frame number, which is always decimal. If you select an FT_FRAMENUM
field, there are menu items that let you go to the frame whose frame
number appears in that field.
Add FT_FRAMENUM fields for the ONC RPC "matching request is in this
frame" and "matching reply is in this frame" protocol tree items.

often get TCP to collapse multiple RPC PDUs into a MSS TCP segment.
This changes the RPC dissector so that it will put one entry on COL_INFO
for each PDU in the segment, (as the SMB dissector does for multiple AndX calls in one SMB PDU)
and just one entry for the first/last RPC PDU.

Use "guint8", not "guchar", for a pointer to (one or more) 8-bit bytes.

dissect_rpc_opaque_data() the actual bytes into the dissector data tree
(improves searching). But if we only give the string "<DATA>" to the
proto_tree_add_* functions and tell it at the same time, that we have indeed
string_length_copy bytes, this leads to problems.
Correction: give the pointer into the real data and not the pointer to the
print string to the proto_tree_add_string_format() and
proto_tree_add_bytes_format() functions.
The correction was found by Martin Regner.

sequence numbers or offsets and are thus assumed to be received in order
with no duplicates or dropped fragments (e.g., for NetBIOS Frame, where
802.2 LLC guarantees in-order delivery to NetBIOS with no duplicates or
dropped fragments).
"show_fragment_tree()' and "show_fragment_seq_tree()" don't modify the
"fragment_items" to which the "fit" argument points, so make that
argument a "const fragment_items *".
Make all the "fragment_items" tables "static" (as they're not used
outside the modules defining them) and "const" (as they're not
modified).
Add support for reassembly of NetBIOS fragmented requests and responses.
Get rid of an unnecessary include of "packet-tr.c" in the NetBIOS
dissector, and make its table of dissection function pointers static.
Fix some typos in the AppleTalk and NetBIOS dissectors.

value for a field to be used for the procedure number for that version
of the protocol; use that field, if specified, instead of just putting
in a generic "rpc.procedure" field.
Have the ypserv dissector register those fields and supply them to
"rpc_init_proc_table()". Supply -1 for other RPC programs (for now),
meaning "no such field exists".

One example extension is rpcstat.
Try -Z rpc,rtt,100003,3 as argument to tethereal when reading a capture
containing NFSv3 packets.
tap-rpcstat.[ch] is intended to demonstrate the api and can be used to
base other extensions on.

but for stuff reassembled with "fragment_add_seq()" or
"fragment_add_seq_check()".
Add a "fragment tag" string to the "fragment_items", so that packets
with fragmentation errors can be properly flagged as having "Illegal
fragments" or "Illegal segments" depending on the term used with the
protocol in question.
Make all the dissectors that can use "show_fragment_tree()" or
"show_fragment_seq_tree()", and don't already use them, do so.

When this ption is enabled in Protocols/NFS displayfilters for fhandle fields
such as nfs.fh.{hash|name|full_name} will find both the request and matching
response packets even if the fhandle is only present in one of the packets.
The option supports all NFS and related protocols which use nfs fhandles
including async NLM.
The option will not work with nfs packets containing multiple fhandles in
one PDU, nor will it work if tcp collapses multiple segments/pdus into
one larger segment.
It only works for async NLM if one first enables the MSG/RES stateful
matching for async NLM.

protocol reply if:
we got anything other than SUCCESS for MSG_ACCEPTED;
we got MSG_DENIED;
we got anything other than MSG_ACCEPTED or MSG_DENIED;
as there isn't a protocol reply in there.
Just use "-1, -1" as arguments to "tvb_new_subset()" if you want the new
tvbuff to run to the end of the packet - there's no need to call
"tvb_reported_length_remaining()".

When we see PRTOMAP GETPORT calls for UDP, make sure all further UDP packets to or from
this port goes to the ONC-RPC dissector regardless of the port on the other side.
We need this because if there is ONC-RPC traffic going between the ONC-RPC Program port to a port which has a normal ethereal dissector, ethereal would dissect the traffic as the protocol associated with the other port instead.

RPC and NDMP.
Show the RPC-over-TCP fragment header as a tree with bitfields below it.
Add a routine to show a reported bounds error as an "Unreassembled
Packet" or a "Malformed Packet" depending on whether "pinfo->fragmented"
is set, and have NBNS and RPC use that.
Add "ett_ndmp_file_stats" to the list of ett_ values to be initialized
(it wasn't in that list, and wasn't getting initialized).
When freeing up various hash tables and memory chunks in the RPC
dissector, zero out the pointers to them, just to make sure we don't try
to free them again.
Always destroy the TCP segment key and address memory chunks in
"tcp_desegment_init()", regardless of whether TCP desegmentation is
enabled - we don't *allocate* them if TCP desegmentation isn't enabled,
but we should free them even if it's not enabled. Also, when we free
them, set the pointers to them to null, so we don't double-free them.
Supply to subdissectors called from the TCP dissector the sequence
number of the first byte handed to the sub dissector.

"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/").

items to the protocol tree; it's interpreted as "the rest of the data in
the tvbuff". This can be used if
1) the item covers the entire packet or the remaining payload in
the packet
or
2) the item's length won't be known until it's dissected, and
will be then set with "proto_item_set_len()" - if an
exception is thrown in the dissection, it means the item ran
*past* the end of the tvbuff, so saying it runs to the end of
the tvbuff is reasonable.
Convert a number of "proto_tree_add_XXX()" calls using
"tvb_length_remaining()", values derived from the result of
"tvb_length()", or 0 (in the case of items whose length is unknown) to
use -1 instead (using 0 means that if an exception is thrown, selecting
the item highlights nothing; using -1 means it highlights all the data
for that item that's available).
In some places where "tvb_length()" or "tvb_length_remaining()" was used
to determine how large a packet is, use "tvb_reported_length()" or
"tvb_reported_length_remaining()", instead - the first two calls
indicate how much captured data was in the packet, the latter two calls
indicate how large the packet actually was (and the fact that using the
latter could cause BoundsError exceptions to be thrown is a feature - if
such an exception is thrown, the frame really *was* short, and it should
be tagged as such).
Replace some "proto_tree_add_XXX()" calls with equivalent
"proto_tree_add_item()" calls.
Fix some indentation.

get rid of some dead code;
get rid of some unnecessary initializations of variables that
are set in all code paths;
get rid of some set-but-not-used variables;

mark the frame, after putting in the item for the truncated
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.

than a pointer to a dissector function, as an argument.
This means that the conversation dissector is called through
"call_dissector()", so the dissector itself doesn't have to worry about
checking whether the protocol is enabled or setting
"pinfo->current_proto", so get rid of the code that does that in
conversation dissectors. Also, make the conversation dissectors static.
Get rid of some direct calls to dissectors; replace them with calls
through handles, and, again, get rid of code to check whether a protocol
is enabled and set "pinfo->current_proto" where that code isn't needed.
Make those dissectors static if they aren't already static.
Add a routine "create_dissector_handle()" to create a dissector handle
without registering it by name, if the dissector isn't used outside the
module in which it's defined.

Make the default for NBSS and ONC RPC-over-TCP desegmentation "on",
rather than "off"; the default for desegmentation in general is "off",
so this won't change the default behavior, but it lets you turn
desegmentation on by flipping only one switch (and turn it off for
particular protocols if you desire).

dissectors to use it, from Ronnie Sahlberg, with additional changes to
handle the case where a frame contains messages that don't run past the
end followed by one that does and where a reassembled chunk has, at the
end, a message that runs past the end of that chunk (because the
reassembly was for an earlier message).

source and destination addresses if the transport is TCP (we use that,
for now, as a proxy for "if the transport is connection-oriented"), as
the endpoint addresses should be the same for all packets.
Have both a heuristic RPC dissector and a non-heuristic version, and
make the non-heuristic version the dissector for the conversations we
create; that version will, if the frame doesn't look like a call or
reply, mark it as continuation data.

of protocol-id-plus-datum pairs, so that multiple protocols can attach

that if they find a conversation it has one of its data attached to it;

This lets us get some more work done on short frames (although if you
really want to analyze ONC RPC traffic, you should make the snapshot
length large enough to capture enough of the frames).
