From e410ef838959c0d7cd9a6c0a13d5f2ca2b03c077 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Thu, 6 May 2021 01:53:49 +0200 Subject: [PATCH] hostapd: wolfssl: add RNG to EC key Since upstream commit 6467de5a8840 ("Randomize z ordinates in scalar mult when timing resistant") WolfSSL requires a RNG for the EC key when built hardened which is the default. Set the RNG for the EC key to fix connections for OWE clients.
