args->pitch and args->size may not be set by userspace, sometimes userspace only malloc args and not memset args to zero, then args->pitch and args->size is random, it is very danger to use pitch/size on gem. pitch's type is u32, and min_pitch's type is int, example, pitch is 0xffffffff, then pitch < min_pitch return true, then gem will alloc very very big bufffer, it would eat all the memory and cause kernel crash. Stop using pitch/size from args, calc them from other args. Signed-off-by: Mark Yao <mark.yao@rock-chips.com> |
