Hi Eric,

First of all, I am not lawyer. So, please do not treat anything below as
a legal advice.

Please take a look at [1], [2], [3] and [4]. AIUI this means that you
are allowed to release your new combined GELI code under the GPLv3.
Though I would suggest to confirm that with legal folks.

Copyrights and licenses

2020-04-12 Thread Eric McCorkle
As part of my work on FreeBSD (re)-integration, I would like to pull in
some code from the FreeBSD loader for GELI volumes.  Specifically, there
were some changes a while back that did things like store keys and check
new volumes against the cached keys.  I also noticed when I looked at
the current GELI code in grub that it doesn't seem to be zeroing out
keys properly when done with them.

This of course introduces a licensing question.  The FreeBSD loader code
is under the 2-clause BSD license.  I noticed that the current GELI code
seems to incorporate a 2-clause BSD banner; is it therefore acceptable
to simply update the banner?
