usb: xhci: Fix a potential null pointer dereference in xhci_debugfs_create_endpoint()

2019-06-22T06:09:09+00:00

[ Upstream commit 5bce256f0b528624a34fe907db385133bb7be33e ] In xhci_debugfs_create_slot(), kzalloc() can fail and dev->debugfs_private will be NULL. In xhci_debugfs_create_endpoint(), dev->debugfs_private is used without any null-pointer check, and can cause a null pointer dereference. To fix this bug, a null-pointer check is added in xhci_debugfs_create_endpoint(). This bug is found by a runtime fuzzing tool named FIZZER written by us.

USB: Fix chipmunk-like voice when using Logitech C270 for recording audio.

2019-06-19T06:00:13+00:00

commit bd21f0222adab64974b7d1b4b8c7ce6b23e9ea4d upstream. This patch fixes the chipmunk-like voice that manifets randomly when using the integrated mic of the Logitech Webcam HD C270. The issue was solved initially for this device by commit 2394d67e446b ("USB: add RESET_RESUME for webcams shown to be quirky") but it was then reintroduced by e387ef5c47dd ("usb: Add USB_QUIRK_RESET_RESUME for all Logitech UVC webcams"). This patch is to have the fix back. Signed-off-by: Marco Zatta Cc: stable Signed-off-by: Greg Kroah-Hartman

usb: dwc2: host: Fix wMaxPacketSize handling (fix webcam regression)

2019-06-19T06:00:13+00:00

commit babd183915e91a64e976b9e8ab682bb56624df76 upstream. In commit abb621844f6a ("usb: ch9: make usb_endpoint_maxp() return only packet size") the API to usb_endpoint_maxp() changed. It used to just return wMaxPacketSize but after that commit it returned wMaxPacketSize with the high bits (the multiplier) masked off. If you wanted to get the multiplier it was now up to your code to call the new usb_endpoint_maxp_mult() which was introduced in commit 541b6fe63023 ("usb: add helper to extract bits 12:11 of wMaxPacketSize"). Prior to the API change most host drivers were updated, but no update was made to dwc2. Presumably it was assumed that dwc2 was too simplistic to use the multiplier and thus just didn't support a certain class of USB devices. However, it turns out that dwc2 did use the multiplier and many devices using it were working quite nicely. That means that many USB devices have been broken since the API change. One such device is a Logitech HD Pro Webcam C920. Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it did call usb_maxpacket() which in turn called usb_endpoint_maxp(). Let's update dwc2 to work properly with the new API.

The tcpm.c state-machine is responsible to make sure vconn is off, but lets add a WARN to catch any cases where vconn is not off for some reason.

usb: ohci-da8xx: disable the regulator if the overcurrent irq fired

2019-06-15T09:53:01+00:00

[ Upstream commit d327330185f192411be80563a3c8398f4538cdb2 ] Historically the power supply management in this driver has been handled in two separate places in parallel. Device-tree users simply defined an appropriate regulator, while two boards with no DT support (da830-evm and omapl138-hawk) passed functions defined in their respective board files over platform data. These functions simply used legacy GPIO calls to watch the oc GPIO for interrupts and disable the vbus GPIO when the irq fires. Commit d193abf1c913 ("usb: ohci-da8xx: add vbus and overcurrent gpios") updated these GPIO calls to the modern API and moved them inside the driver. This however is not the optimal solution for the vbus GPIO which should be modeled as a fixed regulator that can be controlled with a GPIO. In order to keep the overcurrent protection available once we move the board files to using fixed regulators we need to disable the enable_reg regulator when the overcurrent indicator interrupt fires. Since we cannot call regulator_disable() from interrupt context, we need to switch to using a oneshot threaded interrupt.
