2022-11-23net: ethernet: mtk_eth_soc: fix memory leak in error pathYan Cangang3-6/+23
In mtk_ppe_init(), when dmam_alloc_coherent() or devm_kzalloc() failed, the rhashtable ppe->l2_flows isn't destroyed. Fix it.

2022-11-23net: ethernet: mtk_eth_soc: fix potential memory leak in mtk_rx_alloc()Ziyang Xuan1-1/+3
When fail to dma_map_single() in mtk_rx_alloc(), it returns directly. But the memory allocated for local variable data is not freed, and local variabel data has not been attached to ring->data[i] yet, so the memory allocated for local variable data will not be freed outside mtk_rx_alloc() too. Thus memory leak would occur in this scenario. Add skb_free_frag(data) when dma_map_single() failed.

2022-09-27net: ethernet: mtk_eth_soc: fix usage of foe_entry_sizeDaniel Golle1-1/+1
As sizeof(hwe->data) can now longer be used as the actual size depends on foe_entry_size, in commit 9d8cb4c096ab02 ("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the use of sizeof(hwe->data) is hence replaced. However, replacing it with ppe->eth->soc->foe_entry_size is wrong as foe_entry_size represents the size of the whole descriptor and not just the 'data' field. Fix this by subtracing the size of the only other field in the struct 'ib1', so we actually end up with the correct size to be copied to the data field.

2022-09-20net: dsa: introduce dsa_port_get_master()Vladimir Oltean1-1/+1
There is a desire to support for DSA masters in a LAG. That configuration is intended to work by simply enslaving the master to a bonding/team device. But the physical DSA master (the LAG slave) still has a dev->dsa_ptr, and that cpu_dp still corresponds to the physical CPU port. However, we would like to be able to retrieve the LAG that's the upper of the physical DSA master. In preparation for that, introduce a helper called dsa_port_get_master() that replaces all occurrences of the dp->cpu_dp->master pattern. The distinction between LAG and non-LAG will be made later within the helper itself.

mtk_xdp_submit_frame Get rid of unnecessary txd_pdma pointer in mtk_xdp_submit_frame for loop since it is actually used at the end of the routine using latest mtk_tx_dma consumed pointer as reference.

2022-07-25net: ethernet: mtk-ppe: fix traffic offload with bridged wlanLorenzo Bianconi1-17/+13
A typical flow offload scenario for OpenWrt users is routed traffic received by the wan interface that is redirected to a wlan device belonging to the lan bridge. Current implementation fails to fill wdma offload info in mtk_flow_get_wdma_info() since odev device is the local bridge. Fix the issue running dev_fill_forward_path routine in mtk_flow_get_wdma_info in order to identify the wlan device.
