12d69ac03b tests: remove irrelevant assertions from test-aio
In these tests, the purpose of the initial calls to aio_poll and
g_main_context_iteration is simply to put the AioContext in a
known state; the return value of the function does not really
matter.  The next patch will change those return values; change
the assertions to a while loop which expresses the intention
better.

e4efd8a488 qemu-timer: initialize "timers_done_ev" to set
The normal value for the event is to be set.  If we do not do
this, pause_all_vcpus (through qemu_clock_enable) hangs unless
timerlist_run_timers has been run at least once for the timerlist.
This can happen with the following patches, that make aio_notify do
nothing most of the time.

9990069758 mirror: Speed up bitmap initial scanning
Limiting to sectors_per_chunk for each bdrv_is_allocated_above is slow,
because the underlying protocol driver would issue much more queries

4b7a6bf402 target-arm: kvm: Differentiate registers based on write-back levels
Some registers like the CNTVCT register should only be written to the
kernel as part of machine initialization or on vmload operations, but
never during runtime, as this can potentially make time go backwards or
create inconsistent time observations between VCPUs.

Introduce a list of registers that should not be written back at runtime
and check this list on syncing the register state to the KVM state.

625de449fc net: Flush queued packets when guest resumes
Since commit 6e99c63 "net/socket: Drop net_socket_can_send" and friends,
net queues need to be explicitly flushed after qemu_can_send_packet()
returns false, because the netdev side will disable the polling of fd.

This fixes the case of "cont" after "stop" (or migration).

80da311d81 net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packets
Convert partially summed packets to be fully checksummed.

In case csum offloaded packet, vmxnet3 implementation always passes an
RxCompDesc with the "Checksum calculated and found correct" notification
to the OS. This emulates the observed ESXi behavior.

Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and
place a fully computed checksum into the tcp/udp header. Otherwise, the
OS driver will receive a checksum-correct indication but with the actual
tcp/udp checksum field having just the pseudo header csum value.

If host OS performs forwarding, it will forward an incorrectly
checksummed packet.

The AHCI spec requires that the HBA sets the ICC bits to zero after the

This fixes delays with some OSs (e.g. OpenBSD) waiting for the ICC bits

The existing short PRDT test case does not transfer any data because the

This patch adds another short PRDT test case where the first sector can

Commit e0cf11f31c ("timer: Use a single
definition of NSEC_PER_SEC for the whole codebase") renamed
NANOSECONDS_PER_SECOND to NSEC_PER_SEC.

On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC.  This causes compiler warnings.

Let's use the old name instead.  It's longer but it doesn't clash.

virtio, vhost, pc fixes for 2.4

The only notable thing here is vhost-user multiqueue
revert. We'll work on making it stable in 2.5,
reverting now means we won't have to maintain
bug for bug compability forever.

f9d6dbf0bf virtio-net: remove virtio queues if the guest doesn't support multiqueue
commit da51a335 adds all queues in .realize(). But if the
guest doesn't support multiqueue, we forget to remove them. And
we cannot handle the ctrl vq corretly. The guest will hang.

38705bb57b virtio-net: Flush incoming queues when DRIVER_OK is being set
This patch fixes network hang after "stop" then "cont", while network
packets keep arriving.

Tested both manually (tap, host pinging guest) and with Jason's qtest
series (plus his "[PATCH 2.4] socket: pass correct size in
net_socket_send()" fix).

As virtio_net_set_status is called when guest driver is setting status
byte and when vm state is changing, it is a good opportunity to flush
queued packets.

This is necessary because during vm stop the backend (e.g. tap) would
stop rx processing after .can_receive returns false, until the queue is
explicitly flushed or purged.

The other interesting condition in .can_receive, virtio_queue_ready(),
is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition
is invalid queue index which doesn't need flushing.

Commit 032a74a1c0
("virtio-net: byteswap virtio-net header") breaks any layout by
requiring out_sg[0].iov_len >= n->guest_hdr_len. Fixing this by
copying header to temporary buffer if swap is needed, and then use
this buffer as part of out_sg.

d3462e378f crypto: avoid undefined behavior in nettle calls
Calling a function pointer that was cast from an incompatible function
results in undefined behavior.  'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper.  (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)

Having two different prototypes based on nettle version doesn't make
this solution any nicer.

c6742b14fe memory: fix refcount leak in memory_region_present
memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container".  While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.

The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that.  The RCU critical section
is needed anyway, because it protects as->current_map.
