From aaf66c883813f0078e3dafe7d20d1461321ac14f Mon Sep 17 00:00:00 2001 From: Mat Martineau Date: Tue, 30 Aug 2016 11:33:13 -0700 Subject: KEYS: Split role of the keyring pointer for keyring restrict functions The first argument to the restrict_link_func_t functions was a keyring pointer. These functions are called by the key subsystem with this argument set to the destination keyring, but restrict_link_by_signature expects a pointer to the relevant trusted keyring. Restrict functions may need something other than a single struct key pointer to allow or reject key linkage, so the data used to make that decision (such as the trust keyring) is moved to a new, fourth argument. The first argument is now always the destination keyring.
