How big are pages on arm64? Because we shouldn't get to this path if the string is bigger than PAGE_SIZE. But I know that on PPC64, PAGE_SIZE can be 64K, and 60612 is less than that. Thus, if we get there, the test is against signed int:16 (16 bit signed integer) that can go up to most 32768. If the string size is bigger than that, you would get this error. I would just say to ignore it. The only thing that can happen if someone does this is to trigger the warning. Unless if it is considered a form of DOS, where userspace just bombards the console by triggering this waring. But I don't see a problem with the actual design. There's no reason we should be processing string variables bigger than 32768 in vsprintf. -- Steve > %d%d%d%d%d%d%s%s%s%d%s%d%d%d%s%s%s%s%s%d%s%d%s%s%s%d%s%d%d%s%s%d%s%s%d%d%s%s%s%s > %s%d%s%d%d%s%s%s%d%d%d%d%d%s%s%s%s%d%s%s%s%s%d%d%d%d%d%d%d%s%s%s%s%d%s%d%s%d%s%d > %s%s%d%s%d%s%s%s%s%d%s%d%s%s%d%d%s%s%d%s%d%s%s%d%s%d%d%s%s%s%s%d%s%s%s%s%d%d%s%s > %s%d%s%d%s%s%d%d%d%d%d%s%s%s%s%s%s%s%d%d%d%s%d%s%d%d%s%d%d%d%s%s%d%d%d%s%s%d%s%d > %s%s%s%d%d%d%s%d%s%s%d%s%d%s%s%d%s%d%d%s%d%s%s%d%s%s%s%s%s%d%s%d%d%d%s%d%d%d%d%s > %d%s%d%d%d%s%s%s%s%s%d%s%s%s%s%d%d%d%s%d%s%d%d%s%d%s%s%d%d%d%s%d%s%d%d%s%s%s%d%s > %s%d%d%d%d%d%d%d%d%d%d%s%d%s%d%s%d%d%s%d%d%s%d%s%s%s%d%d%d%d%s%s%d%d%s%d%d%d%s%d > %d%s%d%d%d%d%s%s%d%s%s%d%d%d%s%s%s%s%s%s%s%s%s%d%s%d%d%s%d%s%s%d%s%s%s%s%d%d%d%d > %s%d%s%s%d%d%d%s%d%d%d%s%s%s%s%d%d%d%s%d%s%d%s%d%d%d%d%d%d%d%d%d%d%s%s%d%d%d%s%d > %d%d%s%s%s%s%s%s%s%d%d%d%d%s%s%d%s%s%d%s%s%s%s%d%d%s%d%d%s%d%d%s%d%d%d%s%s%s%s%d > %s%s%d%s%d%s%d%s%d%d%d%d%s%d%d%d%s%d%d%d%d%s%s%d%s%s%d%d%d%s%d%s%d%d%d%d%d%d%s%d > %s%s%d%d%s%d%d%d%s%s%d%s%d%s%d%s%d%d%s%d%s%s%s%s%s%d%s%s%d%d%d%s%s%d%d%s%s%d%s%d > %s%d%s%s%s% > [ 833.044728] ------------[ cut here ]------------ > [ 833.137184] precision 60612 too large > >
