netd crash 当Wifi和3G进行切换的时候，netd crash,概率 10%，出现这样问题关键是怎么定位问题？solution一般比较简单。

从backtrace上看netd crash在#00 pc00005cc0 /system/bin/netd点上，找到想对应的netd（请注意，这个netd不是system/bin/netd，这个文件不包含debug信息，而应该是system/symbol下面的netd，可能各个platform不太一样）利用gdb进行解析，
输入 b * 0x00005cc0
也可以通过arm-eabi-objdump -D -S netd把汇编传出来，确认一下问题。
找到BandwidthController.cpp中的675行
这是函数intBandwidthController::setInterfaceQuota(const char *iface, int64_t maxBytes) 中的it->ifaceName==ifaceName
ifaceName是传进来的一个参数，我们确认是正确的，在这个也没有被修改,而quotaIface是一个全局变量，这才是我们要怀疑的真正的点，同时在多线程中可能被修改。这里实际上有到了多线程保护的问题。接下来是问题的确认，netd模块模块处理的一些命令都是从NetDemondControl传下来的，基于这一点，我们可以在这个模块中加入test commnd然后在BandwidthController进行处理这样就可以缩小问题的范围。
//this test function.
int BandwidthController::BandwidthControllerTest()
{
ALOGV("func=%s,quotaAddr=0x%p", __func__,"aIfaces);
if(quotaIfaces.size()<=0)
{
ALOGV("func=%s,size=%d", __func__,NULL);
}else
{
ALOGV("func=%s,size=%d", __func__,quotaIfaces.size());
}
return 0;
}
最后发现是在函数中
int SoftapController::startDriver(char *iface) {
int ret;
ALOGE("%s\n",__func__);
if (mSock < 0) {
ALOGE("Softap driver start - failed to open socket");
return -1;
}
if (!iface || (iface[0] == '\0')) {
ALOGD("Softap driver start - wrong interface");
iface = mIface;
}
*mBuf = 0;
ret = setCommand(iface, "START");
if (ret < 0) {
ALOGE("Softap driver start: %d", ret);
return ret;
}
#ifdef ATH_STA_AP_CONCURRENT
if(isConcurrentMode()) {
char cmd[32]="p2p_group_remove p2p0";
char buf[32];
unsigned int len ;
ret = connect2Supplicant(ATH_P2P_IFACE);
if (ret < 0) {
ALOGE("Softap connect to p2p failed: %d", ret);
return ret;
}
#if 1
memset(buf,0,32);
len = sizeof(buf);
ret = sendSupplicantCommand(ATH_P2P_IFACE, cmd, buf, &len);
if (ret < 0) {
ALOGE("Softap send p2p cmd \"%s\" failed: %d",cmd, ret);
return ret;
}
closeSupplicantConnection(ATH_P2P_IFACE);
把这部分code去掉以后，问题就dispear了，到这里有可以迷茫了，这下层的东西都是common的，问题应该还是处在netd模块。但问题到底在哪里呢？SoftapController这个controller是为athros新加不是google原始。
最后发现是commandlistener.h中的头文件包含出现问题引起的，这是由于 wifi engineer在porting wifi的时候出现失误导致的问题。
//#include "SoftapController.h"
#include "SoftapControllerAtheros.h"
#endif
ifc_init();
ret = ifc_down("p2p0");
ifc_close();
if (ret < 0) {
ALOGE("Softap concurrent p2p %s down: %d", iface, ret);
return ret;
}
strncpy(nl_cmd_cfg.iface, "wlan0", 32);
if ((ret = nl80211_init(&nl_cmd_cfg))) {
ALOGE("couldn't init nl80211!: %s\n", strerror(errno));
return ret;
}
if ((ret = nl80211_sap_if_add(&nl_cmd_cfg, ATH_CONCURRENT_SAP_IFNAME))) {
ALOGE("couldn't add sap if: %s\n", strerror(errno));
nl80211_deinit(&nl_cmd_cfg);
return ret;
}
nl80211_deinit(&nl_cmd_cfg);
}
#endif
#ifdef HAVE_HOSTAPD
ifc_init();
if(isConcurrentMode())
ret = ifc_up(ATH_CONCURRENT_SAP_IFNAME);
else
ret = ifc_up(iface);
ifc_close();
#endif
usleep(AP_DRIVER_START_DELAY);
ALOGD("Softap driver start: %d", ret);
return ret;
}
