[1.7.2.4 -> 1.7.3] WEP Connecting fails

[Cem Aydin]

After update from 1.7.2.4-10 to 1.7.3-1 on Arch Linux connecting using WEP encryption fails.

Downgrading to the previous version solves the issue.

Using wicd and wicd-gtk.

/var/log/wicd/wicd.log output when using HEX
After clicking connect in wicd-client.
(This used to work.)

It says bad_pass but I double/triple-checked it. It's the correct pass + it used to work before...

When I start the client from terminal I get:

Thanks

[Pieter Leclerc (pieterleclerc-deactivatedaccount)]

It seems to be using wlan0 and eth0 but also gets these errors:

ctrl_ifname: wlan0 error: No such file or directory
ctrl_ifname: eth0 error: No such file or directory

Can you attach the output of "ifconfig -a" and also ensure the names of the wired and wireless interfaces in your WICD settings are correct? Thanks!

[Cem Aydin (cem-aydin)]

Yes that's correct.

wlan0 and eth0 are the correct names and they are also set in wicd-client settings.

The other settings are at their defaults (Automatic etc.)

I don't know why it's giving these errors...

I'd be glad to do more testing or provide information, upon instructions.

I also tried to uninstall, remove all the config files, and reinstall, but it had no effect.
Though I'm not absolutely sure if I got all the configs... I could try that again.

Connecting to the wired network does work. Log:

[Pieter Leclerc (pieterleclerc-deactivatedaccount)]

Thanks for the help. The current primary suspect is that "2015/02/08 16:23:14 :: WPA_CLI RESULT IS None" message.

This can happen for various reasons (https://bbs.archlinux.org/viewtopic.php?id=70158 which refers to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/344022 etc...)

Anyway, you can do this manually with:

sudo wpa_cli -i wlan0 status

Which, in my case, outputs something like:

bssid=b5:76:0e:aa:99:b9
ssid=lkajzeakzje
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=CCMP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED
ip_address=192.168.20.180
address=c8:f7:33:c9:ee:c4
uuid=472c20d3-2d19-564a-807a-1b4a7b5165e9

Can you try this as well and attach the output? Also, if this works, can you make the connection fail again and attach the output of "dmesg" to see any kernel error messages and "sudo lsusb -vvv" to see the hardware you have? Thanks!

[Cem Aydin (cem-aydin)]

Ok, I get an error with this:

[Cem Aydin (cem-aydin)]

When it's because of wpa_cli, I don't understand why it works with the previous wicd version.
Additionally I don't even use wpa but wep...

But thanks anyways so far.

[Cem Aydin (cem-aydin)]

But I can understand that it might have to do with my hardware and router combination, or so... Since I think this is a common problem (the combination of different "clients" and routers etc.).

[Pieter Leclerc (pieterleclerc-deactivatedaccount)]

wpa_supplicant is used for all types of encryption, including WEP, WPA,...

In your "sudo ifconfig -a" it seemed wlan0 was up. But in the "sudo wpa_cli -i wlan0 status", it seems down. Perhaps because some time had passed, and perhaps this points to the problem...

Can you do "sudo ifconfig wlan0 up" and right after that a "sudo wpa_cli -i wlan0 status; echo $?" to be sure? Thx :-)

[Cem Aydin (cem-aydin)]

Ah, okay then.

> Can you do "sudo ifconfig wlan0 up" and right after that a "sudo wpa_cli -i wlan0 status; echo $?" to be sure? Thx :-)

Yes, of course:

I tried it with wicd service stopped and running, both times the same.
I tried what happens when the downgraded wicd is installed and when the wlan is not connected, I get the same:

~~~

However, when the wlan is connected, by clicking "Connect" in wicd-client first (which works with the downgraded version), I get:

~~~

So the error before connecting is basically the same...

[Ron Coit (ron-coit)]

I can confirm I have the same problem with 1.7.3-1 on Arch Linux, but I would like to add that I can connect to WPA/WAP2 connection without problem. It only fails on WEP connections. It seems to connect and then reports bad password and fails, but a WPA/WPA2 connection will connect everytime.

[CarloSalvatore (carlosalvatore)]

Hi, I use Gentoo and can confirm what Ron Coit says. Yet, when connecting, wicd complains of bad password if it were WPA not WEP. I have tried setting Key Index in [0,4] without success.

[Pieter Leclerc (pieterleclerc-deactivatedaccount)]

Do you feel like trying to do a "git bisect" between 1.7.2.4 and 1.7.3 to find the commit that breaks everything? It's like magic :-)
The "translation update" commits can be skipped ("git bisect skip") because I don't think they caused the regression...

[Axel Beckert (xtaran)]

Hi Tom,

I'm affected via Debian by that issue, too. You suggest to use "git bisect", but https://code.launchpad.net/~wicd-devel/wicd/experimental only seems to have a Bazaar, not a Git repo. And there's no wicd repository on https://github.com/tomvanbraeckel?tab=repositories

[Axel Beckert (xtaran)]

I think it has something to do with parsing and writing wpa_supplicant configurations.

One of my affected networks uses WEP and surely had a working configuration of type "wep-hex" before. Nevertheless the network showed up in wicd-curses as "wpa-hex" instead of "wep-hex". After fixing this via wicd-curses, I had the line "wep_key0=S_KEY" (literally, i.e. an unexpanded variable name inside the wpa_supplicant configuration file. Of course wpa_supplicant choked on it:

Successfully initialized wpa_supplicant
Line 7: Invalid WEP key 0 '$_KEY'.
Line 7: failed to parse wep_key0 '$_KEY'.
Line 11: failed to parse network block.
Failed to read or parse configuration '/var/lib/wicd/configurations/00…'.

Removing that aforementioned line (the correct key was still in line 8, also prefixed with "wep_key0="), wpa_supplicant can easily authenticate in that network again. Doesn't help for wicd as it seems to rewrite that file again before connecting and adds the" $_KEY" again.

[Axel Beckert (xtaran)]

https://bazaar.launchpad.net/~wicd-devel/wicd/experimental/revision/822 seems to be the culprit: It adds a loop over all matches and writes the line with the current match being replaced to the file. If there are two matches in the line, the line is written back twice: Once with only the first match being replaced and one line with both matches being replaced.

This didn't hurt in the initial case (https://launchpad.net/bugs/897399) where there is no syntax validation and the second line seems to simply overrule the first line. But wpa_supplicant seems to try to validate hex keys if they're really hex and that's probably the reason why only WEP cases are affected.

Should be easy to solve by moving the actual appending outside the loop. I'll try to come up with a patch.

Attached the patch as I plan to incorporate in the Debian package. See also
