OpenFlow: Process message types via declarations.
[tcpdump] / print-openflow-1.0.c
1 /*
2 * This module implements decoding of OpenFlow protocol version 1.0 (wire
3 * protocol 0x01). The decoder implements terse (default), detailed (-v) and
4 * full (-vv) output formats and, as much as each format implies, detects and
5 * tries to work around sizing anomalies inside the messages. The decoder marks
6 * up bogus values of selected message fields and decodes partially captured
7 * messages up to the snapshot end. It is based on the specification below:
8 *
9 * [OF10] https://www.opennetworking.org/wp-content/uploads/2013/04/openflow-spec-v1.0.0.pdf
10 *
11 * Most functions in this file take the following arguments:
12 * * cp -- the pointer to the first octet to decode
13 * * len -- the declared length of the structure to decode
14 * The convention is that a printer function returns iff the given structure is
15 * completely within the packet buffer; otherwise it processes the part that is
16 * within the buffer, sooner of later takes the "truncated packet" shortcut via
17 * longjmp() and never returns. With that in mind, the function may return
18 * without printing the structure completely if it is invalid or the ndo_vflag
19 * value is not high enough. This way the calling function can try to decode
20 * the next data item.
21 *
22 * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT
23 * messages is done only when the verbosity level set by command-line argument
24 * is "-vvv" or higher. In that case the verbosity level is temporarily
25 * decremented by 3 during the nested frame decoding. For example, running
26 * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
27 * the nested frames.
28 *
29 * Partial decoding of Big Switch Networks vendor extensions is done after the
30 * oftest (OpenFlow Testing Framework) and Loxigen (library generator) source
31 * code.
