[netsniff-ng] [PATCH v2 10/16] trafgen: l2: Add ARP header generation logic

Add ARP proto header fields generation via src mac, src ip, dst mac, dst ip & operaion. By default Ethernet proto will be initialized, and ARP Announcement request is filled. Signed-off-by: Vadim Kochan --- trafgen_l2.c | 52

[netsniff-ng] [PATCH v2 16/16] trafgen: man: Add help for Ethernet, ARP, IPv4, UDP headers

Add description (basic syntax, proto header fields) for newer added proto headers: Ethernet, ARP, IPv4, UDP. Signed-off-by: Vadim Kochan --- trafgen.8 | 174 ++ 1 file changed, 174 insertions(+) diff --git

[netsniff-ng] [PATCH v2 08/16] trafgen: parser: Add syntax to generate Ethernet header

Add syntax for generating Ethernet header fields like: { eth(prot=0x0800, da=11:22:33:44:55:66), fill(0xff, 60) } { eth(prot=0x0800) } { eth() } It is important that proto_init is called before fields will be filled to initialize the specified proto with header fields.

[netsniff-ng] [PATCH v2 09/16] trafgen: proto: Add func to fill field with device ipv4 addr

Add helper which fill device's ipv4 addr to the specified proto field. It will be used by such protos like ARP, IPv4, etc. Signed-off-by: Vadim Kochan --- trafgen_proto.c | 32 trafgen_proto.h | 3 +++ 2 files changed, 35 insertions(+) diff

[netsniff-ng] [PATCH v2 14/16] trafgen: l4: Add UDP header generation logic

Add trafgen_l4.c module with implementation of UDP header fields gneration. UDP proto generation logic automaticaly sets by default IPPROTO_UDP to the lower proto if it is IPv4, also cscum is calculated if it is not set by user. Signed-off-by: Vadim Kochan ---

[netsniff-ng] [PATCH v2 02/16] trafgen: Add helper to get current packet

Add current_packet() helper for getting current used packet and make it public to other modules. It will be used by proto generation logic. Signed-off-by: Vadim Kochan --- trafgen_conf.h | 2 ++ trafgen_parser.y | 5 + 2 files changed, 7 insertions(+) diff --git

[netsniff-ng] [PATCH v2 03/16] trafgen: Add basic proto generation logic

Add new trafgen_proto.c module with basic proto header fields generation logic. Each proto must implement proto_hdr struct and register it to the global proto list. Proto header consist from set of fields, and each field must be described via proto_field struct by specifying unique id, len,

[netsniff-ng] [PATCH v2 01/16] trafgen: Export set_fill func

[netsniff-ng] [PATCH v2 12/16] trafgen: l3: Add IPv4 header generation backend

Add L3 module for implement L3 layer protos generation. Implemented generating of IPv4 header with all fields except options. By default IPv4 address of output device is used as src ip address. On finish (after packet is specified) - total len & checksum is calculated. Meanwhile Ethernet proto

[netsniff-ng] [PATCH v2 06/16] trafgen: l2: Add Ethernet proto header generation
