Package: lxcfs
Version: 4.0.7-1
Using this package version on a Raspberry PI 4 with the host being arm64
LXC containers (arm32 and arm64) entries in /proc are not usable/not
being updated_
The following entries are affected (ls -lisa output):
102005 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 cpuinfo
102006 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 diskstats
102007 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 loadavg
102008 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 meminfo
102009 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 stat
102010 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 swaps
102011 4 -r--r--r-- 1 nobody nogroup 4096 28. Dez 15:10 uptime
This also leads to programs like pkill and pgrep to not work properly
and was the reason I discovered the problem:
$ pgrep test
pgrep: uptime
$
Using the following command inside the container one is able to get the
/proc entries working again and this does not seem to have any side effects:
/usr/bin/find /proc/ -maxdepth 1 -size 4096c -exec /bin/umount {} \;
According to this discussion https://github.com/lxc/lxcfs/issues/553 the
bug was just recently fixed here https://github.com/lxc/lxcfs/pull/567.
I am using Raspbian Debian Bullseye 11.2 Linux version 5.15.76-v8+

This can be closed as the original package does behave as it should.
The process of creating the root fs, where /var/lib/lxcfs resided
resulted in static files being placed their overlaying the /proc in the
containers. Deleting the static files made the containers work as expected.
