net: mana: Add rmb after checking owner bits

2022-09-28T09:32:07Z

commit 6fd2c68da55c552f86e401ebe40c4a619025ef69 upstream. Per GDMA spec, rmb is necessary after checking owner_bits, before reading EQ or CQ entries. Add rmb in these two places to comply with the specs.

net: mana: Remove unnecessary check of cqe_type in mana_process_rx_cqe()

2022-02-05T15:26:00Z

The switch statement already ensures cqe_type == CQE_RX_OKAY at that point. Signed-off-by: Haiyang Zhang Reviewed-by: Dexuan Cui Signed-off-by: David S. Miller

net: mana: Add handling of CQE_RX_TRUNCATED

2022-02-05T15:26:00Z

The proper way to drop this kind of CQE is advancing rxq tail without indicating the packet to the upper network layer. Signed-off-by: Haiyang Zhang Reviewed-by: Dexuan Cui Signed-off-by: David S. Miller

net: mana: Use struct_size() helper in mana_gd_create_dma_region()

2022-01-25T12:59:18Z

Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows. Also, address the following sparse warnings: drivers/net/ethernet/microsoft/mana/gdma_main.c:677:24: warning: using sizeof on a flexible structure Link: https://github.com/KSPP/linux/issues/174 Signed-off-by: Gustavo A.
