Subject: ui/clipboard: Don't use g_autoptr just to free a variable
Clang doesn't recognize that the variable is being "used" and will emit
a warning:
../ui/clipboard.c:47:34: error: variable 'old' set but not used [-Werror,-Wunused-but-set-variable]
g_autoptr(QemuClipboardInfo) old = NULL;
^
1 error generated.
OK, fine. Just do things the old way.

This is temporary commit from upstream submission necessary for build to pass.
We expect proper fix included upstream later.

Subject: Initial redhat build
This patch introduces redhat build structure in redhat subdirectory. In addition,
several issues are fixed in QEMU tree:
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
- As we use qemu-kvm as name in all places, this is updated to be consistent
- Man page renamed from qemu to qemu-kvm
- man page is installed using make install so we have to fix it in qemu tree
We disable make check due to issues with some of the tests.
This rebase is based on qemu-kvm-6.1.0-8.el9

+QEMU tracing using systemtap-initscript
+---------------------------------------
+
+You can capture QEMU trace data all the time using systemtap-initscript. This
+uses SystemTap's flight recorder mode to trace all running guests to a
+fixed-size buffer on the host. Old trace entries are overwritten by new
+entries when the buffer size wraps.
+
+1. Install the systemtap-initscript package:
+ # yum install systemtap-initscript
+
+2. Install the systemtap scripts and the conf file:
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
+
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
+script can be customized to add or remove trace events provided in
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
+
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
+recorder buffer size and whether to store traces in memory only or disk too.
+See stap(1) for option documentation.
+
+3. Start the systemtap service.
+　# service systemtap start qemu_kvm
+
+4. Make the service start at boot time.
+　# chkconfig systemtap on
+
+5. Confirm that the service works.
+ # service systemtap status qemu_kvm
+ qemu_kvm is running...
+
+When you want to inspect the trace buffer, perform the following steps:
+
+1. Dump the trace buffer.
+ # staprun -A qemu_kvm >/tmp/trace.log
+
+2. Start the systemtap service because the preceding step stops the service.
+ # service systemtap start qemu_kvm
+
+3. Translate the trace record to readable format.
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

Go through all groups to get count of total number of devices
active to enforce limit
Reasoning from Alex for the limit(32) - Assuming 3 slots per
device, with 125 slots (number of memory slots for RHEL 7),
we can support almost 40 devices and still have few slots left
for other uses. Stepping down a bit, the number 32 arbitrarily
matches the number of slots on a PCI bus and is also a nice power
of two.
Count of slots increased to 509 later so we could increase limit
to 64 as some usecases require more than 32 devices.

Subject: globally limit the maximum number of CPUs
We now globally limit the number of VCPUs.
Especially, there is no way one can specify more than
max_cpus VCPUs for a VM.
This allows us the restore the ppc max_cpus limitation to the upstream
default and minimize the ppc hack in kvm-all.c.

We need a fix for RHEL 7.4 and 7.3.z, but unfortunately upstream isn't
ready. If it were, the changes will be too invasive. To have an idea:
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05400.html
is an incomplete attempt to fix part of the issue, and the remaining
work unfortunately involve even more complex changes.
As a band-aid, this partially reverts the effect of ef8875b
(virtio-scsi: Remove op blocker for dataplane, since v2.7). We cannot
simply revert that commit as a whole because we already shipped it in
qemu-kvm-rhev 7.3, since when, block jobs has been possible. We should
only block what has been broken. Also, faithfully reverting the above
commit means adding back the removed op blocker, but that is not enough,
because it still crashes when inserting media into an initially empty
scsi-cd.
All in all, scsi-cd on virtio-scsi-dataplane has basically been unusable
unless the scsi-cd never enters an empty state, so, disable it
altogether. Otherwise it would be much more difficult to avoid
crashing.

Most current POWER guests require 64kiB page support, so that's the default
for the cap-hpt-max-pagesize option in qemu which limits available guest
page sizes. We warn if the value is set smaller than that, but don't
outright fail upstream, because we need to allow for the possibility of
guest (and/or host) kernels configured for 4kiB page sizes.
Downstream, however, we simply don't support 4kiB pagesize configured
kernels in guest or host, so we can have qemu simply error out in this
situation.
Testing: Attempted to start a guest with cap-hpt-max-page-size=4k and verified
it failed immediately with a qemu error

qcow2 v3 has been around for a long time (since QEMU 1.1/RHEL 7), so
there is no real reason any more to use it. People still using it might
do so unintentionally. Warn about it and suggest upgrading during the
RHEL 9 timeframe so that the code can possibly be disabled in RHEL 10.
The warning is restricted to read-write mode and the system emulator.
The primary motivation for not having it in qemu-img is that 'qemu-img
amend' for upgrades would warn otherwise. It also avoids having to make
too many changes to the test suite.
bdrv_uses_whitelist() is used as a proxy for deciding whether we are
running in a tool or the system emulator. This is not entirely clean,
but it's what is available and the same function qcow2_do_open() already
uses it this way for another warning.

hw_compat_rhel_8_4 has an issue: it affects only "virtio-net-pci"
but not "virtio-net-pci-transitional" and
"virtio-net-pci-non-transitional". The solution is to use the
"virtio-net-pci-base" type in compat_props.
An equivalent fix will be submitted for hw_compat_5_2 upstream.

Add pc_rhel_8_5_compat as the merge of pc_compat_6_1 and pc_compat_6_0
(since 8.5 was based on 6.0).
Note, x-keep-pci-slot-hpc flipped back and forward, leaving it out
looks like it leaves us with the original.

The tests/ directory within the tests-src/ directory is setup to remain a copy
of a subset of the tests/ directory from the QEMU source tree
The avocado_qemu tests and qemu-iotests, along with files required for the
execution of the avocado_qemu tests (scripts/qemu.py and scripts/qmp/) will be
installed in a new location - /usr/lib64/qemu-kvm/tests-src/
avocado_qemu tests:
The avocado_qemu tests can be executed by running the following avocado command:
avocado run -p qemu_bin=/usr/libexec/qemu-kvm /usr/lib64/qemu-kvm/tests/acceptance/
Avocado needs to be installed separately using either pip or from source as
Avocado is not being packaged for RHEL-8.
qemu-iotests:
symlinks to corresponding binaries need to be created for QEMU_PROG,
QEMU_IO_PROG, QEMU_IMG_PROG, and QEMU_NBD_PROG before the iotests can be
executed.
The primary purpose of this package is to make these tests available to be
executed as gating tests for the virt module in the RHEL-8 OSCI environment.

We want to make it obvious that we consider machine types for older
RHEL major releases to be deprecated; we only carry them for
compatibility purposes.
Let's mark all rhel-7.x and rhel-8.x machine type as deprecated via
QEMU's existing deprecation mechanism; those machine types will
continue to work as expected, but commands like 'virsh capabilities',
'virsh dominfo', or the libvirt log will tag the machine as
deprecated.

Commit [2] broke original '\0' padding of OEM ID and OEM Table ID
fields in headers of ACPI tables. While it doesn't have impact on
default values since QEMU uses 6 and 8 characters long values
respectively, it broke usecase where IDs are provided on QEMU CLI.
It shouldn't affect guest (but may cause licensing verification
issues in guest OS).
One of the broken usecases is user supplied SLIC table with IDs
shorter than max possible length, where [2] mangles IDs with extra
spaces in RSDT and FADT tables whereas guest OS expects those to
mirror the respective values of the used SLIC table.
Fix it by replacing whitespace padding with '\0' padding in
accordance with [1] and expectations of guest OS
1) ACPI spec, v2.0b
17.2 AML Grammar Definition
...
//OEM ID of up to 6 characters. If the OEM ID is
//shorter than 6 characters, it can be terminated
//with a NULL character.

if QEMU is started with used provided SLIC table blob,
-acpitable sig=SLIC,oem_id='CRASH ',oem_table_id="ME",oem_rev=00002210,asl_compiler_id="",asl_compiler_rev=00000000,data=/dev/null
it will assert with:
hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)
and following backtrace:
...
build_append_padded_str (array=0x555556afe320, str=0x555556afdb2e "CRASH ME", maxlen=0x6, pad=0x20) at hw/acpi/aml-build.c:61
acpi_table_begin (desc=0x7fffffffd1b0, array=0x555556afe320) at hw/acpi/aml-build.c:1727
build_fadt (tbl=0x555556afe320, linker=0x555557ca3830, f=0x7fffffffd318, oem_id=0x555556afdb2e "CRASH ME", oem_table_id=0x555556afdb34 "ME") at hw/acpi/aml-build.c:2064
...
which happens due to acpi_table_begin() expecting NULL terminated
oem_id and oem_table_id strings, which is normally the case, but
in case of user provided SLIC table, oem_id points to table's blob
directly and as result oem_id became longer than expected.
Fix issue by handling oem_id consistently and make acpi_get_slic_oem()
return NULL terminated strings.
PS:
After [1] refactoring, oem_id semantics became inconsistent, where
NULL terminated string was coming from machine and old way pointer
into byte array coming from -acpitable option. That used to work
since build_header() wasn't expecting NULL terminated string and
blindly copied the 1st 6 bytes only.
However commit [2] broke that by replacing build_header() with
acpi_table_begin(), which was expecting NULL terminated string
and was checking oem_id size.

on creation a PCIDevice has power turned on at the end of pci_qdev_realize()
however later on if PCIe slot isn't populated with any children
it's power is turned off. It's fine if native hotplug is used
as plug callback will power slot on among other things.
However when ACPI hotplug is enabled it replaces native PCIe plug
callbacks with ACPI specific ones (acpi_pcihp_device_*plug_cb) and
as result slot stays powered off. It works fine as ACPI hotplug
on guest side takes care of enumerating/initializing hotplugged
device. But when later guest is migrated, call chain introduced by]
commit d5daff7d312 (pcie: implement slot power control for pcie root ports)
pcie_cap_slot_post_load()
-> pcie_cap_update_power()
-> pcie_set_power_device()
-> pci_set_power()
-> pci_update_mappings()
will disable earlier initialized BARs for the hotplugged device
in powered off slot due to commit 23786d13441 (pci: implement power state)
which disables BARs if power is off.
Fix it by setting PCI_EXP_SLTCTL_PCC to PCI_EXP_SLTCTL_PWR_ON
on slot (root port/downstream port) at the time a device
hotplugged into it. As result PCI_EXP_SLTCTL_PWR_ON is migrated
to target and above call chain keeps device plugged into it
powered on.

bdrv_subtree_drained_end() requires the caller to hold the AioContext
lock for the drained node. Not doing this for nodes outside of the main
AioContext leads to crashes when AIO_WAIT_WHILE() needs to wait and
tries to temporarily release the lock.

RH-Author: Hanna Reitz <hreitz@redhat.com>
RH-MergeRequest: 71: block-backend: prevent dangling BDS pointers across aio_poll()
RH-Commit: [1/2] 1b4cab39bf8c933ab910293a29bfceaa9e821068 (hreitz/qemu-kvm-c-9-s)

The BlockBackend root child can change when aio_poll() is invoked. This
happens when a temporary filter node is removed upon blockjob
completion, for example.
Functions in block/block-backend.c must be aware of this when using a
blk_bs() pointer across aio_poll() because the BlockDriverState refcnt
may reach 0, resulting in a stale pointer.
One example is scsi_device_purge_requests(), which calls blk_drain() to
wait for in-flight requests to cancel. If the backup blockjob is active,
then the BlockBackend root child is a temporary filter BDS owned by the
blockjob. The blockjob can complete during bdrv_drained_begin() and the
last reference to the BDS is released when the temporary filter node is
removed. This results in a use-after-free when blk_drain() calls
bdrv_drained_end(bs) on the dangling pointer.
Explicitly hold a reference to bs across block APIs that invoke
aio_poll().

We update the block-status cache whenever we get new information from a
bdrv_co_block_status() call to the block driver. However, if we have
passed want_zero=false to that call, it may flag areas containing zeroes
as data, and so we would update the block-status cache with wrong
information.
Therefore, we should not update the cache with want_zero=false.

Our two timers must not remain armed beyond nbd_clear_bdrvstate(), or
they will access freed data when they fire.
This patch is separate from the patches that actually fix the issue
(HEAD^^ and HEAD^) so that you can run the associated regression iotest
(281) on a configuration that reproducibly exposes the bug.

We start the reconnect delay timer to cancel the reconnection attempt
after a while. Once nbd_co_do_establish_connection() has returned, this
attempt is over, and we no longer need the timer.
Delete it before returning from nbd_reconnect_attempt(), so that it does
not persist beyond the I/O request that was paused for reconnecting; we
do not want it to fire in a drained section, because all sort of things
can happen in such a section (e.g. the AioContext might be changed, and
we do not want the timer to fire in the wrong context; or the BDS might
even be deleted, and so the timer CB would access already-freed data).

RH-MergeRequest: 58: block/nvme: fix infinite loop in nvme_free_req_queue_cb()
RH-Commit: [1/1] 544b3f310d791a20c63b51947de0c6cbb60b0d5b (stefanha/centos-stream-qemu-kvm)

When the request free list is exhausted the coroutine waits on
q->free_req_queue for the next free request. Whenever a request is
completed a BH is scheduled to invoke nvme_free_req_queue_cb() and wake
up waiting coroutines.
1. nvme_get_free_req() waits for a free request:
while (q->free_req_head == -1) {
...
trace_nvme_free_req_queue_wait(q->s, q->index);
qemu_co_queue_wait(&q->free_req_queue, &q->lock);
...
}
2. nvme_free_req_queue_cb() wakes up the coroutine:
while (qemu_co_enter_next(&q->free_req_queue, &q->lock)) {
^--- infinite loop when free_req_head == -1
}
nvme_free_req_queue_cb() and the coroutine form an infinite loop when
q->free_req_head == -1. Fix this by checking q->free_req_head in
nvme_free_req_queue_cb(). If the free request list is exhausted, don't
wake waiting coroutines. Eventually an in-flight request will complete
and the BH will be scheduled again, guaranteeing forward progress.

the assumption that we can't hit a hole if we do not diff against a snapshot was wrong.
We can see a hole in an image if we diff against base if there exists an older snapshot
of the image and we have discarded blocks in the image where the snapshot has data.
Fix this by simply handling a hole like an unallocated area. There are no callbacks
for unallocated areas so just bail out if we hit a hole.

librbd had a bug until early 2022 that affected all versions of ceph that
supported fast-diff. This bug results in reporting of incorrect offsets
if the offset parameter to rbd_diff_iterate2 is not object aligned.
This patch works around this bug for pre Quincy versions of librbd.

Truly allow TCG ITS instantiation according to the no_tcg_its
class flag. Otherwise it is always set to false.
We also take benefit of this patch to do some minor non

Upstream: no
Register the "iommu" option as a class property. This mirrors what
was done in upstream commit b91def7b ("arm/virt: Register
most properties as class properties").
While we are at it we also move the "x-oem-id" and "x-oem-table-id"
registrations at the very end of the rhel_machine_class_init()
function. This makes our life easier when comparing with upstream.

If call virtio_queue_set_host_notifier_mr fails, should free
host-notifier memory-region.
This problem can trigger a coredump with some vDPA drivers (mlx5,
but not with the vdpasim), if we unplug the virtio-net card from
the guest after a stop/start.
The same fix has been done for vhost-user:

i386: Add Icelake-Server-v6 CPU model with 5-level EPT support
Windows 11 with WSL2 enabled (Hyper-V) fails to boot with Icelake-Server
{-v5} CPU model but boots well with '-cpu host'. Apparently, it expects
5-level paging and 5-level EPT support to come in pair but QEMU's
Icelake-Server CPU model lacks the later. Introduce 'Icelake-Server-v6'
CPU model with 'vmx-page-walk-5' enabled by default.

Put an NBD block device into an I/O thread, and then read data from it,
hoping that the NBD connection will yield during that read. When it
does, the coroutine must be reentered in the block device's I/O thread,
which will only happen if the NBD block driver attaches the connection's
QIOChannel to the new AioContext. It did not do that after 4ddb5d2fde
("block/nbd: drop connection_co") and prior to "block/nbd: Move s->ioc
on AioContext change", which would cause an assertion failure.
To improve our chances of yielding, the NBD server is throttled to
reading 64 kB/s, and the NBD client reads 128 kB, so it should yield at
some point.

Prior to "block/nbd: Delete reconnect delay timer when done" and
"block/nbd: Delete open timer when done", both of those timers would
remain scheduled even after successfully (re-)connecting to the server,
and they would not even be deleted when the BDS is deleted.
This test constructs exactly this situation:
(1) Configure an @open-timeout, so the open timer is armed, and
(2) Configure a @reconnect-delay and trigger a reconnect situation
(which succeeds immediately), so the reconnect delay timer is armed.
Then we immediately delete the BDS, and sleep for longer than the
@open-timeout and @reconnect-delay. Prior to said patches, this caused
one (or both) of the timer CBs to access already-freed data.
Accessing freed data may or may not crash, so this test can produce
false successes, but I do not know how to show the problem in a better
or more reliable way. If you run this test on "block/nbd: Assert there
are no timers when closed" and without the fix patches mentioned above,
you should reliably see an assertion failure.
(But all other tests that use the reconnect delay timer (264 and 277)
will fail in that configuration, too; as will nbd-reconnect-on-open,
which uses the open timer.)
Remove this test from the quick group because of the two second sleep
this patch introduces.
(I decided to put this test case into 281, because the main bug this
series addresses is in the interaction of the NBD block driver and I/O
threads, which is precisely the scope of 281. The test case for that
other bug will also be put into the test class added here.
Also, excuse the test class's name, I couldn't come up with anything
better. The "yield" part will make sense two patches from now.)

Conflict:
- @open-timeout was introduced after the 6.2 release, and has not been
backported. Consequently, there is no open_timer, and we can (and
must) drop the respective parts of the test here.

Subject: [PATCH 2/8] iotests: Test blockdev-reopen with iothreads and
throttling
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 73: block: Lock AioContext for drain_end in blockdev-reopen
RH-Commit: [2/2] d19d5fa9efa4813ece75708436891041754ab910 (kmwolf/centos-qemu-kvm)

RH-Acked-by: Hanna Reitz <hreitz@redhat.com>
The 'throttle' block driver implements .bdrv_co_drain_end, so
blockdev-reopen will have to wait for it to complete in the polling
loop at the end of qmp_blockdev_reopen(). This makes AIO_WAIT_WHILE()
release the AioContext lock, which causes a crash if the lock hasn't
correctly been taken.

This demonstrates what happens when the block status changes in
sub-min_sparse granularity, but all of the parts are zeroed out. The
alignment logic in is_allocated_sectors() prevents that the target image
remains fully sparse as expected, but turns it into a data cluster of
explicit zeros.

Add a new test to verify that want_zero=false block-status calls do not
pollute the block-status cache for want_zero=true calls.
We check want_zero=true calls and their results using `qemu-img map`
(over NBD), and want_zero=false calls also using `qemu-img map` over
NBD, but using the qemu:allocation-depth context.
(This test case cannot be integrated into nbd-qemu-allocation, because
that is a qcow2 test, and this is a raw test.)

Subject: [PATCH 11/12] iotests/stream-error-on-reset: New test
RH-Author: Hanna Reitz <hreitz@redhat.com>
RH-MergeRequest: 71: block-backend: prevent dangling BDS pointers across aio_poll()
RH-Commit: [2/2] 3167f31b91eb433f338564201f4ef336e39f7f7d (hreitz/qemu-kvm-c-9-s)
RH-Bugzilla: 2040123

RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
Test the following scenario:
- Simple stream block in two-layer backing chain (base and top)
- The job is drained via blk_drain(), then an error occurs while the job
settles the ongoing request
- And so the job completes while in blk_drain()
This was reported as a segfault, but is fixed by "block-backend: prevent
dangling BDS pointers across aio_poll()".

This is a rather simple class that allows creating a QSD instance
running in the background and stopping it when no longer needed.
The __del__ handler is a safety net for when something goes so wrong in
a test that e.g. the tearDown() method is not called (e.g. setUp()
launches the QSD, but then launching a VM fails). We do not want the
QSD to continue running after the test has failed, so __del__() will
take care to kill it.

We should only call the log_global_start/stop when the global dirty track
bitmask changes from zero<->non-zero.
No real issue reported for this yet probably because no immediate user to
enable both dirty rate measurement and migration at the same time. However
it'll be good to be prepared for it.

Subject: [PATCH 6/6] memory: Fix qemu crash on starting dirty log twice with
stopped VM
RH-Author: Peter Xu <peterx@redhat.com>
RH-MergeRequest: 77: memory: Fix qemu crash on continuous migrations of stopped VM
RH-Commit: [2/2] 98ed2ef6226ec80a1896ebb554015aded0dc0c18 (peterx/qemu-kvm)
RH-Bugzilla: 2044818
RH-Acked-by: Paolo Bonzini <None>

QEMU can now easily crash with two continuous migration carried out:
(qemu) migrate -d exec:cat>out
(qemu) migrate_cancel
(qemu) migrate -d exec:cat>out
[crash] ../softmmu/memory.c:2782: memory_global_dirty_log_start: Assertion
`!(global_dirty_tracking & flags)' failed.
It's because memory API provides a way to postpone dirty log stop if the VM is
stopped, and that'll be re-done until the next VM start. It was added in 2017
with commit 1931076077 ("migration: optimize the downtime", 2017-08-01).
However the recent work on allowing dirty tracking to be bitmask broke it,
which is commit 63b41db4bc ("memory: make global_dirty_tracking a bitmask",
2021-11-01).
The fix proposed in this patch contains two things:
(1) Instead of passing over the flags to postpone stop dirty track, we add a
global variable (along with current vmstate_change variable) to record
what flags to stop dirty tracking.
(2) When start dirty tracking, instead if remove the vmstate hook directly,
we also execute the postponed stop process so that we make sure all the
starts and stops will be paired.
This procedure is overlooked in the bitmask-ify work in 2021.

Subject: [PATCH 01/12] numa: Enable numa for SGX EPC sections
RH-Author: Paul Lai <plai@redhat.com>
RH-MergeRequest: 65: Enable SGX and add SGX Numa support
RH-Commit: [1/5] ff69d138c3f5903096388ec7ccf8dc5e6c6c6ffb
RH-Bugzilla: 2033708
RH-Acked-by: Paolo Bonzini <None>

The basic SGX did not enable numa for SGX EPC sections, which
result in all EPC sections located in numa node 0. This patch
enable SGX numa function in the guest and the EPC section can
work with RAM as one numa node.
The Guest kernel related log:
[ 0.009981] ACPI: SRAT: Node 0 PXM 0 [mem 0x180000000-0x183ffffff]
[ 0.009982] ACPI: SRAT: Node 1 PXM 1 [mem 0x184000000-0x185bfffff]
The SRAT table can normally show SGX EPC sections menory info in different
numa nodes.
The SGX EPC numa related command:
......
-m 4G,maxmem=20G \
-smp sockets=2,cores=2 \
-cpu host,+sgx-provisionkey \
-object memory-backend-ram,size=2G,host-nodes=0,policy=bind,id=node0 \
-object memory-backend-epc,id=mem0,size=64M,prealloc=on,host-nodes=0,policy=bind \
-numa node,nodeid=0,cpus=0-1,memdev=node0 \
-object memory-backend-ram,size=2G,host-nodes=1,policy=bind,id=node1 \

Subject: [PATCH 02/12] numa: Support SGX numa in the monitor and Libvirt

RH-Author: Paul Lai <plai@redhat.com>
RH-MergeRequest: 65: Enable SGX and add SGX Numa support
RH-Commit: [2/5] 8c19cfb1a139fd4dbac771e695a133f16a68437f

Add the SGXEPCSection list into SGXInfo to show the multiple
SGX EPC sections detailed info, not the total size like before.
This patch can enable numa support for 'info sgx' command and
QMP interfaces. The new interfaces show each EPC section info
in one numa node. Libvirt can use QMP interface to get the
detailed host SGX EPC capabilities to decide how to allocate
host EPC sections to guest.

RH-MergeRequest: 65: Enable SGX and add SGX Numa support
RH-Commit: [5/5] 0d3b9f37cd3cce202050ba3bd51eef4410ef3d38
RH-Bugzilla: 2033708
RH-Acked-by: Paolo Bonzini <None>

The SGX NUMA patches were merged into Qemu 7.0 release, we need
clarify detailed version history information and also change
some related comments, which make SGX related comments clearer.
The QMP command schema promises backwards compatibility as standard.
We temporarily restore "@section-size", which can avoid incompatible
API breakage. The "@section-size" will be deprecated in 7.2 version.

Consider the case when the whole buffer is zero and end is unaligned.
If i <= tail, we return 1 and do one unaligned WRITE, RMW happens.
If i > tail, we do on aligned WRITE_ZERO (or skip if target is zeroed)
and again one unaligned WRITE, RMW happens.
Let's do better: don't fragment the whole-zero buffer and report it as
ZERO: in case of zeroed target we just do nothing and avoid RMW. If
target is not zeroes, one unaligned WRITE_ZERO should not be much worse
than one unaligned WRITE.

When I fixed up the machine types for 8.5 I missed the
prefer_sockets = true
add them in; it looks like Power, ARM already have them, and I see them
in thuth's s390 patch.

RH-MergeRequest: 62: Fix hot unplug of devices created with -device JSON syntax
RH-Commit: [1/1] 980e505ba215b5f9324c107481c5bb257ae03f42 (kmwolf/centos-qemu-kvm)
RH-Bugzilla: 2036669
RH-Acked-by: Daniel P. Berrangé <berrange@redhat.com>
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
RH-Acked-by: Jano Tomko <None>
The -device JSON syntax impl leaks a reference on the created
DeviceState instance. As a result when you hot-unplug the
device, the device_finalize method won't be called and thus
it will fail to emit the required DEVICE_DELETED event.
A 'json-cli' feature was previously added against the
'device_add' QMP command QAPI schema to indicated to mgmt
apps that -device supported JSON syntax. Given the hotplug
bug that feature flag is not usable for its purpose, so
we add a new 'json-cli-hotplug' feature to indicate the
-device supports JSON without breaking hotplug.

When user uses '-acpitable' to add SLIC table, some ACPI
tables (FADT) will change its 'Oem ID'/'Oem Table ID' fields to
match that of SLIC. Test makes sure thati QEMU handles
those fields correctly when SLIC table is added with
'-acpitable' option.

The next commit will revert OEM fields padding with whitespace to
padding with '\0' as it was before [1]. As result test_oem_fields() will
fail due to unexpectedly smaller ID sizes read from QEMU ACPI tables.
Pad OEM_ID/OEM_TABLE_ID manually with spaces so that values the test
puts on QEMU CLI and expected values match.

Subject: [PATCH 13/14] tests: acpi: test short OEM_ID/OEM_TABLE_ID values in
test_oem_fields()
RH-Author: Igor Mammedov <imammedo@redhat.com>
RH-MergeRequest: 130: acpi: fix QEMU crash when started with SLIC table
RH-Commit: [9/10] f1f9991d5d7ef5afb2f98f4fa81aeb3e3cf32d8f
RH-Bugzilla: 2043531

RH-Acked-by: MST <None>
Previous patch [1] added explicit whitespace padding to OEM_ID/OEM_TABLE_ID
values used in test_oem_fields() testcase to avoid false positive and
bisection issues when QEMU is switched to \0' padding. As result
testcase ceased to test values that were shorter than max possible
length values.
Update testcase to make sure that it's testing shorter IDs like it
used to before [2].

The next commit will revert OEM fields whitespace padding to
padding with '\0' as it was before [1]. That will change OEM
Table ID for:
* SSDT.*: where it was padded from 6 characters to 8
* FACP.slic: where it was padded from 2 characters to 8
after reverting whitespace padding, it will be replaced with
'\0' which effectively will shorten OEM table ID to 6 and 2
characters.
Whitelist affected tables before introducing the change.

With latest clang 13.0.0 we get
../ui/clipboard.c:47:34: error: variable 'old' set but not used [-Werror,-Wunused-but-set-variable]
g_autoptr(QemuClipboardInfo) old = NULL;
^
The compiler can't tell that we only declared this variable in
order to get the side effect of free'ing it when out of scope.
This pattern is a little dubious for a use of g_autoptr, so
rewrite the code to avoid it.

From the call trace, we can see it is a deadlock bug.
vnc_disconnect_finish will acquire the output_mutex.
But, the output_mutex will be acquired again in vnc_clipboard_send.
Repeated locking will cause deadlock. So, I move
qemu_clipboard_peer_unregister() behind vnc_unlock_output();

Subject: [PATCH 3/5] virtiofsd: Drop membership of all supplementary groups
(CVE-2022-0358)
RH-Author: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-MergeRequest: 66: c9s: virtiofsd security fix - drop secondary groups
RH-Commit: [1/1] cdf3b0405ea3369933e76761890f16b040641036 (redhat/centos-stream/src/qemu-kvm)
RH-Bugzilla: 2046201
RH-Acked-by: Hanna Reitz <hreitz@redhat.com>
RH-Acked-by: Sergio Lopez <None>
RH-Acked-by: Vivek Goyal <None>
At the start, drop membership of all supplementary groups. This is
not required.
If we have membership of "root" supplementary group and when we switch
uid/gid using setresuid/setsgid, we still retain membership of existing
supplemntary groups. And that can allow some operations which are not
normally allowed.
For example, if root in guest creates a dir as follows.
$ mkdir -m 03777 test_dir
This sets SGID on dir as well as allows unprivileged users to write into
this dir.
And now as unprivileged user open file as follows.
$ su test
$ fd = open("test_dir/priviledge_id", O_RDWR|O_CREAT|O_EXCL, 02755);
This will create SGID set executable in test_dir/.
And that's a problem because now an unpriviliged user can execute it,
get egid=0 and get access to resources owned by "root" group. This is
privilege escalation.

Add a rhel-9.0.0 q35 machine type; it's currently identical to 8.6.0;
but having a separate machine type will make life easier in the future
when the 8.x types go away.
Note: The smbios stream product name has now changed to 'RHEL'
