Bug description:
SRU Justification:
[Impact]
* Parity page in btrfs raid56 is incorrectly unmapped, allowing to
easily trigger a reference counter bug on i386 causing a kernel panic
* The fix unmaps the right rbio pages and adds the proper kunmap()
call for the parity page
[Test Case]
* create a raid5 btrfs filesystem:
# mkfs.btrfs -m raid5 -d raid5 /dev/sdb /dev/sdc /dev/sdd /dev/sde
* mount it:
# mount /dev/sdb /mnt
* run btrfs scrub in a loop:
# while :; do btrfs scrub start -BR /mnt; done
[Fix]
*
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3897b6f0a859288c22fb793fad11ec2327e60fcd
kunmap(p_page) was completely left out, so we never
did an unmap for the p_page and the loop unmapping the rbio page was
iterating over the wrong number of stripes: unmapping should be done
with nr_data instead of rbio->real_stripes.
[Regression Potential]
* This is an upstream fix, tested on the affected platform. The bug
is affecting only btrfs raid5/6 users on architectures where kunamp()
is not a no-op (like i386). It is also a very small patch, so backport
changes are minimal.
[Original bug report]
This issue was not spotted on AMD64
Reproduce rate: 100%
The following command is the key to trigger this:
btrfs scrub start -BR $MNT
Steps:
# (Install necessary packages)
# git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests
# TMP=/tmp/tmp MNT=/tmp/mnt
# mkdir -p $TMP; mkdir -p $MNT
# cd autotest-client-tests/ubuntu_btrfs_kernel_fixes
# TMP=/tmp/tmp MNT=/tmp/mnt ./3b080b2564287be91605bfd1d5ee985696e61d3c.sh
