Very small complaints only.

LGTM otherwise.

Presuming all the testing works :-)

Still LGTM :-)

No objection from me.

None job, thanks!

Good catch!

Good move!

This is a step in a direction that I've been wanting to doo for quite some time; pin multiple output generators to processors. There is more, but I need to write it in detail first.

Looks OK to me!

I'm OK with this.

LGTM.

Against my better judgement, I kept the !DEV_RANDOM case as some folks insisted on being able to use preferred tools (ssh) even on insecure embedded hardware. I'm happy to se you fix it, if it means I don't get the flak ]:->

I'm happy with this, in principle. I defer on the kernel innards, but the general engineering looks sound.

Accept with delphi's changes.

OK. I like these diffs even better.

You need the security officer's say-so. I have a personal wavier when I do such commits myself (as I wrote the main random device), but this is non-transferrable, as far as I know.

LGTM.

Very good!

Nice work! Out for interest, why make the output generator selectable? Why not switch completely to Chacha20?

Overcome By Events.

I like this!

OK.

Looks good to me.

If it doesn't crash anything, then fine! I had stack problems at some point.

Commit r338324 closes this.

Sigh. I think I have all cem@'s review comments done now.

Rebase to top of HEAD.

Address cmem@'s review comments.

Adress some review concerns from cem@, and a few of my own while I'm here.

Fix documentation nit.

Add the "differential update" URI to the commit message.
Correct sys/conf/NOTES comment.

@delphij this is my comment copied over from https://reviews.freebsd.org/D16866?id=47165 that was unaddressed.

Thanks folks! Tinderbox build going, then I'll commit.

Address review commnts from delphij.

Apologies to delphij for abandoning the previous identical-looking commit. I was making a pig's ear of the archanist work.

This improves things drastically from what they were. More detailed work will follow.

Split into two separate commits as per review request.

Add the differential revision to the commit message.

There were a couple of changes which are largely cosmetic to do with #if logic. Change if you want, otherwise LGTM.

My "LGTM" assumes requested changes are taken.

LGTM

Looks good to me!

I'm happy with this.

(From hospital bed)

I will be able to help in a week or two when I get out of hospital - I'm about to have an operation.

That might be an idea. The actual PPS rate could be unable, as optimal choices may not be universal. I'm leery of turning off harvesting altogether as that would be a big POLA violation, but lessening the impact makes sense.

Do you mean not harvesting the packet contents?

I'm having a bit of a problem parsing this; could I please ask you to rephrase?
