The current format for the .known_networks.freq file had a hidden
limitation of not being able to handle SSID's with some special
characters. Since the provisioning file path was used as the
group name the filename was limited to only characters supported
by l_settings groups, which conflicted with allowable SSID
characters.
Instead we can generate a unique UUID for each network and use
this as the group. For this particular case the group does not
really matter, so long as its unique. But we can utilize this unique
UUID for other purposes, including using it as a seed for changing
the MAC address per-connection in the future.
The .known_networks.freq file will now have the following format:
[<UUID>]
name=/path/to/provisioning/file
list= XXXX YYYY ZZZZ
The existing frequency syncing was done when IWD closes. Instead we
can sync as networks are connected to or promoted to known which
will keep the FS more up to date. This also allows hotspot networks
to use the known frequency file.
This API will sync the known frequencies of a network_info object
to disk. This will allow network to sync known frequencies as
known networks are added, rather that when IWD closes.
Since this will result in more frequent syncing that before, the
known_freqs settings pointer was moved globally in knownnetworks.c
as to only parse the file one time rather than on every sync.
Some of the EAP-PEAP server implementations seem to require a
cleartext ACK for the tunneled EAP-Success message similar to EAP-TLS
specification, instead of simply shutting down the tunnel like
EAP-PEAPv1 requires.
ACKing the tunneled EAP-Success seems also to work for implementations
which were relying on the tunnel close event.
create_dirs was dependent on the path ending in '/' to create the
full path. The hotspot code did not include a '/' at the end so
it was not getting created, which prevented the hotspot module
from initializing.
Station was building up the HS20 elements manually. Now we can
use this new API and let network take care of the complexity
of building network specific vendor IEs.
This op builds up the vendor IEs required for hotspot 2.0. The
version, and optionally the RC are provided in order to correctly
build the HS20 Indication Element and RC Selection element.
The HS20 module had its own getter for returning the matched roaming
consortium. Since we already have the network_info op for matching
we might as well return the matched RC rather than just a bool. This
allows the RC to be included in (Re)Association without the need for
a specific getter.
