NAK this. If the fix is not clear and the bug not too serious it is better
to disclose it than fail to fix it. The security team does not usually fix the
bugs, the experts in the various bits of code do.

NAK this too. If someone releases an exploit publically or it leaks we
want to be able to freely share it too. Your proposal would mean any but
those dumb enough to agree to this could share it. That is why the unless made
public is part of every generic NDA document on the planet.


The rest needs Linus to return from holiday for discussion and that'll
be a week or two. In the meantime you might want to define "disclose" as
I don't think we all agree on what it means as you've not defined who is and
isn't the linux security team and/or its helpers.
