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-11.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 a4412fdd49dc011bcc2c0d81ac4cab7457092650 # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- se7619_defconfig # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/sh/include/asm/hw_irq.h:6, from /kisskb/src/include/linux/irq.h:596, from /kisskb/src/include/asm-generic/hardirq.h:17, from /kisskb/src/arch/sh/include/asm/hardirq.h:9, from /kisskb/src/include/linux/hardirq.h:11, from /kisskb/src/include/linux/interrupt.h:11, from /kisskb/src/include/linux/serial_core.h:13, from /kisskb/src/include/linux/serial_sci.h:6, from /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:11: /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:105:31: note: in expansion of macro '_INTC_ARRAY' 105 | _INTC_ARRAY(vectors), _INTC_ARRAY(groups), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:15: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:106:9: note: in expansion of macro '_INTC_ARRAY' 106 | _INTC_ARRAY(mask_regs), _INTC_ARRAY(prio_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:15: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:107:9: note: in expansion of macro '_INTC_ARRAY' 107 | _INTC_ARRAY(sense_regs), _INTC_ARRAY(ack_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:15: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:107:34: note: in expansion of macro '_INTC_ARRAY' 107 | _INTC_ARRAY(sense_regs), _INTC_ARRAY(ack_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:15: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_se7619_defconfig_sh4-gcc11 # Build took: 0:00:44.778781
