How do you write SELinux policies to allow reading only certain files in /proc, where process IDs are not known ahead? I ended up writing my own FUSE-based /proc emulation. The facilities are there, but it feels like writing your own OS.
replyWhat kind of use-case do you have for that? I suppose whatever it is, you could also e.g. write a privileged service that checks those files with whatever security policy you need. Your client wouldn't have direct access to /proc.
replyAnother option may be to setup a container or PID namespace and give your tool direct access to that /proc.
That's an interesting limit from having to work with such directories.
