nl80211: fix old station flags compatibility

2012-01-11T20:14:50Z

My patch to validate station flags broke compatibility with the old station flags setting where all flags are always set at once since it always set the mask as all possible flags which ended up being rejected later in the station add/modify code. Fix by parsing only the current flags in the old flags attribute -- new applications and new flags should use (and will now require) the new flags attribute where the mask is given by the application.

wireless: Treat IPv6 diffserv the same as IPv4 for 802.11e

Wireless will select a different hardware queue based on the top 3 bits of the diffserv field, for ipv4. Extend that queue selection mechanism to ipv6, and make the calls orthogonal. Signed-off-by: Dave TÃ¤ht Signed-off-by: John W. Linville

cfg80211: relicense reg.c reg.h and genregdb.awk to ISC

2012-01-04T19:30:41Z

Following the tradition we have had with ath5k, ath9k, CRDA, wireless-regdb I'd like to license this code under the permissive ISC license for the code sharing purposes with other OSes, it'd sure be nice to help the landscape in this area. Although I am %82.89 owner of the regulatory code I have asked every contributor to the regulatory code and have receieved positive Acked-bys from everyone except two deceased entities: o Frans Pop RIP 2010 [0] - Frans Pop - Frans Pop o Nokia RIP February, 11, 2011 [1], [2] - ext-yuri.ershov@nokia.com - kalle.valo@nokia.com Frans Pop's contribution was a simple patch 55f98938, titled, "wireless: remove trailing space in messages" which just add a \n to some printk lines. I'm going to treat these additions as uncopyrightable. As for the contributions made by employees on behalf of Nokia my contact point was Petri Karhula but after one month he noted he had not been able to get traction from the legal department on this request, as such it I proceeded by replacing their contributions in previous patches. The end goal is to help a clean rewrite that starts in userspace that is shared under ISC license which currently is taking place with the regulatory simulator [3].

cfg80211: replace reg.c Nokia commit 269ac5

2012-01-04T19:30:40Z

Nokia hasn't gotten back to me in over 1 month for a relicense change request. There are only a few changes that they contributed, so just reverting their changes but replacing with another set.

cfg80211: Restore orig channel values upon disconnect

2011-12-16T14:30:43Z

When we restore regulatory settings the world regulatory domain is properly reset on cfg80211 (or user prefered regulatory domain) but we were never setting back channel values for drivers that use WIPHY_FLAG_CUSTOM_REGULATORY. Set these values up again by using the orig_ channel parameters. This fixes restoring custom regulatory settings upon disconnect events.

cfg80211: allow following country IE power for custom regdom cards

2011-12-16T14:30:42Z

By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the wiphy to adjust itself to the country IE power information if the card had no regulatory data but we had no way to tell cfg80211 that if the card also had its own custom regulatory domain (these are typically custom world regulatory domains) that we want to follow the country IE's noted values for power for each channel. We add support for this and document it. This is not a critical fix but a performance optimization for cards with custom regulatory domains that associate to an AP with sends out country IEs with a higher EIRP than the one on the custom regulatory domain. In practice the only driver affected right now are the Atheros drivers as they are the only drivers using both WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY -- used on cards that have an Atheros world regulatory domain. Cards that have been programmed to follow a country specifically will not follow the country IE power. So although not a stable fix distributions should consider cherry picking this.

cfg80211: validate nl80211 station handling better

2011-12-15T19:45:45Z

The nl80211 station handling code is a bit messy and doesn't do a lot of validation. It seems like this could be an issue for drivers that don't use mac80211 to validate everything. As cfg80211 doesn't keep station state, move the validation of allowing supported_rates to change for TDLS only in station mode to mac80211. Signed-off-by: Johannes Berg Signed-off-by: John W.
