Study the file format of usbdump, declare usbdump_read_record to read the packet record

Implement usbdump_open for checking if an open file is of usbdump format Start learning wiretap library of Wireshark, declare and register key routines: usbdump_open, usbdump_read, usbdump_seek_read These documents can help others understand the code, thereby improve its maintainability. This should include the structure specification of the usbdump file-format, code organization, main data structure specification, etc. Necessary documentation for the patch.The entire code base for patching Wireshark to support the usbdump file-format, this includes patches to The wiretap library, dissector, filters, etc.

The wiretap library handles a number of formats it supports, by hacking into it we can add support for the usbdump file-format. Besides, the usbdump program itself can parse its output file through ‘-r’ option and the source code will also be a wonderful reference.Īdd support to Wireshark’s wiretap library. The usbdump use the Berkeley Packet Filter (BPF) behind the scene, BPF and its packet structure is well-documented. By diving into Wireshark’s wiretap library, which handles a number of formats it supports, we can add support for usbdump file-format. Currently Wireshark does not support usbdump file-format of FreeBSD. Wireshark is a widely used network packet analyzer which is capable of capturing network packets and displaying the packet data as detailed as possible. usbdump is the userland program of FreeBSD USB subsystem, which allows capturing packets that go through each USB host. This project will add support for usbdump file-format to Wireshark.

Add support for usbdump file-format to Wireshark.
