2011-03-15ipvs: properly zero stats and ratesJulian Anastasov
Currently, the new percpu counters are not zeroed and the zero commands do not work as expected, we still show the old sum of percpu values. OTOH, we can not reset the percpu counters from user context without causing the incrementing to use old and bogus values. So, as Eric Dumazet suggested fix that by moving all overhead to stats reading in user context. Do not introduce overhead in timer context (estimator) and incrementing (packet handling in softirqs). The new ustats0 field holds the zero point for all counter values, the rates always use 0 as base value as before. When showing the values to user space just give the difference between counters and the base values. The only drawback is that percpu stats are not zeroed, they are accessible only from /proc and are new interface, so it should not be a compatibility problem as long as the sum stats are correct after zeroing.

2011-03-15ipvs: reorganize tot_statsJulian Anastasov
The global tot_stats contains cpustats field just like the stats for dest and svc, so better use it to simplify the usage in estimation_timer. As tot_stats is registered as estimator we can remove the special ip_vs_read_cpu_stats call for tot_stats. Fix ip_vs_read_cpu_stats to be called under stats lock because it is still used as synchronization between estimation timer and user context (the stats readers). Also, make sure ip_vs_stats_percpu_show reads properly the u64 stats from user context.

HyStart sets the initial exit point of slow start. Suppose that HyStart exits at 0.5BDP in a BDP network and no history exists.

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.

2011-03-13xfrm: 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.

Previously, the bit was set only if there were at least 2 working links to the peer node, meaning the bit was incorrectly left unset in messages sent by a non-working link endpoint when exactly one alternate working link was available.
