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: aio-wait: delegate polling of main AioContext if BQL not held
Git-commit: 3c18a92dc4b55ca8cc37a755ed119f11c0f34099
Any thread that is not a iothread returns NULL for qemu_get_current_aio_context().
As a result, it would also return true for
in_aio_context_home_thread(qemu_get_aio_context()), causing
AIO_WAIT_WHILE to invoke aio_poll() directly. This is incorrect
if the BQL is not held, because aio_poll() does not expect to
run concurrently from multiple threads, and it can actually
happen when savevm writes to the vmstate file from the
migration thread.
Therefore, restrict in_aio_context_home_thread to return true
for the main AioContext only if the BQL is held.
The function is moved to aio-wait.h because it is mostly used
there and to avoid a circular reference between main-loop.h
and block/aio.h.

Subject: arm/arm-powerctl: set NSACR.{CP11, CP10} bits in arm_set_cpu_on()
Git-commit: 0c7f8c43daf6556078e51de98aa13f069e505985
This change ensures that the FPU can be accessed in Non-Secure mode
when the CPU core is reset using the arm_set_cpu_on() function call.
The NSACR.{CP11,CP10} bits define the exception level required to
access the FPU in Non-Secure mode. Without these bits set, the CPU
will give an undefined exception trap on the first FPU access for the
secondary cores under Linux.
This is necessary because in this power-control codepath QEMU
is effectively emulating a bit of EL3 firmware, and has to set
the CPU up as the EL3 firmware would.

Subject: async: use explicit memory barriers
Git-commit: 5710a3e09f9b85801e5ce70797a4a511e5fc9e2c
When using C11 atomics, non-seqcst reads and writes do not participate
in the total order of seqcst operations. In util/async.c and util/aio-posix.c,
in particular, the pattern that we use
write ctx->notify_me write bh->scheduled
read bh->scheduled read ctx->notify_me
if !bh->scheduled, sleep if ctx->notify_me, notify
needs to use seqcst operations for both the write and the read. In
general this is something that we do not want, because there can be
many sources that are polled in addition to bottom halves. The
alternative is to place a seqcst memory barrier between the write
and the read. This also comes with a disadvantage, in that the
memory barrier is implicit on strongly-ordered architectures and
it wastes a few dozen clock cycles.
Fortunately, ctx->notify_me is never written concurrently by two
threads, so we can assert that and relax the writes to ctx->notify_me.
The resulting solution works and performs well on both aarch64 and x86.
Note that the atomic_set/atomic_read combination is not an atomic
read-modify-write, and therefore it is even weaker than C11 ATOMIC_RELAXED;
on x86, ATOMIC_RELAXED compiles to a locked operation.

References: bsc#117037, CVE-2020-11869
In some corner cases (that never happen during normal operation but a
malicious guest could program wrong values) pixman functions were
called with parameters that result in a crash. Fix this and add more
checks to disallow such cases.

Git-commit: 503ca1262bab2c11c533a4816d1ff4297d4f58a6
When dropping backup-top, we need to drain the node before freeing the
BlockCopyState. Otherwise, requests may still be in flight and then the
assertion in shres_destroy() will fail.
(This becomes visible in intermittent failure of 056.)

Subject: blkdebug: Allow taking/unsharing permissions
Git-commit: 69c6449ff10fe4e3219e960549307096d5366bd0
Sometimes it is useful to be able to add a node to the block graph that
takes or unshare a certain set of permissions for debugging purposes.
This patch adds this capability to blkdebug.
(Note that you cannot make blkdebug release or share permissions that it
needs to take or cannot share, because this might result in assertion
failures in the block layer. But if the blkdebug node has no parents,
it will not take any permissions and share everything by default, so you
can then freely choose what permissions to take and share.)

Subject: block: Activate recursively even for already active nodes
Git-commit: 7bb4941ace471fc7dd6ded4749b95b9622baa6ed
bdrv_invalidate_cache_all() assumes that all nodes in a given subtree
are either active or inactive when it starts. Therefore, as soon as it
arrives at an already active node, it stops.
However, this assumption is wrong. For example, it's possible to take a
snapshot of an inactive node, which results in an active overlay over an
inactive backing file. The active overlay is probably also the root node
of an inactive BlockBackend (blk->disable_perm == true).
In this case, bdrv_invalidate_cache_all() does not need to do anything
to activate the overlay node, but it still needs to recurse into the
children and the parents to make sure that after returning success,
really everything is activated.

Git-commit: 7b1d9c4df0603fbc526226a9c5ef91118aa6c957
We need some way to correlate QAPI BlockPermission values with
BLK_PERM_* flags. We could:
(1) have the same order in the QAPI definition as the the BLK_PERM_*
flags are in LSb-first order. However, then there is no guarantee
that they actually match (e.g. when someone modifies the QAPI schema
without thinking of the BLK_PERM_* definitions).
We could add static assertions, but these would break what’s good
about this solution, namely its simplicity.
(2) define the BLK_PERM_* flags based on the BlockPermission values.
But this way whenever someone were to modify the QAPI order
(perfectly sensible in theory), the BLK_PERM_* values would change.
Because these values are used for file locking, this might break
file locking between different qemu versions.
Therefore, go the slightly more cumbersome way: Add a function to
translate from the QAPI constants to the BLK_PERM_* flags.

Subject: block: Fix VM size field width in snapshot dump
Git-commit: 804359b8b90f76d9d8fbe8d85a6544b68f107f10
When printing the snapshot list (e.g. with qemu-img snapshot -l), the VM
size field is only seven characters wide. As of de38b5005e9, this is
not necessarily sufficient: We generally print three digits, and this
may require a decimal point. Also, the unit field grew from something
as plain as "M" to " MiB". This means that number and unit may take up
eight characters in total; but we also want spaces in front.
Considering previously the maximum width was four characters and the
field width was chosen to be three characters wider, let us adjust the

Subject: block/backup: fix memory leak in bdrv_backup_top_append()
Git-commit: fb574de81bfdd71fdb0315105a3a7761efb68395
bdrv_open_driver() allocates bs->opaque according to drv->instance_size.
There is no need to allocate it and overwrite opaque in
bdrv_backup_top_append().

Subject: block/backup-top: fix failure path
Git-commit 0df62f45c1de6c020f1e6fba4eeafd248209b003
We can't access top after call bdrv_backup_top_drop, as it is already
freed at this time.
Also, no needs to unref target child by hand, it will be unrefed on
bdrv_close() automatically.
So, just do bdrv_backup_top_drop if append succeed and one bdrv_unref
otherwise.
Note, that in !appended case bdrv_unref(top) moved into drained section
on source. It doesn't really matter, but just for code simplicity.

There is a use-after-free possible: bdrv_unref_child() leaves
bs->backing freed but not NULL. bdrv_attach_child may produce nested
polling loop due to drain, than access of freed pointer is possible.
I've produced the following crash on 30 iotest with modified code. It
does not reproduce on master, but still seems possible:

Subject: block/block-copy: fix progress calculation
Git-commit: d0ebeca14a585f352938062ef8ddde47fe4d39f9
Assume we have two regions, A and B, and region B is in-flight now,
region A is not yet touched, but it is unallocated and should be
skipped.
Correspondingly, as progress we have
total = A + B
current = 0
If we reset unallocated region A and call progress_reset_callback,
it will calculate 0 bytes dirty in the bitmap and call
job_progress_set_remaining, which will set
total = current + 0 = 0 + 0 = 0
So, B bytes are actually removed from total accounting. When job
finishes we'll have
total = 0
current = B
, which doesn't sound good.
This is because we didn't considered in-flight bytes, actually when
calculating remaining, we should have set (in_flight + dirty_bytes)
as remaining, not only dirty_bytes.
To fix it, let's refactor progress calculation, moving it to block-copy
itself instead of fixing callback. And, of course, track in_flight
bytes count.
We still have to keep one callback, to maintain backup job bytes_read
calculation, but it will go on soon, when we turn the whole backup
process into one block_copy call.

Subject: block: fix crash on zero-length unaligned write and read
Git-commit: ac9d00bf7b47acae6b0e42910d9ed55fef3af5b8
Commit 7a3f542fbd "block/io: refactor padding" occasionally dropped
aligning for zero-length request: bdrv_init_padding() blindly return
false if bytes == 0, like there is nothing to align.
This leads the following command to crash:
./qemu-io --image-opts -c 'write 1 0' \
driver=blkdebug,align=512,image.driver=null-co,image.size=512
>> qemu-io: block/io.c:1955: bdrv_aligned_pwritev: Assertion
`(offset & (align - 1)) == 0' failed.
>> Aborted (core dumped)
Prior to 7a3f542fbd we does aligning of such zero requests. Instead of
recovering this behavior let's just do nothing on such requests as it
is useless.
Note that driver may have special meaning of zero-length reqeusts, like
qcow2_co_pwritev_compressed_part, so we can't skip any zero-length
operation. But for unaligned ones, we can't pass it to driver anyway.
This commit also fixes crash in iotest 80 running with -nocache:
./check -nocache -qcow2 80
which crashes on same assertion due to trying to read empty extra data
in qcow2_do_read_snapshots().

Git-commit: 4ab78b19189a81038e744728ed949d09aa477550
Prior to 1143ec5ebf4 it was OK to qemu_iovec_from_buf() from aligned-up
buffer to original qiov, as qemu_iovec_from_buf() will stop at qiov end
anyway.
But after 1143ec5ebf4 we assume that bdrv_co_do_copy_on_readv works on
part of original qiov, defined by qiov_offset and bytes. So we must not
touch qiov behind qiov_offset+bytes bound. Fix it.

nbd_client_connect() returns error status. Here is an easy way to
reproduce:
1. run qemu-iotests as follow and check the result with asan:
./check -raw 143

On success path we return what inflate() returns instead of 0. And it
most probably works for Z_STREAM_END as it is positive, but is
definitely broken for Z_BUF_ERROR.
While being here, switch to errno return code, to be closer to
qcow2_compress API (and usual expectations).
Revert condition in if to be more positive. Drop dead initialization of
ret.

Subject: hmat acpi: Build Memory Proximity Domain Attributes Structure(s)
Git-commit: e6f123c3b81241be33f1b763d0ff8b36d1ae9c1e
References: jsc#SLE-8897
HMAT is defined in ACPI 6.3: 5.2.27 Heterogeneous Memory Attribute Table
(HMAT). The specification references below link:
http://www.uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf
It describes the memory attributes, such as memory side cache
attributes and bandwidth and latency details, related to the
Memory Proximity Domain. The software is
expected to use this information as hint for optimization.
This structure describes Memory Proximity Domain Attributes by memory
subsystem and its associativity with processor proximity domain as well as
hint for memory usage.
In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables.

References: jsc#SLE-8897
This structure describes memory side cache information for memory
proximity domains if the memory side cache is present and the
physical device forms the memory side cache.
The software could use this information to effectively place
the data in memory to maximize the performance of the system
memory that use the memory side cache.

definition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 2104df2a1fbf44b2564427aa72fd58d66ce290a7
The Cubieboard is a singleboard computer with an Allwinner A10 System-on-Chip [1].
As documented in the Allwinner A10 User Manual V1.5 [2], the SoC has an ARM
Cortex-A8 processor. Currently the Cubieboard machine definition specifies the
ARM Cortex-A9 in its description and as the default CPU.
This patch corrects the Cubieboard machine definition to use the ARM Cortex-A8.
The only user-visible effect is that our textual description of the
machine was wrong, because hw/arm/allwinner-a10.c always creates a
Cortex-A8 CPU regardless of the default value in the MachineClass struct.

Per the specification, and as observed in hardware, the SMMUv3 aligns
the SMMU_STRTAB_BASE address to the size of the table by masking out the
respective least significant bits in the ADDR field.
Apply this masking logic to our smmu_find_ste() lookup function per the
specification.

Subject: hw/arm/smmuv3: Apply address mask to linear strtab base address
Git-commit: 3d44c60500785f18bb469c9de0aeba7415c0f28f
In the SMMU_STRTAB_BASE register, the stream table base address only
occupies bits [51:6]. Other bits, such as RA (bit [62]), must be masked
out to obtain the base address.
The branch for 2-level stream tables correctly applies this mask by way
of SMMU_BASE_ADDR_MASK, but the one for linear stream tables does not.
Apply the missing mask in that case as well so that the correct stream
base address is used by guests which configure a linear stream table.
Linux guests are unaffected by this change because they choose a 2-level
stream table layout for the QEMU SMMUv3, based on the size of its stream
ID space.

Subject: hw/arm/smmuv3: Check stream IDs against actual table LOG2SIZE
Git-commit: 05ff2fb80ce4ca85d8a39d48ff8156de739b4f51
When checking whether a stream ID is in range of the stream table, we
have so far been only checking it against our implementation limit
(SMMU_IDR1_SIDSIZE). However, the guest can program the
STRTAB_BASE_CFG.LOG2SIZE field to a size that is smaller than this
limit.
Check the stream ID against this limit as well to match the hardware
behavior of raising C_BAD_STREAMID events in case the limit is exceeded.
Also, ensure that we do not go one entry beyond the end of the table by
checking that its index is strictly smaller than the table size.

Subject: hw/arm/smmuv3: Correct SMMU_BASE_ADDR_MASK value
Git-commit: 3293b9f514a413e019b7dbc9d543458075b4849e
There are two issues with the current value of SMMU_BASE_ADDR_MASK:
- At the lower end, we are clearing bits [4:0]. Per the SMMUv3 spec,
we should also be treating bit 5 as zero in the base address.
- At the upper end, we are clearing bits [63:48]. Per the SMMUv3 spec,
only bits [63:52] must be explicitly treated as zero.
Update the SMMU_BASE_ADDR_MASK value to mask out bits [63:52] and [5:0].

Subject: hw/arm/smmuv3: Report F_STE_FETCH fault address in correct word
position
Git-commit: b255cafb59578d16716186ed955717bc8f87bdb7
The smmuv3_record_event() function that generates the F_STE_FETCH error
uses the EVT_SET_ADDR macro to record the fetch address, placing it in
32-bit words 4 and 5.
The correct position for this address is in words 6 and 7, per the
SMMUv3 Architecture Specification.
Update the function to use the EVT_SET_ADDR2 macro instead, which is the
macro intended for writing to these words.

Subject: hw/arm/smmuv3: Use correct bit positions in EVT_SET_ADDR2 macro
Git-commit: a7f65ceb851af5a5b639c6e30801076d848db2c2
The bit offsets in the EVT_SET_ADDR2 macro do not match those specified
in the ARM SMMUv3 Architecture Specification. In all events that use
this macro, e.g. F_WALK_EABT, the faulting fetch address or IPA actually
occupies the 32-bit words 6 and 7 in the event record contiguously, with
the upper and lower unused bits clear due to alignment or maximum
supported address bits. How many bits are clear depends on the
individual event type.
Update the macro to write to the correct words in the event record so
that guest drivers can obtain accurate address information on events.

Subject: hw/i386: disable smbus migration for xenfv
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.
Adjust 'xenfv' to stay compatible with with 'pc-i440fx-3.1':
- the toolstack can not use '-M pc-i440fx-3.1,accel=xen -device xen-platform'
because this would move the PCI device from 00:02.0 to 00:04.0
- disable pvh.
Running PVH may require dedicated device_model_args= options which select
'pc-i440fx-4.x'

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: hw/intc/arm_gicv3_kvm: Stop wrongly programming GICR_PENDBASER.PTZ
bit
Git-commit: 618bacabd3c8c3360be795cd8763bacdf5bec101
If LPIs are disabled, KVM will just ignore the GICR_PENDBASER.PTZ bit when
restoring GICR_CTLR. Setting PTZ here makes littlt sense in "reduce GIC
initialization time".
And what's worse, PTZ is generally programmed by guest to indicate to the
Redistributor whether the LPI Pending table is zero when enabling LPIs.
If migration is triggered when the PTZ has just been cleared by guest (and
before enabling LPIs), we will see PTZ==1 on the destination side, which
is not as expected. Let's just drop this hackish userspace behavior.
Also take this chance to refine the comment a bit.

i386-Resolve-CPU-models-to-v1-by-default.patch

Subject: i386: Resolve CPU models to v1 by default
Git-commit: ad18392892c04637fb56956d997f4bc600224356
When using `query-cpu-definitions` using `-machine none`,
QEMU is resolving all CPU models to their latest versions. The
actual CPU model version being used by another machine type (e.g.
`pc-q35-4.0`) might be different.
In theory, this was OK because the correct CPU model
version is returned when using the correct `-machine` argument.
Except that in practice, this breaks libvirt expectations:
libvirt always use `-machine none` when checking if a CPU model
is runnable, because runnability is not expected to be affected
when the machine type is changed.
For example, when running on a Haswell host without TSX,
Haswell-v4 is runnable, but Haswell-v1 is not. On those hosts,
`query-cpu-definitions` says Haswell is runnable if using
`-machine none`, but Haswell is actually not runnable using any
of the `pc-*` machine types (because they resolve Haswell to
Haswell-v1). In other words, we're breaking the "runnability
guarantee" we promised to not break for a few releases (see
qemu-deprecated.texi).
To address this issue, change the default CPU model version to v1
on all machine types, so we make `query-cpu-definitions` output
when using `-machine none` match the results when using `pc-*`.
This will change in the future (the plan is to always return the
latest CPU model version if using `-machine none`), but only
after giving libvirt the opportunity to adapt.

Some tests create huge (but sparse) files, and to be able to run those
tests in certain limited environments (like CI containers), we have to
check for the possibility to create such files first. Thus let's introduce
a common function to check for large files, and replace the already
existing checks in the iotests 005 and 220 with this function.

Git-commit: efd0e5a1215bbdfd28168485800f5cfec9735cf8
Test 060 fails in the arm64, s390x and ppc64le LXD containers on Travis
(which we will hopefully enable in our CI soon). These containers
apparently do not allow large files to be created. The repair process
in test 060 creates a file of 64 GiB, so test first whether such large
files are possible and skip the test if that's not the case.

+""" Test description
+
+When performing a backup, all writes on the source subtree must go through the
+backup-top filter so it can copy all data to the target before it is changed.
+backup-top filter is appended above source node, to achieve this thing, so all
+parents of source node are handled. A configuration with side parents of source
+sub-tree with write permission is unsupported (we'd have append several
+backup-top filter like nodes to handle such parents). The test create an
+example of such configuration and checks that a backup is then not allowed
+(blockdev-backup command should fail).
+
+The configuration:
+
+ ┌────────┐ target ┌─────────────┐
+ │ target │ ◀─────── │ backup_top │
+ └────────┘ └─────────────┘
+ │
+ │ backing
+ ▼
+ ┌─────────────┐
+ │ source │
+ └─────────────┘
+ │
+ │ file
+ ▼
+ ┌─────────────┐ write perm ┌───────┐
+ │ base │ ◀──────────── │ other │
+ └─────────────┘ └───────┘
+
+On activation (see .active field of backup-top state in block/backup-top.c),
+backup-top is going to unshare write permission on its source child. Write
+unsharing will be propagated to the "source->base" link and will conflict with
+other node write permission. So permission update will fail and backup job will
+not be started.
+
+Note, that the only thing which prevents backup of running on such
+configuration is default permission propagation scheme. It may be altered by
+different block drivers, so backup will run in invalid configuration. But
+something is better than nothing. Also, before the previous commit (commit
+preceding this test creation), starting backup on such configuration led to
+crash, so current "something" is a lot better, and this test actual goal is
+to check that crash is fixed :)

Subject: iscsi: Cap block count from GET LBA STATUS (CVE-2020-1711)
Git-commit: 693fd2acdf14dd86c0bf852610f1c2cca80a74dc
References: bsc#1166240, CVE-2020-1711
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.
Fixes: CVE-2020-1711

Git-commit: 322f244aaa80a5208090d41481c1c09c6face66b
A regression that was introduced, with the refactor to TranslatorOps,
drops two lines that update the PC when single-stepping is being performed.

Subject: migration: Rate limit inside host pages
Git-commit: 97e1e06780e70f6e98a0d2df881e0c0927d3aeb6
When using hugepages, rate limiting is necessary within each huge
page, since a 1G huge page can take a significant time to send, so
you end up with bursty behaviour.
Fixes: 4c011c37ecb3 ("postcopy: Send whole huge pages")

Git-commit: 27d07fcfa70c3afa0664288cbce5334ed9595a3a
local_err is used again in secondary_vm_do_failover() after
replication_stop_all(), so we must zero it. Otherwise try to set
non-NULL local_err will crash.

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")

Git-commit: 8ffb7265af64ec81748335ec8f20e7ab542c3850
References: bsc#1168713, CVE-2020-11102
Tulip network driver while copying tx/rx buffers does not check
frame size against r/w data length. This may lead to OOB buffer
access. Add check to avoid it.
Limit iterations over descriptors to avoid potential infinite
loop issue in tulip_xmit_list_update.

Subject: numa: Extend CLI to provide initiator information for numa nodes
Git-commit: 244b3f4485a07c7ce4b7123d6ce9d8c6012756e8
References: jsc#SLE-8897
In ACPI 6.3 chapter 5.2.27 Heterogeneous Memory Attribute Table (HMAT),
The initiator represents processor which access to memory. And in 5.2.27.3
Memory Proximity Domain Attributes Structure, the attached initiator is
defined as where the memory controller responsible for a memory proximity
domain. With attached initiator information, the topology of heterogeneous
memory can be described. Add new machine property 'hmat' to enable all
HMAT specific options.
Extend CLI of "-numa node" option to indicate the initiator numa node-id.
In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables. Before using initiator option, enable HMAT with
-machine hmat=on.

Subject: numa: Extend CLI to provide memory latency and bandwidth information
Git-commit: 9b12dfa03a94d7f7a4b54eb67229a31e58193384
References: jsc#SLE-8897
Add -numa hmat-lb option to provide System Locality Latency and
Bandwidth Information. These memory attributes help to build
System Locality Latency and Bandwidth Information Structure(s)
in ACPI Heterogeneous Memory Attribute Table (HMAT). Before using
hmat-lb option, enable HMAT with -machine hmat=on.

Git-commit: c412a48d4d91e8f8b89aae02de0f44f1f0b729e5
References: jsc#SLE-8897
Add -numa hmat-cache option to provide Memory Side Cache Information.
These memory attributes help to build Memory Side Cache Information
Structure(s) in ACPI Heterogeneous Memory Attribute Table (HMAT).

Subject: numa: properly check if numa is supported
Git-commit: fcd3f2cc124600385dba46c69a80626985c15b50
Commit aa57020774b, by mistake used MachineClass::numa_mem_supported
to check if NUMA is supported by machine and also as unrelated change
set it to true for sbsa-ref board.
Luckily change didn't break machines that support NUMA, as the field
is set to true for them.
But the field is not intended for checking if NUMA is supported and
will be flipped to false within this release for new machine types.
Fix it:
- by using previously used condition
!mc->cpu_index_to_instance_props || !mc->get_default_cpu_node_id
the first time and then use MachineState::numa_state down the road
to check if NUMA is supported
- dropping stray sbsa-ref chunk

From: Janosch Frank <frankja@linux.ibm.com>

Subject: pc-bios: s390x: Save iplb location in lowcore
Git-commit: 9bfc04f9ef6802fff0fc77130ff345a541783363
References: bsc#1163140, bsc#1167075
The POP states that for a list directed IPL the IPLB is stored into
memory by the machine loader and its address is stored at offset 0x14
of the lowcore.
ZIPL currently uses the address in offset 0x14 to access the IPLB and
acquire flags about secure boot. If the IPLB address points into
memory which has an unsupported mix of flags set, ZIPL will panic
instead of booting the OS.
As the lowcore can have quite a high entropy for a guest that did drop
out of protected mode (i.e. rebooted) we encountered the ZIPL panic
quite often.

This code is inside the "if (dinfo)" condition, so testing
again here whether it is NULL is unnecessary.
Fixes: dd59bcae7 (Don't size flash memory to match backing image)

Subject: qcow2: List autoclear bit names in header
Git-commit bb40ebce2cb0bd4bf37968074d43d5a864fb6dee
The feature table is supposed to advertise the name of all feature
bits that we support; however, we forgot to update the table for
autoclear bits. While at it, move the table to read-only memory in
code, and tweak the qcow2 spec to name the second autoclear bit.
Update iotests that are affected by the longer header length.

Subject: qcow2-bitmaps: fix qcow2_can_store_new_dirty_bitmap
Git-commit: a1db8733d28d615bc0daeada6c406a6dd5c5d5ef
qcow2_can_store_new_dirty_bitmap works wrong, as it considers only
bitmaps already stored in the qcow2 image and ignores persistent
BdrvDirtyBitmap objects.
So, let's instead count persistent BdrvDirtyBitmaps. We load all qcow2
bitmaps on open, so there should not be any bitmap in the image for
which we don't have BdrvDirtyBitmaps version. If it is - it's a kind of
corruption, and no reason to check for corruptions here (open() and
close() are better places for it).
