crypto: fix regression on randomFillSync #35723

jasnell · 2020-10-20T17:01:25Z

Node.js 15.0.0 included a regression on crypto.randomFillSync that needs a quick patch. We should do a quick 15.0.1 once this lands. This should be fast-tracked.

@jasnell a note about it fixing #35722 would be great for completeness

Please 👍 to fast-track.

@panva ... added the Fixes note

richardlau · 2020-10-20T17:11:00Z

Regression test? (I'm stepping away for dinner so don't block on it, but if you could add a regression test that would be great because obviously the regression wasn't covered by our existing tests).

LGTM.

That said, it's strange that this wasn't caught.
That also affects e.g.

const x = Buffer.from("hello");
const y = Buffer.from("world");
require('crypto').randomFillSync(y)

Perhaps something like that could be added to tests.

jasnell · 2020-10-20T17:43:48Z

It's concerning that none of the existing tests caught this particular variation. The regression test should cover that case @ChALkeR but we can extend it after this lands.

jasnell · 2020-10-20T17:44:37Z

Some unrelated flaky failures so far in CI. Once the full CI run completes I'll resume it.

jasnell · 2020-10-20T18:35:04Z

The ARM job in CI appeared to hang up.. not sure what's up there... restarting CI to hopefully get a green run on the flaky failures

jasnell · 2020-10-20T19:13:07Z

Sigh. Another unrelated flaky failure and ARM is still hanging behind a list of pending CI runs. Assuming those clear out today and we can get by the flaky failures, this is ready to land any time

jasnell · 2020-10-21T00:30:10Z

Still waiting on the arm CI to get unjammed before we can move forward with this.... (@nodejs/build)

rvagg · 2020-10-21T01:11:47Z

removed arm-fanned from the roster, I had to cancel a few people's builds, you should dismiss them for now

New test run complete, you've got a very flaky parallel/test-http2-respond-file-error-pipe-offset on linux for both runs, this one on alpine and centos, the last run on the other alpine. But I don't suppose that has anything to do with this change.
