2023-03-23usb: dwc2: fix a devres leak in hw_enable upon suspend resumeFabrice Gasnier
Each time the platform goes to low power, PM suspend / resume routines call: __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset(). This adds a new devres each time. This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be called from udc_start(). This can be seen with tracing: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - go to low power - cat /sys/kernel/debug/tracing/trace A new "ADD" entry is found upon each low power cycle: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... A second issue is addressed here: - regulator_bulk_enable() is called upon each PM cycle (suspend/resume). - regulator_bulk_disable() never gets called. So the reference count for these regulators constantly increase, by one upon each low power cycle, due to missing regulator_bulk_disable() call in __dwc2_lowlevel_hw_disable(). The original fix that introduced the devm_add_action_or_reset() call, fixed an issue during probe, that happens due to other errors in dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL. Rather fix the error path: disable all the low level hardware in the error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable(). "ll_hw_enabled" should achieve the same (and is used currently in the remove() routine).

[How] During pre_asic_reset, driver will clear job fences and afterwards the fences' refcount will be reduced to 1. For drm_sched_jobs it will be released in job_free_cb, and for non-sched jobs like ib_test, it's meant to be released in sa_bo_free but only when the fences are signaled.

2023-03-23efi/libstub: Use relocated version of kernel's struct screen_infoArd Biesheuvel
In some cases, we expose the kernel's struct screen_info to the EFI stub directly, so it gets populated before even entering the kernel. This means the early console is available as soon as the early param parsing happens, which is nice. It also means we need two different ways to pass this information, as this trick only works if the EFI stub is baked into the core kernel image, which is not always the case. Huacai reports that the preparatory refactoring that was needed to implement this alternative method for zboot resulted in a non-functional efifb earlycon for other cases as well, due to the reordering of the kernel image relocation with the population of the screen_info struct, and the latter now takes place after copying the image to its new location, which means we copy the old, uninitialized state. So let's ensure that the same-image version of alloc_screen_info() produces the correct screen_info pointer, by taking the displacement of the loaded image into account.

"modprobe asix ; rmmod asix ; modprobe asix" fails with: sysfs: cannot create duplicate filename \ '/devices/virtual/mdio_bus/usb-003:004' Issue was originally reported by Anton Lundin on 2022-06-22 (link below). Chrome OS team hit the same issue in Feb, 2023 when trying to find work arounds for other issues with AX88172 devices. The use of devm_mdiobus_register() with usbnet devices results in the MDIO data being associated with the USB device. When the asix driver is unloaded, the USB device continues to exist and the corresponding "mdiobus_unregister()" is NOT called until the USB device is unplugged or unauthorized. So the next "modprobe asix" will fail because the MDIO phy sysfs attributes still exist. The 'easy' (from a design PoV) fix is to use the non-devm variants of mdiobus_* functions and explicitly manage this use in the asix_bind and asix_unbind function calls. I've not explored trying to fix usbnet initialization so devm_* stuff will work.

2023-03-22gve: Cache link_speed value from deviceJoshua Washington
The link speed is never changed for the uptime of a VM, and the current implementation sends an admin queue command for each call. Admin queue command invocations have nontrivial overhead (e.g., VM exits), which can be disruptive to users if triggered frequently. Our telemetry data shows that there are VMs that make frequent calls to this admin queue command. Caching the result of the original admin queue command would eliminate the need to send multiple admin queue commands on subsequent calls to retrieve link speed.

The Bluetooth mesh experimental feature enable was requiring the controller to be powered off in order for the Enable to work. Mesh is supposed to be enablable regardless of the controller state, and created an unintended requirement that the mesh daemon be started before the classic bluetoothd daemon.

2023-03-22Bluetooth: Fix race condition in hci_cmd_sync_clearMin Li
There is a potential race condition in hci_cmd_sync_work and hci_cmd_sync_clear, and could lead to use-after-free. For instance, hci_cmd_sync_work is added to the 'req_workqueue' after cancel_work_sync The entry of 'cmd_sync_work_list' may be freed in hci_cmd_sync_clear, and causing kernel panic when it is used in 'hci_cmd_sync_work'.

2023-03-22Bluetooth: hci_core: Detect if an ACL packet is in fact an ISO packetLuiz Augusto von Dentz
Because some transports don't have a dedicated type for ISO packets (see 14202eff214e1e941fefa0366d4c3bc4b1a0d500) they may use ACL type when in fact they are ISO packets. In the past this was left for the driver to detect such thing but it creates a problem when using the likes of btproxy when used by a VM as the host would not be aware of the connection the guest is doing it won't be able to detect such behavior, so this make bt_recv_frame detect when it happens as it is the common interface to all drivers including guest VMs. Fixes: 14202eff214e ("Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packet") Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
2023-03-22Bluetooth: hci_sync: Resume adv with no RPA when active scanZhengping Jiang
The address resolution should be disabled during the active scan, so all the advertisements can reach the host. The advertising has to be paused before disabling the address resolution, because the advertising will prevent any changes to the resolving list and the address resolution status. Skipping this will cause the hci error and the discovery failure. According to the bluetooth specification: "7.8.44 LE Set Address Resolution Enable command This command shall not be used when: - Advertising (other than periodic advertising) is enabled, - Scanning is enabled, or - an HCI_LE_Create_Connection, HCI_LE_Extended_Create_Connection, or HCI_LE_Periodic_Advertising_Create_Sync command is outstanding." If the host is using RPA, the controller needs to generate RPA for the advertising, so the advertising must remain paused during the active scan. If the host is not using RPA, the advertising can be resumed after disabling the address resolution.

Commit 7c3d5c20dc16 ("thermal/core: Add a generic thermal_zone_get_trip() function") stopped marking trip points with a zero temperature as disabled, behavior that was originally introduced in commit 81ad4276b505 ("Thermal: Ignore invalid trip points"). When using the mlxsw driver we see that when such trip points are not disabled, the thermal subsystem repeatedly tries to set the state of the associated cooling devices to the maximum state. Address this by restoring the original behavior and mark trip points with a zero temperature as disabled.
