1999-09-22Another change to make packet-tr more intelligent with regard toGilbert Ramirez1-21/+34
short packets. Also increased RIF processing from 18 to 30 bytes of RIF, as I learned that the token-ring spec changed. Don't call next dissector if there are no more bytes in packet. svn path=/trunk/; revision=698
1999-09-17Changed short packet handling in TR code to understand minimum-lengthGilbert Ramirez1-2/+3
TR packets (it's a variable-length header, remember). Added lots of proto_tree-style fields to TRMAC code. svn path=/trunk/; revision=683
1999-09-15Handle short packets in the capture and dissect stages more intelligently.Gilbert Ramirez1-2/+14
svn path=/trunk/; revision=680
1999-09-15Changed (again) the way that the FT_BOOLEAN field type works internally.Gilbert Ramirez1-4/+4
Dissector code can add FT_BOOLEAN fields to the proto_tree and pass TRUE or FALSE values (non-zero and zero values). The display filter language, however, treats the checking for the existence of a FT_BOOLEAN field as the checking for its truth. Before this change, packet-tr.c was the only dissector using FT_BOOLEAN fields, and it only added the field to the proto_tree if the TRUE; the dissector was determining the difference between the check for existence and the check for truth. I made this change because packet-ppp.c added some FT_BOOLEAN fields and added them to the tree regardless of truth value, It's more natural just to do it this way and let the display filter code worry about whether to check for existence or truth. So that's how it works now. svn path=/trunk/; revision=679
1999-09-09Removed two cases where protocol decoding assumed that the data in theGilbert Ramirez1-2/+5
packets were correct. Bad packets could cause segfaults. svn path=/trunk/; revision=641
1999-08-27Changed packet-tr.c to insert tr.sr, a FT_BOOLEAN field, only if tr.srGilbert Ramirez1-2/+4
is true. The test for truth now becomes a test for existence. The dfilter grammar no longer recognizes 'true' and 'false', since you can now check a boolean field via: tr.sr or by its negation: !tr.sr svn path=/trunk/; revision=591
1999-08-27The token-ring decoder now takes into account some really garbledGilbert Ramirez1-25/+112
TR packets that are seen on Linux 2.0 boxes (viewing your own packets before they get to the wire). Thanks to Tom Gallagher <Tom.Gallagher@madge.com> for providing the patch. svn path=/trunk/; revision=589

1999-08-20Add support for reading Full Frontal ATM from an ATM Sniffer captureGuy Harris1-52/+59
file, instead of throwing out all but LANE or RFC 1483 data frames and pretending that the former are just Ethernet or Token-Ring frames. Add some level of decoding for ATM LANE, but not all of it; the rest, including decoding non-LANE frames, is left as an exercise for somebody who has captures they want to decode, an interest in decoding them, ATM expertise, and time.... svn path=/trunk/; revision=523
1999-08-10Fixed a bug in displaying RIF ring/bridge pairs.Gilbert Ramirez1-7/+4
svn path=/trunk/; revision=456
1999-08-01Changed the display filter scanner from GLIB's GScanner to lex. The codeGilbert Ramirez1-12/+1
as it standed depends on your lex being flex, but that only matters if you're a developer. The distribution will include the dfilter-scanner.c file, so that if the user doesn't modify dfilter-scanner.l, he won't need flex to re-create the *.c file. The new lex scanner gives me better syntax checking for ether addresses. I thought I could get by using GScanner, but it simply wasn't powerful enough. All operands have English-like abbreviations and C-like syntax: and, && ; or, || ; eq, == ; ne, != ; , etc. I removed the ETHER_VENDOR type in favor of letting the user use the [x:y] notation: ether.src[0:3] == 0:6:29 instead of ether.srcvendor == 00:06:29 I implemented the IPXNET field type; it had been there before, but was not implemented. I chose to make it use integer values rather than byte ranges, since an IPX Network is 4 bytes. So a display filter looks like this: ipx.srcnet == 0xc0a82c00 rather than this: ipx.srcnet == c0:a8:2c:00 I can supposrt the byte-range type IPXNET in the future, very trivially. I still have more work to do on the parser though. It needs to check ranges when extracting byte ranges ([x:y]) from packets. And I need to get rid of those reduce/reduce errors from yacc! svn path=/trunk/; revision=414
1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-22/+22
allowing users to filter on the existence of these protocols. I also added packet-clip.c to the Nmake makefile. svn path=/trunk/; revision=402
1999-07-15Modified the proto_register_field_array usage again. Thanks to Guy'sGilbert Ramirez1-22/+61
suggestion, this new method using a static array should use less memory and be faster. It also has a nice side-effect of making the source-code more readble, IMHO. Changed the print routines to look for protocol proto_data instead of looking at the text label as they did before, hoping that the data hex dump field item starts with "Data (". Added the -G keyword to ethereal to make it dump a glossary of display filter keywords to stdout and exit. This data is then formatted with the doc/dfilter2pod perl program to pod format, which is combined with doc/ethereal.pod.template to create doc/ethereal.pod, from which the ethereal manpage is created. This way we can keep the manpage up-to-date with a list of fields that can be filtered on. svn path=/trunk/; revision=364
1999-07-07Created a new protocol tree implementation and a new display filterGilbert Ramirez1-107/+143
mechanism that is built into ethereal. Wiretap is now used to read all file formats. Libpcap is used only for capturing. svn path=/trunk/; revision=342
1999-06-16Found a small bug in how the Token-Ring code tried to be smart and lookedGilbert Ramirez1-3/+3
for RIF bytes w/o the source-route bit being set. svn path=/trunk/; revision=316
1999-06-14Changed the Access Control and Frame Control fields in the Token-Ring headerGilbert Ramirez1-15/+44
to use the decode_*_bitfield() routines. This needed to happen anyway, but I finally made the change so that I can figure out how I'm going to handle bitfield fields in my experiment of changing the implementation of the protocol tree in ethereal. svn path=/trunk/; revision=311
1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1-38/+26
reference the protocol tree with struct proto_tree and struct proto_item objects. That way, the packet decoding source code file can be used with non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged some of the information in packet.h to more appropriate places (like other packet-*.[ch] files). svn path=/trunk/; revision=223
1999-03-01Small fixes for alignment, and #include for gtk+-1.1.x/glib-1.1.xGilbert Ramirez1-3/+3

1999-02-09When doing a capture, decode enough of the incoming packets to correctlyGuy Harris1-1/+95
update the packet counts and percentages in the dialog box popped up during a capture, even for non-Ethernet captures. svn path=/trunk/; revision=184
1999-01-08A bad frame control value could crash ethereal because I didn't doGilbert Ramirez1-5/+15
proper bounds checking. Fixed. svn path=/trunk/; revision=164
1998-11-17* Added column formatting functionality.Gerald Combs1-7/+9
* Added check_col(), add_col_str() and add_col_fmt() to replace references to ft->win_info. * Added column prefs handling code. svn path=/trunk/; revision=97
1998-11-12A lengthy patch to add the wiretap library. Wiretap is not used by defaultGilbert Ramirez1-2/+1
because it is still in its infancy, but it can be compiled in optionally. The library exists in its own subdirectory ethereal/wiretap. This patch also edits all the packet-*.c files to remove the #include <pcap.h> line which is unnecessary in these files. In the ethereal code, file.c is the most heavily modified with #ifdef WITH_WIRETAP lines for the optional library. svn path=/trunk/; revision=82

svn path=/trunk/; revision=41
1998-09-27Merged in a _huge_ patch from Guy Harris. It adds a time stap column,Gerald Combs1-8/+8
generalizes the column printing code, adds a "frame" tree item to the tree view, and fixes a bunch of miscellaneous coding bugs. svn path=/trunk/; revision=31
1998-09-17I cleaned up the TR code by using variables that correspond to the TR headerGilbert Ramirez1-42/+92
fields. I got rid of a lot of pd[x] type stuff. I also made the TR code a bit smarter again. With Linux 2.0.x and oltr, the source-route bit is cleared before we get it. I can now detect more packets that were source- routed but had their SR bit cleared. svn path=/trunk/; revision=16
