Daniel,
I built the kernel/modules (I am on Arch on an RPi and the kernel I am
using is 4.19.114) and tried to diagnose the ap mode problem with nlmon and
get this, though I am sure I am doing it wrong:
# modprobe nlmon
# ip link add name nlmon type nlmon
# ip link set dev nlmon allmulticast on
# ip link set dev nlmon up
# tcpdump -i nlmon -w trace-file.pcap
tcpdump: listening on nlmon, link-type NETLINK (Linux netlink), capture
size 262144 bytes
^C158 packets captured
163 packets received by filter
0 packets dropped by kernel
# iwmon -r trace-file.pcap
Wireless monitor ver 1.6
Invalid packet format
In another window, I did this to see what was going on:
~# connmanctl tether wifi on myssid password
Wifi SSID set
Wifi passphrase set
Enabled tethering for wifi
# ip addr

I tried to connect to this AP with my Win10 laptop and get the response:
"Can't connect to this network". My Arch Laptop likewise will not connect.
Now, when I run iwd -d, I get this:
# /usr/lib/iwd/iwd -d
No Diffie-Hellman support found, WPS will not be available
No asymmetric key support found.
TLS based WPA-Enterprise authentication methods will not function.
Kernel 4.20+ is required for this feature.
The following options are missing in the kernel:
CONFIG_ASYMMETRIC_KEY_TYPE
CONFIG_KEY_DH_OPERATIONS
CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE
CONFIG_PKCS7_MESSAGE_PARSER
CONFIG_X509_CERTIFICATE_PARSER

strange thing is that most of those features are built in the kernel. My
kernel is 4.19.114 and the config specifies:
# CONFIG_CRYPTO_HW is not set
CONFIG_ASYMMETRIC_KEY_TYPE=y
CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE=y
CONFIG_X509_CERTIFICATE_PARSER=y
CONFIG_PKCS7_MESSAGE_PARSER=y
I am currently re-building the kernel with:
CONFIG_KEY_DH_OPERATIONS=y
as it was previously not set.
There does not seem to be any reference to PKCS8 for this kernel.
Thanks!
Keith

The RPi kernel has no support for nlmon enabled. If you want to debug this =
you<br>
propably need to compile your own RPi kernel with nlmon enabled.<br>

--wifi=3Diwd_agent is wrong. If you want iwd support you need to define thi=

at compile time only:<br>
<br>
=C2=A0 =C2=A0./configure --enable-iwd --disable-wifi<br>

which adds the iwd plugin and disables the wpa_supplicant plugin. But I don=

discover iwd. Just make sure wpa_supplicant is not running. With the above<=

Did you try to run iwd with debug enabled 'iwd -d'? Maybe there is =
more<br>
info. And if there isn't any clue, the best way forward is to get<br>
nlmon running and provide the information the iwd developers. From what I<b=
r>
see ConnMan is talking to iwd and setups the AP mode.<br>

I don't know but I would suggest to address this in the same go when yo=
u build<br>
a new kernel with nlmon support.<br>
