2011-03-14tcp_cubic: fix low utilization of CUBIC with HyStartSangtae Ha
HyStart sets the initial exit point of slow start. Suppose that HyStart exits at 0.5BDP in a BDP network and no history exists. If the BDP of a network is large, CUBIC's initial cwnd growth may be too conservative to utilize the link. CUBIC increases the cwnd 20% per RTT in this case.

2011-03-14tcp_cubic: fix comparison of jiffiesstephen hemminger
Jiffies wraps around therefore the correct way to compare is to use cast to signed value.

2011-03-14tcp: fix RTT for quick packets in congestion controlstephen hemminger
In the congestion control interface, the callback for each ACK includes an estimated round trip time in microseconds. Some algorithms need high resolution (Vegas style) but most only need jiffie resolution. If RTT is not accurate (like a retransmission) -1 is used as a flag value. When doing coarse resolution if RTT is less than a a jiffie then 0 should be returned rather than no estimate. Otherwise algorithms that expect good ack's to trigger slow start (like CUBIC Hystart) will be confused. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2011-03-14bridge: skip forwarding delay if not using STPstephen hemminger
If Spanning Tree Protocol is not enabled, there is no good reason for the bridge code to wait for the forwarding delay period before enabling the link. The purpose of the forwarding delay is to allow STP to learn about other bridges before nominating itself. The only possible impact is that when starting up a new port the bridge may flood a packet now, where previously it might have seen traffic from the other host and preseeded the forwarding table. Includes change for local variable br already available in that func. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-14bridge: control carrier based on ports onlinestephen hemminger
This makes the bridge device behave like a physical device. In earlier releases the bridge always asserted carrier. This changes the behavior so that bridge device carrier is on only if one or more ports are in the forwarding state. This should help IPv6 autoconfiguration, DHCP, and routing daemons. I did brief testing with Network and Virt manager and they seem fine, but since this changes behavior of bridge, it should wait until net-next (2.6.39).

2011-03-14mac80211: fix channel type recalculation with HT and non-HT interfacesFelix Fietkau
When running an AP interface along with the cooked monitor interface created by hostapd, adding an interface and deleting it again triggers a channel type recalculation during which the (non-HT) monitor interface takes precedence over the HT AP interface, thus causing the channel type to be set to non-HT.

2011-03-14ath9k: improve reliability of beacon transmission and stuck beacon handlingFelix Fietkau
ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there is not much point in doing that if the previous beacon and mcast traffic went out properly. On AR9380, calling that function too often can result in an increase of stuck beacons due to differences in the handling of the queue enable/disable functionality. With this patch, the queue will only be explicitly stopped if the previous data frames were not sent successfully. With the beacon code being the only remaining user of ath9k_hw_stoptxdma, this function can be simplified in order to remove the now pointless attempts at waiting for transmission completion, which would never happen at this point due to the different method of tx scheduling of the beacon queue.

In some situations, stopping Tx DMA frequently fails, leading to messages like this: ath: Failed to stop TX DMA in 100 msec after killing last frame ath: Failed to stop TX DMA! This patch uses a few MAC features to abort DMA globally instead of iterating over all hardware queues and attempting to stop them individually. Not only is that faster and works with a shorter timeout, it also makes the process much more reliable. With this change, I can no longer trigger these messages on AR9380, and on AR9280 they become much more rare. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-03-14xfrm: Support anti-replay window size bigger than 32 packetsSteffen Klassert
As it is, the anti-replay bitmap in struct xfrm_replay_state can only accomodate 32 packets. Even though it is possible to configure anti-replay window sizes up to 255 packets from userspace. So we reject any packet with a sequence number within the configured window but outside the bitmap. With this patch, we represent the anti-replay window as a bitmap of variable length that can be accessed via the new struct xfrm_replay_state_esn. Thus, we have no limit on the window size anymore. To use the new anti-replay window implementantion, new userspace tools are required. We leave the old implementation untouched to stay in sync with old userspace tools.
