      signal: Ensure every siginfo we send has all bits initialized · 3eb0f519
      Eric W. Biederman authored
      Call clear_siginfo to ensure every stack allocated siginfo is properly
      initialized before being passed to the signal sending functions.
      Note: It is not safe to depend on C initializers to initialize struct
      siginfo on the stack because C is allowed to skip holes when
      initializing a structure.
      The initialization of struct siginfo in tracehook_report_syscall_exit
      was moved from the helper user_single_step_siginfo into
      tracehook_report_syscall_exit itself, to make it clear that the local
      variable siginfo gets fully initialized.
      In a few cases the scope of struct siginfo has been reduced to make it
      clear that siginfo siginfo is not used on other paths in the function
      in which it is declared.
      Instances of using memset to initialize siginfo have been replaced
      with calls clear_siginfo for clarity.

      signal/nds32: Use force_sig(SIGILL) in do_revisn · f6ed1eca
      Eric W. Biederman authored
      As originally committed do_revisn would deliver a siginfo for SIGILL
      with an si_code composed of random stack contents.  That makes no
      sense and is not something userspace can depend on.  So simplify
      the code and just use "force_sig(SIG_ILL, current)" instead.

      signal/nds32: Use force_sig in unhandled_interruption and unhandled_exceptions · be5c2ff0
      Eric W. Biederman authored
      Neither unhandled_interrupt nor unhandled_exceptions fills in any of the
      siginfo fields whend sending SIGKILL.  Further because it is SIGKILL
      even if all of the fields were filled out appropriately it would be impossible
      for the process to read any of the siginfo fields.  So simplfy things and
      just use force_sig instead of force_sig_info.

      signal/sh: Use force_sig_fault in hw_breakpoint_handler · 195bce73
      Eric W. Biederman authored
      The call chain is:
      So the signal number can only be SIGTRAP.
      In hw_breakpoint_handler rc is either NOTIFY_STOP or NOTIF_DONE
      both of which notifier_to_errno converts to 0.  So si_errno is 0.
      Historically si_addr was left unitialized in struct siginfo which is a
      bug.  There appears to be no consensus among the various architectures
      which value should be in si_addr.  So since no usable value has
      been returned up to this point return NULL in si_addr.
      Fixes: 4352fc1b ("sh: Abstracted SH-4A UBC support on hw-breakpoint core.")

      sparc: fix compat siginfo ABI regression · 32772c9e
      Dmitry V. Levin authored
      Starting with commit v4.14-rc1~60^2^2~1, a SIGFPE signal sent via kill
      results to wrong values in si_pid and si_uid fields of compat siginfo_t.
      This happens due to FPE_FIXME being defined to 0 for sparc, and at the
      same time siginfo_layout() introduced by the same commit returns
      SIL_FAULT for SIGFPE if si_code == SI_USER and FPE_FIXME is defined to 0.
      Fix this regression by removing FPE_FIXME macro and changing all its users
      to assign FPE_FLTUNK to si_code instead of FPE_FIXME.
      Note that FPE_FLTUNK is a new macro introduced by commit
      Tested with commit v4.16-11958-g16e205cf.
      This bug was found by strace test suite.
      In the discussion about FPE_FLTUNK on sparc David Miller said:
      > Eric, feel free to do something similar on Sparc.

      Pull irq affinity fixes from Thomas Gleixner:
        - Fix error path handling in the affinity spreading code
        - Make affinity spreading smarter to avoid issues on systems which
          claim to have hotpluggable CPUs while in fact they can't hotplug
          So instead of trying to spread the vectors (and thereby the
          associated device queues) to all possibe CPUs, spread them on all
          present CPUs first. If there are left over vectors after that first
          step they are spread among the possible, but not present CPUs which
          keeps the code backwards compatible for virtual decives and NVME
          which allocate a queue per possible CPU, but makes the spreading
          smarter for devices which have less queues than possible or present
      * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
        genirq/affinity: Spread irq vectors among present CPUs as far as possible
        genirq/affinity: Allow irq spreading from a given starting point
        genirq/affinity: Move actual irq vector spreading into a helper function
        genirq/affinity: Rename *node_to_possible_cpumask as *node_to_cpumask
        genirq/affinity: Don't return with empty affinity masks on error

      Pull OpenRISC fixlet from Stafford Horne:
       "Just one small thing here, it came in a while back but I didnt have
        anything in my 4.16 queue, still its the only thing for 4.17 so
        sending it alone.
        Small cleanup: remove unused __ARCH_HAVE_MMU define"

      Pull powerpc fixes from Michael Ellerman:
       - Fix crashes when loading modules built with a different
         CONFIG_RELOCATABLE value by adding CONFIG_RELOCATABLE to vermagic.
       - Fix busy loops in the OPAL NVRAM driver if we get certain error
         conditions from firmware.
       - Remove tlbie trace points from KVM code that's called in real mode,
         because it causes crashes.
       - Fix checkstops caused by invalid tlbiel on Power9 Radix.
       - Ensure the set of CPU features we "know" are always enabled is
         actually the minimal set when we build with support for firmware
         supplied CPU features.
      Thanks to: Aneesh Kumar K.V, Anshuman Khandual, Nicholas Piggin.
