From 4e54f08543d05e519e601368571cc3787fefae96 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 29 Jun 2006 02:24:28 -0700 Subject: [PATCH] Keys: Allow in-kernel key requestor to pass auxiliary data to upcaller The proposed NFS key type uses its own method of passing key requests to userspace (upcalling) rather than invoking /sbin/request-key. This is because the responsible userspace daemon should already be running and will be contacted through rpc_pipefs. This patch permits the NFS filesystem to pass auxiliary data to the upcall operation (struct key_type::request_key) so that the upcaller can use a pre-existing communications channel more easily.
