Add country option for hostapd

Keywords: hostapd, crda, country, wireless, wifi Cc:

Description

In newer Linux/compat-wireless versions, the kernel can call crda to obtain a list of allowed channels for your country. However, some application has to set this country code. "iw" can be used for that, but wpa_supplicant and hostapd also have this capability when using the nl80211 driver (available in their 0.6 branches).

I am attaching a patch to add a "country" option to the "wifi-device" configuration section. When using this option, you see the following (or similar) in dmesg after a wifi restart:

cfg80211: Calling CRDA for country: DE

cfg80211: Regulatory domain changed to country: DE

(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)

(2400000 KHz - 2483500 KHz @ 40000 KHz), (N/A, 2000 mBm)

(5150000 KHz - 5255000 KHz @ 40000 KHz), (N/A, 2301 mBm)

(5470000 KHz - 5650000 KHz @ 40000 KHz), (N/A, 3000 mBm)
