      [PATCH] Kprobes: prevent possible race conditions generic · d0aaff97
      Prasanna S Panchamukhi authored
      There are possible race conditions if probes are placed on routines within the
      kprobes files and routines used by the kprobes.  For example if you put probe
      on get_kprobe() routines, the system can hang while inserting probes on any
      routine such as do_fork().  Because while inserting probes on do_fork(),
      register_kprobes() routine grabs the kprobes spin lock and executes
      get_kprobe() routine and to handle probe of get_kprobe(), kprobes_handler()
      gets executed and tries to grab kprobes spin lock, and spins forever.  This
      patch avoids such possible race conditions by preventing probes on routines
      within the kprobes file and routines used by kprobes.
      
      I have modified the patches as per Andi Kleen's suggestion to move kprobes
      routines and other routines used by kprobes to a seperate section
      .kprobes.text.
      
      Also moved page fault and exception handlers, general protection fault to
      .kprobes.text section.
      
      These patches have been tested on i386, x86_64 and ppc64 architectures, also
      compiled on ia64 and sparc64 architectures.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
