Before buff is reused, I am not sure whether buff should be firstly
zeroed or not.
I don't see why it would, but if you want to zero it, that would be
a separate patch that is already needed on the existing code,
which never zeroes its buffers.
Sure. I agree with you. In the existing code, the buffers are not zeroed.
But to a buffer which is used for several times, it is good to zero it
before it is used again.
Can you add a new commit with the following?
1). Zero the buffers in the existing code
2). Add the zero functionality to your patch
From my perspective, it is good to the whole commit.
Please Jason and Leon comment on this.
Thanks,
