wpa_supplicant not working - Buster (Kernel memory exposure)

Postby stealthtech » 2019-08-13 20:30

I assume this is not a driver issue, I can run the following command, which I assume uses the wireless device, to get a list of access points.
In addition to that the GUI NetworkManager shows the list of networks as well.
Once I try to connect wireless crashes and I can not longer see a list or do anything with wireless until I restart services.
One more thing, this was working in Stretch
Code: Select all
sudo iw wlan0 scan

I'm getting this error when I run wpa_supplicant.
I started with the GUI NetworkManager and was having the issue.
After that I started to use terminal to troubleshoot and was getting the same issue as if I tried to configure and connect with NetworkManager.

usercopy: Kernel memory exposure attempt detected from SLUB object 'dma-kmalloc-4096' (offset 144, size 121)!

I have a Broadcom Limited BCM4306 rev 03
Code: Select all
sudo lspci | grep BCM

For troubleshooting I run the following

Code: Select all
sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf

Successfully initialized wpa_supplicant

Yes, I'm assuming the drivers are working otherwise I would not get a list of available networks.
Wireless crashes at the time of connecting to a network.

Re: wpa_supplicant not working - Buster (Kernel memory expos

One test I did not do was a test without WPA to see if the issue is truely with wpa_supplicant by way of not using it. The last comment got me thinking, just because I can list the networks does that mean I'm using all of the features of the network driver. I was also thinking that wpa_supplicant works for others who might not have the same network driver. To that end I had to eliminate WPA2 from the equation and if it works without it then more than likely the issue is with wpa_supplicant. Well as it turns out it does no work without WPA2. Which now I'm thinking it might be an issue with something other than wpa_supplicant.

This also begs the questions, am I the only one using a bcm43xx, which I don't think so. Which then raises the question, what is so different with my setup that with Stretch it works and with a clean install of Buster it does not. If it works with other why not mine.

I setup a guest network on my router without WPA2, I set it up as an open network.

Re: wpa_supplicant not working - Buster (Kernel memory expos

Postby stealthtech » 2019-08-14 20:07

After further testing I come to the conclusion that the issue is not with wpa_supplicat nor is the issue with dhclient. The issue has something to do with what those two services use that causes the problem, either with the driver itself or something all together differently.

Knowing I was able to connect without WPA there was still an issue with dhclient. So I eliminated that from the equation.

This is not a desirable solution
1. Open Network
2. Static IP Address

Because I was able to get things to work for an open network using a static IP address, I thought I could use a static IP Address with a WPA but that did not work. I think wpa_supplicant crashes even before doing anything with assigning an IP Address by using DHCP or static IP Address.
