Package: nftables
Version: 0.9.0-2
Severity: important
Dear Maintainer
I performed a test upgrade of a cloud VM running Debian Stretch
to buster. After the upgrade the VM does not boot any longer if
the `nftables.service` is enabled and the 4.19 kernel is used,
because a kernel assertion is violated.
The old 4.9 kernel from stretch works fine. I was able to disable the
`nftables.service` there. Afterwards the 4.19 kernel boots fine.
If I manually start the `nftables.service` the process will
segfault and the same kernel assertion will be logged. I was able
to reduce my nftables.conf to the attached one, it still triggers
the assertion.
It looks like (one of) the two `flow table` lines are at fault,
but I am not able to confirm this for sure, because the assertion
is not 100% reliably triggered.
If I try to load the ruleset after the assertion is triggered once
the `nft` process will hang in uninterruptable sleep (state `D`), I
assume, because the reponsible kernel thread died.
Note that the kernel stack has an `apparmor` frame, but the only
apparmor package installed is `libapparmor1`.
Because it might possibly be relevant (out of tree kernel module):
The cloud VM is running with root on ZFS with the buster DKMS
packages.
I am attaching:
lsmod : The output of lsmod.
journalctl_-b_-t_kernel: The log of the assertion.
strace : The end of the output of `strace`, right
before the segfault.
