2024-03-26usb: typec: ucsi: Check for notifications after initChristian A. Ehrhardt
The completion notification for the final SET_NOTIFICATION_ENABLE command during initialization can include a connector change notification. However, at the time this completion notification is processed, the ucsi struct is not ready to handle this notification. As a result the notification is ignored and the controller never sends an interrupt again. Re-check CCI for a pending connector state change after initialization is complete. Adjust the corresponding debug message accordingly. Fixes: 71a1fa0df2a3 ("usb: typec: ucsi: Store the notification mask") Cc: stable@vger.kernel.org Signed-off-by: Christian A.

Suppose we sleep on the PPM lock after clearing the EVENT_PENDING bit because the thread for another connector is executing a command.

2024-03-26usb: dwc3: Properly set system wakeupThinh Nguyen
If the device is configured for system wakeup, then make sure that the xHCI driver knows about it and make sure to permit wakeup only at the appropriate time. For host mode, if the controller goes through the dwc3 code path, then a child xHCI platform device is created. Make sure the platform device also inherits the wakeup setting for xHCI to enable remote wakeup. For device mode, make sure to disable system wakeup if no gadget driver is bound. We may experience unwanted system wakeup due to the wakeup signal from the controller PMU detecting connection/disconnection when in low power (D3). E.g. In the case of Steam Deck, the PCI PME prevents the system staying in suspend. Cc: stable@vger.kernel.org Reported-by: Guilherme G.

2024-03-26ASoC: SOF: ipc4/Intel: Fix delay reportingMark Brown
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The current version of delay reporting code can report incorrect values when paired with a firmware which enables this feature. Unfortunately there are several smaller issues that needed to be addressed to correct the behavior: Wrong information was used for the host side of counter For MTL/LNL used incorrect (in a sense that it was verified only on MTL) link side counter function. The link side counter needs compensation logic if pause/resume is used. The offset values were not refreshed from firmware. Finally, not strictly connected, but the ALSA buffer size needs to be constrained to avoid constant xrun from media players (like mpv) The series applies cleanly for 6.9 and 6.8.y stable, but older stable would need manual backport, but it is questionable if it is needed as MTL/LNL is missing features.

2024-03-26Revert "thermal: core: Don't update trip points inside the hysteresis range"Daniel Lezcano
It has been reported the commit cf3986f8c01d3 introduced a regression when the temperature is wavering in the hysteresis region. The mitigation stops leading to an uncontrolled temperature increase until reaching the critical trip point. Here what happens: * 'throttle' is when the current temperature is greater than the trip point temperature * 'target' is the mitigation level * 'passive' is positive when there is a mitigation, zero otherwise * these values are computed in the step_wise governor Configuration: trip point 1: temp=95°C, hyst=5°C (passive) trip point 2: temp=115°C, hyst=0°C (critical) governor: step_wise 1. The temperature crosses the way up the trip point 1 at 95°C - trend=raising - throttle=1, target=1 - passive=1 - set_trips: low=90°C, high=115°C 2. The temperature decreases but stays in the hysteresis region at 93°C - trend=dropping - throttle=0, target=0 - passive=1 Before cf3986f8c01d3 - set_trips: low=90°C, high=95°C After cf3986f8c01d3 - set_trips: low=90°C, high=115°C 3. The temperature increases a bit but stays in the hysteresis region at 94°C (so below the trip point 1 temp 95°C) - trend=raising - throttle=0, target=0 - passive=1 Before cf3986f8c01d3 - set_trips: low=90°C, high=95°C After cf3986f8c01d3 - set_trips: low=90°C, high=115°C 4. The temperature decreases but stays in the hysteresis region at 93°C - trend=dropping - throttle=0, target=THERMAL_NO_TARGET - passive=0 Before cf3986f8c01d3 - set_trips: low=90°C, high=95°C After cf3986f8c01d3 - set_trips: low=90°C, high=115°C At this point, the 'passive' value is zero, there is no mitigation, the temperature is in the hysteresis region, the next trip point is 115°C. As 'passive' is zero, the timer to monitor the thermal zone is disabled. Consequently if the temperature continues to increase, no mitigation will happen and it will reach the 115°C trip point and reboot. Before the optimization, the high boundary would have been 95°C, thus triggering the mitigation again and rearming the polling timer. The optimization make sense but given the current implementation of the step_wise governor collaborating via this 'passive' flag with the core framework it can not work. From a higher perspective it seems like there is a problem between the governor which sets a variable to be used by the core framework. That sounds akward and it would make much more sense if the core framework controls the governor and not the opposite. But as the devil hides in the details, there are some subtilities to be addressed before. Elaborating those would be out of the scope this changelog. So let's stay simple and revert the change first to fixup all broken mobile platforms. This reverts commit cf3986f8c01d3 ("thermal: core: Don't update trip points inside the hysteresis range") and takes a conflict with commit 0c0c4740c9d26 ("0c0c4740c9d2 thermal: trip: Use for_each_trip() in __thermal_zone_set_trips()") in drivers/thermal/thermal_trip.c into account.

2024-03-26gpio: cdev: sanitize the label before requesting the interruptBartosz Golaszewski
When an interrupt is requested, a procfs directory is created under "/proc/irq/<irqnum>/<label>" where <label> is the string passed to one of the request_irq() variants. What follows is that the string must not contain the "/" character or the procfs mkdir operation will fail. We don't have such constraints for GPIO consumer labels which are used verbatim as interrupt labels for GPIO irqs. We must therefore sanitize the consumer string before requesting the interrupt. Let's replace all "/" with ":".

2024-03-26selftests: vxlan_mdb: Fix failures with old libnetIdo Schimmel
Locally generated IP multicast packets (such as the ones used in the test) do not perform routing and simply egress the bound device. However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding: Fix failing tests with old libnet"), old versions of libnet (used by mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically, the library started using the option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6 ones are passing. Fix by specifying the source and destination MAC of the packets which will cause mausezahn to use a packet socket instead of an IP socket.

2024-03-26ALSA: sh: aica: reorder cleanup operations to avoid UAF bugsDuoming Zhou
The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could be rescheduled in the timer handler. As a result, the UAF bug will happen. The racy situation is shown below: (Thread 1) | (Thread 2) snd_aicapcm_pcm_close() | ... | run_spu_dma() //worker | mod_timer() flush_work() | del_timer() | aica_period_elapsed() //timer kfree(dreamcastcard->channel) | schedule_work() | run_spu_dma() //worker ... | dreamcastcard->channel-> //USE In order to mitigate this bug and other possible corner cases, call mod_timer() conditionally in run_spu_dma(), then implement PCM sync_stop op to cancel both the timer and worker. The sync_stop op will be called from PCM core appropriately when needed.

2024-03-26iommu/arm-smmu-v3: Fix access for STE.SHCFGMostafa Saleh
STE attributes(NSCFG, PRIVCFG, INSTCFG) use value 0 for "Use Icomming", for some reason SHCFG doesn't follow that, and it is defined as "0b01". Currently the driver sets SHCFG to Use Incoming for stage-2 and bypass domains. However according to the User Manual (ARM IHI 0070 F.b): When SMMU_IDR1.ATTR_TYPES_OVR == 0, this field is RES0 and the incoming Shareability attribute is used. This patch adds a condition for writing SHCFG to Use incoming to be compliant with the architecture, and defines ATTR_TYPE_OVR as a new feature discovered from IDR1. This also required to propagate the SMMU through some functions args. There is no need to add similar condition for the newly introduced function arm_smmu_get_ste_used() as the values of the STE are the same before and after any transition, so this will not trigger any change. (we already do the same for the VMID). Although this is a misconfiguration from the driver, this has been there for a long time, so probably no HW running Linux is affected by it.

2024-03-26USB: core: Fix deadlock in usb_deauthorize_interface()Alan Stern
Among the attribute file callback routines in drivers/usb/core/sysfs.c, the interface_authorized_store() function is the only one which acquires a device lock on an ancestor device: It calls usb_deauthorize_interface(), which locks the interface's parent USB device. The will lead to deadlock if another process already owns that lock and tries to remove the interface, whether through a configuration change or because the device has been disconnected. As part of the removal procedure, device_del() waits for all ongoing sysfs attribute callbacks to complete. But usb_deauthorize_interface() can't complete until the device lock has been released, and the lock won't be released until the removal has finished. The mechanism provided by sysfs to prevent this kind of deadlock is to use the sysfs_break_active_protection() function, which tells sysfs not to wait for the attribute callback.

When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function ljca_auxdev_release calls kfree(auxdev->dev.platform_data) to free the parameter data of the function ljca_new_client_device. The callers of ljca_new_client_device shouldn't call kfree() again in the error handling path to free the platform data. Fix this by cleaning up the redundant kfree() in all callers and adding kfree() the passed in platform_data on errors which happen before auxiliary_device_init() succeeds .

2024-03-26usb: typec: ucsi: Fix race between typec_switch and role_switchKrishna Kurapati
When orientation switch is enabled in ucsi glink, there is a xhci probe failure seen when booting up in host mode in reverse orientation. During bootup the following things happen in multiple drivers: a) DWC3 controller driver initializes the core in device mode when the dr_mode is set to DRD. It relies on role_switch call to change role to host. b) QMP driver initializes the lanes to TYPEC_ORIENTATION_NORMAL as a normal routine. It relies on the typec_switch_set call to get notified of orientation changes. c) UCSI core reads the UCSI_GET_CONNECTOR_STATUS via the glink and provides initial role switch to dwc3 controller. When booting up in host mode with orientation TYPEC_ORIENTATION_REVERSE, then we see the following things happening in order: a) UCSI gives initial role as host to dwc3 controller ucsi_register_port. Upon receiving this notification, the dwc3 core needs to program GCTL from PRTCAP_DEVICE to PRTCAP_HOST and as part of this change, it asserts GCTL Core soft reset and waits for it to be completed before shifting it to host. Only after the reset is done will the dwc3_host_init be invoked and xhci is probed. DWC3 controller expects that the usb phy's are stable during this process i.e., the phy init is already done. b) During the 100ms wait for GCTL core soft reset, the actual notification from PPM is received by ucsi_glink via pmic glink for changing role to host. The pmic_glink_ucsi_notify routine first sends the orientation change to QMP and then sends role to dwc3 via ucsi framework. This is happening exactly at the time GCTL core soft reset is being processed. c) When QMP driver receives typec switch to TYPEC_ORIENTATION_REVERSE, it then re-programs the phy at the instant GCTL core soft reset has been asserted by dwc3 controller due to which the QMP PLL lock fails in qmp_combo_usb_power_on. d) After the 100ms of GCTL core soft reset is completed, the dwc3 core goes for initializing the host mode and invokes xhci probe. But at this point the QMP is non-responsive and as a result, the xhci plat probe fails during xhci_reset. Fix this by passing orientation switch to available ucsi instances if their gpio configuration is available before ucsi_register is invoked so that by the time, the pmic_glink_ucsi_notify provides typec_switch to QMP, the lane is already configured and the call would be a NOP thus not racing with role switch.

2024-03-26USB: UAS: return ENODEV when submit urbs fail with device not attachedWeitao Wang
In the scenario of entering hibernation with udisk in the system, if the udisk was gone or resume fail in the thaw phase of hibernation. Its state will be set to NOTATTACHED. At this point, usb_hub_wq was already freezed and can't not handle disconnect event. Next, in the poweroff phase of hibernation, SYNCHRONIZE_CACHE SCSI command will be sent to this udisk when poweroff this scsi device, which will cause uas_submit_urbs to be called to submit URB for sense/data/cmd pipe. However, these URBs will submit fail as device was set to NOTATTACHED state. Then, uas_submit_urbs will return a value SCSI_MLQUEUE_DEVICE_BUSY to the caller. That will lead the SCSI layer go into an ugly loop and system fail to go into hibernation. On the other hand, when we specially check for -ENODEV in function uas_queuecommand_lck, returning DID_ERROR to SCSI layer will cause device poweroff fail and system shutdown instead of entering hibernation. To fix this issue, let uas_submit_urbs to return original generic error when submitting URB failed. At the same time, we need to translate -ENODEV to DID_NOT_CONNECT for the SCSI layer.

The commit to improve NMI stall debuggability: 344da544f177 ("x86/nmi: Print reasons why backtrace NMIs are ignored") ... has shown value, but widespread use has also identified a few opportunities for improvement. The systems have (as usual) shown far more creativity than that commit's author, demonstrating yet again that failing CPUs can do whatever they want. In addition, the current message format is less friendly than one might like to those attempting to use these messages to identify failing CPUs. Therefore, separately flag CPUs that, during the full time that the stack-backtrace request was waiting, were always in an NMI handler, were never in an NMI handler, or exited one NMI handler. Also, split the message identifying the CPU and the time since that CPU's last NMI-related activity so that a single line identifies the CPU without any other variable information, greatly reducing the processing overhead required to identify repeat-offender CPUs.

2024-03-26net: dsa: mt7530: fix improper frames on all 25MHz and 40MHz XTAL MT7530Arınç ÜNAL
The MT7530 switch after reset initialises with a core clock frequency that works with a 25MHz XTAL connected to it. For 40MHz XTAL, the core clock frequency must be set to 500MHz. The mt7530_pll_setup() function is responsible of setting the core clock frequency. Currently, it runs on MT7530 with 25MHz and 40MHz XTAL. This causes MT7530 switch with 25MHz XTAL to egress and ingress frames improperly. Introduce a check to run it only on MT7530 with 40MHz XTAL. The core clock frequency is set by writing to a switch PHY's register. Access to the PHY's register is done via the MDIO bus the switch is also on. Therefore, it works only when the switch makes switch PHYs listen on the MDIO bus the switch is on. This is controlled either by the state of the ESW_P1_LED_1 pin after reset deassertion or modifying bit 5 of the modifiable trap register. When ESW_P1_LED_1 is pulled high, PHY indirect access is used. That means accessing PHY registers via the PHY indirect access control register of the switch. When ESW_P1_LED_1 is pulled low, PHY direct access is used. That means accessing PHY registers via the MDIO bus the switch is on. For MT7530 switch with 40MHz XTAL on a board with ESW_P1_LED_1 pulled high, the core clock frequency won't be set to 500MHz, causing the switch to egress and ingress frames improperly. Run mt7530_pll_setup() after PHY direct access is set on the modifiable trap register. With these two changes, all MT7530 switches with 25MHz and 40MHz, and P1_LED_1 pulled high or low, will egress and ingress frames properly.
