2019-07-01net/mlx5: E-Switch, Reg/unreg function changed event at correct stageBodong Wang
When driver is doing eswitch mode change, it's critical to keep number of enabled VFs unchanged. However, it can be changed on the fly once function changed event is registered. To remove this uncertainty, function changed event should not be registered before all setups, and first be unregistered before all cleanups. Wrap this functionality together with vport event handler.

2019-07-01net/mlx5: E-Switch, Consolidate eswitch function number of VFsBodong Wang
Enabled number of VFs is key for eswich manager to do flow steering initialization and vport configurations. However, the number of enabled VFs may come from two sources as below. PF: num of VFs is provided by enabled SR-IOV of itself. ECPF: num of VFs is provided by enabled SR-IOV from its peer PF. And SR-IOV can't be enabled from ECPF itself. Current driver handles the two cases in different stages and passing the number of enabled VFs among a large scope of internal functions. It is usually hard to find out where is the real number of VFs from due to layers of argument pass-in. This patch consolidated that number from the entry point of doing eswitch setup, and maintained a copy so that eswitch functions can refer to it directly. Eswitch driver shall always use this number when referring to enabled number of VFs, don't use other numbers such as from SR-IOV.

2019-07-01net/mlx5: E-Switch, Refactor eswitch SR-IOV interfaceBodong Wang
Devlink eswitch mode is not necessarily related to SR-IOV, e.g, ECPF can be at offload mode when SR-IOV is not enabled. Rename the interface and eswitch mode names to decouple from SR-IOV, and cleanup eswitch messages accordingly.

2019-07-01net/mlx5: Handle host PF vport mac/guid for ECPFBodong Wang
When ECPF is eswitch manager, it has the privilege to query and configure the mac and node guid of host PF. While vport number of host PF is 0, the vport command should be issued with other_vport set in this case as the cmd is issued by ECPF vport(0xfffe). Add a specific function to query own vport mac. Low level functions are used by vport manager to query/modify any vport mac and node guid. Signed-off-by: Bodong Wang <bodong@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2019-07-01net/mlx5: Reduce dependency on enabled_vfs counter and num_vfsParav Pandit
While enabling SR-IOV, PCI core already checks that if SR-IOV is already enabled, it returns failure error code. Hence, remove such duplicate check from mlx5_core driver. While at it, make mlx5_device_disable_sriov() to perform cleanup of VFs in reverse order of mlx5_device_enable_sriov().

2019-07-01net/mlx5: Don't handle VF func change if host PF is disabledBodong Wang
When ECPF eswitch manager is at offloads mode, it monitors functions changed event from host PF side and acts according to the number of VFs enabled/disabled. As ECPF and host PF work in two independent hosts, it's possible that host PF OS reboots but ECPF system is still kept on and continues monitoring events from host PF. When kernel from host PF side is booting, PCI iov driver does sriov_init and compute_max_vf_buses by iterating over all valid num of VFs. This triggers FLR and generates functions changed events, even though host PF HCA is not enabled at this time. However, ECPF is not aware of this information, and still handles these events as usual. ECPF system will see massive number of reps are created, but destroyed immediately once creation finished. To eliminate this noise, a bit is added to host parameter context to indicate host PF is disabled. ECPF will not handle the VF changed event if this bit is set.

Given a fw component index, the MCQS register allows us to query the status of a fw component, including its type and state (e.g. PRESET/IN_USE). It can be used to find the index of a component of a specific type, by sequentially increasing the component index, and querying each time the type of the returned component.

2019-07-01ALSA: hda: Fix widget_mutex incomplete protectionEvan Green
The widget_mutex was introduced to serialize callers to hda_widget_sysfs_{re}init. However, its protection of the sysfs widget array is incomplete. For example, it is acquired around the call to hda_widget_sysfs_reinit(), which actually creates the new array, but isn't still acquired when codec->num_nodes and codec->start_nid is updated. So the lock ensures one thread sets up the new array at a time, but doesn't ensure which thread's value will end up in codec->num_nodes. If a larger num_nodes wins but a smaller array was set up, the next call to refresh_widgets() will touch free memory as it iterates over codec->num_nodes that aren't there. The widget_lock really protects both the tree as well as codec->num_nodes, start_nid, and end_nid, so make sure it's held across that update. It should also be held during snd_hdac_get_sub_nodes(), so that a very old read from that function doesn't end up clobbering a later update.
