l2tp: introduce L2TPv3 IP encapsulation support for IPv6 2012-05-01T13:30:55+00:00 Chris Elston celston@katalix.com 2012-04-29T21:48:54+00:00 a32e0eec7042b21ccb52896cf715e3e2641fed93 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 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.
