Rename the arguments and flags for the conversation routines, so as not to imply that 1) conversations have source and destination addresses and ports - they don't (if they did, they'd be monologues, not conversations), they just have two address/port pairs for the two endpoints, with one or more of the address or port in the second pair possibly being wildcarded; 2) the first and second address or port argument to "find_conversation()" or "try_conversation_dissector()" have anything to do with the first or second address/port pair in a conversation - they don't, the two arguments to those routines are matched against *both* address/port pairs for a conversation; as otherwise people might think that they need to add flags to wildcard the first arguments "conversation_new()" or "find_conversation()" (they don't, they just have to pass the non-wildcarded address/port first and then pass the wildcarded one, even if that means passing the destination first and source second). svn path=/trunk/; revision=3537

Make the SNMP dissector use the ASN.1 code, rather than the SNMP library code, to dissect SNMP PDUs; use the SNMP library code only to translate OIDs into strings. Put into the ASN.1 code an annoying hack to cope with the fact that UCD SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of "u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef "subid_t" appropriately depending on the SNMP library you have. Eventually, we should be able to use "libsmi" instead of a full-blown SNMP library, and thus possibly work around various aggravations with the SNMP libraries. svn path=/trunk/; revision=1280

"asn1_octet_string_decode()" sets the pointer to the raw octets to NULL if the octet string is zero-length; if the octets are to be interpreted as a character string, we have to check for a null pointer and replace it with a pointer to a null string. svn path=/trunk/; revision=2102

Make the SNMP dissector use the ASN.1 code, rather than the SNMP library code, to dissect SNMP PDUs; use the SNMP library code only to translate OIDs into strings. Put into the ASN.1 code an annoying hack to cope with the fact that UCD SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of "u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef "subid_t" appropriately depending on the SNMP library you have. Eventually, we should be able to use "libsmi" instead of a full-blown SNMP library, and thus possibly work around various aggravations with the SNMP libraries. svn path=/trunk/; revision=1280

Added Didier Jorand's dissect_snmp routine. This is only compiled in if you have the UCD or CMU SNMP library available. If you have the SNMP library but do not with to have SNMP support, use the ./configure --disable-snmp option. Otherwise 'configure' finds the SNMP library and uses it. svn path=/trunk/; revision=281

From Gisle Vanem: * Added a new function get_file_in_temp() to epan/filesystem.c. This because of asn1.dll plugin which had code to write to a log-file "c:\temp\ethereal.log". I feel this patch makes this safer; I don't even have a c:\temp dir. * Patched packet-asn1.c to use get_file_in_temp(). * Added some #undef to packet-snmp.c to silence gcc. * Changed "%u" -> "%lu" formats in util.c Rename get_file_in_temp() to get_tempfile_path() to match other function names. svn path=/trunk/; revision=8859

Make the SNMP dissector use the ASN.1 code, rather than the SNMP library code, to dissect SNMP PDUs; use the SNMP library code only to translate OIDs into strings. Put into the ASN.1 code an annoying hack to cope with the fact that UCD SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of "u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef "subid_t" appropriately depending on the SNMP library you have.

In packet-cops.c use proto_item_append_text() instead of creating a separate buffer. Fixes the current Buildbot failure. Don't let the sprint_realloc_* functions reallocate ep_allocated memory.

Rename "format_value()" to "format_var()", and have it dynamically allocate the buffer into which it formats the variable value, and return that value. This 1) makes it more closely resemble the formatting routine in the libsmi-based "packet-snmp.c" under development; 2) makes it less likely to overrun the buffer (we can't be certain how long the string "sprint_value()" generates will be, but we can make a reasonable guess as to the maximum size based on the type and size of the object we're formatting). When *not* using "-lsnmp", dynamically allocate the buffers into which we format octet strings and OID values, based on the size of the object we're formatting, so that we don't overrun the buffer. svn path=/trunk/; revision=2091

just to get things straight: a dissector should *never* do any g_assert() calls! in a simple approach, I've replaced all g_assert() and g_assert_not_reached() calls by their exception throwing counterparts DISSECTOR_ASSERT() and DISSECTOR_ASSERT_NOT_REACHED() this will replace application crash by showing a dissector bug, which is the desired behaviour there were some g_assert calls in the protocol registering functions, which might not be acting as expected now, but to be able to simply search for g_assert in the future I've replaced that calls too one g_assert remained, the one when someone throws an unknown exception "into" packet_frame.c, but IMHO this one should remain. svn path=/trunk/; revision=14608

Use "val_to_str()", rather than "get_XXX()" routines, to map SNMP versions, PDU types, error statuses, and trap types to strings. Set the protocol column to "SNMP", and set the info column to an error message if the parse fails (rather than printing a message to the standard error) and to the PDU type if it succeeds. svn path=/trunk/; revision=305

Make the SNMP dissector use the ASN.1 code, rather than the SNMP library code, to dissect SNMP PDUs; use the SNMP library code only to translate OIDs into strings. Put into the ASN.1 code an annoying hack to cope with the fact that UCD SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of "u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef "subid_t" appropriately depending on the SNMP library you have. Eventually, we should be able to use "libsmi" instead of a full-blown SNMP library, and thus possibly work around various aggravations with the SNMP libraries. svn path=/trunk/; revision=1280

Added Didier Jorand's dissect_snmp routine. This is only compiled in if you have the UCD or CMU SNMP library available. If you have the SNMP library but do not with to have SNMP support, use the ./configure --disable-snmp option. Otherwise 'configure' finds the SNMP library and uses it. svn path=/trunk/; revision=281

Make the SNMP dissector use the ASN.1 code, rather than the SNMP library code, to dissect SNMP PDUs; use the SNMP library code only to translate OIDs into strings. Put into the ASN.1 code an annoying hack to cope with the fact that UCD SNMP makes an OID out of "u_long"s whilst CMU SNMP makes it out of "u_int"s - have the ASN.1 code make it out of "subid_t"s, and typedef "subid_t" appropriately depending on the SNMP library you have. Eventually, we should be able to use "libsmi" instead of a full-blown SNMP library, and thus possibly work around various aggravations with the SNMP libraries. svn path=/trunk/; revision=1280

Some applications do very naughty things like reusing a port for a different protocol during different stages of an application cycle. This is very naughty and will cause problems when we have assigned a dissector to a dynamic port using conversation_set_dissector(). To make ethereal handle this case I have changed the try_conversation_dissector() to allow it to fail and return 0, meaning yes there is indeed a protocol registered for this conversation but that protocol rejected this packet. (which only happens for "new" style dissectors, "old" style dissectors will never reject a packet that way) When this happens the decode_udp_port() helper will still allow other dissectors to be tried, in the hope that the conversation is now used for some other protocol and thus someone else might be able to decode the packet. Update SNMP and TFTP dissectors to check that even if there already is a conversation but that conversation does NOT have snmp/tftp registered as the dissector for it, then create a new conversation anyway and attach the proper dissector. Since ethereal keeps track of which frame number a conversation started in, this actually works really well. svn path=/trunk/; revision=14345

From Jon Ringle: 1) Added a setup_frame parameter to conversation_t 2) Used the conversation_t next to maintain a list of conversations with the same src/dest tuple but different setup_frame number. 3) Changed the signature of find_conversation() and conversation_new() to pass in the frame number. 4) Adjusted packet-sdp to select RTP conversation if both m=audio and m=image are present, and T.38 conversation if only m=image is present. I expect that RTP/T.38 dissecting to be better, but I don't have a way to generate T.38 packets. svn path=/trunk/; revision=13243
2005-02-02 20:07:03 +00:00
conversation = conversation_new(pinfo->fd->num, &pinfo->src, &pinfo->dst, PT_UDP,
Instead of having a single datum attached to a conversation, have a list 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. svn path=/trunk/; revision=3901
2001-09-03 10:33:12 +00:00
pinfo->srcport, 0, NO_PORT2);
Change "conversation_set_dissector()" to take a dissector handle, rather 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. svn path=/trunk/; revision=4281
2001-11-27 07:13:32 +00:00
conversation_set_dissector(conversation, snmp_handle);
Don't require that all SNMP packets go to or from the SNMP port - the SNMP request would, but an SNMP reply can come back from another port. Instead, when an SNMP request is seen, create a conversation with a wildcard port, if one doesn't already exist, and make its dissector the SNMP dissector. svn path=/trunk/; revision=2526

As per Nathan Leulinger's suggestion, have a stub SNMP dissector if there are no SNMP libraries to use in a real dissector; this means that other dissectors don't have to care if there are SNMP libraries, they can just call "dissect_snmp()" - and this also simplifies "Makefile.am" and "configure.in" a bit, as they just treat "packet-snmp.c" and "packet-snmp.h" the same way they treat other dissector source files. svn path=/trunk/; revision=1214
