commit 30d1872d9e upstream.
When using the string representation of a random counter as part of the base
name, ensure that it is no longer than 4 bytes.
Since we are repeatedly decrementing the counter in a loop until we have found a
unique base name, the counter may wrap around zero; therefore, it is not enough
to mask its higher bits before entering the loop, this must be done inside the
loop.
