TLV

TLV is the representative of type-length-value.

It might be found in a binary file format or a network protocol.

Brief

One TLV Object:

 1 Byte   2 Bytes  $Length Bytes
+-------+---------+-------------+
| Type  | Length  |    Value    |
+-------+---------+-------------+

Serial TLV Objects:

 1 Byte   2 Bytes  $Length Bytes 1 Byte   2 Bytes  $Length Bytes
+-------+---------+-------------+-------+---------+-------------+
| Type  | Length  |    Value    | Type  | Length  |    Value    | ...
+-------+---------+-------------+-------+---------+-------------+

Embedded TLV Objects:

 1 Byte   2 Bytes          $Length Bytes
                   1 Byte   2 Bytes  $Length Bytes
+-------+---------+-------+---------+-------------+
| Type  | Length  | Type  | Length  |    Value    |
+-------+---------+-------+---------+-------------+

Wireshark Plugin

• Put wssdl and tlv.lua to ~/.config/wireshark/plugins
• The UDP port 8327 will be decoded as tlv protocol.

Changes

• Set TLV length to 2 bytes.
• Added additional test.
