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> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 50087112592016a3fc10b394a55f1f1a1bde6908 # < make -s -j 80 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- defconfig # make -s -j 80 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:175:2: warning: #warning check me!
