2003-07-24From Markus Seehofer: check the correct byte (the second byte, not theguy1-3/+3
first byte) in a host membership query to distinguish between IGMPv1 and IGMPv2. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8081 f5534014-38df-0310-8fa8-9805f1628bb7
2003-07-23Fix a bug reported by Dave Nicoson:jmayer1-9/+4
Igmp v1 membership reports should not be misdetected as v2 reports (don't confuse the query with the report). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8074 f5534014-38df-0310-8fa8-9805f1628bb7
2003-03-04When deciding whether we have enough data in a lower-level packet toguy1-3/+3
attempt reassembly of a higher-level packet that includes the lower-level packet, use "tvb_bytes_exist()" to check whether all the data that's to be included in the reassembly is available, rather than by checking whether the packet is short. Add some checks of that sort that were missing. Use the reported length of the packet when doing reassembly. Make the "iphdrlen" field of a "packet_info" structure be the length of the IP header in bytes, not in 4-byte words. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@7274 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-28Removed trailing whitespaces from .h and .c files using thejmayer1-18/+18
winapi_cleanup tool written by Patrik Stridvall for the wine project. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6117 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hjmayer1-10/+6
equivalents for the toplevel directory. The removal of winsock2.h will hopefully not cause any problems under MSVC++, as those files using struct timeval still include wtap.h, which still includes winsock2.h. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5932 f5534014-38df-0310-8fa8-9805f1628bb7
2002-05-02From Joerg Mayer: get rid of unused arguments.guy1-7/+7
git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5348 f5534014-38df-0310-8fa8-9805f1628bb7
2002-02-01Export "igmp_checksum()" from the IGMP dissector and give it additionalguy1-15/+15
arguments that specify the header field indices for the checksum field and the "checksum is bad" Boolean, and have the dissectors for some protocols that use IGMP (DVMRP, MRDISC, MSNIP) use it rather than having their own checksumming routines. Also, fix it to correctly add the "checksum is bad" Boolean. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4665 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-21Include files from the "epan" directory and subdirectories thereof withguy1-2/+2
"epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4586 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-20Allow a length of -1 to be specified when adding FT_NONE and FT_PROTOCOLguy1-3/+3
items to the protocol tree; it's interpreted as "the rest of the data in the tvbuff". This can be used if 1) the item covers the entire packet or the remaining payload in the packet or 2) the item's length won't be known until it's dissected, and will be then set with "proto_item_set_len()" - if an exception is thrown in the dissection, it means the item ran *past* the end of the tvbuff, so saying it runs to the end of the tvbuff is reasonable. Convert a number of "proto_tree_add_XXX()" calls using "tvb_length_remaining()", values derived from the result of "tvb_length()", or 0 (in the case of items whose length is unknown) to use -1 instead (using 0 means that if an exception is thrown, selecting the item highlights nothing; using -1 means it highlights all the data for that item that's available). In some places where "tvb_length()" or "tvb_length_remaining()" was used to determine how large a packet is, use "tvb_reported_length()" or "tvb_reported_length_remaining()", instead - the first two calls indicate how much captured data was in the packet, the latter two calls indicate how large the packet actually was (and the fact that using the latter could cause BoundsError exceptions to be thrown is a feature - if such an exception is thrown, the frame really *was* short, and it should be tagged as such). Replace some "proto_tree_add_XXX()" calls with equivalent "proto_tree_add_item()" calls. Fix some indentation. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4578 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-23From Ronnie Sahlberg: initial NDMPv3 support, and an update to hisguy1-2/+2
e-mail address. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4444 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"guy1-12/+12
structure to the "packet_info" structure; only stuff that's permanently stored with each frame should be in the "frame_data" structure, and the "column_info" structure is not guaranteed to hold the column values for that frame at all times - it was only in the "frame_data" structure so that it could be passed to dissectors, and, as all dissectors are now passed a pointer to a "packet_info" structure, it could just as well be put in the "packet_info" structure. That saves memory, by shrinking the "frame_data" structure (there's one of those per frame), and also lets us clean up the code a bit. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4370 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"guy1-2/+5
take a dissector handle as an argument, rather than a pointer to a dissector function and a protocol ID. Associate dissector handles with dissector table entries. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4308 f5534014-38df-0310-8fa8-9805f1628bb7
2001-07-12Include "snprintf.h" if necessary, as we use "snprintf()".guy1-1/+5
git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3694 f5534014-38df-0310-8fa8-9805f1628bb7
2001-07-11Add entries for traceroute requests and responses to the value_stringguy1-24/+44
table for IGMP packet types (we treat requests as "Query or Request", as the type doesn't say which it is). Base the query vs. request decision on the reported length of the packet, not the captured length. Checksum the packet only if it's not fragmented and the captured length is greater than or equal to the amount to be checksummed, and, for requests where we don't wire in the length to be checksummed, base it on the reported length of the packet, not the captured length. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3683 f5534014-38df-0310-8fa8-9805f1628bb7
2001-07-11Just add the "hf_type" field in a traceroute message withguy1-6/+5
"proto_tree_add_uint_format()", rather than adding it as a hidden field and then adding a text entry. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3682 f5534014-38df-0310-8fa8-9805f1628bb7
2001-07-10IGMP fixes and multicast traceroute support, from Heikki Vatiainen.guy1-37/+300
Assorted other fixes. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3677 f5534014-38df-0310-8fa8-9805f1628bb7
2001-07-02Add PIMv1 support.guy1-47/+7

2001-06-18From Joerg Mayer: explicitly fill in all members of aguy1-23/+23
"header_field_info" structure, including the ones that are later set by the routines to register fields. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3561 f5534014-38df-0310-8fa8-9805f1628bb7
2001-06-12DVMRP support, from Ronnie Sahlberg.guy1-19/+31
Give "packet-igmp.c" an RCS ID. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3539 f5534014-38df-0310-8fa8-9805f1628bb7
2001-05-25Update Gerald's e-mail address.guy1-4/+30
Use "col_add_fstr()" to set the Info column, rather than "sprintf()"ing to a buffer and using "col_add_str()". Add a routine that dissects unknown types of IGMP messages, and use it for all IGMP messages for which we don't have a dissector. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3452 f5534014-38df-0310-8fa8-9805f1628bb7
2001-05-25Put in limited support for some messages that appeared in the oldguy1-14/+96
dissector and that appear in tcpdump's IGMP dissector. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3448 f5534014-38df-0310-8fa8-9805f1628bb7
