Well, I've downloaded it.
Some comments:
1) Don't patch Makefile.in or register.c - those are generated
files. Patch Makefile.am instead - and patch Makefile.nmake, as
well. (Change the DISSECTOR_SRC list in both files.)
2) In "dissect_list()", it doesn't handle the case where
"object_type" is neither 1, 2, nor 3. Perhaps that shouldn't
happen, but it could happen, due to a buggy program, or a
corrupted packet, or some port 9999 traffic that *isn't*
Nominum Command Channel traffic.
It should probably use "proto_tree_add_text()" to add an item
that says "bogus object type" and gives the type value, or
something such as that.
3) All the cases in that first switch statement should perhaps
use offset+pos as the offset and object_size as the size.
The ones for 2 and 3 use 0 and -1, meaning they'll cover the
entire packet; do those really appear only at the *very*
beginning of the packet, and run all the way to the end?
Also, does object_size include the type or not? The later
code for type 1 uses offset+pos and object_size as the
starting offset and length, suggesting that it does.
