The patch series covers the points discussed in November 2021 virtual
call [LSF/MM/BFP TOPIC] Storage: Copy Offload [0].
We have covered the initial agreed requirements in this patchset and
further additional features suggested by community.
Patchset borrows Mikulas's token based approach for 2 bdev
implementation.
This is on top of our previous patchset v4[1].
Overall series supports:
========================
1. Driver
- NVMe Copy command (single NS, TP 4065), including support
in nvme-target (for block and file backend).
2. Block layer
- Block-generic copy (REQ_COPY flag), with interface
accommodating two block-devs, and multi-source/destination
interface
- Emulation, when offload is natively absent
- dm-linear support (for cases not requiring split)
3. User-interface
- new ioctl
- copy_file_range for zonefs
4. In-kernel user
- dm-kcopyd
- copy_file_range in zonefs
Testing
=======
Copy offload can be tested on:
a. QEMU: NVME simple copy (TP 4065). By setting nvme-ns
parameters mssrl,mcl, msrc. For more info [2].
b. Fabrics loopback.
c. zonefs copy_file_range
Emuation can be tested on any device.
Sample application to use IOCTL is present in patch desciption.
fio[3].
Performance
===========
With the async design of copy-emulation/offload using fio[3],
we were able to see the following improvements as
compared to userspace read and write on a NVMeOF TCP setup:
Setup1: Network Speed: 1000Mb/s
Host PC: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz
Target PC: AMD Ryzen 9 5900X 12-Core Processor
block size 8k, range 1:
635% improvement in IO BW (107 MiB/s to 787 MiB/s).
Network utilisation drops from 97% to 14%.
block-size 2M, range 16:
2555% improvement in IO BW (100 MiB/s to 2655 MiB/s).
Network utilisation drops from 89% to 0.62%.
Setup2: Network Speed: 100Gb/s
Server: Intel(R) Xeon(R) Gold 6240 CPU @ 2.60GHz, 72 cores
(host and target have the same configuration)
block-size 8k, range 1:
6.5% improvement in IO BW (791 MiB/s to 843 MiB/s).
Network utilisation drops from 6.75% to 0.14%.
block-size 2M, range 16:
15% improvement in IO BW (1027 MiB/s to 1183 MiB/s).
Network utilisation drops from 8.42% to ~0%.
block-size 8k, 8 ranges:
18% drop in IO BW (from 798 MiB/s to 647 MiB/s)
Network utilisation drops from 6.66% to 0.13%.
At present we see drop in performance for bs 8k,16k and
higher ranges (8, 16), so something more to check there.
Overall, in these tests, kernel copy emulation performs better than
userspace read+write.
Zonefs copy_file_range
======================
Sample tests for zonefs-tools[4]. Test 0118 and 0119 will test
basic CFR. Will raise a PR, once this series is finalized.
Future Work
===========
- nullblk: copy-offload emulation
- generic copy file range (CFR):
I did go through this, but couldn't find straight forward
way to plug in copy offload for all the cases. We are doing
detailed study, will address this future versions.
- loopback device copy offload support
- upstream fio to use copy offload
These are to be taken up after we reach consensus on the
plumbing of current elements that are part of this series.

Changes since v4:
=================
- make the offload and emulation design asynchronous (Hannes
Reinecke)
- fabrics loopback support
- sysfs naming improvements (Damien Le Moal)
- use kfree() instead of kvfree() in cio_await_completion
(Damien Le Moal)
- use ranges instead of rlist to represent range_entry (Damien
Le Moal)
- change argument ordering in blk_copy_offload suggested (Damien
Le Moal)
- removed multiple copy limit and merged into only one limit
(Damien Le Moal)
- wrap overly long lines (Damien Le Moal)
- other naming improvements and cleanups (Damien Le Moal)
- correctly format the code example in description (Damien Le
Moal)
- mark blk_copy_offload as static (kernel test robot)
Changes since v3:
=================
- added copy_file_range support for zonefs
- added documentation about new sysfs entries
- incorporated review comments on v3
- minor fixes
Changes since v2:
=================
- fixed possible race condition reported by Damien Le Moal
- new sysfs controls as suggested by Damien Le Moal
- fixed possible memory leak reported by Dan Carpenter, lkp
- minor fixes

Add device limits as sysfs entries,
- copy_offload (RW)
- copy_max_bytes (RW)
- copy_max_bytes_hw (RO)
Above limits help to split the copy payload in block layer.
copy_offload: used for setting copy offload(1) or emulation(0).
copy_max_bytes: maximum total length of copy in single payload.
copy_max_bytes_hw: Reflects the device supported maximum limit.

Introduce blkdev_issue_copy which supports source and destination bdevs,
and an array of (source, destination and copy length) tuples.
Introduce REQ_COPY copy offload operation flag. Create a read-write
bio pair with a token as payload and submitted to the device in order.
Read request populates token with source specific information which
is then passed with write request.
This design is courtesy Mikulas Patocka's token based copy
Larger copy will be divided, based on max_copy_sectors limit.

Introduce blkdev_issue_copy which supports source and destination bdevs,
and an array of (source, destination and copy length) tuples.
Introduce REQ_COPY copy offload operation flag. Create a read-write
bio pair with a token as payload and submitted to the device in order.
Read request populates token with source specific information which
is then passed with write request.
This design is courtesy Mikulas Patocka's token based copy
Larger copy will be divided, based on max_copy_sectors limit.

I thought this patchset is just for enabling copy command which is
supported by hardware. But turns out it isn't, because blk_copy_offload()
still submits read/write bios for doing the copy.
I am just wondering why not let copy_file_range() cover this kind of copy,
and the framework has been there.
When I was researching pipe/splice code for supporting ublk zero copy[1], I
have got idea for async copy_file_range(), such as: io uring based
direct splice, user backed intermediate buffer, still zero copy, if these
ideas are finally implemented, we could get super-fast generic offload copy,
and bdev copy is really covered too.

blk_copy_offload - actually issues copy command in driver layer.
The way read/write BIOs are percieved is different for copy offload.
In copy offload we check REQ_COPY flag in NVMe driver layer to issue
copy command. But we did missed it to add in other driver's, where they
might be treated as normal READ/WRITE.
blk_copy_emulate - is used if we fail or if device doesn't support native
copy offload command. Here we do READ/WRITE. Using copy_file_range for
emulation might be possible, but we see 2 issues here.
1. We explored possibility of pulling dm-kcopyd to block layer so that we
can readily use it. But we found it had many dependecies from dm-layer.
So later dropped that idea.
2. copy_file_range, for block device atleast we saw few check's which fail
it for raw block device. At this point I dont know much about the history of
why such check is present.

Is it just because dm-kcopyd supports async copy? If yes, I believe we
can reply on io_uring for implementing async copy_file_range, which will
be generic interface for async copy, and could get better perf.

Got it, but IMO the check in generic_copy_file_checks() can be
relaxed to cover blkdev cause splice does support blkdev.
Then your bdev offload copy work can be simplified into:
1) implement .copy_file_range for def_blk_fops, suppose it is
blkdev_copy_file_range()
2) inside blkdev_copy_file_range()
- if the bdev supports offload copy, just submit one bio to the device,
and this will be converted to one pt req to device
- otherwise, fallback to generic_copy_file_range()

BTW, that is probably one direction of ublk's async zero copy IO too.

It supports both sync and async. But used only inside dm-layer.
Async version of copy_file_range can help, using io-uring can be helpful
for user , but in-kernel users can't use uring.

We will check the feasibilty and try to implement the scheme in next versions.
It would be helpful, if someone in community know's why such checks were
present ? We see copy_file_range accepts only regular file. Was it
designed only for regular files or can we extend it to regular block
device.

It supports both sync and async. But used only inside dm-layer.
Async version of copy_file_range can help, using io-uring can be helpful
for user , but in-kernel users can't use uring.

We will check the feasibilty and try to implement the scheme in next versions.
It would be helpful, if someone in community know's why such checks were
present ? We see copy_file_range accepts only regular file. Was it
designed only for regular files or can we extend it to regular block
device.

Actually we sent initial version with single bio, but later community
suggested two bio's is must for offload, main reasoning being
dm-layer,Xcopy,copy across namespace compatibilty.

As you suggested we were able to integrate def_blk_ops and
run with user application, but we see one main issue with this approach.
Using blkdev_copy_file_range requires having 2 file descriptors, which
is not possible for in kernel users such as fabrics/dm-kcopyd which has
only bdev descriptors.
Do you have any plumbing suggestions here ?

But dm kcopy has supported bdev copy already, so once your patch is
ready, dm kcopy can just sends one bio with REQ_COPY if the device
supports offload command, otherwise the current dm kcopy code can work
as before.

What is the fabrics kernel user? Any kernel target code(such as nvme target)
has file/bdev path available, vfs_copy_file_range() should be fine.
Also IMO, kernel copy user shouldn't be important long term, especially if
io_uring copy_file_range() can be supported, forwarding to userspace not
only gets better performance, but also cleanup kernel related copy code
much.

Also IMO, kernel copy user shouldn't be important long term, especially if
io_uring copy_file_range() can be supported, forwarding to userspace not
only gets better performance, but also cleanup kernel related copy code
much.

This[1] is the starting thread for LSF/MM which Chaitanya organized and it
was a conference call. Also in 2022 LSM/MM there was a discussion on copy
topic as well. One of the main conclusion was using 2 bio's as must have.
Bart has summarized previous copy efforts[2] and Martin too [3],
which might be of help in understanding why 2 bio's are must.

In fabrics setup we are exposing target side NVMe device, to host as
copy offload capable device, irrespective of target device's capability.
This will enable sending copy offload command from host.
From target side, if device doesn't support offload then we emulate.
This way we will avoid data copy over the network.

From target side, fabrics device can be created in 2 ways,
1. file backed device: In this setup we get file descriptor. In fact in our
patches[4] are using vfs_copy_file_range to offload copy.
2. block backed device: Here we have only blockdev descriptor.
This setup we can't use vfs_copy_file_range since we are missing file
descriptor.
Your input on how we can plumb blkdev_copy_file_range with bdev would help.

Using uring is valid if consumer of copy_file_range is userspace.
But there are many possible in-kernel user of copy, such as dm-kcopyd,
garbage collection case such as F2FS GC, also fabrics as explained above.
We can't use uring from these layers.
Present implementation of vfs_copy_file_range(CFR) lacks
a. async implementation, which helps in nvme over fabrics
b. multi range(src,dst pair) support
So here we see going to blkdev_copy_file_range actually regress our present
result. But we do see a goodness of using mature vfs_copy_file_range for
emulation.

For the devices which does not support copy, copy emulation is
added. Copy-emulation is implemented by reading from source ranges
into memory and writing to the corresponding destination asynchronously.
For zoned device we maintain a linked list of read submission and try to
submit corresponding write in same order.
Also emulation is used, if copy offload fails or partially completes.

For the devices which does not support copy, copy emulation is
added. Copy-emulation is implemented by reading from source ranges
into memory and writing to the corresponding destination asynchronously.
For zoned device we maintain a linked list of read submission and try to
submit corresponding write in same order.
Also emulation is used, if copy offload fails or partially completes.

Add new BLKCOPY ioctl that offloads copying of one or more sources ranges
to one or more destination in a device. COPY ioctl accepts a 'copy_range'
structure that contains no of range, a reserved field , followed by an
array of ranges. Each source range is represented by 'range_entry' that
contains source start offset, destination start offset and length of
source ranges (in bytes)
MAX_COPY_NR_RANGE, limits the number of entries for the IOCTL and
MAX_COPY_TOTAL_LENGTH limits the total copy length, IOCTL can handle.
Example code, to issue BLKCOPY:
/* Sample example to copy three entries with [dest,src,len],
* [32768, 0, 4096] [36864, 4096, 4096] [40960,8192,4096] on same device */
int main(void)
{
int i, ret, fd;
unsigned long src = 0, dst = 32768, len = 4096;
struct copy_range *cr;
cr = (struct copy_range *)malloc(sizeof(*cr)+
(sizeof(struct range_entry)*3));
cr->nr_range = 3;
cr->reserved = 0;
for (i = 0; i< cr->nr_range; i++, src += len, dst += len) {
cr->ranges[i].dst = dst;
cr->ranges[i].src = src;
cr->ranges[i].len = len;
cr->ranges[i].comp_len = 0;
}
fd = open("/dev/nvme0n1", O_RDWR);
if (fd < 0) return 1;
ret = ioctl(fd, BLKCOPY, cr);
if (ret != 0)
printf("copy failed, ret= %d\n", ret);
for (i=0; i< cr->nr_range; i++)
if (cr->ranges[i].len != cr->ranges[i].comp_len)
printf("Partial copy for entry %d: requested %llu,
completed %llu\n",
i, cr->ranges[i].len,
cr->ranges[i].comp_len);
close(fd);
free(cr);
return ret;
}

Add new BLKCOPY ioctl that offloads copying of one or more sources ranges
to one or more destination in a device. COPY ioctl accepts a 'copy_range'
structure that contains no of range, a reserved field , followed by an
array of ranges. Each source range is represented by 'range_entry' that
contains source start offset, destination start offset and length of
source ranges (in bytes)
MAX_COPY_NR_RANGE, limits the number of entries for the IOCTL and
MAX_COPY_TOTAL_LENGTH limits the total copy length, IOCTL can handle.
Example code, to issue BLKCOPY:
/* Sample example to copy three entries with [dest,src,len],
* [32768, 0, 4096] [36864, 4096, 4096] [40960,8192,4096] on same device */
int main(void)
{
int i, ret, fd;
unsigned long src = 0, dst = 32768, len = 4096;
struct copy_range *cr;
cr = (struct copy_range *)malloc(sizeof(*cr)+
(sizeof(struct range_entry)*3));
cr->nr_range = 3;
cr->reserved = 0;
for (i = 0; i< cr->nr_range; i++, src += len, dst += len) {
cr->ranges[i].dst = dst;
cr->ranges[i].src = src;
cr->ranges[i].len = len;
cr->ranges[i].comp_len = 0;
}
fd = open("/dev/nvme0n1", O_RDWR);
if (fd < 0) return 1;
ret = ioctl(fd, BLKCOPY, cr);
if (ret != 0)
printf("copy failed, ret= %d\n", ret);
for (i=0; i< cr->nr_range; i++)
if (cr->ranges[i].len != cr->ranges[i].comp_len)
printf("Partial copy for entry %d: requested %llu,
completed %llu\n",
i, cr->ranges[i].len,
cr->ranges[i].comp_len);
close(fd);
free(cr);
return ret;
}

For device supporting native copy, nvme driver receives read and
write request with BLK_COPY op flags.
For read request the nvme driver populates the payload with source
information.
For write request the driver converts it to nvme copy command using the
source information in the payload and submits to the device.
current design only supports single source range.
This design is courtesy Mikulas Patocka's token based copy
trace event support for nvme_copy_cmd.
Set the device copy limits to queue limits.

For device supporting native copy, nvme driver receives read and
write request with BLK_COPY op flags.
For read request the nvme driver populates the payload with source
information.
For write request the driver converts it to nvme copy command using the
source information in the payload and submits to the device.
current design only supports single source range.
This design is courtesy Mikulas Patocka's token based copy
trace event support for nvme_copy_cmd.
Set the device copy limits to queue limits.

Add support for handling target command on target.
For bdev-ns we call into blkdev_issue_copy, which the block layer
completes by a offloaded copy request to backend bdev or by emulating the
request.
For file-ns we call vfs_copy_file_range to service our request.

Add support for handling target command on target.
For bdev-ns we call into blkdev_issue_copy, which the block layer
completes by a offloaded copy request to backend bdev or by emulating the
request.
For file-ns we call vfs_copy_file_range to service our request.
Currently target always shows copy capability by setting
NVME_CTRL_ONCS_COPY in controller ONCS.

Based on my understanding of the NVMe protocol 2.0, the mssrl is the
max length per single range entry,
the mcl is the total max copy length in one copy command, may I ask why
mcl = msssrl? not mcl = mssrl * msrc?

You are right, as per NVMe spec, mcl >= mssrl. Since we decided to make
copy offload generic for NVMe/Xcopy/copy across namespaces and all, we went
with 2 bio/bdev design, which is compatible with device mapper.
So effectively we are using 1 range(msrc), when using only 1 range, I
feel it makes sense to use one of the limits, so went with mssrl.

You are right, as per NVMe spec, mcl >= mssrl. Since we decided to make
copy offload generic for NVMe/Xcopy/copy across namespaces and all, we went
with 2 bio/bdev design, which is compatible with device mapper.
So effectively we are using 1 range(msrc), when using only 1 range, I
feel it makes sense to use one of the limits, so went with mssrl.

Before enabling copy for dm target, check if underlying devices and
dm target support copy. Avoid split happening inside dm target.
Fail early if the request needs split, currently splitting copy
request is not supported.

Introduce copy_jobs to use copy-offload, if supported by underlying devices
otherwise fall back to existing method.
run_copy_jobs() calls block layer copy offload API, if both source and
destination request queue are same and support copy offload.
On successful completion, destination regions copied count is made zero,
failed regions are processed via existing method.

Introduce copy_jobs to use copy-offload, if supported by underlying devices
otherwise fall back to existing method.
run_copy_jobs() calls block layer copy offload API, if both source and
destination request queue are same and support copy offload.
On successful completion, destination regions copied count is made zero,
failed regions are processed via existing method.

For all failure cases we fallback to generic file copy range

First of all, ret < 0 is redundant.

But more importantly, why do you want to fall back to
do_splice_direct() in zonefs copy_file_range?
How does it serve your patch set or the prospect consumers
of zonefs copy_file_range?
The reason I am asking is because commit 5dae222a5ff0
("vfs: allow copy_file_range to copy across devices")
turned out to be an API mistake that was later reverted by
868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs copies")
It is always better to return EXDEV to userspace which can
always fallback to splice itself, but maybe it has something
smarter to do.
The places where it made sense for kernel to fallback to
direct splice was for network servers server-side-copy, but that
is independent of any specific filesystem copy_file_range()
implementation.
Thanks,
Amir.

At present we don't handle few case's such as IO getting split incase of
copy offload, so we wanted to fallback to existing mechanism. So went with
default operation, do_splice_direct.

For all cases ? That would be weird. What would be the point of trying to
copy again if e.g. the dest zone has gone offline or read only ?

Please check this commit message overall: the grammar and punctuation
could really be improved.

And here truncate mutex is not locked, but goto err will unlock it. This

...The locking is completely broken in this function anyway. You take the
lock, look at something, then release the lock. Then what if a write or a
trunctate comes in when the inode is not locked ? This is completely
broken. The inode should be locked with no dio pending when this function
is called. This is only to check if everything is ok. This has no business
playing with the inode and truncate locks.

That is not a "check". So having this in a function called
zonefs_copy_file_checks() is a little strange.

So you did zonefs_copy_file_checks() outside of these locks, which mean
that everything about the source and destination files may have changed.
This does not work.

This is wierd. iszie for dst will be dst_zi->i_wpoffset. So please do:
dst_zi->i_wpoffset += bytes;
zonefs_i_size_write(dst_inode, dst_zi->i_wpoffset);
> + mutex_unlock(&dst_zi->i_truncate_mutex);
And you are not taking care of the accounting for active zones here. If
the copy made the dst zone full, it is not active anymore. You need to
call zonefs_account_active();

How can you be sure that you even did an IO when you get an error ?
zonefs_issue_copy() may have failed on its kmalloc() and no IO was done.

These checks need to be done for the generic implementation too, no ? Why
would checking this automatically trigger the offload ? What if the device
does not support offloading ?

For all cases ? That would be weird. What would be the point of trying to
copy again if e.g. the dest zone has gone offline or read only ?

Acked. I do see a gap in current zonefs cfr implementation. I will drop this
implementation for next version. Once we finalize on block copy offload
implementation, will re-pick this and send with above reviews fixed.

I meant: I do not understand "cfr". I now realize that it probably means
copy-file-range ? Please be clear and do not use abbreviations.

Now that series is converging, since patch-series touches
drivers and key components in the block layer you need accompany
the patch-series with the blktests to cover the corner cases in the
drivers which supports this operations, as I mentioned this in the
call last year....
If you need any help with that feel free to send an email to linux-block
and CC me or Shinichiro (added in CC )...

Yes any help would be appreciated. I am not familiar with blktest
development/testing cycle. Do we need add blktests along with patch
series or do we need to add after patch series gets merged(to be merged)?

we have many testcases you can refer to as an example.
Your cover-letter mentions that you have tested this code, just move
all the testcases to the blktests.
More importantly for a feature like this you should be providing
outstanding testcases in your github tree when you post the
series, it should cover critical parts of the block layer and
drivers in question.
The objective here is to have blktests updated when the code
is upstream so all the distros can test the code from
upstream blktest repo. You can refer to what we have done it
for NVMeOF in-band authentication (Thanks to Hannes and Sagi
in linux-nvme email-archives.

we have many testcases you can refer to as an example.
Your cover-letter mentions that you have tested this code, just move
all the testcases to the blktests.
More importantly for a feature like this you should be providing
outstanding testcases in your github tree when you post the
series, it should cover critical parts of the block layer and
drivers in question.
The objective here is to have blktests updated when the code
is upstream so all the distros can test the code from
upstream blktest repo. You can refer to what we have done it
for NVMeOF in-band authentication (Thanks to Hannes and Sagi
in linux-nvme email-archives.
