FreeBSD's libusb has three components: libusb01, libusb10, and libusb20. libusb20 handles communication with character devices. We now requires a backend context for libusb20. The backend context contains contains the capsicumized usbctrl fd and usb directory (/dev/usb) fd so that the library user can enter the capiblity mode safely while using libusb. libusb10 is updated to support capabilities via a context option. Since libusb allows general read/write access, we preserve all possible capabilities when passing backend context to libusb20. It is the responsibility of the libusb user to call cap_enter() at an appropriate time. All base system tools using libusb and libusb20 have been updated to support Capsicum.

This directory tree contains tools used for the maintenance and testing of FreeBSD. There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs. Please read the README files in the subdirs for further information.
