2012-05-01	l2tp: introduce L2TPv3 IP encapsulation support for IPv6	Chris Elston	1	-0/+17
	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.

2012-05-01	l2tp: netlink api for l2tpv3 ipv6 unmanaged tunnels	Chris Elston	1	-0/+2
	This patch adds support for unmanaged L2TPv3 tunnels over IPv6 using the netlink API. We already support unmanaged L2TPv3 tunnels over IPv4. A patch to iproute2 to make use of this feature will be submitted separately.

2010-04-03	l2tp: Add netlink control API for L2TP	James Chapman	1	-0/+125
	In L2TPv3, we need to create/delete/modify/query L2TP tunnel and session contexts. The number of parameters is significant. So let's use netlink. Userspace uses this API to control L2TP tunnel/session contexts in the kernel. The previous pppol2tp driver was managed using [gs]etsockopt(). This API is retained for backwards compatibility. Unlike L2TPv2 which carries only PPP frames, L2TPv3 can carry raw ethernet frames or other frame types and these do not always have an associated socket family. Therefore, we need a way to use L2TP sessions that doesn't require a socket type for each supported frame type. Hence netlink is used.

2010-04-03	l2tp: Add L2TPv3 IP encapsulation (no UDP) support	James Chapman	1	-0/+38
	This patch adds a new L2TPIP socket family and modifies the core to handle the case where there is no UDP header in the L2TP packet. L2TP/IP uses IP protocol 115. Since L2TP/UDP and L2TP/IP packets differ in layout, the datapath packet handling code needs changes too. Userspace uses an L2TPIP socket instead of a UDP socket when IP encapsulation is required. We can't use raw sockets for this because the semantics of raw sockets don't lend themselves to the socket-per-tunnel model - we need to Signed-off-by: David S. Miller <davem@davemloft.net>
