Bug 163319 – net-wireless/wpa_supplicant-0.5.7 enters infinite loop

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Vladimir Pouzanov 2007-01-22 20:29:39 UTC]

I have a problem with restarting wlan interface using wpa_supplicant module. First start seems to pass ok, but as soon as I issue /etc/init.d/net.ath0 restart I can't make it work anymore.

First run:
Jan 22 22:22:53 unicorn sudo: farcaller : TTY=pts/3 ; PWD=/home/farcaller ; USER=root ; COMMAND=/etc/init.d/net.ath0 start
Jan 22 22:22:55 unicorn rc-scripts: WARNING:  net.ath0 has started but is inactive

Jan 22 22:22:57 unicorn dhcpcd[26077]: ath0: adding default route via 192.168.0.1 metric 2000

ath0 works, now restarting:

I can't stop it now using gentoo way:
$ sudo /etc/init.d/net.ath0 stop
 * ERROR:  net.ath0 is already stopping.

Reproducible: Always

Steps to Reproduce:

$ cat /etc/conf.d/wireless
modules=( "wpa_supplicant" )
wpa_supplicant_ath0="-Dmadwifi"

config_ath0=( "dhcp" )

$ cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
        ssid="test"
        psk="very big test key"
        proto=RSN
        priority=150
        key_mgmt=WPA-PSK
        pairwise=CCMP
}

[Comment 6 Roy Marples (RETIRED) 2007-01-24 12:20:29 UTC]

wpa_supplicant is doing it's job as the ath0 interface is reporting a disconnect.

[Comment 7 Vladimir Pouzanov 2007-01-24 17:45:13 UTC]

isn't that strange for PCI card to report disconnection? And there's no such problem after booting, i.e. when net.ath0 starts up for first time, only restart causes this

[Comment 8 Vladimir Pouzanov 2007-04-10 20:53:24 UTC]

Can't reproduce it anymore.
