Hi everyone,
I'm porting wifi driver (Ralink chip) on Android 2.0.1 board.
first of all I made some modifies

(1) modify build/target/board/generic/BoardConfig.mk

add HAVE_CUSTOM_WIFI_DRIVER_2 := true

(2) Android using wpa_supplicant to management wifi. Make sure
external/wpa_supplicant/.config is looking like this

# CONFIG_NO_WPA=y

CONFIG_OS=unix

CONFIG_IEEE8021X_EAPOL=y

CONFIG_EAP_MD5=y

CONFIG_EAP_MSCHAPV2=y

CONFIG_EAP_TLS=y

CONFIG_EAP_PEAP=y

CONFIG_EAP_TTLS=y

CONFIG_EAP_GTC=y

CONFIG_EAP_OTP=y

CONFIG_EAP_SIM=y

CONFIG_EAP_AKA=y

CONFIG_EAP_PSK=y

CONFIG_EAP_SAKE=y

CONFIG_EAP_GPSK=y

CONFIG_EAP_PAX=y

CONFIG_EAP_LEAP=y

# CONFIG_EAP_FAST=y

CONFIG_PKCS12=y

# CONFIG_PCSC=y

CONFIG_SMARTCARD=y

CONFIG_WIRELESS_EXTENSION=y

CONFIG_CTRL_IFACE=y

# CONFIG_DRIVER_HOSTAP=y

# CONFIG_DRIVER_HERMES=y

# CONFIG_DRIVER_MADWIFI=y

# CONFIG_DRIVER_ATMEL=y

CONFIG_DRIVER_WEXT=y

# CONFIG_DRIVER_NDISWRAPPER=y

# CONFIG_DRIVER_BROADCOM=y

# CONFIG_DRIVER_IPW=y

# CONFIG_DRIVER_BSD=y

# CONFIG_DRIVER_NDIS=y

# CONFIG_DRIVER_TEST=y

# CONFIG_DRIVER_CUSTOM=y

# CONFIG_DEBUG_FILE=y

# CONFIG_INTERNAL_LIBTOMMATH=y

(3) Enable wpa_supplicant compile option, modify external/
wpa_supplicant/Android.mk

(3.1)

LOCAL_PATH := $(call my-dir)

WPA_BUILD_SUPPLICANT := true

ifneq ($(TARGET_SIMULATOR),true)

ifneq ($(BOARD_WPA_SUPPLICANT_DRIVER),)

WPA_BUILD_SUPPLICANT := true

CONFIG_DRIVER_$(BOARD_WPA_SUPPLICANT_DRIVER) = y

endif

(3.2) remove mark symbol, and look like this

########################

local_target_dir := $(TARGET_OUT)/etc/wifi

include $(CLEAR_VARS)

LOCAL_MODULE := wpa_supplicant.conf

LOCAL_MODULE_TAGS := user

LOCAL_MODULE_CLASS := ETC

LOCAL_MODULE_PATH := $(local_target_dir)

LOCAL_SRC_FILES := $(LOCAL_MODULE)

include $(BUILD_PREBUILT)

########################

(4) Modify wpa_supplicant setting file, and out/target/product/
generic/system/etc/wifi/ will be created after #make in step (3) out/
target/product/generic/system/etc/wifi/wpa_supplicant.conf

(4.1)

# The value can be set to, e.g., udp (ctrl_interface=udp)

# For Windows Named Pipe: This value can be used to set the security
descriptor

# for controlling access to the control interface. Security descriptor
can be

# set using Security Descriptor String Format (see http://msdn.microsoft.com/

# library/default.asp?url=/library/en-us/secauthz/security/

# security_descriptor_string_format.asp). The descriptor string needs
to be

# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set
an empty

# DACL (which will reject all connections). See README-Windows.txt for
more

# information about SDDL string format.

#ctrl_interface=wlan0

ctrl_interface=DIR=/data/system/wpa_supplicant/ GROUP=system

(4.2) setting default AccessPoint value:

# Only WPA-PSK is used. Any valid cipher combination is accepted.

network={

ssid="example" // AP name

proto=WPA //encypted method

key_mgmt=WPA-PSK //using psk

pairwise=CCMP TKIP

group=CCMP TKIP WEP104 WEP40

psk=06b4be19da289f475aa46a33cb793029d4ab3db7a23ee92382eb0106c72ac7bb

priority=2

}

(5) Add directory which is needed when enable wifi under linux,

System/core/rootdir/init.rc

# give system access to wpa_supplicant.conf for backup and restore

mkdir /data/misc/wifi 0770 wifi wifi

chmod 0770 /data/misc/wifi

chmod 0660 /data/misc/wifi/wpa_supplicant.conf

mkdir /data/misc/wifi/sockets 0770 wifi wifi

mkdir /data/misc/android 0770 wifi wifi

mkdir /data/system/wpa_supplicant 0770 wifi wifi

mkdir /data/misc/dhcp 0770 dhcp dhcp

chown dhcp dhcp /data/misc/dhcp

chmod 0555 /system/bin/busybox

(6) Modify HAL code, hardware/libhardware_legacy/wifi/wifi.c

Re-define the include path

#ifndef WIFI_DRIVER_MODULE_PATH

//#define WIFI_DRIVER_MODULE_PATH "/system/lib/modules/wlan.ko"

#define WIFI_DRIVER_MODULE_PATH "/lib/modules/rt3070sta.ko"

#endif

#ifndef WIFI_DRIVER_MODULE_NAME

//#define WIFI_DRIVER_MODULE_NAME "wlan"

#define WIFI_DRIVER_MODULE_NAME "ra0"

#endif

#ifndef WIFI_DRIVER_MODULE_ARG

#define WIFI_DRIVER_MODULE_ARG ""

#endif

#ifndef WIFI_FIRMWARE_LOADER

#define WIFI_FIRMWARE_LOADER ""

#endif

#define WIFI_TEST_INTERFACE "sta"

(7) Make and place driver relative file after boot.
place rt3070sta.ko at /lib/modules/
place RT2870STA.dat at /etc/Wireless/RT2870STA/ (it is driver
needed)
place libiw.so.29 at /lib (it is driver needed)

(8) select "Settings" -> "Wireless&networks" -> "Wi-Fi" in Android
I found the wifi module has been inserted. and I got the logcat.
====================
D/SettingsWifiEnabler( 1153): Received wifi state changed from
Disabled to Enabling
rtusb init --->
ra0 (usb): not using net_device_ops yet
usbcore: registered new interface driver rt2870

====================

but soon it fail and throws the log
====================
init: no such service 'wpa_supplicant'
====================

Does anyone have any suggestion or ideal????

- are u sure wpa_supplicant binary is placed in /system/bin of android filesystem?
- make sure you have wpa_supplicant launch script in init.rc (like below)

service wpa_supplicant /system/bin/wpa_supplicant \
-Dwext -ieth0 -c/data/misc/wifi/wpa_supplicant.conf
disabled

or manually start in shell
start wpa_supplicant..

Did you check your system/bin to see if wpa_supplicant was present?

Here is what's in my BoardConfig.mk in order to build wpa supplicant.

# Wifi related defines
BOARD_WPA_SUPPLICANT_DRIVER := WEXT
BOARD_WPA_SUPPLICANT_PRIVATE_LIB :=

I found that it may kernel config relative.
I open CONFIG_PACKET option in kernel.
it seems wpa_supplicant start running.
but now I have another problem.
message with **** **** is dumped by adding debug message code.

In your wpa_supplicant.conf, change your GROUP=system to GROUP=wifi.
If you create /data/system/wpa_supplicant using 0777 wifi wifi, your
group needs to be wifi so the correct permissions can be used. I had
this issue before until I changed the group, then it was able to make
the interface.

I found the problem is that the directory /data/system/wpa_supplicant
is not creat after bootup
and I change to use Group system in create all relative directories.
&
out/target/product/generic/system/etc/wifi/wpa_supplicant.conf
still with ctrl_interface=DIR=/data/system/wpa_supplicant/
GROUP=system

then there is the new log

And I also checked the wpa_supplicant source code.

aren't these problems similar to,
http://osdir.com/ml/android-porting/2009-02/msg00139.html
?

modifications are required in init.rc and .conf file - If I remember correctly (does seem a long time ago ...).

Hi, savoy
I did in wpa_supplicant.conf and init.rc
here goes my wpa_supplicant.conf & init.rc

== external/wpa_supplicant/wpa_supplicant.conf ==
# global configuration (shared by all network blocks)
#
# Parameters for the control interface. If this is specified,
wpa_supplicant
# will open a control interface that is available for external
programs to
# manage wpa_supplicant. The meaning of this string depends on which
control
# interface mechanism is used. For all cases, the existance of this
parameter
# in configuration is used to determine whether the control interface
is
# enabled.
#
# For UNIX domain sockets (default on Linux and BSD): This is a
directory that
# will be created for UNIX domain sockets for listening to requests
from
# external programs (CLI/GUI, etc.) for status information and
configuration.
# The socket file will be named based on the interface name, so
multiple
# wpa_supplicant processes can be run at the same time if more than
one
# interface is used.
# /var/run/wpa_supplicant is the recommended directory for sockets and
by
# default, wpa_cli will use it when trying to connect with
wpa_supplicant.
#
# Access control for the control interface can be configured by
setting the
# directory to allow only members of a group to use sockets. This way,
it is
# possible to run wpa_supplicant as root (since it needs to change
network
# configuration and open raw sockets) and still allow GUI/CLI
components to be
# run as non-root users. However, since the control interface can be
used to
# change the network configuration, this access needs to be protected
in many
# cases. By default, wpa_supplicant is configured to use gid 0 (root).
If you
# want to allow non-root users to use the control interface, add a new
group
# and change this value to match with that group. Add users that
should have
# control interface access to this group. If this variable is
commented out or
# not included in the configuration file, group will not be changed
from the
# value it got by default when the directory or socket was created.
#
# When configuring both the directory and group, use following format:
# DIR=/var/run/wpa_supplicant GROUP=wheel
# DIR=/var/run/wpa_supplicant GROUP=0
# (group can be either group name or gid)
#
# For UDP connections (default on Windows): The value will be ignored.
This
# variable is just used to select that the control interface is to be
created.

# The value can be set to, e.g., udp (ctrl_interface=udp)
#
# For Windows Named Pipe: This value can be used to set the security
descriptor
# for controlling access to the control interface. Security descriptor
can be

# set using Security Descriptor String Format (see http://msdn.microsoft.com/

# library/default.asp?url=/library/en-us/secauthz/security/
# security_descriptor_string_format.asp). The descriptor string needs
to be
# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set
an empty
# DACL (which will reject all connections). See README-Windows.txt for
more
# information about SDDL string format.
#
#ctrl_interface=wlan0
ctrl_interface=DIR=/data/system/wpa_supplicant/ GROUP=system

== system/core/rootdir/init.rc ==

# give system access to wpa_supplicant.conf for backup and restore

mkdir /data/misc/wifi 0770 system system
mkdir /data/misc/wifi/sockets 0770 system system
mkdir /data/system 0775 system system
mkdir /data/system/wpa_supplicant 0770 system system

mkdir /data/misc/dhcp 0770 dhcp dhcp
chown dhcp dhcp /data/misc/dhcp
chmod 0555 /system/bin/busybox

and after booting up, I checked the directory, /data/system/
wpa_supplicant & /data/misc/wifi/sockets both exist
but it still can't connect. just don't know why???

I am not sure it's gonna help - but when I faced this kind of problem.
I stopped trying it from GUI.

I made sure - my supplicant ran from console (as root), I tried connecting with a wpa_cli and did all the steps in wifi.c manually (inserting modules/fw_download or whatever is specific to chip)

Only then issues with UI become easier to crack.
(sorry for the suggestion being more philosophical than technical).

I think stop trying it from GUI maybe a good idea.
and I figure out why fail. because I pass ctrl_path /data/system/
wpa_supplicant/ra0 to wpa_ctrl_open
but I didn't creat "ra0" this directory under /data/system/
wpa_supplicant
after I creat directory ra0, log has changed.

E/Wap_Supplicant( 963): wpa_ctrl_open (3)ctrl_path=/data/system/
wpa_supplicant/ra0
E/Wap_Supplicant( 963): wpa_ctrl_open (5)dest.sun_path=/data/system/

there are one thing strange.
I think code flow in wpa_ctrl_open() ( wpa_ctrl.c ).
it should go into #ifdef ANDROID, but not outside.

I found that it will check the first char in ctrl_path, it can't be
"/".
or it will go outside. unfortunately, I just gave the path "/"data/
system/

#ifdef ANDROID
chmod(ctrl->local.sun_path, S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP);
chown(ctrl->local.sun_path, AID_SYSTEM, AID_WIFI);
/*
* If the ctrl_path isn't an absolute pathname, assume that
* it's the name of a socket in the Android reserved namespace.
* Otherwise, it's a normal UNIX domain socket appearing in the
* filesystem.
*/

LOGE("wpa_ctrl_open (3)ctrl_path=%s ",ctrl_path);

if (connect(ctrl->s, (struct sockaddr *) &ctrl->dest,
sizeof(ctrl->dest)) < 0) {

close(ctrl->s);
unlink(ctrl->local.sun_path);
os_free(ctrl);

LOGE("wpa_ctrl_open (5)");
return NULL;
}

return ctrl;
