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.
