2004-01-22Use the length field in the UDP header:guy1-2/+2
if it's < 8, don't dissect anything past the length field (the length must be >= 8); otherwise, if it's less than the data or reported length from the tvbuff, use the length from the header; otherwise, don't checksum the packet (if it's greater than the reported length, and the packet isn't fragmented, we should somehow report that as an error). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@9782 f5534014-38df-0310-8fa8-9805f1628bb7

2003-12-30Export a "dissect_tcp_payload()" routine from the TCP dissector, for useguy1-5/+15
by pass-through proxying dissectors such as the SOCKS dissector; it does the work of processing a TCP segment, including desegmentation. Export the "next sequence number" value to subdissectors, so they can use it when calling "dissect_tcp_payload()". Use that in the SOCKS dissector. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@9489 f5534014-38df-0310-8fa8-9805f1628bb7

2003-11-08"decode_tcp_ports()" is for use by protocols that proxy transport-layerguy1-2/+2
packets/sessions, e.g. MSProxy and SOCKS. It should not cause any of the TCP-specific stuff such as sequence number analysis or PDU tracking to be done. (Actually, MSProxy and SOCKS should offer desegmentation services *themselves* and do their *own* PDU tracking, rather than just passing stuff on to "decode_tcp_ports()", but that's another matter.) Make "tcp_tree" once again be a local variable to "dissect_tcp()", and pass it as an argument to those functions that use it. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8912 f5534014-38df-0310-8fa8-9805f1628bb7
2003-10-15Put back a missing comment.guy1-11/+14
Get rid of some extra blanks at the end of the text for some protocol tree items. Use %u, not %d, to format unsigned quantities. Make the "Client Authentication Methods" item's length cover all the authentication methods, not just the count of methods. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8709 f5534014-38df-0310-8fa8-9805f1628bb7

When a socks connection was used to create a second socks connection the socks dissector would be called recursively until a heap overflow occurred. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8487 f5534014-38df-0310-8fa8-9805f1628bb7
2003-04-23Update to TCP to handle hints from dissectors where the next PDU may start.sahlberg1-2/+2
ONCRPC dissector updated to provide hint to TCP where the next RPCoverTCP PDU starts as example. Trivial updates to the other TCP based protocols required to amke them handle this as well. See the updates to packet-rpc.c as an example. This is enabled by activating tcp analysis and provides hints to TCP to know where PDUs starts when not aligned to the start of the segment. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@7543 f5534014-38df-0310-8fa8-9805f1628bb7

2002-08-28Removed trailing whitespaces from .h and .c files using thejmayer1-96/+96
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.hjmayer1-11/+3
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

dftest.c: Remove #if-0-ed includes packet-ieee80211.c, packet-wtls.c, packet-afp.c, packet-wsp.c, packet-wtp.c, ethereal_gen.py: Remove redundant include varargs (already in snprintf.h, and required only for snprintf.h) Remove unused include of snprintf.h from files not using "snprintf()". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5889 f5534014-38df-0310-8fa8-9805f1628bb7
2002-06-07Don't call "tvb_strsize(tvb, offset)" if we know there's nothing *at*guy1-6/+15
"offset". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5650 f5534014-38df-0310-8fa8-9805f1628bb7
2002-06-07Use "tvb_memcpy()" rather than "strncpy()" with a "tvb_get_ptr()"guy1-7/+6
argument to copy a counted string, and use "tvb_strsize()" rather tan "strlen()" with a "tvb_get_ptr()" argument to get the length of a null-terminated string, so that we throw an exception if we go past the end of the tvbuff, rather than processing bytes past the end. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5649 f5534014-38df-0310-8fa8-9805f1628bb7
2002-04-14From Joerg Mayer:guy1-2/+2
Declares some variables static. Creates a new include file packet-rsvp.h, and make use of it (change some extern decls to #inlcude). Move the file packet-pgm.h into packet-pgm.c as it is not used by anything outside packet-pgm.c. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5162 f5534014-38df-0310-8fa8-9805f1628bb7
2002-04-11From Joerg Mayer: get rid of some unused arguments, and make someguy1-15/+15
routines not used outside the file in which they're defined static. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5144 f5534014-38df-0310-8fa8-9805f1628bb7
2002-03-09Fix some "proto_tree_add_uint()" and "proto_tree_add_uint_hidden()"guy1-5/+6
calls that passed TRUE or FALSE, rather than an integer value, as the last argument. A SOCKS command is one byte, so make the "socks.command" field an FT_UINT8. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4904 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-24Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inguy1-7/+6
arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls that add FT_NONE or FT_PROTO items to the protocol tree, with -1. Replace some calls to "tvb_length()" or "tvb_length_remaining()" with calls to "tvb_reported_length()" and "tvb_reported_length_remaining()", as those give the actual length of the data in the packet, not just the data that happened to be captured. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4605 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-21Include files from the "epan" directory and subdirectories thereof withguy1-5/+5
"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
2001-12-11Fixed the response code display for version 5 socks per Mark S. Allen.jfoster1-25/+73

2001-12-10Move the pointer to the "column_info" structure in the "frame_data"guy1-37/+37
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()"guy1-3/+2
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

2001-11-27Change "conversation_set_dissector()" to take a dissector handle, ratherguy1-3/+12
than a pointer to a dissector function, as an argument. This means that the conversation dissector is called through "call_dissector()", so the dissector itself doesn't have to worry about checking whether the protocol is enabled or setting "pinfo->current_proto", so get rid of the code that does that in conversation dissectors. Also, make the conversation dissectors static. Get rid of some direct calls to dissectors; replace them with calls through handles, and, again, get rid of code to check whether a protocol is enabled and set "pinfo->current_proto" where that code isn't needed. Make those dissectors static if they aren't already static. Add a routine "create_dissector_handle()" to create a dissector handle without registering it by name, if the dissector isn't used outside the module in which it's defined. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4281 f5534014-38df-0310-8fa8-9805f1628bb7
2001-11-21Remove the global packet_info called "pi". Dissectors now onlygram1-2/+2
access their own "pinfo". A packet_info is stored in epan_dissect_t, which is created for the dissection of a single packet. GUI functions which need to access the packet_info of the currently selected packet used to use "pi"; now they use cfile.edt->pi. cfile's "edt" member is the epan_dissect_t of the currently-selected packet. The functionality of blank_packetinfo() was moved into dissect_packet(), as that's the only place that called blank_packetinfo(), after a spurious call to blank_packetinfo() was removed from packet_list_select_cb(). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4246 f5534014-38df-0310-8fa8-9805f1628bb7

2001-10-30IPv4 addresses should be entered in host byte order, not forcedguy1-33/+44
little-endian byte order. Use "proto_tree_add_item()" wherever possible. Get rid of line commented out with a C++ comment, as not all C compilers accept C++ comments. Don't put the user name into the protocol tree if it's not there (we really should do TCP segment reassembly for this, but this is at least a good first cut). When checking whether data exists in the packet, use "tvb_offset_exists()", don't compare the offset in the tvbuf with "pinfo->len" - "pinfo->len" is the length of the entire packet, not of the tvbuff. Fix some references to "pi" to refer to "*pinfo" instead. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4108 f5534014-38df-0310-8fa8-9805f1628bb7

2001-09-03Instead of having a single datum attached to a conversation, have a listguy1-17/+16
of protocol-id-plus-datum pairs, so that multiple protocols can attach information to the same conversation. Dissectors that attach information to a conversation should not assume that if they find a conversation it has one of its data attached to it; the conversation might've been created by another dissector. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3901 f5534014-38df-0310-8fa8-9805f1628bb7

2001-01-10Change from Jeff Foster to keep the dissector from crashing if theguy1-4/+15
conversation it found has no data associated with it; this is a workaround for a problem that shows up if a conversation is between two ports both of which have protocols associated with them - in that case, frames going in one direction might be dissected by one of those dissectors, and frames going in the other direction might be dissected by the other dissector, causing untold confusion. We really need to associate dissectors with conversations as soon as the conversation is created, so that all packets will be handled by the same dissector. (The SOCKS dissector now does that.) git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2862 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",guy1-2/+3
"{old_}heur_dissector_add()", "{old_}conv_dissector_add()", and "register_dissector()", so that an entry in those tables has associated with it the protocol index of the protocol the dissector handles (or -1, if there is no protocol index for it). This is for future use in a number of places. (Arguably, "proto_register_protocol()" should take a dissector pointer as an argument, but 1) it'd have to handle both regular and heuristic dissectors; 2) making it take either a "dissector_t" or a union of that and a "heur_dissector_t" introduces some painful header-file interdependencies so I'm punting on that for now. As with other Ethereal internal APIs, these APIs are subject to change in the future, at least until Ethereal 1.0 comes out....) git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2849 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-03Have "proto_register_protocol()" build a list of data structures forguy1-2/+2
protocols, in addition to adding structures to the list of filterable fields. Give it an extra argument that specifies a "short name" for the protocol, for use in such places as pinfo->current_proto; the dialog box for constructing filters; the preferences tab for the protocol; and so on (although we're not yet using it in all those places). Make the preference name that appears in the preferences file and the command line for the DIAMETER protocol "diameter", not "Diameter"; the convention is that the name in question be all-lower-case. Make some routines and variables that aren't exported static. Update a comment in the ICP dissector to make it clear that the dissector won't see fragments other than the first fragment of a fragmented datagram. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2810 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-19For each column, have both a buffer into which strings for that columnguy1-4/+4
can be put, and a pointer to the string for the column, which might or might not point to that buffer. Add a routine "col_set_str()", which sets the string for the column to the string passed to it as an argument; it should only be handed a static string (a string constant would be ideal). It doesn't do any copying, so it's faster than "col_add_str()". Make the routines that append to columns check whether the pointer to the string for the column points to the buffer for the column and, if not, copy the string for the column to the buffer for the column so that you can append to it (so you can use "col_set_str()" and then use "col_append_str()" or "col_append_fstr()"). Convert a bunch of "col_add_str()" calls that take a string constant as an argument to "col_set_str()" calls. Convert some "col_add_fstr()" calls that take a string constant as the only argument - i.e., the format string doesn't have any "%" slots into which to put strings for subsequent arguments to "col_set_str()" calls (those calls are just like "col_add_str()" calls). Replace an END_OF_FRAME reference in a tvbuffified dissector with a "tvb_length(tvb)" call. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2670 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-18Tvbuffify the IP, ICMP, TCP, UDP, OSI CLNP, OSI COTP, OSI CLTP, and OSIguy1-3/+7
ESIS dissectors. Register the IP dissector and have dissectors that call it directly (rather than through a port table) call it through a handle. Add a routine "tvb_set_reported_length()" which a dissector can use if it was handed a tvbuff that contains more data than is actually in its part of the packet - for example, handing a padded Ethernet frame to IP; the routine sets the reported length of the tvbuff (and also adjusts the actual length, as appropriate). Then use it in IP. Given that, "ethertype()" can determine how much of the Ethernet frame was actually part of an IP datagram (and can do the same for other protocols under Ethernet that use "tvb_set_reported_length()"; have it return the actual length, and have "dissect_eth()" and "dissect_vlan()" use that to mark trailer data in Ethernet II frames as well as in 802.3 frames. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2658 f5534014-38df-0310-8fa8-9805f1628bb7

2000-08-21Change from Andreas Sikkema to change the "old" and "new" members of theguy1-3/+2
"dissector" union in the "conversation_t" structure to "old_d" and "new_d", to avoid using a C++ reserved word. Add "old_conversation_set_dissector()" and "conversation_set_dissector()" routines to set the dissector for a conversation, to hide the details of how that's done (e.g., details such as whether there's a union at all - eventually, when all dissectors have been tvbuffified, there won't be a need for the union - and what the names of the union members are, and so on). Convert all dissectors to use those routines (they had to be changed anyway, due to the name change). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2324 f5534014-38df-0310-8fa8-9805f1628bb7
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsdeniel1-1/+2
the following: It is now possible to enable/disable a particular protocol decoding (i.e. the protocol dissector is void or not). When a protocol is disabled, it is displayed as Data and of course, all linked sub-protocols are disabled as well. Disabling a protocol could be interesting: - in case of buggy dissectors - in case of wrong heuristics - for performance reasons - to decode the data as another protocol (TODO) Currently (if I am not wrong), all dissectors but NFS can be disabled (and dissectors that do not register protocols :-) I do not like the way the RPC sub-dissectors are disabled (in the sub-dissectors) since this could be done in the RPC dissector itself, knowing the sub-protocol hfinfo entry (this is why, I've not modified the NFS one yet). Two functions are added in proto.c : gboolean proto_is_protocol_enabled(int n); void proto_set_decoding(int n, gboolean enabled); and two MACROs which can be used in dissectors: OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree) CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree) See also the XXX in proto_dlg.c and proto.c around the new functions. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2267 f5534014-38df-0310-8fa8-9805f1628bb7
