From cee9fcdb7350911f474544189817d25fd4070111 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Wed, 3 Apr 2024 14:32:08 -0500 Subject: [PATCH] wifi-scripts: fix creation of IBSS in legacy (non-HT) mode When an IBBS interface is configured for IBSS legacy mode, wdev.htmode is empty. This is empty string results in an empty positional argument to the "ibbs join" command, for example: iw dev phy0-ibss0 ibss join crymesh 2412 '' fixed-freq beacon-interval 100 This empty argument is interpreted as an invalid HT mode by 'iw', causing the entire command to fail and print a "usage" message: daemon.notice netifd: radio0 (4527): Usage: iw [options] \ dev ibss join ... Although nobody will ever need more than 640K of IBSS, explicitly use "NOHT" if an HT mode is not given. This fixes the problem.
