[lxc-devel] [PATCH] procfs in containers based on fuse

[Zhou Kang(研究院)]

Hi
This patch is for procfs in per container. It is based on Daniel Lezcano’s code which use fsue. ( https://github.com/hallyn/procfs ), but we made the following improvements.

l  The fuse_main is started by lxc_start, so it’s easier to manage the container

l  We mount the /proc path in /tmp instead of rootfs, the path is uniq.

l  We rewrite the following files: meminfo, stat, cpuinfo, sysrq-trigger. The command ‘top’ can show the right info in the container.

l  /proc/ sysrq-trigger is unwritable.

We tested this patch on hundreds of containers for a long time, it had worked very well.
