Problems attempting to use ad-hoc mode, link state remains dormant
by Diego Santa Cruz
Hello,
I am trying to establish an ad-hoc connection between two Linux devices using iwd but so far I have not had any success without manual intervention. In short the link state remains dormant and no packets can be sent.
I succeeded to do it manually with iw inspiring me from https://wiki.lm-technologies.com/linux-wifi-ad-hoc-mode/. I did the following on each of the devices (iwd was not running).
* iw phy phy0 interface add ibs0 type ibss
* ip link set ibs0 up
* iw dev ibs0 ibss join ibstest 2437
After a few seconds the two devices connected and "iw dev ibs0 link" showed (same MAC address on both)
Joined IBSS 86:ac:e8:60:15:f3 (on ibs0)
SSID: ibstest
freq: 2437
And "ip link show dev ibs0" shows
5: ibs0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 3c:6a:a7:51:6d:dd brd ff:ff:ff:ff:ff:ff
And I can successfully ping the local-link IPv6 address of the other device.
With iwd I do the following to establish ad-hoc networking.
* Reboot to start with a clean state
* Start iwd
* iwctl device wlan0 set-property Mode ad-hoc
* iwctl ad-hoc wlan0 start_open ibstest
A few seconds later the two devices do connect, I see the a "new Station" message from one of the iwd, and "iw dev wlan0 link" shows the same MAC address on both devices, so as far as I understand they are joined.
However, "ip link show dev wlan0" shows "NO-CARRIER" on both devices with state DORMANT and mode DORMANT.
5: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DORMANT mode DORMANT group default qlen 1000
link/ether 34:e1:2d:24:03:42 brd ff:ff:ff:ff:ff:ff
When doing it manually with iw the state was UP and the mode DEFAULT, so I manually changed the state with "ip link set wlan0 state up". After that "ip link" no longer shows NO-CARRIER and pings worked. Changing the mode was not necessary.
Is there something that I am missing? Or maybe something which is missing in iwd in adhoc mode?
One of the devices is using an Intel Wireless AC 9260 and the other one an Intel Wireless 8265 / 8275.
Thanks,
Diego

[PATCH 1/3] client: fix ad-hoc start_open DBus method name
by Diego Santa Cruz
Doing 'ad-hoc <wlan> start_open <"network name">' returned a
"No matching method found" error because start_open called
net.connman.iwd.AdHoc.Start instead of net.connman.iwd.AdHoc.StartOpen.

Possible MFP problem

I noticed in debug log that the first difference between this new router and tethered mobile phone is this:src/netdev.c:netdev_set_igtk() 4
So being misguided and industrious I commented out the callback setting for IGTK at:https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/src/hands...
which works around the problem for me.I reverted that patch and created /etc/iwd/main.conf with:[General]
ManagementFrameProtection=0
which works but with the caveat that I now have to manually do iwctl connect and type the password in.
I attached the pcap and screen capture at the time of the failed connection attempt (unfortunately the pcap seems to be missing events that are on screen which is why I include both).
Please let me know if any more information is needed. Any help greatly appreciated.
many thankscheersalbert
ps. fwiw wpa_supplicant works fine, but I am not keen to use it.

[PATCH] test-runner: fix segfault running with --log non-root
by James Prestwood
When running test-runner as non-root the environment variables
SUDO_GID/SUDO_UID were unset, causing atoi to segfault. This replaces
atoi with strtol, and checks the existance of SUDO_GID/SUDO_UID
before trying to turn it into an integer. This patch also allows
the uid/gid to be read from the user if running as non-root.
Note: running as non-root does require the users permissions to be
setup properly. Directories and files are created when running with
logging, so if the user running test-runner does not have these
permissions the creation of these files will fail.
