* netfilter: xtables: use memcmp in unconditional checkJan Engelhardt2009-08-10
| | | | | | | | | Instead of inspecting each u32/char open-coded, clean up and make use of memcmp. On some arches, memcmp is implemented as assembly or GCC's __builtin_memcmp which can possibly take advantages of known alignment. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* net: Avoid enqueuing skb for default qdiscsKrishna Kumar2009-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_queue_xmit enqueue's a skb and calls qdisc_run which dequeue's the skb and xmits it. In most cases, the skb that is enqueue'd is the same one that is dequeue'd (unless the queue gets stopped or multiple cpu's write to the same queue and ends in a race with qdisc_run). For default qdiscs, we can remove the redundant enqueue/dequeue and simply xmit the skb since the default qdisc is work-conserving. The patch uses a new flag - TCQ_F_CAN_BYPASS to identify the default fast queue. The controversial part of the patch is incrementing qlen when a skb is requeued - this is to avoid checks like the second line below: + } else if ((q->flags & TCQ_F_CAN_BYPASS) && !qdisc_qlen(q) && >> !q->gso_skb && + !test_and_set_bit(__QDISC_STATE_RUNNING, &q->state)) { Results of a 2 hour testing for multiple netperf sessions (1, 2, 4, 8, 12 sessions on a 4 cpu system-X).

| * mac80211: FIF_PSPOLL filter flagIgor Perminov2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an interface is configured in the AP mode, the mac80211 implementation doesn't inform the driver to receive PS Poll frames. It leads to inability to communicate with power-saving stations reliably. The FIF_CONTROL flag isn't passed by mac80211 to ieee80211_ops.configure_filter when an interface is in the AP mode. And it's ok, because we don't want to receive ACK frames and other control ones, but only PS Poll ones. This patch introduces the FIF_PSPOLL filter flag in addition to FIF_CONTROL, which means for the driver "pass PS Poll frames". This flag is passed to the driver: A) When an interface is configured in the AP mode. B) In all cases, when the FIF_CONTROL flag was passed earlier (in addition to it).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If hw initialization fails (ath9k_hw_init()) on ath_init_softc() we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach() is conditional though as ath9k_hw_init() could itself have called ath9k_hw_detach(). Just describing this is itself a brain twister. Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init(). Upon hw initialization failure we expect the callers to take care of the cleanup. Signed-off-by: Luis R.
