Hi, I am trying to add lxc.shmmax as a configuration option for lxc-execute, so the container would have desired shmmax setting. I run lxc-execute as a regular user and setuid root. When trying to open /proc/sys/kernel/shmmax for write in lxc_setup(), I got "permission denied". I checked that all the capabilities are up in PERMITTED and EFFECTIVE set. Does anyone know the reason for not being able to write to /proc/sys/kernel/shmmax? I can work around this problem by setting the euid to 0 before the open/write, but I would like to understand the permission issue.
Thanks.
