This is because the # guest may use the local form of the tlb invalidation instruction meaning # stale tlb entries would persist where it previously ran. This is handled # on guest entry in kvmppc_check_need_tlb_flush() which calls # flush_guest_tlb() to perform the tlb flush. # # Previously the generic radix__local_flush_tlb_lpid_guest() function was # used, however the functionality was reimplemented in flush_guest_tlb() # to avoid the trace_tlbie() call as the flushing may be done in real # mode. The reimplementation in flush_guest_tlb() was missing an erat # invalidation after flushing the tlb. # # This lead to observable memory corruption in the guest due to the # caching of stale translations. Fix this by adding the erat invalidation. # # Fixes: 70ea13f6e609 ("KVM: PPC: Book3S HV: Flush TLB on secondary radix threads") # Signed-off-by: Suraj Jitindar Singh <sjitindarsingh@gmail.com> #
