But unfortunately, this is always enabled on x86 when KPROBES # is enabled, and there's no way to turn it off. # # As kprobes is useful for observability of the kernel, it is useful to # have it enabled in production environments. But error injection should # be avoided. Add a prompt to the config to allow it to be disabled even # when kprobes is enabled, and get rid of the "def_bool y". # # This is a kernel debug feature (it's in Kconfig.debug), and should have # never been something enabled by default. # # Cc: stable@vger.kernel.org # Fixes: 540adea3809f6 ("error-injection: Separate error-injection from kprobe") # Signed-off-by: Steven Rostedt (Google) # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 a4412fdd49dc011bcc2c0d81ac4cab7457092650 # < make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux- defconfig # < make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux- help # make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux- olddefconfig # make -s -j 160 ARCH=xtensa O=/kisskb/build/linus_xtensa-defconfig_xtensa-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/xtensa-linux/bin/xtensa-linux- Completed OK # rm -rf /kisskb/build/linus_xtensa-defconfig_xtensa-gcc8 # Build took: 0:00:43.255379
