      [module] Don't let gcc inline load_module() · ffb4ba76
      Linus Torvalds authored
      
      
      'load_module()' is a complex function that contains all the ELF section
      logic, and inlining it is utterly insane.  But gcc will do it, simply
      because there is only one call-site.  As a result, all the stack space
      that is allocated for all the work to load the module will still be
      active when we actually call the module init sequence, and the deep call
      chain makes stack overflows happen.
      
      And stack overflows are really hard to debug, because they not only
      corrupt random pages below the stack, but also corrupt the thread_info
      structure that is allocated under the stack.
      
      In this case, Alan Brunelle reported some crazy oopses at bootup, after
      loading the processor module that ends up doing complex ACPI stuff and
      has quite a deep callchain.  This should fix it, and is the sane thing
      to do regardless.

      ipv6: protocol for address routes · f410a1fb
      Stephen Hemminger authored
      
      
      This fixes a problem spotted with zebra, but not sure if it is
      necessary a kernel problem.  With IPV6 when an address is added to an
      interface, Zebra creates a duplicate RIB entry, one as a connected
      route, and other as a kernel route.
      
      When an address is added to an interface the RTN_NEWADDR message
      causes Zebra to create a connected route. In IPV4 when an address is
      added to an interface a RTN_NEWROUTE message is set to user space with
      the protocol RTPROT_KERNEL. Zebra ignores these messages, because it
      already has the connected route.
      
      The problem is that route created in IPV6 has route protocol ==
      RTPROT_BOOT.  Was this a design decision or a bug? This fixes it. Same
      patch applies to both net-2.6 and stable.

      Pass namespace into icmp_xmit_lock, obtain socket inside and return
      it as a result for caller.
