Hi,
I did some testing with the patch from
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=875733#31 on top of stretch
LXC (1:2.0.7-2+deb9u2). At first sight, it seems to work (I can start LXC with
lxc.cap.drop = sys_admin), but somehow I can't start multiple LXC correctly
anymore.
For example the sequence:
lxc-start -n test
lxc-attach -n test "echo OK"
lxc-start -n test2
lxc-attach -n test2 "echo OK"
lxc-attach -n test "echo OK"
lxc-attach: cgroups/cgfsng.c: cgfsng_attach: 1830 No such file or directory -
Failed to attach 14680 to /sys/fs/cgroup/systemd//lxc/www-1/cgroup.procs
lxc-attach: attach.c: lxc_attach: 992 Expected
to receive sequence number 0: No such file or directory.
It might be some kind of race condition because it doesn't always happen with
two containers, sometimes it's three.
Regards,
