wpa_supplicant fails to survive connection lost

[Stefan Hellermann <stefan@the2masters.de>]

Hi Roy,

I noticed a misbehavior when loosing a wpa connection. dhcpcd is killed (okay) and then wpa_supplicant is killed, too, by /lib/rc/net/wpa_supplicant.sh.

/etc/wpa_supplicant/wpa_cli.sh is called when loosing the connection, it executes /etc/init.d/net.wlan0 stop with IN_BACKGROUND=true and this should stop dhcpcd, but not wpa_supplicant, I think.

I attached a small patch which works for me. It's obvious not correct, now wpa_supplicant isn't stopped on normal shutdown.
But: If I loose the connection now, dhcpcd is stopped. When the connection arrives again wpa_supplicant is still running and catches it. Then dhcpcd is started again. Wonderful :)

Cheers
Stefan

After looking at the logic I have corrected the patch

Tests done:

• stopping net.wlan0 normal: dhcpcd + wpa_supplicant is stopped [OK]
• stopping net.wlan0 with IN_BACKGROUND=true: only dhcpcd is stopped [OK]
• after stopping it with IN_BACKGROUND stop it again normal: only wpa_supplicant is stopped, no error [OK]
• killall wpa_supplicant, then stop net.wlan0: only dhcpcd is stopped [OK]

But this doesn't mean the patch is correct :-)

Cheers
Stefan

I'll have to look at this when I have the time.
The issue is that if wpa_supplicant is used for auth on a wired interface controlled by netplug/ifplugd.

I've now found the time - and the fix! Sorry about the delay.
