[DESTRUCTIVE RMW]
Btrfs (and generic) RAID56 is always vulnerable against destructive RMW.

Such destructive RMW can happen when one of the data stripe is
corrupted, then a sub-stripe write into other data stripes happens, like
the following:


  Disk 1: data 1 |0x000000000000| <- Corrupted
  Disk 2: data 2 |0x000000000000|
  Disk 2: parity |0xffffffffffff|

In above case, if we write data into disk 2, we will got something like
this:

  Disk 1: data 1 |0x000000000000| <- Corrupted
  Disk 2: data 2 |0x000000000000| <- New '0x00' writes
  Disk 2: parity |0x000000000000| <- New Parity.

Since the new parity is calculated using the new writes and the
corrupted data, we lost the chance to recovery data stripe 1, and that
corruption will forever be there.

[SOLUTION]
This series will close the destructive RMW problem for RAID5 data
profiles by:

- Read the full stripe before doing sub-stripe writes.

- Also fetch the data csum for the data stripes:

- Verify every data sector against their data checksum

  Now even with above corrupted data, we know there are some data csum
  mismatch, we will have an error bitmap to record such mismatches.
  We treat read error (like missing device) and data csum mismatch the
  same.

  If there is no csum (NODATASUM or metadata), we just trust the data
  unconditionally.

  So we will have an error bitmap for above corrupted case like this:

  Disk 1: data 1: |XXXXXXX|
  Disk 2: data 2: |       |

- Rebuild just as usual
  Since data 1 has all its sectors marked error in the error bitmap,
  we rebuild the sectors of data stripe 1.

- Verify the repaired sectors against their csum
  If csum matches, we can continue.
  Or we error out.

- Continue the RMW cycle using the repaired sectors
  Now we have correct data and will re-calculate the correct parity.

[TODO]
- Iterate all RAID6 combinations
  Currently we don't try all combinations of RAID6 during the repair.
  Thus for RAID6 we treat it just like RAID5 in RMW.

  Currently the RAID6 recovery combination is only exhausted during
  recovery path, relying on the caller the increase the mirror number.

  Can be implemented later for RMW path.

- Write back the repaired sectors
  Currently we don't write back the repaired sectors, thus if we read
  the corrupted sectors, we rely on the recover path, and since the new
  parity is calculated using the recovered sectors, we can get the
  correct data without any problem.

  But if we write back the repaired sectors during RMW, we can save the
  reader some time without going into recovery path at all.

  This is just a performance optimization, thus I believe it can be
  implemented later.

Qu Wenruo (5):
  btrfs: use btrfs_dev_name() helper to handle missing devices better
  btrfs: refactor btrfs_lookup_csums_range()
  btrfs: introduce a bitmap based csum range search function
  btrfs: raid56: prepare data checksums for later RMW data csum 
    verification
  btrfs: raid56: do data csum verification during RMW cycle

[BUG]
If dev-replace failed to re-construct its data/metadata, the kernel
message would be incorrect for the missing device:

 BTRFS info (device dm-1): dev_replace from <missing disk> (devid 2) to /dev/mapper/test-scratch2 started
 BTRFS error (device dm-1): failed to rebuild valid logical 38862848 for dev (efault)

Note the above "dev (efault)" of the second line.
While the first line is properly reporting "<missing disk>".

[CAUSE]
Although dev-replace is using btrfs_dev_name(), the heavy lifting work
is still done by scrub (scrub is reused by both dev-replace and regular
scrub).

Unfortunately scrub code never uses btrfs_dev_name() helper, as it's
only declared locally inside dev-replace.c.

[FIX]
Fix the output by:

- Move the btrfs_dev_name() helper to volumes.h

- Use btrfs_dev_name() to replace open-coded rcu_str_defref() calls
  Only zoned code is not touched, as I'm not familiar with degraded
  zoned code.

Now the output looks pretty sane:

 BTRFS info (device dm-1): dev_replace from <missing disk> (devid 2) to /dev/mapper/test-scratch2 started
 BTRFS error (device dm-1): failed to rebuild valid logical 38862848 for dev <missing disk>

* [PATCH 2/5] btrfs: refactor btrfs_lookup_csums_range()

  To: linux-btrfs

The refactor involves the following parts:

- Introduce bytes_to_csum_size() and csum_size_to_bytes() helpers
  As we have quite some open-coded calculation, some of them are even
  split into two assignments just to fit 80 chars limit.

- Remove the @csum_size parameter from max_ordered_sum_bytes()
  Csum size can be fetched from @fs_info.
  And we will use the csum_size_to_bytes() helper anyway.

- Add a comment explaining how we handle the first search result

- Use newly introduced helpers to cleanup btrfs_lookup_csums_range()

- Move variables declaration to the minimal scope

- Never mix number of sectors with bytes
  There are several locations doing things like:

 			size = min_t(size_t, csum_end - start,
				     max_ordered_sum_bytes(fs_info));
			...
			size >>= fs_info->sectorsize_bits

  Or

			offset = (start - key.offset) >> fs_info->sectorsize_bits;
			offset *= csum_size;

  Make sure those variables can only represent BYTES inside the
  function, by using the above bytes_to_csum_size() helpers.

  To: linux-btrfs

Although we have an existing function, btrfs_lookup_csums_range(), to
find all data checksum for a range, it's based on a btrfs_ordered_sum
list.

For the incoming RAID56 data checksum verification at RMW time, we don't
want to waste time memory allocating the temporary memory.

So this patch will introduce a new helper, btrfs_lookup_csums_bitmap().

The new helper will use bitmap based result, which will be a perfect fit
for later RAID56 usage.

This is for later data verification at RMW time.

This patch will try to allocate the needed memory for a locked rbio if
the rbio is for data exclusively (we don't want to handle mixed bg yet).

And the memory will be released when the rbio is finished.

[BUG]
For the following small script, btrfs will be unable to recover the
content of file1:

  mkfs.btrfs -f -m raid1 -d raid5 -b 1G $dev1 $dev2 $dev3

  mount $dev1 $mnt
  xfs_io -f -c "pwrite -S 0xff 0 64k" -c sync $mnt/file1
  md5sum $mnt/file1
  umount $mnt

  # Corrupt the above 64K data stripe.
  xfs_io -f -c "pwrite -S 0x00 323026944 64K" -c sync $dev3
  mount $dev1 $mnt

  # Write a new 64K, which should be in the other data stripe
  # And this is a sub-stripe write, which will cause RMW
  xfs_io -f -c "pwrite 0 64k" -c sync $mnt/file2
  md5sum $mnt/file1
  umount $mnt

Above md5sum would fail.

[CAUSE]
There is a long existing problem for raid56 (not limited to btrfs
raid56) that, if we already have some corrupted on-disk data, and then
trigger a sub-stripe write (which needs RMW cycle), it can cause further
damage into P/Q stripe.

  Disk 1: data 1 |0x000000000000| <- Corrupted
  Disk 2: data 2 |0x000000000000|
  Disk 2: parity |0xffffffffffff|

In above case, data 1 is already corrupted, the original data should be
64KiB of 0xff.

At this stage, if we read data 1, and it has data checksum, we can still
recover going the regular RAID56 recovery path.

But if now we decide to write some data into data 2, then we need to go
RMW.
Just say we want to write 64KiB of '0x00' into data 2, then we read the
on-disk data of data 1, calculate the new parity, resulting the
following layout:

  Disk 1: data 1 |0x000000000000| <- Corrupted
  Disk 2: data 2 |0x000000000000| <- New '0x00' writes
  Disk 2: parity |0x000000000000| <- New Parity.

But the new parity is calculated using the *corrupted* data 1, we can
no longer recover the correct data of data1.
Thus the corruption is forever there.

[FIX]
To solve above problem, this patch will do a full stripe data checksum
verification at RMW time.

This involves the following changes:

- Always read the full stripe (including data/P/Q) when doing RMW
  Before we only read the missing data sectors, but since we may do a
  data csum verification and recovery, we need to read everything out.

  Please note that, if we have a cached rbio, we don't need to read
  anything, and can treat it the same as full stripe write.

  As only stripe with all its csum matches can be cached.

- Verifup the data csum during read.
  The target is only the rbio stripe sectors, and only if the rbio
  already has csum_buf/csum_bitmap filled.

  And sectors which can not pass csum verification will has its bit
  set in error_bitmap.

- Always call recovery_sectors() after we read out all the sectors
  Since error_bitmap will be updated during read, recover_sectors()
  can easily find out all the bad sectors and try to recover (if still
  under tolerance).

  And since recovery_sectors() is already migrated to use error_bitmap,
  it can skip vertical stripes which don't have any error.

- Verify the repaired sectors against its csum in recover_vertical()

- Rename rmw_read_and_wait() to rmw_read_wait_recover()
  Since we will always recover the sectors, the old name is no longer
  accurate.

  Furthermore since recovery is already done in rmw_read_wait_recover(),
  we no longer needs to call recovery_sectors() inside rmw_rbio().

Obviously this will have a performance impact, as we are doing more
works during RMW cycle:

- Fetch the data checksum
- Do checksum verification for all data stripes
- Do checksum verification again after repair

But for full stripe write or cached rbio we won't have the overhead all,
thus for fully optimized RAID56 workload (always full stripe write),
there should be no extra overhead.

To me, the extra overhead looks reasonable, as data consistency is way
more important than performance.

Please ignore this one, this patch has already been sent as an 
independent patch.

The remaining 4 are the main patches.

Because we are returning a static char*, should we mark the return
values as "const char*" ?

static inline const char* btrfs_dev_name(struct btrfs_device *device)

Right, that would be more accurate.

Not sure if David can fold this change during merging.

Even with the todo and potential performance drop due to mandatory
stripe caching I think this is worth merging at this point, so patches
are in misc-next now.

Regarding the perf drop, I'll try to get some results besides functional
testing but if anybody with a decent setup for raid5 can do some
destructive tests it would be most welcome.

Fallback plan is to revert the last patch if it turns out to be too
problematic.

If you're concerned about the fallback plan, I'd say we need to at least 
drop the last two patches.

Sure, dropping the last one will remove the verification and the extra 
reads, but unfortunately we will still fetch the csum for RMW cycles.
Although the csum fetch would at most cost 2 leaves, the cost is still 
there.

Thus if needed, I can do more refactoring of the series, to separate the 
final patch.
Although I hope we don't need to go that path.

Thanks,
Qu
