241c22a9a5 virnetdevbridge: Ignore EEXIST when adding an entry to fdb
When updating entries in a bridge forwarding database (i.e., when
macTableManager='libvirt' is configured for the bridge), we may end up
in a situation when the entry we want to add is already present. Let's
just ignore the error in such a case.

This fixes an error to resume a domain when fdb entries were not
properly removed when the domain was paused:

    virsh # resume test
    error: Failed to resume domain test
    error: error adding fdb entry for vnet2: File exists

For some reason, fdb entries are only removed when libvirt explicitly
stops CPUs, but nothing happens when we just get STOP event from QEMU.
An alternative approach would be to make sure we always remove the
entries regardless on why a domain was paused (e.g., during migration),
but that would be a significantly more disruptive change with possible
side effects.

6dca93e4bc conf: Fix heap corruption when hot-adding a lease
Commit 28a8699316 ( v6.9.0-179-g28a8699316 ) incorrectly replaced
VIR_EXPAND_N by g_renew.

VIR_EXPAND_N has these two extra effects apart from reallocating memory:

1) The newly allocated memory is zeroed out
2) The number of elements in the array which is passed to VIR_EXPAND_N
   is increased.

This comes into play when used with virDomainLeaseInsertPreAlloced,
which expects that the array element count already includes the space
for the added 'lease', by plainly just assigning to
'leases[nleases - 1]'

Since g_renew does not increase the number of elements in the array
any existing code which calls virDomainLeaseInsertPreAlloced thus either
overwrites a lease definition or corrupts the heap if there are no
leases to start with.

To preserve existing functionality we revert the code back to using
VIR_EXPAND_N which at this point doesn't return any value, so other
commits don't need to be reverted.

59543dfad6 qemuDomainBlockJobAbort: Don't use 'job-cancel' instead of 'block-job-cancel'
'block-job-cancel' has one very important semantic difference to
'job-cancel', docummented in qemu as:

  Note that if you issue 'block-job-cancel' after 'drive-mirror' has indicated
  (via the event BLOCK_JOB_READY) that the source and destination are
  synchronized, then the event triggered by this command changes to
  BLOCK_JOB_COMPLETED, to indicate that the mirroring has ended and the
  destination now has a point-in-time copy tied to the time of the cancellation.

Since libvirt advertises the block copy job as having the synchronous
abort feature we must not use 'job-cancel' here.

Commit 518be41aaa refactored qemuMigrationCookieNBDXMLFormat to use
virXMLFormatElement which in comparison to the previous code doesn't

Unfortunately some crusty bits of our migration code use questionable
logic to assert use of the old-style storage migration parameters which
breaks if no disks are being migrated and the <nbd/> element is not
present.

While later patches will fix the code, re-instate formatting of empty
<nbd/> for increased compatibility.

1051c23b51 lxc: Let the driver detect CGroups earlier
This is the bug I'm facing. I deliberately configured a container
so that the source of a <filesystem/> to passthrough doesn't
exist. The start fails with:

  lxcContainerPivotRoot:669 : Failed to create /non-existent/path/.oldroot: Permission denied

which is expected. But what is NOT expected is that CGroup
hierarchy is left behind. This is because the controller sets up
the CGroup hierarchy, user namespace, moves interfaces, etc. and
finally checks whether container setup (done in a separate
process) succeeded. Only after all this the error is propagated
to the LXC driver. The driver aborts the startup and tries to
perform the cleanup, but this is missing CGroups because those
weren't detected yet.

Ideally, whenever a function fails, it tries to unroll back so
that is has no artifacts left behind (look at all those frees/FD
closes/etc. at end of functions). But with CGroups it is
different - the controller process can't clean up after itself,
because it is still running inside that CGroup.

Therefore, what we have to do is to let the driver detect CGroups
as soon as they are created, and proceed with controller
execution only after that.

81e770c2f1 qemu: blockjob: Transition into 'ready' state only from expected states
In certain rare occasions qemu can transition a block job which was
already 'ready' into 'standby' and then back. If this happens in the
following order libvirt will get confused about the actual job state:

1) the block copy job is 'ready' (job->state == QEMU_BLOCKJOB_STATE_READY)

2) user calls qemuDomainBlockJobAbort with VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT
   flag but without VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC

3) the block job is switched to synchronous event handling

4) the block job blips to 'standby' and back to 'ready', the event is
   not processed since the blockjob is in sync mode for now

5) qemuDomainBlockJobPivot is called:
    5.1) 'job-complete' QMP command is issued
    5.2) job->state is set to QEMU_BLOCKJOB_STATE_PIVOTING

6) code for synchronous-wait for the job completion in qemuDomainBlockJobAbort
   is invoked

7) the waiting loop calls qemuBlockJobUpdate:

    7.1) job->newstate is QEMU_BLOCKJOB_STATE_READY due to 4)
    7.2) qemuBlockJobEventProcess is called
    7.3) the handler for QEMU_BLOCKJOB_STATE_READY overwrites
         job->state from QEMU_BLOCKJOB_STATE_PIVOTING to QEMU_BLOCKJOB_STATE_READY

8) qemuDomainBlockJobAbort is looking for a finished job, so waits again

9) qemu finishes the blockjob and transitions it into 'concluded' state

10) qemuBlockJobUpdate is triggered again, this time finalizing the job.
    10.1) job->newstate is = QEMU_BLOCKJOB_STATE_CONCLUDED
          job->state is = QEMU_BLOCKJOB_STATE_READY
    10.2) qemuBlockJobEventProcessConcluded is called, the function
          checks whether there was an error with the blockjob. Since
          there was no error job->newstate becomes
          QEMU_BLOCKJOB_STATE_COMPLETED.
    10.3) qemuBlockJobEventProcessConcludedTransition selects the action
          for the appropriate block job type where we have:

    case QEMU_BLOCKJOB_TYPE_COPY:
        if (job->state == QEMU_BLOCKJOB_STATE_PIVOTING && success)
            qemuBlockJobProcessEventConcludedCopyPivot(driver, vm, job, asyncJob);
        else
            qemuBlockJobProcessEventConcludedCopyAbort(driver, vm, job, asyncJob);
        break;

          Since job->state is QEMU_BLOCKJOB_STATE_READY,
          qemuBlockJobProcessEventConcludedCopyAbort is called.

This patch forbids transitions to QEMU_BLOCKJOB_STATE_READY if the
previous job state isn't QEMU_BLOCKJOB_STATE_RUNNING or
QEMU_BLOCKJOB_STATE_NEW.

45a61cbf68 util: xml: Fix confusing semantics of VIR_XML_PROP_OPTIONAL flag
The new enum helpers use a set of flags to modify their behaviour, but
the declared set of flags is semantically confusing:

 typedef enum {
     VIR_XML_PROP_OPTIONAL = 0, /* Attribute may be absent */
     VIR_XML_PROP_REQUIRED = 1 << 0, /* Attribute may not be absent */

Since VIR_XML_PROP_OPTIONAL is declared as 0 any other flag shadows it
and makes it impossible to detect. The functions are not able to detect
a semantic nonsense of VIR_XML_PROP_OPTIONAL | VIR_XML_PROP_REQUIRED and
it's a perfectly valid statement for the compilers.

In general having two flags to do the same boolean don't make sense and
the implementation doesn't fix any shortcomings either.

To prevent mistakes, rename VIR_XML_PROP_OPTIONAL to VIR_XML_PROP_NONE,
so that there's always an enum value used with the calls but it doesn't
imply that the flag makes the property optional when the actual value is
0.

These are mostly fine except for the one that translates both "start"

global translator that handles all the mdevctl command differences and

This is not a 1:1 mapping to mdevctl commands because mdevctl doesn't

starting a pre-defined device as well as for creating and starting a new

these as separate commands. When we need to actually execute mdevctl,
the 'create' command will be translated into the appropriate 'mdevctl

instance out of it"

"create" in libvirt most of the time means - "take and XML description,
make an object out of it and use it to create an instance"

This gets confusing with mdevctl which uses "start" for both. So, this
patch proposes to use virMdevctlStart in cases where from libvirt's POV
we're starting a defined device (unlike mdevctl). Similarly, use
virMdevctlCreate in scenarios where XML description is passed to
libvirt and a transient device is supposed to be created.

14085ef98d nodedev: avoid use of VIR_ERR_NO_* errors internally
These errors are demoted to debug statements[1] since they're only
intended to be used as return values for public APIs.  This makes it
difficult to debug the problem when something goes wrong since no error
message is logged. Switch instead to VIR_ERR_INTERNAL_ERROR so that the
error is logged as expected.

[1] See the implementation of daemonErrorLogFilter() for details:

ea7d0ca37c vircgroup: Fix virCgroupKillRecursive() wrt nested controllers
I've encountered the following bug, but only on Gentoo with
systemd and CGroupsV2. I've started an LXC container successfully
but destroying it reported the following error:

  error: Failed to destroy domain 'amd64'
  error: internal error: failed to get cgroup backend for 'pathOfController'

Debugging showed, that CGroup hierarchy is full of surprises:

/sys/fs/cgroup/machine.slice/machine-lxc\x2d861\x2damd64.scope/
└── libvirt
    ├── dev-hugepages.mount
    ├── dev-mqueue.mount
    ├── init.scope
    ├── sys-fs-fuse-connections.mount
    ├── sys-kernel-config.mount
    ├── sys-kernel-debug.mount
    ├── sys-kernel-tracing.mount
    ├── system.slice
    │   ├── console-getty.service
    │   ├── dbus.service
    │   ├── system-getty.slice
    │   ├── system-modprobe.slice
    │   ├── systemd-journald.service
    │   ├── systemd-logind.service
    │   └── tmp.mount
    └── user.slice

For comparison, here's the same container on recent Rawhide:

/sys/fs/cgroup/machine.slice/machine-lxc\x2d13550\x2damd64.scope/
└── libvirt

Anyway, those nested directories should not be a problem, because
virCgroupKillRecursiveInternal() removes them recursively, right?
Sort of. The function really does remove nested directories, but
it assumes that every directory has the same controller as the
rest. Just take a look at virCgroupV2KillRecursive() - it gets
'Any' controller (the first one it found in ".scope") and then
passes it to virCgroupKillRecursiveInternal().

This assumption is not true though. The controllers found in
".scope" are the following:

  cpuset cpu io memory pids

while "libvirt" has fewer:

  cpuset cpu io memory

Up until now it's not problem, because of how we order
controllers internally - "cpu" is the first and thus picking
"Any" controller returns just that. But the rest of directories
has no controllers, their "cgroup.controllers" is just empty.

What fixes the bug is dropping @controller argument from
virCgroupKillRecursiveInternal() and letting each iteration work
pick its own controller.

12850ed257 nodedev: refactor virMediatedDeviceGetIOMMUGroupNum()
Currently virMediatedDeviceGetIOMMUGroupDev() looks up the iommu group
number and uses that to construct a path to the iommu group device.
virMediatedDeviceGetIOMMUGroupNum() then uses that device path and takes
the basename to get the group number. That's unnecessary extra string
manipulation for *GroupNum(). Reverse the implementations and make
*GroupDev() call *GroupNum().

07497fc6da vircgroupv2devices: refactor virCgroupV2DevicesRemoveProg
When running on systemd host the cgroup itself is removed by machined
so when we reach this code the directory no longer exist. If libvirtd
was running the whole time between starting and destroying VM the
detection is skipped because we still have both FD in memory. But if
libvirtd was restarted and no operation requiring cgroup devices
executed the FDs would be 0 and libvirt would try to detect them using
the cgroup directory. This results in reporting following errors:

    libvirtd[955]: unable to open '/sys/fs/cgroup/machine.slice/machine-qemu\x2d1\x2dguest.scope/': No such file or directory
    libvirtd[955]: Failed to remove cgroup for guest

When running on non-systemd host where we handle cgroups manually this
would not happen.

When destroying VM it is not necessary to detect the BPF prog and map
because the following code only closes the FDs without doing anything
else. We could run code that would try to detach the BPF prog from the
cgroup but that is not necessary as well. If the cgroup is removed and
there is no other FD open to the prog kernel will cleanup the prog and
map eventually.

6960a895ab vircgroupv2: properly free BPF prog and map FDs
When nested cgroup was introduced it did not properly free file
descriptors for BPF prog and map. With nested cgroups we create the BPF
bits in the nested cgroup instead of the VM root cgroup.

This would leak the FDs which would be the last reference to the prog
and map so kernel would not remove the resources as well. It would only
happen once libvirtd process exits.

8674faaf32 nodedev: Don't fail device enumeration if MDEVCTL is missing
After all devices were enumerated, the enumeration thread call
nodeDeviceUpdateMediatedDevices() to refresh the state of
mediated devices. This means that 'mdevctl' will be executed. But
it may be missing on some systems (e.g. mine) in which case we
should just skip the update of mdevs instead of failing whole
device enumeration.

54d97f020b nodedev: Mark device initialization complete even in case of an error
To speed up nodedev driver initialization, the device enumeration
is done in a separate thread. Once finished, the thread sets a
boolean variable that allows public APIs to be called (instead of
waiting for the thread to finish).

However, if there's an error in the device enumeration thread
then the control jumps over at the 'error' label and the boolean
is never set. This means, that any virNodeDev*() API is stuck
forever. Mark the initialization as complete (the thread is
quitting anyway) and let the APIs proceed.

77a13eb9ac nodedev: Wait for device initialization in all public API callbacks
Although I have not experienced this in real life, there is a
possible race condition when creating new device, getting its XML
or parent or listing its capabilities.  If the nodedev driver is
still enumerating devices (in a separate thread) and one of
virNodeDeviceGetXMLDesc(), virNodeDeviceGetParent(),
virNodeDeviceNumOfCaps(), virNodeDeviceListCaps() or
virNodeDeviceCreate() is called then it can lead to spurious
results because the device enumeration thread is removing devices
from or adding them to the internal list of devices (among with
their states).

Therefore, wait for things to settle down before proceeding with
any of the APIs.

5b56a288ca nodedev: Signal initCond with driver locked
This is more academic dispute than a real bug, but this is taken
from pthread_cond_broadcast(3p) man:

  The pthread_cond_broadcast() or pthread_cond_signal() functions
  may be called by a thread whether or not it currently owns the
  mutex that threads calling pthread_cond_wait() or
  pthread_cond_timedwait() have associated with the condition
  variable during their waits; however, if predictable scheduling
  behavior is required, then that mutex shall be locked by the
  thread calling pthread_cond_broadcast() or
  pthread_cond_signal().

Therefore, broadcast the initCond while the nodedev driver is
still locked.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:
