From c79b411eaa7257204f89c30651c45cea22278769 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sun, 16 Dec 2018 15:55:06 -0800 Subject: crypto: skcipher - remove remnants of internal IV generators Remove dead code related to internal IV generators, which are no longer used since they've been replaced with the "seqiv" and "echainiv" templates. The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "" or "" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used.
