In bond_alb and bond_main, we check all positive increment for promiscuity
and allmulti to get error return.
But there are still two problems left.
1. Some code path has no mechanism to signal errors upstream.
2. If there are multi slaves, it's hard to tell which slaves increment
   promisc/allmulti successfully and which failed.
So I left these problems to be FIXME.
Fortunately, the overflow is very rare case.

mac80211: make master netdev handling sane

Currently, almost every interface type has a 'bss' pointer
pointing to BSS information. This BSS information, however,
is for a _local_ BSS, not for the BSS we joined, so having
it on a STA mode interface makes little sense, but now they
have it pointing to the master device, which is an AP mode
virtual interface. However, except for some bitrate control
data, this pointer is only used in AP/VLAN modes (for power
saving stations.)

Overall, it is not necessary to even have the master netdev
be a valid virtual interface, and it doesn't have to be on
the list of interfaces either.

rt2x00: Fix NULL pointer error in adhoc/master mode

As soon as an interface is enabled, and that interface is in adhoc or master mode,
the device will start raising beacondone interrupts. But before the first interrupt is
raised, mac80211 will probably not have send any beacons to the device yet, which
results in a NULL pointer error when the skb is being freed.

Note that the "raise beacondone interrupts without a beacon" is also a bug,
and will be addressed later. The more important bug however is preventing

TX queue gets full and driver does netif_stop_queue().
App closes fd and TX queue gets flushed as part of the cleanup.
Next time the app opens tun/tap and starts reading from it but
the xoff state is not cleared. We're stuck.

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.
