Message-ID: <20080502121641.GB7997@nibiru.local> Date: Fri, 2 May 2008 14:16:42 +0200 From: Enrico Weigelt <weigelt@...ux.de> To: linux kernel list <linux-kernel@...r.kernel.org> Subject: API for changing UIDs of other processes Hi folks, I'd like to build some authentication daemon which alters the privileges of another process (like factotum does on plan9). But I couldn't find any interface for that (setuid() and friends only operate on the current process). So I'm now going to create my own interface. As a little learning example I just added a few files to the per-pid dirs: uid, euid, suid, fsuid. This was trivial :) Now I'd like to add an write capability to these files: simply writing another number changes the (|s|fs)uid. But this doesnt seem that trivial. Perhaps someone could give me some advice ? cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
