2019-12-07net: phy: dp83867: fix hfs boot in rgmii modeGrygorii Strashko1-48/+71
The commit ef87f7da6b28 ("net: phy: dp83867: move dt parsing to probe") causes regression on TI dra71x-evm and dra72x-evm, where DP83867 PHY is used in "rgmii-id" mode - the networking stops working. Unfortunately, it's not enough to just move DT parsing code to .probe() as it depends on phydev->interface value, which is set to correct value abter the .probe() is completed and before calling .config_init(). So, RGMII configuration can't be loaded from DT. To fix and issue - move RGMII validation code to .config_init() - parse RGMII parameters in dp83867_of_init(), but consider them as optional.

2019-12-06lpc_eth: kernel BUG on removeBruno Carneiro da Cunha1-2/+0
We may have found a bug in the nxp/lpc_eth.c driver. The function platform_set_drvdata() is called twice, the second time it is called, in lpc_mii_init(), it overwrites the struct net_device which should be at pdev->dev->driver_data with pldat->mii_bus. When trying to remove the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will return the pldat->mii_bus pointer and try to use it as a struct net_device pointer. This causes unregister_netdev to segfault and generate a kernel BUG. Is this reproducible?

The EEE support has not been enabled on ENETC, but it may connect to a PHY which supports EEE and advertises EEE by default, while its link partner also advertises EEE. If this happens, the PHY enters low power mode when the traffic rate is low and causes packet loss. This patch disables EEE advertisement by default for any PHY that ENETC connects to, to prevent the above unwanted outcome.

Currently, hns3_nic_maybe_stop_tx() uses skb_copy() to linearize a SKB if the BD num required by the SKB does not meet the hardware limitation, and it linearizes the SKB by allocating a new linearized SKB and freeing the old SKB, if hns3_nic_maybe_stop_tx() returns -EBUSY because there are no enough space in the ring to send the linearized skb to hardware, the sch_direct_xmit() still hold reference to old SKB and try to retransmit the old SKB when dev_hard_start_xmit() return TX_BUSY, which may cause use after freed problem.

This patch fixes it by rechecking the ring_space after netif_stop_subqueue to make sure TX queue is restarted. Also, the ring->next_to_clean is updated even when pkts is zero, because all the TX BD cleaned may be non-SKB, so it needs to check if TX queue need to be restarted.

2019-12-05net/mlx5e: Fix TXQ indices to be sequentialEran Ben Elisha4-22/+15
Cited patch changed (channel index, tc) => (TXQ index) mapping to be a static one, in order to keep indices consistent when changing number of channels or TCs. For 32 channels (OOB) and 8 TCs, real num of TXQs is 256. When reducing the amount of channels to 8, the real num of TXQs will be changed to 64. This indices method is buggy: - Channel #0, TC 3, the TXQ index is 96. - Index 8 is not valid, as there is no such TXQ from driver perspective (As it represents channel #8, TC 0, which is not valid with the above configuration). As part of driver's select queue, it calls netdev_pick_tx which returns an index in the range of real number of TXQs. Depends on the return value, with the examples above, driver could have returned index larger than the real number of tx queues, or crash the kernel as it tries to read invalid address of SQ which was not allocated. Fix that by allocating sequential TXQ indices, and hold a new mapping between (channel index, tc) => (real TXQ index). This mapping will be updated as part of priv channels activation, and is used in mlx5e_select_queue to find the selected queue index. The existing indices mapping (channel_tc2txq) is no longer needed, as it is used only for statistics structures and can be calculated on run time. Delete its definintion and updates.

ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route().

2019-12-01net: phy: realtek: fix using paged operations with RTL8105e / RTL8208Heiner Kallweit1-0/+9
It was reported [0] that since the referenced commit a warning is triggered in phylib that complains about paged operations being used with a PHY driver that doesn't support this. The commit isn't wrong, just for one chip version (RTL8105e) no dedicated PHY driver exists yet. So add the missing PHY driver.

2019-12-01r8169: fix resume on cable plug-inHeiner Kallweit1-0/+1
It was reported [0] that network doesn't wake up on cable plug-in with certain chip versions. Reason is that on these chip versions the PHY doesn't detect cable plug-in when being in power-down mode. So prevent the PHY from powering down if WoL is enabled.

Alan reported [0] that network is broken since the referenced commit when using jumbo frames. This commit isn't wrong, it just revealed another issue that has been existing before. According to the vendor driver the RTL8168e-specific jumbo config doesn't apply for RTL8168evl.
