      perf/trace: Properly use u64 to hold event_id · 0022cedd
      Vince Weaver 提交于
      The 64-bit attr.config value for perf trace events was being copied into
      an "int" before doing a comparison, meaning the top 32 bits were
      being truncated.
      
      As far as I can tell this didn't cause any errors, but it did mean
      it was possible to create valid aliases for all the tracepoint ids
      which I don't think was intended.  (For example, 0xffffffff00000018
      and 0x18 both enable the same tracepoint).

      Currently we only allocate a single cpu hashtable for per-cpu
      swevents; do away with this optimization for it is fragile in the face
      of things like perf_pmu_migrate_context().
      
      The easiest thing is to make sure all CPUs are consistent wrt state.

      ftrace, perf: Avoid infinite event generation loop · d5b5f391
      Peter Zijlstra 提交于
      Vince's perf-trinity fuzzer found yet another 'interesting' problem.
      
      When we sample the irq_work_exit tracepoint with period==1 (or
      PERF_SAMPLE_PERIOD) and we add an fasync SIGNAL handler we create an
      infinite event generation loop:
      
        ,-> <IPI>
        |     irq_work_exit() ->
        |       trace_irq_work_exit() ->
        |         ...
        |           __perf_event_overflow() -> (due to fasync)
        |             irq_work_queue() -> (irq_work_list must be empty)
        '---------      arch_irq_work_raise()
      
      Similar things can happen due to regular poll() wakeups if we exceed
      the ring-buffer wakeup watermark, or have an event_limit.
      
      To avoid this, dis-allow sampling this particular tracepoint.
      
      In order to achieve this, create a special perf_perm function pointer
      for each event and call this (when set) on trying to create a
      tracepoint perf event.

        Error: expected type 5 but read 4
      
      The problem is with this part of the print_fmt:
      
        __print_symbolic(((REC->result) >> 24) & 0xff, ...
      
      The __print_symbolic() helper function's first parameter is the field to
      use to determine what symbol to print based on the value of the result.
      The parser can handle one operation, but it can not handle multiple
      operations ('>>' and '&').
      
      Add code to process all operations for the field argument for
      __print_symbolic() as well as __print_flags().

      perf header: Fix possible memory leaks in process_group_desc() · 50a2740b
      Namhyung Kim 提交于
      After processing all group descriptors or encountering an error, it
      frees all descriptors.  However, current logic can leak memory since it
      might not traverse all descriptors.
      
      Note that the 'i' can have different value than nr_groups when an error
      occurred and it's safe to call free(desc[i].name) for every desc since
      we already make it NULL when it's reused for group names.

        While most of them are just build fixes, there are some fixes for real

        A few of those might be considered a security risk, if the i2c-dev

         1) there are several patch series ready, but depending on DT review.
            I decided to grant some extra time for DT maintainers to look on
            it, as they're expecting to have more time with the changes agreed
            during ARM mini-summit and KS.  If they can't review in time for
            3.14, I'll review myself and apply for the next merge window.
      
         2) I suspect that having both LinuxCon EU and LinuxCon NA happening
            during the same merge window affected the development
            productivity, as several core media developers participated on

      Pull EDAC updates from Borislav Petkov:
       "Following up on last week's discussion, here's my part of the EDAC
        pile, highlights in the signed tag.
      
        The last two patches have a date from just now because I've just
        applied them to the tree after Johannes sent them to me earlier.  I
        decided to forward them now because they're trivial.
      
        There's a third one for MPC85xx which adds PCIe error interrupt
        support but since it is not so trivial and hasn't seen any linux-next
        time, I'm deferring it to 3.14
      
        EDAC update highlights:
         - Support for Calxeda ECX-2000 memory controller, from Robert Richter
         - Misc Calxeda Highbank drivers and EDAC core cleanups, from Rob
           Herring and Robert Richter

       "MMC highlights for 3.13:
      
        Core:
         - Improve runtime PM support, remove mmc_{suspend,resume}_host().
         - Add MMC_CAP_RUNTIME_RESUME, for delaying MMC resume until we're
           outside of the resume sequence (in runtime_resume) to decrease
           system resume time.
      
        Drivers:

         - sdhci-eshdc-imx: Support SD3.0 SDR clock tuning, DDR on IMX6.

      watchdog: w83627hf: Use helper functions to access superio registers · ef0c1a6b
      Guenter Roeck 提交于
      Use helper functions named similar to other drivers to access
      superio registers.
      
      Request memory region only when needed, and use request_muxed_region().
      This lets other devices (hwmon, gpio) use the same region.

      watchdog: w83627hf: Enable watchdog device only if not already enabled · ac461103
      Guenter Roeck 提交于
      There is no need to enable the watchdog device if it is already enabled.
      Also, when enabling the watchdog device, only set the watchdog device
      enable bit and do not touch other bits; depending on the chip type,
      those bits may enable other functionality.
