From 17c2a42a24e1e8dd6aa7cea4f84e034ab1bfff31 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 17 Oct 2007 21:33:12 -0700 Subject: [IPSEC]: Store afinfo pointer in xfrm_mode It is convenient to have a pointer from xfrm_state to address-specific functions such as the output function for a family. Currently the address-specific policy code calls out to the xfrm state code to get those pointers when we could get it in an easier way via the state itself. This patch adds an xfrm_state_afinfo to xfrm_mode (since they're address-specific) and changes the policy code to use it. I've also added an owner field to do reference counting on the module providing the afinfo even though it isn't strictly necessary today since IPv6 can't be unloaded yet.
