"dissect_smb_logon()" always return TRUE, so just get rid of their return value. "call_dissector()" automatically calls the data dissector if the protocol for the dissector being called is disabled, so we don't have to check its result and call the data dissector if it returns 0. svn path=/trunk/; revision=9027
2003-11-16Export "protocol_t" as an opaque type.Guy Harris1-6/+14
Make "proto_is_protocol_enabled()" and "proto_get_protocol_short_name()" take a "protocol_t *" as an argument, so they don't have to look up the "protocol_t" - this will probably speed them up considerably, and they're called on almost every dissector handoff. Get rid of a number of "proto_is_protocol_enabled()" calls that aren't necessary (dissectors called through handles, including those called through dissector tables, or called as heuristic dissectors, aren't even called if their protocol isn't enabled). Change some direct dissector calls to go through handles. svn path=/trunk/; revision=8979

2002-01-20Allow a length of -1 to be specified when adding FT_NONE and FT_PROTOCOLGuy Harris1-2/+2
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. svn path=/trunk/; revision=4578
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-8/+8
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
2001-11-28If a request has already been processed, and we fail to find itsGuy Harris1-4/+7
"smb_saved_info_t" in the table of requests whose replies have been found, don't look it up in the table of requests whose replies have not been found - if the request in question has no reply in the capture, that may find some later frame in the same conversation with the same MID, and we don't need that information anyway - the only reason we *need* that structure is to save information in it for use when processing its reply, and we already did that the first time we processed the request. (The information for the later frame may be bad, e.g. having a null "extra_info" pointer, or having one that points to information for another request.) Arrange that we don't use the pointer to the "smb_saved_info_t" when processing a request except to save information if the request hasn't already been processed, as that pointer may not be valid if the request has already been processed, as per the above. svn path=/trunk/; revision=4292
2001-11-28Updates to transaction reassembly, from Ronnie Sahlberg.Guy Harris1-1/+3
Add some checks for null tvbuff arguments. When dissecting transaction setup, parameters, and data when we couldn't dissect it as a pipe or mailslot transaction, use the reported length of the supplied tvbuff, not the actual length, as the amount of data present. svn path=/trunk/; revision=4291

2001-11-19Make the register routines for the mailslot, pipe, browser, andGuy Harris1-2/+2

2001-11-19Pass, as the first tvbuff argument to "dissect_mailslot_smb()" andGuy Harris1-11/+14
"dissect_pipe_smb()", a tvbuff containing the setup words and the pipe/mailslot pathname, as those are arguably the part of the packet that contains the "mailslot protocol" and the "pipe protocol", as opposed to the protocol running atop mailslots or pipes. Pass a setup tvbuff to "dissect_pipe_smb()" for it to pass on to the MSRPC-over-named-pipe dissector, and have the setup tvbuff passed to it and "dissect_mailslot_smb()" contain *only* the setup words; don't extract anything other than the setup words from it. Declare "register_proto_smb_mailslot()" in "packet-smb-mailslot.h" rather than "packet-smb.c", and declare "register_proto_smb_pipe()" in "packet-smb-pipe.h" rather than "packet-smb.c". Add a protocol for MSRPC-over-named-pipes. Move the stuff to handle the FID in the setup words of MSRPC-over-named-pipe transactions out of the SMB Transaction dissector into the MSRPC dissector. Add a routine to "packet-smb.c", callable from outside "packet-smb.c", to put an "smb.fid" field into the protocol tree, and to add ", FID: XXXX" to the Info column, for use by the MSRPC-over-named-pipe dissector; use it in the SMB dissector as well, in all the places where we put a FID into the protocol tree. Move the stuff to check whether the LANMAN protocol is enabled, and to set "pinfo->current_proto" to "LANMAN" if it is, into the LANMAN API-over-named-pipe dissector out of the named pipe protocol dissector. If we didn't dissect a Transaction request or reply as a named pipe or mailslot message, put any setup words, parameters, and data it has into the protocol tree as separate items. Don't put a "Response in" item into the protocol tree for an NT Cancel request, as there are no responses to NT Cancel requests. svn path=/trunk/; revision=4221
2001-11-18Pass in the "smb_info" structure a pointer to the "smb_saved_info_t"Guy Harris1-17/+35
structure, so that it can be updated by subdissectors; this way the updates affect the structure immediately, and don't get lost if the subdissector later throws an exception. Use "tvb_reported_length()" to check for an interim mailslot reply; "tvb_length()" could give the wrong answer if a short snapshot length was given in the capture. svn path=/trunk/; revision=4218
2001-11-18Have only the request and response frame numbers, and a "void *", in anGuy Harris1-34/+20
"smb_saved_info_t". Put all the information needed to dissect NT Transaction replies, Transaction2 replies, or Transaction replies into separate data structures, allocated separately, and put a pointer to that data structure in the "void *" in question. Use the return value of "dissect_pipe_smb()" and "dissect_mailslot_smb()" to control whether to display as data the stuff those routines were asked to dissect. If we've seen a request before, but its "smb_saved_info_t" isn't in the "matched" hash table, look in the "unmatched" hash table - perhaps we haven't seen the reply yet. svn path=/trunk/; revision=4216

svn path=/trunk/; revision=3832
2001-08-05Add a request/response flag to the "struct smb_info" structure, and useGuy Harris1-2/+2
that rather than passing another copy of that flag to dissectors of particular messages. Pass that structure to the pipe subdissector by making "pi.private" point to it, rather than by passing it as an explicit argument. Change more of the if (dirn == 1) { ... } if (dirn == 0) { ... } stuff to if (dirn == 1) { ... } else { ... } and then, as per the first paragraph, check the "request" flag in the "smb_info" structure rather than checking a "dirn" flag. Set "last_transact2_command" to -1 in the "smb_request_val" structures for TRANSACTION requests, as it doesn't apply to those requests. As "dissect_transact_params()" doesn't do any work if the "TransactName" argument is null, don't bother calling it for a reply if we don't have an "smb_request_val" for the corresponding request, as that means we can't find out the value to pass as the "TransactName" argument. svn path=/trunk/; revision=3822
2001-08-01Packets sent to \MAILSLOT\LANMAN appear to be browser announcements (forGuy Harris1-5/+9
an older version of the protocol than the one for packets sent to \MAILSLOT\BROWSE), rather than being LANMAN pipe packets. svn path=/trunk/; revision=3803

Move the declaration of routines exported from "packet-smb-mailslot.c" into a "packet-smb-mailslot.h" header file, and have modules that import those routines include "packet-smb-mailslot.h" rather than declaring the routines themselves; do the same for routines exported from "packet-smb-pipe.c".

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
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel1-2/+4
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
2000-05-31Add 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 Ramirez1-7/+7
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
