key_store:Using euid instead of uid when upgrade wifi blobs
The update transaction goes wrong in "KeyStoreService::upgradeKeyBlob"
function, which try to delete corresponds key blob use "KeyStore.del"
and the target key blob "filename" is generated by uid = "AID_KEYSTORE
1017" which belongs to "android.security.keystore" binder service. '
However, the target key blob is actually owned by uid = "AID_WIFI 1010".
So, we CAN NOT upgrade the wifi password definitely,and connection fail
(could not find that key blob file, because it is not EXIST).
