iwd needs restart after suspending

iwd needs restart after suspending

[Joachim Breitner]

Hi,

On my Lenovo Thinkpad X1 Carbon Gen 9 I observe that after suspending,
WLAN connectivity is gone, and `iwctl station list` no longer shows any
devices. They come back with `systemctl restart iwd`.

I had this before upgrading to NixOS 22.05, but then it was fixed. But
it came up when I switched the kernel from 5.15 to 5.19. This is using
iwd-1.27.

Is this a known problem? If not, any information in particular I could
provide to fix it?

Cheers,
Joachim

(NB, also tracking this at https://github.com/NixOS/nixpkgs/issues/186274)

I recorded the output of iwd -d on 5.15 and 5.19, see attachement. The
relevant bit seems to be

We should add this to our debug output, but what driver / hardware are you using?

So with 5.15, the underlying netdev is disconnected.  We get notified of that 
and start scanning.

Here, we receive what looks to be an IFDOWN event.

So the question is why is the kernel changing this behavior?  iwd is not aware 
of resume/suspend, so I'm not sure we can tell whether the ifdown event came 
from the user manually bringing down the device or due to suspend / resume.

What does rfkill look like on 5.15 & 5.19 after resume?

I could narrow it down to 5.15 vs. 5.17, if that helps. But 
linux/drivers/net/wireless/intel/iwlwifi seems to be a rather busy
directory:

On 5.19, before suspend, after suspend and after restarting iwd it is
always simply

~ $ LANG=C rfkill
ID TYPE      DEVICE                   SOFT      HARD

Hi Joachim,

>    Model: "Intel Wi-Fi 6 AX201"

Ok, we should have one of these to test on our side.  But so far I see nothing 
to indicate that this is an iwd bug.  Seems like a kernel regression?  I would 
file a bug against the kernel or check if something like this already exists. 
See bugzilla.kernel.org.

That would help, but ideally we need a bisected commit or something else 
concrete to work with.  Do you see anything suspicious in dmesg?

Yeah, but bisecting this with all the manual rebuilding, rebooting,
suspending sounds daunting…

Hmm, maybe this is suspicious?

Unfortunately, no resolution in that thread. I’ll try to follow up
there.
