Rather than using timespec directly, ELL has a convenient API
to get the elapsed microseconds as a uint64_t. This can then
be used with the other l_time_ APIs for comparison.
This patch removes timespec from network_info and updates
to use l_time_* API's for sorting.
These operations will allow the hotspot module to implement
matching HESSID, Roaming Consortium, and NAI realms. This offloads
the matching details into the hotspot module.
This way resolve_remove can be called once per interface and
remove IPv4 and IPv6 addresses at once.
In addition, this allows to remove the IP addresses and DNS
servers within the same main loop cycle. This will allow iwd
to make an attempt to remove the DNS servers on shutdown of iwd.
These two API's have been added to allow hotspot to add its
own networks to the known network list. This will allow any
added networks to behave exactly like they do now, including
all the dbus and watchlist functionality.
The known network APIs all revolved around the ssid/security matching
to do any operations on the provisioning file. In the near future
hotspot provisioning files (managed by hotspot.c) will be incorporated
into the known network list. Since these hotspot files do not use the
ssid as the file name hotspot.c will need other ways of matching.
This patch adds network_info_ops to the network object. This ops
structure will hold function pointers which operate on network_info
rather than ssid/security. This will allow hotspot and known networks
to both register their own operation routines.
For now open, touch, sync, remove, free, and get_path were added.
Wrappers were added for accessing these operations outside of
knownnetworks.c.
Isolate the known_frequency queue management to a function and place
that function in knownnetworks.c where it now belongs. Since we no
longer have network_info objects for unknown networks, only frequencies
for known networks are tracked
networks queue was intended to share basic network information between
multiple adapters running simultaneously. The network_info object was
also serving double duty to carry known network information. This made
things overly complicated and really didn't result in much savings.
This setup also made managing hotspot networks challenging as we would
have ended up with multiple network_info objects for each known hotspot
network.
So get rid of the networks queue and the is_known bit from the
network_info structure.
network_find_rank_index was used to find the offset of the selected
network_info among known networks so as to compute a modifier based on
the rankmod table. Instead of using known_networks_foreach for this,
moove it to knownnetworks.c where it can be coded and optimized
separately.
For now provide a simple for loop implementation.
