From 4b90a603a1b21d63cf743cc833680cb195a729f6 Mon Sep 17 00:00:00 2001 From: Nick Bowler Date: Thu, 10 Nov 2011 09:01:27 +0000 Subject: [PATCH] ah: Don't return NET_XMIT_DROP on input. When the ahash driver returns -EBUSY, AH4/6 input functions return NET_XMIT_DROP, presumably copied from the output code path. But returning transmit codes on input doesn't make a lot of sense. Since NET_XMIT_DROP is a positive int, this gets interpreted as the next header type (i.e., success). As that can only end badly, remove the check. Signed-off-by: Nick Bowler Signed-off-by: David S.
