2003-10-18From Emanuele Caratti:guy1-9/+108
add the dissection of RIPv2 packets with Keyed Message Disest Authentication (RFC2082); fix a small bug - the Auth entry must be the first of the RTE in a RIP packet. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8733 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-28Removed trailing whitespaces from .h and .c files using thejmayer1-9/+9
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.hjmayer1-9/+1
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
2002-04-04Put in the RFCs for RIPv1 and RIPv2.guy1-10/+49
Handle an address family of 0; that means that the address wasn't specified in the request, which is used for a "send me the whole routing table" request. Replace some "proto_tree_add_XXX" calls with "proto_tree_add_item" calls. Use FALSE, rather than TRUE, as the byte order argument in one "proto_tree_add_item" call, for consistency with other calls; the field is a string, so the byte order doesn't matter. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5099 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-24Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inguy1-2/+2
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 withguy1-2/+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
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"guy1-9/+9
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

2001-03-13Make tvb_get_ptr() return 'const guint8*', and clean up all thegram1-2/+2
usages of tvb_get_ptr(). packet-ieee80211.c still has one bad usage, in which it *does* modify the tvbuff's data. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3128 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="guy1-4/+5
statements. Move the setting of the Protocol column in various dissectors before anything is fetched from the packet, and also clear the Info column at that point in those and some other dissectors, so that if an exception is thrown, the columns don't reflect the previous protocol. Don't use col_add_fstr(..., "%s", string); Use col_add_str(..., string); as it does the same thing, but doesn't drag all the heavy *printf machinery in. Fix the DDTP dissector to set the Info column regardless of whether we're building a protocol tree or not, and to set it to "Encrypted payload" if the payload is encrypted. Also fix a typo in a field name. Register the FTP data dissector as being associated with the FTP data protocol, not the FTP protocol (the removed "CHECK_DISPLAY_AS_DATA()" call checked "proto_ftp_data", and the removed "pinfo->current_proto =" line set it to "FTP-DATA", so it should be associated with "proto_ftp_data"). Make the H1 dissector check whether the frame has at least 2 bytes in it before checking the first two bytes; heuristic dissectors must not throw exceptions until they've accepted the packet as one of theirs. Use "tvb_format_text()" rather than "tvb_get_ptr()" and "format_text()" in some dissectors where the result of "tvb_get_ptr()" is used only in the "format_text()" call. In the Quake dissector, don't check whether there are at least 4 bytes in the packet - if we return, the packet won't be dissected at all (it's not as if some other dissector will get to handle it), and, if we don't return, we'll throw an exception if there aren't at least 4 bytes in the packet, so the packet will be marked as short or malformed, as appropriate. In the RIPng dissector, associate the table of strings for the command field with the command field, so that the dissector doesn't have to format the string for the protocol tree entry itself, and so that the filter construction dialog box can let you select "Request" or "Response" from a list rather than requiring you to know the values for "Request" and "Response". Make "dissect_rpc()" static, as it's called only through a heuristic dissector list. Use "col_set_str()" to set the COL_PROTOCOL column for RPC protocols; the string used is from a table provided by the dissector, and is a string constant. Don't format the Info column for WSP into a buffer and then format that buffer into the column with "%s" - "col_add_fstr()" can do the formatting for you, without having to allocate your own buffer (or run through the *printf machinery twice). Don't fetch fields from the WTP packet until you're ready to use them, so that you don't throw an exception before you even set the Protocol column or clear the Info column. Use "pinfo->destport", not "pi.destport", in the Zebra dissector when checking whether the packet is a request or reply, and do the check by comparing with "pinfo->match_port" rather than TCP_PORT_ZEBRA (so that if the dissector is ever registered on another port, it still correctly determines whether the packet is a request or reply - the Network Monitor HTTP dissector has port 80 wired into its brain, which is a bit irritating if you're trying to get it to dissect HTTP proxy traffic on port 3128 or proxy administration UI traffic on port 3132). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2931 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",guy1-2/+2
"{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 forguy1-14/+15
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
2000-12-27Tvbuffify the RIP and OSPF dissectors.guy1-98/+103
Change them to use facilities in Ethereal that were probably not present when they were originally written, e.g. routines to fetch 24-bit integers and to dump a bunch of raw bytes in hex. Redo them to extract data from the packet as they dissect it, rather than extracting an entire data structure at once; that way, it may be able to dissect a structure not all of which is in the packet. Dissect a bit more of the type-of-service metrics etc. in OSPF packets. Make "tvb_length_remaining()" return a "gint", not a "guint"; it returns -1 if the offset is past the end of the tvbuff. Add a "tvb_reported_length_remaining()" routine, similar to "tvb_length_remaining()". Use it instead of just subtracting an offset from "tvb_reported_length()". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2787 f5534014-38df-0310-8fa8-9805f1628bb7

2000-08-13Add the "Edit:Protocols..." feature which currently only implementsdeniel1-1/+3
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
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)guy1-5/+5
dissectors to be registered as dissectors for particular ports, registered as heuristic dissectors, and registered as dissectors for conversations, and have routines to be used both by old-style and new-style dissectors to call registered dissectors. Have the code that calls those dissectors translate the arguments as necessary. (For conversation dissectors, replace "find_conversation_dissector()", which just returns a pointer to the dissector, with "old_try_conversation_dissector()" and "try_conversation_dissector()", which actually call the dissector, so that there's a single place at which we can do that translation. Also make "dissector_lookup()" static and, instead of calling it and, if it returns a non-null pointer, calling that dissector, just use "old_dissector_try_port()" or "dissector_try_port()", for the same reason.) This allows some dissectors that took old-style arguments and immediately translated them to new-style arguments to just take new-style arguments; make them do so. It also allows some new-style dissectors not to have to translate arguments before calling routines to look up and call dissectors; make them not do so. Get rid of checks for too-short frames in new-style dissectors - the tvbuff code does those checks for you. Give the routines to register old-style dissectors, and to call dissectors from old-style dissectors, names beginning with "old_", with the routines for new-style dissectors not having the "old_". Update the dissectors that use those routines appropriately. Rename "dissect_data()" to "old_dissect_data()", and "dissect_data_tvb()" to "dissect_data()". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2218 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-31Add routines for adding items to a protocol tree that take arguments ofguy1-2/+2
a particular type, rather than taking a varargs list, along the lines of the "proto_tree_add_XXX_format()" routines. Replace most calls to "proto_tree_add_item()" and "proto_tree_add_item_hidden()" with calls to those routines. Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to "proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()" routines that don't take the item to be added as an argument - instead, they fetch the argument from the packet whose tvbuff was handed to them, from the offset handed to them. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2031 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-11Add tvbuff class.gram1-16/+16
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1939 f5534014-38df-0310-8fa8-9805f1628bb7
2000-04-14RFC 1058, on RIP V1, says:guy1-2/+10
Specific queries and debugging requests may be sent from ports other than 520, but they are directed to port 520 on the target machine. and RFC 2453, on RIP V2, says: Specific queries may be sent from ports other than the RIP port, but they must be directed to the RIP port on the target machine. so there is no requirement that RIP packets have 520 as both source and destination port numbers. It's therefore OK to register it as the dissector for UDP port 520 - no need to handle it specially in the UDP dissector as a reminder to make it check both source and destination ports - so we do so. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1855 f5534014-38df-0310-8fa8-9805f1628bb7
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withguy1-4/+12
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1043 f5534014-38df-0310-8fa8-9805f1628bb7
1999-08-26Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or toguy1-3/+3

1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowgram1-36/+33
reference the protocol tree with struct proto_tree and struct proto_item objects.
