commit 1f9c6e1bc1ba5f8a10fcd6e99d170954d7c6d382 upstream.
There were several bugs here.
1) The done label was in the wrong place so we didn't copy any
information out when there was no command given.
2) We were using PAGE_SIZE as the size of the buffer instead of
"PAGE_SIZE - pos".
3) snprintf() returns the number of characters that would have been
printed if there were enough space. If there was not enough space
(and we had fixed the memory corruption bug dlaprell#2) then it would result
in an information leak when we do simple_read_from_buffer(). I've
changed it to use scnprintf() instead.
I also removed the initialization at the start of the function, because
I thought it made the code a little more clear.
