This is the second version of a patch which demonstrates the possibility of using adbd (Android Debug Bridge daemon) with a generic FunctionFS gadget instead of a custom adb usb gadget in the Linux kernel. It contains changes introduced after Benoit's review - thank you Benoit. The patch adds a new usb access layer to adbd using FunctionFS. The former usb access method is still available. The method is chosen at runtime depending if /dev/usb-ffs/adb/ep0 or /dev/android_adb is accessible. How to use on the target device: $ insmod g_ffs.ko idVendor=<vendor ID> iSerialNumber=<some string> $ mount -t functionfs adb /dev/usb-ffs/adb -o uid=2000,gid=2000 $ ./adbd This patch requires a patch to bionic which adds <linux/usb_functionfs.h> which is an exact copy of the relevant file in the linux kernel.

The system/ directory is intended for pieces of the world that are the core of the embedded linux platform at the heart of Android. These essential bits are required for basic booting, operation, and debugging. They should not depend on libraries outside of system/... (some of them do currently -- they need to be updated or changed) and they should not be required for the simulator build. The license for all these pieces should be clean (Apache2, BSD, or MIT). Currently system/bluetooth/... and system/extra/... have some pieces with GPL/LGPL licensed code. Assorted Issues: - pppd depends on libutils for logging - pppd depends on libcrypt/libcrypto - init, linker, debuggerd, toolbox, usbd depend on libcutils - should probably rename bionic to libc
