Wasim Abu Moch 401469880b packet-erf: added dissector table for "erf.types.type" type field.
1- removed unnecessary include <wiretap/erf.h>
2- used fall through in protocol switch case instead of calling same
function with same params.

fixes/changes after review with Evan Huus, changes ETH/IPv4/IPv6/Infiniband/InfinibandLink
to use dissector table instead of direct function calls.
other protocols should be called in the same way, we'll do it when have
the time.

instead of calling subdissector directly from packet-erf.c code it's
easier to declare this and each time we need to register a new
protocol over erf format we sould easily extend it from the protcol module
instead using "dissector_add_uint()" function.

the change is still backward compatible, if no upper protocol is
registered for the specifc type an old fasion direct function call
is performed.

Michael Mann 018b84de84 Refactor "common" hostlist/endpoint table functionality.
This is very similar in architecture to the changes made to the Conversation table functionality.  Since all conversations have endpoints/hostlists, the "registered" list is shared for both.

Guy Harris ebff85fdbb Clean up Internet checksum handling.
Add macros to set entries of a vec_t, one for use when you have a
pointer to private data, and one for use when you have data in a tvbuff.
The latter wraps the use of tvb_get_ptr(), so that you're not directly
calling it in a dissector.

Move ip_checksum() to epan/in_cksum.c, and add an ip_checksum_tvb() that
wraps the use of tvb_get_ptr().

In the CARP dissector, give the length variable an unsigned type -
there's no benefit to it being signed, and that requires some casts to
be thrown around.

In the DCCP dissector, check only against the coverage length to see if
we have enough data, combine the "should we check the checksum?" check
with the "*can* we check the checksum?" check in a single if, and throw
a dissector assertion if the source network address type isn't IPv4 or
IPv6.

Get rid of inclues of <epan/in_cksum.h> in dissectors that don't use any
of the Internet checksum routines.

In the HIP dissector, make sure we have the data to calculate the
checksum before doing so.

Michael Mann 76ab93ea94 Provide "Decode As" functionality through dissectors themselves instead of the GUI. Bug 9450 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9450)
The basic idea behind this design is to have dissectors register with a "decode as list" with their name and dissector table.  When "Decode As" dialog is launched, any "registered" dissector found in the packet will cause a tab to be created in the dialog.

This patch includes just the dissector portion of the functionality (minus packet-dcerpc.[ch] because it has hooks to the current GUI)

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.

Michael Mann b38ee917b1 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 done with a perl script on the dissectors directory (packet-*.c), followed by manual inspection of the output. The manual inspection yielded a few cases that really should have been proto_tree_add_uint or proto_tree_add_item, so I updated them accordingly.
The script didn't catch as many as I would have liked, but it's a start.

The most common (ab)use of proto_tree_add_uint_format was for appending strings to CRC/checksum values to note good or bad CRC/checksum.

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.

Constify a bunch of variables, parameters, and return values to

us to do so.

Enable a bunch of additional warnings by default.  Note why at least
some of the other warnings aren't enabled.

randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.

If the user specifies --enable-warnings-as-errors, add -Werror *even if

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.
