There appears to be a bit of a chicken-n-egg problem with "wpa-roam"
type interfaces, and any other type of interface which need ifup
before a carrier can be detected:
"/etc/init.d/networking start" will only call ifup on hotplug class
interfaces with a carrier.
A "wpa-roam" type interface will not be able to detect a carrier
until wpa_supplicaant has been started, which is supposed to happen
in the pre-up phase. But there won't be any pre-up phase unless
ifup is called... catch 22.
This is the relevant part if my /etc/network/interfaces:
# use wpa_action to control this interface
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
# 'default' is used by wpa_cli as the fallback mapping target
iface default inet dhcp
Note that the udev hotplug script /lib/udev/ifupdown-hotplug works
fine - unconditionally calling ifup on any new hotplug interface. So
"hotplugging" wlan0 after the system is up will bring up the interface
and start wpa_supplicant.
The problem lies in the hotplug fallback code in /etc/init.d/networking,
which AFAIU is supposed to catch interfaces hotplugged/detected *before*
the system was fully operational. It makes ifup_hotplug depend on carrier
by testing for
[ "$(cat /sys/class/net/$link/operstate)" = up ]
This code has been like that "forever", and I cannot explain why it
suddenly has become a problem. I assume this might be related to udevadm
"settle" support, or some other unrelated boot process change. The main
point is that this code now has become a problem by preventing wlan
interfaces from automatically coming up on boot.
The simple attached patch fixes the problem for me. But I must admit
that I do not understand the intentions of the original code. It seems
completely illogical to avoid ifup unless the link is up, but I assume
there is a reason this was found necessary. In any case, I don't think
that reason can be valid anymore since the /lib/udev/ifupdown-hotplug
behaves differently.
(yes, I know I should probably give up and use networkd or whatever, but
FWIW the simple patch here does allow my to continue using my existin
ifupdown+wpa_supplicant config)
