Bug 336082 – sys-apps/baselayout-1.12.13 doesn't start wpa_supplicant

• Product: Gentoo Linux

When I run /etc/init.d/net.wlan0 start I get the following output:

 * ERROR:  net.wlan0 failed to start

dhcpcd is timing out because the script doesn't start wpa_supplicant. I checked whether there is a wpa_supplicant process while dhcpcd was running (via ps aux | grep wpa_supplicant and via wpa_cli status).

When I run wpa_supplicant manually my iface connects to my access point as it should. After this running dhcpcd wlan0 gets a lease and my iface wlan0 is successfully connected. What's going on? 

Reproducible: Always

Steps to Reproduce:
1. Run /etc/init.d/net.wlan0
2. dhcpcd is timing out
3.

Actual Results:  
wpa_supplicant is not started by /etc/init.d/net.wlan0

Expected Results:  
wpa_supplicant should be started by /etc/init.d/net.wlan0 so dhcpcd can fetch an IP address

[Comment 1 Matthias Herrmann 2010-09-05 12:55:13 UTC]

/etc/conf.d/net:

modules=( "ifconfig" "dhcpcd" )
modules_wlan0=("wpa_supplicant")

wpa_supplicant_wlan0="-Dwext"
config_eth0=("172.22.5.100/16")
routes_eth0=( "default via 172.22.0.1" )
dns_servers_eth0="172.22.0.1 194.25.2.129 194.25.2.130 194.25.2.131 94.25.2.132 194.25.2.133 194.25.2.134"
config_wlan0=("dhcp")
fallback_wlan0=("dhcp")

/etc/wpa_supplicant/wpa_supplicant.conf is not needed here because when I ran it manually it successfully connects to AP..

When you need more information please ask. Thx in advance

[Comment 2 Róbert Čerňanský 2010-09-09 13:28:57 UTC]

Exactly same behaviour here.  Workaround: baselayout's wpa_supplicant module needs CONFIG_WIRELESS_EXT_SYSFS kernel option to be turned on otherwise function wpa_supplicant_exists() does no pass and wpa_supplicant is not started.

As wpa_supplicant itself works fine even without mentioned kernel option it should be fixed (or at least documented).

[Comment 3 Dirk-Lüder Kreie 2010-09-30 12:50:51 UTC]

/lib/rcscripts/net/wpa_supplicant.sh should check for phy80211 instead of, or in addition to, wiphy
(line 50)

[Comment 4 Dirk-Lüder Kreie 2010-09-30 13:09:21 UTC]

Apparently this will not be fixed in baselayout:
See bug #307191

If you want wireless to work while your kernel recompiles with the DEPRECATED option CONFIG_WIRELESS_EXT_SYSFS, just patch /lib/rcscripts/net/wpa_supplicant.sh line 50 to say:
[[ -L /sys/class/net/$1/phy80211 || -d /sys/class/net/$1/wireless ]]

(phy80211 instead of wiphy)

[Comment 5 Jeremy Murphy 2011-02-20 00:42:00 UTC]

Matthias, could you please test the solutions suggested in comments #2-4 and if they work, close this bug as a duplicate of #307191.  Thanks.

[Comment 6 Richard Gration 2011-03-07 22:15:21 UTC]

I can confirm that the fix detailed in #4 works.

[Comment 7 SpanKY 2011-09-15 04:43:33 UTC]

openrc is stable now
