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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 50087112592016a3fc10b394a55f1f1a1bde6908 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:334.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:334.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) INFO: Uncompressed kernel (size 0x51858c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51858c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x51858c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x507e64) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.2.0-rc2-g500871125920 Created: Fri Jun 21 00:22:33 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2635742 Bytes = 2573.97 KiB = 2.51 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.2.0-rc2-g500871125920 Created: Fri Jun 21 00:22:33 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2664767 Bytes = 2602.31 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.2.0-rc2-g500871125920 Created: Fri Jun 21 00:22:33 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2666028 Bytes = 2603.54 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.2.0-rc2-g500871125920 Created: Fri Jun 21 00:22:33 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2664765 Bytes = 2602.31 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:43.337207
