When passing a big integer value to fcntl.ioctl this might result in
OverflowError: signed integer is greater than maximum
. Traditionally ioctl(3) takes a pointer as third argument. The fcntl module however uses an int (format specifier 'i') which is too small to hold a pointer on 64 bit architectures.
The fix is to use 'k' (and an unsigned long) instead of 'i' (and an int). An unsigned long is suitable to hold a pointer value on AFAIK all platforms that matter today. (And it works on all platforms where int is already good enough, so the suggested change doesn't do any harm.)
A patch is attached. |
