A (very) brief tour of the OLPC 802.11s device class in NM r3246

[Michael Stone]

Sjoerd and I started dissecting our NM-0.6 divergence so that we can
begin porting that necessary pieces of that divergence to NM-0.7.
Several highlights from our reading of two important files follow.
NM-specific terminology is /emphasized/.

nm-device-802-11-mesh-olpc.c [1] contains:

  * A nice description of the state machine currently used to decide
    change network associations. 
        http://tinyurl.com/5xnxgw

  * The flag-file MESH_STEP_FILE (/etc/NetworkManager/mesh-step)
    which can be used to alter the initial state of the aforementioned
    connectivity state machine.
        http://tinyurl.com/4ltm2u

  * The callbacks and setup/teardown logic on lines 536-661 which sync
    the 'scanning' flag between the /mesh device/ (a.k.a. the msh0
    network interface) and its /companion (wireless) device/.
        http://tinyurl.com/5ydns6

  * Hoary netlink socket code (perhaps duplicating functionality of
    iwconfig?) in the second quarter of the file.
        http://tinyurl.com/427fxg

  * Hoary /mpp/ (mesh portal point) - http://tinyurl.com/4yxbyr
          /aipd/ (avahi-autoipd)    - http://tinyurl.com/43kygw   and
          device association logic  - http://tinyurl.com/4fstfh
    in the second half of the file.

  * The init method of the Mesh Device gobject class, showing off all
    the Device methods we have overriden.
        http://tinyurl.com/537awj

nm-dbus-nm.c [2] contains:

  * The construction and implemenation of the D-Bus interface used by
    Sugar for /device activation/ (associating with networks) radio
    discipline.

More details to come,
