Guy Harris 3c1508a6b3 Fix Gerald's e-mail address - and fix it in "README.developer", so
people don't blindly insert the old address into new dissectors, which
is probably how it got into the dissectors being fixed here.

Guy Harris 29f1d4b093 Don't attempt to modify the data pointed to by the result of
"tvb_get_ptr()".

Display a "(B)" flag for supported rates that are in the BSSBasicRate
Set.

Gilbert Ramirez 5664e5887f Make tvb_get_ptr() return 'const guint8*', and clean up all the
usages of tvb_get_ptr(). packet-ieee80211.c still has one bad usage,
in which it *does* modify the tvbuff's data.

Guy Harris 562eae009f Updates from Johan Jorgensen:
Correct number of addresses shown in dataframes.
	Duration ID changed to "Association ID" in power-save polls

Guy Harris 11d33ec712 Fix forwarded by Johan Jorgensen of Axis Communications.
Also, print unsigned quantities with %u, not %d.

Guy Harris d9718a693d Remove some more "CHECK_DISPLAY_AS_DATA()" calls and code to set
"pinfo->current_proto", in dissectors always called through dissector
tables and handles.

Make the IEEE 802.11 dissector static, as it's not called externally.

Clear the Info column in the Linux cooked capture and 802.1q VLAN
dissectors, before extracting anything from the packet, so that if an
exception is thrown, the Info column doesn't reflect the previous
protocol.

Don't extract the encapsulated protocol in the VLAN dissector until you
use it, so that if the frame contains the VLAN ID but not the
encapsulated protocol, we at least put the VLAN ID into the protocol
tree.

Guy Harris b6248efe1f The frame control field is, I infer from "dissect_ieee80211()",
little-endian, so "capture_ieee80211()" should use "pletohs()", not
"pntohs()", to fetch it.

Also, "pletohs()" takes a *pointer* to the object to be fetched as an
argument.

Guy Harris 43ccfd8054 Add an additional "protocol index" argument to "{old_}dissector_add()",
"{old_}heur_dissector_add()", "{old_}conv_dissector_add()", and
"register_dissector()", so that an entry in those tables has associated
with it the protocol index of the protocol the dissector handles (or -1,
if there is no protocol index for it).

This is for future use in a number of places.

(Arguably, "proto_register_protocol()" should take a dissector pointer
as an argument, but

	1) it'd have to handle both regular and heuristic dissectors;

	2) making it take either a "dissector_t" or a union of that and
	   a "heur_dissector_t" introduces some painful header-file
	   interdependencies

so I'm punting on that for now.  As with other Ethereal internal APIs,
these APIs are subject to change in the future, at least until Ethereal
1.0 comes out....)

Guy Harris b151ddecbb Have the TR MAC and LLC dissectors register themselves, make them
static, and have other dissectors call them through handles.

Guy Harris 0e7c1de08a Have "proto_register_protocol()" build a list of data structures for
protocols, in addition to adding structures to the list of filterable
fields.  Give it an extra argument that specifies a "short name" for the
protocol, for use in such places as

	pinfo->current_proto;

	the dialog box for constructing filters;

	the preferences tab for the protocol;

and so on (although we're not yet using it in all those places).

Make the preference name that appears in the preferences file and the
command line for the DIAMETER protocol "diameter", not "Diameter"; the
convention is that the name in question be all-lower-case.

Make some routines and variables that aren't exported static.

Update a comment in the ICP dissector to make it clear that the
dissector won't see fragments other than the first fragment of a
fragmented datagram.

Guy Harris 7c5cf7fee0 Rename "proto_reg_handoff_iee380211()"[sic] to
"proto_reg_handoff_wlan()", to match "proto_register_wlan()".

Call it "IEEE 802.11 wireless LAN", not "Wireless ethernet" - that makes
it clearer what type of wireless LAN it is (which *isn't* Ethernet at
the MAC layer, although I suspect many of the drivers make it look like
Ethernet to the rest of the system).

Gilbert Ramirez d673500082 Wrap the dissect_fddi() call (with a 4th argument) with
dissect_fddi_not_bitswapped() and dissect_fddi_bitswapped(), both of which
use the standard 3-argument tvbuffified-dissector argument list.

Add a dissector table called "wtap_encap" which is used to call dissectors
from dissect_frame(). The switch() statement from this top-level dissector
is removed.

The link-layer dissectors register themselves with the "wtap_encap"
dissector table. The dissectors are now static where possible.

Guy Harris 252d55d80f For each column, have both a buffer into which strings for that column
can be put, and a pointer to the string for the column, which might or
might not point to that buffer.

Add a routine "col_set_str()", which sets the string for the column to
the string passed to it as an argument; it should only be handed a
static string (a string constant would be ideal).  It doesn't do any
copying, so it's faster than "col_add_str()".

Make the routines that append to columns check whether the pointer to
the string for the column points to the buffer for the column and, if
not, copy the string for the column to the buffer for the column so that
you can append to it (so you can use "col_set_str()" and then use
"col_append_str()" or "col_append_fstr()").

Convert a bunch of "col_add_str()" calls that take a string constant as
an argument to "col_set_str()" calls.

Convert some "col_add_fstr()" calls that take a string constant as the
only argument - i.e., the format string doesn't have any "%" slots into
which to put strings for subsequent arguments to "col_set_str()" calls
(those calls are just like "col_add_str()" calls).

Replace an END_OF_FRAME reference in a tvbuffified dissector with a
"tvb_length(tvb)" call.

Guy Harris 2fa39ce7d3 Move the table of bit-swapped byte values to "epan/bitswap.c", and
declare it, and define a "BIT_SWAP" macro that uses it, in
"epan/bitswap.h".

Use that macro to bit-swap bytes in the IEEE 802.11 dissector, rather
than the macro that was used (said macro used GCCisms and didn't compile
on Windows).

Make an "init_plugin()" routine to enable a plugin and call its init
routine, and call it from "check_plugin_status()" and
"plugins_enable_cb()", rather than having very similar code in two
places; "patable" is now part of libethereal, and, at least on Windows,
attempts to refer to it from "libui" failed.  Make "patable" static to
"epan/plugins.c".  (This may still not work, as now "libui" is calling a
routine in "libethereal"; if that fails, perhaps it's time to get rid of
the "enable/disable plugins" stuff completely, as new-style plugins, at
least, register themselves as protocols and should be controllable from
the "Edit->Protocols" window just as built-in dissectors are.)

Guy Harris 7c3fcbac34 IEEE 802.11 support, from Johan Jorgensen of Axis Communications AB.
Add in stuff for a bunch of libpcap formats either in libpcap 0.5.2 or
in the current CVS version; we don't implement all of them in
Ethereal/Wiretap (those are "#if 0"ed out), but we do implement the IEEE
802.11 stuff (which isn't yet in libpcap or tcpdump, but the CVS version
of libpcap *does* reserve 105 as the encapsulation type number for
802.11).
