gpioc: fix race in ioctl(GPIOCONFIGEVENTS) 2025-10-01T08:52:21+00:00 Ahmad Khalifa vexeduxr@FreeBSD.org 2025-09-30T11:09:50+00:00 4472ecb362b068400f26abfce2db2a2b10a88d95 A race can occur in gpioc_ioctl when it is called with GPIOCONFIGEVENTS closely followed by GPIOSETCONFIG. GPIOSETCONFIG can alter the priv->pins list, making it no longer empty and opening the door for access to priv->events while we are reallocating it. Fix this by holding priv->mtx while handling GPIOCONFIGEVENTS.
