Author: avos Date: Mon Jan 21 04:50:56 2019 New Revision: 343249 URL: https://svnweb.freebsd.org/changeset/base/343249 Log: Fix duplicate wpa_supplicant(8) / hostapd(8) startup with devd(8) Do not invoke 'wlan_up' function from devd(8) on interface creation event (an example to create such event: 'ifconfig wlan0 create wlandev rtwn0'); they're typically produced during 'service netif (re)start' and result in duplicate interface initialization. From the user side if WPA option is used, this result in messages like: - /etc/rc.d/wpa_supplicant: WARNING: failed to start wpa_supplicant or - wpa_supplicant already running? (pid=xxxx). (for HOSTAP interfaces this race may result in startup failure). As a side effect, wpa_supplicant(8) / hostapd(8) will not be invoked when new wlan(4) interface is created manually and corresponding configuration for it is present in rc.conf(5). This change does not affect device attach / removal events.
