O-Subject: [RHEL-AV-8.3.0 qemu-kvm PATCH 1/1] Drop bogus IPv6 messages
Bugzilla: 1867075

From: Ralf Haferkamp <rhafer@suse.com>
Drop IPv6 message shorter than what's mentioned in the payload
length header (+ the size of the IPv6 header). They're invalid an could
lead to data leakage in icmp6_send_echoreply().

Let wait_migration() return on failure (with the return value indicating
whether the migration was completed or has failed), so we can use it for
migrations that are expected to fail, too.

Reenable the -numa mem= syntax for old machine types, this is making
the downstream old machines behave in the same way as the upstream old
machines changed in upstream 32a354dc6c07d7.
Power already seems to have the change.

The auto_enable_numa_with_memdev flag automatically creates NUMA a
NUMA node in a case like:
-m 8G,maxmem=16G
but we need it to keep old machine types the same.
This is (mostly) done for upstream machine types in 195784a0cfad.
Power seems to have auto_enable_numa permenantly on anyway.

This migration parameter allows mapping block node names and bitmap
names to aliases for the purpose of block dirty bitmap migration.
This way, management tools can use different node and bitmap names on
the source and destination and pass the mapping of how bitmaps are to be
transferred to qemu (on the source, the destination, or even both with
arbitrary aliases in the migration stream).
While touching this code, fix a bug where bitmap names longer than 255
bytes would fail an assertion in qemu_put_counted_string().
