From e74c04fc9fb2600470fe79a69d3ec6b0db95faec Mon Sep 17 00:00:00 2001 From: Jakub Grajciar Date: Mon, 4 Jan 2021 11:28:33 +0100 Subject: libmemif: refactor examples - icmp_responder: responds to ICMPv4 and ARP requests - loopback: connects two interfaces and sends a verification packet from master memif to slave memif where it is looped back - loopback (reverse path): reverses direction of packet in loopback application (slave memif to master memif) Type: refactor Signed-off-by: Jakub Grajciar Change-Id: Ie90aaa3367269408efb6c5d538ad5aa827432238 Signed-off-by: Dave Wallace --- extras/libmemif/examples/common/icmp_proto.h | 48 ++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 extras/libmemif/examples/common/icmp_proto.h (limited to 'extras/libmemif/examples/common/icmp_proto.h') diff --git a/extras/libmemif/examples/common/icmp_proto.h b/extras/libmemif/examples/common/icmp_proto.h new file mode 100644 index 00000000000..e346a3b13f7 --- /dev/null +++ b/extras/libmemif/examples/common/icmp_proto.h @@ -0,0 +1,48 @@ +/* + *------------------------------------------------------------------ + * Copyright (c) 2017 Cisco and/or its affiliates. + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at: + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + *------------------------------------------------------------------ + */ + +#ifndef _ICMP_PROTO_H_ +#define _ICMP_PROTO_H_ + +typedef enum +{ + ICMPR_FLOW_MODE_ETH = 0, + ICMPR_FLOW_MODE_IP, +} icmpr_flow_mode_t; + +int resolve_packet (void *in_pck, ssize_t in_size, void *out_pck, + uint32_t *out_size, uint8_t ip_addr[4], + uint8_t hw_addr[6]); + +/* resolve packet in place */ +int resolve_packet_zero_copy (void *pck, uint32_t *size, uint8_t ip_addr[4], + uint8_t hw_addr[6]); + +/* resolve packet in place and add eth encap */ +int resolve_packet_zero_copy_add_encap (void **pck, uint32_t *size, + uint8_t ip_addr[4]); + +int generate_packet (void *pck, uint32_t *size, uint8_t saddr[4], + uint8_t daddr[4], uint8_t hw_daddr[6], uint32_t seq); + +int generate_packet2 (void *pck, uint32_t *size, uint8_t saddr[4], + uint8_t daddr[4], uint8_t hw_daddr[6], uint32_t seq, + icmpr_flow_mode_t); + +int print_packet (void *pck); + +#endif /* _ICMP_PROTO_H_ */ -- cgit 1.2.3-korg
