    Fix clang build warning:

    ./include/uapi/linux/gtp.h:1:9: warning: '_UAPI_LINUX_GTP_H_' is
    used as a header guard here, followed by #define of a different
    macro [-Wheader-guard]

    fix by defining _UAPI_LINUX_GTP_H_ and not _UAPI_LINUX_GTP_H__

  • 459aa660e   gtp: add initial driver for datapath of GPRS Tunneling Protocol (GTP-U) ... Browse Code »

    This is an initial implementation of a netdev driver for GTP datapath
    (GTP-U) v0 and v1, according to the GSM TS 09.60 and 3GPP TS 29.060
    standards. This tunneling protocol is used to prevent subscribers from
    accessing mobile carrier core network infrastructure.

    This implementation requires a GGSN userspace daemon that implements the
    signaling protocol (GTP-C), such as OpenGGSN [1]. This userspace daemon
    updates the PDP context database that represents active subscriber
    sessions through a genetlink interface.

    For more context on this tunneling protocol, you can check the slides
    that were presented during the NetDev 1.1 [2].

    Only IPv4 is supported at this time.
