Muchun Song 18534df419 gpiolib: Fix possible use after free on label ... gpiod_request_commit() copies the pointer to the label passed as an argument only to be used later. But there's a chance the caller could immediately free the passed string(e.g., local variable). This could trigger a use after free when we use gpio label(e.g., gpiochip_unlock_as_irq(), gpiochip_is_requested()). To be on the safe side: duplicate the string with kstrdup_const() so that if an unaware user passes an address to a stack-allocated buffer, we won't get the arbitrary label. Also fix gpiod_set_consumer_name(). Signed-off-by: Muchun Song <smuchun@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>		2018-11-05 08:54:42 +01:00
