      modpost: fix undefined behavior of is_arm_mapping_symbol() · d6b73266
      Masahiro Yamada authored
      The return value of is_arm_mapping_symbol() is unpredictable when "$"
      is passed in.
      
      strchr(3) says:
        The strchr() and strrchr() functions return a pointer to the matched
        character or NULL if the character is not found. The terminating null
        byte is considered part of the string, so that if c is specified as
        '\0', these functions return a pointer to the terminator.
      
      When str[1] is '\0', strchr("axtd", str[1]) is not NULL, and str[2] is
      referenced (i.e. buffer overrun).
      
      Test code
      ---------
      
        char str1[] = "abc";
        char str2[] = "ab";
      
        strcpy(str1, "$");
        strcpy(str2, "$");
      
        printf("test1: %d\n", is_arm_mapping_symbol(str1));
        printf("test2: %d\n", is_arm_mapping_symbol(str2));

      modpost: fix removing numeric suffixes · b5beffa2
      Alexander Lobakin authored
      With the `-z unique-symbol` linker flag or any similar mechanism,
      it is possible to trigger the following:
      
      ERROR: modpost: "param_set_uint.0" [vmlinux] is a static EXPORT_SYMBOL
      
      The reason is that for now the condition from remove_dot():
      
      if (m && (s[n + m] == '.' || s[n + m] == 0))
      
      which was designed to test if it's a dot or a '\0' after the suffix
      is never satisfied.
      This is due to that `s[n + m]` always points to the last digit of a
      numeric suffix, not on the symbol next to it (from a custom debug
      print added to modpost):
      
      param_set_uint.0, s[n + m] is '0', s[n + m + 1] is '\0'
      
      So it's off-by-one and was like that since 2014.
      
      Fix this for the sake of any potential upcoming features, but don't
      bother stable-backporting, as it's well hidden -- apart from that
      LD flag, it can be triggered only with GCC LTO which never landed
      upstream.

      kbuild: Fix include path in scripts/Makefile.modpost · 23a0cb8e
      Jing Leng authored
      When building an external module, if users don't need to separate the
      compilation output and source code, they run the following command:
      "make -C $(LINUX_SRC_DIR) M=$(PWD)". At this point, "$(KBUILD_EXTMOD)"
      and "$(src)" are the same.
      
      If they need to separate them, they run "make -C $(KERNEL_SRC_DIR)
      O=$(KERNEL_OUT_DIR) M=$(OUT_DIR) src=$(PWD)". Before running the
      command, they need to copy "Kbuild" or "Makefile" to "$(OUT_DIR)" to
      prevent compilation failure.
      
      So the kernel should change the included path to avoid the copy operation.

       - Enable DM core bioset's per-cpu bio cache if QUEUE_FLAG_POLL set.
         This change improves DM's hipri bio polling (REQ_POLLED) performance
         by 7 - 20% depending on the system.
      
       - Update DM core to use jump_labels to further reduce cost of unlikely
         branches for zoned block devices, dm-stats and swap_bios throttling.
      
       - Various DM core changes to reduce bio-based DM overhead and simplify
         IO accounting.
      
       - Fundamental DM core improvements to dm_io reference counting and the
         elimination of using bio_split()+bio_chain() -- instead DM's
         bio-based IO accounting is updated to account that a split occurred.
      
       - Improve DM core's abnormal bio processing to do less work.
      
       - Improve DM core's hipri polling support to use a single list rather
         than an hlist.
      
       - Update DM core to pass NULL bdev to bio_alloc_clone() so that
         initialization that isn't useful for DM can be elided.
      
       - Add cond_resched to DM stats' various loops that loop over all
         entries.
      
       - Fix incorrect error code return from DM integrity's constructor.
      
       - Make DM crypt's printing of the key constant-time.
      
       - Update bio-based DM multipath to provide high-resolution timer to the
         Historical Service Time (HST) path selector.

      Pull nfsd updates from Chuck Lever:
       "We introduce 'courteous server' in this release. Previously NFSD would
        purge open and lock state for an unresponsive client after one lease
        period (typically 90 seconds). Now, after one lease period, another
        client can open and lock those files and the unresponsive client's
        lease is purged; otherwise if the unresponsive client's open and lock
        state is uncontended, the server retains that open and lock state for
        up to 24 hours, allowing the client's workload to resume after a
        lengthy network partition.
      
        A longstanding issue with NFSv4 file creation is also addressed.
        Previously a file creation can fail internally, returning an error to
        the client, but leave the newly created file in place as an artifact.
        The file creation code path has been reorganized so that internal
        failures and race conditions are less likely to result in an unwanted
        file creation.
      
        A fault injector has been added to help exercise paths that are run
        during kernel metadata cache invalidation. These caches contain
        information maintained by user space about exported filesystems. Many
        of our test workloads do not trigger cache invalidation.
      
        There is one patch that is needed to support PREEMPT_RT and a fix for

       - It was time to tidy up kernel/module.c and one way of starting with
         that effort was to split it up into files. At my request Aaron Tomlin
         spearheaded that effort with the goal to not introduce any functional
         at all during that endeavour. The penalty for the split is +1322
         bytes total, +112 bytes in data, +1210 bytes in text while bss is
         unchanged. One of the benefits of this other than helping make the
         code easier to read and review is summoning more help on review for
         changes with livepatching so kernel/module/livepatch.c is now pegged
         as maintained by the live patching folks.

       - Aaron added module unload taint tracking (MODULE_UNLOAD_TAINT_TRACKING),
         to enable tracking unloaded modules which did taint the kernel.
      
       - Christophe Leroy added CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC
         which lets architectures to request having modules data in vmalloc
         area instead of module area. There are three reasons why an
         architecture might want this:
      
          a) On some architectures (like book3s/32) it is not possible to
             protect against execution on a page basis. The exec stuff can be
             mapped by different arch segment sizes (on book3s/32 that is 256M
             segments). By default the module area is in an Exec segment while
             vmalloc area is in a NoExec segment. Using vmalloc lets you muck
             with module data as NoExec on those architectures whereas before
             you could not.
      
          b) By pushing more module data to vmalloc you also increase the
             probability of module text to remain within a closer distance
             from kernel core text and this reduces trampolines, this has been
             reported on arm first and powerpc folks are following that lead.
      
          c) Free'ing module_alloc() (Exec by default) area leaves this
             exposed as Exec by default, some architectures have some security
             enhancements to set this as NoExec on free, and splitting module
             data with text let's future generic special allocators be added
             to the kernel without having developers try to grok the tribal
             knowledge per arch. Work like Rick Edgecombe's permission vmalloc
             interface [0] becomes easier to address over time.

      Pull sysctl updates from Luis Chamberlain:
       "For two kernel releases now kernel/sysctl.c has been being cleaned up
        slowly, since the tables were grossly long, sprinkled with tons of
        #ifdefs and all this caused merge conflicts with one susbystem or
        another.
      
        This tree was put together to help try to avoid conflicts with these
        cleanups going on different trees at time. So nothing exciting on this
        pull request, just cleanups.
      
        Thanks a lot to the Uniontech and Huawei folks for doing some of this
        nasty work"

      Pull asm-generic updates from Arnd Bergmann:
       "The asm-generic tree contains three separate changes for linux-5.19:
      
         - The h8300 architecture is retired after it has been effectively
           unmaintained for a number of years. This is the last architecture
           we supported that has no MMU implementation, but there are still a
           few architectures (arm, m68k, riscv, sh and xtensa) that support
           CPUs with and without an MMU.
      
         - A series to add a generic ticket spinlock that can be shared by
           most architectures with a working cmpxchg or ll/sc type atomic,
           including the conversion of riscv, csky and openrisc. This series
           is also a prerequisite for the loongarch64 architecture port that
           will come as a separate pull request.
      
         - A cleanup of some exported uapi header files to ensure they can be
           included from user space without relying on other kernel headers"

        powerpc: add asm/stat.h to UAPI compile-test coverage
        mips: add asm/stat.h to UAPI compile-test coverage
