Support for sanitisers, including kcfi (CFI_CLANG), is in the works, but for now they're nightly-only options in rustc. Make RUST depend on !CFI_CLANG to prevent configuring a kernel without symmetrical support for kfi. Fixes: 2f7ab1267dc9 ("Kbuild: add Rust support") cc: stable@vger.kernel.org Signed-off-by: Conor Dooley --- This probably needs to go to stable. The correct fixes tag for that I am not sure of however, but since CFI_CLANG predates RUST, I blamed the commit adding rust support. --- init/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/init/Kconfig b/init/Kconfig index 8d4e836e1b6b..6cf05824859e 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -1895,6 +1895,7 @@ config RUST bool "Rust support" depends on HAVE_RUST depends on RUST_IS_AVAILABLE + depends on !CFI_CLANG depends on !MODVERSIONS depends on !GCC_PLUGINS depends on !RANDSTRUCT
