From fd5c399c01ceb1bbede3ae8b0e1daaa7652a6fa1 Mon Sep 17 00:00:00 2001 From: Olof Sivertsson Date: Wed, 3 Jan 2018 10:35:13 +0100 Subject: [PATCH] proto: allow dumping protocol handlers without config_params When ubus invokes proto_dump_handlers, and a struct proto_handler has been added with a NULL config_params, a segmentation fault occurs. Avoid this segmentation fault by checking for a NULL config_params before further access.
