2023-10-25phy: mapphone-mdm6600: Fix pinctrl_pm handling for sleep pinsTony Lindgren
[ Upstream commit 3b384cc74b00b5ac21d18e4c1efc3c1da5300971 ] Looks like the driver sleep pins configuration is unusable. Adding the sleep pins causes the usb phy to not respond. We need to use the default pins in probe, and only set sleep pins at phy_mdm6600_device_power_off(). As the modem can also be booted to a serial port mode for firmware flashing, let's make the pin changes limited to probe and remove. For probe, we get the default pins automatically. We only need to set the sleep pins in phy_mdm6600_device_power_off() to prevent the modem from waking up because the gpio line glitches. If it turns out that we need a separate state for phy_mdm6600_power_on() and phy_mdm6600_power_off(), we can use the pinctrl idle state.

2023-10-25mmc: core: Capture correct oemid-bits for eMMC cardsAvri Altman
commit 84ee19bffc9306128cd0f1c650e89767079efeff upstream. The OEMID is an 8-bit binary number rather than 16-bit as the current code parses for. The OEMID occupies bits [111:104] in the CID register, see the eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from the legacy MMC specs (v3.31 and before). Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This means we ignore the impact on some of those old MMC cards that may be out there, but on the other hand this shouldn't be a problem as the OEMID seems not be an important feature for these cards.

[ Upstream commit ffe3b7837a2bb421df84d0177481db9f52c93a71 ] There is a slab-out-of-bounds Write bug in hid-holtek-kbd driver. The problem is the driver assumes the device must have an input but some malicious devices violate this assumption. Fix this by checking hid_device's input is non-empty before its usage.

2023-10-25gpio: timberdale: Fix potential deadlock on &tgpio->lockChengfeng Ye
[ Upstream commit 9e8bc2dda5a7a8e2babc9975f4b11c9a6196e490 ] As timbgpio_irq_enable()/timbgpio_irq_disable() callback could be executed under irq context, it could introduce double locks on &tgpio->lock if it preempts other execution units requiring the same locks. timbgpio_gpio_set() --> timbgpio_update_bit() --> spin_lock(&tgpio->lock) <interrupt> --> timbgpio_irq_disable() --> spin_lock_irqsave(&tgpio->lock) This flaw was found by an experimental static analysis tool I am developing for irq-related deadlock. To prevent the potential deadlock, the patch uses spin_lock_irqsave() on &tgpio->lock inside timbgpio_gpio_set() to prevent the possible deadlock scenario.

2023-10-25i40e: prevent crash on probe if hw registers have invalid valuesMichal Schmidt
commit fc6f716a5069180c40a8c9b63631e97da34f64a3 upstream. The hardware provides the indexes of the first and the last available queue and VF. From the indexes, the driver calculates the numbers of queues and VFs. In theory, a faulty device might say the last index is smaller than the first index. In that case, the driver's calculation would underflow, it would attempt to write to non-existent registers outside of the ioremapped range and crash. I ran into this not by having a faulty device, but by an operator error. I accidentally ran a QE test meant for i40e devices on an ice device. The test used 'echo i40e > /sys/...ice PCI device.../driver_override', bound the driver to the device and crashed in one of the wr32 calls in i40e_clear_hw. Add checks to prevent underflows in the calculations of num_queues and num_vfs. With this fix, the wrong device probing reports errors and returns a failure without crashing.

2023-10-25Bluetooth: vhci: Fix race when opening vhci deviceArkadiusz Bokowy
commit 92d4abd66f7080075793970fc8f241239e58a9e7 upstream. When the vhci device is opened in the two-step way, i.e.: open device then write a vendor packet with requested controller type, the device shall respond with a vendor packet which includes HCI index of created interface. When the virtual HCI is created, the host sends a reset request to the controller. This request is processed by the vhci_send_frame() function. However, this request is send by a different thread, so it might happen that this HCI request will be received before the vendor response is queued in the read queue. This results in the HCI vendor response and HCI reset request inversion in the read queue which leads to improper behavior of btvirt: > dmesg [1754256.640122] Bluetooth: MGMT ver 1.22 [1754263.023806] Bluetooth: MGMT ver 1.22 [1754265.043775] Bluetooth: hci1: Opcode 0x c03 failed: -110 In order to synchronize vhci two-step open/setup process with virtual HCI initialization, this patch adds internal lock when queuing data in the vhci_send_frame() function.

commit 427694cfaafa565a3db5c5ea71df6bc095dca92f upstream. When NCM is used with hosts like Windows PC, it is observed that there are multiple NTB's contained in one usb request giveback. Since the driver unwraps the obtained request data assuming only one NTB is present, we loose the subsequent NTB's present resulting in data loss. Fix this by checking the parsed block length with the obtained data length in usb request and continue parsing after the last byte of current NTB.

commit c153a4edff6ab01370fcac8e46f9c89cca1060c2 upstream. The code in find_pinctrl() takes a mutex and traverses a list of pinctrl structures. Later the caller bumps up reference count on the found structure. Such pattern is not safe as pinctrl that was found may get deleted before the caller gets around to increasing the reference count. Fix this by taking the reference count in find_pinctrl(), while it still holds the mutex.

commit e2cb5cc822b6c9ee72c56ce1d81671b22c05406a upstream. When the SMBus connection is attempted psmouse_smbus_init() sets the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will fallback to PS/2 mode, replacing the psmouse private data. This can cause issues on resume, since psmouse_smbus_reconnect() expects to find an instance of struct psmouse_smbus_dev in psmouse->private. The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus mode") psmouse_smbus_reconnect() started attempting to use more of the data structure. The commit was since reverted, not because it was at fault, but because there was found a better way of doing what it was attempting to do. Fix the problem by resetting the fast_reconnect pointer in psmouse structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2 mode is used.

When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug.

2023-10-25mcb: remove is_added flag from mcb_device structJorge Sanjuan Garcia
commit 0f28ada1fbf0054557cddcdb93ad17f767105208 upstream. When calling mcb_bus_add_devices(), both mcb devices and the mcb bus will attempt to attach a device to a driver because they share the same bus_type. This causes an issue when trying to cast the container of the device to mcb_device struct using to_mcb_device(), leading to a wrong cast when the mcb_bus is added. A crash occurs when freing the ida resources as the bus numbering of mcb_bus gets confused with the is_added flag on the mcb_device struct. The only reason for this cast was to keep an is_added flag on the mcb_device struct that does not seem necessary. The function device_attach() handles already bound devices and the mcb subsystem does nothing special with this is_added flag so remove it completely.

commit fd39d9668f2ce9f4b05ad55e8c8d80c098073e0b upstream. The ms5611 driver falsely rejects lots of MS5607-02BA03-50 chips with "PROM integrity check failed" because it doesn't accept a prom crc value of zero as legitimate. According to the datasheet for this chip (and the manufacturer's application note about the PROM CRC), none of the possible values for the CRC are excluded - but the current code in ms5611_prom_is_valid() ends with return crc_orig != 0x0000 && crc == crc_orig Discussed with the driver author (Tomasz Duszynski) and he indicated that at that time (2015) he was dealing with some faulty chip samples which returned blank data under some circumstances and/or followed example code which indicated CRC zero being bad. As far as I can tell this exception should not be applied anymore; We've got a few hundred custom boards here with this chip where large numbers of the prom have a legitimate CRC value 0, and do work fine, but which the current driver code wrongly rejects.
