      sched/fair: Fix incorrect task group ->load_avg · b5a9b340
      Vincent Guittot authored
      A scheduler performance regression has been reported by Joseph Salisbury,
      which he bisected back to:
      
        3d30544f ("sched/fair: Apply more PELT fixes)
      
      The regression triggers when several levels of task groups are involved
      (read: SystemD) and cpu_possible_mask != cpu_present_mask.
      
      The root cause is that group entity's load (tg_child->se[i]->avg.load_avg)
      is initialized to scale_load_down(se->load.weight). During the creation of
      a child task group, its group entities on possible CPUs are attached to
      parent's cfs_rq (tg_parent) and their loads are added to the parent's load
      (tg_parent->load_avg) with update_tg_load_avg().
      
      But only the load on online CPUs will then be updated to reflect real load,
      whereas load on other CPUs will stay at the initial value.
      
      The result is a tg_parent->load_avg that is higher than the real load, the
      weight of group entities (tg_parent->se[i]->load.weight) on online CPUs is
      smaller than it should be, and the task group gets a less running time than
      what it could expect.
      
      ( This situation can be detected with /proc/sched_debug. The ".tg_load_avg"
        of the task group will be much higher than sum of ".tg_load_avg_contrib"
        of online cfs_rqs of the task group. )
      
      The load of group entities don't have to be intialized to something else
      than 0 because their load will increase when an entity is attached.

      KASAN stack instrumentation poisons stack redzones on function entry
      and unpoisons them on function exit. If a function exits abnormally
      (e.g. with a longjmp like jprobe_return()), stack redzones are left
      poisoned. Later this leads to random KASAN false reports.
      
      Unpoison stack redzones in the frames we are going to jump over
      before doing actual longjmp in jprobe_return().

      kprobes: Avoid false KASAN reports during stack copy · 9254139a
      Dmitry Vyukov authored
      Kprobes save and restore raw stack chunks with memcpy().
      With KASAN these chunks can contain poisoned stack redzones,
      as the result memcpy() interceptor produces false
      stack out-of-bounds reports.
      
      Use __memcpy() instead of memcpy() for stack copying.
      __memcpy() is not instrumented by KASAN and does not lead
      to the false reports.

      objtool: Skip all "unreachable instruction" warnings for gcov kernels · 9cfffb11
      Josh Poimboeuf authored
      Recently objtool has started reporting a few "unreachable instruction"
      warnings when CONFIG_GCOV is enabled for newer versions of GCC.  Usually
      this warning means there's some new control flow that objtool doesn't
      understand.  But in this case, objtool is correct and the instructions
      really are inaccessible.  It's an annoying quirk of gcov, but it's
      harmless, so it's ok to just silence the warnings.
      
      With older versions of GCC, it was relatively easy to detect
      gcov-specific instructions and to skip any unreachable warnings produced
      by them.  But GCC 6 has gotten craftier.
      
      Instead of continuing to play whack-a-mole with gcov, just use a bigger,
      more permanent hammer and disable unreachable warnings for the whole
      file when gcov is enabled.  This is fine to do because a) unreachable
      warnings are usually of questionable value; and b) gcov isn't used for
      production kernels and we can relax the checks a bit there.

      objtool: Improve rare switch jump table pattern detection · 3732710f
      Josh Poimboeuf authored
      GCC 6 added a new switch statement jump table optimization which makes
      objtool's life harder.  It looks like:
      
        mov [rodata addr],%reg1
        ... some instructions ...
        jmpq *(%reg1,%reg2,8)
      
      The optimization is quite rare, but objtool still needs to be able to
      identify the pattern so that it can follow all possible control flow
      paths related to the switch statement.
      
      In order to detect the pattern, objtool starts from the indirect jump
      and scans backwards through the function until it finds the first
      instruction in the pattern.  If it encounters an unconditional jump
      along the way, it stops and considers the pattern to be not found.
      
      As it turns out, unconditional jumps can happen, as long as they are
      small forward jumps within the range being scanned.
      
      This fixes the following warnings:
      
        drivers/infiniband/sw/rxe/rxe_comp.o: warning: objtool: rxe_completer()+0x2f4: sibling call from callable instruction with changed frame pointer
        drivers/infiniband/sw/rxe/rxe_resp.o: warning: objtool: rxe_responder()+0x10f: sibling call from callable instruction with changed frame pointer

      Pull befs fixes from Luis de Bethencourt:
       "I recently took maintainership of the befs file system [0]. This is
        the first time I send you a git pull request, so please let me know if
        all the below is OK.
      
        Salah Triki and myself have been cleaning the code and fixing a few
        small bugs.
      
        Sorry I couldn't send this sooner in the merge window, I was waiting
        to have my GPG key signed by kernel members at ELCE in Berlin a few
        days ago."

      Pull gcc plugins update from Kees Cook:
       "This adds a new gcc plugin named "latent_entropy". It is designed to
        extract as much possible uncertainty from a running system at boot
        time as possible, hoping to capitalize on any possible variation in
        CPU operation (due to runtime data differences, hardware differences,
        SMP ordering, thermal timing variation, cache behavior, etc).
      
        At the very least, this plugin is a much more comprehensive example
        for how to manipulate kernel code using the gcc plugin internals"
