      x86: i386-show-unhandled-signals-v3 · abd4f750
      Masoud Asgharifard Sharbiani 提交于
      This patch makes the i386 behave the same way that x86_64 does when a
      segfault happens.  A line gets printed to the kernel log so that tools
      that need to check for failures can behave more uniformly between
      debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 >
      /proc/sys/debug/exception-trace)
      
      Also, all of the lines being printed are now using printk_ratelimit() to
      deny the ability of DoS from a local user with a program like the
      following:
      
      main()
      {
             while (1)
                     if (!fork()) *(int *)0 = 0;
      }
      
      This new revision also includes the fix that Andrew did which got rid of
      new sysctl that was added to the system in earlier versions of this.
      Also, 'show-unhandled-signals' sysctl has been renamed back to the old
      'exception-trace' to avoid breakage of people's scripts.
      
      AK: Enabling by default for i386 will be likely controversal, but let's see what happens
      AK: Really folks, before complaining just fix your segfaults
      AK: I bet this will find a lot of silent issues

      [ Personally, I've found the complaints useful on x86-64, so I'm all for
        this. That said, I wonder if we could do it more prettily..   -Linus ]

      [PATCH] x86-64: fix section mismatch warnings · 43999d9e

      Fix the following section mismatch warnings on x86_64:

      But adds:

      The warnings does not show up during a normal build due to kbuild
      failing to check for section mismatch in vmlinux.
      To see these warnings run:
      scripts/mod/modpost arch/x86_64/kernel/built-in.o
      
      kbuild will be fixed but the 'noise-level' had to be decresed first.
      There remains a few section mismatch warnigns for x86_64 for areas where I did
      not feel confident.
