      vfs: ioctl: prevent double-fetch in dedupe ioctl · 10eec60c
      Scott Bauer authored
      This prevents a double-fetch from user space that can lead to to an
      undersized allocation and heap overflow.

      Linus Torvalds authored
      This changes the vfs dentry hashing to mix in the parent pointer at the
      _beginning_ of the hash, rather than at the end.
      That actually improves both the hash and the code generation, because we
      can move more of the computation to the "static" part of the dcache
      setup, and do less at lookup runtime.
      It turns out that a lot of other hash users also really wanted to mix in
      a base pointer as a 'salt' for the hash, and so the slightly extended
      interface ends up working well for other cases too.
      Users that want a string hash that is purely about the string pass in a
      'salt' pointer of NULL.

      Add braces to avoid "ambiguous ‘else’" compiler warnings · 194dc870
      Linus Torvalds authored
      Some of our "for_each_xyz()" macro constructs make gcc unhappy about
      lack of braces around if-statements inside or outside the loop, because
      the loop construct itself has a "if-then-else" statement inside of it.
      The resulting warnings look something like this:
        drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’:
        drivers/gpu/drm/i915/i915_debugfs.c:2103:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses]
           if (ctx != dev_priv->kernel_context)
      even if the code itself is fine.
      Since the warning is fairly easy to avoid by adding a braces around the
      if-statement near the for_each_xyz() construct, do so, rather than
      disabling the otherwise potentially useful warning.
      (The if-then-else statements used in the "for_each_xyz()" constructs are
      designed to be inherently safe even with no braces, but in this case
      it's quite understandable that gcc isn't really able to tell that).
      This finally leaves the standard "allmodconfig" build with just a
      handful of remaining warnings, so new and valid warnings hopefully will
      stand out.

      Disable "frame-address" warning · 124a3d88
      Linus Torvalds authored
      Newer versions of gcc warn about the use of __builtin_return_address()
      with a non-zero argument when "-Wall" is specified:
        kernel/trace/trace_irqsoff.c: In function ‘stop_critical_timings’:
        kernel/trace/trace_irqsoff.c:433:86: warning: calling ‘__builtin_return_address’ with a nonzero argument is unsafe [-Wframe-address]
           stop_critical_timing(CALLER_ADDR0, CALLER_ADDR1);
        [ .. repeats a few times for other similar cases .. ]
      It is true that a non-zero argument is somewhat dangerous, and we do not
      actually have very many uses of that in the kernel - but the ftrace code
      does use it, and as Stephen Rostedt says:
       "We are well aware of the danger of using __builtin_return_address() of
        > 0.  In fact that's part of the reason for having the "thunk" code in
        x86 (See arch/x86/entry/thunk_{64,32}.S).  [..] it adds extra frames
        when tracking irqs off sections, to prevent __builtin_return_address()
        from accessing bad areas.  In fact the thunk_32.S states: 'Trampoline to
        trace irqs off.  (otherwise CALLER_ADDR1 might crash)'."
      For now, __builtin_return_address() with a non-zero argument is the best
      we can do, and the warning is not helpful and can end up making people
      miss other warnings for real problems.
      So disable the frame-address warning on compilers that need it.

      Pull spi updates from Mark Brown:
       "Quite a lot of cleanup and maintainence work going on this release in
        various drivers, and also a fix for a nasty locking issue in the core:
         - A fix for locking issues when external drivers explicitly locked
           the bus with spi_bus_lock() - we were using the same lock to both
           control access to the physical bus in multi-threaded I/O operations
           and exclude multiple callers.
           Confusion between these two caused us to have scenarios where we
           were dropping locks.  These are fixed by splitting into two
           separate locks like should have been done originally, making
           everything much clearer and correct.
         - Support for DMA in spi_flash_read().
         - Support for instantiating spidev on ACPI systems, including some
           test devices used in Windows validation.
         - Use of the core DMA mapping functionality in the McSPI driver.
         - Start of support for ThunderX SPI controllers, involving a very big
           set of changes to the Cavium driver.
         - Support for Braswell, Exynos 5433, Kaby Lake, Merrifield, RK3036,

      Disable "maybe-uninitialized" warning globally · 6e8d666e
      Linus Torvalds authored
      Several build configurations had already disabled this warning because
      it generates a lot of false positives.  But some had not, and it was
      still enabled for "allmodconfig" builds, for example.
      Looking at the warnings produced, every single one I looked at was a
      false positive, and the warnings are frequent enough (and big enough)
      that they can easily hide real problems that you don't notice in the
      noise generated by -Wmaybe-uninitialized.
      The warning is good in theory, but this is a classic case of a warning
      that causes more problems than the warning can solve.
      If gcc gets better at avoiding false positives, we may be able to
      re-enable this warning.  But as is, we're better off without it, and I
      want to be able to see the *real* warnings.

      ipmi: remove trydefaults parameter and default init · b07b58a3
      Tony Camuso authored
      Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
      the legacy port io space that was designated for ipmi. Architectures
      that do not map legacy port io can panic when trydefaults=1.
      Rather than implement build-time conditional exceptions for each
      architecture that does not map legacy port io, we have removed legacy
      port io from the driver.
      Parameter 'trydefaults' has been removed. Attempts to use it hereafter
      will evoke the "Unknown symbol in module, or unknown parameter" message.
      The patch was built against a number of architectures and tested for
      regressions and functionality on x86_64 and ARM64.

      arm64: arm: Fix-up the removal of the arm64 regs_query_register_name() prototype · fd6380b7
      Catalin Marinas authored
      Commit 0a8ea52c ("arm64: Add HAVE_REGS_AND_STACK_ACCESS_API
      feature") inadvertently removed the arch/arm prototype instead of the
      arm64 one introduced by the original patch. There should not be any
      bisection issues since this function is not called from anywhere else
      (it could as well be removed from arch/arm at some point).

      be2net: perform temperature query in adapter regardless of its interface state · d3480615
      Guilherme G. Piccoli authored
      The be2net driver performs fw temperature queries on be_worker() routine,
      which is executed each second for each be_adapter. There is a frequency
      threshold to avoid fw query to happens at each call to be_worker();
      instead, currently a fw query occurs once in 64 runs of the procedure.
      Nevertheless, this fw temperature query is invoked only for adapters which
      interface is up, so we can see I/O errors on read of hwmon counters from
      userspace (from tools like lm-sensors) in case we have adapters' functions
      which interface is down.
      This patch moves the fw query code to be invoked even if interface is down.
      No functional changes were introduced.

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.8 kernel cycle.  The big
        news is the completion of the chardev ABI which I'm very happy about
        and apart from that it's an ordinary, quite busy cycle.  The details
        are below.
        The patches are tested in linux-next for some time, patches to other
        subsystem mostly have ACKs.
        I got overly ambitious with configureing lines as input for IRQ lines
        but it turns out that some controllers have their interrupt-enable and
        input-enabling in orthogonal settings so the assumption that all IRQ
        lines are input lines does not hold.  Oh well, revert and back to the
        drawing board with that.
        Core changes:
         - The big item is of course the completion of the character device
           ABI.  It has now replaced and surpassed the former unmaintainable
           sysfs ABI: we can now hammer (bitbang) individual lines or sets of
           lines and read individual lines or sets of lines from userspace,
           and we can also register to listen to GPIO events from userspace.
           As a tie-in we have two new tools in tools/gpio: gpio-hammer and
           gpio-event-mon that illustrate the proper use of the new ABI.  As
           someone said: the wild west days of GPIO are now over.
         - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
           Kconfig symbols.  I'm patching hexagon, openrisc, powerpc, sh,
           unicore, ia64 and microblaze.  These are either ACKed by their
           maintainers or patched anyways after a grace period and no response
           from maintainers.
           Some archs (ARM) come in from their trees, and others (x86) are
           still not fixed, so I might send a second pull request to root it
           out later in this merge window, or just defer to v4.9.
         - The GPIO tools are moved to the tools build system.
        New drivers:
         - New driver for the MAX77620/MAX20024.
         - New driver for the Intel Merrifield.
         - Enabled PCA953x for the TI PCA9536.
         - Enabled PCA953x for the Intel Edison.
         - Enabled R8A7792 in the RCAR driver.
        Driver improvements:
         - The STMPE and F7188x now supports the .get_direction() callback.
         - The Xilinx driver supports setting multiple lines at once.
         - ACPI support for the Vulcan GPIO controller.
         - The MMIO GPIO driver supports device tree probing.
         - The Acer One 10 is supported through the _DEP ACPI attribute.
         - A major cleanup of the OF/DT support code.  It is way easier to
           read and understand now, probably this improves performance too.
         - Drop a few redundant .owner assignments.
         - Remove CLPS711x boardfile support: we are 100% DT"
