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.
