2014-07-21wireless: fixup genregdb.awk for remove of antenna gain from wireless-regdLuis R. Rodriguez
Since "wireless-regdb: remove antenna gain" was merged in the wireless-regdb tree, the awk script parser has been incompatible with the 'official' regulatory database. This fixes that up. Without this change the max EIRP is set to 0 making 802.11 devices useless. The fragile nature of the awk parser must be replaced, but ideas over how to do that in the most scalable way are being reviewed. In the meantime update the documentation for CFG80211_INTERNAL_REGDB so folks are aware of expectations for now.

2014-05-27regdb: Generalize the mW to dBm power conversionchaitanya.mgit@gmail.com
Generalize the power conversion from mW to dBm using log. This should fix the below compilation error for country NO which adds a new power value 2000mW which is not handled earlier.

2014-02-25cfg80211: regulatory: allow getting DFS CAC time from userspaceJanusz Dziedzic
Introduce DFS CAC time as a regd param, configured per REG_RULE and set per channel in cfg80211. DFS CAC time is close connected with regulatory database configuration. Instead of using hardcoded values, get DFS CAC time form regulatory database. Pass DFS CAC time to user mode (mainly for iw reg get, iw list, iw info). Allow setting DFS CAC time via CRDA. Add support for internal regulatory database. Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> [rewrap commit log] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-02-21cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flagJanusz Dziedzic
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set maximum available bandwidth should be calculated base on contiguous rules and wider channels will be allowed to cross multiple contiguous/overlapping frequency ranges. In case of old kernels maximum bandwidth from regulatory rule will be used, while there is no NL80211_RRF_AUTO_BW flag. This fixes the previous commit 9752482083066af7ac18a5ca376f ("cfg80211: regulatory introduce maximum bandwidth calculation") which was found to be a problem for userspace API compatibility.

2013-11-25cfg80211: consolidate passive-scan and no-ibss flagsLuis R. Rodriguez
These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels. Update all places in the tree using these flags with the following semantic patch: @@ @@ -NL80211_RRF_PASSIVE_SCAN +NL80211_RRF_NO_IR @@ @@ -NL80211_RRF_NO_IBSS +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_PASSIVE_SCAN +IEEE80211_CHAN_NO_IR @@ @@ -IEEE80211_CHAN_NO_IBSS +IEEE80211_CHAN_NO_IR @@ @@ -NL80211_RRF_NO_IR | NL80211_RRF_NO_IR +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_NO_IR | IEEE80211_CHAN_NO_IR +IEEE80211_CHAN_NO_IR @@ @@ -(NL80211_RRF_NO_IR) +NL80211_RRF_NO_IR @@ @@ -(IEEE80211_CHAN_NO_IR) +IEEE80211_CHAN_NO_IR Along with some hand-optimisations in documentation, to remove duplicates and to fix some indentation.

2012-01-04cfg80211: relicense reg.c reg.h and genregdb.awk to ISCLuis R. Rodriguez
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 <elendil@planet.nl> - Frans Pop <fjp@debian.org> 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 <petri.karhula@nokia.com> 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].

2009-12-21wireless: support internal statically compiled regulatory databaseJohn W. Linville
This patch provides infrastructure for machine translation of the regulatory rules database used by CRDA into a C data structure. It includes code for searching that database as an alternative to dynamic regulatory rules updates via CRDA. Most people should use CRDA instead of this infrastructure, but it provides a better alternative than the WIRELESS_OLD_REGULATORY infrastructure (which can now be removed). Signed-off-by: John W.
