2010-02-19iwlwifi: enable serialization of synchronous commandsReinette Chatre
Until now it was only possible to have one synchronous command running at any time. If a synchronous command is in progress when a second request arrives then the second command will fail. Create a new mutex specific for this purpose to only allow one synchronous command at a time, but enable other commands to wait instead of fail if a synchronous command is in progress.

This also removes a potential confusing definition with iwlcore using STATUS_MODE_PENDING with value 18 and iwl3945 defining (but not using) STATUS_CONF_PENDING for value 18.

2010-02-19ath9k: fix rate control fallback rate selectionFelix Fietkau
When selecting the tx fallback rate, rc.c used a separate variable 'nrix' for storing the next rate index, however it did not use that as reference for further rate index lowering. Because of that, it ended up reusing the same rate for multiple multi-rate retry stages, thus decreasing delivery probability under changing link conditions. This patch removes the separate (unnecessary) variable and fixes fallback the way it was intended to work. This should result in increased throughput and better link stability.

2010-02-19nl80211: add power save commandsKalle Valo
The most needed command from nl80211, which Wireless Extensions had, is support for power save mode. Add a simple command to make it possible to enable and disable power save via nl80211. I was also planning about extending the interface, for example adding the timeout value, but after thinking more about this I decided not to do it. Basically there were three reasons: Firstly, the parameters for power save are very much hardware dependent. Trying to find a unified interface which would work with all hardware, and still make sense to users, will be very difficult. Secondly, IEEE 802.11 power save implementation in Linux is still in state of flux. We have a long way to still to go and there is no way to predict what kind of implementation we will have after few years. And because we need to support nl80211 interface a long time, practically forever, adding now parameters to nl80211 might create maintenance problems later on. Third issue are the users. Power save parameters are mostly used for debugging, so debugfs is better, more flexible, interface for this. For example, wpa_supplicant currently doesn't configure anything related to power save mode. It's better to strive that kernel can automatically optimise the power save parameters, like with help of pm qos network and other traffic parameters. Later on, when we have better understanding of power save, we can extend this command with more features, if there's a need for that.

2010-02-19iwlwifi: set HT flags after channel in rxonDan Halperin
The HT extension channel settings require priv->staging_rxon.channel to be accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel and thus HT40 could be broken unless another call to iwl_mac_config came in. This problem was recently introduced by "iwlwifi: Fix to set correct ht configuration" The particular setting in which I noticed this was monitor mode: iwconfig wlan0 mode monitor ifconfig wlan0 up ./iw wlan0 set channel 64 HT40- #./iw wlan0 set channel 64 HT40- tcpdump -i wlan0 -y IEEE802_11_RADIO would only catch HT40 packets if I issued the IW command twice. From visual inspection, iwl_set_rxon_channel does not depend on iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.

2010-02-19hw-breakpoint: Keep track of dr7 local enable bitsFrederic Weisbecker
When the user enables breakpoints through dr7, he can choose between "local" or "global" enable bits but given how linux is implemented, both have the same effect. That said we don't keep track how the user enabled the breakpoints so when the user requests the dr7 value, we only translate the "enabled" status using the global enabled bits. It means that if the user enabled a breakpoint using the local enabled bit, reading back dr7 will set the global bit and clear the local one. Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated softwares that implement old reverse engineering protection schemes. We fix that by keeping track of the whole dr7 value given by the user in the thread structure to drop this bug. We'll think about something more proper later. This fixes a 2.6.32 - 2.6.33-x ptrace regression.

single fragment When an ICMPV6_PKT_TOOBIG message is received with a MTU below 1280, all further packets include a fragment header. Unlike regular defragmentation, conntrack also needs to "reassemble" those fragments in order to obtain a packet without the fragment header for connection tracking. Currently nf_conntrack_reasm checks whether a fragment has either IP6_MF set or an offset != 0, which makes it ignore those fragments.
