Mapping # kernel memory is used when code patching with Strict RWX enabled. As # suggested by Chris Riedl, turning ftrace on and off does a large amount # of code patching so is a convenient way to see this kind of fault. # # Add a selftest to try and trigger this kind of a spurious fault. It # tests for 30 seconds which is usually long enough for the issue to show # up. # # Signed-off-by: Jordan Niethe <jniethe5@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210208032957.1232102-2-jniethe5@gmail.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 ea721ec55c8a4a166373978b9c8ce77374d684d6 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x69c584) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x69c584) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.11.0-rc2-81075-gea721ec5 Created: Thu Feb 11 03:02:49 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3237683 Bytes = 3161.80 KiB = 3.09 MiB Load Address: 00700000 Entry Point: 00701920 Image Name: Linux-5.11.0-rc2-81075-gea721ec5 Created: Thu Feb 11 03:02:50 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3239559 Bytes = 3163.63 KiB = 3.09 MiB Load Address: 00700000 Entry Point: 00701ba0 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc9 # Build took: 0:01:04.859070
