* Rename "asn1_octet_string_value_decode()" toGuy Harris2000-12-247-430/+706
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "asn1_string_value_decode()", as it can be used for various character string types as well. Turn "asn1_octet_string_decode()" into "asn1_string_decode()", which takes an additional argument giving the tag expected for the string in question, and make "asn1_octet_string_decode()" a wrapper around it. Clean up the ASN.1 dissection in the Kerberos dissector, making more use of the code in "asn1.c", wrapping more operations up in macros, and doing some more type checking. Use "REP" rather than "RESP" in names and strings; "REP" is what the Kerberos spec uses. Make the routines in the Kerberos dissector not used outside that dissector static. Fix some problems with the dissection of strings in the Kerberos dissector (it was extracting the data from the wrong place in the packet). In Kerberos V5, the "kvno" item in the EncryptedData type is optional; treat it as such. Treat integers as unsigned in the Kerberos dissector. svn path=/trunk/; revision=2777

* Add support for the DLT_LINUX_SLL capture type in the current CVSGuy Harris2000-12-237-9/+341
| | | | | | | | | | | | | | version of libpcap; that's used on Linux for captures on the "any" device (which captures from all interfaces simultaneously) and for captures on devices whose link-layer type libpcap doesn't (yet) support natively. The spanning tree code, when checking for GV{M,R,...}P packets, must first check whether the link-layer destination address is, in fact, an Ethernet-style address; on Linux cooked captures, there *is* no destination address, so it's of type AT_NONE, not AT_ETHER. svn path=/trunk/; revision=2772

* Add code to check the checksums of TCP segments and UDP datagrams;Guy Harris2000-12-138-59/+373
| | | | | | | | | | | | | | | | | | | replace the existing checksummer with a modified version of the BSD checksumming code. Add a flag to the "packet_info" structure to indicate that a packet is the first fragment of a fragmented datagram, so that the checksummers won't try to checksum those. (It doesn't seem to add a lot of CPU overhead, so we don't introduce a flag to disable it, yet. Further checks may be necessary to see whether the overhead is just swamped by other overheads when scanning through a capture dissecting all frames, or if it truly is negligible.) Make the Boolean preference option controlling whether to make the top-level protocol tree item for TCP display a packet summary static to the TCP dissector (it doesn't need to be accessible outside the TCP dissector). svn path=/trunk/; revision=2751

* Add a "col_clear()" routine, to clear a column; it appears (and itGuy Harris2000-12-046-84/+109
| | | | | | | | | | | | | | | | | | | | | | doesn't just seem to be a profiling artifact) that, at least on FreeBSD 3.4, it's significantly more efficient to clear out a column by stuffing a '\0' into the first byte of the column data than to do so by copying a null string (I guess when copying one byte, the fixed overhead of the procedure call and of "strcpy()" is significant). Have the TCP dissector set the Protocol column, and clear the Info column, before doing anything that might cause an exception to be thrown, so that if we *do* get an exception thrown, the frame at least shows up as TCP. Instead of, in the TCP dissector, constructing a string and then stuffing it into the Info column, just append to the Info column, which avoids one string copy. Pass a "frame_data" pointer to dissectors for TCP and IP (and PPP) options, so they can use it to append to the Info column. svn path=/trunk/; revision=2744

Get rid of the "tvb_compat()" call in the IPX dissector - it calls all dissectors through handles or lookup tables, and thus any backwards-compatibility stuff is done by the code in libethereal. svn path=/trunk/; revision=2735
