From 3c58df7ae7b7467e30f2aa47d2bbecc2d52abb21 Mon Sep 17 00:00:00 2001 From: Ilan Peer Date: Mon, 29 Feb 2016 14:29:58 +0200 Subject: [PATCH] wpa_cli: Support running action script on global control interface In case wpa_cli is started with an option to execute an action script, but no interface is specified, wpa_cli might crash in wpa_cli_exec() if arg1 == NULL. Fix this be setting arg1 = "global".
