[Virtual-pkg-base-maintainers] Bug#867364: base: wlan configuration error crashes entire driver

[Markus]

Package: base
Severity: normal

Dear Maintainer,


I was configuring automatic wlan connectivity for my RasPi with PIXEL (Debian based).
I manipulated the wpa_supplicant file in /etc/wpa_supplicant directory just to
change connection priorities and made a spelling error. I Forgot closing
bracket "}" for one of the connections (the first one). When I rebooted the 
device, I found out that I had no wlan connectivity. Not only were the 
preset connections obviously missing, since the wpa_supplicant file was
effectively corrupted, but the whole wifi driver seemed to have crashed and
I could not connect to or even see any networks nearby. In fact the device
(RasPi 3 that has an inbuild wifi module) seemed to have no wifi device.

This was completely fixed by addign the missing bracket.

I thought to report this as it seems to me at least that in this kind of a 
situation the wifi driver should be able to recover from corrupted configuration 
file and possibly give a prompt that it indeed is corrupted, and
continue as is with default settings.
