Bug#986905: systemd armhf: Attaching egress BPF program to cgroup failed

[Ryutaroh Matsumoto]

My reports have been wrong.
This reported symptom is also observed with Debian amd64&arm64, outside of a VM,
with task-xfce-desktop installed and
DefaultIPAccounting=yes in /etc/systemd/user.conf.

In
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=986905#5
all the error messages are from systemd user instance (whose PID != 1),
and the error is "Invalid argument".

But on linux-image-armmp-lpae running a barebone hardware (my RPi4B 8GB),
the symptom has difference appearance:
The systemd system instance (PID==1) also gives
"Attaching egress BPF program to cgroup failed",
and its reason is "Cannot allocate memory". (What is it???)

A full output of "journalctl -b -g BPF" on barebone hardware is as below,
which cannot be reproduced in a VM (afaik):
