* net: convert BUG_TRAP to generic WARN_ONIlpo Järvinen2008-07-256-26/+25
| | | | | | | | | | | | | | Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future. I could make at least one BUILD_BUG_ON conversion. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | In the merge phase of the CAN subsystem the af_family_clock_key_strings[] have been added to sock.c in commit 443aef0eddfa44c158d1b94ebb431a70638fcab4 (lockdep: fixup sk_callback_lock annotation).

* netdev: Remove warning from __netif_schedule().David S. Miller2008-07-231-3/+0
| | | | | | | | | | | It isn't helping anything and we aren't going to be able to change all the drivers that do queue wakeups in strange situations. Just letting a noop_qdisc get scheduled will work because when qdisc_run() executes via net_tx_work() it will simply find no packets pending when it makes the ->dequeue() call in qdisc_restart.

* pkt_sched: Manage qdisc list inside of root qdisc.David S. Miller2008-07-181-2/+0
| | | | | | | | | | | | | | | | | Idea is from Patrick McHardy. Instead of managing the list of qdiscs on the device level, manage it in the root qdisc of a netdev_queue. This solves all kinds of visibility issues during qdisc destruction. The way to iterate over all qdiscs of a netdev_queue is to visit the netdev_queue->qdisc, and then traverse it's list. The only special case is to ignore builting qdiscs at the root when dumping or doing a qdisc_lookup(). That was not needed previously because builtin qdiscs were not added to the device's qdisc_list.

Therefore it doesn't make any sense to schedule the transmit queue when logically we cannot know ahead of time the TX queue of the SKB that the qdisc->dequeue() will give us. Just for sanity I added a BUG check to make sure we never get into a state where the noop_qdisc is scheduled. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | | | netdev: Add netdev->select_queue() method.David S. Miller2008-07-171-3/+6

This function runs under RCU protection, which allows overriding functions to have some way of synchronizing with things like dynamic ->real_num_tx_queues adjustments. This makes the spinlock prefetch in dev_queue_xmit() a little bit less effective, but that's the price right now for correctness. Signed-off-by: David S. Miller <davem@davemloft.net>

Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

* | | | | netdev: Allocate multiple queues for TX.David S. Miller2008-07-172-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

If that queue exceeds its set length, it will drop an skb on the queue to enqueue the newly arrived skb. This results in a drop for which we have no statistics incremented.

* | | | | netdev: Kill qdisc_ingress, use netdev->rx_queue.qdisc instead.David S. Miller2008-07-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that our qdisc management is bi-directional, per-queue, and fully orthogonal, there is no reason to have a special ingress qdisc pointer in struct net_device. Signed-off-by: David S. Miller <davem@davemloft.net>
* | | | | netdev: Move rest of qdisc state into struct netdev_queueDavid S. Miller2008-07-083-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now qdisc, qdisc_sleeping, and qdisc_list also live there. Signed-off-by: David S. Miller <davem@davemloft.net>
* | | | | netdev: The ingress_lock member is no longer needed.David S. Miller2008-07-081-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | | | | netdev: Move queue_lock into struct netdev_queue.David S. Miller2008-07-081-11/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | | | | netdev: Create netdev_queue abstraction.David S. Miller2008-07-081-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
