* [PKTGEN]: Introduce sequential flowsJamal Hadi Salim2007-07-101-8/+52
| | | | | | | | | | | By default all flows in pktgen are randomly selected. This patch introduces ability to have all defined flows to be sent sequentially.

* [CORE] Stack changes to add multiqueue hardware support APIPeter P Waskiewicz Jr2007-07-101-3/+7
| | | | | | | | | | | | | Add the multiqueue hardware device support API to the core network stack. Allow drivers to allocate multiple queues and manage them at the netdev level if they choose to do so. Added a new field to sk_buff, namely queue_mapping, for drivers to know which tx_ring to select based on OS classification of the flow.

* [NET]: cleanup extra semicolonsStephen Hemminger2007-04-251-3/+3
| | | | | | | | | | | Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals.

* [SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo2007-04-251-2/+2
| | | | | | | | | | | | | | | So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

* [NET]: Add netif_tx_lockHerbert Xu2006-06-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various drivers use xmit_lock internally to synchronise with their transmission routines. They do so without setting xmit_lock_owner. This is fine as long as netpoll is not in use. With netpoll it is possible for deadlocks to occur if xmit_lock_owner isn't set. This is because if a printk occurs while xmit_lock is held and xmit_lock_owner is not set can cause netpoll to attempt to take xmit_lock recursively. While it is possible to resolve this by getting netpoll to use trylock, it is suboptimal because netpoll's sole objective is to maximise the chance of getting the printk out on the wire. So delaying or dropping the message is to be avoided as much as possible. So the only alternative is to always set xmit_lock_owner. The following patch does this by introducing the netif_tx_lock family of functions that take care of setting/unsetting xmit_lock_owner. I renamed xmit_lock to _xmit_lock to indicate that it should not be used directly. I didn't provide irq versions of the netif_tx_lock functions since xmit_lock is meant to be a BH-disabling lock. This is pretty much a straight text substitution except for a small bug fix in winbond. It currently uses netif_stop_queue/spin_unlock_wait to stop transmission. This is unsafe as an IRQ can potentially wake up the queue. So it is safer to use netif_tx_disable. The hamradio bits used spin_lock_irq but it is unnecessary as xmit_lock must never be taken in an IRQ handler. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [NET] pktgen: Fix races between control/worker threads.Arthur Kepner2006-03-201-25/+110
| | | | | | | | | | | | | | There's a race in pktgen which can lead to a double free of a pktgen_dev's skb. If a worker thread is in the midst of doing fill_packet(), and the controlling thread gets a "stop" message, the already freed skb can be freed once again in pktgen_stop_device(). This patch gives all responsibility for cleaning up a pktgen_dev's skb to the associated worker thread.
