#81785 — Bug#1063422: linux-image-6.1.0-18-amd64: F2FS rw mount at boot fails with "invalid zstd compress level: 6"

Package: src:linux
Version: 6.1.76-1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After upgrade to linux-image-6.1.0-18-amd64 6.1.76-1 F2FS filesystem
fails to mount rw.  Message in the boot journal:

  kernel: F2FS-fs (nvme0n1p6): invalid zstd compress level: 6

There was recently an f2fs patch to the 6.1 kernel tree which might be
related: https://www.spinics.net/lists/stable-commits/msg329957.html

Was able to recover the system by doing:

sudo mount -o remount,rw,relatime,lazytime,background_gc=on,discard,no_heap,user_xattr,inline_xattr,acl,inline_data,inline_dentry,extent_cache,mode=adaptive,active_logs=6,alloc_mode=default,checkpoint_merge,fsync_mode=posix,compress_algorithm=lz4,compress_log_size=2,compress_mode=fs,atgc,discard_unit=block,memory=normal /dev/nvme0n1p6 /

under the running bad 6.1.0-18-amd64 kernel, then editing
/etc/default/grub:

  GRUB_DEFAULT="Advanced options for Debian GNU/Linux>Debian GNU/Linux, with Linux 6.1.0-17-amd64"

and running 'update-grub' and rebooting to boot the 6.1.0-17-amd64
kernel.

Thanks for the report. Can you please report your finding upstream and
keep this downstream report in the loop as well please?

#81797 — Bug#1063422: [regression 6.1.y] f2fs: invalid zstd compress level: 6

Hi Jaegeuk Kim, Chao Yu,

In Debian the following regression was reported after a Dhya updated
to 6.1.76:

The issue is easily reproducible by:

# dd if=/dev/zero of=test.img count=100 bs=1M
# mkfs.f2fs -f -O compression,extra_attr ./test.img
# mount -t f2fs -o compress_algorithm=zstd:6,compress_chksum,atgc,gc_merge,lazytime ./test.img /mnt

resulting in

[   60.789982] F2FS-fs (loop0): invalid zstd compress level: 6

A bugzilla report has been submitted in
https://bugzilla.kernel.org/show_bug.cgi?id=218471

Confirmed that this fixes the reported issue as it was reported to us
in Debian in https://bugs.debian.org/1063422 . Thanks a lot!
(note just tested with the first commit as it landed in 6.1.78 to
confirm the immediate regression).
