Opening the binder driver and sharing the file returned with other processes (e.g. by calling fork) can crash the kernel. Prevent these crashes with the following changes: - Add a mutex to protect against two processes mmapping the same binder_proc. - After locking mmap_sem, check that the vma we want to access (still) points to the same mm_struct. - Use proc->tsk instead of current to get the files struct since this is where we get the rlimit from.
