Anders Broman 3ab0c21cbc Introduce call dissector_try_port_new() to be used when no protocol entry is to be made in the protocols list. Used by asn2wrs dissectors to avoid multiple entrys as calls are made
multiple times for the same PDU.

Guy Harris 31cae6e4ef Require GLib 2.4 or later.
That means that G_GINT64_MODIFIER will be defined, so don't check
whether it's defined.

We don't use the PRI[douxX]64 macros, as we use the GLib print routines
and thus use G_GINT64_MODIFIER instead.  Get rid of the checks for
whether inttypes.h defines PRI[douxX]64; just check whether it exists at
all.

That means we don't set INTTYPES_H_DEFINES_FORMATS, so don't check for
it.

Guy Harris 1bc049906a Add some GCC warnings to the standard set, and add some others to the
--enable-extra-gcc-checks set.

If we turn on -pedantic, try turning on -Wno-long-long as well, so that
it's not *so* pedantic that it rejects the 64-bit integral data types
that we explicitly require.

Constify a bunch of stuff, and make some other changes, to get rid of
warnings.

Ronnie Sahlberg fcab322ada Some applications do very naughty things like reusing a port for a different protocol during different stages of an application cycle.
This is very naughty and will cause problems when we have assigned a dissector to a dynamic port using conversation_set_dissector().


To make ethereal handle this case I have changed the try_conversation_dissector() to allow it to fail and return 0,   meaning   yes there is indeed a protocol registered for this conversation but that protocol rejected this packet.
(which only happens for "new" style dissectors, "old" style dissectors will never reject a packet that way)

When this happens  the decode_udp_port() helper will still allow other dissectors to be tried, in the hope that the conversation is now used for some other protocol and thus someone else might be able to decode the packet.


Update SNMP and TFTP dissectors to  check that even if there already is a conversation but that conversation does NOT have snmp/tftp registered as the dissector for it, then create a new conversation anyway and attach the proper dissector.

Since ethereal keeps track of which frame number a conversation started in, this actually works really well.

Guy Harris d53df176c1 Add a "cleanup_dissection()" routine, intended to free up data
structures allocated by a dissection.  Currently, it's the same as
"init_dissection()", but they should be split with "init_dissection()"
allocating the initial data structures and "cleanup_dissection()"
freeing them and *not* reallocating the initial data structures.

Use "cleanup_dissection()" in "cf_close()" to make it easier to find leaks.

Guy Harris 8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Guy Harris 7002776572 Pick up the stuff I did for tcpdump to figure out the right strings to
use to format 64-bit integers.

Fix the RSVP dissector to use that rather than hardcoding "%ll" in.

Remove the "only if G_HAVE_GINT64 is defined" bit from the discussion of
64-bit integers - we're too dependent on having them to support
compilers that don't have a 64-bit integral data type.  Do, however,
note that neither "long" nor "long long" are acceptable, and also note
that you shouldn't assume "%ll" does the trick for printing them.

Guy Harris be2736adcf Have a pseudo-header for Ethernet packets, giving the size of the FCS -
0 means "there is no FCS in the packet data", 4 means "there is an FCS
in the packet data", -1 means "I don't know whether there's an FCS in
the packet data, guess based on the packet size".

Assume that Ethernet encapsulated inside other protocols has no FCS, by
having the "eth" dissector assume that (and not check for an Ethernet
pseudo-header).

Have "ethertype()" take an argument giving the FCS size; pass 0 when
appropriate.

Fix up Wiretap routines to set the pseudo-header.  This means we no
longer use the "generic" seek-and-read routine, so get rid of it.

Guy Harris c26004150b When registering a dissector table, choose what type of hash and
comparison function to use based on the type value passed in.  For the
traditional unsigned integer table, require FT_UINT{8,16,24,32}; if the
type is FT_STRING or FT_STRINGZ, use the string hashing functions
instead.

Add routines for manipulating entries and looking up dissectors in
string dissector tables.

Guy Harris f2233623ea From Lionel Ains: "-d" flag for decode-as support in Tethereal.
Add a new routine to iterate through all dissector tables, calling a
routine for each table, to support having the "-d" code list all
dissector tables.

Get rid of "dissector_handle_get_dissector_name()"; it was put in there
for "-d", but turns out not to be necessary for that.

Clean up the usage message a bit (using the convention, adhered to by at
least some UNIX utilities, of listing all the flags with no arguments in
a single lump, and then listing the ones with arguments individually,
and also putting "-v" and "-h" in a separate lump, as Ethereal does).

Gilbert Ramirez 41cc7f0707 Merge the work in Novell_NCP_branch into the mainline code.
A little work still needs to be done on the new NCP dissector -- make
some of the COL_INFO texts more useful, handle a Unicode issue, and
modify some of the cases that use "request conditions".
But the NCP dissector as it stands is very usable now.

Note: I didn't merge in the PROTO_LENGTH_UNTIL_END macro... I wanted
to think about the various possible macros and review an email conversation
I had with Guy on the subject.

Guy Harris db119f15d4 Add routines to create anonymous handles for new-style dissectors (ones

dissect, or 0, meaning "this isn't one of my packets").

Guy Harris 193b8c9bfb Allow dissectors to be registered as "old-style" or "new-style"
dissectors.  "Old-style" dissectors return nothing.  "New-style"
dissectors return one of:

	a positive integer, giving the number of bytes worth of data in
	the tvbuff that it considered to be part of the PDU in the
	tvbuff;

	zero, if it didn't consider the data in the tvbuff to be a PDU
	for its protocol;

	a negative integer, giving the number of additional bytes worth
	of data in needs to get the complete PDU (for use with
	fragmentation/segmentation when the length of the PDU isn't
	known to the protocol atop the one the dissector is dissecting).

Have "call_dissector()" return the return value of new-style dissectors,
and the length of the tvbuff handed to it for old-style dissectors.

Have "dissector_try_port()" return FALSE if the subdissector is a
new-style dissector and returned 0.

Make the EAP dissector a new-style dissector, and have a "EAP fragment"
dissector that is also a new-style dissector and handles fragmentation
of EAP messages (as happens above, for example, RADIUS).  Also, clean up
some signed vs. unsigned comparison problems.

Reassemble EAP-Message AVPs in RADIUS.

Guy Harris 6a21dc7e44 Don't give tvbuffs names; instead, give data sources names, where a
"data source" has a name and a top-level tvbuff, and frames can have a
list of data sources associated with them.

Use the tvbuff pointer to determine which data source is the data source
for a given field; this means we don't have to worry about multiple data
sources with the same name - the only thing the name does is label the
notebook tab for the display of the data source, and label the hex dump
of the data source in print/Tethereal output.

Clean up a bunch of things discovered in the process of doing the above.
