Hello! In latest regdb, there are four countries which have DFS channels but DFS region is not set: 00 (World regulatory domain) AD (Andorra) AU (Australia) HK (Hong-Kong) For example: country AU: (2402 - 2482 @ 40), (20) (5170 - 5250 @ 80), (17), AUTO-BW (5250 - 5330 @ 80), (24), DFS, AUTO-BW (5490 - 5710 @ 160), (24), DFS (5735 - 5835 @ 80), (30) However, cfg80211 has explicit check for this condition since revision 55f7435c18. Because of this, I cannot use channel 52 and above when country code is set to AU. Hostapd receives error code -EINVAL from the kernel after NL80211_CMD_RADAR_DETECT and aborts initialization sequence. I have a couple of questions regarding this issue: 1) Has anyone else noticed this too? 2) Which of these three components is wrong - regdb, cfg80211 or hostapd? -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
