  to always have a headroom of at least there own hard_header_len

ipv6: fix race between ipv6_del_addr and DAD timer

Consider the following scenario:

ipv6_del_addr(ifp)
  ipv6_ifa_notify(RTM_DELADDR, ifp)
    ip6_del_rt(ifp->rt)

after returning from the ipv6_ifa_notify and enabling BH-s
back, but *before* calling the addrconf_del_timer the
ifp->timer fires and:

addrconf_dad_timer(ifp)
  addrconf_dad_completed(ifp)
    ipv6_ifa_notify(RTM_NEWADDR, ifp)
      ip6_ins_rt(ifp->rt)

then return back to the ipv6_del_addr and:

in6_ifa_put(ifp)
  inet6_ifa_finish_destroy(ifp)
    dst_release(&ifp->rt->u.dst)

After this we have an ifp->rt inserted into fib6 lists, but
queued for gc, which in turn can result in oopses in the
fib6_run_gc. Maybe some other nasty things, but we caught
only the oops in gc so far.

The solution is to disarm the ifp->timer before flushing the
rt from it.

net/wireless/nl80211.c: fix endless Netlink callback loop.

Although I only tested similar code (I don't use any of this wireless
code), the state maintainance between Netlink dump callback invocations
seems wrong here and should lead to an endless loop. There are also other
examples in the same file which might have the same problem. Perhaps someone
can actually test this (or refute my logic).

Take the simple example with only one element in the list (which should fit
into the message):

1. invocation:
  Start:
    idx = 0, start = 0
  Loop:
    condition (++idx < start) => (1 < 0) => false
    => no continue, fill one entry, exit loop, return skb->len > 0

2. invocation:
  Start:
    idx = 0, start = 1
  Loop:
    condition (++idx < start) => (1 < 1) => false
    => no continue, fill the same entry again, exit loop, return skb->len > 0

3. invocation:
  Same as 2. invocation, endless invocation of callback.

Also, iterations where the filling of an element fails should not be counted as
completed, so idx should not be incremented in this case.

rfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switch

rfkill_add_switch() calls rfkill_toggle_radio() to set the state of a
recently registered rfkill class to the current global state [for that
rfkill->type].

The rfkill_toggle_radio() call is going to error out if the hardware is
RFKILL_STATE_HARD_BLOCKED, and the global state is RFKILL_STATE_UNBLOCKED.

That is a quite normal situation which I missed to account for.  As things
stand, the error return from rfkill_toggle_radio ends up causing
rfkill_register to bail out with an error (de-registering the new switch in
the process), which is Not Nice.

Change rfkill_add_switch() to not return errors because of a failed call to
rfkill_toggle_radio().  We can go back to returning errors again (if that's
indeed the right thing to do) if we define the exact error codes the
rfkill->toggle_radio callbacks are to return in each situation, so that we
can ignore the right ones only.
