* Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer2002-08-021-8/+4
| | | | | | | | 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. svn path=/trunk/; revision=5932
* Include files from the "epan" directory and subdirectories thereof withGuy Harris2002-01-211-2/+2
| | | | | | | | | | | | | "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/"). svn path=/trunk/; revision=4586
* Move the pointer to the "column_info" structure in the "frame_data"Guy Harris2001-12-101-9/+9
| | | | | | | | | | | | | | | 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. svn path=/trunk/; revision=4370
* Attach a descriptive name field type and base to dissector tables; thatGuy Harris2001-12-081-2/+3
| | | | | | | | | | | | | | specifies how the selector values used as keys in those tables are to be displayed, and the title to use when displaying the table. Use that information in the code to display the initial and current entries of various dissector tables. Have the dissector for BACnet APDUs register itself by name, and have the BACnet NPDU dissector call it iff the BAC_CONTROL_NET bit isn't set, rather than doing it with a dissector table. svn path=/trunk/; revision=4358
* Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris2001-12-031-6/+8

* An NLPID of 1 means T.70 when used as an X.263/ISO 9577 initial protocolGuy Harris2001-12-021-2/+10
| | | | | | | | | | | | | | | | | | | | identifier, but means X.29 when used as an X.263/ISO 9577 secondary protocol identifier. Add support for the IPv6 NLPID, and Ethernet type, in more places. Fix up the handling of the user data of a CALL REQUEST packet to more correctly distinguish between user data containing an NLPID and user data containing an X.264/ISO 11570 UN TPDU. If it's an NLPID, use "nlpid_vals" to show its value. Put that user data in a subtree. Create a new "x.25.spi" dissector table, for protocols running atop X.25, rather than having a built-in switch statement, so that other protocols can register themselves by NLPID. svn path=/trunk/; revision=4300

* NLPID's of 0x08 and 0x09 should be labeled as Q.933 and LMI,Guy Harris2001-03-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | respectively, not Q.931 and Q.2931, in Frame Relay. When dissecting Q.933-style multiprotocol encapsulated Frame Relay frames, use the "osinl" dissector table to check for OSI network layer protocols, include the NLPID in the tvbuff you hand to "dissector_try_port()" with that dissector table, and put the NLPID into the protocol tree as an invisible item - the NLPID is considered part of the PDU for those protocols, so you have to include it in the tvbuff, and the dissector will put it into the protocol tree. Also, make sure the top-level entry for the Frame Relay protocol includes all the bytes preceding the payload, and none of the payload bytes. Export a routine to do Q.933-style dissection, and have the WCP dissector call it, rather than duplicating that code in the WCP dissector. Don't register OSI network layer protocols with the "fr.ietf" dissector table; it's now sufficient to register them with the "osinl" dissector table, as the Frame Relay dissector now checks that. Get rid of unnecessary checks for protocols being enabled (if the dissector is always called through handles or dissector tables, the common code for handles and dissector tables will do the checks for you). Get rid of some unnecessary #includes. svn path=/trunk/; revision=3211
* Add WCP to the list of Ethernet types in "etype_vals[]", and addGuy Harris2001-03-291-1/+2
| | | | | | | | "compressed" to the list of NLPIDs in "nlpid_vals[]". Use "nlpid_vals" for the Frame Relay NLPID field. svn path=/trunk/; revision=3206
* Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris2001-01-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | "{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....) svn path=/trunk/; revision=2849
* For each column, have both a buffer into which strings for that columnGuy Harris2000-11-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. svn path=/trunk/; revision=2670
* Register the OSI transport dissector by name, and make it static.Guy Harris2000-11-191-2/+1
| | | | | | | | | "packet-clnp.h" no longer exports anything, so remove it. Have the X.25 dissector call subdissectors through dissector handles (now that all the dissectors it uses are registered by name). svn path=/trunk/; revision=2668
* Tvbuffify the IP, ICMP, TCP, UDP, OSI CLNP, OSI COTP, OSI CLTP, and OSIGuy Harris2000-11-181-25/+34
| | | | | | | | | | | | | | | | | | | | | | ESIS dissectors. Register the IP dissector and have dissectors that call it directly (rather than through a port table) call it through a handle. Add a routine "tvb_set_reported_length()" which a dissector can use if it was handed a tvbuff that contains more data than is actually in its part of the packet - for example, handing a padded Ethernet frame to IP; the routine sets the reported length of the tvbuff (and also adjusts the actual length, as appropriate). Then use it in IP. Given that, "ethertype()" can determine how much of the Ethernet frame was actually part of an IP datagram (and can do the same for other protocols under Ethernet that use "tvb_set_reported_length()"; have it return the actual length, and have "dissect_eth()" and "dissect_vlan()" use that to mark trailer data in Ethernet II frames as well as in 802.3 frames. svn path=/trunk/; revision=2658
* Give the "null" link-layer header dissector a dissector table, and putGuy Harris2000-11-171-1/+3
| | | | | | | the BSD AF_ type values it uses into an "aftypes.h" header file for dissectors that register themselves in that dissector table include. svn path=/trunk/; revision=2653
* Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris2000-08-071-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dissectors to be registered as dissectors for particular ports, registered as heuristic dissectors, and registered as dissectors for conversations, and have routines to be used both by old-style and new-style dissectors to call registered dissectors. Have the code that calls those dissectors translate the arguments as necessary. (For conversation dissectors, replace "find_conversation_dissector()", which just returns a pointer to the dissector, with "old_try_conversation_dissector()" and "try_conversation_dissector()", which actually call the dissector, so that there's a single place at which we can do that translation. Also make "dissector_lookup()" static and, instead of calling it and, if it returns a non-null pointer, calling that dissector, just use "old_dissector_try_port()" or "dissector_try_port()", for the same reason.) This allows some dissectors that took old-style arguments and immediately translated them to new-style arguments to just take new-style arguments; make them do so. It also allows some new-style dissectors not to have to translate arguments before calling routines to look up and call dissectors; make them not do so. Get rid of checks for too-short frames in new-style dissectors - the tvbuff code does those checks for you. Give the routines to register old-style dissectors, and to call dissectors from old-style dissectors, names beginning with "old_", with the routines for new-style dissectors not having the "old_". Update the dissectors that use those routines appropriately. Rename "dissect_data()" to "old_dissect_data()", and "dissect_data_tvb()" to "dissect_data()". svn path=/trunk/; revision=2218
* Register an "osinl" dissector table for ISO/IEC TR 9577 NLPID values,Guy Harris2000-04-171-11/+16
| | | | | | | | | | and have dissectors for protocols that run at the OSI network layer register themselves with it using "dissector_add()". Make various dissectors static if they can be, and remove from header files declarations of those dissectors. svn path=/trunk/; revision=1873

* In the COTP dissector, don't forcibly set the protocol to COTP if weGuy Harris2000-04-151-7/+10
| | | | | | | | find a COTP PDU - we might have called a subdissector, which would have set the protocol itself. Do so only if we've not seen any DT PDUs on which we've called a subdissector. svn path=/trunk/; revision=1864
* Alas, one can't count on CLNP packets with a destination NSEL of 0x21Guy Harris2000-04-151-17/+31
| | | | | | | | | | | being COTP packets, so we make "dissect_cotp_internal()" return FALSE if it saw no valid COTP packets, and return TRUE and set the COL_PROTOCOL field to COTP if it saw at least one valid COTP packet, and have "dissect_cotp()" dissect the packet as raw data if "dissect_cotp_internal()" returns FALSE (for the benefit of callers such as X.25). svn path=/trunk/; revision=1861
* If an NPDU contains multiple concatenated TPDUs, dissect all of them.Guy Harris2000-04-151-102/+125
| | | | | | | | | | | Fix up some spacing problems in the INFO field of CLNP packets. Dissect only the payload of DT and MD NPDUs as COTP; the payload of other packets isn't to be so dissected (ER NPDUs are like ICMP error packets, in that they contain the network-layer header and zero or more bytes of the payload of the offending packet, for example). svn path=/trunk/; revision=1860
* Set the COL_PROTOCOL column to "ISIS" in the ISIS dissector, rather thanGuy Harris2000-04-131-26/+15
| | | | | | | | | | | | | | in its caller. Set the COL_PROTOCOL column to "COTP" in the COTP dissector, rather than in the dissectors it calls, so that it's done for all frames we hand to that dissector. Set the COL_INFO field for COTP packets we don't dissect because the length indicator is zero, or the frame is too short, or the PDU type is bogus. svn path=/trunk/; revision=1842
* Add CLNP PDU types other than DT and ER.Guy Harris2000-04-131-30/+84
| | | | | | | | | | | | | Fix the TPDU code numeric value to be "0x%x" rather than "Ox%x". Add a COL_INFO field for CLNP PDUs whose payload we don't dissect as COTP. Don't dissect segments other than the first derived PDU of a segmented CLNP PDU (just as we do with fragments other than the first fragment of a fragmented IP datagram). svn path=/trunk/; revision=1841
* Fix a typo.Guy Harris2000-04-131-43/+56
| | | | | | | | | | Use "%u" rather than a hex format to print length values and segment offsets, and use "%u" rather than "%d" to print unsigned values. In the CLNP dissector, chop off the payload and captured-payload lengths based on the segment length (along the lines of what we do for IP). svn path=/trunk/; revision=1839
* Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez2000-03-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | proto_tree_add_protocol_format() proto_tree_add_uint_format() proto_tree_add_ipxnet_format() proto_tree_add_ipv4_format() proto_tree_add_ipv6_format() proto_tree_add_bytes_format() proto_tree_add_string_format() proto_tree_add_ether_format() proto_tree_add_time_format() proto_tree_add_double_format() proto_tree_add_boolean_format() If using GCC 2.x, we can check the print-format against the variable args passed in. Regardless of compiler, we can now check at run-time that the field type passed into the function corresponds to what that function expects (FT_UINT, FT_BOOLEAN, etc.) Note that proto_tree_add_protocol_format() does not require a value field, since the value of a protocol is always NULL. It's more intuitive w/o the vestigial argument. Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*) Checked in Guy's fix for the function declearation for proto_tree_add_text() and proto_tree_add_notext(). svn path=/trunk/; revision=1713
