Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
RDMA/rxe: Fix error unwind in rxe_create_qp()<br />
<br />
In the function rxe_create_qp(), rxe_qp_from_init() is called to<br />
initialize qp, internally things like the spin locks are not setup until<br />
rxe_qp_init_req().<br />
<br />
If an error occures before this point then the unwind will call<br />
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()<br />
which will oops when trying to access the uninitialized spinlock.<br />
<br />
Move the spinlock initializations earlier before any failures.
