2019-01-28usb: dwc3: exynos: Fix error handling of clk_prepare_enableAlexey Khoroshilov
If clk_prepare_enable() fails in dwc3_exynos_probe() or in dwc3_exynos_resume(), exynos->clks[0] is left undisabled because of usage preincrement in while condition. Found by Linux Driver Verification project (linuxtesting.org).

2019-01-25net/mlx5e: Unblock setting vid 0 for VFs through the uplink repOr Gerlitz

2019-01-25net/mlx5e: Move to use common phys port names for vport representorsOr Gerlitz
With VF LAG commit 491c37e49b48 "net/mlx5e: In case of LAG, one switch parent id is used for all representors", both uplinks and all the VFs (on both of them) get the same switchdev id. This cause the provisioning system method to identify the rep of a given VF from the parent PF PCI device using switchev id and physical port name to break, since VFm of PF0 will have the (id, name) as VFm of PF1. To fix that, we align to use the framework agreed upstream and set by nfp commit 168c478e107e "nfp: wire get_phys_port_name on representors": $ cat /sys/class/net/eth4_*/phys_port_name p0 pf0vf0 pf0vf1 Now, the names will be different, e.g. pf0vf0 vs. pf1vf0.

2019-01-25Revert "net/mlx5e: E-Switch, Initialize eswitch only if eswitch manager"Bodong Wang
This reverts commit 5f5991f36dce1e69dd8bd7495763eec2e28f08e7. With the original commit, eswitch instance will not be initialized for a function which is vport group manager but not eswitch manager such as host PF on SmartNIC (BlueField) card. This will result in a kernel crash when such a vport group manager is trying to access vports in its group. E.g, PF vport manager (not eswitch manager) tries to configure the MAC of its VF vport, a kernel trace will happen similar as bellow: BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 ...

2019-01-25RDMA/mlx5: Fix flow creation on representorsMark Bloch
The intention of the flow_is_supported was to disable the entire tree and methods that allow raw flow creation, but the grammar syntax has this disable the entire UVERBS_FLOW object. Since the method requires a MLX5_IB_OBJECT_FLOW_MATCHER there is no need to do anything, as it is automatically disabled when matchers are disabled. This restores the ability to create flow steering rules on representors via regular verbs.

2019-01-25IB/uverbs: Fix OOPs upon device disassociationYishai Hadas
The async_file might be freed before the disassociation has been ended, causing qp shutdown to use after free on it. Since uverbs_destroy_ufile_hw is not a fence, it returns if a disassociation is ongoing in another thread. It has to be written this way to avoid deadlock. However this means that the ufile FD close cannot destroy anything that may still be used by an active kref, such as the the async_file. To fix that move the kref_put() to be in ib_uverbs_release_file().
