无线配置struct cfg80211_ops调用问题

haotianmai

小弟近日在调试wifi"身份认证出现问题"的BUG时，经过定位发现是static struct cfg80211_ops rtw_cfg80211_ops的成员函数add_key没有调用。但我搜索整个linux kernel3.0的代码都没找到。

想请高手指点下add_key到底是哪调用的。这个问题已搞了3天了，小弟不甚感激。

    你没有给出代码，与具体的情况描述，这个没有人能帮你。

//变量定义在\linux3.0\drivers\net\wireless\rtl8188eu\os_dep\linux\ioctl_cfg80211.c
static struct cfg80211_ops rtw_cfg80211_ops = {
        .change_virtual_intf = cfg80211_rtw_change_iface,
        .add_key = cfg80211_rtw_add_key,
        .get_key = cfg80211_rtw_get_key,
        .del_key = cfg80211_rtw_del_key,
        .set_default_key = cfg80211_rtw_set_default_key,
        .get_station = cfg80211_rtw_get_station,
        .scan = cfg80211_rtw_scan,
        .set_wiphy_params = cfg80211_rtw_set_wiphy_params,
        .connect = cfg80211_rtw_connect,
        .disconnect = cfg80211_rtw_disconnect,
        .join_ibss = cfg80211_rtw_join_ibss,
        .leave_ibss = cfg80211_rtw_leave_ibss,
        .set_tx_power = cfg80211_rtw_set_txpower,
        .get_tx_power = cfg80211_rtw_get_txpower,
        .set_power_mgmt = cfg80211_rtw_set_power_mgmt,
        .set_pmksa = cfg80211_rtw_set_pmksa,
        .del_pmksa = cfg80211_rtw_del_pmksa,
        .flush_pmksa = cfg80211_rtw_flush_pmksa,
             .......
}

问题描述如下：
机顶盒(系统android 4.0)反复进行待机唤醒操作，会出现wifi显示断开，进入我的-设置页面无线连接提示“身份验证出现问题”
此时将wifi关闭，再重新开启。则连接成功。出现概率:4/20。

    其它我不知道。最大的可能，与你在SUSPEND之后，没有调用正确的初始化相关，但这个正确的初始化，要APPLICATION，与KERNEL配合的，现在我不能确定，是你哪一层没有正确初始化。你第一步检查，KERNEL 在SUSPEN RESUME的操作与INIT DEINIT是不是相似，如果这个相似，再检查APPLICATION是否也是正确的操作了。感觉最大的可能还在APPLICATION这一层。因为这个认证的KEY，是APPLICATION进行设置的。

haotianmai

小弟非常感谢指导。

我这里没有application层代码，只能检查kernel那一步了。

haotianmai

囧 刚发现我这里也有android自带的apps源代码， 也包括wifi的设置应用程序
