1176125 - Required steps to re-licence Samba MD4 code for Mozilla

Status: RESOLVED FIXED

(mozilla.org :: Licensing, task)

Description

[Andrew Bartlett]

I am working on bug #496234 and to fix this, I would like to replace the MD4 code here with code we know works.  In my case the code I trust is Samba's, and so I want to ask Andrew Tridgell (sole copyright holder on a old version of that code) for permission to licence it under an acceptable licence for Mozilla.

https://git.samba.org/samba.git/?p=samba.git;a=blob;f=source3/lib/md4.c;h=1c9c2e6ecd596b82b665e82b648088cfe11f0347;hb=ddb2ce9d8100bd2c0475032b99869624db36304c

I expect he will be glad to (I know him very well)

Can you advise what steps/proof you would require to accept such a re-licence?

Thanks,

Hi Andrew,

One fairly simple method would be to get Tridge to get himself an account on this Bugzilla with one of his well-known email addresses, and then just add a comment saying something like:

"I give permission for Mozilla to use the code found at the following URLs:

<list>

under the terms of the Mozilla Public License or another free software license most convenient to Mozilla. I confirm that I am the sole copyright holder of the code."

So we need to decide a) exactly what code we want (is it just the single file at the URL above?), and b) what license we want. Is the code around all MPLed? If so, MPL seems like the obvious choice, and retains the copyleft of the original code, which may be what is wanted.

Tridge didn't quite use the text I gave him, but can you see that https://bugzilla.mozilla.org/show_bug.cgi?id=496234#c8 is pretty clear.  Is that OK for you?

Thanks,

Andrew Bartlett

Yep, that's great. Here's the boilerplate you should use on the file:
