From 685ea2f60c2fc09aac83733fcb8a7c8505ebaca4 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 10 Dec 2015 12:56:06 +0200 Subject: [PATCH] wpa_cli: Send ALL_STA command to the correct interface wpa_ctrl_command_sta(), called by the "ALL_STA" handler, didn't consider ifname_prefix, resulting in various commands being sent to the global control interface, rather than the specified interface when IFNAME= prefix was used. This in turn caused the unexpected "UNKNOWN COMMAND" result be considered as valid station, resulting in infinite loop while trying to get all stations. Fix it by considering ifname_prefix, similarly to _wpa_ctrl_command().
