| * This module implements decoding of OpenFlow protocol version 1.0 (wire |
| * protocol 0x01). The decoder implements terse (default), detailed (-v) and |
| * full (-vv) output formats and, as much as each format implies, detects and |
| * tries to work around sizing anomalies inside the messages. The decoder marks |
| * up bogus values of selected message fields and decodes partially captured |
| * messages up to the snapshot end. It is based on the specification below: |
| * |
| * [OF10] http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf |
| * |
| * Most functions in this file take 3 arguments into account: |
| * * cp -- the pointer to the first octet to decode |
| * * len -- the length of the current structure as declared on the wire |
| * * ep -- the pointer to the end of the captured frame |
| * They return either the pointer to the next not-yet-decoded part of the frame |
| * or the value of ep, which means the current frame processing is over as it |
| * has been fully decoded or is invalid or truncated. This way it is possible |
| * to chain and nest such functions uniformly to decode an OF1.0 message, which |
| * consists of several layers of nested structures. |
| * |
| * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT |
| * messages is done only when the verbosity level set by command-line argument |
| * is "-vvv" or higher. In that case the verbosity level is temporarily |
| * decremented by 3 during the nested frame decoding. For example, running |
| * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of |
| * the nested frames. |
| * |
| * Partial decoding of Big Switch Networks vendor extensions is done after the |
| * oftest (OpenFlow Testing Framework) and Loxigen (library generator) source |
| * code. |
