2008-07-08netdev: Move rest of qdisc state into struct netdev_queueDavid S. Miller
Now qdisc, qdisc_sleeping, and qdisc_list also live there. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: The ingress_lock member is no longer needed.David S. Miller
Every qdisc is assosciated with a queue, and in the case of ingress qdiscs that will now be netdev->rx_queue so using that queue's lock is the thing to do. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move queue_lock into struct netdev_queue.David S. Miller
The lock is now an attribute of the device queue. One thing to notice is that "suspicious" places emerge which will need specific training about multiple queue handling. They are so marked with explicit "netdev->rx_queue" and "netdev->tx_queue" references. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Remove 'dev' member of struct Qdisc.David S. Miller
It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Create netdev_queue abstraction.David S. Miller
A netdev_queue is an entity managed by a qdisc. Currently there is one RX and one TX queue, and a netdev_queue merely contains a backpointer to the net_device. The Qdisc struct is augmented with a netdev_queue pointer as well. Eventually the 'dev' Qdisc member will go away and we will have the resulting hierarchy: net_device --> netdev_queue --> Qdisc Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue pointer argument.

2008-07-08vlan: avoid header copying and linearisation where possiblePatrick McHardy
- vlan_dev_reorder_header() is only called on the receive path after calling skb_share_check(). This means we can use skb_cow() since all we need is a writable header. - vlan_dev_hard_header() includes a work-around for some apparently broken out of tree MPLS code. The hard_header functions can expect to always have a headroom of at least there own hard_header_len available, so the reallocation check is unnecessary. - __vlan_put_tag() can use skb_cow_head() to avoid the skb_unshare() copy when the header is writable.

2008-07-08ipv6: fix race between ipv6_del_addr and DAD timerAndrey Vagin
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.

2008-07-08net/wireless/nl80211.c: fix endless Netlink callback loop.Julius Volz
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.

2008-07-08rfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switchHenrique de Moraes Holschuh
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.
