2000-02-15Create a header file for every packet-*.c file. Prune the packet.h file.Gilbert Ramirez1-1/+5
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
2000-01-29Fix a bug in the extraction of the sequence number.Gilbert Ramirez1-5/+4
svn path=/trunk/; revision=1575
2000-01-24Fix a bunch of dissectors to use "pi.captured_len" rather thanGuy Harris1-2/+2
"fd->cap_len" for the frame length - or to use macros such as "BYTES_ARE_IN_FRAME()", "IS_DATA_IN_FRAME()", and "END_OF_FRAME", which use "pi.captured_len" - so that they correctly handle frames where the actual data length of the packet is less than the size of the raw frame, e.g. with encapsulations such as ISL. svn path=/trunk/; revision=1531
2000-01-23In "dissect_eth()", update "pi.len" and "pi.captured_len" regardless ofGuy Harris1-5/+5
whether we're building a protocol tree or not. Make "dissect_eth()" use "BYTES_ARE_IN_FRAME()" to see if we have a full Ethernet header - it can be called with a non-zero offset, if Ethernet frames are encapsulated inside other frames (e.g., ATM LANE). Make capture routines take an "offset" argument if the corresponding dissect routine takes one (for symmetry, and for Cisco ISL or any other protocol that encapsulates Ethernet or Token-Ring frames inside other frames). Pass the frame lengths to capture routines via the "pi" structure, rather than as an in-line argument, so that they can macros such as "BYTES_ARE_IN_FRAME()" the way the corresponding dissect routines do. Make capture routines update "pi.len" and "pi.captured_len" the same way the corresponding diseect routines do, if the capture routines then call other capture routines. Make "capture_vlan()" count as "other" frames that are too short, the way other capture routines do. svn path=/trunk/; revision=1525
2000-01-20Joerg Mayer's updates to the VINES dissector and to protocol layersGuy Harris1-1/+4
above VINES. svn path=/trunk/; revision=1514
1999-11-30Add IPX to packet stats during capture.Gilbert Ramirez1-1/+4
svn path=/trunk/; revision=1173
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-47/+94
dynamically-assigned "ett_" integer values, assigned by "proto_register_subtree_array()"; this: obviates the need to update "packet.h" whenever you add a new subtree type - you only have to add a call to "proto_register_subtree_array()" to a "register" routine and an array of pointers to "ett_", if they're not already there, and add a pointer to the new "ett_" variable to the array, if they are there; would allow run-time-loaded dissectors to allocate subtree types when they're loaded. svn path=/trunk/; revision=1043
1999-10-12New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1-4/+7
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
1999-09-11Added filter items for PPP Multilink's fragemnt flags and session number.Gerald Combs1-7/+26
svn path=/trunk/; revision=665
1999-09-11Added support for PPP Multilink Protocol (MP). Modified dissect_ppp_stuffGerald Combs1-5/+98
to recognize and handle protocol field compression. svn path=/trunk/; revision=651
1999-08-28PPP options in LCP, IPCP, etc. are like IP and TCP options - one octetGuy Harris1-162/+581
of option code, one octet of length (which includes the two option code and length bytes), followed by 0 or more octets of option data, with some options being fixed-length and some being variable-length. Put some stuff from the PPP control protocol option parsing code into the IP-and-TCP option parsing code, and use the latter instead of the former. (That code might also be usable for CDP as well, with some stuff added to it.) Shuffle the arguments to "dissect_ip_tcp_options()" to resemble those of various other dissectors (i.e., with the "proto_tree *" at the end). Add in code to dissect a pile of PPP options documented in various RFCs. svn path=/trunk/; revision=601
1999-08-25Add in the Async Map option.Guy Harris1-61/+151
Add in the Identification and Time Remaining codes for LCP. Add in a pile of other LCP options, albeit without anything more than names for now. Don't say "1 bytes", say "1 byte". Don't use "dissect_data()" to dissect part of a *CP packet, and don't dissect opaque data if there're zero bytes of it. svn path=/trunk/; revision=578
1999-08-25Put in support for dissecting LCP and IPCP options.Guy Harris1-115/+281
Have a common routine to parse both LCP and IPCP, as IPCP is based on LCP. Have only one "value_string" array of PPP protocol types, with all the types we know about. svn path=/trunk/; revision=577
1999-08-25The bulk of the PPP dissection is common between "dissect_ppp()" andGuy Harris1-63/+50
"dissect_payload_ppp()"; put it into a common routine, called by both (which means we now dissect LCP and IPCP in PPP requests even if they aren't inside PPPOE or GRE packets). svn path=/trunk/; revision=576
1999-08-24In the summary display for PPP frames, make the protocol PPP (which willGuy Harris1-9/+9
get overridden in any case). svn path=/trunk/; revision=560
1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-3/+17
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
1999-07-07Created a new protocol tree implementation and a new display filterGilbert Ramirez1-23/+19
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
1999-06-11Added PPPoE, PPTP, GRE, and ISAKMP dissectors.Gilbert Ramirez1-9/+245
svn path=/trunk/; revision=303
1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1-14/+21
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
1999-02-09When doing a capture, decode enough of the incoming packets to correctlyGuy Harris1-1/+13
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
1998-11-17* Added column formatting functionality.Gerald Combs1-8/+11
* 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
1998-11-05Add in a bunch of #defines for packet types.Guy Harris1-5/+48
Show the packet type as a string, as well as a hex number, in the detail display. Show the packet type as a hex number in the summary display if it's not a packet type we know about. Don't put the "N on link, M captured" stuff in the PPP detail display, as that's now in the frame detail display. Handle IPv6, Appletalk, IPX, and Vines. svn path=/trunk/; revision=79
1998-10-10* OSPF alignment fixes (Gerald)Gerald Combs1-1/+5
* FDDI support (Laurent, Guy) svn path=/trunk/; revision=36
1998-09-27Merged in a _huge_ patch from Guy Harris. It adds a time stap column,Gerald Combs1-7/+7
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
1998-09-25* Ethernet manufacturer support (Laurent)Gerald Combs1-15/+11
* PPP fixes (Gerald) * Null/loopback interface support (Gerald) svn path=/trunk/; revision=25
