From 9ffea4cb2306945b5df5f28bb8686333fe666bf1 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 20 Nov 2014 17:05:53 -0800 Subject: crypto: prefix module autoloading with "crypto-" commit 5d26a105b5a73e5635eae0629b42fa0a90e07b7b upstream. This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook Signed-off-by: Herbert Xu [bwh: Backported to 3.2: - Adjust filenames - Drop changes to algorithms and drivers we don't have - Add aliases to generic C implementations that didn't need them before] Signed-off-by: Ben Hutchings --- crypto/api.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'crypto/api.c') diff --git a/crypto/api.c b/crypto/api.c index cea3cf6..ac80794 100644 --- a/crypto/api.c +++ b/crypto/api.c @@ -222,11 +222,11 @@ struct crypto_alg *crypto_larval_lookup(const char *name, u32 type, u32 mask) alg = crypto_alg_lookup(name, type, mask); if (!alg) { - request_module("%s", name); + request_module("crypto-%s", name); if (!((type ^ CRYPTO_ALG_NEED_FALLBACK) & mask & CRYPTO_ALG_NEED_FALLBACK)) - request_module("%s-all", name); + request_module("crypto-%s-all", name); alg = crypto_alg_lookup(name, type, mask); } -- cgit v1.1
