Paolo,
I have two fixes for HV KVM which I would like to have included in
v4.4-rc1. The first one is a fix for a bug identified by Red Hat
which causes occasional guest crashes. The second one fixes a bug
which causes host stalls and timeouts under certain circumstances when
the host is configured for static 2-way micro-threading mode.
Thanks,
Paul.

Hi Paolo,
I have a small patch that I would like to get into 4.4 because it
fixes a bug which for certain kernel configs allows userspace to crash
the kernel. The configs are those for which KVM_BOOK3S_64_HV is set
(y or m) and KVM_BOOK3S_64_PR is not. Fortunately most distros that
enable KVM_BOOK3S_64_HV also enable KVM_BOOK3S_64_PR, as far as I can
tell.
Thanks,
Paul.

Paolo,
Here is a pull request for the fix for the bug in HV KVM where the
guest can hang host CPUs. Please send it to Linus for inclusion in
v4.5. (Or if you prefer, I can send it to Linus directly.)

Paolo,
Please do a pull from my kvm-ppc-fixes branch to get two bug fixes for
HV KVM on POWER9 machines. I would like them to go into 4.11.
One of the commits touches a PPC header file. I have verbal approval
from Michael Ellerman for this change to go via the KVM tree because
the affected definitions are only used by KVM.
Thanks,
Paul.

Fair enough! Conflicts are only really an issue for the first pull

Paolo,
Please do a pull from my kvm-ppc-fixes branch to get a small fix which
should go into 4.11 (via your master branch). It is just a check for
a NULL return from kzalloc in recently-added code.

Paolo,
Please do a pull from my kvm-ppc-fixes branch to get 3 commits that
should go into 4.12. Two of them fix failures to build for PR KVM
configurations, and one of them fixes a host crash that can occur on
POWER9 with radix guests.
Thanks,
Paul.

Paolo,
Please do a pull from my kvm-ppc-fixes branch to get 6 commits that I
would like to have go into 4.12, because they fix problems that could
cause hangs or crashes in the host (the first and last commit, but
only on POWER9 systems), or they fix problems that could allow guests
to potentially affect or disrupt the execution of the controlling
userspace (the other four). They are all marked to go to stable.
Thanks,
Paul.

Right, and the arch doesn't even match ... let's forget I asked. :)

Thanks.
On a related note, we still have the warning in virt/kvm/kvm_main.c
for CONFIG_SMP=n builds about the variable 'wait' being unused in
kvm_make_all_cpus_request(), because smp_call_function_many() doesn't
reference its 'wait' argument for uniprocessor configs.
This then causes the build to fail on powerpc because kvm_main.c
actually gets compiled under arch/powerpc, and we use -Werror for
arch/powerpc by default.
Paolo posted a sketch of a patch to make smp_call_function_many be a
static inline instead of a macro on UP, but it wasn't quite right and
no-one sent it anywhere. Paolo, if you're OK with me cleaning it up
and sending it on, I'll do that.
Paul.

The problem is that it breaks MIPS, which uses an unused variable. I'll
send an alternative patch that is confined in KVM.

Paolo,
If there is time, I would really like to get one more commit into
4.12, which fixes a bug where userspace can cause a host kernel crash
on POWER9. The fix is simple, just 2 lines. The cause was a typo
where we had 'i' where we should have had 'j' inside a loop. This is
in code which is new in 4.12.
Thanks,
Paul.

Because I couldn't pull this in time, I've cherry-picked the patch from
the branch and added "Cc: stable@vger.kernel.org".

Sure, would you also like me to include "[PATCH really v2] KVM: PPC:

Sure, would you also like me to include "[PATCH really v2] KVM: PPC:
Book3S: Fix race and leak in kvm_vm_ioctl_create_spapr_tce()"?

Yes, that would be good, thanks. I don't know of any exploit, but
this kind of thing can sometimes be exploitable in non-obvious ways.
Thanks,

Paolo,
Please do a pull from my kvm-ppc-fixes branch to get one more commit
for 4.13. It adds mutual exclusion between list_add_rcu and
list_del_rcu calls on the kvm->arch.spapr_tce_tables list. Without
this, userspace could potentially trigger corruption of the list and
cause a host crash or worse.
Thanks,
Paul.

Both Paolo and I had a vacation the week before final 4.13, so I merged
this for 3.14-rc1, sorry.

Pi is always a nice source of typos.
I guess it needs to go in 4.13-stable too? Paul, can you forward it to
stable@vger.kernel.org and include the "Fixes" information (which, by
the way, should probably be almost always included in -rc patches)?
Thanks,
Paolo
