From 578c60fbeb913e0f2aa49f37a04d475b615c8a8d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 25 Jan 2016 17:51:21 +0100 Subject: crypto: ghash,poly1305 - select CRYPTO_HASH where needed The ghash and poly1305 hash implementations can be enabled when CONFIG_CRYPTO_HASH is turned off, causing a link error: crypto/built-in.o: In function `ghash_mod_init': (.init.text+0xd0): undefined reference to `crypto_register_shash' crypto/built-in.o: In function `ghash_mod_exit': (.exit.text+0xb4): undefined reference to `crypto_unregister_shash' crypto/built-in.o: In function `poly1305_mod_init': (.init.text+0xb4): undefined reference to `crypto_register_shash' crypto/built-in.o: In function `poly1305_mod_exit': (.exit.text+0x98): undefined reference to `crypto_unregister_shash' This adds an explicit 'select', like all other hashes have it.
