2020-06-20r8169: fix firmware not resetting tp->ocp_baseHeiner Kallweit1-1/+4
Typically the firmware takes care that tp->ocp_base is reset to its default value. That's not the case (at least) for RTL8117. As a result subsequent PHY access reads/writes the wrong page and the link is broken. Fix this be resetting tp->ocp_base explicitly.

2020-06-20ionic: tame the watchdog timer on reconfigShannon Nelson1-7/+8
Even with moving netif_tx_disable() to an earlier point when taking down the queues for a reconfiguration, we still end up with the occasional netdev watchdog Tx Timeout complaint. The old method of using netif_trans_update() works fine for queue 0, but has no effect on the remaining queues. Using netif_device_detach() allows us to signal to the watchdog to ignore us for the moment.

2020-06-19enetc: Fix HW_VLAN_CTAG_TX|RX togglingClaudiu Manoil3-16/+34
VLAN tag insertion/extraction offload is correctly activated at probe time but deactivation of this feature (i.e. via ethtool) is broken. Toggling works only for Tx/Rx ring 0 of a PF, and is ignored for the other rings, including the VF rings. To fix this, the existing VLAN offload toggling code was extended to all the rings assigned to a netdevice, instead of the default ring 0 (likely a leftover from the early validation days of this feature). And the code was moved to the common set_features() function to fix toggling for the VF driver too.

2020-06-18i40e: fix crash when Rx descriptor count is changedBjörn Töpel1-0/+3
When the AF_XDP buffer allocator was introduced, the Rx SW ring "rx_bi" allocation was moved from i40e_setup_rx_descriptors() function, and was instead done in the i40e_configure_rx_ring() function. This broke the ethtool set_ringparam() hook for changing the Rx descriptor count, which was relying on i40e_setup_rx_descriptors() to handle the allocation. Fix this by adding an explicit i40e_alloc_rx_bi() call to i40e_set_ringparam().

2020-06-16e1000: use generic power managementVaibhav Gupta1-36/+13
With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let PCI core handle the work. e1000_suspend() calls __e1000_shutdown() to perform intermediate tasks. __e1000_shutdown() modifies the value of "wake" (device should be wakeup enabled or not), responsible for controlling the flow of legacy PM. Since, PCI core has no idea about the value of "wake", new code for generic PM may produce unexpected results. Thus, use "device_set_wakeup_enable()" to wakeup-enable the device accordingly.

2020-06-15net: ethernet: mtk-star-emac: simplify interrupt handlingBartosz Golaszewski1-89/+29
During development we tried to make the interrupt handling as fine-grained as possible with TX and RX interrupts being disabled/enabled independently and the counter registers reset from workqueue context. Unfortunately after thorough testing of current mainline, we noticed the driver has become unstable under heavy load. While this is hard to reproduce, it's quite consistent in the driver's current form. This patch proposes to go back to the previous approach of doing all processing in napi context with all interrupts masked in order to make the driver usable in mainline linux. This doesn't impact the performance on pumpkin boards at all and it's in line with what many ethernet drivers do in mainline linux anyway. At the same time we're adding a FIXME comment about the need to improve the interrupt handling.

There is a race condition exist during termination. The path is alx_stop and then alx_remove. An alx_schedule_link_check could be called before alx_stop by interrupt handler and invoke alx_link_check later. Alx_stop frees the napis, and alx_remove cancels any pending works. If any of the work is scheduled before termination and invoked before alx_remove, a null-ptr-deref occurs because both expect alx->napis[i]. This patch fix the race condition by moving cancel_work_sync functions before alx_free_napis inside alx_stop.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2020-06-11 This series contains fixes to the iavf driver. Brett fixes the supported link speeds in the iavf driver, which was only able to report speeds that the i40e driver supported and was missing the speeds supported by the ice driver. In addition, fix how 2.5 and 5.0 GbE speeds are reported. Alek fixes a enum comparison that was comparing two different enums that may have different values, so update the comparison to use matching enums. Paul increases the time to complete a reset to allow for 128 VFs to complete a reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-11net/mlx5: E-Switch, Fix some error pointer dereferencesDan Carpenter1-2/+4
We can't leave "counter" set to an error pointer. Otherwise either it will lead to an error pointer dereference later in the function or it leads to an error pointer dereference when we call mlx5_fc_destroy().

Clang warns: drivers/net/ethernet/mellanox/mlx5/core/main.c:1278:6: warning: variable 'err' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] if (!priv->dbg_root) { ^~~~~~~~~~~~~~~ drivers/net/ethernet/mellanox/mlx5/core/main.c:1303:9: note: uninitialized use occurs here return err; ^~~ drivers/net/ethernet/mellanox/mlx5/core/main.c:1278:2: note: remove the 'if' if its condition is always false if (!priv->dbg_root) { ^~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/mellanox/mlx5/core/main.c:1259:9: note: initialize the variable 'err' to silence this warning int err; ^ = 0 1 warning generated. The check of returned value of debugfs_create_dir() is wrong because by the design debugfs failures should never fail the driver and the check itself was wrong too. The kernel compiled without CONFIG_DEBUG_FS will return ERR_PTR(-ENODEV) and not NULL as expected.

2020-06-11net/mlx5: Fix devlink objects and devlink device unregister sequenceParav Pandit1-14/+13
Current below problems exists. 1. devlink device is registered by mlx5_load_one(). But it is not unregistered by mlx5_unload_one(). This is incorrect. 2. Above issue leads to, When mlx5 PCI device is removed, currently devlink device is unregistered before devlink ports are unregistered in below ladder diagram. remove_one() mlx5_devlink_unregister() [..] devlink_unregister() <- ports are still registered! mlx5_unload_one() mlx5_unregister_device() mlx5_remove_device() mlx5e_remove() mlx5e_devlink_port_unregister() devlink_port_unregister() 3. Condition checking for registering and unregister device are not symmetric either in these routines. Hence, fix the sequence by having load and unload routines symmetric and in right order. i.e. (a) register devlink device followed by registering devlink ports (b) unregister devlink ports followed by devlink device Do this based on boot and cleanup flags instead of different conditions.

While unregistration is in progress, user might be reloading the interface. This can race with unregistration in below flow which uses the resources which are getting disabled by reload flow. Hence, disable the devlink reloading first when removing the device.
