Ethereal-dev: Re: [Ethereal-dev] Patch to packet-bacapp.c

Hi list, please have a closer look at this patch to packet-bacapp.c.I have added packet-bacapp.h with descriptions conforming to doxygen too. It will be used by packet-bacapp.c.
Check in if possible. best regards Herbert Lischka
Guy Harris wrote:Checked in....and backed out, because its heavy use of recursion instead of iteration means that malformed packets can cause it to overflow the process's stack and crash.
done and added some checks to avoid endless loops on malformed packages
Please fix that, and also:
1) fix the problems noted in Ronnie Sahlberg's and my mail messages;
done
2) don't use "match_strval()" to convert numerical values to strings, use "val_to_str()", as a malformed packet could mean that there is no string corresponding to the value;
done
3) don't just cast length values to "guint8" if they might be larger than 8 bits;
done
4) make the length field in the tag/class/LTV value 32 bits, as the BACnet spec I have seems to say it can't be larger than 2^32-1 - and make the tag parsing code handle the "length is > 65535" case;
done
5) don't use "//" comments - not all compilers Ethereal is built with support them;
done
6) make all routines not used outside packet-bacapp.c static.
done
You might want to consider modeling the BACnet application layer dissector after the packet-ber.c dissector and dissectors using it, e.g. with SEQUENCE, SEQUENCE OF, and CHOICE values dissected with a table handed to a generic SEQUENCE, SEQUENCE OF, or CHOICE dissector.
Sorry, but please have a closer look at chapter 20. ENCODING BACnet PROTOCOL DATA UNITS. I found a lot of "-- only if....." in chapter 21. FORMAL DESCRIPTION OF APPLICATION PROTOCOL DATA UNITS and that's not really helpful...
