Hi folks.
Dariusz fix worked for me.
I reverted my config to failure mode -- while i was connected to the wifi, I
did not get an IP address.
Changed the wifi to use wpa-conf (so I had a network to do the upgrade).
Upgraded to the ppa
Changed the wifi back to using wpa-roam
ifdown / ifup -- all good
rebooted -- all good.
here is my network/interfaces:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface

iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#iface wlan0 inet dhcp
# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
===
Here is my wpa_supplicant.conf:
===
update_config=1
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
ssid="MySSID"
psk="MyPSK"
id_str="home"
}
===
@Robert: Just checking, but your wpa.conf file is actually named
wpa_supplicant.conf -- Yes??

Basically the same as yours. It's worth confirming the symptoms: for me
this setup was working fine until a recent apt-get upgrade. After that,
wireless appeared to come up but no address was assigned over DHCP. I
could get one by manually running "dhclient wlan1". It was apparent
looking at the logs that dhclient was not being run after the wireless
connection came up, and the PPA from Dariusz has dhclient running again.

Title:
wpa-roam broken by fix for ifupdown #1337873
Status in wpa package in Ubuntu:
Confirmed
Bug description:
[Impact]
* In some configurations recurrent ifup/down calls are broken due to
a false-positive recursion detection.
* In certain situations it leaves interfaces unconfigured (in this
case: WLAN interface connected to WiFi network, but dhcp fails).
[Test Case]
* Setup wpa-roam configuration based on what is in comment #6
* Wait until wpa_supplicant connects to a wifi network
* Run ifconfig to check if the WLAN interface received dhcp info
* Expected result: WLAN is fully configured according to dhcp settings
* Actual result: WLAN is connected to WiFi but not configured
[Regression Potential]
* Fixed upstream, fix present in Xenial.
* Debdiffs contain a backport of an upstream fix.
[Other Info]
* Original bug description:
The following versions of ifupdown introduced a recursion check using
"IFUPDOWN_" environment variables along with a new locking mechanism
for ifup (see #1337873):
0.7.47.2ubuntu4.2 (in Trusty)
0.7.54ubuntu1.1 (in Wily)
0.7.54ubuntu2 (in Xenial)
This recursion check breaks the wpa-roam feature of wpasupplicant,
preventing it from loading the logical interface specified by id_str
after associating with an AP. Specifically, after upgrading to one of
the above ifupdown versions, the '/sbin/ifup -v --force
"$WPA_IFACE=$WPA_LOGICAL_IFACE"' command run by wpa_action in
functions.sh fails with an "ifup: recursion detected for parent
interface wlan0 in post-up phase" error.
To fix the issue, functions.sh needs to run `unset
"IFDOWN_$WPA_IFACE"` before calling /sbin/ifup to prevent ifup from
detecting the recursion. The attached patch implements this change.

See bug #1545363 - my patch for that bug happens to remove the use of the ifstate file. However, fixing that does not solve the "ifup: recursion detected ..." issue. The environment variable still needs to be removed to fix the recursion issue. After thinking about it some more, I think it may make more sense to unset the variable in /etc/wpa_supplicant/ifupdown.sh rather than /etc/wpa_supplicant/functions.sh (so the variable is removed from the wpa_supplicant daemon's environment, rather than being removed each time wpa_action calls ifup or ifdown).

[Touch-packages] [Bug 1545302] Re: wpa-roam broken by fix for ifupdown #1337873
Paul, I think that the real cause here is that (by looking into debian/ifupdown/functions.sh) wpasupplicant depends on the previous single-file ifstate. Currently, for the sake of the locking mechanism, it has been split into an individual ifstate.$IFACE per interface, while wpasupplicant still checks for the state /run/network/ifstate. This leads to loosing track of aliases and misusing of the locking. I will work on fixing this for Ubuntu and Debian and will appreciate your help in testing it as soon as a hotfix is ready.

My configuration:
/etc/network/interfaces
auto wlan0
iface wlan0 inet manual
wpa-driver wext
wpa-roam /etc/wpa_supplicant/wpa.conf
wpa-roam-default-iface dhcp
iface dhcp inet dhcp
dns-nameservers 8.8.8.8 8.8.4.4
iface dhcp_dns
/etc/wpa_supplicant/wpa.conf

ssid="x"
priority=10
key_mgmt=WPA-PSK
psk="..."
id_str="dhcp_dns"
}
network={
ssid="y"
priority=9
key_mgmt=WPA-PSK
psk="..."
}
After connecting to either the x or y networks, wpa_supplicant calls
`wpa_action connect` which calls `ifup wlan0=dhcp_dns` or `ifup
wlan0=dhcp`, which fails with "ifup: recursion detected for parent
interface wlan0 in post-up phase". Therefore, dhclient is never run, so
wlan0 never gets an IP address.
Note that the wpa_supplicant daemon is started by the /etc/network/if-
up.d/wpasupplicant script, and it inherits the environment from `ifup
wlan0` (including the environment variable used to detect recursion).
`wpa_action connect` then inherits the environment from wpa_supplicant,
and `ifup wlan0=dhcp` inherits it from wpa_action, hence the error from
ifup.
I understand that this variable is meant to avoid certain race
conditions, but I don't believe the type of race condition reported in
bug #1337873 is applicable to this situation. Because wpa_supplicant is
started by ifup itself (and not a boot script), there is no way for the
`ifup wlan0` and `ifup wlan0=dhcp` to be called out of order, so there
is no chance of a race condition. However, maybe I'm missing something
here. Could you explain how the wpa-roam implementation could play
along with ifupdown given that it is started by ifup itself and needs to
call ifup to reconfigure the interface?

To fix the issue, functions.sh needs to run `unset
"IFDOWN_$WPA_IFACE"` before calling /sbin/ifup to prevent ifup from
detecting the recursion. The attached patch implements this change.

[Touch-packages] [Bug 1545302] Re: wpa-roam broken by fix for ifupdown #1337873
Hello Paul, The locking mechanism was implemented to avoid race conditions in ifupdown (such as the one reported as bug #1337873). Unsetting the variable may lead to unexpected consequences. I belive a proper solution would be to modify wpa-roam implementation to play along with ifupdown. Could you please share your configuration? I tried reproducing it but was unable to do so with the simplest wpa-roam config I checked (ifup brings the interface up as expected with ifupdown 0.8.10ubuntu1 on Xenial. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to wpa in Ubuntu. https://bugs.launchpad.net/bugs/1545302 Title: wpa-roam broken by fix for ifupdown #1337873 Status in wpa package in Ubuntu: Confirmed Bug description: The following versions of ifupdown introduced a recursion check using "IFUPDOWN_" environment variables along with a new locking mechanism for ifup (see #1337873): 0.7.47.2ubuntu4.2 (in Trusty) 0.7.54ubuntu1.1 (in Wily) 0.7.54ubuntu2 (in Xenial) This recursion check breaks the wpa-roam feature of wpasupplicant, preventing it from loading the logical interface specified by id_str after associating with an AP.
