2022-09-05ip: fix punt socket overflowBenoît Ganne1-3/+6
client_pathname is usually smaller than pc->caddr.sun_path. snprint() ensures we stop at the NULL character or sizeof(sun_path) whichever comes 1st. It also guarantees NULL character termination.

2017-09-05PUNT socket: External control plane processes connected via UNIX domain sockets.Ole Troan1-9/+497
An external (to VPP) process can register (over the VPP binary API) to receive control plane packets over a UNIX domain socket. The packets are prepended with a packet descriptor containing meta-data (if_index of interface, etc). Currently only UDP is supported. The socket supports sending of packets/frames as well. The sent packet is prepended with a descriptor, telling VPP to route the packet (via ip4-lookup, ip6-lookup) or as an pre-formed Ethernet frame that is sent directly to interface-output. The intended use case for this is for an external DHCP client or a RIP implementation. New configuration option: punt { socket <socket path> } To register use the punt_socket API message. TODO: - Add support for pre-routing. I.e send L3 packet to given TX interface, but do ARP/ND (ip[46]-rewrite) - Add test scripts - Support for abstract names (starting with \0) - Add rate limiting (COP) - Support for other protocols, e.g. IPv6 ND Change-Id: I4a0afc8020deebb3d9d74686dde694ee5bcb8d0f Signed-off-by: Ole Troan <ot@cisco.com>
