ipv6: Copy cork options in ip6_append_data

2009-02-17T17:46:21Z

[ Upstream commit 0178b695fd6b40a62a215cbeb03dd51ada3bb5e0 ] As the options passed to ip6_append_data may be ephemeral, we need to duplicate it for corking. This patch applies the simplest fix which is to memdup all the relevant bits. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

ipv6: Fix OOPS in ip6_dst_lookup_tail().

2008-09-09T20:51:35Z

This fixes kernel bugzilla 11469: "TUN with 1024 neighbours: ip6_dst_lookup_tail NULL crash" dst->neighbour is not necessarily hooked up at this point in the processing path, so blindly dereferencing it is the wrong thing to do. This NULL check exists in other similar paths and this case was just an oversight. Also fix the completely wrong and confusing indentation here while we're at it. Based upon a patch by Evgeniy Polyakov. Signed-off-by: Neil Horman Signed-off-by: David S. Miller

netns: Add network namespace argument to rt6_fill_node() and ipv6_dev_get_saddr()

2008-08-14T22:33:21Z

ipv6_dev_get_saddr() blindly de-references dst_dev to get the network namespace, but some callers might pass NULL. Change callers to pass a namespace pointer instead. Signed-off-by: Brian Haley Signed-off-by: David S. Miller

ipv6: Do not drop packet if skb->local_df is set to true

2008-08-04T04:15:59Z

The old code will drop IPv6 packet if ipfragok is not set, since ipfragok is obsoleted, will be instead by used skb->local_df, so this check must be changed to skb->local_df. This patch fix this problem and not drop packet if skb->local_df is set to true. Signed-off-by: Wei Yongjun Acked-by: Herbert Xu Signed-off-by: David S. Miller

ipv6: Fix ip6_xmit to send fragments if ipfragok is true

2008-08-01T03:46:47Z

SCTP used ip6_xmit() to send fragments after received ICMP packet too big message. But while send packet used ip6_xmit, the skb->local_df is not initialized. So when skb if enter ip6_fragment(), the following code will discard the skb. ip6_fragment(...) { if (!skb->local_df) { ... return -EMSGSIZE; } ... } SCTP do the following step: 1. send packet ip6_xmit(skb, ipfragok=0) 2. received ICMP packet too big message 3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1) This patch fixed the problem by set local_df if ipfragok is true.

net: convert BUG_TRAP to generic WARN_ON

2008-07-26T04:43:18Z

Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future. I could make at least one BUILD_BUG_ON conversion. Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller

net: Discard and warn about LRO'd skbs received for forwarding

2008-06-19T23:22:28Z

Add skb_warn_if_lro() to test whether an skb was received with LRO and warn if so. Change br_forward(), ip_forward() and ip6_forward() to call it) and discard the skb if it returns true. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
