CVE-2022-50127
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix error unwind in rxe_create_qp()
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like the spin locks are not setup until
rxe_qp_init_req().
If an error occures before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.
Move the spinlock initializations earlier before any failures.
