…plate Setting both CONFIG_KPROBES=y and CONFIG_FORTIFY_SOURCE=y on ARM leads to a panic in memcpy() when injecting a kprobe despite the fixes found in commit e46daee ("ARM: 8806/1: kprobes: Fix false positive with FORTIFY_SOURCE") and commit 0ac569b ("ARM: 8834/1: Fix: kprobes: optimized kprobes illegal instruction"). arch/arm/include/asm/kprobes.h effectively declares the target type of the optprobe_template_entry assembly label as a u32 which leads memcpy()'s __builtin_object_size() call to determine that the pointed-to object is of size four. However, the symbol is used as a handle for the optimised probe assembly template that is at least 96 bytes in size. The symbol's use despite its type blows up the memcpy() in ARM's arch_prepare_optimized_kprobe() with a false-positive fortify_panic() when it should instead copy the optimised probe template into place: ``` $ sudo perf probe -a aspeed_g6_pinctrl_probe [ 158.457252] detected buffer overflow in memcpy [ 158.458069] ------------[ cut here ]------------ [ 158.458283] kernel BUG at lib/string.c:1153!
