bpf - Berkeley Packet Filter interface for CHICKEN Scheme.

Age	Commit message (Collapse)	Author
2016-03-04	Apparently even nonblocking reads are blocking in a way(?!) and we will get ↵	Peter Bex
	multiple packets off the iface. The actual packet data is preceded by a "struct bpf_hdr" header we need to skip. Because of that, passing a raw buffer is not going to be very useful, so bpf-read-packet! can be removed from the API.
2016-03-04	Switch to nonblocking I/O and get rid of bpf-read-timeout since it is ↵	Peter Bex
	useless for nonblocking I/O...
2016-03-04	Make ioctl interface a little less verbose by generating some stuff that's ↵	Peter Bex
	always the same in a macro. This should also inline it
2016-03-04	Implement filter setting	Peter Bex

2016-03-04	Add stats procedure	Peter Bex

2016-03-04	Implement timeout IOCTL	Peter Bex

2016-03-04	Expose flush ioctl and add listing/getter/setter of datalink types.	Peter Bex
	For now, we just work with the underlying integer values. Maybe later we'll translate these to symbols?
2016-03-04	Don't try to print details of closed BPF objects	Peter Bex

2016-03-04	Implement buffer-length option, and export the interface setting/getting ↵	Peter Bex
	procedures as well as the procedure to retrieve the buffer length. Switch to c-pointer and use LOCATION to get pointers from scheme objects.
2016-03-04	Add setup file, copyright and BPF device interface	Peter Bex
	Add an initial opaque record type holding a connection to the BPF device. At least this now allows us to open a BPF device onto a network interface and request which network device we're connected to.
