65109ec46d wiphy: Drop wiphy creation logic 2019-04-11 11:20:04 -05:00

530a449337 manager: Add new file for wiphy/interface management
Add manager.c, a new file where the wiphy and interface creation/removal
will be handled and interface use policies will be implemented.  Since
not all kernel-side nl80211 interfaces are tied to kernel-side netdevs,
netdev.c can't manage all of the interfaces that we will be using, so
the logic is being moved to a common place where all interfaces on a
wiphy will be managed according to the policy, device support for things
like P2P and user enabling/disabling/connecting with P2P which require
interfaces to be dynamically added and removed.

4a969294f7 wiphy: Add wiphy_create/wiphy_destroy API
Add wiphy_create, wiphy_update_from_genl and wiphy_destroy that together
will let a new file command the wiphy creation, updates and deletion
with the same functionality the current config notification handler
implements in wiphy.c.

c06754a978 wiphy: Drop name_len from wiphy_parse_id_and_name
As mentioned in code comments the name is NUL-terminated so there's no
need to return the length path, which was ignored in some occasions
anyway.  Consistently treat it as NUL-terminated but also validate.

8f910518c4 netdev: Make netdev_create_from_genl, netdev_destroy public
Make netdev_create_from_genl public and change signature to return the
created netdev or NULL.  Also add netdev_destroy that destroys and
unregisters the created netdevs.  Both will be used to move the
whole interface management to a new file.

d081f5f871 client: Switch known-networks cmd pattern to common scheme
Switch the command pattern to match the common command scheme
where the entity name (network name) follows the command family name:
From
	known-network forget <network name>
To
	known-network <network name> forget

In addition, it extracts the network match by name logic into its
own function for the further reusability. In the case of ambiguity
between the network objects with the same SSID but different security
types the logic asks to specify the security type in addition
to the network name as follows:
	known-network <network name.security> forget

81fc6a687e handshake: add flag for FILS support
The handshake_state only holds a single AKM value. FILS depends on the AP
supporting EAP as well as FILS. The first time IWD connects, it will do a
full EAP auth. Subsequent connections (assuming FILS is supported) will use
FILS. But if the AP does not support FILS there is no reason to cache the
ERP keys.

This adds the supp_fils to the handshake_state. Now, station.c can set this
flag while building the handshake. This flag can later be checked when
caching the ERP keys.

5df84a6933 erpcache: implementation for ERP key cache
This allows IWD to cache ERP keys after a full EAP run. Caching
allows IWD to quickly connect to the network later on using ERP or
FILS.

The cache will contain the EAP Identity, Session ID, EMSK, SSID and
optionally the ERP domain. For the time being, the cache entry
lifetimes are hard coded to 24 hours. Eventually the cache should
be written to disk to allow ERP/FILS to work after a reboot or
IWD restart.

875c6f27e7 eap: enforce max identity lengths
EAP identites are recommended to follow RFC 4282 (The Network Access
Identifier). This RFC recommends a maximum NAI length of 253 octets.
It also mentions that RADIUS is only able to support NAIs of 253
octets.

Because of this, IWD should not allow EAP identities larger than 253
bytes. This change adds a check in eap_load_settings to verify the
identity does not exceed this limit.

8f9ed66bdd mpdu: Rework validate_mgmt_ies
802.11 mandates that IEs inside management frames are presented in a
given order.  However, in the real world, many APs seem to ignore the
rules and send their IEs in seemingly arbitrary order, especially when
it comes to VENDOR tags.  Change this function to no longer be strict in
enforcing the order.

Also, drop checking of rules specific to Probe Responses.  These will
have to be handled separately (most likely by the AP module) since
802.11-2016, Section 11.1.4.3.5 essentially allows just about anything.

050db0b054 netdev: fix association failure path
In netdev_associate_event the ignore_connect_event was getting set true,
but afterwards there were still potential failure paths. Now, once in
assoc_failed we explicitly set ignore_connect_event to false so the
the failure can be handled properly inside netdev_connect_event

two new macros, AKM_IS_PSK/AKM_IS_8021X.
