2008-03-25mac80211: configure default wmm params correctlyVladimir Koutny
Default WMM params have to be set according to beacon/probe response information prior to authentication (or IBSS start/join); beacon queue is configured only in IBSS. This does not affect the use of 'real' WMM params as reported by AP. Signed-off-by: Vladimir Koutny <vlado@ksp.sk> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-03-25mac80211: prevent tuning during scanningMohamed Abbas
Postpone calling ieee80211_hw_config if hardware scanning is active. This is similar to solution for software scanning where channel setting is delayed until scan complete.

2008-03-25mac80211: filter scan results on unusable channelsJohannes Berg
When you have an AP on channel 13, it will currently often enough be listed in scan results even when the regulatory domain restricts to channels 1-11. This is due to channel overlap. To avoid getting very strange failures, don't show such APs in the scan results. The failure mode will now go from "I can see the AP but not associate" to "I can't see the AP although I know it's there" which is easier to debug. This problem was first really noticed by Jes Sorensen. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: Jes Sorensen <jes@trained-monkey.org> Signed-off-by: John W.

2008-03-25mac80211: allows driver to request a Phase 1 RX keyEmmanuel Grumbach
This patch makes mac80211 able to send a phase1 key for TKIP decryption. This is needed for drivers that don't do the rekeying by themselves (i.e. iwlwifi). Upon IV16 wrap around, the packet is decrypted in SW, if decryption is ok, mac80211 calls to update_tkip_key with a new phase 1 RX key.

2008-03-25mac80211: get a TKIP phase key from skbEmmanuel Grumbach
This patch makes mac80211 able to compute a TKIP key from an skb. The requested key can be a phase 1 or a phase 2 key.

2008-03-25[XFRM] MIP6: Fix address keys for routing search.YOSHIFUJI Hideaki
Each MIPv6 XFRM state (DSTOPT/RH2) holds either destination or source address to be mangled in the IPv6 header (that is "CoA"). On Inter-MN communication after both nodes binds each other, they use route optimized traffic two MIPv6 states applied, and both source and destination address in the IPv6 header are replaced by the states respectively. The packet format is correct, however, next-hop routing search are not. This patch fixes it by remembering address pairs for later states.

2008-03-23sch_htb: fix "too many events" situationMartin Devera
HTB is event driven algorithm and part of its work is to apply scheduled events at proper times. It tried to defend itself from livelock by processing only limited number of events per dequeue. Because of faster computers some users already hit this hardcoded limit. This patch limits processing up to 2 jiffies (why not 1 jiffie ? because it might stop prematurely when only fraction of jiffie remains).
