| 2021-09-13 | compiler.h: drop fallback overflow checkers | Nick Desaulniers | 1 | -137/+3 | |
| Once upgrading the minimum supported version of GCC to 5.1, we can drop the fallback code for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW. This is effectively a revert of commit f0907827a8a9 ("compiler.h: enable builtin overflow checkers and add fallback code") Link: https://github.com/ClangBuiltLinux/linux/issues/1438#issuecomment-916745801 Suggested-by: Rasmus Villemoes <[email protected]> Signed-off-by: Nick Desaulniers <[email protected]> Acked-by: Kees Cook <[email protected]> Reviewed-by: Nathan Chancellor <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> | |||||
| 2018-07-11 | tools: bpf: make use of reallocarray | Jakub Kicinski | 1 | -0/+278 | |
| reallocarray() is a safer variant of realloc which checks for multiplication overflow in case of array allocation. Since it's not available in Glibc < 2.26 import kernel's overflow.h and add a static inline implementation when needed. Use feature detection to probe for existence of reallocarray.
