2018-10-29mlxsw: core: Fix devlink unregister flowShalom Toledo1-7/+17
After a failed reload, the driver is still registered to devlink, its devlink instance is still allocated and the 'reload_fail' flag is set. Then, in the next reload try, the driver's allocated devlink instance will be freed without unregistering from devlink and its components (e.g, resources). This scenario can cause a use-after-free if the user tries to execute command via devlink user-space tool. Fix by not freeing the devlink instance during reload (failed or not).

2018-10-25r8169: fix broken Wake-on-LAN from S5 (poweroff)Heiner Kallweit1-2/+7
It was reported that WoL from S5 is broken (WoL from S3 works) and the analysis showed that during system shutdown the network interface was brought down already when the actual kernel shutdown started. Therefore netif_running() returned false and as a consequence the PHY was suspended. Obviously WoL wasn't working then. To fix this the original patch needs to be effectively reverted. A side effect is that when normally bringing down the interface and WoL is enabled the PHY will remain powered on (like it was before the original patch).

Jeff Kirsher says: ==================== Intel Wired LAN Driver Fixes 2018-10-24 This series contains fixes for the ice driver. Anirudh fixes a namespace issue which was introduced with a previous patch to remove ice_netpoll. Fixed up the device ID define names to align with the branding string names. Use the capability count returned by the firmware, instead of calculating the count. Introduced driver workarounds due to current firmware limitations. Fixed the queue mapping for a VF, which needs to be set in the config and scatter queue modes. Fixed the driver which is setup to handle link status events (LSE), even though the firmware does not have this feature yet, so add the ability to poll for link status changes while we wait for updated firmware. ==================== Signed-off-by: David S.

2018-10-24ice: Poll for link status changeAnirudh Venkataramanan3-120/+25
When the physical link goes up or down, the driver is supposed to receive a link status event (LSE). The driver currently has the code to handle LSEs but there is no firmware support for this feature yet. So this patch adds the ability for the driver to poll for link status changes. The polling itself is done in ice_watchdog_subtask. For namespace cleanliness, this patch also removes code that handles LSE. This code will be reintroduced once the feature is officially supported.

Use the new of_get_compatible_child() helper to lookup the mdio-internal child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the mdio-mux node). Fortunately, this was inadvertently balanced by a failure to drop the mdio-mux reference after lookup. While at it, also fix the related mdio-internal- and phy-node reference leaks.

2018-10-23net: socionext: Add dummy PHY register read in phy_write()Masahisa Kojima1-2/+16
There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E.

2018-10-23net: socionext: Stop PHY before resetting netsecMasahisa Kojima1-4/+15
In ndo_stop, driver resets the netsec ethernet controller IP. When the netsec IP is reset, HW running mode turns to NRM mode and driver has to wait until this mode transition completes. But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.

This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured.
