From: Thomas Huth <[email protected]>
The b64write code has a sanity check that the given lengths matches
the real length of the given data, and calculates the minimum of the
two values to be on the safe side. However, the address_space_write()
then uses the original value and ignores the calculated minimum. Use
out_len here to fix the problem.
Fixes: 70da30483e7 ("qtest: Use cpu address space instead of system memory")
