For the conversion of a 16-bit short address in 6lowpan to an IID, there
are several RFCs that produce different results. RFC 4944 section 6
specifies that the conversion uses the given PAN ID and the 16-bit short
address. RFC 6282, on the other hand, specifies thta the conversion only
uses the 16-bit short address and no longer uses the PAN ID.
The current version of the 6lowpan dissector supports only the newer RFC
6282, but there are protocols out there that assume that the address
conversion still abides to RFC 4944.
In order to support these protocols and following the discussion from
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8970
this patch introduces a boolean preference in the 6lowpan dissector that
indicates whether or not the older RFC 4944 should be used for address
conversion. By default, it is set to FALSE, thus leaving the behavior of
the dissector unchanged.
Besides the boolean preference, another helper function
lowpan_addr16_with_panid_to_ifcid has been written that implements the
expected behavior from RFC 4944 using the same hint mechanism already in
place in the dissector for the support of RFC 6282.

The 6lowpan standard specifies a reserved octet in the extended header
of an IP_PROTO_FRAGMENT packet in the same place used for the header
length for other extension headers.
The current version of the 6lowpan dissector displays the reserved octet
and the rest of the header (6 more bytes) together as data, as opposed to
displaying the reserved octet by itself and then the data (using the
data dissector).
This patch does not change the functionality of the dissector in any
way, only how the 7 bytes are displayed. Instead of displaying the
header information and then 7 bytes of data, it displays the reserved
octet and then the data. This is also consistent with the way the ipv6
dissector displays it (showing the reserved octet and its value).
For this purpose, there is a new hf (hf_6lowpan_nhc_ext_reserved) and
the corresponding proto_tree calls. Also, depending on the type of
extension header, the octets sent to the general data dissector are
shifted by one.

IPv6 Extension Headers compressed using IPHC should have a single Pad1

This guarantees correctly-compressed packets are accurately
decompressed, including the specific option padding pattern. (The type of
padding could matter, eg for IPSec authentication - padding options are
authenticated.)
Print a warning note if a non-option header needs padding - this is

I'm not sold on the name or module the proto_data functions live in, but I believe the function arguments are solid and gives us the most flexibility for the future. And search/replace of a function name is easy enough to do.
The big driving force for getting this in sooner rather than later is the saved memory on ethernet packets (and IP packets soon), that used to have file_scope() proto data when all it needed was packet_scope() data (technically packet_info->pool scoped), strictly for Decode As.
All dissectors that use p_add_proto_data() only for Decode As functionality have been converted to using packet_scope(). All other dissectors were converted to using file_scope() which was the original scope for "proto" data.

running atop TCP should be done on flows from one TCP endpoint to

We do this by:
adding "reassembly table" as a data structure;
associating hash tables for both in-progress reassemblies and
completed reassemblies with that data structure (currently, not
all reassemblies use the latter; they might keep completed
reassemblies in the first table);
having functions to create and destroy keys in that table;
offering standard routines for doing address-based and
address-and-port-based flow processing, so that dissectors not
needing their own specialized flow processing can just use them.
This fixes some mis-reassemblies of NIS YPSERV YPALL responses (where
the second YPALL response is processed as if it were a continuation of
a previous response between different endpoints, even though said
response is already reassembled), and also allows the DCE RPC-specific
stuff to be moved out of epan/reassembly.c into the DCE RPC dissector.

The reassembled fragments tree in the Packet Details view is awesome, but it
lacks one thing: a field that exposes the reassembled data.
tcp.data already exists for exposing a single TCP segment's payload as a byte
array. It would be handy to have something similar for a single application
layer PDU when TCP segment reassembly is involved. I propose
tcp.reassembled.data, named and placed after the already existing field
tcp.reassembled.length.
My primary use case for this feature is outputting tcp.reassembled.data with
tshark for further processing with a script.
The attached patch implements this very feature. Because the reassembled
fragment tree code is general purpose, i.e. not specific to just TCP, any
dissector that relies upon it can add a similar field very cheaply. In that
vein I've also implemented ip.reassembled.data and ipv6.reassembled.data, which
expose reassembled fragment data as a single byte stream for IPv4 and IPv6,
respectively. All other protocols that use the reassembly code have been left
alone, other than inserting NULL into their initializer lists for the newly
introduced struct field reassemble.h:fragment_items.hf_reassembled_data.
