--interfaces (-i) tells iwd which interfaces to manage. If the option
is ommitted, all interfaces will be managed.
--nointerfaces (-I) tells iwd which interfaces to blacklist. If the
option is ommitted, no interfaces will be blacklisted.
When setting operstate to dormant or down, give it a callback for debug
purposes. It looks like that operstate down message does not have a
chance to go out currently.
knownnetworks.c/.h implements the KnownNetworks interface and loads the
known networks from storage on startup. The list of all the networks
including information on whether a network is known is managed in
network.c to avoid having two separate lists of network_info structures
and keeping them in sync. That turns out to be difficult because the
network.c list is sorted by connected_time and connected_time changes
can be triggered in both network.c or knownnetworks.c. Both can also
trigger a network_info to be removed completely.
network_info gets a is_known flag that is used for the
GetOrderedNetworks tracking and to implement the KnownNetworks
interface - loading of the list of known networks on startup and
forgetting networks.
For simplicity and future use (possibly performance), every struct network
gets a pointer to a network_info structure, there's one network_info for
every network being by any interface, not only known networks. The SSID
and security type information is removed from struct network because the
network_info holds that information.
network_info also gets a seen_count field to count how many references
from network.info fields it has, so as to fix the removal of
network_info structures. Previously, once they were added to the
networks list, they'd stay there forever possibly skewing the network
ranking results.
This also fixed the network ranking used by GetOrderedNetwork which
wasn't working due to a missing assignment of *index in
network_find_info also triggering valgrind alerts.
The eapol state machine parameters are now built inside device.c when
the network connection is attempted. The reason is that the device
object knows about network settings, wiphy constraints and should
contain the main 'management' logic.
netdev now manages the actual low-level process of building association
messages, detecting authentication events, etc.
Keep an updated sorted list of networks in addition to the "networks"
hashmap. The list can be queried through the GetOrderedNetworks dbus
method.
We also take advantage of that list to get rid of a single
l_hashmap_foreach in new_scan_results.
A function that calculates a new rank type to order all networks
currently seen by a netdev. The order is designed for displaying the
list to user so that the networks most likely to be wanted by the user
are first on the list.
