Subject: Revert "vnc: allow fall back to RAW encoding"
Git-commit: 0780ec7be82dd4781e9fd216b5d99a125882ff5a
This reverts commit de3f7de7f4e257ce44cdabb90f5f17ee99624557.
Remove VNC optimization to reencode framebuffer update as raw if it's
smaller than the default encoding.
QEMU's implementation was naive and didn't account for the ZLIB z_stream
mutating with each compression. Because of the mutation, simply
resetting the output buffer's offset wasn't sufficient to "rewind" the
operation. The mutated z_stream would generate future zlib blocks which
referred to symbols in past blocks which weren't sent. This would lead
to artifacting.
Considering that ZRLE is never larger than raw and even though ZLIB can
occasionally be fractionally larger than raw, the overhead of
implementing this optimization correctly isn't worth it.

Subject: hw/i386: disable smbus migration for xenfv
Git-commit: 0000000000000000000000000000000000000000
References: bsc#1159755
With commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea a new member
smbus_no_migration_support was added, and enabled in two places.
With commit 4ab2f2a8aabfea95cc53c64e13b3f67960b27fdf the vmstate_acpi
got new elements, which are conditionally filled. As a result, an
incoming migration expected smbus related data unless smbus migration
was disabled for a given MachineClass.
Since commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea forgot to handle
xenfv, live migration to receiving hosts using qemu-4.0 and later is broken.
Therefore this patch must be applied to stable-4.x as well.

xenfv, not xenpv, as Olaf indicated in followup email]

Subject: hw/i386/pc: fix regression in parsing vga cmdline parameter
Git-commit: a88c40f02ace88f09b2a85a64831b277b2ebc88c
When the 'vga=' parameter is succeeded by another parameter, QEMU 4.2.0
would refuse to start with a rather cryptic message:
$ qemu-system-x86_64 -kernel /boot/vmlinuz-linux -append 'vga=792 quiet'
qemu: can't parse 'vga' parameter: Invalid argument
It was not clear whether this applied to the '-vga std' parameter or the
'-append' one. Fix the parsing regression and clarify the error.

Subject: iscsi: Cap block count from GET LBA STATUS (CVE-2020-1711)
Git-commit: 693fd2acdf14dd86c0bf852610f1c2cca80a74dc
When querying an iSCSI server for the provisioning status of blocks (via
GET LBA STATUS), Qemu only validates that the response descriptor zero's
LBA matches the one requested. Given the SCSI spec allows servers to
respond with the status of blocks beyond the end of the LUN, Qemu may
have its heap corrupted by clearing/setting too many bits at the end of
its allocmap for the LUN.
A malicious guest in control of the iSCSI server could carefully program
Qemu's heap (by selectively setting the bitmap) and then smash it.
This limits the number of bits that iscsi_co_block_status() will try to
update in the allocmap so it can't overflow the bitmap.

From: Laurent Vivier <lvivier@redhat.com>

Subject: migration-test: ppc64: fix FORTH test program
Git-commit: 16c5c6928ff53bd95e6504301ef6c285501531e7
Commit e51e711b1bef has moved the initialization of start_address and
end_address after the definition of the command line argument,
where the nvramrc is initialized, and thus the loop is between 0 and 0
rather than 1 MiB and 100 MiB.
It doesn't affect the result of the test if all the tests are run in
sequence because the two first tests don't run the loop, so the
values are correctly initialized when we actually need them.
But it hangs when we ask to run only one test, for instance:
QTEST_QEMU_BINARY=ppc64-softmmu/qemu-system-ppc64 \
tests/migration-test -m=quick -p /ppc64/migration/validate_uuid_error
Fixes: e51e711b1bef ("tests/migration: Add migration-test header file")

Subject: runstate: ignore finishmigrate -> prelaunch transition
Git-commit: ddad81bd28de665475a87693a93e6cf5d6fd8bab
Commit 1bd71dce4bf2 tries to prevent a finishmigrate -> prelaunch
transition by exiting at the beginning of the main_loop_should_exit()
function if the state is already finishmigrate.
As the finishmigrate state is set in the migration thread it can
happen concurrently to the function. The migration thread and the
function are normally protected by the iothread mutex and thus the
state should no evolve between the start of the function and its end.
Unfortunately during the function life the lock is released by
pause_all_vcpus() just before the point we need to be sure we are
not in finishmigrate state and if the migration thread is waiting
for the lock it will take the opportunity to change the state
to finishmigrate.
The only way to be sure we are not in the finishmigrate state when
we need is to check the state after the pause_all_vcpus() function.
Fixes: 1bd71dce4bf2 ("runstate: ignore exit request in finish migrate state")

Subject: s390x: adapter routes error handling
Git-commit: 3c5fd8074335c67777d9391b84f97070c35d9c63
If the kernel irqchip has been disabled, we don't want the
{add,release}_adapter_routes routines to call any kvm_irqchip_*
interfaces, as they may rely on an irqchip actually having been
created. Just take a quick exit in that case instead. If you are
trying to use irqfd without a kernel irqchip, we will fail with
an error.
Also initialize routes->gsi[] with -1 in the virtio-ccw handling,
to make sure we don't trip over other errors, either. (Nobody
else uses the gsi array in that structure.)

Subject: target/arm: Return correct IL bit in merge_syn_data_abort
Git-commit: 30d544839e278dc76017b9a42990c41e84a34377
The IL bit is set for 32-bit instructions, thus passing false
with the is_16bit parameter to syn_data_abort_with_iss() makes
a syn mask that always has the IL bit set.
Pass is_16bit as true to make the initial syn mask have IL=0,
so that the final IL value comes from or'ing template_syn.

Subject: target/i386: kvm: initialize feature MSRs very early
Git-commit: 420ae1fc51c99abfd03b1c590f55617edd2a2bed
Some read-only MSRs affect the behavior of ioctls such as
KVM_SET_NESTED_STATE. We can initialize them once and for all
right after the CPU is realized, since they will never be modified
by the guest.

Subject: vnc: prioritize ZRLE compression over ZLIB
Git-commit: 557ba0e57200014bd4f453f6516f02b61bdfc782
In my investigation, ZRLE always compresses better than ZLIB so
prioritize ZRLE over ZLIB, even if the client hints that ZLIB is
preferred.
zlib buffer is always reset in zrle_compress_data(), so using offset to
calculate next_out and avail_out is useless.
