Hi, Don't think I've seen this reported, but I get the following warnings for code that uses memset, memcpy, etc. while compiling an external kernel module against the current rawhide kernel: ./include/linux/fortify-string.h: In function ‘memset’: ./include/linux/fortify-string.h:201:24: warning: infinite recursion detected [-Winfinite-recursion] 201 | __FORTIFY_INLINE void *memset(void *p, int c, __kernel_size_t size) | ^~~~~~ ./include/linux/fortify-string.h:43:33: note: recursive call 43 | #define __underlying_memset __builtin_memset | ^ ./include/linux/fortify-string.h:209:16: note: in expansion of macro ‘__underlying_memset’ 209 | return __underlying_memset(p, c, size); | ^~~~~~~~~~~~~~~~~~~ The resulting module still works fine btw, afaict.
