pve-qemu-kvm (9.0.0-2) bookworm; urgency=medium
|
||||
|
||||
* fix #5409: backup: fix copy-before-write timeout
|
||||
|
||||
* backup: improve error when copy-before-write fails for fleecing
|
||||
|
||||
* fix forwards and backwards migration with VirtIO-GPU display
|
||||
|
||||
* fix a regression in pflash device introduced in 8.2
|
||||
|
||||
* revert a commit for VirtIO PCI devices that turned out to cause more
|
||||
potential security issues than what it fixed
|
||||
|
||||
* move compatibility flags for a new VirtIO-net feature to the correct
|
||||
machine type. The feature was introduced in QEMU 8.2, but the
|
||||
compatibility flags got added to machine version 8.0 instead of 8.1. This
|
||||
breaks backwards migration with machine version 8.1 from a 8.2/9.0 binary
|
||||
to an 8.1 binary, in cases where the guest kernel enables the feature
|
||||
(e.g. Ubuntu 23.10).
|
||||
While that breaks migration with machine version 8.1 from an unpatched to
|
||||
a patched binary, Proxmox VE only ever had 8.2 on the test repository and
|
||||
9.0 not yet in any public repository.

are often a result of cancling the job due to running into an actual
|

issue.

|

Subject: [PATCH] block/block-copy: always align copied region to cluster size
|
||||
|
||||
Since commit 42ac214406e0 (block/block-copy: refactor task creation)
|
||||
block_copy_task_create calculates the area to be copied via
|
||||
bdrv_dirty_bitmap_next_dirty_area, but that can return an unaligned byte
|
||||
count if the image's last cluster end is not aligned to the bitmap's
|
||||
granularity.
|
||||
|
||||
Always ALIGN_UP the resulting bytes value to satisfy block_copy_do_copy,
|
||||
which requires the 'bytes' parameter to be aligned to cluster size.

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.

Host drivers do not necessarily set cdb_len in megasas io commands.
|
||||
With commits 6d1511cea0 ("scsi: Reject commands if the CDB length
|
||||
exceeds buf_len") and fe9d8927e2 ("scsi: Add buf_len parameter to
|
||||
scsi_req_new()"), this results in failures to boot Linux from affected
|
||||
SCSI drives because cdb_len is set to 0 by the host driver.
|
||||
Set the cdb length to its actual size to solve the problem.

Subject: [PATCH] ide: avoid potential deadlock when draining during trim
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The deadlock can happen as follows:
|
||||
1. ide_issue_trim is called, and increments the in_flight counter.
|
||||
2. ide_issue_trim_cb calls blk_aio_pdiscard.
|
||||
3. Somebody else starts draining (e.g. backup to insert the cbw node).
|
||||
4. ide_issue_trim_cb is called as the completion callback for
|
||||
blk_aio_pdiscard.
|
||||
5. ide_issue_trim_cb issues yet another blk_aio_pdiscard request.
|
||||
6. The request is added to the wait queue via blk_wait_while_drained,
|
||||
because draining has been started.
|
||||
7. Nobody ever decrements the in_flight counter and draining can't
|
||||
finish. This would be done by ide_trim_bh_cb, which is called after
|
||||
ide_issue_trim_cb has issued its last request, but
|
||||
ide_issue_trim_cb is not called anymore, because it's the
|
||||
completion callback of blk_aio_pdiscard, which waits on draining.
|
||||
|
||||
Quoting Hanna Czenczek:
|
||||
> The point of 7e5cdb345f was that we need any in-flight count to
|
||||
> accompany a set s->bus->dma->aiocb. While blk_aio_pdiscard() is
|
||||
> happening, we don’t necessarily need another count. But we do need
|
||||
> it while there is no blk_aio_pdiscard().
|
||||
> ide_issue_trim_cb() returns in two cases (and, recursively through
|
||||
> its callers, leaves s->bus->dma->aiocb set):
|
||||
> 1. After calling blk_aio_pdiscard(), which will keep an in-flight
|
||||
> count,
|
||||
> 2. After calling replay_bh_schedule_event() (i.e.
|
||||
> qemu_bh_schedule()), which does not keep an in-flight count.
|
||||
|
||||
Thus, even after moving the blk_inc_in_flight to above the
|
||||
replay_bh_schedule_event call, the invariant "ide_issue_trim_cb
|
||||
returns with an accompanying in-flight count" is still satisfied.
|
||||
|
||||
However, the issue 7e5cdb345f fixed for canceling resurfaces, because
|
||||
ide_cancel_dma_sync assumes that it just needs to drain once. But now
|
||||
the in_flight count is not consistently > 0 during the trim operation.
|
||||
So, change it to drain until !s->bus->dma->aiocb, which means that the
|
||||
operation finished (s->bus->dma->aiocb is cleared by ide_set_inactive
|
||||
via the ide_dma_cb when the end of the transfer is reached).

|

|
||||
Store calculated setup_len in a local variable, verify it, and only
|
||||
write it to the struct (USBDevice->setup_len) in case it passed the
|
||||
sanity checks.
|
||||
|
||||
This prevents other code (do_token_{in,out} functions specifically)
|
||||
from working with invalid USBDevice->setup_len values and overrunning
|

the USBDevice->setup_buf[] buffer.

As reported in the community forum [0] and reproduced locally this

Subject: [PATCH] block/copy-before-write: use uint64_t for timeout in
|
||||
nanoseconds
|
||||
|
||||
rather than the uint32_t for which the maximum is slightly more than 4
|
||||
seconds and larger values would overflow. The QAPI interface allows
|
||||
specifying the number of seconds, so only values 0 to 4 are safe right
|
||||
now, other values lead to a much lower timeout than a user expects.
|
||||
|
||||
The block_copy() call where this is used already takes a uint64_t for
|
||||
the timeout, so no change required there.
|
||||

||||

Commit dfcf74fa ("virtio-gpu: fix scanout migration post-load") broke
|
||||
forward/backward version migration. Versioning of nested VMSD structures
|
||||
is not straightforward, as the wire format doesn't have nested
|
||||
structures versions. Introduce x-scanout-vmstate-version and a field
|
||||
test to save/load appropriately according to the machine version.

Move the pflash_blk_write_start() call. We need the offset of the
|
||||
first data write, not the offset for the setup (number-of-bytes)
|
||||
write. Without this fix u-boot can do block writes to the first
|
||||
flash block only.
|
||||
|
||||
While being at it drop a leftover FIXME.

Subject: [PATCH] target/i386: fix operand size for DATA16 REX.W POPCNT
|
||||
|
||||
According to the manual, 32-bit vs 64-bit is governed by REX.W
|
||||
and REX ignores the 0x66 prefix. This can be confirmed with this
|
||||
program:
|
||||
|
||||
#include <stdio.h>
|
||||
int main()
|
||||
{
|
||||
int x = 0x12340000;
|
||||
int y;
|
||||
asm("popcntl %1, %0" : "=r" (y) : "r" (x)); printf("%x\n", y);
|
||||
asm("mov $-1, %0; .byte 0x66; popcntl %1, %0" : "+r" (y) : "r" (x)); printf("%x\n", y);
|
||||
asm("mov $-1, %0; .byte 0x66; popcntq %q1, %q0" : "+r" (y) : "r" (x)); printf("%x\n", y);
|
||||
}
|
||||
|
||||
which prints 5/ffff0000/5 on real hardware and 5/ffff0000/ffff0000
|
||||
on QEMU.

Subject: [PATCH] Revert "virtio-pci: fix use of a released vector"
|
||||
|
||||
This reverts commit 2ce6cff94df2650c460f809e5ad263f1d22507c0.
|
||||
|
||||
The fix causes some issues:
|
||||
https://gitlab.com/qemu-project/qemu/-/issues/2321
|
||||
https://gitlab.com/qemu-project/qemu/-/issues/2334
|
||||
|
||||
The CVE fixed by commit 2ce6cff94d ("virtio-pci: fix use of a released
|
||||
vector") is CVE-2024-4693 [0] and allows a malicious guest that
|
||||
controls the boot process in the guest to crash its QEMU process.
|
||||
|
||||
The issues sound worse than the CVE, so revert until there is a proper
|
||||
fix.
|
||||
|
||||
[0]: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-4693

Subject: [PATCH] hw/core/machine: move compatibility flags for VirtIO-net USO
|
||||
to machine 8.1
|
||||
|
||||
Migration from an 8.2 or 9.0 binary to an 8.1 binary with machine
|
||||
version 8.1 can fail with:
|
||||
|
||||
> kvm: Features 0x1c0010130afffa7 unsupported. Allowed features: 0x10179bfffe7
|
||||
> kvm: Failed to load virtio-net:virtio
|
||||
> kvm: error while loading state for instance 0x0 of device '0000:00:12.0/virtio-net'
|
||||
> kvm: load of migration failed: Operation not permitted
|
||||
|
||||
The series
|
||||
|
||||
53da8b5a99 virtio-net: Add support for USO features
|
||||
9da1684954 virtio-net: Add USO flags to vhost support.
|
||||
f03e0cf63b tap: Add check for USO features
|
||||
2ab0ec3121 tap: Add USO support to tap device.
|
||||
|
||||
only landed in QEMU 8.2, so the compatibility flags should be part of
|
||||
machine version 8.1.
|
||||
|
||||
Moving the flags unfortunately breaks forward migration with machine
|
||||
version 8.1 from a binary without this patch to a binary with this
|
||||
patch when the feature is enabled by the guest.

||||

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] add optional buffer size to QEMUFile
|

So we can use a 4M buffer for savevm-async which should
|

increase performance storing the state onto ceph.

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.

|

|

Notes about partial restoring: skipping a certain drive is done via a

map line 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.

Subject: [PATCH] PVE-Backup: avoid coroutines to fix AIO freeze, cleanups
|
||||
|
||||
We observed various AIO pool loop freezes, so we decided to avoid
|
||||
coroutines and restrict ourselfes using similar code as upstream
|
||||
(see blockdev.c: do_backup_common).
|
||||
|
||||
* avoid coroutine for job related code (causes hangs with iothreads)
|
||||
- We then acquire/release all mutexes outside coroutines now, so we can now
|
||||
correctly use a normal mutex.
|
||||
|
||||
* split pvebackup_co_dump_cb into:
|
||||
- pvebackup_co_dump_pbs_cb and
|
||||
- pvebackup_co_dump_pbs_cb
|
||||
|
||||
* new helper functions
|
||||
- pvebackup_propagate_error
|
||||
- pvebackup_error_or_canceled
|
||||
- pvebackup_add_transfered_bytes
|
||||
|
||||
* avoid cancel flag (not needed)
|
||||
|
||||
* simplify backup_cancel logic
|
||||
|
||||
There is progress on upstream to support running qmp commands inside
|
||||
coroutines, see:
|
||||
https://lists.gnu.org/archive/html/qemu-devel/2020-02/msg04852.html
|
||||
|
||||
We should consider using that when it is available in upstream qemu.

Subject: [PATCH] PVE: fall back to open-iscsi initiatorname
|
||||
|
||||
When no explicit option is given, try reading the initiator name from
|
||||
/etc/iscsi/initiatorname.iscsi and only use the generic fallback, i.e.
|
||||
iqn.2008-11.org.linux-kvmXXX, as a third alternative.
|
||||
|
||||
This avoids the need to add an explicit option for vma and to explicitly set it
|
||||
for each call to qemu that deals with iSCSI disks, while still allowing to set
|
||||
the option if a different name is needed.
|
||||
|
||||
According to RFC 3720, an initiator name is at most 223 bytes long, so the
|
||||
4 KiB buffer is big enough, even if many whitespaces are used.

Subject: [PATCH] PVE-Backup: Add dirty-bitmap tracking for incremental backups
|
||||
|
||||
Uses QEMU's existing MIRROR_SYNC_MODE_BITMAP and a dirty-bitmap on top
|
||||
of all backed-up drives. This will only execute the data-write callback
|
||||
for any changed chunks, the PBS rust code will reuse chunks from the
|
||||
previous index for everything it doesn't receive if reuse_index is true.
|
||||
|
||||
On error or cancellation, remove all dirty bitmaps to ensure
|
||||
consistency.
|
||||
|
||||
Add PBS/incremental specific information to query backup info QMP and
|
||||
HMP commands.
|
||||
|
||||
Only supported for PBS backups.

Subject: [PATCH] block: add alloc-track driver
|
||||
|
||||
Add a new filter node 'alloc-track', which seperates reads and writes to
|
||||
different children, thus allowing to put a backing image behind any
|
||||
blockdev (regardless of driver support). Since we can't detect any
|
||||
pre-allocated blocks, we can only track new writes, hence the write
|
||||
target ('file') for this node must always be empty.
|
||||
|
||||
Intended use case is for live restoring, i.e. add a backup image as a
|
||||
block device into a VM, then put an alloc-track on the restore target
|
||||
and set the backup as backing. With this, one can use a regular
|
||||
'block-stream' to restore the image, while the VM can already run in the
|
||||
background. Copy-on-read will help make progress as the VM reads as
|
||||
well.
|
||||
|
||||
This only worked if the target supports backing images, so up until now
|
||||
only for qcow2, with alloc-track any driver for the target can be used.
|
||||
|
||||
Replacing the node cannot be done in the
|
||||
track_co_change_backing_file() callback, because replacing a node
|
||||
cannot happen in a coroutine and requires the block graph lock
|
||||
exclusively. Could either become a special option for the stream job,
|
||||
or maybe the upcoming blockdev-replace QMP command can be used in the
|
||||
future.

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] alloc-track: error out when auto-remove is not set
|
||||
|
||||
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.
|
||||
|
||||
qemu-server will always set it, make sure to have other users notice
|
||||
the change (should they even exist). The option can be fully dropped
|
||||
in the future while adding a version guard in qemu-server.

Subject: [PATCH] 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). 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] block/copy-before-write: fix permission
|
||||
|
||||
In case when source node does not have any parents, the condition still
|
||||
works as required: backup job do create the parent by
|
||||
|
||||
block_job_create -> block_job_add_bdrv -> bdrv_root_attach_child
|
||||
|
||||
Still, in this case checking @perm variable doesn't work, as backup job
|
||||
creates the root blk with empty permissions (as it rely on CBW filter
|
||||
to require correct permissions and don't want to create extra
|
||||
conflicts).
|
||||
|
||||
So, we should not check @perm.
|
||||
|
||||
The hack may be dropped entirely when transactional insertion of
|
||||
filter (when we don't try to recalculate permissions in intermediate
|
||||
state, when filter does conflict with original parent of the source
|
||||
node) merged (old big series
|
||||
"[PATCH v5 00/45] Transactional block-graph modifying API"[1] and it's
|
||||
current in-flight part is "[PATCH v8 0/7] blockdev-replace"[2])

Subject: [PATCH] PVE: handle PBS write callback with big blocks correctly
|
||||
|
||||
Under certain conditions QEMU will push more than the given blocksize
|
||||
into the callback at once. Handle it like VMA does, by iterating the
|
||||
data until all is written.
|
||||
|
||||
The block size is stored per backup device to be used in the callback.
|
||||
This avoids relying on PROXMOX_BACKUP_DEFAULT_CHUNK_SIZE, in case it is
|
||||
made configurable in the future.

Subject: [PATCH] block/copy-before-write: create block_copy bitmap in filter
|
||||
node
|
||||
|
||||
Currently block_copy creates copy_bitmap in source node. But that is in
|
||||
bad relation with .independent_close=true of copy-before-write filter:
|
||||
source node may be detached and removed before .bdrv_close() handler
|
||||
called, which should call block_copy_state_free(), which in turn should
|
||||
remove copy_bitmap.
|
||||
|
||||
That's all not ideal: it would be better if internal bitmap of
|
||||
block-copy object is not attached to any node. But that is not possible
|
||||
now.
|
||||
|
||||
The simplest solution is just create copy_bitmap in filter node, where
|
||||
anyway two other bitmaps are created.

Subject: [PATCH] PVE: add zero block handling to PBS dump callback
|
||||
|
||||
Both the PBS and VMA dump callbacks assume that a NULL pointer can be
|
||||
passed as *pbuf, but that never happens, as backup-dump.c calls this
|
||||
function with contents of an iovec.
|
||||
|
||||
So first, remove that assumption and add an 'assert' to verify.
|
||||
|
||||
Secondly, while the vma-writer already does the buffer_is_zero check
|
||||
internally, for PBS we relied on that non-existant behaviour for zero
|
||||
chunks, so do the buffer_is_zero check manually and pass NULL to the
|
||||
rust lib in case it is true.

Subject: [PATCH] qapi: blockdev-backup: add discard-source parameter
|
||||
|
||||
Add a parameter that enables discard-after-copy. That is mostly useful
|
||||
in "push backup with fleecing" scheme, when source is snapshot-access
|
||||
format driver node, based on copy-before-write filter snapshot-access
|
||||
API:
|
||||
|
||||
[guest] [snapshot-access] ~~ blockdev-backup ~~> [backup target]
|
||||
| |
|
||||
| root | file
|
||||
v v
|
||||
[copy-before-write]
|
||||
| |
|
||||
| file | target
|
||||
v v
|
||||
[active disk] [temp.img]
|
||||
|
||||
In this case discard-after-copy does two things:
|
||||
|
||||
- discard data in temp.img to save disk space
|
||||
- avoid further copy-before-write operation in discarded area
|
||||
|
||||
Note that we have to declare WRITE permission on source in
|
||||
copy-before-write filter, for discard to work. Still we can't take it
|
||||
unconditionally, as it will break normal backup from RO source. So, we
|
||||
have to add a parameter and pass it thorough bdrv_open flags.

Useful to make discard-source work in the context of backup fleecing
|
||||
when the fleecing image has a larger granularity than the backup
|
||||
target.
|
||||
|
||||
Copy-before-write operations will use at least this granularity and in
|
||||
particular, discard requests to the source node will too. If the
|
||||
granularity is too small, they will just be aligned down in
|
||||
cbw_co_pdiscard_snapshot() and thus effectively ignored.
|
||||
|
||||
The QAPI uses uint32 so the value will be non-negative, but still fit
|
||||
into a uint64_t.

Subject: [PATCH] PVE backup: add fleecing option
|
||||
|
||||
When a fleecing option is given, it is expected that each device has
|
||||
a corresponding "-fleecing" block device already attached, except for
|
||||
EFI disk and TPM state, where fleecing is never used.
|
||||
|
||||
The following graph was adapted from [0] which also contains more
|
||||
details about fleecing.
|
||||
|
||||
[guest]
|
||||
|
|
||||
| root
|
||||
v file
|
||||
[copy-before-write]<------[snapshot-access]
|
||||
| |
|
||||
| file | target
|
||||
v v
|
||||
[source] [fleecing]
|
||||
|
||||
For fleecing, a copy-before-write filter is inserted on top of the
|
||||
source node, as well as a snapshot-access node pointing to the filter
|
||||
node which allows to read the consistent state of the image at the
|
||||
time it was inserted. New guest writes are passed through the
|
||||
copy-before-write filter which will first copy over old data to the
|
||||
fleecing image in case that old data is still needed by the
|
||||
snapshot-access node.
|
||||
|
||||
The backup process will sequentially read from the snapshot access,
|
||||
which has a bitmap and knows whether to read from the original image
|
||||
or the fleecing image to get the "snapshot" state, i.e. data from the
|
||||
source image at the time when the copy-before-write filter was
|
||||
inserted. After reading, the copied sections are discarded from the
|
||||
fleecing image to reduce space usage.
|
||||
|
||||
All of this can be restricted by an initial dirty bitmap to parts of
|
||||
the source image that are required for an incremental backup.
|
||||
|
||||
For discard to work, it is necessary that the fleecing image does not
|
||||
have a larger cluster size than the backup job granularity. Since
|
||||
querying that size does not always work, e.g. for RBD with krbd, the
|
||||
cluster size will not be reported, a minimum of 4 MiB is used. A job
|
||||
with PBS target already has at least this granularity, so it's just
|
||||
relevant for other targets. I.e. edge cases where this minimum is not
|
||||
enough should be very rare in practice. If ever necessary in the
|
||||
future, can still add a passed-in value for the backup QMP command to
|
||||
override.
|
||||
|
||||
Additionally, the cbw-timeout and on-cbw-error=break-snapshot options
|
||||
are set when installing the copy-before-write filter and
|
||||
snapshot-access. When an error or timeout occurs, the problematic (and
|
||||
each further) snapshot operation will fail and thus cancel the backup
|
||||
instead of breaking the guest write.
|
||||
|
||||
Note that job_id cannot be inferred from the snapshot-access bs because
|
||||
it has no parent, so just pass the one from the original bs.

Subject: [PATCH] PVE-Backup: Use a transaction to synchronize job states
|
||||
|
||||
By using a JobTxn, we can sync dirty bitmaps only when *all* jobs were
|
||||
successful - meaning we don't need to remove them when the backup fails,
|
||||
since QEMU's BITMAP_SYNC_MODE_ON_SUCCESS will now handle that for us.
|
||||
|
||||
To keep the rate-limiting and IO impact from before, we use a sequential
|
||||
transaction, so drives will still be backed up one after the other.

||||

Subject: [PATCH] PVE backup: improve error when copy-before-write fails for
|
||||
fleecing
|
||||
|
||||
With fleecing, failure for copy-before-write does not fail the guest
|
||||
write, but only sets the snapshot error that is associated to the
|
||||
copy-before-write filter, making further requests to the snapshot
|
||||
access fail with EACCES, which then also fails the job. But that error
|
||||
code is not the root cause of why the backup failed, so bubble up the
|
||||
original snapshot error instead.

Subject: [PATCH] PVE-Backup: Use more coroutines and don't block on finishing
|
||||
|
||||
proxmox_backup_co_finish is already async, but previously we would wait
|
||||
for the coroutine using block_on_coroutine_fn(). Avoid this by
|
||||
scheduling pvebackup_co_complete_stream (and thus pvebackup_co_cleanup)
|
||||
as a real coroutine when calling from pvebackup_complete_cb. This is ok,
|
||||
since complete_stream uses the backup_mutex internally to synchronize,
|
||||
and other streams can happily continue writing in the meantime anyway.
|
||||
|
||||
To accomodate, backup_mutex is converted to a CoMutex. This means
|
||||
converting every user to a coroutine. This is not just useful here, but
|
||||
will come in handy once this series[0] is merged, and QMP calls can be
|
||||
yield-able coroutines too. Then we can also finally get rid of
|
||||
block_on_coroutine_fn.
|
||||
|
||||
Cases of aio_context_acquire/release from within what is now a coroutine
|
||||
are changed to aio_co_reschedule_self, which works since a running
|
||||
coroutine always holds the aio lock for the context it is running in.
|
||||
|
||||
job_cancel_sync is called from a BH since it can't be run from a
|
||||
coroutine (uses AIO_WAIT_WHILE internally).
|
||||
|
||||
Same thing for create_backup_jobs, which is converted to a BH too.
|
||||
|
||||
To communicate the finishing state, a new property is introduced to
|
||||
query-backup: 'finishing'. A new state is explicitly not used, since
|
||||
that would break compatibility with older qemu-server versions.
