+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.

-    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.

-    block: introduce bdrv_open_file_child() helper
-
-    Almost all drivers call bdrv_open_child() similarly. Let's create a
-    helper for this.
-
-    The only not updated drivers that call bdrv_open_child() to set
-    bs->file are raw-format and snapshot-access:
-        raw-format sometimes want to have filtered child but
-            don't set drv->is_filter to true.
-        snapshot-access wants only DATA | PRIMARY
-
-    Possibly we should implement drv->is_filter_func() handler, to consider
-    raw-format as filter when it works as filter.. But it's another story.
-
-    Note also, that we decrease assignments to bs->file in code: it helps
-    us restrict modifying this field in further commit.

-    glib-compat: Introduce g_memdup2() wrapper
-    When experimenting raising GLIB_VERSION_MIN_REQUIRED to 2.68
-    (Fedora 34 provides GLib 2.68.1) we get:
-
-      hw/virtio/virtio-crypto.c:245:24: error: 'g_memdup' is deprecated: Use 'g_memdup2' instead [-Werror,-Wdeprecated-declarations]
-      ...
-
-    g_memdup() has been updated by g_memdup2() to fix eventual security
-    issues (size argument is 32-bit and could be truncated / wrapping).
-    GLib recommends to copy their static inline version of g_memdup2():
-    https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538
-
-    Our glib-compat.h provides a comment explaining how to deal with
-    these deprecated declarations (see commit e71e8cc0355
-    "glib: enforce the minimum required version and warn about old APIs").
-
-    Following this comment suggestion, implement the g_memdup2_qemu()
-    wrapper to g_memdup2(), and use the safer equivalent inlined when
-    we are using pre-2.68 GLib.

- virtio-net-pci variants
-
-RH-Author: Eric Auger <eric.auger@redhat.com>
-RH-MergeRequest: 344: hw/arm/virt: Do not load efi-virtio.rom for any virtio-net-pci variants
-RH-Jira: RHEL-14870
-RH-Acked-by: Gerd Hoffmann <None>
-RH-Acked-by: Sebastian Ott <None>
-RH-Commit: [1/1] ffeaa78ad0a1cff5b49009dfb32d25e5cadc0e05
-
-Upstream: RHEL-only
-Brew: http://brewweb.engineering.redhat.com/brew/taskinfo?taskID=5785640
-
-Currently arm_rhel_compat just sets the romfile to "" for
-virtio-net-pci and not for transitional and non transitional
-variants. However, on aarch64 RHEL, efi-virtio.rom is not
-shipped so transitional and non-transitional variants cannot
-be used and the following error is obeserved:
-
-"Could not open option rom 'efi-virtio.rom': No such file or directory"
-
-In practice, we do not need any rom file for those virtio-net-pci
-variants either because edk2 already brings the full functionality.
-
-So let's change the applied compat to cover all the variants. While
-at it also change the way arm_rhel_compat is applied. Instead of
-applying it from the latest _virt_options(), which is error prone
-when upgrading the machine type, let's apply it before calling
-*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.
-
-We don't really care keeping non void romfiles for transitional and
-non transitional devices on previous machine types because this
-was not working anyway.

-    hw/ide: reset: cancel async DMA operation before resetting state
-
-    If there is a pending DMA operation during ide_bus_reset(), the fact
-    that the IDEState is already reset before the operation is canceled
-    can be problematic. In particular, ide_dma_cb() might be called and
-    then use the reset IDEState which contains the signature after the
-    reset. When used to construct the IO operation this leads to
-    ide_get_sector() returning 0 and nsector being 1. This is particularly
-    bad, because a write command will thus destroy the first sector which
-    often contains a partition table or similar.
-
-    Traces showing the unsolicited write happening with IDEState
-    0x5595af6949d0 being used after reset:
-

-    hw/s390x: Move KVM specific PV from hw/ to target/s390x/kvm/
-
-    Protected Virtualization (PV) is not a real hardware device:
-    it is a feature of the firmware on s390x that is exposed to
-    userspace via the KVM interface.
-
-    Move the pv.c/pv.h files to target/s390x/kvm/ to make this clearer.

-RH-Commit: [4/4] 4974a32174abefb509b7c46671a364b4b991449e
-
-Since commit effd60c8 changed how QMP commands are processed, the order
-of the block-commit return value and job events in iotests 144 wasn't
-fixed and more and caused the test to fail intermittently.
-
-Change the test to cache events first and then print them in a
-predefined order.
-
-Waiting three times for JOB_STATUS_CHANGE is a bit uglier than just
-waiting for the JOB_STATUS_CHANGE that has "status": "ready", but the
-tooling we have doesn't seem to allow the latter easily.
-

-RH-Commit: [2/4] ff0899262544b1b61b4c7de2eb798b664fe5202e
-
-The common.qemu bash functions allow tests to interact with the QMP
-monitor of a QEMU process. I spent two days trying to update 141 when
-the order of the test output changed, but found it would still fail
-occassionally because printf() and QMP events race with synchronous QMP
-communication.
-
-I gave up and ported 141 to the existing Python API for QMP tests. The
-Python API is less affected by the order in which QEMU prints output
-because it does not print all QMP traffic by default.
-
-The next commit changes the order in which QMP messages are received.
-Make 141 reliable first.

-iothreads, adding coverage the fix to qio channels made in the
-previous patch.
-
-The shell function pick_unused_port() was copied from
-nbdkit.git/tests/functions.sh.in, where it had all authors from Red
-Hat, agreeing to the resulting relicensing from 2-clause BSD to GPLv2.

-Commit 3e7ef738 plugged the use-after-free of the global nbd_server
-object, but overlooked a use-after-free of nbd_server->listener.
-Although this race is harder to hit, notice that our shutdown path
-first drops the reference count of nbd_server->listener, then triggers
-actions that can result in a pending client reaching the
-nbd_blockdev_client_closed() callback, which in turn calls
-qio_net_listener_set_client_func on a potentially stale object.
-
-If we know we don't want any more clients to connect, and have already
-told the listener socket to shut down, then we should not be trying to
-update the listener socket's associated function.

-
-Allowing an unlimited number of clients to any web service is a recipe
-for a rudimentary denial of service attack: the client merely needs to
-open lots of sockets without closing them, until qemu no longer has
-any more fds available to allocate.
-
-For qemu-nbd, we default to allowing only 1 connection unless more are
-explicitly asked for (-e or --shared); this was historically picked as
-a nice default (without an explicit -t, a non-persistent qemu-nbd goes
-away after a client disconnects, without needing any additional
-follow-up commands), and we are not going to change that interface now
-(besides, someday we want to point people towards qemu-storage-daemon
-instead of qemu-nbd).
-
-But for qemu proper, and the newer qemu-storage-daemon, the QMP
-nbd-server-start command has historically had a default of unlimited
-number of connections, in part because unlike qemu-nbd it is
-inherently persistent until nbd-server-stop.  Allowing multiple client
-sockets is particularly useful for clients that can take advantage of
-MULTI_CONN (creating parallel sockets to increase throughput),
-although known clients that do so (such as libnbd's nbdcopy) typically
-use only 8 or 16 connections (the benefits of scaling diminish once
-more sockets are competing for kernel attention).  Picking a number
-large enough for typical use cases, but not unlimited, makes it
-slightly harder for a malicious client to perform a denial of service
-merely by opening lots of connections withot progressing through the
-handshake.
-
-This change does not eliminate CVE-2024-7409 on its own, but reduces
-the chance for fd exhaustion or unlimited memory usage as an attack
-surface.  On the other hand, by itself, it makes it more obvious that
-with a finite limit, we have the problem of an unauthenticated client
-holding 100 fds opened as a way to block out a legitimate client from
-being able to connect; thus, later patches will further add timeouts
-to reject clients that are not making progress.
-
-This is an INTENTIONAL change in behavior, and will break any client
-of nbd-server-start that was not passing an explicit max-connections
-parameter, yet expects more than 100 simultaneous connections.  We are
-not aware of any such client (as stated above, most clients aware of
-MULTI_CONN get by just fine on 8 or 16 connections, and probably cope
-with later connections failing by relying on the earlier connections;
-libvirt has not yet been passing max-connections, but generally
-creates NBD servers with the intent for a single client for the sake
-of live storage migration; meanwhile, the KubeSAN project anticipates
-a large cluster sharing multiple clients [up to 8 per node, and up to
-100 nodes in a cluster], but it currently uses qemu-nbd with an
-explicit --shared=0 rather than qemu-storage-daemon with
-nbd-server-start).
-
-We considered using a deprecation period (declare that omitting
-max-parameters is deprecated, and make it mandatory in 3 releases -
-then we don't need to pick an arbitrary default); that has zero risk
-of breaking any apps that accidentally depended on more than 100
-connections, and where such breakage might not be noticed under unit
-testing but only under the larger loads of production usage.  But it
-does not close the denial-of-service hole until far into the future,
-and requires all apps to change to add the parameter even if 100 was
-good enough.  It also has a drawback that any app (like libvirt) that
-is accidentally relying on an unlimited default should seriously
-consider their own CVE now, at which point they are going to change to
-pass explicit max-connections sooner than waiting for 3 qemu releases.
-Finally, if our changed default breaks an app, that app can always
-pass in an explicit max-parameters with a larger value.
-
-It is also intentional that the HMP interface to nbd-server-start is
-not changed to expose max-connections (any client needing to fine-tune
-things should be using QMP).

-RH-Commit: [4/4] 92a20764dbee3cf94181cab412d90cbf92b4a417 (ebblake/qemu-kvm)
-
-A malicious client can attempt to connect to an NBD server, and then
-intentionally delay progress in the handshake, including if it does
-not know the TLS secrets.  Although the previous two patches reduce
-this behavior by capping the default max-connections parameter and
-killing slow clients, they did not eliminate the possibility of a
-client waiting to close the socket until after the QMP nbd-server-stop
-command is executed, at which point qemu would SEGV when trying to
-dereference the NULL nbd_server global which is no longer present.
-This amounts to a denial of service attack.  Worse, if another NBD
-server is started before the malicious client disconnects, I cannot
-rule out additional adverse effects when the old client interferes
-with the connection count of the new server (although the most likely
-is a crash due to an assertion failure when checking
-nbd_server->connections > 0).
-
-For environments without this patch, the CVE can be mitigated by
-ensuring (such as via a firewall) that only trusted clients can
-connect to an NBD server.  Note that using frameworks like libvirt
-that ensure that TLS is used and that nbd-server-stop is not executed
-while any trusted clients are still connected will only help if there
-is also no possibility for an untrusted client to open a connection
-but then stall on the NBD handshake.
-
-Given the previous patches, it would be possible to guarantee that no
-clients remain connected by having nbd-server-stop sleep for longer
-than the default handshake deadline before finally freeing the global
-nbd_server object, but that could make QMP non-responsive for a long
-time.  So intead, this patch fixes the problem by tracking all client
-sockets opened while the server is running, and forcefully closing any
-such sockets remaining without a completed handshake at the time of
-nbd-server-stop, then waiting until the coroutines servicing those
-sockets notice the state change.  nbd-server-stop now has a second
-AIO_WAIT_WHILE_UNLOCKED (the first is indirectly through the
-blk_exp_close_all_type() that disconnects all clients that completed
-handshakes), but forced socket shutdown is enough to progress the
-coroutines and quickly tear down all clients before the server is
-freed, thus finally fixing the CVE.
-
-This patch relies heavily on the fact that nbd/server.c guarantees
-that it only calls nbd_blockdev_client_closed() from the main loop
-(see the assertion in nbd_client_put() and the hoops used in
-nbd_client_put_nonzero() to achieve that); if we did not have that
-guarantee, we would also need a mutex protecting our accesses of the
-list of connections to survive re-entrancy from independent iothreads.
-
-Although I did not actually try to test old builds, it looks like this
-problem has existed since at least commit 862172f45c (v2.12.0, 2017) -
-even back when that patch started using a QIONetListener to handle
-listening on multiple sockets, nbd_server_free() was already unaware
-that the nbd_blockdev_client_closed callback can be reached later by a
-client thread that has not completed handshakes (and therefore the
-client's socket never got added to the list closed in
-nbd_export_close_all), despite that patch intentionally tearing down
-the QIONetListener to prevent new clients.

-RH-Commit: [3/4] 8c39829f8efbded9af018a4b915af266a55a793a (ebblake/qemu-kvm)
-
-A client that opens a socket but does not negotiate is merely hogging
-qemu's resources (an open fd and a small amount of memory); and a
-malicious client that can access the port where NBD is listening can
-attempt a denial of service attack by intentionally opening and
-abandoning lots of unfinished connections.  The previous patch put a
-default bound on the number of such ongoing connections, but once that
-limit is hit, no more clients can connect (including legitimate ones).
-The solution is to insist that clients complete handshake within a
-reasonable time limit, defaulting to 10 seconds.  A client that has
-not successfully completed NBD_OPT_GO by then (including the case of
-where the client didn't know TLS credentials to even reach the point
-of NBD_OPT_GO) is wasting our time and does not deserve to stay
-connected.  Later patches will allow fine-tuning the limit away from
-the default value (including disabling it for doing integration
-testing of the handshake process itself).
-
-Note that this patch in isolation actually makes it more likely to see
-qemu SEGV after nbd-server-stop, as any client socket still connected
-when the server shuts down will now be closed after 10 seconds rather
-than at the client's whims.  That will be addressed in the next patch.
-
-For a demo of this patch in action:
-$ qemu-nbd -f raw -r -t -e 10 file &
-$ nbdsh --opt-mode -c '
-H = list()
-for i in range(20):
-  print(i)
-  H.insert(i, nbd.NBD())
-  H[i].set_opt_mode(True)
-  H[i].connect_uri("nbd://localhost")
-'
-$ kill $!
-
-where later connections get to start progressing once earlier ones are
-forcefully dropped for taking too long, rather than hanging.

-RH-Commit: [1/3] 6ec0ef287fbc976175da83a0c14d9878e83affa2 (ebblake/qemu-kvm)
-
-DOWNSTREAM ONLY - but based on an idea originally included as a
-side-effect in the larger upstream patch 06e0f098 "io: follow
-coroutine AioContext in qio_channel_yield()", as well as handling the
-state of the qio TLS channel before it is associated with a block
-device as an alternative to 199e84de "qio: Inherit
-follow_coroutine_ctx across TLS".
-
-The NBD server code wants to use qio_channel_shutdown() followed by
-AIO_WAIT_WHILE() during nbd_server_free(), but cannot attach the ioc
-to an AioContext until the client has completed the handshake to the
-point that the server knows what block device to associate with the
-connection.  The qio code is set up to handle connections with no
-AioContext in the iohandler context, but this context is specifically
-designed to NOT make progress during AIO_WAIT_WHILE().  In order to
-prevent things from deadlocking, the qio channels handling NBD
-handshake MUST be in the qemu_aio_context, so that an early shutdown
-triggered by nbd-server-stop can make progress.
-
-Note that upstream handled the main qio channel by the use of
-qio_channel_set_follow_coroutine_ctx() in only one place in
-nbd/server.c; upstream handled the TLS channel by a more generic
-second patch that taught qio TLS channel to inherit the
-follow_coroutine_ctx status from its parent.  But since this patch is
-already downstream only, the minimal diff is achieved by manually
-setting the status of the TLS channel in NBD code, rather than
-backporting the qio inheritance code.  For testing that the second
-call to qio_channel_set_favor_qemu_aio_ctx() matters, I used this test
-setup (borrowing a pre-built PSK file for username alice from the
-libnbd project, and using IPv4 since this qemu is too old to support
-TLS over Unix sockets):
-
-$ # in terminal 1:
-$ qemu-system-x86_64 --nographic --nodefaults --qmp stdio \
-  --object tls-creds-psk,id=tls0,dir=/PATHTO/libnbd/tests,endpoint=server
-{"execute": "qmp_capabilities"}
-{"execute":"nbd-server-start","arguments":{"addr":{"type":"inet",
-  "data":{"host":"127.0.0.1","port":"10809"}},"tls-creds":"tls0"}}
-
-$ # in terminal 2:
-$ nbdsh -c 'h.set_uri_allow_local_file(True)' --opt-mode -u \
-  'nbds://alice@127.0.0.1/?tls-psk-file=/PATHTO/libnbd/tests/keys.psk' \
-  -c 'import time; time.sleep(15)'
-
-$ # in terminal 1, before 10 seconds elapse
-{"execute":"nbd-server-stop"}
-{"execute":"quit"}
-
-and observed that, when omitting the one-line TLS setting, qemu would
-hit the same deadlock with a TLS client as what I was observing for a
-non-TLS client without this entire patch.

-
-Upcoming patches to fix a CVE need to track an opaque pointer passed
-in by the owner of a client object, as well as request for a time
-limit on how fast negotiation must complete.  Prepare for that by
-changing the signature of nbd_client_new() and adding an accessor to
-get at the opaque pointer, although for now the two servers
-(qemu-nbd.c and blockdev-nbd.c) do not change behavior even though
-they pass in a new default timeout value.

-    net: Provide MemReentrancyGuard * to qemu_new_nic()
-
-    Recently MemReentrancyGuard was added to DeviceState to record that the
-    device is engaging in I/O. The network device backend needs to update it
-    when delivering a packet to a device.
-
-    In preparation for such a change, add MemReentrancyGuard * as a
-    parameter of qemu_new_nic().

-    net: Update MemReentrancyGuard for NIC
-
-    Recently MemReentrancyGuard was added to DeviceState to record that the
-    device is engaging in I/O. The network device backend needs to update it
-    when delivering a packet to a device.
-
-    This implementation follows what bottom half does, but it does not add
-    a tracepoint for the case that the network device backend started
-    delivering a packet to a device which is already engaging in I/O. This
-    is because such reentrancy frequently happens for
-    qemu_flush_queued_packets() and is insignificant.

-    qcow2: Don't open data_file with BDRV_O_NO_IO
-
-    One use case for 'qemu-img info' is verifying that untrusted images
-    don't reference an unwanted external file, be it as a backing file or an
-    external data file. To make sure that calling 'qemu-img info' can't
-    already have undesired side effects with a malicious image, just don't
-    open the data file at all with BDRV_O_NO_IO. If nothing ever tries to do
-    I/O, we don't need to have it open.
-
-    This changes the output of iotests case 061, which used 'qemu-img info'
-    to show that opening an image with an invalid data file fails. After
-    this patch, it succeeds. Replace this part of the test with a qemu-io
-    call, but keep the final 'qemu-img info' to show that the invalid data
-    file is correctly displayed in the output.

-
-Bound APQNs have to be reset before tearing down the secure config via
-s390_machine_unprotect(). Otherwise the Ultravisor will return a error
-code.
-
-So let's do a subsystem_reset() which includes a AP reset before the
-unprotect call. We'll do a full device_reset() afterwards which will
-reset some devices twice. That's ok since we can't move the
-device_reset() before the unprotect as it includes a CPU clear reset
-which the Ultravisor does not expect at that point in time.

-    s390x/pci: avoid double enable/disable of aif
-
-    Use a flag to keep track of whether AIF is currently enabled.  This can be
-    used to avoid enabling/disabling AIF multiple times as well as to determine
-    whether or not it should be disabled during reset processing.

-    s390x/pci: drive ISM reset from subsystem reset
-
-    ISM devices are sensitive to manipulation of the IOMMU, so the ISM device
-    needs to be reset before the vfio-pci device is reset (triggering a full
-    UNMAP).  In order to ensure this occurs, trigger ISM device resets from
-    subsystem_reset before triggering the PCI bus reset (which will also
-    trigger vfio-pci reset).  This only needs to be done for ISM devices
-    which were enabled for use by the guest.
-    Further, ensure that AIF is disabled as part of the reset event.
-
-    Fixes: ef1535901a ("s390x: do a subsystem reset before the unprotect on reboot")
-    Fixes: 03451953c7 ("s390x/pci: reset ISM passthrough devices on shutdown and system reset")

-    s390x/pci: refresh fh before disabling aif
-
-    Typically we refresh the host fh during CLP enable, however it's possible
-    that the device goes through multiple reset events before the guest
-    performs another CLP enable.  Let's handle this for now by refreshing the
-    host handle from vfio before disabling aif.

-Enabling AP-passthrough(AP-pt) for PV-guest by using the new CPU
-features for PV-AP-pt of KVM.
-
-As usual QEMU first checks which CPU features are available and then
-sets them if available and selected by user. An additional check is done
-to verify that PV-AP can only be enabled if "regular" AP-pt is enabled
-as well. Note that KVM itself does not enforce this restriction.

-    target/s390x/arch_dump: Add arch cleanup function for PV dumps
-
-    PV dumps block vcpu runs until dump end is reached. If there's an
-    error between PV dump init and PV dump end the vm will never be able
-    to run again. One example of such an error is insufficient disk space
-    for the dump file.
-
-    Let's add a cleanup function that tries to do a dump end. The dump
-    completion data is discarded but there's no point in writing it to a
-    file anyway if there's a possibility that other PV dump data is
-    missing.

-kvm_s390_set_attr() is a misleading name as it only sets attributes for
-the KVM_S390_VM_CRYPTO group. Therefore, rename it to
-kvm_s390_set_crypto_attr().
-
-Add new functions ap_available() and ap_enabled() to avoid code
-duplication later.

-    target/s390x/kvm/pv: Provide some more useful information if decryption fails
-
-    It's a common scenario to copy guest images from one host to another
-    to run the guest on the other machine. This (of course) does not work
-    with "secure execution" guests since they are encrypted with one certain
-    host key. However, if you still (accidentally) do it, you only get a
-    very user-unfriendly error message that looks like this:
-
-     qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed:
-      header rc 108 rrc 5 IOCTL rc: -22
-
-    Let's provide at least a somewhat nicer hint to the users so that they
-    are able to figure out what might have gone wrong.

-    tests/qtest: ahci-test: add test exposing reset issue with pending callback
-
-    Before commit "hw/ide: reset: cancel async DMA operation before
-    resetting state", this test would fail, because a reset with a
-    pending write operation would lead to an unsolicited write to the
-    first sector of the disk.
-
-    The test writes a pattern to the beginning of the disk and verifies
-    that it is still intact after a reset with a pending operation. It
-    also checks that the pending operation actually completes correctly.

-Upstream: Merged
-Conflicts:
-         - The function g_memdup2() is used by this commit, but is not present in
-           this code version. It looks safe to introduce it in a preceding commit,
-           instead of reverting to the less safe g_memdup(), so that is what we do.
-         - There is a second upstream commit covering this CVE:
-           commit 9c416582611b ("ui/clipboard: add asserts for update and request")
-           which is based on several other previous commits not present in this version.
-           Re-applying these, or trying to adapt the code, is too intrusive and risky
-           given that it only introduces two diagnostic asserts which are not essential
-           for solving the CVE.
-           We therefore omit that commit.

-Date:   Wed Jan 24 11:57:48 2024 +0100

-    ui/clipboard: mark type as not available when there is no data
-
-    With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
-    message with len=0. In qemu_clipboard_set_data(), the clipboard info
-    will be updated setting data to NULL (because g_memdup(data, size)
-    returns NULL when size is 0). If the client does not set the
-    VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
-    the 'request' callback for the clipboard peer is not initialized.
-    Later, because data is NULL, qemu_clipboard_request() can be reached
-    via vdagent_chr_write() and vdagent_clipboard_recv_request() and
-    there, the clipboard owner's 'request' callback will be attempted to
-    be called, but that is a NULL pointer.
-
-    In particular, this can happen when using the KRDC (22.12.3) VNC
-    client.
-
-    Another scenario leading to the same issue is with two clients (say
-    noVNC and KRDC):
-
-    The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
-    initializes its cbpeer.
-
-    The KRDC client does not, but triggers a vnc_client_cut_text() (note
-    it's not the _ext variant)). There, a new clipboard info with it as
-    the 'owner' is created and via qemu_clipboard_set_data() is called,
-    which in turn calls qemu_clipboard_update() with that info.
-
-    In qemu_clipboard_update(), the notifier for the noVNC client will be
-    called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
-    noVNC client. The 'owner' in that clipboard info is the clipboard peer
-    for the KRDC client, which did not initialize the 'request' function.
-    That sounds correct to me, it is the owner of that clipboard info.
-
-    Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
-    the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
-    passes), that clipboard info is passed to qemu_clipboard_request() and
-    the original segfault still happens.
-
-    Fix the issue by handling updates with size 0 differently. In
-    particular, mark in the clipboard info that the type is not available.
-
-    While at it, switch to g_memdup2(), because g_memdup() is deprecated.

-    ui/vnc-clipboard: fix infinite loop in inflate_buffer (CVE-2023-3255)
-
-    A wrong exit condition may lead to an infinite loop when inflating a
-    valid zlib buffer containing some extra bytes in the `inflate_buffer`
-    function. The bug only occurs post-authentication. Return the buffer
-    immediately if the end of the compressed data has been reached
-    (Z_STREAM_END).

-    virtio-gpu: reset gfx resources in main thread
-
-    Calling OpenGL from different threads can have bad consequences if not
-    carefully reviewed. It's not generally supported. In my case, I was
-    debugging a crash in glDeleteTextures from OPENGL32.DLL, where I asked
-    qemu for gl=es, and thus ANGLE implementation was expected. libepoxy did
-    resolution of the global pointer for glGenTexture to the GLES version
-    from the main thread. But it resolved glDeleteTextures to the GL
-    version, because it was done from a different thread without correct
-    context. Oops.
-
-    Let's stick to the main thread for GL calls by using a BH.
-
-    Note: I didn't use atomics for reset_finished check, assuming the BQL
-    will provide enough of sync, but I might be wrong.

-    virtio-net: correctly copy vnet header when flushing TX
-
-    When HASH_REPORT is negotiated, the guest_hdr_len might be larger than
-    the size of the mergeable rx buffer header. Using
-    virtio_net_hdr_mrg_rxbuf during the header swap might lead a stack
-    overflow in this case. Fixing this by using virtio_net_hdr_v1_hash
-    instead.
