4aedda25e8 virtio: reset device on bad guest index in virtio_load()
If we find a queue with an inconsistent guest index value, explicitly mark the
device as needing a reset - and broken - via virtio_error().

There's at least one driver implementation - the virtio-win NetKVM driver - that
is able to handle a VIRTIO_CONFIG_S_NEEDS_RESET notification and successfully
restore the device to a working state. Other implementations do not correctly
handle this, but as the VQ is not in a functional state anyway, this is still
worth doing.

5039caf3c4 memory: Add IOMMUTLBEvent
This way we can tell between regular IOMMUTLBEntry (entry of IOMMU
hardware) and notifications.

In the notifications, we set explicitly if it is a MAPs or an UNMAP,
instead of trusting in entry permissions to differentiate them.

81ee17aa46 vhost-user-scsi: Fix memleaks in vus_proc_req()
The 'elem' is allocated memory in vu_queue_pop(), and its memory should be
freed in all error branches after vu_queue_pop().
In addition, in order to free the 'elem' memory outside of while(1) loop, move
the definition of 'elem' to the beginning of vus_proc_req().

8132122889 ide: atapi: assert that the buffer pointer is in range
A case was reported where s->io_buffer_index can be out of range.
The report skimped on the details but it seems to be triggered
by s->lba == -1 on the READ/READ CD paths (e.g. by sending an
ATAPI command with LBA = 0xFFFFFFFF).  For now paper over it
with assertions.  The first one ensures that there is no overflow
when incrementing s->io_buffer_index, the second checks for the
buffer overrun.

Note that the buffer overrun is only a read, so I am not sure
if the assertion failure is actually less harmful than the overrun.

An out-of-bounds access issue was found in the SLIRP user networking
implementation of QEMU. It could occur while processing ARP/NCSI
packets, if the packet length was shorter than required to accommodate
respective protocol headers and payload. A privileged guest user may use
this flaw to potentially leak host information bytes.

introduced a regression blocking bus addresses > 0x1f or higher.
Legal bus numbers go up to 0xff.

82d469e139 ppc patch queue for 2020-11-24
One final update for qemu-5.2, implementing an instruction that we
 already should have, given the ISA version we claim to support.  Sorry
 for the lateness, I've been on holiday.
 
 This isn't a regression, obviously, so if it misses qemu-5.2 it's not
 a disaster, but it would be nice to have.  The risk is low that it
 would break any existing instructions.

558f5c42ef tests/9pfs: Mark "local" tests as "slow"
The "local" tests can fail on some automated build systems as
reported here:

https://lists.nongnu.org/archive/html/qemu-devel/2020-11/msg05510.html

This will need to be investigated and addressed later. Let's go for a
workaround in the meantime : mark the "local" tests as "slow" so that
they aren't executed with a simple "make check" like in the case above.

c8bf9a9169 qcow2: Fix corruption on write_zeroes with MAY_UNMAP
Commit 205fa50750 ("qcow2: Add subcluster support to zero_in_l2_slice()")
introduced a subtle change to code in zero_in_l2_slice:

It swapped the order of

1. qcow2_cache_entry_mark_dirty(s->l2_table_cache, l2_slice);
2. set_l2_entry(s, l2_slice, l2_index + i, QCOW_OFLAG_ZERO);
3. qcow2_free_any_clusters(bs, old_offset, 1, QCOW2_DISCARD_REQUEST);

To

1. qcow2_cache_entry_mark_dirty(s->l2_table_cache, l2_slice);
2. qcow2_free_any_clusters(bs, old_offset, 1, QCOW2_DISCARD_REQUEST);
3. set_l2_entry(s, l2_slice, l2_index + i, QCOW_OFLAG_ZERO);

It seems harmless, however the call to qcow2_free_any_clusters can
trigger a cache flush which can mark the L2 table as clean, and
assuming that this was the last write to it, a stale version of it
will remain on the disk.

Now we have a valid L2 entry pointing to a freed cluster. Oops.

d2abc563e4 net: purge queued rx packets on queue deletion
https://bugzilla.redhat.com/show_bug.cgi?id=1829272
When deleting queue pair, purge pending RX packets if any.
Example of problematic flow:
1. Bring up q35 VM with tap (vhost off) and virtio-net or e1000e
2. Run ping flood to the VM NIC ( 1 ms interval)
3. Hot unplug the NIC device (device_del)
   During unplug process one or more packets come, the NIC
   can't receive, tap disables read_poll
4. Hot plug the device (device_add) with the same netdev
The tap stays with read_poll disabled and does not receive
any packets anymore (tap_send never triggered)
