Supply the following if possible:

  • Device problem occurs on
    tested on VoCore2, Netgear wndr3700, SamKnows WhiteBox8

  • Software versions of OpenWrt/LEDE release, packages, etc.
    OpenWrt master branch as of d22c175

  • Steps to reproduce

  • compile OpenWrt with "wpad-wolfssl" instead of "wpad"

  • setup WPA3 secured 802.11s wireless

  • get attached kernel call trace

I updated wolfssl from 4.1.0 to 4.2.0 (0001-wolfssl-update-to-4.2.0.patch) and tested again. Still the same.

If there is another 802.11s partner in reach I get the output in command-line-output.txt
If there is no other 802.11s partner in reach no error is shown.

My /etc/config/wireless is attached. On one of the two VoCore2 I set network.lan.ipaddr='192.168.1.2'. I have not changed anything else.

I tested with wpad-openssl on one VoCore2 and wpad-wolfssl on the other. wpad-openssl shows WPA3 as encryption while wpad-wolfssl tells "none". Unencrypted mesh is working between both devices.
