[PATCH 1/6] f2fs: rework write preallocations

[PATCH 1/6] f2fs: rework write preallocations

[Jaegeuk Kim]

From: Eric Biggers <ebiggers@google.com>

f2fs_write_begin() assumes that all blocks were preallocated by
default unless FI_NO_PREALLOC is explicitly set.  This invites data
corruption, as there are cases in which not all blocks are preallocated.
Commit 47501f87c61a ("f2fs: preallocate DIO blocks when forcing
buffered_io") fixed one case, but there are others remaining.

Fix up this logic by replacing this flag with FI_PREALLOCATED_ALL, which
only gets set if all blocks for the current write were preallocated.

Also clean up f2fs_preallocate_blocks(), move it to file.c, and make it
handle some of the logic that was previously in write_iter() directly.

Jaegeuk:
DIO to holes are turning into buffered IO in f2fs_direct_IO, so we should
not preallocate blocks.

[PATCH 2/6] f2fs: do not expose unwritten blocks to user by DIO

[Jaegeuk Kim]

DIO preallocates physical blocks before writing data, but if an error occurrs
or power-cut happens, we can see block contents from the disk. This patch tries
to fix it by 1) turning to buffered writes for DIO into holes, 2) truncating
unwritten blocks from error or power-cut.

[PATCH 4/6] f2fs: fix the f2fs_file_write_iter tracepoint

[Jaegeuk Kim]

From: Eric Biggers <ebiggers@google.com>

Pass in the original position and count rather than the position and
count that were updated by the write.  Also use the correct types for
all arguments, in particular the file offset which was being truncated
to 32 bits on 32-bit platforms.

[PATCH 5/6] f2fs: implement iomap operations

[Jaegeuk Kim]

From: Eric Biggers <ebiggers@google.com>

Implement 'struct iomap_ops' for f2fs, in preparation for making f2fs
use iomap for direct I/O.

Note that this may be used for other things besides direct I/O in the
future; however, for now I've only tested it for direct I/O.

[PATCH 6/6] f2fs: use iomap for direct I/O

[Jaegeuk Kim]

From: Eric Biggers <ebiggers@google.com>

Make f2fs_file_read_iter() and f2fs_file_write_iter() use the iomap
direct I/O implementation instead of the fs/direct-io.c one.

The iomap implementation is more efficient, and it also avoids the need
to add new features and optimizations to the old implementation.

This new implementation also eliminates the need for f2fs to hook bio
submission and completion and to allocate memory per-bio.  This is
because it's possible to correctly update f2fs's in-flight DIO counters
using __iomap_dio_rw() in combination with an implementation of
iomap_dio_ops::end_io() (as suggested by Christoph Hellwig).

When possible, this new implementation preserves existing f2fs behavior
such as the conditions for falling back to buffered I/O.

This patch has been tested with xfstests by running 'gce-xfstests -c
f2fs -g auto -X generic/017' with and without this patch; no regressions
were seen.  (Some tests fail both before and after.  generic/017 hangs
both before and after, so it had to be excluded.)

[-- Attachment #1: Type: text/plain, Size: 112070 bytes --]



Greeting,

FYI, we noticed a -35.8% regression of aim7.jobs-per-min due to commit:


commit: e029ce24606afa6d6f2955f335eacd9ece4b1aa5 ("[PATCH 2/6] f2fs: do not expose unwritten blocks to user by DIO")
url: https://github.com/0day-ci/linux/commits/Jaegeuk-Kim/f2fs-rework-write-preallocations/20211117-054644
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 8ab774587903771821b59471cc723bba6d893942
patch link: https://lore.kernel.org/lkml/20211116214510.2934905-2-jaegeuk@kernel.org

in testcase: aim7
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:

	disk: 1BRD_48G
	fs: f2fs
	test: disk_cp
	load: 3000
	cpufreq_governor: performance

If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@intel.com>


Details are as below:
-------------------------------------------------------------------------------------------------->


To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.

How about this case:

- touch file
- DIO write [0, 8kb] to file
  - preallocate 2 physical blocks
  - set FADVISE_TRUNC_BIT
  - SPO
- BUFIO write [0, 4kb] to file
  - file_dont_truncate -- it leaks unwritten [4kb, 8kb] to user after
truncating file to 8kb

Thanks,

Are you talking about the check for !f2fs_is_multi_device()?  It could go in
either location, but I think it makes the most sense to have it right before the
line that uses 'inode->i_sb->s_bdev', since that is the place which makes the
assumption that the filesystem has only one block device.

Wait, it supports DIO in multi-device image after commit 	71f2c8206202 
("f2fs: multidevice: support direct IO"), how about
checking with f2fs_allow_multi_device_dio()?

Thanks,

Okay, that was not the case when I sent this patch originally.  We'll need to
update this to support multiple devices.

I guess so, but why doesn't f2fs_map_blocks() just always set m_bdev to the
correct block device?  What is the point of m_multidev_dio?

It seems we can simply assign iomap->bdev = map.m_bdev, and remove
map->m_multidev_dio.

Ok, it was used in previous get_block flow, but I think it'd be worth to keep it
to show by f2fs_map_blocks tracepoint.

- BUFIO write [0, 4kb] to file
  - file_dont_truncate()
i_size should be 4kb, w/ FADVISE_TRUNC_BIT

- setattr 8kb
i_size should be 8kb, last [4kb, 8kb] is unwritten

Yes, it was added for that.

How about this to truncate it in f2fs_iget() inestead of f2fs_setattr()?

DIO preallocates physical blocks before writing data, but if an error occurrs
or power-cut happens, we can see block contents from the disk. This patch tries
to fix it by 1) turning to buffered writes for DIO into holes, 2) truncating
unwritten blocks from error or power-cut.

[PATCH 6/6] f2fs: use iomap for direct I/O

[Jaegeuk Kim]

From: Eric Biggers <ebiggers@google.com>

Make f2fs_file_read_iter() and f2fs_file_write_iter() use the iomap
direct I/O implementation instead of the fs/direct-io.c one.

The iomap implementation is more efficient, and it also avoids the need
to add new features and optimizations to the old implementation.

This new implementation also eliminates the need for f2fs to hook bio
submission and completion and to allocate memory per-bio.  This is
because it's possible to correctly update f2fs's in-flight DIO counters
using __iomap_dio_rw() in combination with an implementation of
iomap_dio_ops::end_io() (as suggested by Christoph Hellwig).

When possible, this new implementation preserves existing f2fs behavior
such as the conditions for falling back to buffered I/O.

This patch has been tested with xfstests by running 'gce-xfstests -c
f2fs -g auto -X generic/017' with and without this patch; no regressions
were seen.  (Some tests fail both before and after.  generic/017 hangs
both before and after, so it had to be excluded.)
