Dear btrfs community,
My excuses for the dumps for rather old kernel (4.9.25), nevertheless I
wonder
about your opinion about the below reported kernel crashes.
As I could understand the situation (correct me if I am wrong), it
happened
that some data block became corrupted which resulted the following
kernel trace
during the boot:
kernel BUG at
/build/linux-fB36Cv/linux-4.9.25/fs/btrfs/extent_io.c:2318!
invalid opcode: 0000 [#1] SMP
Call Trace:

The problematic file turned out to be the one used by systemd-journald
/var/log/journal/c496cea41ebc4700a0dfaabf64a21be4/system.journal
which was trying to read it (or append to it) during the boot and that
was
causing the system crash (see attached bootN_dmesg.txt).
I've rebooted in safe mode and tried to copy the data from this
partition to
another location using btrfs-restore, however kernel was crashing as
well with
a bit different symphom (see attached copyN_dmesg.txt):
Call Trace:

[<d70840e4>] ? kthread+0xb4/0xd0
[<d75aae03>] ? ret_from_fork+0x1b/0x28
Just to keep away from the problem, I've removed this file and also
removed
"compress=lzo" mount option.
Are there any updates / fixes done in that area? Is lzo option safe to
use?
P.S. Perhaps relative issue is in "Warnings" section:
https://wiki.debian.org/Btrfs#Warnings /
https://www.spinics.net/lists/linux-btrfs/msg56563.html

With best regards,

It should be safe even with that kernel. I'm not sure this is
compression related. There is a corruption bug related to inline
extents and corruption that had been fairly elusive but I think it's
fixed now. I haven't run into it though.
I would say the first step no matter what if you're using an older
kernel, is to boot a current Fedora or Arch live or install media,
mount the Btrfs and try to read the problem files and see if the
problem still happens. I can't even being to estimate the tens of
thousands of line changes since kernel 4.9.
What profile are you using for this Btrfs? Is this a raid56? What do
you get for 'btrfs fi us <mountpoint>' ?

Yes, we have commits to harden lzo decompress code in v4.18:
de885e3ee281a88f52283c7e8994e762e3a5f6bd btrfs: lzo: Harden inline lzo
compressed extent decompression
314bfa473b6b6d3efe68011899bd718b349f29d7 btrfs: lzo: Add header length
check to avoid potential out-of-bounds acc
And for the root cause, it's compressed data without csum, then scrub
could make it corrupted.
It's also fixed in v4.18:
665d4953cde6d9e75c62a07ec8f4f8fd7d396ade btrfs: scrub: Don't use inode
page cache in scrub_handle_errored_block()
ac0b4145d662a3b9e34085dea460fb06ede9b69b btrfs: scrub: Don't use inode
pages for device replace

Good point Chris. Indeed booting a fresh kernel is never a problem.
Actually I forgot to mention that I've seen the same problem with
kernel 4.12.13 (attached).

It is RAID1 volume for both metadata and data, but unfortunately I
haven't recorded the actual output before the failure. The configuration
was like this:
# btrfs filesystem show /var/log
Label: none uuid: 5b45ac8e-fd8c-4759-854a-94e45069959d
Total devices 2 FS bytes used 11.13GiB
devid 3 size 50.00GiB used 14.03GiB path /dev/sda3
devid 4 size 50.00GiB used 14.03GiB path /dev/sdc1

Thanks, Qu, for this information. Actually one time I've seen the binary
crap (not zeros) in text log files (/var/log/*.log) and I was surprised
that btrfs returned me data which is corrupted instead of signalling I/O
error. Could it be because of "compressed data without csum" problem?
Thanks!

the lzo decompression harden part isn't sent to stable kernel, so you
may still hit such problem.
