2012-05-01l2tp: let iproute2 create L2TPv3 IP tunnels using IPv6James Chapman1-22/+50
The netlink API lets users create unmanaged L2TPv3 tunnels using iproute2. Until now, a request to create an unmanaged L2TPv3 IP encapsulation tunnel over IPv6 would be rejected with EPROTONOSUPPORT. Now that l2tp_ip6 implements sockets for L2TP IP encapsulation over IPv6, we can add support for that tunnel type. Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S.

2012-05-01l2tp: introduce L2TPv3 IP encapsulation support for IPv6Chris Elston3-0/+812
L2TPv3 defines an IP encapsulation packet format where data is carried directly over IP (no UDP). The kernel already has support for L2TP IP encapsulation over IPv4 (l2tp_ip). This patch introduces support for L2TP IP encapsulation over IPv6. The implementation is derived from ipv6/raw and ipv4/l2tp_ip.

The reset logic after a Rx FIFO overrun will clear the programmed multicast addresses. This patch fixes the issue by reprogramming the registers after the reset.

TCP coalesce can check if skb to be merged has its skb->head mapped to a page fragment, instead of a kmalloc() area. We had to disable coalescing in this case, for performance reasons. We 'upgrade' skb->head as a fragment in itself. This reduces number of cache misses when user makes its copies, since a less sk_buff are fetched. This makes receive and ofo queues shorter and thus reduce cache line misses in TCP stack.

2012-05-01tg3: provide frags as skb headEric Dumazet2-10/+66
This patch converts tg3 driver, one of our reference drivers, to use new build_skb() api in frag mode. Instead of using kmalloc() to allocate the memory block that will be used by build_skb() as skb->head, we use a page fragment. This is a followup of patch "net: allow skb->head to be a page fragment" This allows GRO, TCP coalescing, and splice() to be more efficient.

2012-05-01net: allow skb->head to be a page fragmentEric Dumazet5-12/+25
skb->head is currently allocated from kmalloc(). This is convenient but has the drawback the data cannot be converted to a page fragment if needed. We have three spots were it hurts : 1) GRO aggregation When a linear skb must be appended to another skb, GRO uses the frag_list fallback, very inefficient since we keep all struct sk_buff around. So drivers enabling GRO but delivering linear skbs to network stack aren't enabling full GRO power. 2) splice(socket -> pipe). We must copy the linear part to a page fragment. This kind of defeats splice() purpose (zero copy claim) 3) TCP coalescing. Recently introduced, this permits to group several contiguous segments into a single skb. This shortens queue lengths and save kernel memory, and greatly reduce probabilities of TCP collapses. This coalescing doesnt work on linear skbs (or we would need to copy data, this would be too slow) Given all these issues, the following patch introduces the possibility of having skb->head be a fragment in itself. We use a new skb flag, skb->head_frag to carry this information. build_skb() is changed to accept a frag_size argument. Drivers willing to provide a page fragment instead of kmalloc() data will set a non zero value, set to the fragment size. Then, on situations we need to convert the skb head to a frag in itself, we can check if skb->head_frag is set and avoid the copies or various fallbacks we have. This means drivers currently using frags could be updated to avoid the current skb->head allocation and reduce their memory footprint (aka skb truesize). (thats 512 or 1024 bytes saved per skb). This also makes bpf/netfilter faster since the 'first frag' will be part of skb linear part, no need to copy data.
