the error:
cannot obtain CPU freq: No such file or directory.
To fix it, we can calculate it with "hw.tbfrequency" and
"kern.clockrate" instead:
$ sysctl hw.tbfrequency
hw.tbfrequency: 24000000
$ sysctl kern.clockrate
kern.clockrate: { hz = 100, tick = 10000, tickadj = 0, profhz = 100, stathz = 100 }
The result value would be hw.tbfrequency * kern.clockrate.hz.

[PATCH 0/2] qemu_process: Start QEMU for caps probing more robustly
by Michal Privoznik
I'm not going to lie, my true motive is to be able to have a very small
bash wrapper that spawns QEMU under valgrind, e.g. like this:
#!/bin/bash
exec /usr/bin/valgrind --tool=memcheck --leak-check=full \
--track-fds=yes --log-file=/tmp/valgrind_qemu.log \
qemu-system-x86_64 "$@"
But if a malicious user provides slightly different script (see 2/2)
then they can starve libvirt worker pool. Hence, we have two reasons for
merging these.

[PATCH] qemu: Validate domain definition even on migration
by Michal Privoznik
When we are about to spawn QEMU, we validate the domain
definition against qemuCaps. Except when domain is/was already
running before (i.e. on incoming migration, snapshots, resume
from a file). However, especially on incoming migration it may
happen that the destination QEMU is different to the source
QEMU, e.g. the destination QEMU may have some devices disabled.
And we have a function that validates devices/features requested
in domain XML against the desired QEMU capabilities (aka
qemuCaps) - it's virDomainDefValidate() which calls
qemuValidateDomainDef() and qemuValidateDomainDeviceDef()
subsequently.
But the problem here is that the validation function is
explicitly skipped over in specific scenarios (like incoming
migration, restore from a snapshot or previously saved file).
This in turn means that we may spawn QEMU and request
device/features it doesn't support. When that happens QEMU fails
to load migration stream:
qemu-kvm: ... 'virtio-mem-pci' is not a valid device model name
(NB, while the example shows one particular device, the problem
is paramount)
This problem is easier to run into since we are slowly moving
validation from qemu_command.c into said validation functions.
The solution is simple: do the validation in all cases. And while
it may happen that users would be unable to migrate/restore a
guest due to a bug in our validator, spawning QEMU without
validation is worse (especially when you consider that users can
supply their own XMLs for migrate/restore operations - these were
never validated).

[libvirt PATCH v8 0/3] Ignore EPERM on implicit clearing of VF VLAN ID
by Dmitrii Shcherbakov
SmartNIC DPUs may not expose some privileged eswitch operations
to the hypervisor hosts. For example, this happens with Bluefield
devices running in the ECPF (default) mode [1] for security reasons. While
VF MAC address programming is possible via an RTM_SETLINK operation,
trying to set a VLAN ID in the same operation may fail with EPERM.
Specifically for the mlx5 driver this behavior was altered in the Linux
kernel upstream [2] to avoid getting EPERM when trying to program VLAN 0.
This may also get backported to older downstream kernels (e.g. [3]).
However, Libvirt could potentially handle this case gracefully without
needing a specific kernel version or depending on a specific driver fix.
In the kernel a relevant call chain may look like
do_setlink -> do_setvfinfo -> dev->netdev_ops->set_vf_vlan
which calls a driver-specific function like [4] eventually.
The equivalent ip link commands below provide an illustration:
1. This will work without an error:
sudo ip link set enp130s0f0 vf 2 mac de:ad:be:ef:ca:fe
2. Setting (or clearing) a VLAN will fail with EPERM:
sudo ip link set enp130s0f0 vf 2 vlan 0
RTNETLINK answers: Operation not permitted
3. This is what Libvirt attempts to do today when trying to clear a
VF VLAN at the same time as programming a VF MAC:
sudo ip link set enp130s0f0 vf 2 vlan 0 mac de:ad:be:ef:ca:fe
RTNETLINK answers: Operation not permitted
If setting an explicit VLAN ID results in an EPERM, clearing a VLAN
(setting a VLAN ID to 0) can be handled gracefully by ignoring the
EPERM error with the rationale being that if we cannot set this state
in the first place, we cannot clear it either.
Thus, virNetDevSetVfConfig is split into two distinct functions. If
clearing a VLAN ID fails with EPERM when clearing is implicit, the
error is simply ignored. For explicit clearing EPERM is still a
fatal error.
Both new functions rely virNetDevSendVfSetLinkRequest that implements
common functionality related to formatting a request, sending it and
handling error conditions and returns 0 or an error since in both cases
the payload is either NLMSG_DONE (no error) or NLMSG_ERROR where an
error message is needed by the caller to handle known cases
appropriately. This function allows the conditional code to be unit tested.
An alternative to this could be providing a higher level control plane
mechanism that would provide metadata about a device being remotely
managed in which case Libvirt would avoid trying to set or clear a
VLAN ID. This would be more complicated since other software (like Nova
in the OpenStack case) would have to annotate every guest device with an
attribute indicating whether a device is remotely managed or not based
on operator provided configuration so that Libvirt can act on this and
avoid VLAN programming.
