Talk:Random number generation

References for update

Update reminder:

• Removing the Linux /dev/random blocking pool (Hacker News)
• Linux 4.13 will bring the next important updates for /dev/urandom. References:
  • LWN article ([1], incl [2] [3])
  • Related, systemd resolved the linked [4].

I've updated the page to account for the "Removing the Linux /dev/random blocking pool" changes, and I made the "See also" section link to the LWN article. The other links mentioned above are related to the introduction of the wait_for_random_bytes() kernel-internal API, which is a fairly minor detail that is not covered in the article. I think that should continue to be left out in favor of more relevant and important information. So I am considering this to be resolved. Synchronicity (talk) 08:11, 6 February 2023 (UTC)

I'm fine with the blocking pool updates, but prefer we cover the wait_for_random_bytes() in some way. Now CONFIG_WARN_ALL_UNSEEDED_RANDOM is disabled in the repo kernel, at the same time some configurations systemd by default uses a random_seed file in /boot. In combo it's not very transparent when which pool is used. A work-around could be to add instructions how to reseed the crng pool, like what happens on S3 resume.? --Indigo (talk) 22:08, 22 November 2024 (UTC)
