  • a43a9ef6a   vxlan: do not receive IPv4 packets on IPv6 socket ... Browse Code »

    By default (subject to the sysctl settings), IPv6 sockets listen also for
    IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in
    packets received through an IPv6 socket.

    In addition, it's currently not possible to have both IPv4 and IPv6 vxlan
    tunnel on the same port (unless bindv6only sysctl is enabled), as it's not
    possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's
    no way to specify both IPv4 and IPv6 remote/group IP addresses.

    Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not
    done globally in udp_tunnel, as l2tp and tipc seems to work okay when
    receiving IPv4 packets on IPv6 socket and people may rely on this behavior.
    The other tunnels (geneve and fou) do not support IPv6.

  • d998f8efa   udp: Do not require sock in udp_tunnel_xmit_skb ... Browse Code »

    The UDP tunnel transmit functions udp_tunnel_xmit_skb and
    udp_tunnel6_xmit_skb include a socket argument. The socket being
    passed to the functions (from VXLAN) is a UDP created for receive
    side. The only thing that the socket is used for in the transmit
    functions is to get the setting for checksum (enabled or zero).
    This patch removes the argument and and adds a nocheck argument
    for checksum setting. This eliminates the unnecessary dependency
    on a UDP socket for UDP tunnel transmit.

  • cfdf1e1ba   udptunnel: Add SKB_GSO_UDP_TUNNEL during gro_complete. ... Browse Code »

    When doing GRO processing for UDP tunnels, we never add
    SKB_GSO_UDP_TUNNEL to gso_type - only the type of the inner protocol
    is added (such as SKB_GSO_TCPV4). The result is that if the packet is
    later resegmented we will do GSO but not treat it as a tunnel. This
    results in UDP fragmentation of the outer header instead of (i.e.) TCP
    segmentation of the inner header as was originally on the wire.

  • 6a93cc905   udp-tunnel: Add a few more UDP tunnel APIs ... Browse Code »

    Added a few more UDP tunnel APIs that can be shared by UDP based
    tunnel protocol implementation. The main ones are highlighted below.

    setup_udp_tunnel_sock() configures UDP listener socket for
    receiving UDP encapsulated packets.

    udp_tunnel_xmit_skb() and upd_tunnel6_xmit_skb() transmit skb
    using UDP encapsulation.

    udp_tunnel_sock_release() closes the UDP tunnel listener socket.
