Is there a bug in those checks? > You know I'm a newbie at this networking... I obviously had no idea about WLAN_CIPHER_SUITE_AES_CMAC until you mentioned it. I just looked at the other implementations of del_key() etc and they checked it. Monkey see, monkey do. My concern when I wrote this patch was places like __cfg80211_clear_ibss() which just do: for (i = 0; i < 6; i++) rdev->ops->del_key(wdev->wiphy, dev, i, false, NULL); That's what triggers the Smatch warning as well. But as I said, I'm quite a newbie at this code. regards, dan carpenter -- 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
