2024-07-02gpiolib: unexport gpiochip_get_desc()Bartosz Golaszewski
This function has been deprecated for some time and is now only used within the GPIOLIB core. Remove it from the public header and unexport it as all current users are linked against the compilation unit where it is defined.

2024-06-10docs: gpio: prefer pread(2) for interrupt readingHuichun Feng
In legacy sysfs GPIO, when using poll(2) on the sysfs GPIO value for state change awaiting, a subsequent read(2) is required for consuming the event, which the doc recommends the use of lseek(2) or close-and-reopen to reset the file offset afterwards. The recommendations however, require at least 2 syscalls to consume the event. Gladly, use of pread(2) require only 1 syscall for the consumption. Let's advertise this usage by prioritizing its placement.

2024-05-30gpiolib: cdev: Cleanup kfifo_out() error handlingKent Gibson
The handling of kfifo_out() errors in read functions obscures any error. The error condition should never occur but, while a ret is set to -EIO, it is subsequently ignored and the read functions instead return the number of bytes copied to that point, potentially masking the fact that any error occurred. Log a warning and return -EIO in the case of a kfifo_out() error to make it clear something very odd is going on here.

2024-05-30gpiolib: cdev: Add INIT_KFIFO() for linereq eventsKent Gibson
The initialisation of the linereq events kfifo relies on the struct being zeroed and a subsequent call to kfifo_alloc(). The call to kfifo_alloc() is deferred until edge detection is first enabled for the linereq. If the kfifo is inadvertently accessed before the call to kfifo_alloc(), as was the case in a recently discovered bug, it behaves as a FIFO of size 1 with an element size of 0, so writes and reads to the kfifo appear successful but copy no actual data. As a defensive measure, initialise the kfifo with INIT_KFIFO() when the events kfifo is constructed. This initialises the kfifo element size and zeroes its data pointer, so any inadvertant access prior to the kfifo_alloc() call will trigger an oops.

2024-05-27gpio: prevent potential speculation leaks in gpio_device_get_desc()Hagar Hemdan
Userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do that by calling gpio_ioctl() with an offset out of range. Offset is copied from user and then used as an array index to get the gpio descriptor without sanitization in gpio_device_get_desc(). This change ensures that the offset is sanitized by using array_index_nospec() to mitigate any possibility of speculative information leaks.
