RDMA/netdev: Fix netlink support in IPoIB

2018-10-11T00:58:12Z

IPoIB netlink support was broken by the below commit since integrating the rdma_netdev support relies on an allocation flow for netdevs that was controlled by the ipoib driver while netdev's rtnl_newlink implementation assumes that the netdev will be allocated by netlink. Such situation leads to crash in __ipoib_device_add, once trying to reuse netlink device. This patch fixes the kernel oops for both mlx4 and mlx5 devices triggered by the following command: Fixes: cd565b4b51e5 ("IB/IPoIB: Support acceleration options callbacks") Signed-off-by: Denis Drozdov Signed-off-by: Jason Gunthorpe Signed-off-by: Feras Daoud Signed-off-by: Saeed Mahameed

RDMA/netdev: Hoist alloc_netdev_mqs out of the driver

2018-10-11T00:58:11Z

netdev has several interfaces that expect to call alloc_netdev_mqs from the core code, with the driver only providing the arguments. This is incompatible with the rdma_netdev interface that returns the netdev directly. Thus re-organize the API used by ipoib so that the verbs core code calls alloc_netdev_mqs for the driver. This is done by allowing the drivers to provide the allocation parameters via a 'get_params' callback and then initializing an allocated netdev as a second step.

RDMA/core: Use dev_err/dbg/etc instead of pr_* + ibdev->name

2018-09-26T19:51:48Z

Any messages related to a device should be printed with the dev_* formatters. This provides greater consistency for the user. The core does not set pr_fmt so this has no significant change.
