okay, so as I understand it, basically you have keeping the name that was in the library in a structure in lib cap.
No, the name was never in a library; "struct canusb_t" is a structure in the pcap-canusb-linux.c module. The field was removed, but was needed; Jakub's patch put in another field to hold the relevant part of the device name. (Perhaps all that's really needed is the numerical value of the field, if there's a libusb call to get the numerical value of the property in question.)
looks like all the tests now fail with: reading from file spb.pcap, link-type EN10MB (Ethernet) tcpdump: direction is not supported on save files
Not on my machine, with a recent "git pull"ed version of the libpcap and tcpdump trunks and 1.3/4.3 branches. In the libpcap trunk, the only message I can find like that is "Setting direction is not supported on save files", which is returned for a pcap_setdirection() call if you're reading from a savefile. I can't find any such message in the tcpdump trunk, nor can I find any calls to pcap_setdirection() there either, so I'm not sure where that message is coming from; try doing a "make clean" in the libpcap directory and rebuild both libpcap and tcpdump (the internal layout of the pcap_t structure changed, and perhaps there was no .devel file to cause dependencies to be generated and not all files that included pcap-int.h got rebuilt, so that perhaps when tcpdump was calling something other than pcap_setdirection() the savefile setdirection function was being called). _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
