sys/modules: fix standalone build for multiple modules

2025-08-23T04:58:40+00:00

Multiple Makefile miss opt_*.h and *_if.h header file. We fix it by
running make in sys/modules to build all modules.

Revert "modules: Add missing opt_*.h files for stand-alone compile"

2024-10-17T18:52:32+00:00

This reverts commit 1a37caeb076b9d31e13c54691d7f1eeb589798bb.

I'd overlooked 06c07e1203324bfe8ab4526c82dbb750864272d5 when I updated a
branch I'd previously committed but not updated. My search for this in
my tree before the commit was to a stale file...

Standalone compile that we at least create these opt_*.h files.

sys/conf: Introduce NOSAN_CFLAGS and NOSAN_C

2024-08-20T08:49:15+00:00

To simplify disabling the kernel sanitizers in some files add
NOSAN_CFLAGS and NOSAN_C variables. These are CFLAGS and NORMAL_C with
the sanitizer flags removed.

While here add MSAN_CFLAGS to simplify keeping KMSAN in kern_kcov.c

linux64: Fix the build on arm64 with bti checking

2024-06-05T09:23:40+00:00

When we enable checking for BTI on arm64 we need to include an ELF
note in all object files linked into a module.

As using objcopy from a binary to an ELF object file doesn't add the
note switch to using .incbin from an assembly file. This allows us to
add the needed note without affecting the included object.

sanitizers: Avoid building genassym.c and genoffset.c with sanitizers

2024-01-12T21:09:14+00:00

Some, particularly KASAN, may insert redzones around global symbols,
resulting in incorrect offset definitions because genassym.sh (ab)uses
symbol sizes to assign semantic meaning.

(Ideally I would be able to define this pattern in one place, but I
haven't found a way to define a GENSYM_CFLAGS that actually works for
all of the consumers (kern.post.mk, kmod.mk, sys/conf/files*).)

sys: ${CFLAGS:N-flto} -> ${CFLAGS:N-flto*}

2023-12-26T23:31:51+00:00

For the same reason as the original https://reviews.freebsd.org/D9659:
-flto=, -flto=full, and -flto=thin also produce the GIMPLE/bitcode
which is not supported by genassym, so filter those out as well.
