2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion1-1/+1
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-02-06vlib: epoll on worker threadsDamjan Marion1-0/+1
This patch teaches worer threads to sleep and to be waken up by kernel if there is activity on file desctiptors assigned to that thread. It also adds counters to epoll file descriptors and new debug cli 'show unix file'. Change-Id: Iaf67869f4aa88ff5b0a08982e1c08474013107c4 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-12-15Fix icmp/udp/tcp punt/drop pathsVijayabhaskar Katamreddy1-3/+7
Send packets to ip4/6_punt/drop nodes instead of error-drop/punt nodes dbarach: clean up an annoying checkstyle issue: indent 2.2.10 (OpenSUSE version) and indent 2.2.11 (Ubuntu / CentOS versions) had an artistic disagreement about ip_frag.c.

2017-12-08punt: fix tracing for partially traced chainsKlement Sekera1-4/+5
This fixes a crash if the first buffer in buffer chain is not traced, but some other buffer (mid-chain) is. Change-Id: I2c9f529ae0bc3263d20981e0cb83ce24ed292bd8 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2017-09-20tcp: add option to punt trafficPierre Pfister1-24/+42
Until now, if the stack didn't find a connection for a packet, it sent back a reset. With the punt option enabled, packets are now enqueued to error-punt where they can be handed off to the host os.

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>
