[PATCH v2 00/21] blksnap - block devices snapshots module

[Sergei Shtepa]

Hi Jens. Hi Jonathan. Hi all.

I am happy to offer a modified version of the Block Devices Snapshots
Module. It allows to create non-persistent snapshots of any block devices.
The main purpose of such snapshots is to provide backups of block devices.
See more in Documentation/block/blksnap.rst.

The Block Device Filtering Mechanism is added to the block layer. This
allows to attach and detach block device filters to the block layer.
Filters allow to extend the functionality of the block layer.
See more in Documentation/block/blkfilter.rst.

A tool, a library for working with blksnap and tests can be found at
www.github.com/veeam/blksnap.

The first version was suggested at 13 June 2022. Many thanks to
Christoph Hellwig and Randy Dunlap for the review of that version.

Changes:
- Forgotten "static" declarations have been added.
- The text of the comments has been corrected.
- It is possible to connect only one filter, since there are no others in
  upstream.
- Do not have additional locks for attach/detach filter.
- blksnap.h moved to include/uapi/.
- #pragma once and commented code removed.
- uuid_t removed from user API.
- Removed default values for module parameters from the configuration file.
- The debugging code for tracking memory leaks has been removed.
- Simplified Makefile.
- Optimized work with large memory buffers, CBT tables are now in virtual
  memory.
- The allocation code of minor numbers has been optimized.
- The implementation of the snapshot image block device has been
  simplified, now it is a bio-based block device.
- Removed initialization of global variables with null values.
- Only one bio is used to copy one chunk.
- Checked on ppc64le.

The v1 version was suggested at 2 November 2022. Many thanks to Fabio
Fantoni for his for his participation in the "blksnap" project on github
and Jonathan Corbet for his article https://lwn.net/Articles/914031/.
Thanks to the impartial kernel test robot.

Changes:
- Added documentation for Block Device Filtering Mechanism.
- Added documentation for Block Devices Snapshots Module (blksnap).
- The MAINTAINERS file has been updated.
- Optimized queue code for snapshot images.
- Fixed comments, log messages and code for better readability.

+================================
+Block Device Filtering Mechanism
+================================
+
+The block device filtering mechanism is an API that allows to attach block
+device filters. Block device filters allow perform additional processing
+for I/O units.
+
+Introduction
+============
+
+The idea of handling I/O units on block devices is not new. Back in the
+2.6 kernel, there was an undocumented possibility of handling I/O units
+by substituting the make_request_fn() function, which belonged to the
+request_queue structure. But no kernel module used this feature, and it
+was eliminated in the 5.10 kernel.
+
+The block device filtering mechanism returns the ability to handle I/O units.
+It is possible to safely attach filter to a block device "on the fly" without
+changing the structure of block devices.
+
+It supports attaching one filter to one block device, because there is only
+one filter implementation in the kernel.
+See Documentation/block/blksnap.rst.
+
+Design
+======
+
+The block device filtering mechanism provides functions for attaching and
+detaching the filter. The filter is a structure with a reference counter
+and callback functions.
+
+The submit_bio_cb() callback function is called for each I/O unit for a block
+device, providing I/O unit filtering. Depending on the result of filtering
+the I/O unit, it can either be passed for subsequent processing by the block
+layer, or skipped.
+
+The reference counter allows to control the filter lifetime. When the reference
+count is reduced to zero, the release_cb() callback function is called to
+release the filter. This allows the filter to be released when the block
+device is disconnected.

+Block Devices Snapshots Module (blksnap)
+========================================
+
+Introduction
+============
+
+At first glance, there is no novelty in the idea of creating snapshots for
+block devices. The Linux kernel already has mechanisms for creating snapshots.
+Device Mapper includes dm-snap, which allows to create snapshots of block
+devices. BTRFS supports snapshots at the file system level. However, both
+of these options have flaws that do not allow to use them as a universal
+tool for creating backups.
+
+Device Mapper flaws:
+
+- Block devices must have LVM markup.
+  If no logical volumes were created during system installation, then dm-snap
+  cannot be applied.
+- To store snapshot differences of one logical volume, it is necessary to
+  reserve a fixed range of sectors on a reserved empty logical volume.
+  Firstly, it is required that the system has enough space unoccupied by the
+  file system, which rarely occurs on real servers. Secondly, as a rule,
+  it is necessary to create snapshots for all logical volumes at once, which
+  requires dividing this reserved space between several logical volumes.
+  This space can be divided equally or proportionally to the size. But
+  the load on different disks is usually uneven. As a result, a snapshot
+  overflow may occur for one of the block devices, while for others all
+  the reserved space may remain free. This complicates management of the
+  difference storage and makes it almost impossible to create a coherent
+  snapshot of multiple logical volumes.
+
+BTRFS flaws:
+
+- Snapshots create a persistent image of the file system, not a block device.
+  Such a snapshot is only applicable for a file backup.
+- When synchronizing the snapshot subvolume with the backup subvolume, reading
+  the differences leads to random access to the block device, which leads
+  to decrease in efficiency compared to direct copying of the block device.
+- BTRFS allows to get an incremental backup [#btrfs_increment]_, but it is
+  necessary to keep a snapshot of the previous backup cycle on the system,
+  which leads to excessive consumption of disk space.
+- If there is not enough free space on the file system while holding the
+  snapshot, new data cannot be saved, which leads to a server malfunction.
+
+Features of the blksnap module:
+
+- Change tracker
+- Snapshots at the block device level
+- Dynamic allocation of space for storing differences
+- Snapshot overflow resistance
+- Coherent snapshot of multiple block devices
+
+
+For a more detailed description of the features, see the `Features`_ section.
+
+The listed set of features allows to achieve the key goals of the backup tool:
+
+- Simplicity and versatility of use
+- Reliability
+- Minimal consumption of system resources during backup
+- Minimal time required for recovery or replication of the entire system
+
+Features
+========
+
+Change tracker
+--------------
+
+The change tracker allows to determine which blocks were changed during the
+time between the last snapshot created and any of the previous snapshots.
+Having a map of changes, it is enough to copy only the changed blocks, and
+no need to reread the entire block device completely. The change tracker
+allows to implement the logic of both incremental and differential backups.
+Incremental backup is critical for large file repositories whose size can be
+hundreds of terabytes and whose full backup time can take more than a day.
+On such servers, the use of backup tools without a change tracker becomes
+practically impossible.
+
+Snapshot at the block device level
+----------------------------------
+
+A snapshot at the block device level allows to simplify the backup algorithm
+and reduce consumption of system resources. It also allows to perform linear
+reading of disk space directly, which allows to achieve maximum reading speed
+with minimal use of processor time. At the same time, the versatility of
+creating snapshots for any block device is achieved, regardless of the file
+system located on it. The exceptions are BTRFS, ZFS and cluster file systems.
+
+Dynamic allocation of storage space for differences
+---------------------------------------------------
+
+To store differences, the module does not require a pre-reserved block
+device range. A range of sectors can be allocated on any block device
+immediately before creating a snapshot in individual files on the file
+system. In addition, the size of the difference storage can be increased
+after the snapshot is created by adding new sector ranges on block devices.
+Sector ranges can be allocated on any block devices of the system, including
+those on which the snapshot was created. A shared difference storage for
+all images of snapshot block devices allows to optimize the use of disk space.
+
+Snapshot overflow resistance
+----------------------------
+
+To create images of snapshots of block devices, the module stores blocks
+of the original block device that have been changed since the snapshot
+was taken. To do this, the module handles write requests and reads blocks
+that need to be overwritten. This algorithm guarantees safety of the data
+of the original block device in the event of an overflow of the snapshot,
+and even in the case of unpredictable critical errors. If a problem occurs
+during backup, the difference storage is released, the snapshot is closed,
+no backup is created, but the server continues to work.
+
+Coherent snapshot of multiple block devices
+-------------------------------------------
+
+A snapshot is created simultaneously for all block devices for which a backup
+is being created, ensuring their coherent state.
+
+
+Algorithms
+==========
+
+Overview
+--------
+
+The blksnap module is a block-level filter. It handles all write I/O units.
+The filter is attached to the block device when the snapshot is created
+for the first time. The change tracker marks all overwritten blocks.
+Information about the history of changes on the block device is available
+while holding the snapshot. The module reads the blocks that need to be
+overwritten and stores them in the difference storage. When reading from
+a snapshot image, reading is performed either from the original device or
+from the difference storage.
+
+Change tracking
+---------------
+
+A change tracker map is created for each block device. One byte
+of this map corresponds to one block. The block size is set by the
+``tracking_block_minimum_shift`` and ``tracking_block_maximum_count``
+module parameters. The ``tracking_block_minimum_shift`` parameter limits
+the minimum block size for tracking, while ``tracking_block_maximum_count``
+defines the maximum allowed number of blocks. The size of the change tracker
+block is determined depending on the size of the block device when adding
+a tracking device, that is, when the snapshot is taken for the first time.
+The block size must be a power of two.
+
+The byte of the change map stores a number from 0 to 255. This is the
+snapshot number, since the creation of which there have been changes in
+the block. Each time a snapshot is created, the number of the current
+snapshot is increased by one. This number is written to the cell of the
+change map when writing to the block. Thus, knowing the number of one of
+the previous snapshots and the number of the last snapshot, one can determine
+from the change map which blocks have been changed. When the number of the
+current change reaches the maximum allowed value for the map of 255, at the
+time when the next snapshot is created, the map of changes is reset to zero,
+and the number of the current snapshot is assigned the value 1. The change
+tracker is reset, and a new UUID is generated - a unique identifier of the
+snapshot generation. The snapshot generation identifier allows to identify
+that a change tracking reset has been performed.
+
+The change map has two copies. One copy is active, it tracks the current
+changes on the block device. The second copy is available for reading
+while the snapshot is being held, and contains the history up to the moment
+the snapshot is taken. Copies are synchronized at the moment of snapshot
+creation. After the snapshot is released, a second copy of the map is not
+needed, but it is not released, so as not to allocate memory for it again
+the next time the snapshot is created.
+
+Copy on write
+-------------
+
+Data is copied in blocks, or rather in chunks. The term "chunk" is used to
+avoid confusion with change tracker blocks and I/O blocks. In addition,
+the "chunk" in the blksnap module means about the same as the "chunk" in
+the dm-snap module.
+
+The size of the chunk is determined by the ``chunk_minimum_shift`` and
+``chunk_maximum_count`` module parameters. The ``chunk_minimum_shift``
+parameter limits the minimum size of the chunk, while ``chunk_maximum_count``
+defines the maximum allowed number of chunks. The size of the chunk is
+determined depending on the size of the block device at the time of taking the
+snapshot. The size of the chunk must be a power of two. One chunk is described
+by the ``struct chunk`` structure. An array of structures is created for each
+block device. The structure contains all the necessary information to copy
+the chunks data from the original block device to the difference storage.
+This information allows to describe the snapshot image. A semaphore is located
+in the structure, which allows synchronization of threads accessing the chunk.
+
+The block level has a feature. If a read I/O unit was sent, and a write I/O
+unit was sent after it, then a write can be performed first, and only then
+a read. Therefore, the copy-on-write algorithm is executed synchronously.
+If a write request is handled, the execution of this I/O unit will be
+delayed until the overwritten chunks are copied to the difference storage.
+But if, when handling a write I/O unit, it turns out that the recorded range
+of sectors has already been copied to the difference storage, then the I/O
+unit is simply passed.
+
+This algorithm allows to efficiently perform backups of systems that run
+Round Robin Database. Such databases can be overwritten several times during
+the system backup. Of course, the value of a backup of the RRD monitoring
+system data can be questioned. However, it is often a task to make a backup
+of the entire enterprise infrastructure in order to restore or replicate it
+entirely in case of problems.
+
+There is also a flaw in the algorithm. When overwriting at least one sector,
+an entire chunk is copied. Thus, a situation of rapid filling of the difference
+storage when writing data to a block device in small portions in random order
+is possible. This situation is possible in case of strong fragmentation of
+data on the file system. But it must be borne in mind that with such data
+fragmentation, performance of systems usually degrades greatly. So, this
+problem does not occur on real servers, although it can easily be created
+by artificial tests.
+
+Difference storage
+------------------
+
+The difference storage is a pool of disk space areas, and it is shared with
+all block devices in the snapshot. Therefore, there is no need to divide
+the difference storage area between block devices, and the difference storage
+itself can be located on different block devices.
+
+There is no need to allocate a large disk space immediately before creating
+a snapshot. Even while the snapshot is being held, the difference storage
+can be expanded. It is enough to have free space on the file system.
+
+Areas of disk space can be allocated on the file system using fallocate(),
+and the file location can be requested using Fiemap Ioctl or Fibmap Ioctl.
+Unfortunately, not all file systems support these mechanisms, but the most
+common XFS, EXT4 and BTRFS file systems support it. BTRFS requires additional
+conversion of virtual offsets to physical ones.
+
+While holding the snapshot, the user process can poll the status of the module.
+When free space in the difference storage is reduced to a threshold value, the
+module generates an event about it. The user process can prepare a new area
+and pass it to the module to expand the difference storage. The threshold
+value is determined as half of the value of the ``diff_storage_minimum``
+module parameter.
+
+If free space in the difference storage runs out, an event is generated about
+the overflow of the snapshot. Such a snapshot is considered corrupted, and
+read I/O units to snapshot images will be terminated with an error code.
+The difference storage stores outdated data required for snapshot images,
+so when the snapshot is overflowed, the backup process is interrupted,
+but the system maintains its operability without data loss.
+
+How to use
+==========
+
+Depending on the needs and the selected license, you can choose different
+options for managing the module:
+
+- Using ioctl directly
+- Using a static C++ library
+- Using the blksnap console tool
+
+Using ioctl
+-----------
+
+The module provides the ``include/uapi/blksnap.h`` header file. It describes
+all the available ioctl and structures for interacting with the module.
+Each ioctl and structure is documented in detail. The general algorithm
+for calling control requests is approximately the following:
+
+1. ``blk_snap_ioctl_snapshot_create`` initiates the snapshot
+   creation process.
+2. ``blk_snap_ioctl_snapshot_append_storage`` allows to add the first range of
+   blocks to store changes.
+3. ``blk_snap_ioctl_snapshot_take`` creates block devices of block device
+   snapshot images.
+4. ``blk_snap_ioctl_snapshot_collect`` and
+   ``blk_snap_ioctl_snapshot_collect_images`` allow to match the original
+   block devices and their corresponding snapshot images.
+5. Snapshot images are being read from block devices whose numbers were received
+   when calling ``blk_snap_ioctl_snapshot_collect_images``. Snapshot images also
+   support the write operation. So, the file system on the snapshot image can be
+   mounted before backup, which allows to perform the necessary preprocessing.
+6. ``blk_snap_ioctl_tracker_collect`` and
+   ``blk_snap_ioctl_tracker_read_cbt_map`` allow to get data of the change
+   tracker. If a write operation was performed for the snapshot, then the change
+   tracker takes this into account. Therefore, it is necessary to receive
+   tracker data after write operations have been completed.
+7. ``blk_snap_ioctl_snapshot_wait_event`` allows to track the status of
+   snapshots and receive events about the requirement to expand the difference
+   storage or about snapshot overflow.
+8. The difference storage is expanded using
+   ``blk_snap_ioctl_snapshot_append_storage``.
+9. ``blk_snap_ioctl_snapshot_destroy`` releases the snapshot.
+10. If, after creating a backup, postprocessing is performed that changes the
+    backup blocks, it is necessary to mark such blocks as dirty in the change
+    tracker table. ``blk_snap_ioctl_tracker_mark_dirty_blocks`` is used for
+    this.
+11. It is possible to disable the change tracker from any block device using
+    ``blk_snap_ioctl_tracker_remove``.
+
+Static C++ library
+------------------
+
+The [#userspace_libs]_ library was created primarily to simplify creation of
+tests in C++, and it is also a good example of using the module interface.
+When creating applications, direct use of control calls is preferable.
+However, the library can be used in an application with a GPL-2+ license,
+or a library with an LGPL-2+ license can be created, with which even a
+proprietary application can be dynamically linked.
+
+blksnap console tool
+--------------------
+
+The blksnap [#userspace_tools]_ console tool allows to control the module
+from the command line. The tool contains detailed built-in help. To get
+the list of commands, enter the ``blksnap --help`` command. The ``blksnap
+<command name> --help`` command allows to get detailed information about the
+parameters of each command call. This option may be convenient when creating
+proprietary software, as it allows not to compile with the open source code.
+At the same time, the blksnap tool can be used for creating backup scripts.
+For example, rsync can be called to synchronize files on the file system of
+the mounted snapshot image and files in the archive on a file system that
+supports compression.
+
+Tests
+-----
+
+A set of tests was created for regression testing [#userspace_tests]_.
+Tests with simple algorithms that use the ``blksnap`` console tool to
+control the module are written in Bash. More complex testing algorithms
+are implemented in C++. Documentation [#userspace_tests_doc]_ about them
+can be found on the project repository.

[PATCH v2 09/21] block, blksnap: attaching and detaching the filter and handling I/O units

[Sergei Shtepa]

The struct tracker contains callback functions for handling a I/O units
of a block device. When a write request is handled, the change block
tracking (CBT) map functions are called and initiates the process of
copying data from the original block device to the change store.
Attaching and detaching the tracker is provided by the functions
bdev_filter_*() of the kernel.

[PATCH v2 12/21] block, blksnap: buffer in memory for the minimum data storage unit

[Sergei Shtepa]

The struct diff_buffer describes a buffer in memory for the minimum data
storage block of the original block device (struct chunk).
Buffer allocation and release functions allow to reduce the number of
allocations and releases of a large number of memory pages.

[PATCH v2 15/21] block, blksnap: event queue from the difference storage

[Sergei Shtepa]

Provides transmission of events from the difference storage to the user
process. Only two events are currently defined. The first is that there
are few free regions in the difference storage. The second is that the
request for a free region for storing differences failed with an error,
since there are no more free regions left in the difference storage
(the snapshot overflow state).

[PATCH v2 16/21] block, blksnap: owner of information about overwritten blocks of the original block device

[Sergei Shtepa]

This is perhaps the key component of the module. It stores information
about the modified blocks of the original device and the location of the
regions where these blocks are stored in the difference storage.
This information allows to restore the state of the block device at the
time of taking the snapshot and represent the snapshot image as a block
device.
When reading from a snapshot, if the block on the original device has
not yet been changed since the snapshot was taken, then the data is read
from the original block device. If the data on the original block device
has been overwritten, then the block is read from the difference
storage. Reads and writes are performed with minimal data storage blocks
(struct chunk).

+ * struct diff_area - Discribes the difference area for one original device.
+ * @kref:

+ *	the &struct tracker and &struct snapimage.
+ * @orig_bdev:
+ *	A pointer to the structure of an opened block device.
+ * @diff_storage:
+ *	Pointer to difference storage for storing difference data.
+ * @chunk_shift:
+ *	Power of 2 used to specify the chunk size. This allows to set different chunk sizes for
+ *	huge and small block devices.
+ * @chunk_count:
+ *	Count of chunks. The number of chunks into which the block device
+ *	is divided.
+ * @chunk_map:
+ *	A map of chunks.
+ * @caches_lock:
+ *	This spinlock guarantees consistency of the linked lists of chunk
+ *	caches.
+ * @read_cache_queue:
+ *	Queue for the read cache.
+ * @read_cache_count:
+ *	The number of chunks in the read cache.
+ * @write_cache_queue:
+ *	Queue for the write cache.
+ * @write_cache_count:
+ *	The number of chunks in the write cache.
+ * @cache_release_work:
+ *	The workqueue work item. This worker limits the number of chunks
+ *	that store their data in RAM.
+ * @free_diff_buffers_lock:
+ *	This spinlock guarantees consistency of the linked lists of
+ *	free difference buffers.
+ * @free_diff_buffers:
+ *	Linked list of free difference buffers allows to reduce the number
+ *	of buffer allocation and release operations.
+ * @free_diff_buffers_count:
+ *	The number of free difference buffers in the linked list.
+ * @corrupt_flag:
+ *	The flag is set if an error occurred in the operation of the data
+ *	saving mechanism in the diff area. In this case, an error will be
+ *	generated when reading from the snapshot image.
+ * @pending_io_count:
+ *	Counter of incomplete I/O operations. Allows to wait for all I/O
+ *	operations to be completed before releasing this structure.
+ *
+ * The &struct diff_area is created for each block device in the snapshot.
+ * It is used to save the differences between the original block device and
+ * the snapshot image. That is, when writing data to the original device,
+ * the differences are copied as chunks to the difference storage.
+ * Reading and writing from the snapshot image is also performed using
+ * &struct diff_area.
+ *
+ * The xarray has a limit on the maximum size. This can be especially
+ * noticeable on 32-bit systems. This creates a limit in the size of
+ * supported disks.
+ *
+ * For example, for a 256 TiB disk with a block size of 65536 bytes, the
+ * number of elements in the chunk map will be equal to 2 with a power of 32.
+ * Therefore, the number of chunks into which the block device is divided is
+ * limited.
+ *
+ * To provide high performance, a read cache and a write cache for chunks are
+ * used. The cache algorithm is the simplest. If the data of the chunk was
+ * read to the difference buffer, then the buffer is not released immediately,
+ * but is placed at the end of the queue. The worker thread checks the number
+ * of chunks in the queue and releases a difference buffer for the first chunk
+ * in the queue, but only if the binary semaphore of the chunk is not locked.
+ * If the read thread accesses the chunk from the cache again, it returns
+ * back to the end of the queue.
+ *
+ * The linked list of difference buffers allows to have a certain number of
+ * "hot" buffers. This allows to reduce the number of allocations and releases
+ * of memory.

[PATCH v2 17/21] block, blksnap: snapshot image block device

[Sergei Shtepa]

Provides the operation of block devices of snapshot images. Read and
write operations are redirected to the regions of difference blocks for
block device (struct diff_area).

[PATCH v2 18/21] block, blksnap: snapshot

[Sergei Shtepa]

The struck snapshot combines block devices, for which a snapshot is
created, block devices of their snapshot images, as well as a difference
storage.
There may be several snapshots at the same time, but they should not
contain common block devices. This can be used for cases when backup is
scheduled once an hour for some block devices, and once a day for
others, and once a week for others. In this case, it is possible that
three snapshots are used at the same time.

Per convention in block subsystem (see for example `git log --no-merges
-- drivers/block/`), the patch subject prefix should looks like "block
component: some patch" (e.g. "blksnap: do something").

The patch subject should be "Documentation: document Block Devices
Snapshots Module".

Don't forget to write the description in imperative mood instead.

There is a jump from drawbacks of existing method to blksnap features.
Before introducing the latter, there should have been blksnap
description and how it solves the drawbacks. Also, the features list
above is redundant due to features section which describes each of them.

IMO this section should be placed after "How to use" section, because
it's quite odd to add another info after references section.

Thanks for spotting this, I think this is not related to blkfilter patch 
but was already wrong/broken before and should be posted in a single 
patch out of the blksnap serie (also fixing title, as reported by Bagas 
Sanjaya, like "documentation: fix Generic Block Device Capability")

from a fast look seems to me should have only:

+    :DOC: genhd capability flags

and out of that looking older version of doc 
(https://www.kernel.org/doc/html/v5.10/block/capability.html) seems to 
me that this DOC in blkdev.h need improvement as it seems to me it was 
better in the past, for example also reporting the corresponding 
hexadecimal value in parentheses

I don't think we need the quiesce here (or in the detach path).
quiesce works as the low-level blk-mq dispatch level, and we
sit way above that.

Please use EXPORT_SYMBOL_GPL for new low-level block layer features.

Not having a filter is a grave error that the caller can't do
anything about.  So pleas just WARN_ON_ONCE for that case, and
change the function to a void return.

Instead of ending the bio here for the !pass case it seems to me it
would make more sense to just pass ownership to the filter driver and
let the driver complete it.  That would allow error returns for that
case, or handling it from a workqueue.  I'd also change the polarity
so that true means "I've taken ownership".  I.e.:

	if (bio->bi_bdev->bd_filter && !bio_flagged(bio, BIO_FILTERED)) {
		bio_set_flag(bio, BIO_FILTERED);
		if (bio->bi_bdev->bd_filter->fops->submit_bio_cb(bio))
			return;
	}

Nit:  I don't think these _cb postfixes are very useful.  All methods
in a method table are sort of callbacks.

Looking at the callers in blksnap I'm not sure this works.  The
pattern seems to be the driver has a block device reference, and
then uses bdev_filter_get to grab a filter reference.  But what
prevents the filter from going away just bdev_filter_get is called?
At a minimum we'd need a something:

static inline struct bdev_filter *bdev_filter_get(struct block_device *bdev)
{
	struct bdev_filter *flt;

	rcu_read_lock();
	flt = rcu_dereference(bdev->bd_filter);
	if (!refcount_inc_not_zero(&flt->refs))
		flt = NULL;
	rcu_read_unlock();

	return flt;
}


with bd_filter switched to __rcu annotation, the kref replaced with
a refcount_t, updates switched to cmpxchg and a rcu_synchronize()
after clearing bd_filter.

This crashed when blksnap is built into the kernel because THIS_MODULE
is NULL for that case.

But I think most of this boilerplate can be removed - just use a misc
device and use /proc/misc to find the major from userspace if anything
cares, but nothing should as the misc devices already create the
node through udev.  I.e.g:

You need to clean up all these initialization if a later one fails.

Also, does this really need a separate file?  Any good reason to
not just keep the tiny amount of init code in ctrl.c?

Also we try to avoid these verbose messages for new code normally.

There's not need to grab and put an extra reference to the task_struct,
the kthread code already holds one.

Do you need a timeout sleep here?  All new arrivals should properly

It seems like the loop could be simplified to:

	for (;; {
		while ((bio = get_bio_from_queue(snapimage)))
			snapimage_process_bio(snapimage, bio);
		if (kthread_should_stop())
			break;
		schedule();
	}

I think you can do away with the is_ready flag entirely by just
calling del_gendisk early enough.  See below.

Just move the snapimage_stop_worker after del_gendisk here, and
you should be fine.

.. and then implement the free_disk block_device operation, and
move all code after the put_disk into it, which means all your

GENHD_FL_NO_PART_SCAN is gone, so this ifdef goes away.

No new driver should manage the major/minor numbers manually, as
the block layer just assigns a dev_t by default if you don't se these.

I don't think this wake_up is needed - the first queue bio should
wake the helper thread up.

And with block layer managed dev_t all this boilerplate can go away
as well.

If you already include blk-mq.h, there is no need for the other two
headers as they are already implictly included.

We're called through the filter, so checking this again here (twice)
is a bit silly.

Does it make sense to make this a global lock vs per-struct tracker?

Just nitpicking, but what about moving all the code below here
into a separate helper that is only called for op_is_write &&
bio_sectors?  It's not going to change anything functionally, but
would make the code easier to follow.

barrier is just a compiler barrier, so it is unlikely to do what
you want. But without a comment I can't even figure out what it is
trying to do.

I think you need to fail the attachment if we can't freeze the device.

This defeats the reason to move it to the workqueue first, as you
can still deadlock on whatever problem that tried to solve, just
out of reach of lockdep.

These blkdev_get_by_dev calls are a little problematic, as they
bypass any access restriction (LSMs, containers, etc).  That's
why the kernel generally does a blkdev_get_by_name based on the
actual file name, which does all the proper checks.  I think the
tracker creation also needs to happen based on names to fit into this
security model.  Passing in names should also be much easier for
userspace to start with.


Now for remove, and the other operations on the tracked device:
Is there any reason to not simply add an ioctl method to
bdev_filter_operations, so that you can issue these ioctls against the
tracked device?  That removes the need to find the tracked device
entirely and should simplify a lot of things.

In fact thinking wonder if attachment of a filter driver should
go through the block layer using an ioctl on the tracked device
as well, i.e.

 - add a name field to bdev_filter_operations
 - keep a list of all bdev_filter_operations in the block core
 - new core block layer ioctl to associate a block device with a
   bdev_filter_operations
 - everything after that is done through bdev_filter_operations->ioctl.

bio_alloc_bioset can't fail for the !is_nowait case.

I am very glad to see your comments, Christoph.
Thank you so much for the review.

I have read all the comments and agree with them.
Now I see new ways to make the code of the filter and the blksnap module better.
There seems to be a lot of work to be done. :)

Sorry for being so late, but I was stuck onder a pile of work last
time you posted it.  But compared to the versions before I think we've
made a lot of progress and we'll get there.  Also feel free to ask me
for input on changes before the sending the whole series if you have any

Hi, after a fast look to the git history the "genhd capability flags" 
DOC was changed in commit 430cc5d3ab4d0ba0bd011cfbb0035e46ba92920c 
(block: cleanup the GENHD_FL_* definitions) as part of 
https://lore.kernel.org/all/20211122130625.1136848-1-hch@lst.de/ and 
after that in Documentation/block/capability.rst is not possible 
"decode" /sys/block/<disk>/capability reading it 
(https://www.kernel.org/doc/html/v6.1/block/capability.html) without 
having to read also include/linux/blkdev.h code, or I'm wrong?

is correct readd the hexadecimal value from bitfield?

Yes, this function will be rewritten to eliminate unnecessary wake-ups.
The code that Christoph proposed in the letter at Dec 15 should work well.

Minor nit:
The following could be done to keep it consistent with other functions:

	if (copy_from_user(dirty_blocks_array, (void *)karg.dirty_blocks_array,

[this reply got long...]

I think it is important to revisit how we've gotten to this point.
The catalyst for blkfilter and now blksnap was that I removed the
export for blk_mq_submit_bio -- which veeam was using for enablement
of their commercial backup software product, the offending commit was 
681cc5e8667e ("dm: fix request-based DM to not bounce through indirect dm_submit_bio")

The way veeam started to address this change was to request Red Hat
modify RHEL (by reverting my change in RHEL8, whereby restoring the
export) to give them a stopgap while they worked to identify a more
lasting solution to them having depended on such a fragile interface
with which to hijack IO for all Linux block devices.

They then came up with blk-interposer.  I tried to be helpful and
replied quite regularly to blk-interposer patchsets, e.g.:
https://listman.redhat.com/archives/dm-devel/2021-March/045900.html
https://listman.redhat.com/archives/dm-devel/2021-March/045838.html
(I won't dig out more pointers, but can if you doubt this assertion).
The last reply I got on this topic was very dense and so I
tabled it with the idea of revisiting it. But I dropped the ball and
never did reply to this:
https://listman.redhat.com/archives/dm-devel/2021-April/046184.html

Sorry. But that wasn't out of malice. I was just busy with other
things and blk-interposer took the back seat. I never imagined that my
inaction would foster completely abandoning the approach.

But my thanks is I'm now made to defend myself on LWN:
https://lwn.net/Articles/920245/
https://lwn.net/Articles/920249/

I happened to trip over that LWN thread because I saw Hannes reference
"blksnap" as something that somehow is a tolerated advance but other
efforts are not:
https://lore.kernel.org/linux-block/06e4d03c-3ecf-7e91-b80e-6600b3618b98@suse.de/

blksnap really needs to stand on its own merits and it could be that
in conjunction with blkfilter it does. But the way it has evolved has
been antithetical to how to properly engage the Linux community and
subsystem mainatiners like myself. The PR campaign to raise awareness
with LWN became more important than cc'ing me. That says it all
really.

But hopefully you can take my words as my truth: I think what you're
wanting to do is useful. I never intended to act as some gatekeeper. I
don't have a problem with what your goals are, I just ask that _how_
you achieve your goals be done with care and consideration (the
attempts I reviewed prior to your most recent work were lacking).

But my one and only request for this line of development would be: I
_really_ want DM code to be able to used as an endpoint for IO
remapping associated with any new block core hook added to accomplish
dynamic remapping of IO.  If I need to take an active role in the
development of that capability, so be it.

I've yet to look closely at all this code (but wow there is quite a
lot under drivers/block/blksnap).  I'll have a look at the block-core
changes and then try to make sense of things from there.

But you've already bypassed me, my hope is that Jens and Christoph
agree that we need this line of development to be in service to other
areas of the Linux block subsystem and its drivers that were
established for the purposes of remapping IO.  It cannot just be
the subset needed to cement veeam's ability to use Linux for its 
purposes (but I completely understand that is the point of veeam's
exercise).

Thank you so much for your help with the function blk_mq_submit_bio().
This fix helped the veeamsnap module to continue working on RHEL 8
with a minimal set of crutches. But besides RHEL 8, there are other
distributions that required support.

The catalyst was the optimization of Christoph and the removal of
the make_request_fn() callback function in v5.9. See:
https://elixir.bootlin.com/linux/v5.8.18/source/include/linux/blkdev.h#L406
Overriding this function allowed handling I/O units.

And yes, I’ve spent several months trying to refine the DM in order to
implement the feature of attaching DM devices on the fly, that you said you
would like to have in DM. Alas, I have not achieved success. I figured that
it would take a lot of changes in the DM code before its non-persistent
snapshots can be used for backup, and some architectural changes will be
required. Although you have been very helpful for a while, at some point
you stopped providing any feedback and thus I started to explore other
possibilities to solve the problem.

Seeing your annoyance now, I wonder what would be the better way to continue
my work in the given circumstances? What kind of action would you expect from
me in such situation? Being left without any feedback and guidance on DM,
I decided to work directly with the community to find better solution.

That is, I took another route (blksnap) not because I thought the initial 
DM-based approach proposed by you was inferior or bad, but because only this
direction remained available to me.

As for the article on LWN:

I am very grateful to Jonathan for his article. It attract some attention
to my work. However, it’s wasn’t a deliberate PR company from Veeam.
In fact, Veeam has nothing to do with the article.

Yes, I work for the company, but the company has neither requested the
article, nor has started any other PR regarding the matter.

If I were organizing a PR campaign, the article would be similar to this:
https://github.com/veeam/blksnap/blob/master/doc/Something-wrong-with-snapshots-for-Linux.md
But be careful! In the article I try to change the reader's opinion about
snapshots. Feedback, as usual, is welcome.

Mike, I assure you, I have one goal. Snapshots of block devices in the
Linux kernel for backup.

I think we got off to a good start initially, but then something went wrong 
(miscommunications, misunderstanding, and a lack of time) so here we are.
If you could clarify what could have been the proper way of dealing with
that situation from my side, I would really appreciate that.

I am sure that this is quite achievable. If the dm-dev team has special
needs when attaching DM devices via blkfilter, we will be able to upgrade it.
At the moment I don't see any problems with this.
I can promise you to add you to СС when sending next patches.

Sounds good?

Yes, that's right. There are quite a few changes in block-core.
From the blksnap, it is enough to view tracker.c. I/O handling is
implemented there.
But it's probably better to wait for the next version of patch that takes
into account Christoph's comments. There are a lot of changes, and first
of all in the interface.

It’s not about Veeam at all. I am sure that my work will help many backup 
vendors and average users to build more robust and efficient backup tools.
So, the argument that I do it just because Veeam needs it does not hold
any water – I know that many people need the feature, not just Veeam.

I'm late to respond to your email again because Red Hat now imposes
gmail and its mail filtering is abysmal. I should just use
snitzer@kernel.org since it is able to ensure I am aware of
replies.. anyway, that's my problem to sort out! ;)

You're fine to approach the implementation however you and others
think best.  I have a couple core points I'll raise in the block core
patch.

But yes, I was hoping we could effectively make it so that any block
device could be augmented to remap bios (either in terms of existing
DM targets or a more minimalist approach that meets your snapshot
needs).

Feels somewhat like failure to not be able to make that advancement,
but nothing is "done" yet... let's see what we can do.

We can just move past all that. No lasting issue. I took the comments

I will have to look closer at how you're able to ensure consistency
between upper layer (FS) and the block layer.  The fsfreeze hooks were
added long ago with FS-to-block consistency (ensuring IO flushed and
halted, etc).

No other snapshot consumers have shown themselves. Using them as some
sort of implied consensus on what is needed for generic Linux snapshot
is a bit of a leap. All you really have are your requirements. Doesn't
really help to say you represent the interests of all interested
parties if they remain nameless and in the background.

What about bio-based devices? (DM, MD, etc)

DM uses freeze_bdev() and thaw_bdev(), seems like you're missing some
work here.

Shouldn't this be: if (unlikely(...))?

But that obviously assumes a fair amount about the only consumer
(temporary filter that lasts as long as it takes to do a backup).

And you currently don't allow for blkfilter to be involved if a bio
recurses (which is how bio splitting works now).  Not sure it
matters, just mentioning it...

But taking a step back, in the hopes of stepping out of your way:

Myself and others on the DM team (past and present) have always hoped
all block devices could have the flexibility of DM. It was that hope
that caused my frustration when I first saw your blkfilter approach.

But I was too idealistic that a byproduct of your efforts
(blk-interposer before and blkfilter now) would usher in _all_ block
devices being able to comprehensively change their identity (and IO
processing) like DM enjoys.

DM showcases all the extra code needed to achieve its extreme IO
remapping and stacking flexibilty -- I don't yet see a way to distill
the essence of what DM achieves without imposing too much on all block
core.

So I do think blkfilter is a pragmatic way to achieve your goals.

All you really have are your requirements. Doesn't really help to say you represent the interests of all interested parties if they remain nameless and in the background.

I'm speaking on behalf of Comet Backup, another commercial vendor in this space. I just want to chime in and say we're very closely following the development of this patch set. 

Our end-user customers have an "arbitrary" Linux system where we don't control the filesystem or block device layer. Having a point-in-time consistent snapshot is essential for a high quality backup, and it's table-stakes on Windows with the VSS subsystem. But a very large number of installs in-the-wild are using plain ext4 without lvm, and we have no remaining viable mechanisms for either filesystem-level or block device-level backup.

For this use case, the snapshots are generally short-lived. The underlying mechanism doesn't affect us much - whether it's live-swapping DM devices, or explicitly tracking bio's (or if somehow ext4 and xfs magically got fs-level snapshotting support). But most of all, we'd love to see something upstream.

I'd also point you towards Datto's out-of-tree 'dattobd' block device driver with the same objective: https://github.com/datto/dattobd (LGPLv2+). It was working in a slightly different way by using ftrace to hook submit_bio_noacct.

Hi, thanks for review this project that I think is very useful and I 
hope it will be able to reach a very good quality, that will be 
integrated into the kernel and that more backup solutions will use it 
improving backups on linux in several cases.
In the last month Sergei made big changes, applying Christoph Hellwig 
changes and working following the received replies, the new version of 
the patch is not ready yet but the many changes done for now are 
available here: https://github.com/SergeiShtepa/linux/commits/blksnap-master
I suppose that full review now of v2 when many things was already 
changed for next version can risk to waste time. I hope I've helped with 
this, if I haven't, sorry to have bother you.

Thanks, Mike.

We are planning to add a freeze_bdev() function call in bdev_filter_attach().
But for the bdev_filter_detach() function, it doesn't seem to make sense.
I think enough to call blk_mq_freeze_queue().

As Fabio already wrote, I use a public repository on github to work with
the patch: https://github.com/SergeiShtepa/linux/commits/blksnap-master
The current state can be viewed there. Feedback is welcome as usual.

Yes, at the moment the code is being created so that only one filter
is possible. In the summer, I offered a more complex solution, in which
there were altitudes. See:
https://lore.kernel.org/linux-block/1655135593-1900-2-git-send-email-sergei.shtepa@veeam.com/
But this is redundant code for this task at the moment, since only
one filter is offered now. I think it will be possible to implement
something similar later.
