From 3f602b08dec32c418fc391fc838db357aab84f8a Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Mon, 25 Apr 2011 19:39:24 +0000 Subject: xfrm: Fix replay window size calculation on initialization On replay initialization, we compute the size of the replay buffer to see if the replay window fits into the buffer. This computation lacks a mutliplication by 8 because we need the size in bit, not in byte. So we might return an error even though the replay window would fit into the buffer. This patch fixes this issue. Signed-off-by: Steffen Klassert Acked-by: Herbert Xu Signed-off-by: David S.
