wpa_supplicant icd2 plugin

[MerlijnWajer]

Seeing that we're probably going to switch to icd2 soon, we have to look at wpa_supplicant plugin.

There's this thread: http://maemo.org/community/maemo-developers/libicd-network-wpa/?org_openpsa_qbpager_net_nemein_discussion_posts_page=1

I downloaded the repo from http://web.archive.org/web/20090310161342/http://svn.javispedro.com:80/libicd-network-wpa/trunk/

Everything is there, except for gconf/network-type.xml

There are also 5 revisions missing (there is a revision 16 somewhere on archive.org, but that's also not a complete snapshot and more useless).

Does anyone else have a more recent version? Or shall we just take inspiration from this repo and start hacking a new one?

[MerlijnWajer]

Maybe the guy is still around, and we can just ask him.

[sicelo]

Yes, he is around (at least on Twitter - same username)

[MerlijnWajer]

Want to direct him to our webpage/maemo-thread and/or IRC? :)

[sicelo]

Let me see if I can :)

[MerlijnWajer]

See https://garage.maemo.org/projects/libicd-wpa/

[javispedro]

Yes, I mirrored everything to the Garage git repository.

However, take into an account I didn't have much idea how ICD worked at the time, nor there is any GUI for configuring it or anything.

[MerlijnWajer]

@javispedro I see - thanks. Do you have any interest in perhaps working on this? We have open source icd2 and also connui.

[javispedro]

Sadly no -- too busy.

[MerlijnWajer]

I will see if I can have a basic thing working on wednesday.

[MerlijnWajer]

Maybe take this https://github.com/community-ssu/libicd-network-wlan and convert it to wpa_supplicant.

[MerlijnWajer]

Very much wip, doesn't do anything yet, but compiles, when I verify it does the right things icd2-api wise, I will add in my wpa_supplicant code. https://github.com/maemo-leste/libicd-network-wpasupplicant

[MerlijnWajer]

OK, I got it to respond to scans. For my own reference, there are python dbus examples here: https://w1.fi/cgit/hostap/tree/wpa_supplicant/examples

@parazyd - could you reflect on what would be the best way to start wpasupplicant with dbus enabled? It cannot be set from config, and I currently just edited the devuan networking scripts. We need a better solution.

[MerlijnWajer]

Oh, and there is the API doc: https://w1.fi/wpa_supplicant/devel/dbus.html

[MerlijnWajer]

Made some progress by flensing libicd-network-wlan and adding basic wpa supplicant support. This is just a synthetic test:

22:48 < Wizzup> do you perhaps have a list/clue for wlancond properties
22:48 < Wizzup> or 'capabilities'
22:48 < Wizzup> the wlan plugin just has a few defines that pali added that come out of nowhere
22:49 < freemangordon> would that help https://github.com/maemo-leste/connui-wlan/blob/master/wizard/wlan.c#L20
22:49 < freemangordon> I've copied those from wlan plugin
22:51 < freemangordon> Wizzup: this https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L434 should help as well imo
22:51 < Wizzup> ok
22:51 < Wizzup> I am trying to figure out what properties I need to set (and where exactly) to have the settings wizard recognise it as EAP
22:52 < Wizzup> I think now the header that you linked me last time with the huge ascii table comes into play
22:52 < Wizzup> but maybe this is yet again different from the int values in gconf
22:52 < freemangordon> see https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L587 as well
22:52 < Wizzup> I am unhappy with keeping all this wlancond mess
22:52 < Wizzup> but I don't see a better way for now
22:52 < freemangordon> :nod:
22:53 < Wizzup> WLAN_CAP_SECURITY_WPA_EAP aha
22:53 < Wizzup> this is mentioned neither in the wlan plugin nor in icd2
22:53 < Wizzup> I suspect that this is part of higher bits of nwattrs
22:54 < Wizzup> and only the settings wizard and easy-wlan deal with it
22:54 < Wizzup> so this is part of connui header
22:55 < freemangordon> maybe we should make https://github.com/maemo-leste/connui-common/blob/master/include/iap-network.h#L13 64 bit or add
                       another var in that structure
22:55 < freemangordon> and use (if 64 bits) high 32 for whatever needed
22:56 < Wizzup> well, I am not sure if we have to
22:56 < Wizzup> I do not need more space for now
22:56 < Wizzup> so I think we can do it later
22:56 < freemangordon> ok
22:57 < freemangordon> Wizzup: in the meanwhile if you manage to find where those
                       https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L613 values come from, it would be great
22:58 < freemangordon> so we would be able to use defines instead of the values I hardcoded
22:58 < Wizzup> ok
22:59 < Juesto> a ide would be excellent to figure that out easily
23:01 < Wizzup> freemangordon: I think I know
23:01 < freemangordon> hmm?
23:01 < Wizzup> sec
23:02 < Wizzup> hm, maybe nvm
23:02 < Wizzup> I thought it was from connui/wlan-common.h with some extra shifts
23:04 < Wizzup> from here https://github.com/maemo-leste/connui-common/blob/master/include/wlan-common.h#L11
23:05 < freemangordon> could be
23:05 < freemangordon> maybe I should feed eapd in ida, it might give some clue
23:06 < Wizzup> I would not do that
23:06 < Wizzup> I got this
23:08 < Wizzup> I don't understand why they had to do all this bitshifting
23:08 < Wizzup> it's not like this is where they will really save on memory

23:14 < Wizzup> freemangordon: I think these two together are key https://github.com/maemo-leste/connui-common/blob/master/include/wlan-common.h
                https://github.com/maemo-leste/connui-common/blob/master/include/libicd-network-wlan-dev.h for
                https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L434
23:15 < Wizzup> this is confusing:
23:15 < Wizzup> return ~((unsigned int)~(iap_security << 12) >> 12);
23:17 < Wizzup> freemangordon: I think that values from https://github.com/maemo-leste/connui-wlan/blob/master/wizard/wlan.c#L20 can be placed here
                for example https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L485
23:17 < Wizzup> and here https://github.com/maemo-leste/connui-internet/blob/master/src/settings/easy-wlan.c#L515
23:17 < Wizzup> freemangordon: let's pick this up after vkbd
23:18 < Wizzup> I can let WPA_EAP rest for a bit anyway
23:18 < Wizzup> mind if I paste this in the wlan issue?
23:18 < freemangordon> no, why should I
23:19 < Wizzup> just think it's nice to ask
23:19 < Wizzup> :)
23:19 < freemangordon> :)

[MerlijnWajer]

btw, wlan-ng has working open, WEP (I think) and WPA-PSK networking with wpa_supplicant.

It doesn't work nicely with the easy-wlan wizard yet, but when configured from settings->internet connectivity, it works fine.

[MerlijnWajer]

There is now libicd-network-wpasupplicant in the repos. It's less than alpha quality, but if you know how to use it, it works stable. It's pre-alpha quality, but if you know how to use it, it works quite well. I will be working on making it stable quality - main things right now are missing eap support and the fact that you should not use the status area applet to connect to a new, unknown network. Just do it from settings->internet connectivity.

[MerlijnWajer]

There are definitely things to improve here still, but I'm going to close this ticket, since I think the state of this plugin is good enough for the alpha.

[MerlijnWajer]

Oh, and just for the record, easy-wlan (adding/connecting directly from scan results) should not also work.
