CONFIG_AS_MOVNTDQA was introduced by commit 0b1de5d5 ("drm/i915: Use SSE4.1 movntdqa to accelerate reads from WC memory"). We raise the minimal supported binutils version from time to time. The last bump was commit 1fb12b35 ("kbuild: Raise the minimum required binutils version to 2.21"). I confirmed the code in $(call as-instr,...) can be assembled by the binutils 2.21 assembler and also by LLVM integrated assembler. Remove CONFIG_AS_MOVNTDQA, which is always defined.

CONFIG_AS_SSSE3 was introduced by commit 75aaf4c3 ("x86/raid6: correctly check for assembler capabilities"). We raise the minimal supported binutils version from time to time.

I confirmed the code in $(call as-instr,...) can be assembled by the binutils 2.21 assembler and also by LLVM integrated assembler. Remove CONFIG_AS_SSSE3, which is always defined. I added ifdef CONFIG_X86 to lib/raid6/algos.c to avoid link errors on non-x86 architectures. lib/raid6/algos.c is built not only for the kernel but also for testing the library code from userspace. I added -DCONFIG_X86 to lib/raid6/test/Makefile to cator to this usecase. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Jason A.

You can build a user-space test program for the raid6 library code, like this: $ cd lib/raid6/test $ make The command in $(shell ...) function is evaluated by /bin/sh by default. (or, you can specify the shell by passing SHELL=<shell> from command line) Currently '>&/dev/null' is used to sink both stdout and stderr. Because this code is bash-ism, it only works when /bin/sh is a symbolic link to bash (this is the case on RHEL etc.) This does not work on Ubuntu where /bin/sh is a symbolic link to dash. I see lots of /bin/sh: 1: Syntax error: Bad fd number and warning "your version of binutils lacks ... support" Replace it with portable '>/dev/null 2>&1'.

It's definitely incorrect to mark the lock as taken even if down_read_killable() failed. This wass overlooked when we switched from down_read() to down_read_killable() because down_read() won't fail while down_read_killable() could.

lookup_node() uses gup to pin the page and get node information. It checks against ret>=0 assuming the page will be filled in. However it's also possible that gup will return zero, for example, when the thread is quickly killed with a fatal signal. Teach lookup_node() to gracefully return an error -EFAULT if it happens. Meanwhile, initialize "page" to NULL to avoid potential risk of exploiting the pointer.

When syzbot tries to figure out how to deduplicate bug reports, it prefers seeing a hint about a specific bug type (we can do better than just "UBSAN"). This lifts the handler reason into the UBSAN report line that includes the file path that tripped a check. Unfortunately, UBSAN does not provide function names.

Syzkaller expects kernel warnings to panic when the panic_on_warn sysctl is set. More work is needed here to have UBSan reuse the WARN infrastructure, but for now, just check the flag manually.
