The current implementation of rxe_check_bind_mw() in rxe_mw.c is incorrect since it requires the new key portion provided by the mw consumer to be different than the previous key portion.

2022-07-19RDMA/mlx5: Expose steering anchor to userspaceMark Bloch
Expose a steering anchor per priority to allow users to re-inject packets back into default NIC pipeline for additional processing. MLX5_IB_METHOD_STEERING_ANCHOR_CREATE returns a flow table ID which a user can use to re-inject packets at a specific priority. A FTE (flow table entry) can be created and the flow table ID used as a destination. When a packet is taken into a RDMA-controlled steering domain (like software steering) there may be a need to insert the packet back into the default NIC pipeline. This exposes a flow table ID to the user that can be used as a destination in a flow table entry. With this new method priorities that are exposed to users via MLX5_IB_METHOD_FLOW_MATCHER_CREATE can be reached from a non-zero UID. As user-created flow tables (via RDMA DEVX) are created with a non-zero UID thus it's impossible to point to a NIC core flow table (core driver flow tables are created with UID value of zero) from userspace. Create flow tables that are exposed to users with the shared UID, this allows users to point to default NIC flow tables. Steering loops are prevented at FW level as FW enforces that no flow table at level X can point to a table at level lower than X.

2022-07-18RDMA/rxe: Fix BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanupZhu Yanjun
The function rxe_create_qp calls rxe_qp_from_init. If some error occurs, the error handler of function rxe_qp_from_init will set both scq and rcq to NULL. Then rxe_create_qp calls rxe_put to handle qp. In the end, rxe_qp_do_cleanup is called by rxe_put. rxe_qp_do_cleanup directly accesses scq and rcq before checking them. This will cause null-ptr-deref error. The call graph is as below: rxe_create_qp { ... rxe_qp_from_init { ... err1: ... qp->rcq = NULL; <---rcq is set to NULL qp->scq = NULL; <---scq is set to NULL ... } qp_init: rxe_put{ ... rxe_qp_do_cleanup { ... atomic_dec(&qp->scq->num_wq); <--- scq is accessed ... atomic_dec(&qp->rcq->num_wq); <--- rcq is accessed } } Fixes: 4703b4f0d94a ("RDMA/rxe: Enforce IBA C11-17") Link: https://lore.kernel.org/r/20220705225414.315478-1-yanjun.zhu@linux.dev Signed-off-by: Zhu Yanjun <yanjun.zhu@linux.dev> Reviewed-by: Bob Pearson <rpearsonhpe@gmail.com> Reviewed-by: Md Haris Iqbal <haris.iqbal@ionos.com> Signed-off-by: Leon Romanovsky <leon@kernel.org>
