-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The TLS handshake make take some time to complete, during which time an
-I/O watch might be registered with the main loop. If the owner of the
-I/O channel invokes qio_channel_close() while the handshake is waiting
-to continue the I/O watch must be removed. Failing to remove it will
-later trigger the completion callback which the owner is not expecting
-to receive. In the case of the VNC server, this results in a SEGV as
-vnc_disconnect_start() tries to shutdown a client connection that is
-already gone / NULL.

+RH-Commit: [2/3] 1cb3d72b86ced0f70a09dfa0d325ae8a85db1b2b (berrange/centos-src-qemu)
+
+This commit results in unexpected termination of the TLS connection.
+When 'fd_can_read' returns 0, the code goes on to pass a zero length
+buffer to qio_channel_read. The TLS impl calls into gnutls_recv()
+with this zero length buffer, at which point GNUTLS returns an error
+GNUTLS_E_INVALID_REQUEST. This is treated as fatal by QEMU's TLS code
+resulting in the connection being torn down by the chardev.
+
+Simply skipping the qio_channel_read when the buffer length is zero
+is also not satisfactory, as it results in a high CPU burn busy loop
+massively slowing QEMU's functionality.
+
+The proper solution is to avoid tcp_chr_read being called at all
+unless the frontend is able to accept more data. This will be done
+in a followup commit.

+RH-Commit: [3/3] b58e6c19c2b11d5d28db31cf1386226fb01d195e (berrange/centos-src-qemu)
+
+This reverts commit a7077b8e354d90fec26c2921aa2dea85b90dff90,
+and add comments to explain why child sources cannot be used.
+
+When a GSource is added as a child of another GSource, if its
+'prepare' function indicates readiness, then the parent's
+'prepare' function will never be run. The io_watch_poll_prepare
+absolutely *must* be run on every iteration of the main loop,
+to ensure that the chardev backend doesn't feed data to the
+frontend that it is unable to consume.
+
+At the time a7077b8e354d90fec26c2921aa2dea85b90dff90 was made,
+all the child GSource impls were relying on poll'ing an FD,
+so their 'prepare' functions would never indicate readiness
+ahead of poll() being invoked. So the buggy behaviour was
+not noticed and lay dormant.
+
+Relatively recently the QIOChannelTLS impl introduced a
+level 2 child GSource, which checks with GNUTLS whether it
+has cached any data that was decoded but not yet consumed:
+
+  commit ffda5db65aef42266a5053a4be34515106c4c7ee
+  Author: Antoine Damhet <antoine.damhet@shadow.tech>
+  Date:   Tue Nov 15 15:23:29 2022 +0100
+
+    io/channel-tls: fix handling of bigger read buffers
+
+    Since the TLS backend can read more data from the underlying QIOChannel
+    we introduce a minimal child GSource to notify if we still have more
+    data available to be read.
+

+
+With this, it is now quite common for the 'prepare' function
+on a QIOChannelTLS GSource to indicate immediate readiness,
+bypassing the parent GSource 'prepare' function. IOW, the
+critical 'io_watch_poll_prepare' is being skipped on some
+iterations of the main loop. As a result chardev frontend
+asserts are now being triggered as they are fed data they
+are not ready to consume.
+
+A reproducer is as follows:
+
+ * In terminal 1 run a GNUTLS *echo* server
+
+   $ gnutls-serv --echo \
+                 --x509cafile ca-cert.pem \
+                 --x509keyfile server-key.pem \
+		 --x509certfile server-cert.pem \
+		 -p 9000
+
+ * In terminal 2 run a QEMU guest
+
+   $ qemu-system-s390x \
+       -nodefaults \
+       -display none \
+       -object tls-creds-x509,id=tls0,dir=$PWD,endpoint=client \
+       -chardev socket,id=con0,host=localhost,port=9000,tls-creds=tls0 \
+       -device sclpconsole,chardev=con0 \
+       -hda Fedora-Cloud-Base-39-1.5.s390x.qcow2
+
+After the previous patch revert, but before this patch revert,
+this scenario will crash:
+
+  qemu-system-s390x: ../hw/char/sclpconsole.c:73: chr_read: Assertion
+  `size <= SIZE_BUFFER_VT220 - scon->iov_data_len' failed.
+
+This assert indicates that 'tcp_chr_read' was called without
+'tcp_chr_read_poll' having first been checked for ability to
+receive more data
+
+QEMU's use of a 'prepare' function to create/delete another
+GSource is rather a hack and not normally the kind of thing that
+is expected to be done by a GSource. There is no mechanism to
+force GLib to always run the 'prepare' function of a parent
+GSource. The best option is to simply not use the child source
+concept, and go back to the functional approach previously
+relied on.

-
-with Q35 using ACPI PCI hotplug by default, user's request to unplug
-device is ignored when it's issued before guest OS has been booted.
-And any additional attempt to request device hot-unplug afterwards
-results in following error:
-
-  "Device XYZ is already in the process of unplug"
-
-arguably it can be considered as a regression introduced by [2],
-before which it was possible to issue unplug request multiple
-times.
-
-Accept new uplug requests after timeout (1ms). This brings ACPI PCI
-hotplug on par with native PCIe unplug behavior [1] and allows user
-to repeat unplug requests at propper times.
-Set expire timeout to arbitrary 1msec so user won't be able to
-flood guest with SCI interrupts by calling device_del in tight loop.
-
-PS:
-ACPI spec doesn't mandate what OSPM can do with GPEx.status
-bits set before it's booted => it's impl. depended.
-Status bits may be retained (I tested with one Windows version)
-or cleared (Linux since 2.6 kernel times) during guest's ACPI
-subsystem initialization.
-Clearing status bits (though not wrong per se) hides the unplug
-event from guest, and it's upto user to repeat device_del later
-when guest is able to handle unplug requests.

+
+aio_context_acquire()/aio_context_release() has been replaced by
+fine-grained locking to protect state shared by multiple threads. The
+AioContext lock still plays the role of balancing locking in
+AIO_WAIT_WHILE() and many functions in QEMU either require that the
+AioContext lock is held or not held for this reason. In other words, the
+AioContext lock is purely there for consistency with itself and serves
+no real purpose anymore.
+
+Stop actually acquiring/releasing the lock in
+aio_context_acquire()/aio_context_release() so that subsequent patches
+can remove callers across the codebase incrementally.
+
+I have performed "make check" and qemu-iotests stress tests across
+x86-64, ppc64le, and aarch64 to confirm that there are no failures as a
+result of eliminating the lock.

+
+Delete these functions because nothing calls these functions anymore.
+
+I introduced these APIs in commit 98563fc3ec44 ("aio: add
+aio_context_acquire() and aio_context_release()") in 2014. It's with a
+sigh of relief that I delete these APIs almost 10 years later.
+
+Thanks to Paolo Bonzini's vision for multi-queue QEMU, we got an
+understanding of where the code needed to go in order to remove the
+limitations that the original dataplane and the IOThread/AioContext
+approach that followed it.
+
+Emanuele Giuseppe Esposito had the splendid determination to convert
+large parts of the codebase so that they no longer needed the AioContext
+lock. This was a painstaking process, both in the actual code changes
+required and the iterations of code review that Emanuele eked out of
+Kevin and me over many months.
+
+Kevin Wolf tackled multitudes of graph locking conversions to protect
+in-flight I/O from run-time changes to the block graph as well as the
+clang Thread Safety Analysis annotations that allow the compiler to
+check whether the graph lock is being used correctly.
+
+And me, well, I'm just here to add some pizzazz to the QEMU multi-queue
+block layer :). Thank you to everyone who helped with this effort,
+including Eric Blake, code reviewer extraordinaire, and others who I've
+forgotten to mention.

+RH-Commit: [20/26] 20e49777869714c99769263103f1b0c2c370cfcd (kmwolf/centos-qemu-kvm)
+
+Now that the AioContext lock no longer exists, AIO_WAIT_WHILE() and
+AIO_WAIT_WHILE_UNLOCKED() are equivalent.
+
+A future patch will get rid of AIO_WAIT_WHILE_UNLOCKED().

-    async: Add an optional reentrancy guard to the BH API
-
-    Devices can pass their MemoryReentrancyGuard (from their DeviceState),
-    when creating new BHes. Then, the async API will toggle the guard
-    before/after calling the BH call-back. This prevents bh->mmio reentrancy
-    issues.

-    A BH callback can free the BH, causing a use-after-free in aio_bh_call.
-    Fix that by keeping a local copy of the re-entrancy guard pointer.
-
-    Buglink: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=58513
-    Fixes: 9c86c97f12 ("async: Add an optional reentrancy guard to the BH API")

+RH-Commit: [20/67] 8a56344ab4a2126f248bfa492ccddd19265f39be (eauger1/centos-qemu-kvm)
+
+Introduce an iommufd object which allows the interaction
+with the host /dev/iommu device.
+
+The /dev/iommu can have been already pre-opened outside of qemu,
+in which case the fd can be passed directly along with the
+iommufd object:
+
+This allows the iommufd object to be shared accross several
+subsystems (VFIO, VDPA, ...). For example, libvirt would open
+the /dev/iommu once.
+
+If no fd is passed along with the iommufd object, the /dev/iommu
+is opened by the qemu code.

+
+Coverity reports a concurrent data access violation because be->users
+is being accessed in iommufd_backend_can_be_deleted() without holding
+the mutex.
+
+However, these routines are called from the QEMU main thread when a
+device is created. In this case, the code paths should be protected by
+the BQL lock and it should be safe to drop the IOMMUFD backend mutex.
+Simply remove it.

-
-When processing vectored guest requests that are not aligned to the
-storage request alignment, we pad them by adding head and/or tail
-buffers for a read-modify-write cycle.
-
-The guest can submit I/O vectors up to IOV_MAX (1024) in length, but
-with this padding, the vector can exceed that limit.  As of
-4c002cef0e9abe7135d7916c51abce47f7fc1ee2 ("util/iov: make
-qemu_iovec_init_extended() honest"), we refuse to pad vectors beyond the
-limit, instead returning an error to the guest.
-
-To the guest, this appears as a random I/O error.  We should not return
-an I/O error to the guest when it issued a perfectly valid request.
-
-Before 4c002cef0e9abe7135d7916c51abce47f7fc1ee2, we just made the vector
-longer than IOV_MAX, which generally seems to work (because the guest
-assumes a smaller alignment than we really have, file-posix's
-raw_co_prw() will generally see bdrv_qiov_is_aligned() return false, and
-so emulate the request, so that the IOV_MAX does not matter).  However,
-that does not seem exactly great.
-
-I see two ways to fix this problem:
-1. We split such long requests into two requests.
-2. We join some elements of the vector into new buffers to make it
-   shorter.
-
-I am wary of (1), because it seems like it may have unintended side
-effects.
-
-(2) on the other hand seems relatively simple to implement, with
-hopefully few side effects, so this patch does that.
-
-To do this, the use of qemu_iovec_init_extended() in bdrv_pad_request()
-is effectively replaced by the new function bdrv_create_padded_qiov(),
-which not only wraps the request IOV with padding head/tail, but also
-ensures that the resulting vector will not have more than IOV_MAX
-elements.  Putting that functionality into qemu_iovec_init_extended() is
-infeasible because it requires allocating a bounce buffer; doing so
-would require many more parameters (buffer alignment, how to initialize
-the buffer, and out parameters like the buffer, its length, and the
-original elements), which is not reasonable.
-
-Conversely, it is not difficult to move qemu_iovec_init_extended()'s
-functionality into bdrv_create_padded_qiov() by using public
-qemu_iovec_* functions, so that is what this patch does.
-
-Because bdrv_pad_request() was the only "serious" user of
-qemu_iovec_init_extended(), the next patch will remove the latter
-function, so the functionality is not implemented twice.

-
-bdrv_pad_request() relies on requests' lengths not to exceed SIZE_MAX,
-which bdrv_check_qiov_request() does not guarantee.
-
-bdrv_check_request32() however will guarantee this, and both of
-bdrv_pad_request()'s callers (bdrv_co_preadv_part() and
-bdrv_co_pwritev_part()) already run it before calling
-bdrv_pad_request().  Therefore, bdrv_pad_request() can safely call
-bdrv_check_request32() without expecting error, too.
-
-In effect, this patch will not change guest-visible behavior.  It is a
-clean-up to tighten a condition to match what is guaranteed by our
-callers, and which exists purely to show clearly why the subsequent
-assertion (`assert(*bytes <= SIZE_MAX)`) is always true.
-
-Note there is a difference between the interfaces of
-bdrv_check_qiov_request() and bdrv_check_request32(): The former takes
-an errp, the latter does not, so we can no longer just pass
-&error_abort.  Instead, we need to check the returned value.  While we
-do expect success (because the callers have already run this function),
-an assert(ret == 0) is not much simpler than just to return an error if
-it occurs, so let us handle errors by returning them up the stack now.

+
+    block: Parse filenames only when explicitly requested
+
+    When handling image filenames from legacy options such as -drive or from
+    tools, these filenames are parsed for protocol prefixes, including for
+    the json:{} pseudo-protocol.
+
+    This behaviour is intended for filenames that come directly from the
+    command line and for backing files, which may come from the image file
+    itself. Higher level management tools generally take care to verify that
+    untrusted images don't contain a bad (or any) backing file reference;
+    'qemu-img info' is a suitable tool for this.
+
+    However, for other files that can be referenced in images, such as
+    qcow2 data files or VMDK extents, the string from the image file is
+    usually not verified by management tools - and 'qemu-img info' wouldn't
+    be suitable because in contrast to backing files, it already opens these
+    other referenced files. So here the string should be interpreted as a
+    literal local filename. More complex configurations need to be specified
+    explicitly on the command line or in QMP.
+
+    This patch changes bdrv_open_inherit() so that it only parses filenames
+    if a new parameter parse_filename is true. It is set for the top level
+    in bdrv_open(), for the file child and for the backing file child. All
+    other callers pass false and disable filename parsing this way.

+
+RH-Author: Hanna Czenczek <hreitz@redhat.com>
+RH-MergeRequest: 222: Allow concurrent BlockBackend context changes
+RH-Jira: RHEL-24593
+RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
+RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
+RH-Commit: [1/2] 9e1b535f60f7afa94a0817dc3e71136e41631c71 (hreitz/qemu-kvm-c-9-s)
+
+Since AioContext locks have been removed, a BlockBackend's AioContext
+may really change at any time (only exception is that it is often
+confined to a drained section, as noted in this patch).  Therefore,
+blk_get_aio_context() cannot rely on its root node's context always
+matching that of the BlockBackend.
+
+In practice, whether they match does not matter anymore anyway: Requests
+can be sent to BDSs from any context, so anyone who requests the BB's
+context should have no reason to require the root node to have the same
+context.  Therefore, we can and should remove the assertion to that
+effect.
+
+In addition, because the context can be set and queried from different
+threads concurrently, it has to be accessed with atomic operations.

-
-qemu_open() in blkio_virtio_blk_common_open() is used to open the
-character device (e.g. /dev/vhost-vdpa-0 or /dev/vfio/vfio) or in
-the future eventually the unix socket.
-
-In all these cases we cannot open the path in read-only mode,
-when the `read-only` option of blockdev is on, because the exchange
-of IOCTL commands for example will fail.
-
-In order to open the device read-only, we have to use the `read-only`
-property of the libblkio driver as we already do in blkio_file_open().

-
-Until libblkio 1.3.0, virtio-blk drivers had completion eventfd
-notifications enabled from the start, but from the next releases
-this is no longer the case, so we have to explicitly enable them.
-
-In fact, the libblkio documentation says they could be disabled,
-so we should always enable them at the start if we want to be
-sure to get completion eventfd notifications:
-
-    By default, the driver might not generate completion events for
-    requests so it is necessary to explicitly enable the completion
-    file descriptor before use:
-
-    void blkioq_set_completion_fd_enabled(struct blkioq *q, bool enable);
-
-I discovered this while trying a development version of libblkio:
-the guest kernel hangs during boot, while probing the device.

-RH-Commit: [1/2] c85df95824f4889526a73527771dec9efcb06926 (stefanha/centos-stream-qemu-kvm)
-
-When QEMU is built with --enable-modules, the module_block.py script
-parses block/*.c to find block drivers that are built as modules. The
-script generates a table of block drivers called block_driver_modules[].
-This table is used for block driver module loading.
-
-The blkio.c driver uses macros to define its BlockDriver structs. This
-was done to avoid code duplication but the module_block.py script is
-unable to parse the macro. The result is that libblkio-based block
-drivers can be built as modules but will not be found at runtime.
-
-One fix is to make the module_block.py script or build system fancier so
-it can parse C macros (e.g. by parsing the preprocessed source code). I
-chose not to do this because it raises the complexity of the build,
-making future issues harder to debug.
-
-Keep things simple: use the macro to avoid duplicating BlockDriver
-function pointers but define .format_name and .protocol_name manually
-for each BlockDriver. This way the module_block.py is able to parse the
-code.
-
-Also get rid of the block driver name macros (e.g. DRIVER_IO_URING)
-because module_block.py cannot parse them either.
-

-
-libblkio 1.3.0 added support of "fd" property for virtio-blk-vhost-vdpa
-driver. In QEMU, starting from commit cad2ccc395 ("block/blkio: use
-qemu_open() to support fd passing for virtio-blk") we are using
-`blkio_get_int(..., "fd")` to check if the "fd" property is supported
-for all the virtio-blk-* driver.
-
-Unfortunately that property is also available for those driver that do
-not support it, such as virtio-blk-vhost-user.
-
-So, `blkio_get_int()` is not enough to check whether the driver supports
-the `fd` property or not. This is because the virito-blk common libblkio
-driver only checks whether or not `fd` is set during `blkio_connect()`
-and fails with -EINVAL for those transports that do not support it
-(all except vhost-vdpa for now).
-
-So let's handle the `blkio_connect()` failure, retrying it using `path`
-directly.

-
-Setting the `fd` property fails with virtio-blk-* libblkio drivers
-that do not support fd passing since
-https://gitlab.com/libblkio/libblkio/-/merge_requests/208.
-
-Getting the `fd` property, on the other hand, always succeeds for
-virtio-blk-* libblkio drivers even when they don't support fd passing.
-
-This patch switches to setting the `fd` property because it is a
-better mechanism for probing fd passing support than getting the `fd`
-property.

-The --enable-debug-graph-lock option is also enabled by the more general

+
+Use qemu_get_current_aio_context() in mixed wrappers and coroutine
+wrappers so that code runs in the caller's AioContext instead of moving
+to the BlockDriverState's AioContext. This change is necessary for the
+multi-queue block layer where any thread can call into the block layer.
+
+Most wrappers are IO_CODE where it's safe to use the current AioContext
+nowadays. BlockDrivers and the core block layer use their own locks and
+no longer depend on the AioContext lock for thread-safety.
+
+The bdrv_create() wrapper invokes GLOBAL_STATE code. Using the current
+AioContext is safe because this code is only called with the BQL held
+from the main loop thread.

+
+The file-posix block driver currently only sets up Linux AIO and
+io_uring in the BDS's AioContext. In the multi-queue block layer we must
+be able to submit I/O requests in AioContexts that do not have Linux AIO
+and io_uring set up yet since any thread can call into the block driver.
+
+Set up Linux AIO and io_uring for the current AioContext during request
+submission. We lose the ability to return an error from
+.bdrv_file_open() when Linux AIO and io_uring setup fails (e.g. due to
+resource limits). Instead the user only gets warnings and we fall back
+to aio=threads. This is still better than a fatal error after startup.

+
+The AioContext lock no longer exists.
+
+There is one noteworthy change:
+
+  - * More specifically, these functions use BDRV_POLL_WHILE(bs), which
+  - * requires the caller to be either in the main thread and hold
+  - * the BlockdriverState (bs) AioContext lock, or directly in the
+  - * home thread that runs the bs AioContext. Calling them from
+  - * another thread in another AioContext would cause deadlocks.
+  + * More specifically, these functions use BDRV_POLL_WHILE(bs), which requires
+  + * the caller to be either in the main thread or directly in the home thread
+  + * that runs the bs AioContext. Calling them from another thread in another
+  + * AioContext would cause deadlocks.
+
+I am not sure whether deadlocks are still possible. Maybe they have just
+moved to the fine-grained locks that have replaced the AioContext. Since
+I am not sure if the deadlocks are gone, I have kept the substance
+unchanged and just removed mention of the AioContext.

+
+    chardev/char-socket: Fix TLS io channels sending too much data to the backend
+
+    Commit ffda5db65a ("io/channel-tls: fix handling of bigger read buffers")
+    changed the behavior of the TLS io channels to schedule a second reading
+    attempt if there is still incoming data pending. This caused a regression
+    with backends like the sclpconsole that check in their read function that
+    the sender does not try to write more bytes to it than the device can
+    currently handle.
+
+    The problem can be reproduced like this:
+
+     1) In one terminal, do this:
+
+      mkdir qemu-pki
+      cd qemu-pki
+      openssl genrsa 2048 > ca-key.pem
+      openssl req -new -x509 -nodes -days 365000 -key ca-key.pem -out ca-cert.pem
+      # enter some dummy value for the cert
+      openssl genrsa 2048 > server-key.pem
+      openssl req -new -x509 -nodes -days 365000 -key server-key.pem \
+        -out server-cert.pem
+      # enter some other dummy values for the cert
+
+      gnutls-serv --echo --x509cafile ca-cert.pem --x509keyfile server-key.pem \
+                  --x509certfile server-cert.pem -p 8338
+
+     2) In another terminal, do this:
+
+      wget https://download.fedoraproject.org/pub/fedora-secondary/releases/39/Cloud/s390x/images/Fedora-Cloud-Base-39-1.5.s390x.qcow2
+
+      qemu-system-s390x -nographic -nodefaults \
+        -hda Fedora-Cloud-Base-39-1.5.s390x.qcow2 \
+        -object tls-creds-x509,id=tls0,endpoint=client,verify-peer=false,dir=$PWD/qemu-pki \
+        -chardev socket,id=tls_chardev,host=localhost,port=8338,tls-creds=tls0 \
+        -device sclpconsole,chardev=tls_chardev,id=tls_serial
+
+    QEMU then aborts after a second or two with:
+
+      qemu-system-s390x: ../hw/char/sclpconsole.c:73: chr_read: Assertion
+       `size <= SIZE_BUFFER_VT220 - scon->iov_data_len' failed.
+     Aborted (core dumped)
+
+    It looks like the second read does not trigger the chr_can_read() function
+    to be called before the second read, which should normally always be done
+    before sending bytes to a character device to see how much it can handle,
+    so the s->max_size in tcp_chr_read() still contains the old value from the
+    previous read. Let's make sure that we use the up-to-date value by calling
+    tcp_chr_read_poll() again here.

+
+The socket chardev often has 2 GSource object registered against the
+same FD. One is registered all the time and is just intended to handle
+POLLHUP events, while the other gets registered & unregistered on the
+fly as the frontend is ready to receive more data or not.
+
+It is very common for poll() to signal a POLLHUP event at the same time
+as there is pending incoming data from the disconnected client. It is
+therefore essential to process incoming data prior to processing HUP.
+The problem with having 2 GSource on the same FD is that there is no
+guaranteed ordering of execution between them, so the chardev code may
+process HUP first and thus discard data.
+
+This failure scenario is non-deterministic but can be seen fairly
+reliably by reverting a7077b8e354d90fec26c2921aa2dea85b90dff90, and
+then running 'tests/unit/test-char', which will sometimes fail with
+missing data.
+
+Ideally QEMU would only have 1 GSource, but that's a complex code
+refactoring job. The next best solution is to try to ensure ordering
+between the 2 GSource objects. This can be achieved by lowering the
+priority of the HUP GSource, so that it is never dispatched if the
+main GSource is also ready to dispatch. Counter-intuitively, lowering
+the priority of a GSource is done by raising its priority number.

+RH-Commit: [1/2] 5971de1c1e238457925bfb9c4bfc932de857b28d (stefanha/centos-stream-qemu-kvm)
+
+The coroutine pool implementation can hit the Linux vm.max_map_count
+limit, causing QEMU to abort with "failed to allocate memory for stack"
+or "failed to set up stack guard page" during coroutine creation.
+
+This happens because per-thread pools can grow to tens of thousands of
+coroutines. Each coroutine causes 2 virtual memory areas to be created.
+Eventually vm.max_map_count is reached and memory-related syscalls fail.
+The per-thread pool sizes are non-uniform and depend on past coroutine
+usage in each thread, so it's possible for one thread to have a large
+pool while another thread's pool is empty.
+
+Switch to a new coroutine pool implementation with a global pool that
+grows to a maximum number of coroutines and per-thread local pools that
+are capped at hardcoded small number of coroutines.
+
+This approach does not leave large numbers of coroutines pooled in a
+thread that may not use them again. In order to perform well it
+amortizes the cost of global pool accesses by working in batches of
+coroutines instead of individual coroutines.
+
+The global pool is a list. Threads donate batches of coroutines to when
+they have too many and take batches from when they have too few:
+
+.-----------------------------------.
+| Batch 1 | Batch 2 | Batch 3 | ... | global_pool
+`-----------------------------------'
+
+Each thread has up to 2 batches of coroutines:
+
+.-------------------.
+| Batch 1 | Batch 2 | per-thread local_pool (maximum 2 batches)
+`-------------------'
+
+The goal of this change is to reduce the excessive number of pooled
+coroutines that cause QEMU to abort when vm.max_map_count is reached
+without losing the performance of an adequately sized coroutine pool.
+
+Here are virtio-blk disk I/O benchmark results:

+
+Commit abfcd2760b3e ("dma-helpers: prevent dma_blk_cb() vs
+dma_aio_cancel() race") acquired the AioContext lock inside dma_blk_cb()
+to avoid a race with scsi_device_purge_requests() running in the main
+loop thread.
+
+The SCSI code no longer calls dma_aio_cancel() from the main loop thread
+while I/O is running in the IOThread AioContext. Therefore it is no
+longer necessary to take this lock to protect DMAAIOCB fields. The
+->cb() function also does not require the lock because blk_aio_*() and
+friends do not need the AioContext lock.
+
+Both hw/ide/core.c and hw/ide/macio.c also call dma_blk_io() but don't
+rely on it taking the AioContext lock, so this change is safe.

++===============================
++IOMMUFD BACKEND usage with VFIO
++===============================
++
++(Same meaning for backend/container/BE)
++
++With the introduction of iommufd, the Linux kernel provides a generic
++interface for user space drivers to propagate their DMA mappings to kernel
++for assigned devices. While the legacy kernel interface is group-centric,
++the new iommufd interface is device-centric, relying on device fd and iommufd.
++
++To support both interfaces in the QEMU VFIO device, introduce a base container
++to abstract the common part of VFIO legacy and iommufd container. So that the
++generic VFIO code can use either container.
++
++The base container implements generic functions such as memory_listener and
++address space management whereas the derived container implements callbacks
++specific to either legacy or iommufd. Each container has its own way to setup
++secure context and dma management interface. The below diagram shows how it
++looks like with both containers.

++  - vfio legacy BE: uses group fd and container fd to setup secure context
++    (set_container, set_iommu)
++
++* Device access
++
++  - iommufd BE: device fd is opened through ``/dev/vfio/devices/vfioX``
++  - vfio legacy BE: device fd is retrieved from group fd ioctl
++
++* DMA Mapping flow
++
++  1. VFIOAddressSpace receives MemoryRegion add/del via MemoryListener
++  2. VFIO populates DMA map/unmap via the container BEs
++     * iommufd BE: uses iommufd
++     * vfio legacy BE: uses container fd
++
++Example configuration
++=====================
++
++Step 1: configure the host device
++---------------------------------
++
++It's exactly same as the VFIO device with legacy VFIO container.
++
++Step 2: configure QEMU
++----------------------
++
++Interactions with the ``/dev/iommu`` are abstracted by a new iommufd
++object (compiled in with the ``CONFIG_IOMMUFD`` option).
++
++Any QEMU device (e.g. VFIO device) wishing to use ``/dev/iommu`` must
++be linked with an iommufd object. It gets a new optional property
++named iommufd which allows to pass an iommufd object. Take ``vfio-pci``
++device for example:
++
++.. code-block:: bash
++
++    -object iommufd,id=iommufd0
++    -device vfio-pci,host=0000:02:00.0,iommufd=iommufd0
++
++Note the ``/dev/iommu`` and VFIO cdev can be externally opened by a
++management layer. In such a case the fd is passed, the fd supports a
++string naming the fd or a number, for example:
++
++.. code-block:: bash
++
++    -object iommufd,id=iommufd0,fd=22
++    -device vfio-pci,iommufd=iommufd0,fd=23
++
++If the ``fd`` property is not passed, the fd is opened by QEMU.
++
++If no ``iommufd`` object is passed to the ``vfio-pci`` device, iommufd
++is not used and the user gets the behavior based on the legacy VFIO
++container:
++
++.. code-block:: bash
++
++    -device vfio-pci,host=0000:02:00.0
++
++Supported platform
++==================
++
++Supports x86, ARM and s390x currently.
++
++Caveats
++=======
++
++Dirty page sync
++---------------
++
++Dirty page sync with iommufd backend is unsupported yet, live migration is
++disabled by default. But it can be force enabled like below, low efficient
++though.
++
++.. code-block:: bash
++
++    -object iommufd,id=iommufd0
++    -device vfio-pci,host=0000:02:00.0,iommufd=iommufd0,enable-migration=on
++
++P2P DMA
++-------
++
++PCI p2p DMA is unsupported as IOMMUFD doesn't support mapping hardware PCI
++BAR region yet. Below warning shows for assigned PCI device, it's not a bug.
++
++.. code-block:: none
++
++    qemu-system-x86_64: warning: IOMMU_IOAS_MAP failed: Bad address, PCI BAR?
++    qemu-system-x86_64: vfio_container_dma_map(0x560cb6cb1620, 0xe000000021000, 0x3000, 0x7f32ed55c000) = -14 (Bad address)
++
++FD passing with mdev
++--------------------
++
++``vfio-pci`` device checks sysfsdev property to decide if backend is a mdev.
++If FD passing is used, there is no way to know that and the mdev is treated
++like a real PCI device. There is an error as below if user wants to enable
++RAM discarding for mdev.
++
++.. code-block:: none
++
++    qemu-system-x86_64: -device vfio-pci,iommufd=iommufd0,x-balloon-allowed=on,fd=9: vfio VFIO_FD9: x-balloon-allowed only potentially compatible with mdev devices
++
++``vfio-ap`` and ``vfio-ccw`` devices don't have same issue as their backend
++devices are always mdev and RAM discarding is force enabled.

-In QEMU 8.0, we've been seeing deadlocks in bdrv_graph_wrlock(). They
-come from callers that hold an AioContext lock, which is not allowed
-during polling. In theory, we could temporarily release the lock, but
-callers are inconsistent about whether they hold a lock, and if they do,
-some are also confused about which one they hold. While all of this is
-fixable, it's not trivial, and the best course of action for 8.0.1 is
-probably just disabling the graph locking code temporarily.
-
-We don't currently rely on graph locking yet. It is supposed to replace
-the AioContext lock eventually to enable multiqueue support, but as long
-as we still have the AioContext lock, it is sufficient without the graph
-lock. Once the AioContext lock goes away, the deadlock doesn't exist any
-more either and this commit can be reverted. (Of course, it can also be
-reverted while the AioContext lock still exists if the callers have been
-fixed.)

+
+https://issues.redhat.com/browse/RHEL-20341
+
+Let's implement the get_min_alignment() callback for memory devices, and
+copy for the device memory region the alignment of the host memory
+region. This mimics what virtio-mem does, and allows for re-introducing
+proper alignment checks for the memory region size (where we don't care
+about additional device requirements) in memory device core.

-i440fx machine versions 2.3 and newer supports dynamic ram
-resizing. See commit a1666142db6233 ("acpi-build: make ROMs RAM blocks resizeable") .
-Currently supported all q35 machine types (versions 2.4 and newer) supports
-resizable RAM/ROM blocks.Therefore the warning generated when the ACPI table
-size exceeds a pre-defined value does not apply to those machine versions.
-Add a check limiting the warning message to only those machines that does not
-support expandable ram blocks (that is, i440fx machines with version 2.2
-and older).

-
-Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2229133
-
-The implementation of the SMMUv3 has multiple places where it reads a
-data structure from the guest and directly operates on it without
-doing a guest-to-host endianness conversion.  Since all SMMU data
-structures are little-endian, this means that the SMMU doesn't work
-on a big-endian host.  In particular, this causes the Avocado test
-  machine_aarch64_virt.py:Aarch64VirtMachine.test_alpine_virt_tcg_gic_max
-to fail on an s390x host.
-
-Add appropriate byte-swapping on reads and writes of guest in-memory
-data structures so that the device works correctly on big-endian
-hosts.
-
-As part of this we constrain queue_read() to operate only on Cmd
-structs and queue_write() on Evt structs, because in practice these
-are the only data structures the two functions are used with, and we
-need to know what the data structure is to be able to byte-swap its
-parts correctly.

+
+Upstream: RHEL-only
+Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=57927352
+
+There are 3 high memory regions for GICv3 or GICv4 redistributor, PCI
+ECAM and PCI MMIO. Each of them has a property introduced by upstream
+commit 6a48c64eec ("hw/arm/virt: Add properties to disable high memory
+regions") so that the corresponding high memory region can be disabled.
+
+It's notable that another property ("compact-highmem") introduced by
+upstream commit f40408a9fe ("hw/arm/virt: Add 'compact-highmem' property")
+so that the compact high memory region layout during assignment can be
+disabled, compatible to the old machine types. However, we don't have
+the compatible issue since the compact high memory region layout is
+always kept as disabled until RHEL9.2.0 machine type and onwards.
+
+Expose those 3 properties: "highmem-redists", "highmem-ecam" and
+"highmem-mmio". The property "compact-highmem" is kept as hidden.

+RH-Commit: [1/1] bcdf6493bbd6d7b52b0b88ff44441d22aeddfde2 (eauger1/centos-qemu-kvm)
+
+arm_rhel_compat is not added for virt-rhel9.4.0 machine causing
+the efi-virtio.rom to be looked for when instantiating a virtio-net-pci
+device and it won't be found since not shipped on ARM. This is a
+regression compared to 9.2.
+
+Actually we do not need any rom file for any virtio-net-pci variant
+because edk2 already brings the functionality. So for 9.4 onwards, we
+want to set romfiles to "" for all of them.
+
+However at the moment we apply arm_rhel_compat from the latest
+rhel*_virt_options(). This is not aligned with the generic compat
+usage which sets compats for a given machine type to accomodate for
+changes that occured after its advent. Here we are somehow abusing
+the compat infra to set general driver options that should apply for
+all machines.  On top of that this is really error prone and we have
+forgotten to add arm_rhel_compat several times in the past.
+
+So let's introduce set_arm_rhel_compat() being called before any
+*virt_options in the non abstract machine class. That way the setting
+will apply to any machine type without any need to add it in any
+future machine types.
+
+For < 9.4 machines we don't really care keeping non void romfiles
+for transitional and non transitional devices because anyway this was
+not working. So let's keep things simple and apply the new defaults for
+all RHEL9 machine types.
+
+Finally, to follow the generic pattern we should set hw_compat_rhel_9_0
+in 9.0 machine as it is done on x86 or ccw. This has no consequence on
+aarch64 because it only contains x86 stuff but that helps understanding
+the consistency.

+Author: Bernhard Beschow <shentey@gmail.com>
+
+    Handling most of smbios data generation in the machine_done notifier is similar
+    to how the ARM virt machine handles it which also calls smbios_set_defaults()
+    there. The result is that all pc machines are freed from explicitly worrying
+    about smbios setup.

-
-Since it's implementation on v8.0.0-rc0, having the PCI_ERR_UNCOR_MASK
-set for machine types < 8.0 will cause migration to fail if the target
-QEMU version is < 8.0.0 :
-
-qemu-system-x86_64: get_pci_config_device: Bad config data: i=0x10a read: 40 device: 0 cmask: ff wmask: 0 w1cmask:0
-qemu-system-x86_64: Failed to load PCIDevice:config
-qemu-system-x86_64: Failed to load e1000e:parent_obj
-qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:02.0/e1000e'
-qemu-system-x86_64: load of migration failed: Invalid argument
-
-The above test migrated a 7.2 machine type from QEMU master to QEMU 7.2.0,
-with this cmdline:
-
-./qemu-system-x86_64 -M pc-q35-7.2 [-incoming XXX]
-
-In order to fix this, property x-pcie-err-unc-mask was introduced to
-control when PCI_ERR_UNCOR_MASK is enabled. This property is enabled by
-default, but is disabled if machine type <= 7.2.
-
-Fixes: 010746ae1d ("hw/pci/aer: Implement PCI_ERR_UNCOR_MASK register")

+RH-Commit: [47/67] c1a40cdab9bf62b16cb428d57a20b3e0eaa6de38 (eauger1/centos-qemu-kvm)
+
+When the legacy and iommufd backends were introduced, a set of common
+vfio-pci routines were exported in pci.c for both backends to use :
+
+  vfio_pci_pre_reset
+  vfio_pci_get_pci_hot_reset_info
+  vfio_pci_host_match
+  vfio_pci_post_reset
+
+This introduced a build failure on PPC when --without-default-devices
+is use because VFIO is always selected in ppc/Kconfig but VFIO_PCI is
+not.
+
+Use an 'imply VFIO_PCI' in ppc/Kconfig and bypass compilation of the
+VFIO EEH hooks routines defined in hw/ppc/spapr_pci_vfio.c with
+CONFIG_VFIO_PCI.

-    hw/scsi/lsi53c895a: Fix reentrancy issues in the LSI controller (CVE-2023-0330)
-
-    We cannot use the generic reentrancy guard in the LSI code, so
-    we have to manually prevent endless reentrancy here. The problematic
-    lsi_execute_script() function has already a way to detect whether
-    too many instructions have been executed - we just have to slightly
-    change the logic here that it also takes into account if the function
-    has been called too often in a reentrant way.
-
-    The code in fuzz-lsi53c895a-test.c has been taken from an earlier
-    patch by Mauro Matteo Cascella.
-
-    Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1563

-
-    hw/vfio/pci-quirks: Support alternate offset for GPUDirect Cliques
-
-    NVIDIA Turing and newer GPUs implement the MSI-X capability at the offset
-    previously reserved for use by hypervisors to implement the GPUDirect
-    Cliques capability.  A revised specification provides an alternate
-    location.  Add a config space walk to the quirk to check for conflicts,
-    allowing us to fall back to the new location or generate an error at the
-    quirk setup rather than when the real conflicting capability is added
-    should there be no available location.

-iteration we can get a stack out-of-band access. Initialize the
-output_size on each iteration.

-The issue was found with ASAN. Credits to:

-    i386/sev: Update checks and information related to reduced-phys-bits
-
-    The value of the reduced-phys-bits parameter is propogated to the CPUID
-    information exposed to the guest. Update the current validation check to
-    account for the size of the CPUID field (6-bits), ensuring the value is
-    in the range of 1 to 63.
-
-    Maintain backward compatibility, to an extent, by allowing a value greater
-    than 1 (so that the previously documented value of 5 still works), but not
-    allowing anything over 63.

+
+This replicates the scenario in which the bug was reported.
+Unfortunately this relies on actually executing a guest (so that the
+firmware initialises the virtio-blk device and moves it to its
+configured iothread), so this can't make use of the qtest accelerator
+like most other test cases. I tried to find a different easy way to
+trigger the bug, but couldn't find one.

-
-This tests that trying to resize an image with QMP block_resize doesn't
-hang or otherwise fail when the image is attached to a device running in
-an iothread.
-
-This is a regression test for the recent fix that changed
-qmp_block_resize, which is a coroutine based QMP handler, to avoid
-calling no_coroutine_fns directly.
