999f444a09 qemu: capabilities: Move setting of QEMU_CAPS_MACH_VIRT_GIC_VERSION to virQEMUCapsInitQMPBasicArch
Move it under AARCH 64, since it's a platform specific feature, thus it
will be removed from all other platforms.

Since virQEMUCapsInitQMPBasicArch is used in qemuxml2argv test to
initiate qemuCaps for tests with fake capabilities, all the tests gain
GIC support now.

QEMU_CAPS_MACHINE_PSERIES_RESIZE_HPT and

All supported qemu versions now have the flag so the test doesn't make

The flag setting will be moved to virQEMUCapsInitQMPBasicArch which will

b4cbdbe90b qemu: Formally deprecate support for qemu < 2.11
As of May 7 2021, rhel-8 will be out for two years, which means we no
longer have to support rhel-7 ancient qemu.

QEMU versions in our supported distros:

 RHEL-8: 2.12
 Debian Stable: 3.1
 OpenSuse LEAP 15.0 (SLES15 GA): 2.11
 OpenSuse LEAP 15.2: 4.2
 Ubuntu (Bionic): 2.11
 Ubuntu (Focal): 4.2

This means we can bring up the minimum supported version to 2.11.

e0c6691e78 meson: Declare GLIB_VERSION_* macros at configure
So far we have three places where glib version is recorded:
meson.build and then in config.h. The latter is so well hidden
that it's easy to miss when bumping minimal glib version in the
former. With a bit of python^Wmeson string magic
GLIB_VERSION_MIN_REQUIRED and GLIB_VERSION_MAX_ALLOWED macros can
be defined to match glib_version from meson.build.

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.

'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.
