95f1fb1663 manager: dump wiphy/iface on NEW_WIPHY
A NEW_WIPHY event may not always contain all the information about a
given phy, but GET_WIPHY will. In order to get everything we must
mimic the behavior done during initalization and dump both wiphy
and interfaces when a NEW_WIPHY comes in.

Now, any NEW_WIPHY event will initialize a wiphy, but then do a
GET_WIPHY/GET_INTERFACE to obtain all the information. Because of
this we can ignore any NEW_INTERFACE notifications since we are
dumping the interface anyways.

Once some kernel changes get merged we wont need to do this anymore
so long as the 'full' NEW_WIPHY feature is supported.

7a9891dbef wsc: store plain text passphrase if available
If the AP sent us the plain passphrase we can now store that rather
than generating the PSK. This will allow WPA3 to work properly when
WPA3 + WSC is implemented.

2c14e73f82 network: add network_set_passphrase
This lets other modules (like WSC) to set a plain text passphrase
as opposed to only allowing a PSK to be set. network_get_psk was
also updated to generate a PSK on-the-fly if required. Since WPA3
requires the raw passphrase to work, it makes sense to just store
the passphrase if we have it.

a8187468b5 station: optimize roam scanning

66346712e6 knownnetworks: make frequencies/UUID forgettable
Since the UUID was being generated purely on the file path, it
would never change for a given network (unless the SSID/name changed).
In the future we would like to use this unique UUID to generate a
MAC per-SSID, and if that network is forgotten we also want the UUID
to change next time the network is connected to.

Rather than only using the file path, the mtime can also be fed into
the UUID generation. Since the mtime would be changed after forgetting
and re-adding a known network we will get a new UUID.

Now, whenever a known network is removed, we lookup the UUID we have
in network_info and remove that entry in the settings file and
sync the frequency file.

f57b73898b knownnetwork: track/optimize UUID for known networks
The UUID was being generated every time we synced which is wasteful.
Instead we can track the UUID inside network_info and only generate
it once when needed.

Two new network_info APIs were added:
network_info_set_uuid
network_info_get_uuid

The setter is used when the frequency file is loaded. If a valid UUID
is found in the frequency file this UUID is set and used.

network_info_get_uuid will not just get the UUID, but actually generate
it if one has not been set yet. This will allow other modules to
get/generate the UUID if one has no been loaded from the frequency
file.

8d3b065022 wiphy: fix bits in extended capabilities
The extended capability bits were not being set properly inside
wiphy. Since we build the IE after the wiphy dump the first 2
bytes are the IE type and length. The way we were setting the bits
did not take this into account and were actually setting the
completely wrong bits.

ef209c305b knownnetworks: make known frequencies its own module
The known frequency file was being loaded at the end of the known
networks initialization routine. This allowed all known networks
to be properly loaded, but since hotspot depends on known networks,
its initalization would be run afterwards meaning the frequency
loading would not have been finding any hotspot networks.

To fix this a new module was added inside known networks which
depends on hotspot. This means that first known networks will
initialize, then hotspot, then the frequency file would be loaded.

4eaf93d26a knownnetworks: rework known frequencies
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

f5db4bfea8 network: sync frequencies per-network
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

9ed5fba57b knownnetwork: add known_network_frequency_sync
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.

0db5f59d07 peap: Send cleartext ACK to tunneled EAP-Success
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.

af46cc0ed2 knownnetworks: get matched RC on match_roaming_consortium
The HS20 module had its own getter for returning the matched roaming

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.

8500b60b13 network: fix issue with WSC not connecting
After wsc_store_credentials, wsc_try_credentials is called which
sets the PSK obtained via the protocol. After the known network
refactor network_settings_load was changed to depend on the
network_info->open() call. Since there is no known network for
this initial WSC connection this always fails and the PSK is not
set into the network object (and the connection is failed).

In this case if network_settings_load fails we can just create
an empty settings object to be filled later.

one major difference; it no longer can be used to create new known

a3a48da542 station: allow autoconnect to hotspot networks
Since hotspot networks may require ANQP the autoconnect loop needed to
be delayed until after the ANQP results came back and the network
objects were updated. If there are hotspot networks in range ANQP will
be performed and once complete autoconnect will begin for all networks
including hotspots. If no hotspots are in range autoconnect will
proceed as it always has.

Note: Assuming hotspots are in range this will introduce some delay
in autoconnecting to any network since ANQP must come back. The full
plan is to intellegently decide when and when not to do ANQP in order
to minimize delays but since ANQP is disabled by default the behavior
introduced with this patch is acceptable.

b3881b84c1 eapol: Propagate noencrypt and use it
We were not using or taking into account the noencrypt flag obtained
from the kernel via CONTROL_PORT events.  For the most part this still
worked as the kernel would never include NO_ENCRYPT flag (due to a bug).
However, this was actually incorrect and led to loss of synchronization
between the AP and STA 4-Way handshake state machines when certain
packets were lost and had to be re-transmitted.

fc4685abec eap-tls: Add ServerDomainMask config option
Allow users to provide a glob string that the contents of the server
certificate's subject DN should be matched against as a primitive
protection against rogue APs using certificates purchased from
commercial CAs trusted by the client.  If the network uses an AP
certificate emitted by a commerical CA and the clients are configured
to trust those CAs so that the client configurations don't have to be
updated when the AP renews its certificate, this new option can be used
to check if the CN in the AP certificate's DN matches the known domain
name.  This logic assumes that the commercial CAs provide enough
assurance that only the owner of the domain can buy a certificate with
that domain in the CN field.

The format of this option is similar to apple's TLSTrustedServerNames
and wpa_supplicant's domain_match/domain_suffix_match format, the exact
syntax is documented in ell/tls.c.

20887dfe1a wiphy: explicitly set extended capability bits
Some capability bits are required by the spec to be set for
probe requests for certain features (HS20, FILS, FT). Currently
these features work as-is, but depending on the hardware we may
be in violation of the spec if we assume the correct bits are
set when we get the wiphy dump.

Just to be safe we can explicity set these capability bits.

There are also two ways the kernel exposes these capabilities.
Per-type or globally. The hardware may expose one, or both of
these capability arrays. To combat this we are now always
creating a per-type capability array for stations. If the
wiphy dump has not produced a per-type capability array we
now create one based off the global capability array. That
way we can always assume there is a capability array for a
station iftype.

313553aadd hotspot: require 'Name' value in provisioning file
In order to implement get_name/get_type we need some value for the name
of the hotspot network. For simplicity we now require a 'Name' value
be provided inside the hotspot provisioning file. Eventually this may
change (e.g. obtained via ANQP).

6ff86abb41 knownnetworks: use l_path_get_mtime
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.

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.

28f484ddb8 network: knownnetworks: introduce network_info_ops
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.
