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.

Add support for 11R RIC IE's: Data and Descriptors for both FT-Over-Air and FT-Over-DS
Add 802.11 Tag RIC Data (57)
Add 802.11 Tag RIC Descriptor (75) (Not tested...)
From me:
- Remove tabs and whitespace
- Fix fix-encodings-args "warning"
svn path=/trunk/; revision=48421
Needed to convert use of old IEEE802.11 preference strings to UAT. Since UAT is self-contained within its own file, the entire preference file doesn't need to be rewritten/saved when UAT values are changed.

Need to add support for WAPI parameter set IE in management frames.
We already have WAI frames dissection support in place.
From me:
Small changes...
- Add links to WAPI specs
- Replace tabs by space
- Remove whitespaces

If we don't decode a tag, just say "Undecoded" on the top-level item;
the tag name or number is already on that item, and the length is
underneath it.

In the array of WME AC names, the name for tid 3 is wrongly named as "Video" it should be "Best Effort" instead.

epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

If the SSID isn't valid UTF-8 truncate it and indicate that we did so.
(As bug 5738 points out this is part of a more general problem but in
the meantime this keeps us from crashing.)
Don't try to decrypt too-long SSIDs.
I feel compelled to change my SSID at home to a series of carriage
returns, linefeeds, and SNOWMAN (U+2603).

Minor corrections to the VHT IE decode
* Correct the Rx, Tx and Basic MCS map decodes. The number of Spatial streams should run from 1-8 (not 0-7).
* Change Several misstyped Mhz into MHz
From me:
Remove comma for big number (use space)
Add Octets unit in some hf description
svn path=/trunk/; revision=47858
In some cases these malformed frames trigger a DISSECTOR_ASSERT() in proto.c's proto_item_set_len(). This happens when packet-ieee80211.c's dissect_ieee80211_mgt() calls packet-ieee80211.c's get_tagged_parameter_tree() with a "size" parameter value of -1.
From me:
Replace by proto_tree_add_item with -1 length (and use FT_NONE ftype)
svn path=/trunk/; revision=47795
and a couple of SET_ADDRESS()s.
Use proto_tree_add_item() instead of proto_tree_add_ether() called with a
pointer into the TVB.
Leave a comment for a place where a bunch of code in several case statements
could probably be collapsed into much less code.

- Use/create extended value strings as appropriate;
- Reformat hf[] entries;
- Do whitespace, & etc changes to use a consistent formatting style;
- Reformat some long lines;
- Localize some variables; remove some unneeded initializers;
- expert...() shouldnt be called under 'if (tree)' (packet-wimaxasncp);
- Move proto_register...() & etc to the end of the file (packet-ieee80211);
- Misc.

are like the non-TVB versions except that they take a TVB and an offset
instead of (frequently) a pointer into the TVB.
Calling tvb_get_ptr() before modifying the rest of the fields should help fix
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7960 (though I can't
reproduce that problem).
Replace a bunch of calls like:
SET_ADDRESS(..., AT_XXX, length, tvb_get_ptr(tvb, offset, length));
with:
TVB_SET_ADDRESS(..., AT_XXX, tvb, offset, length);
