      Input: i8042 - fix crash at boot time · 340d394a
      Chen Hong authored
      The driver checks port->exists twice in i8042_interrupt(), first when
      trying to assign temporary "serio" variable, and second time when deciding
      whether it should call serio_interrupt(). The value of port->exists may
      change between the 2 checks, and we may end up calling serio_interrupt()
      with a NULL pointer:

      To avoid the issue let's change the second check to test whether serio is
      NULL or not.
      
      Also, let's take i8042_lock in i8042_start() and i8042_stop() instead of
      trying to be overly smart and using memory barriers.

      ftrace use module_alloc() to allocate trampoline pages. The mapping of
      module_alloc() is RWX, which makes sense as the memory is written to right
      after allocation. But nothing makes these pages RO after writing to them.
      
      Add proper set_memory_rw/ro() calls to protect the trampolines after
      modification.

      x86/mm/ftrace: Do not bug in early boot on irqs_disabled in cpu_flush_range() · a53276e2

      With function tracing starting in early bootup and having its trampoline
      pages being read only, a bug triggered with the following:

      Interrupts should not be enabled at this early in the boot process. It is
      also fine to leave interrupts enabled during this time as there's only one
      CPU running, and on_each_cpu() means to only run on the current CPU.
      
      If early_boot_irqs_disabled is set, it is safe to run cpu_flush_range() with
      interrupts disabled. Don't trigger a BUG_ON() in that case.

      selftests/ftrace: Add a testcase for many kprobe events · bdd7e3d6
      Masami Hiramatsu authored
      Add a testcase to test kprobes via ftrace interface
      with many concurrent kprobe events.
      
      This tries to add many kprobe events (up to 256) on
      kernel functions. To avoid making ftrace-based
      kprobes (kprobes on fentry), it skips first N bytes
      (on x86 N=5, on ppc or arm N=4) of function entry.
      After that, it enables all those events, disable it,
      and remove it.
      
      Since the unoptimization buffer reclaiming will
      be delayed, after removing events, it will wait
      enough time.

      kprobes/x86: Fix to set RWX bits correctly before releasing trampoline · c93f5cf5
      Masami Hiramatsu authored
      Fix kprobes to set(recover) RWX bits correctly on trampoline
      buffer before releasing it. Releasing readonly page to
      module_memfree() crash the kernel.
      
      Without this fix, if kprobes user register a bunch of kprobes
      in function body (since kprobes on function entry usually
      use ftrace) and unregister it, kernel hits a BUG and crash.

      ftrace: Fix memory leak in ftrace_graph_release() · f9797c2f
      Luis Henriques authored
      ftrace_hash is being kfree'ed in ftrace_graph_release(), however the
      ->buckets field is not.  This results in a memory leak that is easily
      captured by kmemleak:
