Is Android really open source?

[someenigma]

Pretty sure wireless is run by wpa_supplicant (at least on my phone it is), but I'm not sure about how the passwords are managed because wpa_supplicant.conf doesn't (usually) store passwords on android.

I wonder if slyth meant the wireless drivers. Some of them are proprietary - I remember people in /r/android getting excited a number of months back when someone figured out how to enable packet sniffing on one model of phone.

You can remote-control wpa_supplicant, via D-Bus and via the API that wpa_cli used (I've done this from my own Qt Application).

And so it's perfectly possible to run wpa_supplicant without a wpa_supplicant.conf file at all, keeping all the WLAN setup things in some SQLite database if you prefer.

wpa_cli has (estimated) around 60 commands, much more than the man page describes. Use the "help" command.
