This is a first patch set to support CLANG CFI (Control Flow Integrity) on ARM32.
Yay! Is CONFIG_CFI_PERMISSIVE=y expected to work with this series? I wasn't able to build with CONFIG_FTRACE=y; I got this link error: ld.lld: error: undefined symbol: ftrace_stub_graph (FWIW, I'm building against v6.8-rc2, maybe I need a different base?) But yes, I can boot and prototype mismatches are caught. Whee! :) Tested-by: Kees Cook <redacted> -Kees -- Kees Cook _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
