Subject: Changing another process' UID
Date: Tue, 10 Nov 2009 10:20:13 +0100 [thread overview]
Message-ID: <20091110092013.GA575@nibiru.local> (raw)
Hi folks,
for properly porting Plan9's factotum to Linux, I need some way
to change an running process's uid/gid.
Plan9 has special devices /dev/caphash and /dev/capuse for that.
Some time ago I chose to hack up a different, a bit more generic
way: adding special new uid / gid files to the /proc entries,
so another (root) process can change the uid of an already
running process.
I suppose there's a better way via Linux's caps api, isnt it ?
thx
