[PATCH 0/7] KVM: syzkaller fixes

From: Paolo Bonzini
Date: Wed Jun 01 2016 - 08:11:29 EST

These fix most of the bugs reported by Dmitry Vyukov a while back.
I couldn't reproduce one of the bugs (patch 7) but the fix is easy.
Probably, more VM ioctls should take kvm->lock, but I have not looked
at it yet.

I have only marked for stable the two patches that fix an oops. However,
all of patches 1-6 could go in 4.7-rc, I think.



Paolo Bonzini (7):
kvm: x86: avoid warning on repeated KVM_SET_TSS_ADDR
KVM: x86: avoid vmalloc(0) in the KVM_SET_CPUID
KVM: fail KVM_SET_VCPU_EVENTS with invalid exception number
KVM: irqfd: fix NULL pointer dereference in kvm_irq_map_gsi
KVM: x86: avoid vmalloc(0) in the KVM_SET_CPUID
KVM: x86: fix OOPS after invalid KVM_SET_DEBUGREGS
KVM: x86: protect KVM_CREATE_PIT/KVM_CREATE_PIT2 with kvm->lock
