Jörg Mayer 173fe5aef4 Replace the types from sys/types.h and netinet/in.h by their glib.h
equivalents for the toplevel directory. The removal of winsock2.h will
hopefully not cause any problems under MSVC++, as those files using
struct timeval still include wtap.h, which still includes winsock2.h.

Guy Harris eb2d6593dc Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls in
arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls
that add FT_NONE or FT_PROTO items to the protocol tree, with -1.

Replace some calls to "tvb_length()" or "tvb_length_remaining()" with
calls to "tvb_reported_length()" and "tvb_reported_length_remaining()",
as those give the actual length of the data in the packet, not just the
data that happened to be captured.

Guy Harris ee5ca25d31 Include files from the "epan" directory and subdirectories thereof with
"epan/..." pathnames, so as to avoid collisions with header files in any
of the directories in which we look (e.g., "proto.h", as some other
package has its own "proto.h" file which it installs in the top-level
include directory).

Don't add "-I" flags to search "epan", as that's no longer necessary
(and we want includes of "epan" headers to fail if the "epan/" is left
out, so that we don't re-introduce includes lacking "epan/").

Guy Harris 23319ff023 Move the pointer to the "column_info" structure in the "frame_data"
structure to the "packet_info" structure; only stuff that's permanently
stored with each frame should be in the "frame_data" structure, and the
"column_info" structure is not guaranteed to hold the column values for
that frame at all times - it was only in the "frame_data" structure so
that it could be passed to dissectors, and, as all dissectors are now
passed a pointer to a "packet_info" structure, it could just as well be
put in the "packet_info" structure.

That saves memory, by shrinking the "frame_data" structure (there's one
of those per frame), and also lets us clean up the code a bit.

Guy Harris bced8711f6 Make "dissector_add()", "dissector_delete()", and "dissector_change()"
take a dissector handle as an argument, rather than a pointer to a
dissector function and a protocol ID.  Associate dissector handles with
dissector table entries.

Guy Harris 30c935a72e Use "proto_tree_add_item()", not "proto_tree_add_string()" with a
"tvb_get_ptr()" call using the same offset and length as the
"proto_tree_add_string()" call, to add FT_STRING fields to the tree.
(The value argument to "proto_tree_add_string()" must be
null-terminated, and there's no guarantee that the string you get from
the "tvb_get_ptr()" call will be null-terminated;
"proto_tree_add_item()" with an FT_STRING field, however, will
null-terminate the value.)

Fix the length argument in the call for the last item in the Yahoo
Messenger tree.

Guy Harris 0fa45bb541 FT_UINTn and FT_INTn fields must always have a base selected for them;
otherwise, the filtering GUI gets very upset when you try to construct a
filter expression to test the value of that field.  Make them BASE_DEC.

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 c57c848dfa Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="
statements.

Move the setting of the Protocol column in various dissectors before
anything is fetched from the packet, and also clear the Info column at
that point in those and some other dissectors, so that if an exception
is thrown, the columns don't reflect the previous protocol.

Don't use

	col_add_fstr(..., "%s", string);

Use

	col_add_str(..., string);

as it does the same thing, but doesn't drag all the heavy *printf
machinery in.

Fix the DDTP dissector to set the Info column regardless of whether
we're building a protocol tree or not, and to set it to "Encrypted
payload" if the payload is encrypted.  Also fix a typo in a field name.

Register the FTP data dissector as being associated with the FTP data
protocol, not the FTP protocol (the removed "CHECK_DISPLAY_AS_DATA()"
call checked "proto_ftp_data", and the removed "pinfo->current_proto ="
line set it to "FTP-DATA", so it should be associated with
"proto_ftp_data").

Make the H1 dissector check whether the frame has at least 2 bytes in it
before checking the first two bytes; heuristic dissectors must not throw
exceptions until they've accepted the packet as one of theirs.

Use "tvb_format_text()" rather than "tvb_get_ptr()" and "format_text()"
in some dissectors where the result of "tvb_get_ptr()" is used only in
the "format_text()" call.

In the Quake dissector, don't check whether there are at least 4 bytes
in the packet - if we return, the packet won't be dissected at all (it's
not as if some other dissector will get to handle it), and, if we don't
return, we'll throw an exception if there aren't at least 4 bytes in the
packet, so the packet will be marked as short or malformed, as
appropriate.

In the RIPng dissector, associate the table of strings for the command
field with the command field, so that the dissector doesn't have to
format the string for the protocol tree entry itself, and so that the
filter construction dialog box can let you select "Request" or
"Response" from a list rather than requiring you to know the values for
"Request" and "Response".

Make "dissect_rpc()" static, as it's called only through a heuristic
dissector list.

Use "col_set_str()" to set the COL_PROTOCOL column for RPC protocols;
the string used is from a table provided by the dissector, and is a
string constant.

Don't format the Info column for WSP into a buffer and then format that
buffer into the column with "%s" - "col_add_fstr()" can do the
formatting for you, without having to allocate your own buffer (or run
through the *printf machinery twice).

Don't fetch fields from the WTP packet until you're ready to use them,
so that you don't throw an exception before you even set the Protocol
column or clear the Info column.

Use "pinfo->destport", not "pi.destport", in the Zebra dissector when
checking whether the packet is a request or reply, and do the check by
comparing with "pinfo->match_port" rather than TCP_PORT_ZEBRA (so that
if the dissector is ever registered on another port, it still correctly
determines whether the packet is a request or reply - the Network
Monitor HTTP dissector has port 80 wired into its brain, which is a bit
irritating if you're trying to get it to dissect HTTP proxy traffic on
port 3128 or proxy administration UI traffic on port 3132).

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 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 0ab8e159b9 Some tvbuffified dissectors weren't setting "pinfo->current_proto", so
that if they threw an exception, the wrong protocol would be blamed.

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 c1214ede33 Use "memset()" to zero byte arrays, and "memcpy" to copy into them.
When copying IPv4 or IPv6 addresses, copy the minimum of the number of
bytes in the source and the destination, so that if the prefix length is
bogus, we don't overwrite the buffer.

"tvb_get_ptr()" returns a "guint8 *"; give the variable to which its
value is assigned that type.
