Subject: [PATCH] RHEL: qemu_migration: Fix restoring memlock limit on
destination
Restoring memory locking limit on the destination host only makes sense
when migration succeeded as otherwise the QEMU process will be killed
anyway. Specifically if the migration fails because the process died,
touching the limit would produce rather unhelpful error message instead
of the real issue:
cannot get locked memory limit of process -1: No such file or
directory
This patch is RHEL-only caused by misplacing the call to
qemuDomainSetMaxMemLock when the "qemu_migration: Restore original
memory locking limit" upstream patch was backported to an older code
base.

Subject: [PATCH] conf: Move virDomainObj::originalMemlock into
qemuDomainObjPrivate
Since v1.3.0-90-gafbe1d4c56 the original value of memlock limit
is stored inside virDomainObj struct directly (under
originalMemlock member). This is needless because the value is
used only inside QEMU driver and thus can reside in
qemuDomainObjPrivate struct.

Subject: [PATCH] cpu_x86: Ignore enabled features for input models in
x86DecodeUseCandidate
While we don't want to aim for the shortest list of disabled features in
the baseline result (it would select a very old model), we want to do so
while looking at any of the input models for which we're trying to
compute a baseline CPU model. Given a set of input models, we always
want to take the least capable one of them (i.e., the one with shortest
list of disabled features) or a better model which is not one of the
input models.
So when considering an input model, we just check whether its list of
disabled features is shorter than the currently best one. When looking
at other models we check both enabled and disabled features while
penalizing disabled features as implemented by the previous patch.

Subject: [PATCH] nwfilter: fix crash when counting number of network filters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virNWFilterObjListNumOfNWFilters method iterates over the
driver->nwfilters, accessing virNWFilterObj instances. As such
it needs to be protected against concurrent modification of
the driver->nwfilters object.
This API allows unprivileged users to connect, so users with
read-only access to libvirt can cause a denial of service
crash if they are able to race with a call of virNWFilterUndefine.
Since network filters are usually statically defined, this is
considered a low severity problem.
This is assigned CVE-2022-0897.

applying it. This patch separates the code to apply a memory locking
limit to a new qemuDomainSetMaxMemLock helper for better reusability.

Older kernels did not support this sysctl, but they did not restrict
userfaultfd in any way so everything worked as if
vm.unprivileged_userfaultfd was set to 1. Thus we can safely ignore
errors when setting the value.

Subject: [PATCH] qemu: tpm: Get swtpm pid without binary validation
Access to /proc/[pid]/exe may be restricted in certain environments (e.g.
in containers) and any attempt to stat(2) or readlink(2) the file will
result in 'permission denied' error if the calling process does not have
CAP_SYS_PTRACE capability. According to proc(5) manpage:
Permission to dereference or read (readlink(2)) this symbolic link is
governed by a ptrace access mode PTRACE_MODE_READ_FSCREDS check; see
ptrace(2).
The binary validation in virPidFileReadPathIfAlive may fail with EACCES.
Therefore instead do only the check that the pidfile is locked by the
correct process. To ensure this is always the case the daemonization and
pidfile handling of the swtpm command is now controlled by libvirt.

Subject: [PATCH] qemuAgentGetDisks: Don't use virJSONValueObjectGetStringArray
for optional data
The 'dependencies' field in the return data may be missing in some
cases. Historically 'virJSONValueObjectGetStringArray' didn't report
error in such case, but later refactor (commit 043b50b948ef3c2 ) added
an error in order to use it in other places too.
Unfortunately this results in the error log being spammed with an
irrelevant error in case when qemuAgentGetDisks is invoked on a VM
running windows.
Replace the use of virJSONValueObjectGetStringArray by fetching the
array first and calling virJSONValueArrayToStringList only when we have
an array.
Fixes: 043b50b948ef3c2a4adf5fa32a93ec2589851ac6

Subject: [PATCH] qemuProcessReconnect: Don't build memory paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Let me take you on a short trip to history. A long time ago,
libvirt would configure all QEMUs to use $hugetlbfs/libvirt/qemu
for their hugepages setup. This was problematic, because it did
not allow enough separation between guests. Therefore in
v3.0.0-rc1~367 the path changed to a per-domain basis:
$hugetlbfs/libvirt/qemu/$domainShortName
And to help with migration on daemon restart a call to
qemuProcessBuildDestroyMemoryPaths() was added to
qemuProcessReconnect() (well, it was named
qemuProcessBuildDestroyHugepagesPath() back then, see
v3.10.0-rc1~174). This was desirable then, because the memory
hotplug code did not call the function, it simply assumes
per-domain paths to exist. But this changed in v3.5.0-rc1~92
after which the per-domain paths are created on memory hotplug
too.
Therefore, it's no longer necessary to create these paths in
qemuProcessReconnect(). They are created exactly when needed
(domain startup and memory hotplug).

Subject: [PATCH] qemu_namespace: Fix a corner case in
qemuDomainGetPreservedMounts()
When setting up namespace for QEMU we look at mount points under
/dev (like /dev/pts, /dev/mqueue/, etc.) because we want to
preserve those (which is done by moving them to a temp location,
unshare(), and then moving them back). We have a convenience
helper - qemuDomainGetPreservedMounts() - that processes the
mount table and (optionally) moves the other filesystems too.
This helper is also used when attempting to create a path in NS,
because the path, while starting with "/dev/" prefix, may
actually lead to one of those filesystems that we preserved.
And here comes the corner case: while we require the parent mount
table to be in shared mode (equivalent of `mount --make-rshared /'),
these mount events propagate iff the target path exist inside the
slave mount table (= QEMU's private namespace). And since we
create only a subset of /dev nodes, well, that assumption is not
always the case.
For instance, assume that a domain is already running, no
hugepages were configured for it nor any hugetlbfs is mounted.
Now, when a hugetlbfs is mounted into '/dev/hugepages', this is
propagated into the QEMU's namespace, but since the target dir
does not exist in the private /dev, the FS is not mounted in the
namespace.
Fortunately, this difference between namespaces is visible when
comparing /proc/mounts and /proc/$PID/mounts (where PID is the
QEMU's PID). Therefore, if possible we should look at the latter.

Subject: [PATCH] qemu_namespace: Tolerate missing ACLs when creating a path in
namespace
When creating a path in a domain's mount namespace we try to set
ACLs on it, so that it's a verbatim copy of the path in parent's
namespace. The ACLs are queried upfront (by
qemuNamespaceMknodItemInit()) but this is fault tolerant so the
pointer to ACLs might be NULL (meaning no ACLs were queried, for
instance because the underlying filesystem does not support
them). But then we take this NULL and pass it to virFileSetACLs()
which immediately returns an error because NULL is invalid value.
Mimic what we do with SELinux label - only set ACLs if they are
non-NULL which includes symlinks.

Subject: [PATCH] qemu_process: Don't require a hugetlbfs mount for memfd
The aim of qemuProcessNeedHugepagesPath() is to determine whether
a hugetlbfs mount point is required for given domain (as in
whether qemuBuildMemoryBackendProps() picks up
memory-backend-file pointing to a hugetlbfs mount point). Well,
when domain is configured to use memfd backend then that
condition can never be true. Therefore, skip creating domain's
private path under hugetlbfs mount points.

Subject: [PATCH] qemu_process.c: Propagate hugetlbfs mounts on reconnect
When reconnecting to a running QEMU process, we construct the
per-domain path in all hugetlbfs mounts. This is a relict from
the past (v3.4.0-100-g5b24d25062) where we switched to a
per-domain path and we want to create those paths when libvirtd
restarts on upgrade.
And with namespaces enabled there is one corner case where the
path is not created. In fact an error is reported and the
reconnect fails. Ideally, all mount events are propagated into
the QEMU's namespace. And they probably are, except when the
target path does not exist inside the namespace. Now, it's pretty
common for users to mount hugetlbfs under /dev (e.g.
/dev/hugepages), but if domain is started without hugepages (or
more specifically - private hugetlbfs path wasn't created on
domain startup), then the reconnect code tries to create it.
But it fails to do so, well, it fails to set seclabels on the
path because, because the path does not exist in the private
namespace. And it doesn't exist because we specifically create
only a subset of all possible /dev nodes. Therefore, the mount
event, whilst propagated, is not successful and hence the
filesystem is not mounted. We have to do it ourselves.
If hugetlbfs is mount anywhere else there's no problem and this
is effectively a dead code.

Subject: [PATCH] qemu_tpm: Do async IO when starting swtpm emulator
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When vTPM is secured via virSecret libvirt passes the secret
value via an FD when swtpm is started (arguments --key and
--migration-key). The writing of the secret into the FDs is
handled via virCommand, specifically qemu_tpm calls
virCommandSetSendBuffer()) and then virCommandRunAsync() spawns a
thread to handle writing into the FD via
virCommandDoAsyncIOHelper. But the thread is not created unless
VIR_EXEC_ASYNC_IO flag is set, which it isn't. In order to fix
it, virCommandDoAsyncIO() must be called.
The credit goes to Marc-André Lureau
<marcandre.lureau@redhat.com> who has done all the debugging and
proposed fix in the bugzilla.

Subject: [PATCH] virDomainDiskDefValidateStartupPolicy: Validate disk type
better
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Our startup policy checkers work only for local paths, so disk sources
such as NVMe, or vhost-user can't be used with startup policy.
Unfortunately the validation did not catch these cases. Fix it.

Subject: [PATCH] virDomainDiskTranslateSourcePool: Fix check of
'startupPolicy' definition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The check was historically done only for _TYPE_VOLUME disks, but
refactors to allow _TYPE_VOLUME disks in the backing chain caused a
regression where we'd reject startupPolicy also for _TYPE_BLOCK disks
which historically worked well.
Fix it by using the 'virDomainDiskDefValidateStartupPolicy' helper and
use it only when the top level image is a _TYPE_VOLUME as in other cases
it was already validated. This also allows _TYPE_BLOCK volumes to use
startup policy.
