Hi,
We noticed the following segfault in iwd 1.28:
... iwd is handling a SIGTERM ...
Jul 14 18:14:39 localhost iwd[2867]: ../iwd-1.28/src/device.c:device_free()
Jul 14 18:14:39 localhost iwd[2867]: ../iwd-1.28/src/wiphy.c:wiphy_free() Freeing wiphy phy0[0]
Jul 14 18:14:39 localhost iwd[2867]: ../iwd-1.28/src/netdev.c:netdev_free() Freeing netdev wlan0[45]
Jul 14 18:14:39 localhost systemd[1]: iwd.service: Main process exited, code=dumped, status=11/SEGV
Jul 14 18:14:39 localhost systemd[1]: iwd.service: Failed with result 'core-dump'.
Here is the backtrace from the core dump I got:
(gdb) bt

#8 0x0000aaaab751e9bc in main (argc=<optimized out>, argv=<optimized out>)
at ../iwd-1.28/src/main.c:602
I've attached logs as well. It looks like a use after free by netdev:
static void netdev_connect_free(struct netdev *netdev)
{
if (netdev->work.id)
wiphy_radio_work_done(netdev->wiphy, netdev->work.id);
where netdev->wiphy has already been freed.
I have been reproducing this on our brcmfmac-based platform by adding
the following to the .service file:
[Unit]
BindsTo=sys-subsystem-net-devices-wlan0.device
After=sys-subsystem-net-devices-wlan0.device
[Install]
RequiredBy=sys-subsystem-net-devices-wlan0.device
[Service]
ExecStart=
ExecStart=/usr/libexec/iwd --interface wlan0 -d
and then running the following vendor utility command a handful of times:
wl -i wlan0 bus:disconnect 99
The command forces a firmware crash. brcmfmac will then destroy its
interfaces and wiphy before reloading the firmware and recreating
everything again. But in the mean time, systemd will send a SIGTERM to
iwd because of the BindsTo= above. From the logs, you can see that iwd
hangs around long enough to pick up the recreated station interface and
attempt an autoconnect before iwd_modules_exit() is called.
Hope that helps!
Kind regards,
Alvin

Certain module dependencies were missing, which could cause a crash on
exit under (very unlikely) circumstances.

So we manage to detect and setup the device, scan and start the connect in the 1
second grace period during shutdown? Impressive.
Can you try the patch I just sent out to the list and see if it fixes the crash?
I guess we could also add some logic to disable wiphy detection when we're
shutting down, but this is a pretty weird set of circumstances :)
Regards,

Thanks a lot for the patch. Sorry for the slow reply. But I tried it now
and it seems to do the job: after hundreds of cycles it didn't segfault
at all. Previously it was reproducible after 2-3 cycles. And I had a
look over the patch and it seems correct.
Do you intend to commit it to the upstream git tree?
Kind regards,
Alvin

Excellent, thanks for testing!

Yes, pushed out upstream now.
