This reverts: commit 02acd399533e ("bnxt_en: parse result field when NVRAM package install fails") commit 22f5dba5065d ("bnxt_en: add an nvm test for hw diagnose") commit bafed3f231f7 ("bnxt_en: implement hw health reporter") These patches are still under discussion / I don't think they are right, and since the authors don't reply promptly let me lessen my load of "things I need to resolve before next release" and revert them.

2022-03-09e1000e: Print PHY register address when MDI read/write failsChen Yu1-4/+4
There is occasional suspend error from e1000e which blocks the system from further suspending. And the issue was found on a WhiskeyLake-U platform with I219-V: [ 20.078957] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x780 [e1000e] returns -2 [ 20.078970] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x170 returns -2 [ 20.078974] e1000e 0000:00:1f.6: PM: pci_pm_suspend+0x0/0x170 returned -2 after 371012 usecs [ 20.078978] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2 According to the code flow, this might be caused by broken MDI read/write to PHY registers. However currently the code does not tell us which register is broken. Thus enhance the debug information to print the offender PHY register. So the next the issue is reproduced, this information could be used for narrow down.

This aligns the behavior with FW when creating an FDB rule with wire vport destination but no source port matching. Until now such rules would fail on internal DR RX rule creation since the source and destination are the wire vport.

Fix a refcount use after free warning due to a race on command entry. Such race occurs when one of the commands releases its last refcount and frees its index and entry while another process running command flush flow takes refcount to this command entry. The process which handles commands flush may see this command as needed to be flushed if the other process released its refcount but didn't release the index yet. Fix it by adding the needed spin lock. It fixes the following warning trace: refcount_t: addition on 0; use-after-free.

2022-03-08ice: Fix error with handling of bonding MTUDave Ertman2-15/+15
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 Keller2-21/+0
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 Keller3-59/+9
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.

2022-03-08iavf: Fix adopting new combined settingMichal Maloszewski2-4/+10
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.
