In case of an OPAL error when # allocating the XIVE VPs, the kfree() call in kvmppc_xive_*create() # will result in a double free and corrupt the host memory. # # Fixes: 5422e95103cf ("KVM: PPC: Book3S HV: XIVE: Replace the 'destroy' method by a 'release' method") # Cc: stable@vger.kernel.org # v5.2+ # Signed-off-by: Cédric Le Goater # Tested-by: Michael Ellerman # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/6ea6998b-a890-2511-01d1-747d7621eb19@kaod.org # < /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 9798f4ea71eaf8eaad7e688c5b298528089c7bf8 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_maple_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- maple_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-fixes_maple_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1651:6: note: 'oldval' was declared here int oldval, ret; ^ Completed OK # rm -rf /kisskb/build/powerpc-fixes_maple_defconfig_powerpc-gcc5 # Build took: 0:02:33.404545
