QEMU 8.2.2 required many changes, in particular to the alloc-track
block driver. It should be the same as [0] just with backup fleecing
patches added in. See the patch for details.
The only bigger change in QEMU 9.0.0 is that the AioContext locking
was removed, and it just required dropping the calls to acquire and
release the lock. See the patch for details.
Did not see any outstanding important fixes on the qemu-stable mailing
list currently, so none picked up.

Namely, it's also necessary to remove .dts source files from the
meson.build file, because the .dtb file names are not directly listed
anymore since commit 6e0dc9d2a8 ("meson: compile bundled device
trees").
The same commit also introduced a "'.dtb'" in a line not just listing
a file name and removing that line would break the script. Be more
precise and require an alphanumeric character before the suffix.

Same rationale as 6facdf3 ("also exclude hppa-firmware.img ROM from
build"), not used by Proxmox VE and would cause a failure during
build.

This version includes both the AioContext lock and the block graph
lock, so there might be some deadlocks lurking. It's not possible to
disable the block graph lock like was done in QEMU 8.1, because there
are no changes like the function bdrv_schedule_unref() that require
it. QEMU 9.0 will finally get rid of the AioContext locking.
During live-restore with a VirtIO SCSI drive with iothread there is a
known racy deadlock related to the AioContext lock. Not new [1], but
not sure if more likely now. Should be fixed in QEMU 9.0.
The block graph lock comes with annotations that can be checked by
clang's TSA. This required changes to the block drivers, i.e.
alloc-track, pbs, zeroinit as well as taking the appropriate locks
in pve-backup, savevm-async, vma-reader.
Local variable shadowing is prohibited via a compiler flag now,
required slight adaptation in vma.c.
Major changes only affect alloc-track:
* It is not possible to call a generated co-wrapper like
bdrv_get_info() while holding the block graph lock exclusively [0],
which does happen during initialization of alloc-track when the
backing hd is set and the refresh_limits driver callback is invoked.
The bdrv_get_info() call to get the cluster size is moved to
directly after opening the file child in track_open().
The important thing is that at least the request alignment for the
write target is used, because then the RMW cycle in bdrv_pwritev
will gather enough data from the backing file. Partial cluster
allocations in the target are not a fundamental issue, because the
driver returns its allocation status based on the bitmap, so any
other data that maps to the same cluster will still be copied later
by a stream job (or during writes to that cluster).
* Replacing the node cannot be done in the
track_co_change_backing_file() callback, because it is a coroutine
and cannot hold the block graph lock exclusively. So it is moved to
the stream job itself with the auto-remove option not having an
effect anymore (qemu-server would always set it anyways).
In the future, there could either be a special option for the stream
job, or maybe the upcoming blockdev-replace QMP command can be used.
Replacing the backing child is actually already done in the stream
job, so no need to do it in the track_co_change_backing_file()
callback. It also cannot be called from a coroutine. Looking at the
implementation in the qcow2 driver, it doesn't seem to be intended
to change the backing child itself, just update driver-internal
state.
Other changes:
* alloc-track: Error out early when used without auto-remove. Since
replacing the node now happens in the stream job, where the option
cannot be read from (it's internal to the driver), it will always be
treated as 'on'. Makes sure to have users beside qemu-server notice
the change (should they even exist). The option can be fully dropped
in the future while adding a version guard in qemu-server.
* alloc-track: Avoid seemingly superfluous child permission update.
Doesn't seem necessary nowadays (maybe after commit "alloc-track:
fix deadlock during drop" where the dropping is not rescheduled and
delayed anymore or some upstream change). Replacing the block node
will already update the permissions of the new node (which was the
file child before). Should there really be some issue, instead of
having a drop state, this could also be just based off the fact
whether there is still a backing child.
Dumping the cumulative (shared) permissions for the BDS with a debug
print yields the same values after this patch and with QEMU 8.1,
namely 3 and 5.
* PBS block driver: compile unconditionally. Proxmox VE always needs
it and something in the build process changed to make it not enabled
by default. Probably would need to move the build option to meson
otherwise.
* backup: job unreferencing during cleanup needs to happen outside of
coroutine, so it was moved to before invoking the clean
* mirror: Cherry-pick stable fix to avoid potential deadlock.
* savevm-async: migrate_init now can fail, so propagate potential
error.
* savevm-async: compression counters are not accessible outside
migration/ram-compress now, so drop code that prophylactically set
it to zero.

-Subject: [PATCH] Revert "Revert "graph-lock: Disable locking for now""
-
-This reverts commit 3cce22defb4b0e47cf135444e30cc673cff5ebad.
-
-There are still some issues with graph locking, e.g. deadlocks during
-backup canceling [0]. Because the AioContext locks still exist, it
-should be safe to disable locking again.
-
-From the original 80fc5d2600 ("graph-lock: Disable locking for now"):
-
-> 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.)

-Subject: [PATCH] migration states: workaround snapshot performance regression
-
-Commit 813cd616 ("migration: Use migration_transferred_bytes() to
-calculate rate_limit") introduced a prohibitive performance regression
-when taking a snapshot [0]. The reason turns out to be the flushing
-done by migration_transferred_bytes()
-
-Just use a _noflush version of the relevant function as a workaround
-until upstream fixes the issue. This is inspired by a not-applied
-upstream series [1], but doing the very minimum to avoid the
-regression.

+Subject: [PATCH] mirror: Don't call job_pause_point() under graph lock
+
+Calling job_pause_point() while holding the graph reader lock
+potentially results in a deadlock: bdrv_graph_wrlock() first drains
+everything, including the mirror job, which pauses it. The job is only
+unpaused at the end of the drain section, which is when the graph writer
+lock has been successfully taken. However, if the job happens to be
+paused at a pause point where it still holds the reader lock, the writer
+lock can't be taken as long as the job is still paused.
+
+Mark job_pause_point() as GRAPH_UNLOCKED and fix mirror accordingly.

-Subject: [PATCH] ui/clipboard: mark type as not available when there is no
- data
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.

-Subject: [PATCH] virtio-scsi: Attach event vq notifier with no_poll
-
-As of commit 38738f7dbbda90fbc161757b7f4be35b52205552 ("virtio-scsi:
-don't waste CPU polling the event virtqueue"), we only attach an io_read
-notifier for the virtio-scsi event virtqueue instead, and no polling
-notifiers. During operation, the event virtqueue is typically
-non-empty, but none of the buffers are intended to be used immediately.
-Instead, they only get used when certain events occur. Therefore, it
-makes no sense to continuously poll it when non-empty, because it is
-supposed to be and stay non-empty.
-
-We do this by using virtio_queue_aio_attach_host_notifier_no_poll()
-instead of virtio_queue_aio_attach_host_notifier() for the event
-virtqueue.
-
-Commit 766aa2de0f29b657148e04599320d771c36fd126 ("virtio-scsi: implement
-BlockDevOps->drained_begin()") however has virtio_scsi_drained_end() use
-virtio_queue_aio_attach_host_notifier() for all virtqueues, including
-the event virtqueue. This can lead to it being polled again, undoing
-the benefit of commit 38738f7dbbda90fbc161757b7f4be35b52205552.
-
-Fix it by using virtio_queue_aio_attach_host_notifier_no_poll() for the
-event virtqueue.

-Subject: [PATCH] virtio: Re-enable notifications after drain
-
-During drain, we do not care about virtqueue notifications, which is why
-we remove the handlers on it. When removing those handlers, whether vq
-notifications are enabled or not depends on whether we were in polling
-mode or not; if not, they are enabled (by default); if so, they have
-been disabled by the io_poll_start callback.
-
-Because we do not care about those notifications after removing the
-handlers, this is fine. However, we have to explicitly ensure they are
-enabled when re-attaching the handlers, so we will resume receiving
-notifications. We do this in virtio_queue_aio_attach_host_notifier*().
-If such a function is called while we are in a polling section,
-attaching the notifiers will then invoke the io_poll_start callback,
-re-disabling notifications.
-
-Because we will always miss virtqueue updates in the drained section, we
-also need to poll the virtqueue once after attaching the notifiers.

-Subject: [PATCH] virtio-blk: avoid using ioeventfd state in irqfd conditional
-
-Requests that complete in an IOThread use irqfd to notify the guest
-while requests that complete in the main loop thread use the traditional
-qdev irq code path. The reason for this conditional is that the irq code
-path requires the BQL:
-
- if (s->ioeventfd_started && !s->ioeventfd_disabled) {
- virtio_notify_irqfd(vdev, req->vq);
- } else {
- virtio_notify(vdev, req->vq);
- }
-
-There is a corner case where the conditional invokes the irq code path
-instead of the irqfd code path:
-
- static void virtio_blk_stop_ioeventfd(VirtIODevice *vdev)
- {
- ...
- /*
- * Set ->ioeventfd_started to false before draining so that host notifiers
- * are not detached/attached anymore.
- */
- s->ioeventfd_started = false;
-
- /* Wait for virtio_blk_dma_restart_bh() and in flight I/O to complete */
- blk_drain(s->conf.conf.blk);
-
-During blk_drain() the conditional produces the wrong result because
-ioeventfd_started is false.
-
-Use qemu_in_iothread() instead of checking the ioeventfd state.

-Subject: [PATCH] alloc-track: fix deadlock during drop
-
-by replacing the block node directly after changing the backing file
-instead of rescheduling it.
-
-With changes in QEMU 8.0, calling bdrv_get_info (and bdrv_unref)
-during drop can lead to a deadlock when using iothread (only triggered
-with multiple disks, except during debugging where it also triggered
-with one disk sometimes):
-1. job_unref_locked acquires the AioContext and calls job->driver->free
-2. track_drop gets scheduled
-3. bdrv_graph_wrlock is called and polls which leads to track_drop being
- called
-4. track_drop acquires the AioContext recursively
-5. bdrv_get_info is a wrapped coroutine (since 8.0) and thus polls for
- bdrv_co_get_info. This releases the AioContext, but only once! The
- documentation for the AIO_WAIT_WHILE macro states that the
- AioContext lock needs to be acquired exactly once, but there does
- not seem to be a way for track_drop to know if it acquired the lock
- recursively or not (without adding further hacks).
-6. Because the AioContext is still held by the main thread once, it can't
- be acquired before entering bdrv_co_get_info in co_schedule_bh_cb
- which happens in the iothread
-
-When doing the operation in change_backing_file, the AioContext has
-already been acquired by the caller, so the issue with the recursive
-lock goes away.
-
-The comment explaining why delaying the replace is necessary is
-> we need to schedule this for later however, since when this function
-> is called, the blockjob modifying us is probably not done yet and
-> has a blocker on 'bs'
-
-However, there is no check for blockers in bdrv_replace_node. It would
-need to be done by us, the caller, with check_to_replace_node.
-Furthermore, the mirror job also does its call to bdrv_replace_node
-while there is an active blocker (inserted by mirror itself) and they
-use a specialized version to check for blockers instead of
-check_to_replace_node there. Alloc-track could also do something
-similar to check for other blockers, but it should be fine to rely on
-Proxmox VE that no other operation with the blockdev is going on.
-
-Mirror also drains the target before replacing the node, but the
-target can have other users. In case of alloc-track the file child
-should not be accessible by anybody else and so there can't be an
-in-flight operation for the file child when alloc-track is drained.
-
-The rescheduling based on refcounting is a hack and it doesn't seem to
-be necessary anymore. It's not clear what the original issue from the
-comment was. Testing with older builds with track_drop done directly
-without rescheduling also didn't lead to any noticable issue for me.
-
-One issue it might have been is the one fixed by b1e1af394d
-("block/stream: Drain subtree around graph change"), where
-block-stream had a use-after-free if the base node changed at an
-inconvenient time (which alloc-track's auto-drop does).
-
-It's also not possible to just not auto-replace the alloc-track. Not
-replacing it at all leads to other operations like block resize
-hanging, and there is no good way to replace it manually via QMP
-(there is x-blockdev-change, but it is experimental and doesn't
-implement the required operation yet). Also, it's just cleaner in
-general to not leave unnecessary block nodes lying around.

+ update
+
+Doesn't seem necessary nowadays (maybe after commit "alloc-track: fix
+deadlock during drop" where the dropping is not rescheduled and delayed
+anymore or some upstream change). Should there really be some issue,
+instead of having a drop state, this could also be just based off the
+fact whether there is still a backing child.
+
+Dumping the cumulative (shared) permissions for the BDS with a debug
+print yields the same values after this patch and with QEMU 8.1,
+namely 3 and 5.

-Subject: [PATCH] migration: for snapshots, hold the BQL during setup callbacks
-
-In spirit, this is a partial revert of commit 9b09503752 ("migration:
-run setup callbacks out of big lock"), but only for the snapshot case.
-
-For snapshots, the bdrv_writev_vmstate() function is used during setup
-(in QIOChannelBlock backing the QEMUFile), but not holding the BQL
-while calling it could lead to an assertion failure. To understand
-how, first note the following:
-
-1. Generated coroutine wrappers for block layer functions spawn the
-coroutine and use AIO_WAIT_WHILE()/aio_poll() to wait for it.
-2. If the host OS switches threads at an inconvenient time, it can
-happen that a bottom half scheduled for the main thread's AioContext
-is executed as part of a vCPU thread's aio_poll().
-
-An example leading to the assertion failure is as follows:
-
-main thread:
-1. A snapshot-save QMP command gets issued.
-2. snapshot_save_job_bh() is scheduled.
-
-vCPU thread:
-3. aio_poll() for the main thread's AioContext is called (e.g. when
-the guest writes to a pflash device, as part of blk_pwrite which is a
-generated coroutine wrapper).
-4. snapshot_save_job_bh() is executed as part of aio_poll().
-3. qemu_savevm_state() is called.
-4. qemu_mutex_unlock_iothread() is called. Now
-qemu_get_current_aio_context() returns 0x0.
-5. bdrv_writev_vmstate() is executed during the usual savevm setup.
-But this function is a generated coroutine wrapper, so it uses
-AIO_WAIT_WHILE. There, the assertion
-assert(qemu_get_current_aio_context() == qemu_get_aio_context());
-will fail.

-Subject: [PATCH] savevm-async: don't hold BQL during setup
-
-See commit "migration: for snapshots, hold the BQL during setup
-callbacks" for why. This is separate, because a version of that one

To: pve-devel
Biggest change is that AioContext locking got removed, but no changes
required other than dropping the calls to acquire and release it. As a
consequence, the single parameter for the bdrv_graph_wrlock() call got
removed which also required adaptation.
QAPI docs became stricter requiring to document all members.
Other minor changes:
- Single parameter from migration_is_running() was dropped.
- qemu_mutex_(un)lock_iothread() got renamed to bql_(un)lock().

-Subject: [PATCH] migration/block-dirty-bitmap: fix loading bitmap when there
- is an iothread
-
-The bdrv_create_dirty_bitmap() function (which is also called by
-bdrv_dirty_bitmap_create_successor()) uses bdrv_getlength(bs). This is
-a wrapper around a coroutine, and thus uses bdrv_poll_co(). Polling
-tries to release the AioContext which will trigger an assert() if it
-hasn't been acquired before.
-
-The issue does not happen for migration, because there we are in a
-coroutine already, so the wrapper will just call bdrv_co_getlength()
-directly without polling.

-Subject: [PATCH] qemu_init: increase NOFILE soft limit on POSIX
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In many configurations, e.g. multiple vNICs with multiple queues or
-with many Ceph OSDs, the default soft limit of 1024 is not enough.
-QEMU is supposed to work fine with file descriptors >= 1024 and does
-not use select() on POSIX. Bump the soft limit to the allowed hard
-limit to avoid issues with the aforementioned configurations.
-
-Of course the limit could be raised from the outside, but the man page
-of systemd.exec states about 'LimitNOFILE=':
-
-> Don't use.
-> [...]
-> Typically applications should increase their soft limit to the hard
-> limit on their own, if they are OK with working with file
-> descriptors above 1023,
-
-If the soft limit is already the same as the hard limit, avoid the
-superfluous setrlimit call. This can avoid a warning with a strict
-seccomp filter blocking setrlimit if NOFILE was already raised before
-executing QEMU.

-Subject: [PATCH] mirror: Don't call job_pause_point() under graph lock
-
-Calling job_pause_point() while holding the graph reader lock
-potentially results in a deadlock: bdrv_graph_wrlock() first drains
-everything, including the mirror job, which pauses it. The job is only
-unpaused at the end of the drain section, which is when the graph writer
-lock has been successfully taken. However, if the job happens to be
-paused at a pause point where it still holds the reader lock, the writer
-lock can't be taken as long as the job is still paused.
-
-Mark job_pause_point() as GRAPH_UNLOCKED and fix mirror accordingly.

-From: Stefan Reiter <s.reiter@proxmox.com>
-Date: Tue, 2 Mar 2021 16:11:54 +0100
-Subject: [PATCH] block/io: accept NULL qiov in bdrv_pad_request
-
-Some operations, e.g. block-stream, perform reads while discarding the
-results (only copy-on-read matters). In this case they will pass NULL as
-the target QEMUIOVector, which will however trip bdrv_pad_request, since
-it wants to extend its passed vector.
-
-If there is no qiov, no operation can be done with it, but the bytes
-and offset still need to be updated, so the subsequent aligned read
-will actually be aligned and not run into an assertion failure.
-
-Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
-[FE: do update bytes and offset in any case]
