Description James 2014-05-07 14:54:20 UTC 
Description of problem:

With a hidden wireless network, after boot NetworkManager runs at full processor speed prior to a graphical login. It also clogs the system log with messages, including messages of the type "should not be reached":

May  7 17:29:59 localhost NetworkManager[842]: file devices/nm-device.c: line 7175 (nm_device_add_pending_action): should not be reached
May  7 17:29:59 localhost NetworkManager[842]: <warn> (wlp3s0): remove_pending_action (2): 'autoactivate' never added
May  7 17:29:59 localhost NetworkManager[842]: file devices/nm-device.c: line 7226 (nm_device_remove_pending_action): should not be reached

Version-Release number of selected component (if applicable):

Up-to-date versions of all related packages. In particular NetworkManager version 0.9.9.0.

How reproducible:
Unknown, but I would try the list given below.

Steps to Reproduce:
1. Install only a hidden wireless network.
2. Do not perform a graphical login at boot.
3. Run 'top' to see that NetworkManager is eating all cpu time.
4. Also notice that your cpu fan is running at full speed.

Actual results:


Expected results:


Additional info:

Highlights from /var/log/messages; these are repeated a LARGE number of times:

Interface wlp3s0 is available, at least after graphical login.

I can reproduce this by killing nm-applet (not using gnome-shell) and trying to activate a Wi-Fi connection without secrets. NM enters into endless looping retrying the connection (even if it failed due to missing secrets).

[PATCH] f20: bunch of patches rebased from upstream master

I took bunch of patches from upstream that are related to auto-connecting and fixes couple of some bugs. Unfortunately, some of the patches are related to each other. So maybe I ended up with too many of them. It seems working for me, but I'd appreciate testing.
Comment 3 Jirka Klimes 2014-05-20 16:29:47 UTC 
I have made a scratch build:
http://koji.fedoraproject.org/koji/taskinfo?taskID=6867349

Please would you test (not only the issue, but also other operations for regressions).

Hm... this is quite hard to review. Would be nice to have individual cherry-picks of the upstream commits

[PATCH v2] f20: bunch of patches rebased from upstream master

This obsoletes the patch attachment 897663 [details] (comment 2).

This patch is identical to the previous, only fixed up the format so that it can be applied with git-am.
Comment 6 Thomas Haller 2014-05-27 14:40:36 UTC 
The backported patches look good to me.
