07b17c6b25 hostapd: allow multiple key management algorithms
To enable 802.11r, wpa_key_mgmt should contain FT-EAP or FT-PSK. Allow
multiple key management algorithms to make this possible.

4482d10a04 hostapd: append nasid to config for all WPA types
The 802.11r implementation in hostapd uses nas_identifier as PMK-R0 Key
Holder identifier. As 802.11r can also be used with WPA Personal, nasid
should be appended to the hostapd config for all WPA types.

3bc4516ebb hostapd: Add optional support for hostapd own_ip_addr in wireless config
`own_ip_addr` is used by hostapd as NAS-IP-Address.
This is used to identify the AP that is requesting the authentication of the
user and could be used to define which AP's can authenticate users.
Some vendors implement only NAS-Identifier or NAS-IP-Address and not both.
This patch adds ownip as an optional parameter in /etc/config/wireless.

ff40bc2db9 hostapd: recognize 8021x as an authentication mode
Currently, in order to configure the authentication daemon in
8021x mode, we need to set wireless.@wifi-iface[0].encryption="wpa"
Though it works it confuses folks as 8021x is using WEP
encryption and not WPA. Therefore the terminology itself is
confusing. This change adds 8021x as a recognized string for 8021x
authentication.

9beaea6fc2 hostapd: add external registrar support
Setting wireless.@wifi-iface[N].ext_registrar=1 will enable UPNP
advertising and add an external registrar to the interface this vif
belongs to (br-lan if the vif is included in the LAN bridge). By
enabling this we append upnp_iface=xxx to the hostapd config file.

bcbc9b1e89 hostapd: fix hostapd RSN preauthentication PMKSA caching
In 2009 OpenWrt's hostapd config added an "auth_cache" boolean
to be used to address a reported issue #12129 [0] on a forum [1].
The reported issue on the ticket is different that the one
described on the forum. The commit was r33359. This change broke
proper RSN preauthentication [2] [3] [4] expectations on hostapd's
configuration for WPA2 and this in turn disabled PMKSA caching and
Opportunistic Key Caching. This change:

  * Leaves the "auth_cache" to be used only for WPA networks for those
    looking to use this as a workaround to a reported issue but annotates
    a warning over its usage.

  * Separate "auth_cache" from WPA2 RSN preauthentication, leaving
    WPA2 RSN preauthentication to enabled only with "rsn_preauth" with
    the expected and recommended settings.

  * Adds a new WPA2 RSN preauthentication "rsn_preauth_testing" to
    be used when evaluating funcionality for WPA2 RSN preauthentication
    with the expected and recommended settings with the only difference
    so far with what should be enabled by default to disable Opportunistic
    Key Caching.

Disabling the PMKSA cache should mean the STA could not roam off and back
onto the AP that had PMKSA caching disabled and would require a full
authentication cycle. This fixes this for WPA2 networks with
RSN preauthentication enabled.

This change should be applied to AA as well as trunk.

  TL DR;

The issue described on the forum has to do with failure of a STA
being able to try to authenticate again with the AP if it failed
its first try. This may have been an issue with hostapd in 2009
but as per some tests I cannot reproduce this today on a WPA2
network.

The issue described on the ticket alludes to a security issue with the
design of using a Radius server to authenticate to an AP. The issue
vaguely alludes to the circumstances of zapping a user, deleting their
authentication credentials to log in to the network, and that if
RSN preauthentication is enabled with PMKSA caching that the user
that was zapped would still be able to authenticate.

Lets treat these as separate issues.

I cannot reproduce the first issue reported on the forums of not
being able to authenticate anymore on a WPA2 network.

The issue reported on the ticket modified WPA2 RSN preauthentication
by adding two fields to the hostapd configuration if auth_cache
was enabled:

  * disable_pmksa_caching=1
  * okc=0

The first one disables PMKSA authentication cache.
The second one disables Opportunistic Key Caching.

The issue reported on the ticket was fixed by implementing a workaround
in hostapd's configuration. Disabling PMKSA caching breaks proper use
of WPA2 RSN pre authentication. The usage of disable_pmksa_caching=1
prevents hostapd from adding PMKSA entries into its cache when a successful
802.1x authentication occurs. In practice RSN preauthentication would
trigger a STA to perform authentication with other APs on the same SSID,
it would then have its own supplicant PMKSA cache held. If a STA roams
between one AP to another no new authenitcation would need to be performed
as the new AP would already have authenticated the STA. The purpose of the
PMKSA cache on the AP side would be for the AP to use the same PMKID for
a STA when the STA roams off onto another BSSID and later comes back to it.

Disabling Opportunistic Key Caching could help the reported issue
as well but its not the correct place to address this. Opportunistic
Key Caching enables an AP with different interfaces to share the
PMKSA cache. Its a technical enhancement and disabling it would
be useful to let a testing suite properly test for RSN preauthentication
given that otherwise Opportunistic Key Caching would enable an
interface being tested to derive its own derive the PMKSA entry.
In production though okc=1 should be enabled to help with RSN
preauthentication.

The real fix for this particular issue outside of the scope of hostapd's
configuration and it should not be dealt with as a workaround to
its configuration and breaking expected RSN preauthentication and
technical optimizations. Revert this change and enable users to pick
and choose to enable or disable disable_pmksa_caching and okc expecting them
to instead have read clearly more what these do.

As for the core issure ported, the correct place to fix this is to
enable a sort of messaging between the RADIUS server and its peers
so that if caching for authentication is enabled that cache can be
cleared upon user credential updates. Updating a user password
(not just zapping a user) is another possible issue that would need
to be resolved here. Another part of the solution might be to reduce
the cache timing to account for any systematic limitations (RADIUS
server not able to ask peers to clear cache might be
one).

9a22315ca4 hostapd: Settings for DAE/CoA server
hostapd supports "Dynamic Authorization Extensions", making it possible
to forcibly disconnect a user by sending it a RADIUS "Disconnect-Request"
packet.

I've added three new variables to enable setting of the
"radius_das_client" and "radius_das_port" variables in the hostapd
configuration, which enable these extensions.

* dae_client - IP of the client that can send disconnect requests
* dae_secret - shared secret for DAE packets

These are combined into the "radius_das_client" option in hostapd.conf
To enable the server, both dae_client and dae_secret must be set.

* dae_port - optional, default value is 3799 as specified in RFC 5176

Previously only the first macfilter configuration would have been used

already. Hence, move the macfilter setup into hostapd.sh where and
create one mac list file per vif.
