      [NET]: Handle disabled preemption in gfp_any() · 4498121c
      Patrick McHardy authored
      ctnetlink uses netlink_unicast from an atomic_notifier_chain
      (which is called within a RCU read side critical section)
      without holding further locks. netlink_unicast calls netlink_trim
      with the result of gfp_any() for the gfp flags, which are passed
      down to pskb_expand_header. gfp_any() only checks for softirq
      context and returns GFP_KERNEL, resulting in this warning:
      
      BUG: sleeping function called from invalid context at mm/slab.c:3032
      in_atomic():1, irqs_disabled():0
      no locks held by rmmod/7010.

      Since netlink_unicast is supposed to be callable from within RCU
      read side critical sections, make gfp_any() check for in_atomic()
      instead of in_softirq().
      
      Additionally nfnetlink_send needs to use gfp_any() as well for the
      call to netlink_broadcast).

      [NET]: Revert socket.h/stat.h ifdef hacks. · 304c209c

      This reverts 57a87bb0.
      
      As H. Peter Anvin states, this change broke klibc and it's
      not very easy to fix things up without duplicating everything
      into userspace.
      
      In the longer term we should have a better solution to this
      problem, but for now let's unbreak things.
