/*
|
|
|
|
* 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:

|
|
* Most functions in this file take the following arguments:
|
2015-07-06 02:16:08 +00:00
|
|
|
* * cp -- the pointer to the first octet to decode
|
2023-05-10 15:02:34 +00:00
|
|
|
* * len -- the declared length of the structure to decode
|
|
|
|
* The convention is that a printer function returns iff the given structure is
|
|
|
|
* completely within the packet buffer; otherwise it processes the part that is
|
|
|
|
* within the buffer, sooner of later takes the "truncated packet" shortcut via
|
|
|
|
* longjmp() and never returns. With that in mind, the function may return
|
|
|
|
* without printing the structure completely if it is invalid or the ndo_vflag
|
|
|
|
* value is not high enough. This way the calling function can try to decode
|
|
|
|
* the next data item.

|
|
|
* 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.
