staging: ced401: fix double unlock bug

After spin_lock() is called, all of if-else conditions in this brace
should reach the end of else and spin_unlock() must be called.
So It doesn't need to call spin_unlock() without a return statement
for handling an error.

10 years agostaging: binder: Support concurrent 32 bit and 64 bit processes.
Arve Hjønnevåg [Fri, 21 Feb 2014 22:40:26 +0000 (14:40 -0800)]
staging: binder: Support concurrent 32 bit and 64 bit processes.

For 64bit systems we want to use the same binder interface for 32bit and
64bit processes. Thus the size and the layout of the structures passed
between the kernel and the userspace has to be the same for both 32 and
64bit processes.

This change replaces all the uses of void* and size_t with
binder_uintptr_t and binder_size_t. These are then typedefed to specific
sizes depending on the use of the interface, as follows:
       * __u32 - on legacy 32bit only userspace
       * __u64 - on mixed 32/64bit userspace where all processes use the same
interface.

This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and
hooks the compat_ioctl entry for the mixed 32/64bit Android userspace.

This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for
compatability, which if set which enables the old protocol, setting
BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems.

Please note that all 64bit kernels will use the 64bit Binder ABI.

10 years agostaging: binder: Fix ABI for 64bit Android
Serban Constantinescu [Fri, 21 Feb 2014 22:40:25 +0000 (14:40 -0800)]
staging: binder: Fix ABI for 64bit Android

BC_REQUEST_DEATH_NOTIFICATION and BC_CLEAR_DEATH_NOTIFICATION were
defined with the wrong structure that did not match the code. Since a
binder pointer and handle are the same size on 32 bit systems, this
change does not affect them. The two commands claimed they were using
struct binder_ptr_cookie but they are using a 32bit handle and a pointer.

The main purpose of this patch is to add the binder_handle_cookie
struct so the service manager does not have to define its own version
(libbinder writes one field at a time so it does not use the struct).

On 32bit systems the payload size is the same as the size of struct
binder_ptr_cookie. On 64bit systems, the size does differ, and the
ioctl number does change. However, there are no known 64bit users of
this interface, and any 64bit systems will need the following patch to
run 32 bit processes anyway, so it is not expected that anyone will
ship a 64bit system without this change, so this change should not
affect any existing systems.
