Dissector for HSR and PRP-1
Here is a patch that adds a dissector for HSR and for PRP-1. Both protocols are defined in IEC62439 Part 3. (High-availability Seamless Redundancy / Parallel Redundancy Protocol)
The existing PRP dissector has been refactored to support both the old PRP (now called PRP-0) and the new PRP-1.
There are three distinct dissectors:
- HSR (ethertype 892F)
- HSR/PRP supervision (ethertype 88FB)
- PRP-0 and PRP-1 (trailer dissector; disabled by default)
From me :
* Fix Clang Warning
* Add modification for CMakeLists.txt

keys to have _uint in their names, to match the routines that handle
dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

Add support for dissecting TDLS (IEEE 802.11z) frames.
These are mostly used as Action frames that are encapsulated in Data frames (to go through any AP).

draft-ietf-isis-ext-eth specifies an extension to current Ethernet Frame
specifications for hardware and frame format to support payloads greater than
1500 Bytes for Type interpretation and Length interpretation frames.
The extension introduced by draft-ietf-isis-ext-eth is currently used by Cisco
Systems' IS-IS routing protocol implementation when running IS-IS over Ethernet
links with large MTU.

This is necessary in case a subdissector had changed it but was unable to
restore it (due to the exception).
Remove check_col().

From me: A few minor changes:
- col-clear() not req'd;
- Use 'gint32 length' rather than 'guint8 length';
- Use ENC_NA instead of FALSE/TRUE in two cases;
- Move global tdmoe_handle to be local to proto_reg_handoff...

This is a patch for a new dissector that decodes Nokia Siemens Networks'

This contains the source for dissecting TTEthernet packets (including Protocol Control Frames) conforming to our TTEthernet specification as dissector for Wireshark.

Check whether the length field in an 802.3 header doesn't go past the
(presumed) end of the payload.

This is a dissector for the Parallel Redundancy Protocol (PRP) defined in chapter
6 of the IEC 62439.
PRP uses two independent networks in parallel and allows redundancy without
switchovers.
The protocol is sending Mac multicast messages with Ethertype 0x88fb. In
addition to that it adds to every Ethernet frame a 4 byte trailer before
the FCS. The trailer is detected by checking a size field and an identifier
which are part of the trailer. Therefore, if the last 4 bytes of a frame
match a correct trailer they get interpreted as a trailer, although it was
probably not a real one.
Note:
This is a post-dissector which means it gets called for every frame. So as
to not cause a performance hit for every Wireshark user (who may not even be
looking at Ethernet frames) it currently disables itself every time Wireshark
starts up. (There should be a better way to do this--maybe different Profiles
(as discussed on -dev recently) is the way to go.)
From me:
Put ETHERTYPE_PRP (not IANA registered) in etypes.h and packet-ethertype.c

This patch adds a heuristic dissector to the ethernet trailer under the
keystring "eth.trailer". This allows for other protocol plugins which coopt
the ethernet trailer for their own devices to register for trailer traffic
without requiring any further changes to the executable.

- if offset is 0, tvb_length is the same as tvb_length_remaining, just faster.
Replace
- col_append_fstr() with faster col_append_str()
- col_add_str() with col_set_str()
when it's safe
