As discussed we do not know band width at core reset time and it is not a good idea to reset whole just to change band. So just set unconditionally 20 MHz band width as default during core reset. As for defines PHY clock changed to band width in specs and it makes much more sens to call defines by band width which is self-explainable. Updated specs do not mention 0 value, but comparing to old ones you can notice lineral relation between PHY clock speed and band width. So it makes sense for 0x0 value to be 10 MHz band width.

Allow userspace to specify that a given key is default only for unicast and/or multicast transmissions. Only WEP keys are for both, WPA/RSN keys set here are GTKs for multicast only. For more future flexibility, allow to specify all combiations. Wireless extensions can only set both so use nl80211; WEP keys (connect keys) must be set as default for both (but 802.1X WEP is still possible). Signed-off-by:

Using the default key for "any key set" isn't quite what we should do. It works, but with the upcoming changes it makes life unnecessarily complex, so do something better here and really check for "any key". Signed-off-by:

The registers TBTT_TIMER ,DMA_BEACON_ALERT ,NEXT_SWBA are need to be configured only for AP and IBSS mode. SWBA register is used for generating software interrupts so that beacon frames will be created by the software.DMA beacon alert register is to indicate the hardware to DMA the contents of beacon buffer to PCU buffer and TBTT to start transmitting the packet buffer to the base band. Clearly these things are not needed for station/monitor mode so remove configuring them. Cc: doug dahlby <ddahlby@atheros.com> Signed-off-by:

When a cached BSS struct is updated because a new beacon was received, the code replaces the cached information elements by the IEs from the new beacon. However it did not update the pub.information_elements and pub.len_information_elements fields leaving them either pointing to the old beacon IEs or in an inconsistent state where the data is replaced by the new beacon IEs but len_information_elements still has its value from the first beacon. Fix this by updating the information elements fields if they are pointing to beacon IEs. Signed-off-by:

Add a field to wiphy for the hardware to report the availble antennas for configuration. Only if this is set to something bigger than zero, will the anntenna configuration ops be executed. Allthough this could be a simple number of antennas, I defined it as a bitmap of antennas which are available for configuration, since it's more consistent with the rest of the antenna API and there could be cases where the hardware allows only configuration of certain antennas. As it does not make much of a difference in size or normal usage, I think it's better to be able to support this, in case the need arises. The antenna configuration is now also checked against the availabe antennas and rejected if it does not match. Signed-off-by:

mac80211 will notify drivers when to go idle and ath9k assumed that it would get further notifications for idle states after a device stop() config call but as per agreed semantics the idle state of the radio is left up to driver after mac80211 issues the stop() callback. The driver is resposnbile for ensuring the device remains idle after that even between suspend / resume calls. This fixes suspend/resume when you issue suspend and resume twice on ath9k when ath9k_stop() was already called. We need to put the radio to full sleep in order for resume to work correctly. What might seem fishy is we are turning the radio off after resume. The reason why we do this is because we know we should not have anything enabled after a mac80211 tells us to stop(), if we resume and never get a start() we won't get another stop() by mac80211 so to be safe always bring the 802.11 device with the radio disabled after resume, this ensures that if we suspend we already have the radio disabled and only a start() will ever trigger it on.

Upon a failure we never call ath9k_ps_restore() on ath_radio_enable(), this will throw off the sc->ps_usecount. When the sc->ps_usecount is > 0 we never put the chip to full sleep. This drains battery, and will also make the chip fail upon resume with: ath: Starting driver with initial channel: 5745 MHz ath: timeout (100000 us) on reg 0x7000: 0xdeadbeef & 0x00000003 != 0x00000000 This would make the chip useless upon resume. I cannot prove this can happen but in theory it is so best to avoid this race completely and not have users complain about a broken device after resume.

Enable the port when disabling countermeasures, and disable it on enabling countermeasures. This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

... and interface up. In these situations, you are usually trying to connect to a new AP, so keeping TKIP countermeasures active is confusing. This is already how the driver behaves (inadvertently). However, querying SIOCGIWAUTH may tell userspace that countermeasures are active when they aren't. Clear the setting so that the reporting matches what the driver has done..

To avoid copying the skb unnecessarily move the skb_copy call below the checks that don't need write access to the skb. Also, move the assignment of nh_pos and h_pos below the skb_copy to point to the correct skb. It would be possible to avoid another resize of the copied skb by using skb_copy_expand instead of skb_copy but that would make the patch more complex. Also, shared skbs are a corner case right now, so the resize shouldn't matter much. Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by:
