wpa_supplicant中产生__cfi_check错误crash解法

wifi的crash问题在于以下指定几个wpa会用到的so。wpa该平台是原生的，以下几个s0用原生的就行了。用mtk的hal层的s0会出错我想是因为wpa在mtk的平台不是存原生，加了很多接口以及patch，以及重载了很多原生函数，所以以下的s0能接上mtk平台的wpa。而mtk的wpa放在别的平台，因为这些patch 的修改还牵扯到framwork一些service的启动，直接cp mtk 的wpa到别的平台编译不过。如果能够把相关wpa的patch及framwork层修改移过来，编过，配下面几个s0使用我相信也是能跑起来。
