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