I played a bit with KVM support for shadow stacks on AMD machines and I
rebased v1 patches along with John's SVM series
https://lore.kernel.org/kvm/20221012203910.204793-1-john.allen@xxxxxxx/
on top of v6.3-rc4 and Rick's series for host shadow stack support. I've
put this at
https://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux.git/log/?h=shstk/kvm
if anybody is interested. With this I could successfully run shadow stack
self test in a guest on an AMD Zen3 machine.
One thing I've noticed while rebasing is that John's patches move
cet_is_msr_accessible() from vmx/ to x86.c and I also had to make such move
for cet_is_ssp_msr_accessible().
Would make sense to have them available for both VMX and SVM from the
start.
Hi, Mike,
Yes, it makes sense to do so. I'll include the change in next version so
that John's patchset can
omit the work, thanks!
