* mac80211: restrict to AP in outgoing interface heuristicJohannes Berg2009-02-111-0/+2
| | | | | | | | | | | | We try to find the correct outgoing interface for injected frames based on the TA, but since this is a hack for hostapd 11w, restrict the heuristic to AP mode interfaces. At some point we'll add the ability to give an interface index in radiotap or so and just remove this heuristic again.

* mac80211: implement dynamic power saveKalle Valo2008-12-195-12/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements dynamic power save for mac80211. Basically it means enabling power save mode after an idle period. Implementing it dynamically gives a good compromise of low power consumption and low latency. Some hardware have support for this in firmware, but some require the host to do it. The dynamic power save is implemented by adding an timeout to ieee80211_subif_start_xmit(). The timeout can be enabled from userspace with Wireless Extensions. For example, the command below enables the dynamic power save and sets the time timeout to 500 ms: iwconfig wlan0 power timeout 500m Power save now only works with devices which handle power save in firmware. It's also disabled by default and the heuristics when and how to enable is considered as a policy decision and will be left for the userspace to handle. In case the firmware has support for this, drivers can disable this feature with IEEE80211_HW_NO_STACK_DYNAMIC_PS. Big thanks to Johannes Berg for the help with the design and code.

| | | | | | | | | | | | | | This is a preparation for the dynamic power save support. In future there are two paths to stop the master queues and we need to track this properly to avoid starting queues incorrectly. Implement this by adding a status array for each queue.

| | | | | | | | | | | | When a STA roams back to the same AP before the previous STA entry has expired, a new STA entry is not added in mac80211. However, a Layer 2 Update frame still needs to be transmitted to update layer 2 devices about the new location for the STA.

* mac80211: Disable requests for new scans in AP modeJouni Malinen2008-12-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | AP mode operations are seriously affected if mac80211 runs through a multi-second scan while the AP is trying to send Beacon frames on the operation channel. While this could be implemented in a way that does not cause too many problems, it is not very simple and will require synchronization with Beacon frame scheduling in the drivers (scan one channel at a time between Beacon frames). Furthermore, such scanning takes quite a bit longer time and existing userspace applications would be likely to timeout while waiting for the results. For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP mode. In practice, this moves the rejection from iwl* drivers into mac80211 to make it apply to every mac80211-based driver. This issue shows up in associated stations getting disconnected when something (e.g., Network Manager) requests a scan while the interface is in AP mode. When doing this continuously (e.g., NM does it every 120 seconds), the network gets close to useless.

Concerned that whilst it was safe to assume that unalignment was the norm for the zd1211rw, and take preventative measures, it may not be the case or acceptable to use the easy fix of changing the call to memcmp(). My research however indicated that it was OK to do this, as there are a few instances where memcmp() is the preferred mechanism for doing mac address comparisons throughout the module.

* | cfg80211/mac80211: Add 802.11d supportLuis R. Rodriguez2008-11-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds country IE parsing to mac80211 and enables its usage within the new regulatory infrastructure in cfg80211. We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | Mesh interfaces are currently opened with the FIF_ALLMULTI rx filter flag set, however there is no BSSID in mesh so BSSID filtering should be disabled by setting the FIF_OTHER_BSS flag as well. Also explicitly call ieee80211_configure_filter for mesh.
