Description J.H.M. Dassen (Ray) 2008-05-06 23:25:13 UTC
Problem Description:

RFC 1122 does not have a section 3.1.2.2. The requirement to silently
discard packets with a bad checksum is in section 3.2.1.2 instead.

Proposed patch:

diff --git a/net/ipv4/ip_input.c b/net/ipv4/ip_input.c
index 212734c..5bdb8f4 100644
--- a/net/ipv4/ip_input.c
+++ b/net/ipv4/ip_input.c
@@ -394,7 +394,7 @@ int ip_rcv(struct sk_buff *skb, struct net_device *dev, struct packet_type *pt,
 	iph = skb->nh.iph;
 
 	/*
-	 *	RFC1122: 3.1.2.2 MUST silently discard any IP frame that fails the checksum.
+	 *	RFC1122: 3.2.1.2 MUST silently discard any IP frame that fails the checksum.
 	 *
 	 *	Is the datagram acceptable?
