Arch Linux

Description:
My netcfg profile is a wired ethernet, static configuration with 802.11x authentication (it is listed in the end of this bugreport). It was working with netcfg 2.5.x for a long time - now after upgrading to netcfg 2.6.6 yesterday I cannot connect anymore:

# NETCFG_DEBUG=1 netcfg eduroam
DEBUG: Loading profile eduroam
DEBUG: Configuring interface eth0
:: eduroam up [BUSY]
DEBUG: status reported to profile_up as:
DEBUG: Loading profile eduroam
DEBUG: Configuring interface eth0
DEBUG: ethernet_iproute_up ifup
DEBUG: ethernet_iproute_up start_wpa eth0 /etc/wpa_supplicant.conf.eduroam wired
DEBUG: wpa_cli -p -i eth0 status

...
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

> WPA Authentication/Association Failed
DEBUG: profile_up connect failed

It seems that the argument for `wpa_cli -p` is missing. I looked into the /usr/lib/network/8021x and confirmed this. There are invocations `wpa_cli -p $WPA_CTRL_PATH ...` but the WPA_CTRL_PATH variable is not set anywhere and the documentation does not say that it should be done by the user: http://projects.archlinux.org/netcfg.git/tree/docs/netcfg-profiles.txt

However, the WPA_CTRL_PATH is being set inside /usr/lib/network/connections/wireless or /usr/lib/network/connections/wireless-dbus:

WPA_CTRL_PATH=/run/wpa_supplicant

So I guess it is just some random omission in the 80211x file.

Next thing, I did these:
- set WPA_CTRL_PATH=/run/wpa_supplicant
- netcfg still failed with "No such file or directory"
- strace showed that the file being searched for is /run/wpa_supplicant/eth0, so I added it (an empty file)
- then I got this error: "Failed to connect to wpa_supplicant - wpa_ctrl_open: Connection refused"


Additional information:
- my netcfg profile:

CONNECTION='ethernet'
INTERFACE='eth0'
IP='static'
ADDR='x.x.x.x'
GATEWAY='y.y.y.y'
DNS=('127.0.0.1')
AUTH8021X='yes'
WPA_CONF='/etc/wpa_supplicant.conf.eduroam'

- netcg 2.5.5 works without any problems, netcfg 2.6.6 fails to connect
- I use this profile and this network at my work, where I am from Monday to Wednesday. I will be happy to provide some more information and maybe test some improvements/patches, but of course it is limited to these three days a week.
