#6405 closed bug (fixed)

Unable to disable wireless interface

Reported by: pulkomandy Owned by: axeld
Priority: normal Milestone: R1
Component: Network & Internet/Stack Version: R1/alpha2
Keywords: Cc:
Blocked By: Blocking:
Platform: All


I use wired network on my laptop and usually disable the wireless card to not be annoyed with connections to random access points floating around.

However, something in the last two days completely broken disabling an interface. I tried both the network preferences panel and the ifconfig command line. Both gave me a kernel panic in the same place. It seems 100% reproductible.

The panic is triggered in headers/private/kernel/util/DoublyLinkedList.h:512 , called from ethernet_down.

I wasn't sure what to do from there, so please tell me if I can help debugging it in any way. I didn't try doing the same on another network interface.

How exactly did you disable the interface per ifconfig? I could imagine that the UI change might work after a reboot, though.

Apart from that, removing interfaces is currently not implemented since I reworked the stack internals. I'll fix that later.

I simply did ifconfig /dev/net/atheroswifi/0 down , and it crashed the same way as in the GUI. Currently I work around this by setting it to a dummy static IP, so that it just can't work.

Resolution: fixed

Works fine again as of hrev37894.

That's not entirely satisfying, as I couldn't reproduce that bug. Maybe hrev37872 or hrev37884 made a difference, though.
