Source: linux-latest Version: 86 Severity: normal systemd complains in syslog about Debian kernels not supporting BPF/cgroup firewalling:
systemd[1]: File /lib/systemd/system/systemd-udevd.service:32 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling. systemd[1]: File /lib/systemd/system/systemd-logind.service:35 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling. systemd[1]: File /lib/systemd/system/systemd-journald.service:33 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling. According to this upstream bug: https://github.com/systemd/systemd/issues/7188 it's just a matter of adding the following to the kernel config: CONFIG_BPF_SYSCALL=y Francois -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.13.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_CA.UTF-8, LC_CTYPE=fr_CA.UTF-8 (charmap=UTF-8), LANGUAGE=fr_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
