Subject: Unaligned kernel access in crypto/sha1.c
Date: Thu, 16 Sep 2004 16:16:38 -0700 [thread overview]
Message-ID: <20040916231638.GA32514@lucon.org> (raw)
I got
Sep 16 15:45:32 gnu-2 kernel: kernel unaligned access to
0xa0000002001c008e, ip=0xa0000001002135e0
Sep 16 15:45:37 gnu-2 kernel: kernel unaligned access to
0xa0000002002d005e, ip=0xa0000001002135e0

Sep 16 15:45:37 gnu-2 kernel: kernel unaligned access to
0xa0000002002d008e, ip=0xa0000001002135e0
on ia64 from sha1_transform in crypto/sha1.c:
/* Hash a single 512-bit block. This is the core of the algorithm. */
static void sha1_transform(u32 *state, const u8 *in)
{
u32 a, b, c, d, e;
u32 block32[16];
/* convert/copy data to workspace */
for (a = 0; a < sizeof(block32)/sizeof(u32); a++)
block32[a] = be32_to_cpu (((const u32 *)in)[a]);
^^^^^^^^^^^^^^^^
This may not be aligned for u32 on ia64.
