Two interfaces after installing + tainting kernel #138

Closed Asaf-E closed 3 months ago

Asaf-E commented 4 months ago

Hi,

After installing the driver I have two interfaces: nmcli dev wlan0 wifi disconnected -- p2p-dev-wlan0 wifi-p2p disconnected --

iw dev phy#0 Interface wlan0 ifindex 5 wdev 0x1 addr 08:be:ac:3b:eb:eb type managed txpower -100.00 dBm

Is there a method to disable the second interface from the device parameters?

Additionaly, I have the error: dmesg | grep 8821au [ 9.428902] 8821au: loading out-of-tree module taints kernel. [ 9.428974] 8821au: module verification failed: signature and/or required key missing - tainting kernel [ 11.439217] usbcore: registered new interface driver rtl8821au

I don't have "secure boot", yet this still shows, I checked and the module is signed: modinfo 8821au | grep '^sig' sig_id: PKCS#7 signer: javelin Secure Boot Module Signature key sig_key: 1C:79:D5:54:B7:92:66:ED:DA:97:6E:7D:42:77:B2:CF:18:08:18:FF sig_hashalgo: sha512 signature: 34:B0:A5:8E:A7:59:EE:71:BE:2A:98:8D:6D:1A:72:5E:DD:27:17:2F:

I'm using the kernel: uname -r 6.5.0-35-generic

I used the automatic installation.

I have been able to connect to wifi using the wlan0 interface, but I'm worried about these issues effect.

this is the dkms: dkms status r8168/8.049.02, 5.19.0-46-generic, x86_64: installed r8168/8.049.02, 6.5.0-35-generic, x86_64: installed rtl8821au/5.12.5.2, 6.5.0-35-generic, x86_64: installed

Thanks for moving.

I can't do anything about this. This is the Linux kernel maintainers telling you to stop using Realtek out-of-kernel drivers because they are not standards compliant. The driver I asked you to test is standards compliant and will be going into the kernel.

iw dev phy#0 Interface wlan0 ifindex 5 wdev 0x1 addr 08:be:ac:3b:eb:eb type managed txpower -100.00 dBm

I only see one interface.

What hardware are you using? Is this a RasPi or what?

Don't worry. There is nothing we can do as long as you are on this driver. If it works, it works.

Do you have the links to the new standards compliant driver that I posted?

I'm using a MiniPC X100-N3350

I haven't yet installed the mac80211 driver

MiniPC X100-N3350

Cool. Been thinking about getting a MiniPC myself. So this is a x86_64 based system.

Helping someone when you are not there can be a challenge but I do the best that I can.

It sounds to me like this driver is working. If and when you get ready to try the new driver, let me know.
