The purpose of this macro was to enable the file-by-file switch to NDO,
after which only tcpdump.c had a use of it and the definitions guarded
by it. Update tcpdump.c not to require them any more and dismiss the
unused definitions.
The new function goes into print-openflow.c as vendor name decoding is
the same in all versions of OpenFlow (although in 1.0 it is "vendor"
and in subsequent versions it is "experimenter"). The mapping is from:
https://rs.opennetworking.org/wiki/display/PUBLIC/ONF+Registry
For each decoder that has more than one instance of truncation signaling
and prints the same string in each instance make sure that the string is
declared as "static const char tstr[]" right after the initial includes
block. Where necessary, replace fputs(s, stdout) with equivalent
printf("%s", s).
Don't assume we have <stdint.h>. Instead, use the AC_TYPE_ macros to
ensure we have the C99 intN_t and uintN_t types; we already include
<inttypes.h> in tcpdump-stdinc.h iff we have it.
Get rid of the structure declarations in openflow-1.0.h, as they have
zero-length arrays (not supported by all the compilers people might be
using) and as
1) they're only used in sizeof()
and
2) after each one there's an assertion to check that sizeof()
returns a specific numerical value
so, instead, just #define various _LEN items to those numerical values
and use them.
Add an openflow.h header with a #define for the length of the basic
header, and move the declaration of of10_header_body_print() there.
The new file openflow-1.0.h is a verbatim copy of the file openflow.h
from the openflow-1.0.0.tar.gz distribution. The new file
print-openflow-1.0.c contains a set of functions for OpenFlow 1.0 (wire
protocol 0x01) decoding. Of these functions only
of10_header_body_print() is exported and used by the minimal OpenFlow
decoder.
It is intended that future (1.1, 1.2, 1.3.0) OpenFlow version decoders
are implemented the same way (in modules of their own), since different
versions of OpenFlow specification reuse the same symbols for different
numeric values. This way, print-openflow-1.1.c would include
openflow-1.1.h and so on.
The new test case "of10_p3295-vv" was produced using a Pica8 P-3295
switch and Trema controller running a purpose-built sample application.
This change registers OpenFlow TCP port number and adds processing of
respective packets with openflow_print(), a new function that
understands the minimal OpenFlow header format and can iterate over
messages within a snapshot that starts with the header.
