IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly deploy IPv6 unicast service to IPv4 sites to which it provides customer premise equipment. Like 6to4, it utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 prefix of its own in place of the fixed 6to4 prefix. With this option enabled, the SIT driver offers 6rd functionality by providing additional ioctl API to configure the IPv6 Prefix for in stead of static 2002::/16 for 6to4. Original patch was done by Alexandre Cassen <acassen@freebox.fr> based on old Internet-Draft. Signed-off-by: NYOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: NDavid S.

We currently dirty a cache line to update tunnel device stats (tx_packets/tx_bytes). We better use the txq->tx_bytes/tx_packets counters that already are present in cpu cache, in the cache line shared with txq->_xmit_lock This patch extends IPTUNNEL_XMIT() macro to use txq pointer provided by the caller. Also &tunnel->dev->stats can be replaced by &dev->stats Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When requesting all prl entries (kprl.addr == INADDR_ANY) and there are more prl entries than there is space passed from userspace, the existing code would always copy cmax+1 entries, which is more than can be handled.

This reverts commit 64506929. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by: NSascha Hlusiak <contact@saschahlusiak.de> Acked-by: NFred L. Templin <Fred.L.Templin@boeing.com> Signed-off-by: NDavid S.

It seems recursion field from "struct ip_tunnel" is not anymore needed. recursion prevention is done at the upper level (in dev_queue_xmit()), since we use HARD_TX_LOCK protection for tunnels. This avoids a cache line ping pong on "struct ip_tunnel" : This structure should be now mostly read on xmit and receive paths.

if tunnel parameters have frag_off set to IP_DF, pmtudisc on the ipv4 link will be performed by deriving the mtu from the ipv4 link and setting the DF-Flag of the encapsulating IPv4 Header. If fragmentation is needed on the way, the IPv4 pmtu gets adjusted, the ipv6 package will be resent eventually, using the new and lower mtu and everyone is happy. If the frag_off parameter is unset, the mtu for the tunnel will be derived from the tunnel device or the ipv6 pmtu, which might be higher than the ipv4 pmtu. In that case we must allow the fragmentation of the IPv4 packet because the IPv6 mtu wouldn't 'learn' from the adjusted IPv4 pmtu, resulting in frequent icmp_frag_needed and package loss on the IPv6 layer. This patch allows fragmentation when tunnel was created with parameter nopmtudisc, like in ipip/gre tunnels. Signed-off-by: NSascha Hlusiak <contact@saschahlusiak.de> Signed-off-by: NDavid S.

dev_net_set() should be the very first thing after alloc_netdev(). "ndo_" changes turned simple assignment (which is OK to do before netns assignment) into quite non-trivial operation (which is not OK, init_net was used).
