Moshe Kaplan 20c57cb298 Enable exporting objects with tshark
A new "--export-object <protocol>,<destdir>" option is added to tshark.

This required refactoring Export Object behavior in all GUIs to give the
export object handling to the dissector, rather than the ui layer.
Included in the refactoring was fixing some serious memory leaks in Qt
Export Object dialog, crash due to memory scope issues in GTK Export
Object dialog, and addition sorting column feature in Qt dialog (set
up by creating a widget to manage the items that were previously
leaking memory)

John A. Thacker da7354a636 Fragmentation reassembly as in PPP MP (RFC 1990/2686)
Add support for defragmentation of fragments that use the defragmentation
scheme of PPP MP (RFC 1990). Instead of getting "sequence_number,
fragment_number, last" as in other protocols, PPP MP provides a single
sequence number that is effectively "seqnum + fragnum", though it provides
flags for both the first and last fragment of a reassembly.

See Appendix A of RFC 4623 (PWE3 Fragmentation and Reassembly) for a list
of protocols that use this style, including PPP MP (RFC 1990), PWE3 MPLS
(RFC 4385), L2TPv2 (RFC 2661), L2TPv3 (RFC 3931), ATM, and Frame Relay.

Also add support for the Multi-class Extension to Multilink PPP (RFC 2686),
which uses some of the previously reserved bits as classes that distinguish
otherwise identical sequence numbers.

Michael Mann 268841f3e0 Combine Decode As and port preferences for tcp.port dissector table.
This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table.  It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.

The tcp.port dissector table was used as the guinea pig.  This will eventually be
expanded to other dissector tables as well (most notably UDP ports).  Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.

Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference

Also added comments for TCP ports used that aren't IANA registered.

Guy Harris a4c8ebc18b Don't do any Decode As stuff for dissector tables not used with Decode As.
Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.

When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.

For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.

This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.

The proto tree is needed in several cases when using Lua field extractors,
because they fetch values from the tree.  Without a valid field extractor
a Lua plugin may misbehave and display wrong column info.

This fixes column issues when:
- Calling resetColumns() in Qt.  This involves adding a display filter,
  change time display format, change name resolution and other changes
  in UI which requires column updates.
- Print summary lines.
- Export as CSV and PSML.

Guy Harris c599cd7b0b Add proto_tree_add_item_ret_string() routine.
It adds string-type fields to the protocol tree and returns the value of
the string.

Add the new bitmask-adding routines to the Debian symbol list while
we're at it.

Michael Mann c62547b951 Refactor "Follow Stream" functionality on all GUI interfaces.
Create a "registration" system for Follow functionality so most of the work can be abstracted into a dissector and GUI can just be responsible for "display".
This also removes the global variables in follow.c to open up multithreading possibilities.

TCP, UDP and HTTP all have the same "tap interface" for Follow functionality (passing a tvb with byte data to "follow"). SSL still has it's own behavior, so Follow structures have to take that into account.

TShark through the Follow registration now has support for HTTP.

The only thing possibly missing is dynamic menu generation to further reduce explicit knowledge of Follow "type" (and rely on registration)

Guy Harris c67c6e8f30 Add routines to add an item and return the item's real length.
proto_item_get_len() is *not* guaranteed to return a correct value.
Even if there's a non-null tree item, it might be pointing to a "faked"
item; it really shouldn't be used.

So add proto_tree_add_item_ret_length() and
proto_tree_add_item_new_ret_length(), which calculate the real length
themselves and return it through a pointer.

Fix as many places as we straightforwardly can to use them rather than
to use proto_item_get_len().  (There's a Lua API for
proto_item_get_len(), so we keep it around, but we should add Lua APIs
for the new routines, and deprecate the old API.)

Fix ptvcursor_add() to do the same thing that
proto_tree_add_item_ret_length() and
proto_tree_add_item_new_ret_length() do.

Split the TRY_TO_FAKE_THIS_ITEM macros into a macro to check for the
tree being null and to try to fake the item.  We don't always use the
former macro, as we might need to do more than just return NULL if the
incoming tree is null (for example, calculating the item's real length
and using it...).

new_field_info() never returns NULL; remove checks for it.  The check
for a null tree is done before the calls to new_field_info().

Michael Mann 57acc227f0 KISS the Follow TCP functionality.
[KISS - Keep It Simple, Stupid]
Convert the Follow TCP functionality to use a tap from the TCP dissector that passes the tvb of the payload.  This makes things A LOT simpler, but relies on the TCP dissector to make all decisions.
The "tap" logic passes tvb data
1. Before calls to process_tcp_payload
2. Before hf_tcp_segment_data fields (that aren't retransmissions or otherwise handled)

Follow up patches will be necessary to clean up all of the supporting "follow" functionality that is now useless.

Guy Harris cdf9943717 Don't walk the entire protocol tree to extract the value of one field.
Instead, prime the epan_dissect_t's tree to look for rtp.ssrc, and
extract that value with proto_get_finfo_ptr_array().

Also, have the filter used to check whether the packet is a candidate
for RTP analysis to check for RTPv2 (and add a check for IPv4 or IPv6
back to the Qt version), and get rid of an unnecessary extra level of
indirection for that string.

In the Qt version, if findStreams() set the error string, don't
overwrite it with a "No streams found." indication, and fix error
handling for the "filter didn't compile" case.

Michael Mann 56aa05227f Create a way to register "capture" dissectors.
Capture dissectors could be architected like dissection dissectors, with tables and subtables and possibly using tvbs to pass there data instead of raw byte arrays.  This is a first step towards that by refactoring capture_info_packet() to work off of a "capture dissector table"

Registering the capture dissection functions instead of calling them directly also clears up a bunch of dissector header files who sole purpose was providing the capture dissection function definition.
