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)
RH-Bugzilla: 2040123

RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
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-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.

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.

RH-Bugzilla: 2033626
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>

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.

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 \

Subject: [PATCH 02/12] numa: Support SGX numa in the monitor and Libvirt
interfaces
RH-Author: Paul Lai <plai@redhat.com>
RH-MergeRequest: 65: Enable SGX and add SGX Numa support
RH-Commit: [2/5] 8c19cfb1a139fd4dbac771e695a133f16a68437f

RH-Acked-by: Paolo Bonzini <None>

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.
(qemu) info sgx
SGX support: enabled
SGX1 support: enabled
SGX2 support: enabled
FLC support: enabled
NUMA node #0: size=67108864
NUMA node #1: size=29360128
The QMP interface show:

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.

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.

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.

Subject: [PATCH 2/3] x86: Add q35 RHEL 9.0.0 machine type
RH-Author: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-MergeRequest: 61: x86: Add rhel 8.6.0 & 9.0.0 machine types
RH-Commit: [2/2] 743378502459b978efd632271f97ddb824422203 (dagrh/c-9-s-qemu-kvm)
RH-Bugzilla: 1945666
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Acked-by: Stefano Garzarella <sgarzare@redhat.com>
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
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'
