2022-09-27s390/qeth: Split memcpy() of struct qeth_ipacmd_addr_change flexible arrayKees Cook
To work around a misbehavior of the compiler's ability to see into composite flexible array structs (as detailed in the coming memcpy() hardening series[1]), split the memcpy() of the header and the payload so no false positive run-time overflow warning will be generated.

2022-09-27vdpa/mlx5: Fix MQ to support non power of two num queuesEli Cohen
RQT objects require that a power of two value be configured for both rqt_max_size and rqt_actual size. For create_rqt, make sure to round up to the power of two the value of given by the user who created the vdpa device and given by ndev->rqt_size. The actual size is also rounded up to the power of two using the current number of VQs given by ndev->cur_num_vqs. Same goes with modify_rqt where we need to make sure act size is power of two based on the new number of QPs. Without this patch, attempt to create a device with non power of two QPs would result in error from firmware.

2022-09-27i2c: mlxbf: support BlueField-3 SoCAsmaa Mnebhi
BlueField-3 SoC has the same I2C IP logic as previous BlueField-1 and 2 SoCs but it has different registers' addresses. This is an effort to keep this driver generic across all BlueField generations. This patch breaks down the "smbus" resource into 3 separate resources to enable us to use common registers' offsets for all BlueField SoCs: struct mlxbf_i2c_resource *timer; struct mlxbf_i2c_resource *mst; struct mlxbf_i2c_resource *slv; Of course, all offsets had to be adjusted accordingly, and we took this chance to reorganize the macros depending on the register block they target. There are only 2 registers' offsets that do not fit within this schema so their offsets are passed as SoC-specific parameters: smbus_master_rs_bytes_off smbus_master_fsm_off Reviewed-by: Khalil Blaiech <kblaiech@nvidia.com> Signed-off-by: Asmaa Mnebhi <asmaa@nvidia.com> Signed-off-by: Wolfram Sang <wsa@kernel.org>

2022-09-27RDMA/mlx5: Don't set tx affinity when lag is in hash modeLiu, Changcheng
In hash mode, without setting tx affinity explicitly, the port select flow table decides which port is used for the traffic. If port_select_flow_table_bypass capability is supported and tx affinity is set explicitly for QP/TIS, they will be added into the explicit affinity table in FW to check which port is used for the traffic. 1. The overloaded explicit affinity table may affect performance. To avoid this, do not set tx affinity explicitly by default. 2. The packets of the same flow need to be transmitted on the same port. Because the packets of the same flow use different QPs in slow & fast path, it shouldn't set tx affinity explicitly for these QPs.
