Bug#878965: systemd spam syslog with Detaching egress BPF program from cgroup failed: Invalid argument

[Boris Shtrasman]

Package: systemd
Version: 235-2
Severity: normal
Tags: upstream

Dear Maintainer,

Systemd spams my syslog with systemd[1]: Detaching egress BPF program
from cgroup failed: Invalid argument after boot and reloads.

systemd[1]: Detaching egress BPF program from cgroup failed: Invalid argument
systemd[1]: Attaching egress BPF program to cgroup /sys/fs/cgroup/unified/system.slice/systemd-udevd.service failed: Invalid argument
systemd[1]: Detaching egress BPF program from cgroup failed: Invalid argument

most the syslog is filled with that message:

grep "gress BPF program"  /var/log/syslog | wc -l:
1296

grep ""  /var/log/syslog | wc -l
1508

The kernel BPF settings (standard kernel from debian) :

grep BPF /boot/config-4.13.0-1-amd64
# CONFIG_CGROUP_BPF is not set
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
CONFIG_NETFILTER_XT_MATCH_BPF=m
CONFIG_NET_CLS_BPF=m
CONFIG_NET_ACT_BPF=m
CONFIG_BPF_JIT=y
CONFIG_LWTUNNEL_BPF=y
CONFIG_HAVE_EBPF_JIT=y
CONFIG_BPF_EVENTS=y
CONFIG_TEST_BPF=m
