Ad-hoc 网络里遇到的一个问题，有兴趣的进来一起研究。

eshao

我用两台设备使用ad-hoc对连，认证方式一个设为open,一个设置为shared,居然可以连上！！？？
无线网卡用的是ranlik,
驱动程序是：RT61_Linux_STA_Drv1.1.0.0
?
我在驱动的代码里追到下面：
?if (Reason == MLME_SUCCESS)
??????? {
??????????? // 1. joined an IBSS, we are pretty much done here
??????????? if (pAd->MlmeAux.BssType == BSS_ADHOC)
??????????? {
??????????? ??? printk("%s(%d):This a Ad-hoc net!",__FUNCTION__,__LINE__);
??????????????? LinkUp(pAd, BSS_ADHOC);
??????????????? pAd->Mlme.CntlMachine.CurrState = CNTL_IDLE;
??????????????? DBGPRINT(RT_DEBUG_TRACE, "CNTL - join the IBSS = %02x:%02x:%02x:%02x:%02x:%02x ...",
??? ??? ??? ??? ??? pAd-&gtortCfg.Bssid[0],pAd-&gtortCfg.Bssid[1],pAd-&gtortCfg.Bssid[2],
??? ??? ??? ??? ??? pAd-&gtortCfg.Bssid[3],pAd-&gtortCfg.Bssid[4],pAd-&gtortCfg.Bssid[5]);
??????????? }
??????????? // 2. joined a new INFRA network, start from authentication
??????????? else
??????????? {
??? ??? ??? ??? // either Ndis802_11AuthModeShared or Ndis802_11AuthModeAutoSwitch, try shared key first
??????????????? if ((pAd-&gtortCfg.AuthMode == Ndis802_11AuthModeShared) ||
??? ??? ??? ??? ??? (pAd-&gtortCfg.AuthMode == Ndis802_11AuthModeAutoSwitch))
??????????????? {
??????????????????? AuthParmFill(pAd, &AuthReq, pAd->MlmeAux.Bssid, Ndis802_11AuthModeShared);
??????????????? }
??????????????? else
??????????????? {
??????????????????? AuthParmFill(pAd, &AuthReq, pAd->MlmeAux.Bssid, Ndis802_11AuthModeOpen);
??????????????? }
???????????
??????????????? MlmeEnqueue(pAd, AUTH_STATE_MACHINE, MT2_MLME_AUTH_REQ,
??????????????????????????? sizeof(MLME_AUTH_REQ_STRUCT), &AuthReq);

??????????????? pAd->Mlme.CntlMachine.CurrState = CNTL_WAIT_AUTH;
??????????? }
??????? }
??????? else
??????? {
??????????? // 3. failed, try next BSS
??????????? pAd->MlmeAux.BssIdx++;
??????????? IterateOnBssTab(pAd);
??????? }?

发现，在ad-hoc 模式下，根本没有进行认证。
不知道是作者疏忽，还是协议就这么规定的？？？？？
请高手指点，
看上去，不像疏忽，但我又没有找到相关资料说ad-hoc不需要认证.........?
