Christopher Harvey 2f5c638ced staging: usbip: fix potential segfault because of unchecked return value of strchr.
This doesn't happen with the usbip virtual hci module, but another
module wanting to interface with this user space code could cause a
seg-fault by sending data without newlines.

Oleg Nesterov ba46ce30f1 staging: usbip: fix the usage of kthread_stop()
stub_shutdown_connection() and vhci_shutdown_connection() use
task_is_dead() before kthread_stop(). This buys nothing and wrong.
kthread_stop() is fine even if this thread is dead. However, if it
is dead nothing protects this task_struct, we shouldn't touch this
memory.

Change the code to do the necessary get_task_struct/put_task_struct.

This patch assumes that

	- xxx_shutdown_connection() is always called, so we can't
	  leak the task_struct.

	- kthread_stop_put() can't be called twice on the same task.

Bart Westgeest 737912e11b staging: usbip: fix to prevent potentially using uninitialized spinlock
The stub_probe function can be called as soon as the stub_driver is
registered. This can lead to the busid_table_lock being used before it
is initialized. Moved calling the init_busid_table function (which
initalizes this spinlock) to be called earlier in the init function to
prevent this from happening.

Tobias Klauser 8547d4cc2b Staging: usbip: vhci-hcd: Do not kill already dead RX/TX kthread
When unbinding a device on the host which was still attached on the
client, I got a NULL pointer dereference on the client. This turned out
to be due to kthread_stop() being called on an already dead kthread.

Here is how I was able to reproduce the problem:

 server:# usbip bind -b 1-2
                                client:# usbip attach -h server -b 1-2
 server:# usbip unbind -b 1-2

This patch fixes the problem by checking the kthread before attempting
to kill it, as it is done on the opposite side in
stub_shutdown_connection().

matt mooney 099f79fa5a staging: usbip: userspace: libsrc: remove usbip.h
