[OpenWrt-Devel] hostap commit 6c9543fcb breaks MESH-SAE with wolfssl

[Daniel Golle]

Hi!

After hours of bisecting which change between hostapd_2_8 and
hostapd_2_9 broke SAE in mesh mode with WolfSSL we got a result:

> commit 6c9543fcb7962e26c2a91c43089abe171d073b44
> Author: Jouni Malinen <jouni at codeaurora.org>
> Date:   Thu Apr 25 20:18:27 2019 +0300
> 
> Share common SAE and EAP-pwd functionality: random qr/qnr creation
> 
> Use a shared helper function to create random qr/qnr values.
> 
> Signed-off-by: Jouni Malinen <jouni at codeaurora.org>

While when building against OpenSSL, things keep working also after
the above commit, when building against WolfSSL, the node hangs in
LISTEN state for a long time and then ends up BLOCKED.
I've tried with WolfSSL 3.14.4 and WolfSSL 4.3.0-stable-1 with
identical results.
Going back to commit 2b84ca4dd
("Share common SAE and EAP-pwd functionality: suitable groups") makes
things working again also with WolfSSL.

On first sight there seems nothing wrong with that commit to me, but
apparently it does break things :(

Any ideas helping to fix this would be highly appreciated!


Best regards


Daniel
