* usb: core: add missing of_node_put() in usb_of_has_devices_or_graphJavier Carrasco2024-07-031-2/+5
| | | | | | | | | | | | | | | | | The for_each_child_of_node() macro requires an explicit call to of_node_put() on early exits to decrement the child refcount and avoid a memory leak. The child node is not required outsie the loop, and the resource must be released before the function returns. Add the missing of_node_put().

* USB: core: Fix duplicate endpoint bug by clearing reserved bits in the ↵Alan Stern2024-07-031-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | descriptor Syzbot has identified a bug in usbcore (see the Closes: tag below) caused by our assumption that the reserved bits in an endpoint descriptor's bEndpointAddress field will always be 0. As a result of the bug, the endpoint_is_duplicate() routine in config.c (and possibly other routines as well) may believe that two descriptors are for distinct endpoints, even though they have the same direction and endpoint number. This can lead to confusion, including the bug identified by syzbot (two descriptors with matching endpoint numbers and directions, where one was interrupt and the other was bulk). To fix the bug, we will clear the reserved bits in bEndpointAddress when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1 specs say these bits are "Reserved, reset to zero".) This requires us to make a copy of the descriptor earlier in usb_parse_endpoint() and use the copy instead of the original when checking for duplicates.

* xhci: always resume roothubs if xHC was reset during resumeMathias Nyman2024-07-031-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Usb device connect may not be detected after runtime resume if xHC is reset during resume. In runtime resume cases xhci_resume() will only resume roothubs if there are pending port events. If the xHC host is reset during runtime resume due to a Save/Restore Error (SRE) then these pending port events won't be detected as PORTSC change bits are not immediately set by host after reset. Unconditionally resume roothubs if xHC is reset during resume to ensure device connections are detected. Also return early with error code if starting xHC fails after reset. Issue was debugged and a similar solution suggested by Remi Pommarel. Using this instead as it simplifies future refactoring.

It is based on Mediatek's MTK T700 CPU. The module supports PCIe Gen3 x1 and USB 2.0 and 3.0 interfaces. The manufacturer states that USB is "for debug" but it has been confirmed to be fully functional, except for modem-control requests on some of the interfaces. USB device composition is controlled by AT+GTUSBMODE=<mode> command. Two values are currently supported for the <mode>: 40: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB 41: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB+AP(LOG)+AP(META) (default value) [ Note that the functions above are not ordered by interface number. ] Mode 40 corresponds to: T: Bus=03 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 22 Spd=480 MxCh= 0 D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=0e8d ProdID=7126 Rev= 0.01 S: Manufacturer=Fibocom Wireless Inc.

This leads to the following 2 problems: 1) The first ever value which is read by the register is always wrong 2) Every read operation, puts the register into forced mode and reads the data that were calculated in the previous conversion. This behaviour was tested in 2 ways: 1) The internal meas_status_0 register was read before and after every read operation in order to verify that the data were ready even before the register was set to forced mode and also to check that after the forced mode was set the new data were not yet ready. 2) Physically changing the temperature and measuring the temperature This commit adds the waiting time in between the set of the forced mode and the read of the data. The function is taken from the Bosch BME68x Sensor API [1].

Fix the reading and writing of hysteresis values by including thresholds into calculations. Hysteresis values that result in threshold clear values that are out of limits will be truncated. To check that the threshold clear values are correct, registers are read out using i2ctransfer and the corresponding temperature and relative humidity thresholds are calculated using the formulas in the datasheet.

In commit 42a2f6664e18 ("staging: vc04_services: Move global g_state to vchiq_state") the global state was moved to the vchiq_mgnt structures stored as a vchiq instance specific context. This conversion removed the helpers and instead replaced users of this helper with the assumption that the state is always available and the remote connected. The conversion does ensure that the state is always available, so some remaining state null pointer checks that remain are unnecessary, but the assumption that the remote is present and initialised is incorrect. Fix this broken assumption by re-introducing the logic that was lost during the conversion.

However, we have an off-by-one in the bitmask, so we're only setting the lower 6 bits of the address (USB addresses being 7 bits, and the hardware bitmask being bits 0:6). This means that device enumeration fails if the assigned address is greater than 64: [ 344.607255] usb 1-1: new high-speed USB device number 63 using ehci-platform [ 344.808459] usb 1-1: New USB device found, idVendor=cc00, idProduct=cc00, bcdDevice= 6.10 [ 344.817684] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 344.825671] usb 1-1: Product: Test device [ 344.831075] usb 1-1: Manufacturer: Test vendor [ 344.836335] usb 1-1: SerialNumber: 00 [ 349.917181] usb 1-1: USB disconnect, device number 63 [ 352.036775] usb 1-1: new high-speed USB device number 64 using ehci-platform [ 352.249432] usb 1-1: device descriptor read/all, error -71 [ 352.696740] usb 1-1: new high-speed USB device number 65 using ehci-platform [ 352.909431] usb 1-1: device descriptor read/all, error -71 Use the correct mask of 0x7f (rather than 0x3f), and generate this through the GENMASK macro, so we have numbers that correspond exactly to the hardware register definition.

It causes the following code is executed and deadlock occurs when trying to get the spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3: Remove DWC3 locking during gadget suspend/resume") that forgot to remove the lock of otg mode. So, remove the redundant lock of otg mode during gadget suspend/resume.

Otherwise, the child node's refcount is not decremented and the resource is not released. The current implementation of pmic_glink_ucsi_probe() makes use of the device_for_each_child_node(), but does not release the child node on early returns. Add the missing calls to fwnode_handle_put().
