From 0e4053d1522e377d75276c1cafd3b53ac9242bc9 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Mon, 23 Jun 2014 19:41:05 +0300 Subject: [PATCH] crypto: sha512_ssse3 - fix byte count to bit count conversion commit cfe82d4f45c7cc39332a2be7c4c1d3bf279bbd3d upstream. Byte-to-bit-count computation is only partly converted to big-endian and is mixing in CPU-endian values. Problem was noticed by sparce with warning: CHECK arch/x86/crypto/sha512_ssse3_glue.c arch/x86/crypto/sha512_ssse3_glue.c:144:19: warning: restricted __be64 degrades to integer arch/x86/crypto/sha512_ssse3_glue.c:144:17: warning: incorrect type in assignment (different base types) arch/x86/crypto/sha512_ssse3_glue.c:144:17: expected restricted __be64 arch/x86/crypto/sha512_ssse3_glue.c:144:17: got unsigned long long Signed-off-by: Jussi Kivilinna Acked-by: Tim Chen Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman --- arch/x86/crypto/sha512_ssse3_glue.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/crypto/sha512_ssse3_glue.c b/arch/x86/crypto/sha512_ssse3_glue.c index 6cbd8df..9f5e71f 100644 --- a/arch/x86/crypto/sha512_ssse3_glue.c +++ b/arch/x86/crypto/sha512_ssse3_glue.c @@ -141,7 +141,7 @@ static int sha512_ssse3_final(struct shash_desc *desc, u8 *out) /* save number of bits */ bits[1] = cpu_to_be64(sctx->count[0] << 3); - bits[0] = cpu_to_be64(sctx->count[1] << 3) | sctx->count[0] >> 61; + bits[0] = cpu_to_be64(sctx->count[1] << 3 | sctx->count[0] >> 61); /* Pad out to 112 mod 128 and append length */ index = sctx->count[0] & 0x7f; -- 2.7.4
