2007-08-08add pinfo fields clnp_srcref and clnp_dstref to the clnp dissector, similar ↵Ulf Lamping1-0/+2
to the srcport / destport already existing. As simply using srcport / destport for this will confuse mixed protocol usage (like RFC1006 ISOonTCP), I've added explicit clnp fields. This way, protocols on top of COTP / CLNP have at least a chance to do reassembling correct. svn path=/trunk/; revision=22473

Fix compilation failures when building wireshark-0.99.6-SVN-21916 on an x86_64-unknown-linux-gnu target with gcc version 4.1.2 20070403 (Red Hat 4.1.2-8). The failures fall into two categories: (1) Casts between pointers and 32-bit integers without an intermediary cast via 'long' or 'unsigned long'. This results in a compiler warning complaining about casts between a pointer and an integer of a different size. (2) Passing values to "%lld" or similar printf-style format options that the compiler thinks are a different size. Such values need to be cast to 'long long' or 'unsigned long long'. svn path=/trunk/; revision=21975

If we turn on -pedantic, try turning on -Wno-long-long as well, so that it's not *so* pedantic that it rejects the 64-bit integral data types that we explicitly require.

2007-04-03epan/dissectors/Makefile is now building four libraries :Sebastien Tandel1-2/+3
- asn dissectors : libasndissectors.la - pidl dissectors : libpidldissectors.la - normal dissectors : libdissectors.la *and* libcleandissectors.la. I separated it in two libraries temporarily. The source files used to build libcleandissectors.la do not generate warning anymore and the -Werror is used to compile them. If we patch a dissector and it doesn't generate warning anymore, we have to move the filename dissector from DISSECTOR_SRC to CLEAN_DISSECTOR_SRC in epan/dissectors/Makefile.common. If you want to define specific cflags for one library type, let's say pidl, you may define libpidldissectors_la_CFLAGS. svn path=/trunk/; revision=21324

2006-08-10Neil Piercy:Jörg Mayer1-0/+1
I've just had a bug in one of our private dissectors which meant that the handle passed to call_dissector was null. This seemed to give varying behavior - on some Windows installations it hit wireshark's in-built exception handling, and displayed that the dissector had an error (correct), but on some installations it just crashed wireshark (not helpful). I _think_ the difference was whether MSVC was installed or not, but on a sample of only 3 machines. Should call_dissector include explicit null handle checks, and if so, should it:- a) g_assert - the simple patch attached b) fallback to doing a data decode (as disabled protocols do) c) try to invoke the wireshark exception handling for the packet Or is the correct answer none of the above - the exception handler should already cope ? svn path=/trunk/; revision=18869

2005-09-11Replace tvb_memcpy() calls that extract IPv4 addresses into a guint32,Guy Harris1-1/+0
and that extract IPv6 addresses into a "struct e_in6_addr", with tvb_get_ipv4() and tvb_get_ipv6() calls - except for some that we remove, by using proto_tree_add_item(), rather than replacing. Have epan/tvbuff.h include epan/ipv6-utils.h, to define "struct e_in6_addr" (not necessary to declare the tvbuff routines, but including it there means "struct e_in6_addr" is guaranteed to be defined before those declarations, so we don't get compiler complaints if we define it *after* those declarations). svn path=/trunk/; revision=15758

2005-05-11Some applications do very naughty things like reusing a port for a different ↵Ronnie Sahlberg1-3/+28
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

2005-03-23Add a "cleanup_dissection()" routine, intended to free up dataGuy Harris1-0/+14
structures allocated by a dissection. Currently, it's the same as "init_dissection()", but they should be split with "init_dissection()" allocating the initial data structures and "cleanup_dissection()" freeing them and *not* reallocating the initial data structures.
