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

2022-06-25T09:45:17Z

[ Upstream commit 2f2c0d2919a14002760f89f4e02960c735a316d2 ] 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()

2022-06-14T14:52:38Z

[ Upstream commit e7e7104e2d5ddf3806a28695670f21bef471f1e1 ] The "fsp->location" variable comes from user via ethtool_get_rxnfc(). Check that it is valid to prevent an out of bounds read.

net: ethernet: mtk_eth_soc: fix RX VLAN offload

2021-05-22T08:40:30Z

[ Upstream commit 3f57d8c40fea9b20543cab4da12f4680d2ef182c ] The VLAN ID in the rx descriptor is only valid if the RX_DMA_VTAG bit is set. Fixes frames wrongly marked with VLAN tags.

net: ethernet: mediatek: Use NET_IP_ALIGN to judge if HW RX_2BYTE_OFFSET is enabled

2019-07-10T07:55:30Z

[ Upstream commit 880c2d4b2fdfd580ebcd6bb7240a8027a1d34751 ] Should only enable HW RX_2BYTE_OFFSET function in the case NET_IP_ALIGN equals to 2. Signed-off-by: Mark Lee Signed-off-by: Sean Wang Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

net: ethernet: mediatek: Use hw_feature to judge if HWLRO is supported

[ Upstream commit 9e4f56f1a7f3287718d0083b5cb85298dc05a5fd ] Should hw_feature as hardware capability flags to check if hardware LRO got support. Signed-off-by: Mark Lee Signed-off-by: Sean Wang Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

net: mediatek: setup proper state for disabled GMAC on the default

2018-03-03T09:23:22Z

[ Upstream commit 7352e252b5bf40d59342494a70354a2d436fd0cd ] The current solution would setup fixed and force link of 1Gbps to the both GMAC on the default. However, The GMAC should always be put to link down state when the GMAC is disabled on certain target boards. Otherwise, the driver possibly receives unexpected data from the floating hardware connection through the unused GMAC. Although the driver had been added certain protection in RX path to get rid of such kind of unexpected data sent to the upper stack. Signed-off-by: Sean Wang Signed-off-by: David S.

net-next: ethernet: mediatek: change the compatible string

2017-06-17T04:41:55Z

[ Upstream commit 8b901f6bbcf12a20e43105d161bedde093431e61 ] When the binding was defined, I was not aware that mt2701 was an earlier version of the SoC. For sake of consistency, the ethernet driver should use mt2701 inside the compat string as this is the earliest SoC with the ethernet core. The ethernet driver is currently of no real use until we finish and upstream the DSA driver. There are no users of this binding yet. It should be safe to fix this now before it is too late and we need to provide backward compatibility for the mt7623-eth compat string.

net: ethernet: mediatek: fix fixed-link phydev leaks

net: ethernet: mediatek: get hw lro capability by the chip id instead of by the dtsi

2016-10-07T01:08:08Z

Because hw lro started to be supported from MT7623, the proper way to check if the feature is capable is to judge by the chip id instead of by the dtsi. Signed-off-by: Nelson Chang Signed-off-by: David S. Miller
