From 477689788c59f62a32c9d76e44838aa22bab0b05 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 27 Dec 2013 18:44:21 +0200 Subject: [PATCH] WNM: Fix AP processing without wnm_oper driver callback hostapd_drv_wnm_oper() needs to indicate an error if the driver callback function is not implemented. Without this, the buf_len argument could have been left uninitialized which could result in crashing the process.
