2000-11-15IEEE 802.11 support, from Johan Jorgensen of Axis Communications AB.Guy Harris11-10/+1848
Add in stuff for a bunch of libpcap formats either in libpcap 0.5.2 or in the current CVS version; we don't implement all of them in Ethereal/Wiretap (those are "#if 0"ed out), but we do implement the IEEE 802.11 stuff (which isn't yet in libpcap or tcpdump, but the CVS version of libpcap *does* reserve 105 as the encapsulation type number for 802.11). svn path=/trunk/; revision=2646
2000-11-14Add a ; to the empty default case in a switch statement. ANSI C saysGilbert Ramirez1-1/+3
you need some statement there, and a semicolon serves as a statement. Put a comment in there too, emphasizing the fact that the default case was meant to be empty. svn path=/trunk/; revision=2645

2000-11-14"plugin_api.c" needs to include <glib.h>, to define G_HAVE_GINT64 onGuy Harris4-9/+12
platforms that have "gint64". Fix plugin-table lines for "dissector_delete()", "dissect_data()", "prefs_register_module()", and "prefs_register_uint_preference()". The MGCP dissector uses routines from GLib, so when building it as a DLL for Windows, it has to be linked with "glib-XXX.lib". svn path=/trunk/; revision=2643
2000-11-14Add tvb_set_child_real_data_tvbuff(), which allows you to tell theGilbert Ramirez2-9/+32
tvbuff routines that a particular TVBUFF_REAL_DATA tvbuff is a "child" of another tvbuff. This link is utilized during a tvb_free_chain(), so that the child is freed when no longer necessary. svn path=/trunk/; revision=2642

2000-11-13Move "bytes_to_str()" to "strutil.c" from "packet.c" - it's just aGuy Harris18-253/+285
string formatter, like "format_text()", and, as "tvbuff.c" now calls it (*vide infra*), we don't want to have to make "tvbuff.c" drag "packet.h" in just to declare "bytes_to_str()". It's now declared in "strutil.h", so include it in modules that use "bytes_to_str()" and weren't already including it. Add a "tvb_bytes_to_str()" wrapper that calls "tvb_get_ptr()" to get a pointer to a chunk of N bytes at a given offset in a tvbuff and then hands that chunk to "bytes_to_str()". Convert the code that was doing that to use "tvb_bytes_to_str()" instead (which caught what I suspect is a bug in the Q.2931 dissector, where it was handing an offset of 0 to "tvb_get_ptr()" - a cut-and-pasteo, I think). Tvbuffify the ARP dissector. svn path=/trunk/; revision=2634
2000-11-13If either of the "tvb_new_subset()" calls throws an exception, it meansGuy Harris1-1/+19

2000-11-13"It's pronounced 'volatile pointer to tvbuff_t' but it's spelledGuy Harris2-18/+9
'tvbuff_t *volatile'." Makes "Throat-Warbler Mangrove" vs. "Luxury-Yacht" sound almost normal.... Type-qualified pointers to non-type-qualified objects are a barrel of fun in C. The way you declare a volatile pointer named "bar" to a *non-volatile* "foo" is foo *volatile bar; as opposed to a non-volatile pointer "bar" to a volatile "foo", which is volatile foo *bar; GCC's complaint about variables being clobbered by longjmp refers to the fact that "longjmp()" isn't guaranteed to restore variables stored in registers to the values they had at the time of the "longjmp()" (if "setjmp()" stuffs the current register values in the "jmp_buf", and "longjmp()" just reloads them rather than walking the stack to restore all register values pushed onto the stack, the values at the time of the "setjmp()" will be restored, clobbering any updates done after the "setjmp()"); the workaround provided in ANSI C is to declare the variables in question "volatile", which will keep them out of registers (or any other place that "setjmp()"/"longjmp()" can't handle). svn path=/trunk/; revision=2631

2000-11-13Don't overwrite the "Info" column in the SDP dissector, either - appendGuy Harris1-2/+16
to it, so as not to stomp on what the protocol that's using SDP put there. svn path=/trunk/; revision=2625
2000-11-12As RFC 2327 says, "SDP is purely a format for session description - itGuy Harris2-5/+3
does not incorporate a transport protocol, and is intended to use different transport protocols as appropriate including the Session Announcement Protocol [4], Session Initiation Protocol [11], Real- Time Streaming Protocol [12], electronic mail using the MIME extensions, and the Hypertext Transport Protocol." As such, it shouldn't set the protocol column to SDP, as that means the protocol column won't indicate what the transport protocol was; instead, it should append "/SDP" to the protocol column - RTSP was, after calling "dissect_sdp()", setting the protocol column to "RTSP/SDP", and this change means that all protocols using SDP will have the protocol column set in that fashion, and that the RTSP dissector doesn't have to explicitly set the protocol column to cause that to happen. svn path=/trunk/; revision=2624
2000-11-12Add a Makefile.nmake for the MGCP plugin, and updateGuy Harris1-1/+6
"plugins/Makefile.nmake" to build that plugin. Add to the table of routines callable from plugins "old_dissector_add()", "old_dissect_data()", and "proto_is_protocol_enabled()", so that the Gryphon dissector can build on Windows. Move the includes of "plugins/plugin_api.h" and "moduleinfo.h" before all the other includes, except for "config.h", in "plugin-mgcp.c", to match what the Gryphon dissector does; "plugins_api.h" must be included before any of the routines whose names it #defines in order for the plugin to build on Windows. (It still doesn't build on Windows, as still more routines need to be added to the table of routines callable from plugins, but tomorrow is another day. Making libethereal a DLL may obviate the need for that table, *if* all the routines called from a plugin are in libethereal, as I think routines in a DLL, even a run-time-loaded DLL, can call routines from another DLL as long as those routines are exported from the other DLL.) svn path=/trunk/; revision=2623

2000-11-12"pinfo->current_proto" is typically set to an acronym or short name forGuy Harris1-2/+2
the protocol, not the filter name for the protocol, so it should be "AIM", not "aim". svn path=/trunk/; revision=2621
2000-11-12"wtap_loop()" no longer has problems with packet offsets of 0, so weGuy Harris2-22/+73
don't need to work around that. The offset, for a given packet, at which "ascend_seek()" should start searching for that packet's header must be computed separately from the offset, for that packet, at which "ascend_seek()" should start searching for the *next* packet - if the file is a "wdd" capture, and the packet has a "Date:" header and a WD_DIALOUT_DISP header, the search for that packet should start at the beginning of the "Date:" header, but the search for the next packet should start after the WD_DIALOUT_DISP header, as if we start it after the "Date:" header, the search will stop at the packet's own WD_DIALOUT_DISP header, as a packet could have a WD_DIALOUT_DISP header but no "Date:" header. svn path=/trunk/; revision=2620

svn path=/trunk/; revision=2618
2000-11-12Not all packets in a "wdd" dump necessarily have a "Cause an attempt toGuy Harris3-21/+42
place call to" header (I presume this can happen if there was a call in progress when the packet was sent or received); don't require the Date: 01/12/1990. Time: 12:22:33 Cause an attempt to place call to 14082750382 to be present in every packet. (Only the date on the first packet is used, and only if it's present in the first packet; if the first packet doesn't have a date, we can't easily go back and fix up the previous packets, *especially* in programs such as Tethereal and editcap which make only one pass through the capture. We set the called number to a null string if that's the case; we could assume, in the sequential pass, that it's the phone number from the last call, and remember that for use when doing random access.) svn path=/trunk/; revision=2617

2000-11-12Don't set the "Protocol" column to "GIOP" until we've decided that theGuy Harris1-9/+11
packet is a GIOP packet. If it has a GIOP header but doesn't have a version number we handle, accept it as a GIOP packet; if we don't do that, we should simply return FALSE *without* changing any of the columns or putting anything into the protocol tree. svn path=/trunk/; revision=2615
2000-11-12Tvbuffify the SMTP dissector.Guy Harris1-81/+159
Don't assume that we start out getting commands from the client - the capture may have started in the middle of a transaction, and we may be getting a message body from the client instead. Only treat stuff as commands if it consists of four alphabetic characters followed either by an end-of-line or a space. Commands in SMTP are case-insensitive; when looking for "DATA", do a case-insensitive comparison. If the packet contains the message body, just put "Message Body" in the summary, don't put any of the message body itself in there. If it's a command, put "Command:" in the summary before the first line of the command. When putting the message body into the protocol tree, give each line its own entry, rather than putting the entire body in as one entry. Don't put an entry into the protocol tree for a command parameter if there is no command parameter. svn path=/trunk/; revision=2614

by itself as a line ending, as well as treating CR LF and LF as line endings. Tweak the Telnet dissector to treat LF and CR NUL as line endings, but not to treat CR by itself as a line ending (that's not exactly what the NVT specification in the Telnet RFC specifies, but the resulting output may be a bit more readable that way). svn path=/trunk/; revision=2613

2000-11-11Get rid of the definitions of LITTLE_ENDIAN and BIG_ENDIAN inGuy Harris4-63/+21
"epan/pint.h" - they caused GCC to whine about them being redefined when I compiled on FreeBSD 3.4. Get rid of the stuff in "packet-ipv6.h" that defines various bit vectors differently depending on the byte order of the machine; instead, define them so that they work with items in host byte order. This lets us use a number of them rather than using hardwired hex values. Put "frag.ip6f_offlg" in host byte order before using it; this means that IP6F_MORE_FRAG can still be used even though it now works only on items in host byte order. svn path=/trunk/; revision=2610
2000-11-11Don't have separate versions of "ddp_hops()" and "ddp_len()" onGuy Harris1-11/+11
big-endian and little-endian platforms; just put "ddp.hops_len" in host byte order and have one version. (This removes one usage of BIG_ENDIAN and LITTLE_ENDIAN from Ethereal - our redefining of them causes warnings on FreeBSD 3.4, so I'd like not to export them to all the dissectors if possible - and also fixes "ddp_hops()" to work correctly on little-endian machines, as the little-endian version wasn't byte-swapping its argument.) svn path=/trunk/; revision=2609
2000-11-11Simplify the state machine:Guy Harris1-42/+63
you're either reading commands, or you're reading message data; if you're reading commands, and you see a DATA command, you start reading data; if you're reading data, and you see an EOM, you start reading commands. Also, *always* fill in the per-frame data you allocate for a frame, and *always* attach it to the packet. The old state machine assumed it was done with the SMTP conversation once it saw an EOM, and the dissector wouldn't fill in the per-frame data it'd allocated and attach it to the packet if it thought it was done with the SMTP conversation. This meant that: 1) the per-frame data allocated for frames following the EOM (e.g., a QUIT command) would contain random junk for data such as the packet type; 2) that per-frame data would be re-allocated every time the frame was looked at, as it wouldn't be attached to the frame, so you might well get *different* random junk each time the frame was looked at. This caused Tethereal and Ethereal to sometimes fail to recognize commands following the EOM - but it wouldn't *always* fail to do so, sometimes it'd work and sometimes it wouldn't. Fix a comment; conversations are *not* removed during filter operations, and the visited flag is *not* cleared during a filter operation - that's only true on a *redissection* operation. In any case, given that frames can, after the initial sequential scan through the capture, be visited in any order, and visited repeatedly, it's irrelevant whether conversations are removed or not - we have to associate with each frame information telling us how to process it. svn path=/trunk/; revision=2608

2000-11-11We have to set "x25.flags" in the Wiretap pseudo-header if the captureGuy Harris2-26/+123
is WTAP_ENCAP_LAPB *or* WTAP_ENCAP_V120, and we have to set "p2p.sent" in the capture file for *all* WTAP_ENCAP_LAPD captures; fix the i4btrace and Sniffer capture file readers to do so. (XXX - should we eliminate "x25.flags", and use "p2p.sent" instead? The directions for X.25 are DTE->DCE and DCE->DTE, not "sent" and "received", but I suspect that "sent" and "received" should be thought of from the point of view of the DTE, so DTE->DCE is "sent" and DCE->DTE is "received"; the directions for ISDN are user->network and network->user, but I suspect that "sent" and "received" should be thought of from the standpoint of the user equipment, so user->network is "sent" and network->user is "received".) svn path=/trunk/; revision=2606
2000-11-11In "wdd" captures:Guy Harris3-17/+41
fix the interpretation of the date and time reported in capture files; use that date and time only to set the start date and time of the capture, not to generate the time stamp for every packet. Make the "struct tm" used for that local to the code to handle that production in the grammar, rather than global. For all captures, we *can* now fstat a compressed file (and have been able to do so for a while, in fact), so revert to doing so and using the ctime of the capture file if we can't get a date and time from the file's contents. svn path=/trunk/; revision=2605
2000-11-11Add some comments, and fix one comment.Guy Harris1-4/+9
Remove what appear to be a pair of dangling "else"s. Before calling "mktime()" on a "struct tm", you have to set "tm_isdst", so it knows what to do about daylight savings time; set it to -1, so it picks the appropriate time (except, presumably, for those times that don't exist, when the clock is moved forward, where there is no appropriate time, and those times that exist twice, when the clock is moved backward, where there are *two* times and you can't tell which is appropriate). svn path=/trunk/; revision=2604
