2017-09-01mlxsw: spectrum: Forbid linking to devices that have uppersIdo Schimmel1-0/+6
The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.

2017-08-31Input: xpad - fix PowerA init quirk for some gamepad modelsCameron Gutman1-5/+19
The PowerA gamepad initialization quirk worked with the PowerA wired gamepad I had around (0x24c6:0x543a), but a user reported [0] that it didn't work for him, even though our gamepads shared the same vendor and product IDs. When I initially implemented the PowerA quirk, I wanted to avoid actually triggering the rumble action during init. My tests showed that my gamepad would work correctly even if it received a rumble of 0 intensity, so that's what I went with. Unfortunately, this apparently isn't true for all models (perhaps a firmware difference?). This non-working gamepad seems to require the real magic rumble packet that the Microsoft driver sends, which actually vibrates the gamepad. To counteract this effect, I still send the old zero-rumble PowerA quirk packet which cancels the rumble effect before the motors can spin up enough to vibrate.

When changing from switchdev to legacy mode, all the representor port devices (uplink nic and reps) are cleaned up. Part of this cleaning process is removing the neigh entries and the hash table containing them. However, a representor neigh entry might be linked to the uplink port hash table and if the uplink nic is cleaned first the cleaning of the representor will end up in null deref. Fix that by unloading the representors in the opposite order of load.

Currently if vxlan tunnel ipv6 src isn't supplied the driver fails to resolve it as part of the route lookup. The resulting encap header is left with a zeroed out ipv6 src address so the packets are sent with this src ip.

2017-08-30net/mlx5: Skip mlx5_unload_one if mlx5_load_one failsHuy Nguyen1-3/+1
There is an issue where the firmware fails during mlx5_load_one, the health_care timer detects the issue and schedules a health_care call. Then the mlx5_load_one detects the issue, cleans up and quits. Then the health_care starts and calls mlx5_unload_one to clean up the resources that no longer exist and causes kernel panic. The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set after mlx5_load_one fails. The solution is removing the bit MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN is redundant and we can use MLX5_INTERFACE_STATE_UP instead.

2017-08-30nvme-pci: use dma memory for the host memory buffer descriptorsChristoph Hellwig1-11/+11
The NVMe 1.3 specification says in section 5.21.1.13: "After a successful completion of a Set Features enabling the host memory buffer, the host shall not write to the associated host memory region, buffer size, or descriptor list until the host memory buffer has been disabled." While this doesn't state that the descriptor list must remain accessible to the device it certainly implies it must remaing readable by the device. So switch to a dma coherent allocation for the descriptor list just to be safe - it's not like the cost for it matters compared to the actual memory buffers.
