A * NETLIB packet starts with an eight byte header containing: * * a one-byte packet type field; * * a one-byte status field; * * a two-byte big-endian size field giving the size of the packet, * including the header; * * a two-byte big-endian channel number, used when multiple sessions * are being multiplexed on a single connection; * * a one-byte packet number, giving "the frame number of a multiplexed * message, modulo 256"; * * a one-byte window, which is the number of frames to be sent * before an acknowledgment message is received. * * followed by payload whose size is the value in the size field minus * 8. * * Microsoft Network Monitor 2.x dissects the 4 byte field (and indicates * that the one-byte last packet indicator also contains other bits). * * The TDS protocol consists of a number of protocol data units (PDUs) that * appear to be assembled from NETLIB packets, in the form of zero or more * NETLIB packets with the last packet indicator clear and a final NETLIB * packet with the last packet indicator set. The type of the TDS PDU is * specified by the packet type field of the NETLIB header (presumably that * field has the same value for all NETLIB packets that make up a TDS PDU). * * The "server response" PDU consists of a sequence of multiple items, each * one beginning with a one byte type field at the start of the PDU. Some * items are fixed length, some are variable length with a two byte size * field following the item type, and then there is TDS_ROW_TOKEN in which * size is determined by analyzing the result set returned from the server. * This in effect means that we are hopelessly lost if we haven't seen the * result set. Also, TDS 4/5 is byte order negotiable, which is specified * in the login packet. We can attempt to determine it later on, but not * with 100% accuracy. * * Some preliminary documentation on the packet format can be found at * http://www.freetds.org/tds.html * * Some more information can be found in * https://web.archive.org/web/20140611233513/http://www.sybase.com/content/1013412/tds34.pdf * https://web.archive.org/web/20140611233501/http://www.sybase.com/content/1040983/Sybase-tds38-102306.pdf * Microsoft's [MS-TDS] protocol specification * https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-tds/ * Microsoft's TDS 4.2 [MS-SSTDS] protocol specification * https://docs.microsoft.com/en-us/openspecs/sql_server_protocols/ms-sstds/ * * This document is no longer available here, and does not appear to * have been archived by the Wayback Machine: * http://download.nai.com/products/media/sniffer/support/sdos/sybase.pdf * * Much of this code was originally developed for the FreeTDS project. * http://www.freetds.org */ /* * Excerpts from Brian's posting to wireshark-dev: * * The TDS Protocol is actually a protocol within a protocol. On the outside * there is netlib which is not so much a encapsulation as a blocking of the * data, typically to 512 or 4096 bytes. Between this are the protocol data * units for TDS. Netlib packets may be split over real packets, multiple * netlib packets may appear in single real packets. TDS PDUs may be split * over netlib packets (and real packets) and most certainly can appear * multiple times within a netlib packet. * * Because of this, I abandoned my earlier attempt at making two dissectors, * one for netlib and one for TDS. Counterintuitively, a single dissector * turned out to be simpler than splitting it up. * * Here are some of the (hefty) limitations of the current code * * . I probably could have used the packet reassembly stuff, but I started * this at version 0.8.20, so c'est la vie. It wouldn't have covered the * netlib stuff anyway, so no big loss. * . The older two layer version of the code dissected the PDU's, but the new * version does not yet, it only labels the names. I need an elegant way to * deal with dissecting data crossing (netlib and tcp) packet boundaries. I * think I have one, but ran out of time to do it. * . It will only work on little endian platforms. Or rather I should say, * the client that was captured must be little endian. TDS 7.0/8.0 is * always LE; for TDS 4.2/5.0 look in the code for tvb_get_le*() functions, * there are fields in the login packet which determine byte order. * . result sets that span netlib packets are not working * . TDS 7 and 4.2 result sets are not working yet * * All that said, the code does deal gracefully with different boundary * conditions and what remains are the easier bits, IMHO. * * XXX - "real packets" means "TCP segments", for TCP. * * XXX - is it *REALLY* true that you can have more than one TDS PDU (as * opposed to more than one server response item) per NETLIB packet? Or is * all the data in a NETLIB packet put into a single TDS PDU? If so, then * we can reassemble NETLIB packets using the standard TCP desegmentation * code, and can reassemble TDS PDUs using "fragment_add_seq_check()", * and more cleanly separate the NETLIB and TDS dissectors (although the * "is this NETLIB" heuristic would have to look at TDS information past * the NETLIB header, in order to make the heuristic strong enough not * to get too many false positives; note that the heuristic should reject * any putative NETLIB packet with a length field with a value < 8). * * That would substantially clean the dissector up, eliminating most of * the per-packet data (we might still need information to handle * TDS_ROW_TOKEN), getting rid of the stuff to handle data split across * TCP segment boundaries in favor of simple reassembly code, and * fixing some otherwise nasty-looking crashing bugs. * * NOTE: we assume that all the data in a NETLIB packet *can* be put into * a single TDS PTU, so that we have separate reassembly of NETLIB * packets and TDS PDUs; it seems to work, and it really did clean stuff * up and fix crashes. */ #include "config.h" #include #include #include #include #include #include #include #include #include
