* kconfig: Add support for -Wimplicit-fallthroughGustavo A. R. Silva2021-11-142-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang. The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH, which is enabled by default. Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This bugfix only appears in Clang 14.0.0, so older versions still contain the bug and -Wimplicit-fallthrough won't be enabled for them, for now. This concludes a long journey and now we are finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) Link: https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 [1] Link: https://bugs.llvm.org/show_bug.cgi?id=51094 [2] Link: https://github.com/KSPP/linux/issues/115 Link: https://github.com/ClangBuiltLinux/linux/issues/236 Co-developed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Kees Cook <keescook@chromium.org> Co-developed-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Gustavo A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 8779e05ba8aa ("parisc: Fix ptrace check on syscall return") fixed testing of TI_FLAGS. This uncovered a bug in the test mask. syscall_restore_rfi is only used when the kernel needs to exit to usespace with single or block stepping and the recovery counter enabled. The test however used _TIF_SYSCALL_TRACE_MASK, which includes a lot of bits that shouldn't be tested here. Fix this by using TIF_SINGLESTEP and TIF_BLOCKSTEP directly. I encountered this bug by enabling syscall tracepoints. Both in qemu and on real hardware. As soon as i enabled the tracepoint (sys_exit_read, but i guess it doesn't really matter which one), i got random page faults in userspace almost immediately.

It occurred to me that this might be a problem in set_pte_at(). MIPS and some other architectures do cache flushes when installing PTEs with the present bit set. Here I have adapted the code in update_mmu_cache() to flush the kernel mapping when the kernel flush is deferred, or when the kernel mapping may alias with the user mapping. This simplifies calls to update_mmu_cache(). I also changed the barrier in set_pte() from a compiler barrier to a full memory barrier. I know this change is not sufficient to fix the problem. It might not be needed. I have had a few days of operation with 5.14.16 to 5.15.1 and haven't seen any random segmentation faults on rp3440 or c8000 so far.

Their address were not resolved to function names and instead only the address was printed. Debugging shows that the culprit is is_ksym_addr() which is called by the backtrace functions to check if an address belongs to a function in the kernel. The problem occurs only for CONFIG_KALLSYMS_ALL=y. When looking at is_ksym_addr() one can see that for CONFIG_KALLSYMS_ALL=y the function only tries to resolve the address via is_kernel() function, which checks like this: if (addr >= _stext && addr <= _end) return 1; On parisc the init functions are located before _stext, so this check fails. Other platforms seem to have all functions (including init functions) behind _stext. The following patch moves the _stext symbol at the beginning of the kernel and thus includes the init section. This fixes the check and does not seem to have any negative side effects on where the kernel mapping happens in the map_pages() function in arch/parisc/mm/init.c.

The best way forward that I see is to just remove all the checks, which also has the nice side-effect of slightly improving the startup time for 'make'. The -mtune=marvell-f option was apparently never supported by any mainline compiler, and the custom Codesourcery gcc build that did support is now too old to build kernels, so just use -mtune=xscale unconditionally for those. This should be safe to apply on all stable kernels, and will be required in order to keep building them with gcc-11 and higher.

This change has the side effect of changing how the kernel generates the device name. The assumption was a translatable 'reg' address is unique. However, in the case of the register-bit-led binding (and a few others) that is not the case. The 'mask' property must also be used in this case to make a unique device name.
