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@xxxxxxxxx/
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.
