net: ethernet: mtk_ppe: fix possible NULL pointer dereference in mtk_flow_get_wdma_info

2022-07-20T00:27:18+00:00

odev pointer can be NULL in mtk_flow_offload_replace routine according to the flower action rules. Fix possible NULL pointer dereference in mtk_flow_get_wdma_info.

net: ethernet: mtk_eth_soc: fix off by one check of ARRAY_SIZE

2022-07-19T03:12:04+00:00

In mtk_wed_tx_ring_setup(.., int idx, ..), idx is used as an index here struct mtk_wed_ring *ring = &dev->tx_ring[idx]; The bounds of idx are checked here BUG_ON(idx > ARRAY_SIZE(dev->tx_ring)); If idx is the size of the array, it will pass this check and overflow. So change the check to >= .

net: ethernet: mtk_eth_soc: fix misuse of mem alloc interface netdev[napi]_alloc_frag

2022-06-09T03:37:27+00:00

When rx_flag == MTK_RX_FLAGS_HWLRO, rx_data_len = MTK_MAX_LRO_RX_LENGTH(4096 * 3) > PAGE_SIZE. netdev_alloc_frag is for alloction of page fragment only. Reference to other drivers and Documentation/vm/page_frags.rst Branch to use __get_free_pages when ring->frag_size > PAGE_SIZE.

net: ethernet: mtk_eth_soc: out of bounds read in mtk_hwlro_get_fdir_entry()

2022-05-27T06:59:41+00:00

The "fsp->location" variable comes from user via ethtool_get_rxnfc(). Check that it is valid to prevent an out of bounds read. Fixes: 7aab747e5563 ("net: ethernet: mediatek: add ethtool functions to configure RX flows of HW LRO") Signed-off-by: Dan Carpenter Signed-off-by: David S. Miller
