I would love to see a perfect solution too. As I don't have the time for it, I took the time to get a working solution reviewed and pretty heavily tested. Reviewed by SO@, that is. >>> Also you can always compile in a module, you can not compile out >>> a 'standard' file. >>> >>> For now could you just add >>> options chacha #Required by arc4random, do not remove >>> to your kernel and move on?

I've been pretty angry n a few occasions when I'm trying to fix my own problems and I had to waste time sorting out tangential, avoidable problems. What's the difference between making this 'standard' in sys/files/conf and adding a compulsory change to ALL kernel files (apart from the fact that we miss the users' kernel configs)? We can even keep the module stubs in the code. Later, when/if arc4random(9) becomes a loadable module (I'd *LOVE* to see how we get that right without compromising the RNG early start), we can make it optional. That is a one line change to sys/conf/files. >> RC4 has been standard for many years. > Probably another rapid mode of design rather than a thoughful mode, we > have a chance to correct this here, and imho, should. Fix it, sure. What's wrong with doing that as a next step? Why does this change need to be held to ransom? >> Up until now, arc4random worked with unconditional RC4. > > And your wanting to just replace unconditional RC4 for unconditional chacha? > Or actuall, aleady did? Correct. Both counts. It was up on Phabricator for weeks, BTW.
