-Subject: [PATCH] monitor/qmp: fix race with clients disconnecting early
-
-The following sequence can produce a race condition that results in
-responses meant for different clients being sent to the wrong one:
-
-(QMP, no OOB)
-1) client A connects
-2) client A sends 'qmp_capabilities'
-3) 'qmp_dispatch' runs in coroutine, schedules out to
-   'do_qmp_dispatch_bh' and yields
-4) client A disconnects (i.e. aborts, crashes, etc...)
-5) client B connects
-6) 'do_qmp_dispatch_bh' runs 'qmp_capabilities' and wakes calling coroutine
-7) capabilities are now set and 'mon->commands' is set to '&qmp_commands'
-8) 'qmp_dispatch' returns to 'monitor_qmp_dispatch'
-9) success message is sent to client B *without it ever having sent
-   'qmp_capabilities' itself*
-9a) even if client B ignores it, it will now presumably send it's own
-   greeting, which will error because caps are already set
-
-The fix proposed here uses an atomic, sequential connection number
-stored in the MonitorQMP struct, which is incremented everytime a new
-client connects. Since it is not changed on CHR_EVENT_CLOSED, the
-behaviour of allowing a client to disconnect only one side of the
-connection is retained.
-
-The connection_nr needs to be exposed outside of the monitor subsystem,
-since qmp_dispatch lives in qapi code. It needs to be checked twice,
-once for actually running the command in the BH (fixes 7), and once for
-sending back a response (fixes 9).
-
-This satisfies my local reproducer - using multiple clients constantly
-looping to open a connection, send the greeting, then exiting no longer
-crashes other, normally behaving clients with unrelated responses.

-Subject: [PATCH] block/io_uring: revert "Use io_uring_register_ring_fd() to
- skip fd operations"
-
-Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1193
-
-The commit "Use io_uring_register_ring_fd() to skip fd operations" broke
-when booting a guest with iothread and io_uring. That is because the
-io_uring_register_ring_fd() call is made from the main thread instead of
-IOThread where io_uring_submit() is called. It can not be guaranteed
-to register the ring fd in the correct thread or unregister the same ring
-fd if the IOThread is disabled. This optimization is not critical so we
-will revert previous commit.
-
-This reverts commit e2848bc574fe2715c694bf8fe9a1ba7f78a1125a
-and 77e3f038af1764983087e3551a0fde9951952c4d.

-For backward compatibility, g_date_time_get_microsecond should be used

-If finalize chardev-msmouse or chardev-wctable is called immediately after

+Subject: [PATCH] virtiofsd: extract lo_do_open() from lo_open()
+
+Both lo_open() and lo_create() have similar code to open a file. Extract
+a common lo_do_open() function from lo_open() that will be used by
+lo_create() in a later commit.
+
+Since lo_do_open() does not otherwise need fuse_req_t req, convert
+lo_add_fd_mapping() to use struct lo_data *lo instead.

-Subject: [PATCH] init: daemonize: defuse PID file resolve error
-
-When proxmox-file-restore invokes QEMU, the PID file is a (temporary)
-file that's already unlinked, so resolving the absolute path here
-failed.
-
-It should not be a critical error when the PID file unlink handler
-can't be registered, because the path can't be resolved for whatever
-reason. If the file is already gone from QEMU's perspective (i.e.
-errno is ENOENT), silently ignore the error. Otherwise, print a
-warning.

+
+lo_do_lookup() finds an existing inode or allocates a new one. It
+increments nlookup so that the inode stays alive until the client
+releases it.
+
+Existing callers don't need the struct lo_inode so the function doesn't
+return it. Extend the function to optionally return the inode. The next
+commit will need it.

+Subject: [PATCH] virtiofsd: prevent opening of special files (CVE-2020-35517)
+
+A well-behaved FUSE client does not attempt to open special files with
+FUSE_OPEN because they are handled on the client side (e.g. device nodes
+are handled by client-side device drivers).
+
+The check to prevent virtiofsd from opening special files is missing in
+a few cases, most notably FUSE_OPEN. A malicious client can cause
+virtiofsd to open a device node, potentially allowing the guest to
+escape. This can be exploited by a modified guest device driver. It is
+not exploitable from guest userspace since the guest kernel will handle
+special files inside the guest instead of sending FUSE requests.
+
+This patch fixes this issue by introducing the lo_inode_open() function
+to check the file type before opening it. This is a short-term solution
+because it does not prevent a compromised virtiofsd process from opening
+device nodes on the host.
+
+Restructure lo_create() to try O_CREAT | O_EXCL first. Note that O_CREAT
+| O_EXCL does not follow symlinks, so O_NOFOLLOW masking is not
+necessary here. If the file exists and the user did not specify O_EXCL,
+open it via lo_do_open().

+Subject: [PATCH] monitor/qmp: fix race on CHR_EVENT_CLOSED without OOB
+
+The QMP dispatcher coroutine holds the qmp_queue_lock over a yield
+point, where it expects to be rescheduled from the main context. If a
+CHR_EVENT_CLOSED event is received just then, it can race and block the
+main thread on the mutex in monitor_qmp_cleanup_queue_and_resume.
+
+Calculate need_resume immediately after we pop a request from the queue,
+so that we can release the mutex before yielding.

+Subject: [PATCH] block: Fix deadlock in bdrv_co_yield_to_drain()
+
+If bdrv_co_yield_to_drain() is called for draining a block node that
+runs in a different AioContext, it keeps that AioContext locked while it
+yields and schedules a BH in the AioContext to do the actual drain.
+
+As long as executing the BH is the very next thing that the event loop
+of the node's AioContext does, this actually happens to work, but when
+it tries to execute something else that wants to take the AioContext
+lock, it will deadlock. (In the bug report, this other thing is a
+virtio-scsi device running virtio_scsi_data_plane_handle_cmd().)
+
+Instead, always drop the AioContext lock across the yield and reacquire
+it only when the coroutine is reentered. The BH needs to unconditionally
+take the lock for itself now.
+
+This fixes the 'block_resize' QMP command on a block node that runs in
+an iothread.

-Subject: [PATCH] PVE: add IOChannel implementation for savevm-async
-
-based on migration/channel-block.c and the implementation that was
-present in migration/savevm-async.c before QEMU 7.1.
-
-Passes along read/write requests to the given BlockBackend, while
-ensuring that a read request going beyond the end results in a
-graceful short read.
-
-Additionally, allows tracking the current position from the outside
-(intended to be used for progress tracking).

-Subject: [PATCH] block/backup: move bcs bitmap initialization to job creation
-
-For backing up the state of multiple disks from the same time, a job
-for each disk has to be created. It's convenient if the jobs don't
-have to be started at the same time and if operation of the VM can be
-resumed after job creation. This would lead to a window between job
-creation and running the job, where writes can happen. But no writes
-should happen between setting up the copy-before-write filter and
-setting up the block copy state bitmap, because then new writes would
-just pass through.
-
-Commit 06e0a9c16405c0a4c1eca33cf286cc04c42066a2 moved initalization of
-the bitmap to setting up the copy-before-write filter when sync_mode
-is not MIRROR_SYNC_MODE_BITMAP. Ensure that the bitmap is initialized
-upon job creation for the remaining case too, by moving the
-backup_init_bcs_bitmap call to backup_job_create.

+
+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.
+
+Simply check for NULL and do nothing, there's no reason to pad the
+target if it will be discarded anyway.

-Subject: [PATCH] vma: allow partial restore
-
-Introduce a new map line for skipping a certain drive, of the form
-skip=drive-scsi0
-
-Since in PVE, most archives are compressed and piped to vma for
-restore, it's not easily possible to skip reads.
-
-For the reader, a new skip flag for VmaRestoreState is added and the
-target is allowed to be NULL if skip is specified when registering. If
-the skip flag is set, no writes will be made as well as no check for
-duplicate clusters. Therefore, the flag is not set for verify.

-Subject: [PATCH] Revert "block/rbd: implement bdrv_co_block_status"
-
-During backup, bdrv_co_block_status is called for each block copy
-chunk. When RBD is used, the current implementation with
-rbd_diff_iterate2() using whole_object=true takes about linearly more
-time, depending on the image size. Since there are linearly more
-chunks, the slowdown is quadratic, becoming unacceptable for large
-images (starting somewhere between 500-1000 GiB in my testing).
-
-This reverts commit 0347a8fd4c3faaedf119be04c197804be40a384b as a
-stop-gap measure, until it's clear how to make the implemenation
-more efficient.

-Subject: [PATCH] PVE-Backup: create jobs: correctly cancel in error scenario
-
-The first call to job_cancel_sync() will cancel and free all jobs in
-the transaction, so ensure that it's called only once and get rid of
-the job_unref() that would operate on freed memory.
-
-It's also necessary to NULL backup_state.pbs in the error scenario,
-because a subsequent backup_cancel QMP call (as happens in PVE when
-the backup QMP command fails) would try to call proxmox_backup_abort()
-and run into a segfault.

-
-Ensures that qmp_backup_cancel doesn't pick a job that's already been
-freed. With unlucky timings it seems possible that:
-1. job_exit -> job_completed -> job_finalize_single starts
-2. pvebackup_co_complete_stream gets spawned in completion callback
-3. job finalize_single finishes -> job's refcount hits zero -> job is
-   freed
-4. qmp_backup_cancel comes in and locks backup_state.backup_mutex
-   before pvebackup_co_complete_stream can remove the job from the
-   di_list
-5. qmp_backup_cancel will pick a job that's already been freed

-Subject: [PATCH] PVE-Backup: avoid segfault issues upon backup-cancel
-
-When canceling a backup in PVE via a signal it's easy to run into a
-situation where the job is already failing when the backup_cancel QMP
-command comes in. With a bit of unlucky timing on top, it can happen
-that job_exit() runs between schedulung of job_cancel_bh() and
-execution of job_cancel_bh(). But job_cancel_sync() does not expect
-that the job is already finalized (in fact, the job might've been
-freed already, but even if it isn't, job_cancel_sync() would try to
-deref job->txn which would be NULL at that point).
-
-It is not possible to simply use the job_cancel() (which is advertised
-as being async but isn't in all cases) in qmp_backup_cancel() for the
-same reason job_cancel_sync() cannot be used. Namely, because it can
-invoke job_finish_sync() (which uses AIO_WAIT_WHILE and thus hangs if
-called from a coroutine). This happens when there's multiple jobs in
-the transaction and job->deferred_to_main_loop is true (is set before
-scheduling job_exit()) or if the job was not started yet.
-
-Fix the issue by selecting the job to cancel in job_cancel_bh() itself
-using the first job that's not completed yet. This is not necessarily
-the first job in the list, because pvebackup_co_complete_stream()
-might not yet have removed a completed job when job_cancel_bh() runs.
-
-An alternative would be to continue using only the first job and
-checking against JOB_STATUS_CONCLUDED or JOB_STATUS_NULL to decide if
-it's still necessary and possible to cancel, but the approach with
-using the first non-completed job seemed more robust.

-Subject: [PATCH] vma: create: support 64KiB-unaligned input images
-
-which fixes backing up templates with such disks in PVE, for example
-efitype=4m EFI disks on a file-based storage (size = 540672).
-
-If there is not enough left to read, blk_co_preadv will return -EIO,
-so limit the size in the last iteration.
-
-For writing, an unaligned end is already handled correctly.
-
-The call to memset is not strictly necessary, because writing also
-checks that it doesn't write data beyond the end of the image. But
-there are two reasons to do it:
-1. It's cleaner that way.
-2. It allows detecting when the final piece is all zeroes, which might
-   not happen if the buffer still contains data from the previous
-   iteration.

-
-While the bdrv_co_preadv() calls are expected to return 0 on success,
-qemu_iovec_memset() will return the number of bytes set (will be
-local_bytes, because the slice with that size was just initialized).
-
-Don't break out of the loop after the branch with qemu_iovec_memset(),
-because there might still be work to do. Additionally, ret is an int,
-which on 64-bit platforms is too small to hold the size_t returned by
-qemu_iovec_memset().
-
-The branch seems to be difficult to reach in practice, because the
-whole point of alloc-track is to be used with a backing device.

-Subject: [PATCH] PVE Backup: allow passing max-workers performance setting
-
-For query-proxmox-support, add an indication that it's possible to use
-the setting.
-
-For now, the other two BackupPerf settings are not exposed:
-
-* use-copy-range: would need to be implemented by the backup-dump
-block driver first, and in fact, the default for backup was changed,
-because it wasn't as fast for backup in QEMU, see commit
-6a30f663d4c0b3c45a544d541e0c4e214b2473a1.
-
-* max-chunk: enforced to be at least the backup cluster size, which is
-4 MiB for PBS and otherwise maximum of source and target cluster size.
-And block-copy has a maximum buffer size of 1 MiB, so setting a larger
-max-chunk doesn't even have an effect. To make the setting sensibly
-usable the check would need to be removed and optionally the
-block-copy max buffer size would need to be bumped. I tried doing just
-that, and tested different source/target combinations with different
-max-chunk settings, but there were no noticable improvements over the
-default "unlimited" (resulting in 1 MiB for block-copy).
