From cd800560cfd64f550b1a4e6b03b9441aba0b4d24 Mon Sep 17 00:00:00 2001 From: rwatson Date: Wed, 10 Mar 2004 04:56:54 +0000 Subject: Move the AH algorithm list from a static local function variable to a static const global variable in ah_core.c. This makes it more clear that this array does not require synchronization, as well as synchronizing the layout to the ESP algorithm list. This is the version of my patch that Itojun committed to the KAME tree.
