From b9fffa3877a3ebbe0a5ad5a247358e2f7df15b24 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 7 Mar 2011 15:05:59 +0000 Subject: KEYS: Add a key type op to permit the key description to be vetted Add a key type operation to permit the key type to vet the description of a new key that key_alloc() is about to allocate. The operation may reject the description if it wishes with an error of its choosing. If it does this, the key will not be allocated.
