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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 50087112592016a3fc10b394a55f1f1a1bde6908 # < make -s -j 24 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 24 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- FIT description: Linux 5.2.0-rc2-g500871125920 Created: Thu Jun 20 23:35:15 2019 Image 0 (kernel@0) Description: Linux 5.2.0-rc2-g500871125920 Created: Thu Jun 20 23:35:15 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4650948 Bytes = 4541.94 KiB = 4.44 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x80896410 Hash algo: sha1 Hash value: 4ab7b1fc05cd394a039a867d729a07e279c62c0d Image 1 (fdt@boston) Description: img,boston Device Tree Created: Thu Jun 20 23:35:15 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Thu Jun 20 23:35:15 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Thu Jun 20 23:35:15 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 4603 Bytes = 4.50 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 33e429f316125d86bb863c2fe8d9c42fbcf90bfb Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Thu Jun 20 23:35:15 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 5162 Bytes = 5.04 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 0c5db3f23ba8b80fafd8c8e4eacfcb8ad62a91ae Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Thu Jun 20 23:35:15 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/powerpc-fixes_mips-defconfig_mipsel # Build took: 0:02:03.766254
