This sure looks like a bug to me. A quick search shows at least these 18 dissectors calling it: $ grep -l proto_tree_get_parent packet-*.c packet-amr.c packet-assa_r3.c packet-dcerpc.c packet-h264.c packet-h450-ros.c packet-h450.c packet-h460.c packet-iax2.c packet-isakmp.c packet-mikey.c packet-mp4ves.c packet-q931.c packet-q932-ros.c packet-qsig.c packet-rtp.c packet-smb2.c packet-ssl.c packet-tcp.c
If things are working correctly in those dissectors, then I think it's by pure luck and the function call can simply be omitted. Either way, I think the function should be changed to implement what its proto_item_get_parent() peer implements. I would suggest filing a bug report about. Good catch. - Chris -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Eloy Paris Sent: Thursday, March 25, 2010 8:49 PM To: Developer support list for Wireshark Subject: [Wireshark-dev] proto_tree_get_parent() Is this right (from epan/proto.c): proto_item* proto_tree_get_parent(proto_tree *tree) { if (!tree) return (NULL); return (proto_item*) tree; } This basically returns the same thing that is received as a parameter. Shouldn't tree->parent be returned instead, just as proto_item_get_parent() (a few lines above in the same file) does? The weird thing is that there is code using this seemingly broken proto_tree_get_parent(). I don't know how things are working given that proto_tree_get_parent() is not really providing the parent node.
