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. dpkg -l |egrep 'nftables|zfs-|linux-image|apparmor': ii libapparmor1:amd64 2.13.2-10 amd64 changehat AppArmor library ii libnftables0:amd64 0.9.0-2 amd64 Netfilter nftables high level userspace API library ii libnftnl11:amd64 1.1.2-2 amd64 Netfilter nftables userspace API library ii libnftnl4:amd64 1.0.7-1 amd64 Netfilter nftables userspace API library ii linux-image-4.19.0-5-amd64 4.19.37-5 amd64 Linux 4.19 for 64-bit PCs (signed) ii linux-image-4.9.0-8-amd64 4.9.144-3.1 amd64 Linux 4.9 for 64-bit PCs ii linux-image-4.9.0-9-amd64 4.9.168-1+deb9u3 amd64 Linux 4.9 for 64-bit PCs ii linux-image-amd64 4.19+105 amd64 Linux for 64-bit PCs (meta-package) ii nftables 0.9.0-2 amd64 Program to control packet filtering rules by Netfilter project ii zfs-dkms 0.7.12-2+deb10u1 all OpenZFS filesystem kernel modules for Linux ii zfs-initramfs 0.7.12-2+deb10u1 all OpenZFS root filesystem capabilities for Linux - initramfs ii zfs-zed 0.7.12-2+deb10u1 amd64 OpenZFS Event Daemon -- System Information: Debian Release: 10.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/2 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_DIE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages nftables depends on: ii dpkg 1.19.7 ii libc6 2.28-10 ii libgmp10 2:6.1.2+dfsg-4 ii libjansson4 2.12-1 ii libnftables0 0.9.0-2 ii libreadline7 7.0-5 nftables recommends no packages. nftables suggests no packages. -- Configuration Files: /etc/nftables.conf changed: flush ruleset table inet filter { chain input { type filter hook input priority 0; # accept any localhost traffic iif lo accept # accept traffic originated from us ct state established,related accept # Drop invalid ct state invalid drop tcp dport { 22 } ct state new flow table ssh-limit4 { ip saddr limit rate 10/minute } accept tcp dport { 22 } ct state new flow table ssh-limit6 { ip6 saddr limit rate 10/minute } accept } } -- no debconf information
