* XFRM,IPv6: initialize ip6_dst_blackhole_ops.kmem_cachepArnaud Ebalard2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ip6_dst_blackhole_ops.kmem_cachep is not expected to be NULL (i.e. to be initialized) when dst_alloc() is called from ip6_dst_blackhole().

* ipsec: Use the correct ip_local_out functionHerbert Xu2008-05-20
| | | | | | | | | | | | | | | | | | | Because the IPsec output function xfrm_output_resume does its own dst_output call it should always call __ip_local_output instead of ip_local_output as the latter may invoke dst_output directly. Otherwise the return values from nf_hook and dst_output may clash as they both use the value 1 but for different purposes. When that clash occurs this can cause a packet to be used after it has been freed which usually leads to a crash. Because the offending value is only returned from dst_output with qdiscs such as HTB, this bug is normally not visible. Thanks to Marco Berizzi for his perseverance in tracking this down.

* [NETNS][IPV6] rt6_stats - make the stats per network namespaceBenjamin Thery2008-03-04
| | | | | | | | | | The rt6_stats is now per namespace with this patch. It is allocated when a network namespace is created and freed when the network namespace exits and references are relative to the network namespace.

* [NETNS][IPV6] rt6_stats - dynamically allocate the routes statisticsDaniel Lezcano2008-03-04
| | | | | | | | | | This patch allocates the rt6_stats struct dynamically when the fib6 is initialized. That provides the ability to create several instances of this structure for the network namespaces.
