RHEL's kernel live patching uses upstream open source kpatch. The
sources to the kpatches are delivered in customer facing CDN repos at
the same time as the kpatch itself. We do not use proprietary code to
produce or apply the kpatches.
I can only speculate on whether RHEL kpatches would work on a CentOS
kernel, but my assumption is that they would not due to how they are
signed.
Is (well, was) the CentOS kernel identical at binary level to the RHEL
one?
If so, the same kpatch should be applicable to both RHEL and CentOS (the
old one).
But I seem to understand that the two kernels are *not* bytewise
identical, so a binary kpatch can not be applied the CentOS. Is this
true?
Anyway, RH kpatches are surely not compatible with CentOS stream. So I
asked if some project was started to provide live kernel patching to the
new CentOS project. If I don't miss something, this is not the case.
