From 3ee767086d306f8095b7301262b0fe053a0b9f50 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 5 Dec 2019 21:17:58 +0100 Subject: [PATCH] mac80211: don't call md5sum on non-existing file If no AP is configured, hostapd-${phy}.conf is not being created, hence md5sum fails and causes log pollution: netifd: radio1 (3183): md5sum: can't open '/var/run/hostapd-phy1.conf': No such file or directoy Hence make sure the file exists when calling md5sum.
