2023-06-10net/mlx5: Set max number of embedded CPU VFsDaniel Jurgens1-0/+1
Set the maximum number of embedded cpu VF functions available. Signed-off-by: Daniel Jurgens <danielj@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2023-06-10net/mlx5: Update SRIOV enable/disable to handle EC/VFsDaniel Jurgens3-9/+30
Previously on the embedded CPU platform SRIOV was never enabled/disabled via mlx5_core_sriov_configure. Host VF updates are provided by an event handler. Now in the disable flow it must be known if this is a disable due to driver unload or SRIOV detach, or if the user updated the number of VFs. If due to change in the number of VFs only wait for the pages of ECVFs.

2023-06-10net/mlx5: Query correct caps for min msix vectorsDaniel Jurgens1-1/+15

2023-06-10net/mlx5: Use correct vport when restoring GUIDsDaniel Jurgens1-3/+7
Prior to enabling EC VF functionality the vport number and function ID were always the same. That's not the case now. Use the correct vport number to modify the HCA vport context.

2023-06-10net/mlx5: Add new page type for EC VF pagesDaniel Jurgens3-1/+12
When the embedded cpu supports SRIOV it can be enabled and disabled independently from the host SRIOV. Track the pages separately so we can properly wait for returned VF pages.

Add and remove the peer miss rules for EC VFs. It's possible that there are different amounts of total VFs per function so only create rules for the minimum number of max VFs.

2023-06-10net/mlx5: Add management of EC VF vportsDaniel Jurgens3-17/+143
Add init, load, unload, and cleanup of the EC VF vports. This includes changes in how eswitch SRIOV is managed. Previous on an embedded CPU platform the number of VFs provided when enabling the eswitch was always 0, host VFs vports are handled in the eswitch functions change event handler. Now track the number of EC VFs as well, so they can be handled properly in the enable/disable flows. There are only 3 marks available for use in xarrays, all 3 were already in use for this use case. EC VF vports are in a known range so we can access them by index instead of marks.

2023-06-10net/mlx5: Update vport caps query/set for EC VFsDaniel Jurgens3-8/+19
These functions are for query/set by vport, there was an underlying assumption that vport was equal to function ID. That's not the case for EC VF functions. Set the ec_vf_function bit accordingly.

Add ec_vf_vport_base to HCA Capabilities 2. This indicates the base vport of embedded CPU virtual functions that are connected to the eswitch. Add ec_vf_function to query/set_hca_caps. If set this indicates accessing a virtual function on the embedded CPU by function ID. This should only be used with other_function set to 1.

2023-06-09s390/dasd: Use correct lock while counting channel queue lengthJan Höppner1-2/+2
The lock around counting the channel queue length in the BIODASDINFO ioctl was incorrectly changed to the dasd_block->queue_lock with commit 583d6535cb9d ("dasd: remove dead code"). This can lead to endless list iterations and a subsequent crash. The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used. Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.

2023-06-09tools/virtio: use canonical ftrace pathRoss Zwisler2-5/+9
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.

2023-06-09wifi: cfg80211: remove links only on APJohannes Berg1-1/+8
Since links are only controlled by userspace via cfg80211 in AP mode, also only remove them from the driver in that case.

2023-06-09wifi: mac80211: take lock before setting vif linksBenjamin Berg1-1/+8
ieee80211_vif_set_links requires the sdata->local->mtx lock to be held. Add the appropriate locking around the calls in both the link add and remove handlers. This causes a warning when e.g. ieee80211_link_release_channel is called via ieee80211_link_stop from ieee80211_vif_update_links.

2023-06-09wifi: cfg80211: fix link del callback to call correct handlerBenjamin Berg1-3/+3
The wrapper function was incorrectly calling the add handler instead of the del handler. This had no negative side effect as the default handlers are essentially identical.

2023-06-09wifi: mac80211: fix link activation settings orderJohannes Berg1-2/+2
In the normal MLME code we always call ieee80211_mgd_set_link_qos_params() before ieee80211_link_info_change_notify() and some drivers, notably iwlwifi, rely on that as they don't do anything (but store the data) in their conf_tx. Fix the order here to be the same as in the normal code paths, so this isn't broken.

2023-06-09wifi: cfg80211: fix double lock bug in reg_wdev_chan_valid()Dan Carpenter1-3/+0
The locking was changed recently so now the caller holds the wiphy_lock() lock. Taking the lock inside the reg_wdev_chan_valid() function will lead to a deadlock.

2023-06-09net/sched: cls_u32: Fix reference counter leak leading to overflowLee Jones1-8/+10
In the event of a failure in tcf_change_indev(), u32_set_parms() will immediately return without decrementing the recently incremented reference counter. If this happens enough times, the counter will rollover and the reference freed, leading to a double free which can be used to do 'bad things'. In order to prevent this, move the point of possible failure above the point where the reference counter is incremented. Also save any meaningful return values to be applied to the return data at the appropriate point in time. This issue was caught with KASAN.
