Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2164067 Upstream Status: merged into the linux.git commit 552d03a223eda3df84526ab2c1f4d82e15eaee7a Author: Stephan Müller <smueller@chronox.de> Date: Sun Nov 21 15:14:20 2021 +0100 crypto: jitter - consider 32 LSB for APT The APT compares the current time stamp with a pre-set value. The current code only considered the 4 LSB only. Yet, after reviews by mathematicians of the user space Jitter RNG version >= 3.1.0, it was concluded that the APT can be calculated on the 32 LSB of the time delta. Thi change is applied to the kernel. This fixes a bug where an AMD EPYC fails this test as its RDTSC value contains zeros in the LSB. The most appropriate fix would have been to apply a GCD calculation and divide the time stamp by the GCD. Yet, this is a significant code change that will be considered for a future update. Note, tests showed that constantly the GCD always was 32 on these systems, i.e. the 5 LSB were always zero (thus failing the APT since it only considered the 4 LSB for its calculation).
