That is because of the CONFIG_WIRELESS_OLD_REGULATORY=y which I keep insisting should die already.

Correct. With OLD_REG it also means you'll get a static default "US" regulatory domain. The only other two static options are "JP" and "EU". This is why this is OLD_REG -- its using static definitions and the information is present inside the kernel. Because you _may_ still have CRDA installed we also call CRDA if your ieee80211_regdomain module parameter is either "US" or "JP" because there are actual valid ISO / IEC 3166 alpha2 country codes and if CRDA is present you will get to reap the benefits of an updated regulatory domain. > Neither seems to > happen On what device? Keep in mind iwlfifi driver ignores the first regulatory setting by the regulatory code. If users later want to enhance regulatory further they will have to call it manually using iw: iw reg set FR > so is it the "correct" way to do this through the > ieee80211_regdom module parameter? No, that should be used only for "US", "JP" and "EU", but technically you can also try "FR" and CRDA will be called as well if present. But the correct way to do this from userspace is to do it through iw or wpa_supplicant, which as the capability of setting it too. If you are writing your own application you can use the same nl80211 command as iw and wpa_supplicant, NL80211_CMD_REQ_SET_REG. > And I wonder how this is supposed > to happen "idiot-proof" in the future?
