3 years agodm verity: fix FEC for RS roots unaligned to block size
Milan Broz [Tue, 23 Feb 2021 20:21:21 +0000 (21:21 +0100)]
dm verity: fix FEC for RS roots unaligned to block size

Optional Forward Error Correction (FEC) code in dm-verity uses
Reed-Solomon code and should support roots from 2 to 24.

The error correction parity bytes (of roots lengths per RS block) are
stored on a separate device in sequence without any padding.

Currently, to access FEC device, the dm-verity-fec code uses dm-bufio
client with block size set to verity data block (usually 4096 or 512
bytes).

Because this block size is not divisible by some (most!) of the roots
supported lengths, data repair cannot work for partially stored parity
bytes.

This fix changes FEC device dm-bufio block size to "roots << SECTOR_SHIFT"
where we can be sure that the full parity data is always available.
(There cannot be partial FEC blocks because parity must cover whole
sectors.)

Because the optional FEC starting offset could be unaligned to this
new block size, we have to use dm_bufio_set_sector_offset() to
configure it.

The problem is easily reproduced using veritysetup, e.g. for roots=13:

  # create verity device with RS FEC
  dd if=/dev/urandom of=data.img bs=4096 count=8 status=none
  veritysetup format data.img hash.img --fec-device=fec.img --fec-roots=13 | awk '/^Root hash/{ print $3 }' >roothash

  # create an erasure that should be always repairable with this roots setting
  dd if=/dev/zero of=data.img conv=notrunc bs=1 count=8 seek=4088 status=none

  # try to read it through dm-verity
  veritysetup open data.img test hash.img --fec-device=fec.img --fec-roots=13 $(cat roothash)
  dd if=/dev/mapper/test of=/dev/null bs=4096 status=noxfer
  # wait for possible recursive recovery in kernel
  udevadm settle
  veritysetup close test

With this fix, errors are properly repaired.
  device-mapper: verity-fec: 7:1: FEC 0: corrected 8 errors
  ...

Without it, FEC code usually ends on unrecoverable failure in RS decoder:
  device-mapper: verity-fec: 7:1: FEC 0: failed to correct: -74
  ...

This problem is present in all kernels since the FEC code's
introduction (kernel 4.5).

It is thought that this problem is not visible in Android ecosystem
because it always uses a default RS roots=2.

Note that currently, no target is using dm_bufio_set_sector_offset and

When the CONFIG_RING_BUFFER_VALIDATE_TIME_DELTAS is enabled, and the time
stamps are detected as not being valid, it reports information about the
write stamp, but does not show the before_stamp which is still useful
information. Also, it should give a warning once, such that tests detect
this happening.

3 years agoring-buffer: Force before_stamp and write_stamp to be different on discard

ring-buffer: Force before_stamp and write_stamp to be different on discard

Part of the logic of the new time stamp code depends on the before_stamp and
the write_stamp to be different if the write_stamp does not match the last
event on the buffer, as it will be used to calculate the delta of the next
event written on the buffer.

The discard logic depends on this, as the next event to come in needs to
inject a full timestamp as it can not rely on the last event timestamp in
the buffer because it is unknown due to events after it being discarded. But
by changing the write_stamp back to the time before it, it forces the next
event to use a full time stamp, instead of relying on it.

The issue came when a full time stamp was used for the event, and
rb_time_delta() returns zero in that case. The update to the write_stamp
(which subtracts delta) made it not change. Then when the event is removed
from the buffer, because the before_stamp and write_stamp still match, the
next event written would calculate its delta from the write_stamp, but that
would be wrong as the write_stamp is of the time of the event that was
discarded.

In the case that the delta change being made to write_stamp is zero, set the
before_stamp to zero as well, and this will force the next event to inject a
full timestamp and not use the current write_stamp.
