[Pkg-zfsonlinux-devel] Bug#1063497: zfs-dkms: Data loss bug in version in bookworm

[John Goerzen]

Package: zfs-dkms
Version: 2.1.11-1
Severity: critical
Tags: patch upstream
Justification: causes serious data loss

Hello ZFS maintainers!  Thank you for maintaining this for Debian.

In the release notes for ZFS 2.1.14 at
https://github.com/openzfs/zfs/releases/tag/zfs-2.1.14, it states:

"This release contains an important fix for a data corruption bug. Full details
are in the issue (#15526) and bug fix (#15571). There's also a developer's bug
summary that gives a good overview...  This bug is very hard to hit, and really
only came to light due to changes in cp in coreutils 9.x. It's extremely
unlikely that the bug was ever hit on EL7 or EL8 when running cp since they all
use coreutils 8.x which performs file copies differently."

I'll note that bookworm contains coreutils 9.x.

Two options would exist to get this into stable-proposed-updates:

1) Backport the patch (linked to from the release notes) onto 2.1.14 (likely
easy),

or

2) Upgrade stable to 2.1.14.

If you would like my assistance with either of these steps, I'm available to help.

John
