Subject: [PATCH for-next 0/6] RDMA/rxe: Fix potential races
Date: Sun, 10 Oct 2021 18:59:25 -0500 [thread overview]
Message-ID: <20211010235931.24042-1-rpearsonhpe@gmail.com> (raw)
There are possible race conditions related to attempting to access
rxe pool objects at the same time as the pools or elements are being
freed. This series of patches addresses these races.
Bob Pearson (6):
RDMA/rxe: Make rxe_alloc() take pool lock
RDMA/rxe: Copy setup parameters into rxe_pool
RDMA/rxe: Save object pointer in pool element
RDMA/rxe: Combine rxe_add_index with rxe_alloc
RDMA/rxe: Combine rxe_add_key with rxe_alloc
RDMA/rxe: Fix potential race condition in rxe_pool
