Eelco Dolstra	765bdfe542	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave ... mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure.	2006-11-30 19:54:43 +00:00
Eelco Dolstra	40b3f64b55	* Skeleton of the privileged worker program. ... * Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.	2006-11-30 19:19:59 +00:00
