CONFIG_UBSAN_DIV_ZERO: Perform checking for integer divide-by-zero

General informations

The Linux kernel configuration item CONFIG_UBSAN_DIV_ZERO:

• prompt: Perform checking for integer divide-by-zero
• type: bool
• depends on: ($( CONFIG_cc-option,-fsanitize = CONFIG_integer-divide-by-zero )) && (! CONFIG_CC_IS_CLANG )
• defined in lib/Kconfig.ubsan
• found in Linux kernels: 5.11–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

This option enables -fsanitize=integer-divide-by-zero which checks for integer division by zero. This is effectively redundant with the kernel's existing exception handling, though it can provide greater debugging information under UBSAN_REPORT_FULL.
