* Add tvbuff class.Gilbert Ramirez2000-05-111-153/+153
| | | | | | | | | | | | | | | Add exceptions routines. Convert proto_tree_add_*() routines to require tvbuff_t* argument. Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as the tvbuff_t* argument to proto_tree_add_*() routines. dissect_packet() creates a tvbuff_t, wraps the next dissect call in a TRY block, will print "Short Frame" on the proto_tree if a BoundsError exception is caught. The FDDI dissector is converted to use tvbuff's. svn path=/trunk/; revision=1939

* Change the sub-dissector handoff registration routines so that theGilbert Ramirez2000-04-131-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sub-dissector table is not stored in the header_field_info struct, but in a separate namespace. Dissector tables are now registered by name and not by field ID. For example: udp_dissector_table = register_dissector_table("udp.port"); Because of this different namespace, dissector tables can have names that are not field names. This is useful for ethertype, since multiple fields are "ethertypes". packet-ethertype.c replaces ethertype.c (the name was changed so that it would be named in the same fashion as all the filenames passed to make-reg-dotc) Although it registers no protocol or field, it registers one dissector table: ethertype_dissector_table = register_dissector_table("ethertype"); All protocols that can be called because of an ethertype field now register that fact with dissector_add() calls. In this way, one dissector_table services all ethertype fields (hf_eth_type, hf_llc_type, hf_null_etype, hf_vlan_etype) Furthermore, the code allows for names of protocols to exist in the etype_vals, yet a dissector for that protocol doesn't exist. The name of the dissector is printed in COL_INFO. You're welcome, Richard. :-) svn path=/trunk/; revision=1848
* Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez2000-03-121-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Make "reinit_x25_hashtable()" static (it's not explicitly called fromGuy Harris2000-02-221-3/+3
| | | | | | | | | | | outside "packet-x25.c", it's only registered as a protocol init routine), and explicitly declare it as taking no arguments (GCC doesn't complain about passing a pointer to a routine with an unspecified argument list to "register_init_routine()", which expects a pointer to a routine with no arguments, but Microsoft Visual C{++} 6.0 does complain about it). svn path=/trunk/; revision=1664

* Renamed init_dissect_x25() to reinit_x25_hashtable() and actually used it !Olivier Abad2000-02-181-2/+2
| | | | | | | | | | | | This function is used to re-initialize the hash table used by the X.25 dissector to record the upper layer protocol used by each VC. The hash table should be re-initialized each time we read / start a new capture. I moved the definition of the function from packet.h to packet-x25.h, and added calls to reinit_x25_hashtable() in read_cap_file (file.c) and do_capture (capture.c). svn path=/trunk/; revision=1644
* Create a header file for every packet-*.c file. Prune the packet.h file.Gilbert Ramirez2000-02-151-1/+3
| | | | | | | | | | | | | This change allows you to add a new packet-*.c file and not cause a recompilation of everything that #include's packet.h Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list. Add #define YY_NO_UNPUT 1 to the lex source so that the yyunput symbol is not defined, squelching a compiler complaint when compiling the generated C file. svn path=/trunk/; revision=1637

| | | | | | | | | | | | more display filters for X.25; no LCN in X.25 RESTART / DIAGNOSTIC / REGISTRATION packets; support for nettl file format (nettl is a trace tool for HP-UX). For now, it only supports traces for X.25 interfaces (tested with HP-UX 10.20). svn path=/trunk/; revision=879
* New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1999-10-121-3/+6
| | | | | | | | | | | | | | | | | | | | | the base for numbers to be displayed in, bitmasks for bitfields, and blurbs (which are one or two sentences describing the field). proto_tree_add*() routines now automatically handle bitfields. You tell it which header field you are adding, and just pass it the value of the entire field, and the proto_tree routines will do the masking and shifting for you. This means that bitfields are more naturally filtered via dfilter now. Added Phil Techau's support for signed integers in dfilters/proto_tree. Added the beginning of the SNA dissector. It's not complete, but I'm committing it now because it has example after example of how to use bitfields with the new header_field_info struct and proto_tree routines. It was the impetus to change how header_field_info works. svn path=/trunk/; revision=815

Move the routine, used for the "Tools/Summary" display, that turns a wiretap file type into a descriptive string for it into the wiretap library itself, expand on some of its descriptions, and add an entry for files from a RADCOM analyzer. Have "Tools/Summary" display the snapshot length for the capture. svn path=/trunk/; revision=417
