From: Herbert Xu Date: Tue, 27 Nov 2007 13:33:24 +0000 (+0800) Subject: [CRYPTO] skcipher: Added geniv field X-Git-Tag: v2.6.25-rc1~1242^2~42 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=23508e11ab3bb405dca66bf4d77e488bf2b07b0c;p=linux-2.6 [CRYPTO] skcipher: Added geniv field This patch introduces the geniv field which indicates the default IV generator for each algorithm. It should point to a string that is not freed as long as the algorithm is registered.
