I was trying to move the reassembled data from the reassembled_table to frame_data.
Moving stuff to frame_data is something that should only be done as a last resort if it's being done as part of a project to reduce memory usage. :-) *Every packet in a capture* has a frame_data structure and, at least in one test, the memory for frame_data structures was a significant contributor to Wireshark's memory usage; overall, we want to make that structure *smaller*, not *bigger.
The key to the reassembled_table is (framenum, ID). I am not able to figure out what ID is for. In a capture file, frame number itself would be unique, wouldn't it?
There can be more than one higher-level packet inside a frame (just as a higher-level packet can require more than one lower-level frame), so, no, the frame number is not necessarily unique. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
