Peter Wu 80f7ee063d Call reassembly_table_destroy for some dissectors
This patch adds reassembly_table_destroy calls as cleanup function for
dissectors which have a simple init routine that just calls
reassembly_table_init (comments are ignored).

The changes were automatically generated using
https://git.lekensteyn.nl/peter/wireshark-notes/diff/one-off/cleanup-rewrite.py?id=4cc0aec05dc67a51926a045e1955b7a956757b5e
(with the if and assignment parsers disabled).

The only difference from the autogenerated output is that the XXX
comments from the init routines in smb-pipe and tds dissectors are kept.

Michael Mann 4497bb48fd Add address type registration.
Now address types are setup just like field types and must be registered with a structure that provides its string representation (and more things in the future).  Address types that are limited to a single dissector are registered by the dissector.  More "common" ones are globally registered.  There are still a few that really belong in a dissector, but have other dependencies currently not accounted for in the address type support.

Many of the "address to string" conversions that involved g_sprintf have be changed to use more "performance friendly" methods (some at the cost of needing to_str-int.h)

Leaving all comments regarding this "solution" in address_to_str.c in until all have been implemented

This allows dissector lists to be looked up by name, so they can be
shared by multiple dissectors.

(This means that there's no "udplite" heuristic dissector list, but
there shouldn't be one - protocols can run atop UDP or UDPLite equally
well, and they share a port namespace and uint dissector table, so they
should share a heuristic dissector table as well.)

Michael Mann 346f803d42 Convert proto_tree_add_uint_format to proto_tree_add_uint_format_value if hf_ field name is the first part of the formatted string. This was all manual inspection and most cases were either:
1. Case sensitivity differences between hf_ field name and formatted string.
2. Unnecessary whitespace between hf_ field name and colon in formatted string

There are cases where the hf_ field name doesn't quite match the proto_tree_add_uint_format, but it's close enough that one of them should be "right", I'm just not sure which is, I just know the string in proto_tree_add_uint_format is the one displayed.

Guy Harris 0efcd0632b When we're dissecting the beginning of a fragmented packet that we
haven't reassembled, we're probably moving sequentially through the
packet, which means that we'll run past the end of the fragment rather
than past the end of what would have been the reassembled packet had we
reassembled it.

I.e., there's little reason to care whether we're past the end of the
fragment but not past the end of the packet, or whether we're past the
end of the packet; in either case, we're past the end of the fragment,
and if somebody wants to know whether the packet is malformed by
stopping short of certain fields, they should enable reassembly.

So we get rid of the explicit fragment length in tvbuffs and, instead,
have a "this is a fragment" flag; if that flag is set, we throw
FragmentBoundsError rather than ReportedBoundsError if we run past the
end of the reported data.

(This also means we could flag the tvbuff even if we don't know how
large the reassembled packet will be, e.g. when doing IP reassembly.)

Replace tvb_new_subset_length_fragment() with tvb_new_subset_length()
and a new "set the "this is a fragment flag"" routine.

Guy Harris c0c15029ed Add to tvbuffs a "fragment length" field; if the tvbuff represents the
first fragment of a non-reassembled packet, and we know the length the
packet would have if it were reassembled, this field holds the length of
the fragment, and the "reported length" field shows the length the
packet would have if it were reassembled, so going past the end of the
fragment but staying within the length of the reassembled packet can be
reported as "dissection would have worked if the packet had been
reassembled" rather than "the packet is too short, so it was probably
malformed".

Add a FragmentBoundsError exception, thrown in the "dissection would
have worked if the packet had been reassembled" case.

Add a new tvb_new_subset_length_fragment() routine to create a new
subset tvb with specified fragment and reported lengths.  Use it in the

Guy Harris a2414d8909 Don't wire into the reassembly code the notion that reassemblies should
be done on flows from one address to another; reassembly for protocols
running atop TCP should be done on flows from one TCP endpoint to
another.

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.

Guy Harris 7ef91b394d Handle the pseudo-trailer for the ATN extended checksums by passing in
the source and destination address lengths and data, and adding them in,
rather than by copying those fields to a fixed-size static buffer - that
gets rid of a global variable (global variables considered harmful), and
also means that we don't try to copy 24 bytes of length+address from
packets that don't *have* 24 bytes of length+address (which caused
exceptions to be thrown on some OSI captures I have).

Construct some LI #defines out of other LI #defines, to make it a bit
clearer why they have the values they do.

Support the "additional information related to the clearing of the
connection" variable part parameter of the COTP DR packet (which just
means giving it a name, as its contents are user-defined - some HP-UX
OSI stack appears to just stick in a string saying that it's said
stack).

Make the code that decodes the variable part of a DR packet look like
the code that decodes the variable part of most other packets.

For COTP CR packets, determine the class up front by checking whether
the length is > 2.  (At some point we might want to associate a class
indication with the COTP connection, if we see the connection setup,
and, if we have that indication, use it in preference to the
heuristics.)

Make the code to handle various length indicator values in the ATN case
more like the code in the non-ATN case.

Jeff Morriss aa5d9d78dd From Robert Bullen via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7683 :
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.
