[Bug 1320752] Re: MAC Spoofing / Cloning for WiFi is broken in Trusty 14.04 / 14.10 and all others including Mint 17

 

Just encountered this on a Lenovo laptop with the built in Intel WiFi,
before I found this bug I discovered that if you bring the interface
down change the mac address and bring it back up again before network
manager starts, and then restart network manager some time after the
user logs in, it will connect successfully...  not sure why.

Title:
  MAC Spoofing / Cloning for WiFi  is broken in Trusty 14.04 / 14.10 and
  all others including Mint 17

Status in network-manager package in Ubuntu:
  Confirmed
Status in wpasupplicant package in Ubuntu:
  Confirmed

Bug description:
  **SHORT OVERVIEW**

  "Cloned MAC Address" feature doesn't work with any USB WiFi adapters
  in 14.04, 14.10, Mint 17 and likely all others based on Ubuntu.

  It worked under 13.10 and was broken from day one in 14.04+.
  This is not an upgrade issue, i did a clean install to test.
  Atheros, Realtek, Ralink adapters tested, this has nothing to do with the driver type.

  The only symptoms are WiFi not connecting and the following dmesg
  output:

  [  214.296350] wlan0: authenticate with 98:fc:11:f2:f7:43
  [  214.305098] wlan0: send auth to 98:fc:11:f2:f7:43 (try 1/3)
  [  214.307421] wlan0: authenticated
  [  219.367559] wlan0: deauthenticating from 98:fc:11:f2:f7:43 by local choice (reason=3)
  ------------------------------------------------------------------------
  **TEMP SOLUTION***

  This bug is caused by wpasupplicant (2.1-0ubuntu1.1) in Trusty,
  network-manager is not the culprit.

  I quick fix is to downgrade wpasupplicant to the Saucy version,
  wpasupplicant (1.0-3ubuntu2). This is relatively easy and doesn't seem
  to affect anything else.

  ------------------------------------------------------------------------

  Original bug report info:

  after setting the mac to change in networkmanager i try to connect yet it never will, when looking at the logs it says it got disconnected by local choice (reason 3), it appeared it was because the mac wasnt effectively changed but then again i tried to do so disabling network-manager -> macchanger -m -> enabling network-manager, i checked with ifconfig if the mac has changed and it did however the result was the same
  maybe its because of this http://people.canonical.com/~ubuntu-security/cve/2013/CVE-2013-4579.html?

  **UPDATE**

  now works doing the macchanger procedure, directly from network-
  manager it doesnt
