2003-12-26Check that the length of an AVP is >= 6, not just that it's non-zero.Guy Harris1-3/+3
svn path=/trunk/; revision=9449
2003-01-14Set the length of the L2TP tvbuff based on the length in the L2TPGuy Harris1-13/+21
header, if present. Don't explicitly base the length of the subset we hand to the PPP dissector on the length in the header, as it might not be present; instead, just use -1 for the lengths, as we set the length of our tvbuff if there's a length in the L2TP header. Set the length of the L2TP top-level protocol item for data packets, so it covers the L2TP header but not the packet data. Don't put a padding item into the tree if there's no padding. svn path=/trunk/; revision=6922
2002-12-11From Andreas Trauer: dissect the L2TP AVPs Initial Received LCP CONFREQ,Guy Harris1-30/+32

2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer1-9/+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. svn path=/trunk/; revision=5932

2002-03-09Fix some "proto_tree_add_uint()" and "proto_tree_add_uint_hidden()"Guy Harris1-3/+3
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. svn path=/trunk/; revision=4904
2002-01-21Include files from the "epan" directory and subdirectories thereof withGuy Harris1-3/+3
"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/"). svn path=/trunk/; revision=4586
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-9/+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. svn path=/trunk/; revision=4370
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris1-3/+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. svn path=/trunk/; revision=4308

2001-03-30Call the dissector for PPP-in-HDLC-like-framing (RFC 1662) theGuy Harris1-5/+5
"ppp_hdlc" dissector, and call the dissector for "raw" PPP (just RFC 1661, no HDLC encapsulation) the "ppp" dissector. Have the common routine used by both those dissectors take the offset in the tvbuff of the PPP protocol field as an argument, rather than assuming that the protocol field begins at the beginning of the tvbuff, so we don't have to construct a new tvbuff in the PPP-in-HDLC-like-framing dissector. Use the PPP dissector, not the PPP-in-HDLC-like-framing dissector, for PPP over Frame Relay - there's no HDLC header in PPP over Frame Relay, at least according to http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t1/pppframe.htm svn path=/trunk/; revision=3208
2001-01-25Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-4/+3
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. "Tvbuffify" the Mobile IP dissector (it took old-style arguments, and then converted them into tvbuff arguments, so there wasn't much to do, other than to fix references to "fd" to refer to "pinfo->fd"). In the SCTP dissector, refer to the port type and source and destination ports through "pinfo" rather than through the global "pi", as it's a tvbuffified dissector. In the SMTP and Time Protocol dissectors, use "pinfo->match_port" rather than "TCP_PORT_SMTP" when checking whether the packet is a request or reply, just in case somebody makes a non-standard port be dissected as SMTP or Time. (Also, remove a bogus comment from the Time dissector; it was probably cut-and-pasted from the TFTP dissector.) svn path=/trunk/; revision=2938
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-2/+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....) svn path=/trunk/; revision=2849
2001-01-03Ensure that all value_string arrays end in {0, NULL}. Dissectors got awayGilbert Ramirez1-1/+2
with not terminating their arrays because they knew the limits of the value used to look up strings in the value_string array, but the dfilter_expr_dlg does not know these limits and must rely on the terminating {0, NULL} record. Also, in SNA fixed a bug in which a field should have been defined as FT_UINT8 but was defined as FT_BOOLEAN. In WTP, fixed a value string which had duplicate keys. svn path=/trunk/; revision=2817
2001-01-03Have "proto_register_protocol()" build a list of data structures forGuy Harris1-2/+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. svn path=/trunk/; revision=2810
2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-2/+2
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. svn path=/trunk/; revision=2670
2000-11-19Have the Etherenet and PPP dissectors register themselves, and haveGuy Harris1-16/+19
other dissectors call them through handles. Do the same for the "PPP payload" dissector, after tvbuffifying it. Tvbuffify the PPPoE dissector. Do the last little bit of tvbuffifying the L2TP dissector (it takes old-style arguments and immediately generates a tvbuff out of them; make it take new-style arguments). svn path=/trunk/; revision=2664
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel1-1/+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. svn path=/trunk/; revision=2267
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris1-2/+2
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()". svn path=/trunk/; revision=2218
2000-06-15Convert IPX-and-friend dissectors in packet-ipx.c to useGilbert Ramirez1-2/+2
tvbuffs. In doing so, I realied that my recommendation for using tvb_new_subset(pi.compat_top_tvb, -1, -1) was incorrect, because some dissectors (ethernet!) change pi.len and pi.cap_len. So, I have to take those two variables into account instead of using -1 and -1. So, I provide a macro called tvb_create_from_top(offset), where offset is the name of your offset variable. It is a wrapper around tvb_new_subset(). I converted the lines that followed my suggestion to use tvb_create_from_top(). In proto.c I added proto_tree_add_debug_text(proto_tree*, const char*, ...) It's much like proto_tree_add_text(), except that it takes no offset or length; it's soley for temporarily putting debug text into the proto_tree while debugging a dissector. In making sure that its use is temporary, the funciton also prints the debug string to stdout to remind the programmer that the debug code needs to be removed before shipping the code. svn path=/trunk/; revision=2068

2000-05-31Add routines for adding items to a protocol tree that take arguments ofGuy Harris1-2/+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. svn path=/trunk/; revision=2031
2000-05-11Add tvbuff class.Gilbert Ramirez1-62/+62
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
2000-04-08Move calls to "dissector_add()" out of the register routines for TCP andGuy Harris1-3/+11
UDP and into the handoff registration routines for the protocols in question. Make the dissectors for those protocols static if they're not called outside the dissector's source file. Get rid of header files if all they did was declare dissectors that are now static; remove declarations of now-static dissectors from header files that do more than just declare the dissector. svn path=/trunk/; revision=1823

2000-03-14Fix some errors discovered by making GCC do format string/argumentGuy Harris1-2/+2
cross-checking, and by replacing "proto_tree_add_item_format()" by multiple routines to add items of various types. Make the arguments of "proto_tree_add_bytes_format()" and "proto_tree_add_string_format()" that specify the bytes or the string be "const" pointers, so that one can pass a "const" pointer without complaints from the compiler. Squelch a (bogus, but the compiler isn't in a position to know that) complaint about an uninitialized variable. svn path=/trunk/; revision=1716
2000-03-12Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez1-60/+60
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
