System information

Type Version/Name
Distribution Name ubuntu
Distribution Version 22.04
Kernel Version 5.15.0-91-generic
Architecture x86_64
OpenZFS Version 2.2.2 + commit 55b764e + block cloning enabled

Describe the problem you're observing

The system might crash (likelihood 50%) while building a container when block cloning is enabled. Logs are provided hereafter
Building the container is ok when block cloning is disabled.

Describe how to reproduce the problem

This laptop is running a zfs-on-root ubuntu 22.04. Only 1 SSD device in the pool.
The rootfs dataset and the home dataset are encrytpted (zfs native).

I am using buildah & podman with following configuration:

olivier@bison:~$ cat .config/containers/storage.conf 
[storage]
driver = "overlay"
rootless_storage_path = "/eXchange/olivier/.local/share/containers/storage"
[storage.options]
mount_program = "/usr/bin/fuse-overlayfs"

I tried different locations with the rootless_storage_path, to see if encryption was part of the problem and it seems to be irrelevant.

To reproduce the issue (at least on my laptop):

olivier@bison:~$ sudo bash -c "echo 1 >>  /sys/module/zfs/parameters/zfs_bclone_enabled"
olivier@bison:~$ git clone git@github.com:zbm-dev/zfsbootmenu.git
olivier@bison:~$ cd zfsbootmenu/
olivier@bison:~/zfsbootmenu$ ./releng/docker/image-build.sh -k 6.1 zbm-builder:test

When the she system hangs, it would happen during the zfs dkms build (how ironic it is !):

I wonder if this issue may be resolved by #15656 . I haven't see it myself-, but I suspect the bug it fixes may cause the NULL pointer de-reference in dbuf_write() just as shown here.

I will test with #15656 and share the result.

@ofthesun9 I've merged #15656 in to the master branch. If it's easier you can test directly with that branch.

I have applied Add VERIFY0P() and ASSERT0P() macros and your #15656 in a 2.2.2 branch and i cannot reproduce the issue after 10 builds in a row. It sounds like @amotin fixed the issue indeed !

Great. Then let's close this issue out. We'll include all of the recent block clones fixes in 2.2.3.
