Pull rdma updates from Jason Gunthorpe: "This has been a fairly typical cycle, with the usual sorts of driver updates. Several series continue to come through which improve and modernize various parts of the core code, and we finally are starting to get the uAPI command interface cleaned up. - Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4, mlx5, qib, rxe, usnic - Rework the entire syscall flow for uverbs to be able to run over ioctl(). Finally getting past the historic bad choice to use write() for command execution - More functional coverage with the mlx5 'devx' user API - Start of the HFI1 series for 'TID RDMA' - SRQ support in the hns driver - Support for new IBTA defined 2x lane widths - A big series to consolidate all the driver function pointers into a big struct and have drivers provide a 'static const' version of the struct instead of open coding initialization - New 'advise_mr' uAPI to control device caching/loading of page tables - Support for inline data in SRPT - Modernize how umad uses the driver core and creates cdev's and sysfs files - First steps toward removing 'uobject' from the view of the drivers" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (193 commits) RDMA/srpt: Use kmem_cache_free() instead of kfree() RDMA/mlx5: Signedness bug in UVERBS_HANDLER() IB/uverbs: Signedness bug in UVERBS_HANDLER() IB/mlx5: Allocate the per-port Q counter shared when DEVX is supported IB/umad: Start using dev_groups of class IB/umad: Use class_groups and let core create class file IB/umad: Refactor code to use cdev_device_add() IB/umad: Avoid destroying device while it is accessed IB/umad: Simplify and avoid dynamic allocation of class IB/mlx5: Fix wrong error unwind IB/mlx4: Remove set but not used variable 'pd' RDMA/iwcm: Don't copy past the end of dev_name() string IB/mlx5: Fix long EEH recover time with NVMe offloads IB/mlx5: Simplify netdev unbinding IB/core: Move query port to ioctl RDMA/nldev: Expose port_cap_flags2 IB/core: uverbs copy to struct or zero helper IB/rxe: Reuse code which sets port state IB/rxe: Make counters thread safe IB/mlx5: Use the correct commands for UMEM and UCTX allocation ...

2018-12-21IB/mlx5: Allocate the per-port Q counter shared when DEVX is supportedYishai Hadas3-2/+26
The per-port Q counter is some kernel resource and as such may be used by few UID(s) upon DEVX usage. To enable using it for QP/RQ when DEVX context is used need to allocate it with a sharing mode indication to let firmware allows its usage. The UID = 0xffff was chosen to mark it.

2018-12-20IB/mlx5: Use the correct commands for UMEM and UCTX allocationYishai Hadas1-19/+15
During testing the command format was changed to close a security hole. Revise the driver to use the command format that will actually be supported in GA firmware. Both the UMEM and UCTX are intended only for use by the kernel and cannot be executed using a general command. Since the UMEM and CTX are not part of the general object the caps bits were moved to be some log_xxx location in the general HCA caps. The firmware code was adapted as well to match the above.

2018-12-20IB/usnic: Fix potential deadlockParvi Kaustubhi1-4/+7
Acquiring the rtnl lock while holding usdev_lock could result in a deadlock. For example: usnic_ib_query_port() | mutex_lock(&us_ibdev->usdev_lock) | ib_get_eth_speed() | rtnl_lock() rtnl_lock() | usnic_ib_netdevice_event() | mutex_lock(&us_ibdev->usdev_lock) This commit moves the usdev_lock acquisition after the rtnl lock has been released. This is safe to do because usdev_lock is not protecting anything being accessed in ib_get_eth_speed(). Hence, the correct order of holding locks (rtnl -> usdev_lock) is not violated.

With this change all the IB devices in switchdev mode are created only once the load callback is invoked by the e-switch core sub-module.
