[Bug 1781597] Re: [SRU] WoWLAN settings are not supported

[Brian Murray]

Hello Alfonso, or anyone else affected,

Accepted network-manager into cosmic-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/network-
manager/1.12.4-1ubuntu1.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-cosmic to verification-done-cosmic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-cosmic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

+ WoWLAN lets us wake up the system by sending wake packets over the wifi
  connection. This is something requested by some OEM projects, for bionic
  server images.
  
  NM 1.12 supports configuring this feature, so this can be achieved by
  backporting that support to 1.10 (bionic version). These are the MPs for
  cosmic and bionic:

  https://code.launchpad.net/~alfonsosanchezbeato/network-manager/+git/network-manager/+merge/349465
  
  [Test Case]
  
  First, the wifi card must support WoWLAN. This can be checked by running
  
  $ iw phy
  
  and searching for "WoWLAN support:" in the output. If it is supported,
  with the patch applied a connection configured with wowlan can be
  created with:
  
  $ sudo nmcli d wifi connect <ssid> password <password>
  $ sudo nmcli c modify <ssid> 802-11-wireless.wake-on-wlan 8
  $ sudo nmcli c down <ssid>
  $ sudo nmcli c up <ssid>
  
  We can check with 'iw' that WoWLAN is active for the connection:
  
  $ iw phy phy0 wowlan show
  WoWLAN is enabled:
-  * wake up on magic packet
+  * wake up on magic packet
  
  In this case we have configured the connection to wake up the system
  when a 'magic' packet is received. We can then suspend the system with
  
  $ sudo systemctl suspend
  
  And we should be able to wake the system from another device with the
  command
  
  $ sudo etherwake -i <wifi_iface> <destination_MAC_address>
  
  [Regression Potential]
  
  Although the patch is not especially small, it is a backport of changes
  that have been merged upstream, with very little modifications to make
  it compile in 1.10. It is also a rather isolated feature that should not
  conflict with existing ones. The feature will be activated only if
  configured from the command line, so the risk of regressions should be
  small. Note also that the patch will be removed as soon as Ubuntu moves
  to NM 1.12.

** Changed in: network-manager (Ubuntu Cosmic)
       Status: New => Fix Committed
