Hi!
This is the start of the stable review cycle for the 5.10.119 release. There are 163 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.
Is there some kind of back-story why we are doing massive changes to /dev/random? 5.19-rc1 is not even out, so third of those changes did not get much testing.
Did you miss the posting on the stable list that described all of this: https://lore.kernel.org/all/YouECCoUA6eZEwKf@zx2c4.com/
That describes _what_ is done, but not _why_ the patches needed to be backported to older kernels. Normally I would see those as enhancements, not as bug fixes. Given that we (ChromeOS) have been hit by rng related issues before (specifically boot stalls on some hardware), I am quite concerned about the possible impact of this series for stable releases.
Here is the missing information: This is required by NIST SP800-90B [1]. Without this set of changes, Linux distributions are expected to fail FIPS validation in the future.
