inet: Call skb_orphan before tproxy activates

2009-08-16T21:18:17Z

[ Upstream commit 71f9dacd2e4d233029e9e956ca3f79531f411827 ] As transparent proxying looks up the socket early and assigns it to the skb for later processing, we must drop any existing socket ownership prior to that in order to distinguish between the case where tproxy is active and where it is not.

ipv6: Plug sk_buff leak in ipv6_rcv (net/ipv6/ip6_input.c)

2009-03-27T07:17:45Z

Commit 778d80be52699596bf70e0eb0761cf5e1e46088d (ipv6: Add disable_ipv6 sysctl to disable IPv6 operaion on specific interface) seems to have introduced a leak of sk_buff's for ipv6 traffic, at least in some configurations where idev is NULL, or when ipv6 is disabled via sysctl. The problem is that if the first condition of the if-statement returns non-NULL, it returns an skb with only one reference, and when the other conditions apply, execution jumps to the "out" label, which does not call kfree_skb for it. To plug this leak, change to use the "drop" label instead. (this relies on it being ok to call kfree_skb on NULL) This also allows us to avoid calling rcu_read_unlock here, and removes the only user of the "out" label.

IPv6: Fix multicast routing bugs.

2009-01-28T06:39:59Z

This patch addresses the IPv6 multicast routing issues described below. It was tested with XORP 1.4/1.5 as the IPv6 PIM-SM routing daemon against FreeBSD peers. net/ipv6/ip6_input.c: - Don't try to forward link-local multicast packets. - Don't reset skb2->dev before calling ip6_mr_input() so packets can be identified as coming from the PIM register vif properly. net/ipv6/ip6mr.c: - Fix incoming PIM register messages processing: * The IPv6 pseudo-header should be included when checksumming PIM messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1). * Packets decapsulated from PIM register messages should have skb->protocol ETH_P_IPV6. - Enable/disable IPv6 multicast forwarding on the corresponding interface when a routing daemon adds/removes a multicast virtual interface. - Remove incorrect skb_pull() to fix userspace signaling. - Enable/disable global IPv6 multicast forwarding when an IPv6 multicast routing socket is opened/closed. net/ipv6/route.c: - Don't use strict routing logic for packets decapsulated from PIM register messages (similar to disabling rp_filter for the IPv4 case).
