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

CONFIG_BPF_SYSCALL=y is already set since 4.2.5-1. Should that be
CONFIG_CGROUP_BPF in addition (cf. #872560).

In reply to#59335
The systemd documentation at
https://github.com/systemd/systemd/blob/master/README
states:

Required for IPAddressDeny= and IPAddressAllow= in resource control unit 
settings:
CONFIG_CGROUP_BPF

Please, enable this in the kernel configuration.

Best regards
