2022-03-08ice: Fix error with handling of bonding MTUDave Ertman
When a bonded interface is destroyed, .ndo_change_mtu can be called during the tear-down process while the RTNL lock is held. This is a problem since the auxiliary driver linked to the LAN driver needs to be notified of the MTU change, and this requires grabbing a device_lock on the auxiliary_device's dev. Currently this is being attempted in the same execution context as the call to .ndo_change_mtu which is causing a dead-lock. Move the notification of the changed MTU to a separate execution context (watchdog service task) and eliminate the "before" notification.

2022-03-08ice: stop disabling VFs due to PF error responsesJacob Keller
The ice_vc_send_msg_to_vf function has logic to detect "failure" responses being sent to a VF. If a VF is sent more than ICE_DFLT_NUM_INVAL_MSGS_ALLOWED then the VF is marked as disabled. Almost identical logic also existed in the i40e driver. This logic was added to the ice driver in commit 1071a8358a28 ("ice: Implement virtchnl commands for AVF support") which itself copied from the i40e implementation in commit 5c3c48ac6bf5 ("i40e: implement virtual device interface"). Neither commit provides a proper explanation or justification of the check. In fact, later commits to i40e changed the logic to allow bypassing the check in some specific instances. The "logic" for this seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lack of resources, etc. Additionally, this causes the PF to log an info message for every failed VF response which may confuse users, and can spam the kernel log. This behavior is not documented as part of any requirement for our products and other operating system drivers such as the FreeBSD implementation of our drivers do not include this type of check. In fact, the change from dev_err to dev_info in i40e commit 18b7af57d9c1 ("i40e: Lower some message levels") explains that these messages typically don't actually indicate a real issue. It is quite likely that a user who hits this in practice will be very confused as the VF will be disabled without an obvious way to recover. We already have robust malicious driver detection logic using actual hardware detection mechanisms that detect and prevent invalid device usage. Remove the logic since its not a documented requirement and the behavior is not intuitive.

2022-03-08i40e: stop disabling VFs due to PF error responsesJacob Keller
The i40e_vc_send_msg_to_vf_ex (and its wrapper i40e_vc_send_msg_to_vf) function has logic to detect "failure" responses sent to the VF. If a VF is sent more than I40E_DEFAULT_NUM_INVALID_MSGS_ALLOWED, then the VF is marked as disabled. In either case, a dev_info message is printed stating that a VF opcode failed. This logic originates from the early implementation of VF support in commit 5c3c48ac6bf5 ("i40e: implement virtual device interface"). That commit did not go far enough. The "logic" for this behavior seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lacking resources, an unsupported operation, etc. This does not indicate a malicious VF. We already have a separate robust malicious VF detection which relies on hardware logic to detect and prevent a variety of behaviors. There is no justification for this behavior in the original implementation. In fact, a later commit 18b7af57d9c1 ("i40e: Lower some message levels") reduced the opcode failure message from a dev_err to a dev_info. In addition, recent commit 01cbf50877e6 ("i40e: Fix to not show opcode msg on unsuccessful VF MAC change") changed the logic to allow quieting it for expected failures. That commit prevented this logic from kicking in for specific circumstances. This change did not go far enough. The behavior is not documented nor is it part of any requirement for our products. Other operating systems such as the FreeBSD implementation of our driver do not include this logic. It is clear this check does not make sense, and causes problems which led to ugly workarounds. Fix this by just removing the entire logic and the need for the i40e_vc_send_msg_to_vf_ex function.

In some cases overloaded flag IAVF_FLAG_REINIT_ITR_NEEDED which should indicate that interrupts need to be completely reinitialized during reset leads to RTNL deadlocks using ethtool -C while a reset is in progress. To fix, it was added a new flag IAVF_FLAG_REINIT_MSIX_NEEDED used to trigger MSI-X reinit. New combined setting is fixed adopt after VF reset. This has been implemented by call reinit interrupt scheme during VF reset. Without this fix new combined setting has never been adopted.

Currently the uncore_freq_common_init() return one on success and zero on failure. There is only one caller and it has a "forgot to set the error code" bug. Change uncore_freq_common_init() to return negative error codes which makes the code simpler and avoids this kind of bug in the future.

The Yoga Tablet 1050F/L is a x86 ACPI tablet which ships with Android x86 as factory OS.

2022-03-08clk: at91: clk-master: remove dead codeClaudiu Beznea
Commit facb87ad7560 ("clk: at91: sama7g5: remove prescaler part of master clock") removed the master clock's prescaler from clock tree of SAMA7G5 as it has been discovered that there is a hardware bug when trying to change it at run-time (bug is described in description of commit facb87ad7560 ("clk: at91: sama7g5: remove prescaler part of master clock")). This was previously changed at CPUFreq driver request. Thus, with commit facb87ad7560 ("clk: at91: sama7g5: remove prescaler part of master clock") there is no need of code that handles run-time changes of master clock's prescaler, thus remove this code.

2022-03-08drivers/perf: Add Apple icestorm/firestorm CPU PMU driverMarc Zyngier
Add a new, weird and wonderful driver for the equally weird Apple PMU HW. Although the PMU itself is functional, we don't know much about the events yet, so this can be considered as yet another random number generator... Nonetheless, it can reliably count at least cycles and instructions in the usually wonky big-little way. For anything else, it of course supports raw event numbers.
