8f3e9c91a8 hostapd: backport BSSID black/whitelists
This change adds the configuration options "bssid_whitelist" and
"bssid_blacklist" used to limit the AP selection of a network to a
specified (finite) set or discard certain APs.

This can be useful for environments where multiple networks operate
using the same SSID and roaming between those is not desired. It is also
useful to ignore a faulty or otherwise unwanted AP.

In many applications it is useful not just to enumerate a group of well
known access points, but to use a address/mask notation to match an
entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00).

This is especially useful if an OpenWrt device with two radios is used to
retransmit the same network (one in AP mode for other clients, one as STA for
the uplink); the following configuration prevents the device from associating
with itself, given that the own AP to be avoided is using the bssid
'C0:FF:EE:D0:0D:42':

config wifi-iface
	option device 'radio2'
	option network 'uplink'
	option mode 'sta'
	option ssid 'MyNetwork'
	option encryption 'none'
	list bssid_blacklist 'C0:FF:EE:D0:0D:42/00:FF:FF:FF:FF:FF'

4ea1edf840 hostapd: Add uapsd option to netifd.sh
The uapsd option sets the uapsd_advertisement_enabled flag in hostapd.

The check for phy support is already implemented here in hostapd since 2011:
http://w1.fi/cgit/hostap/commit/?id=70619a5d8a3d32faa43d66bcb1b670cacf0c243e

So this can be safely set to 1 as default.

d5b734e145 hostapd: Add wpa_psk_file option to netifd.sh
The wpa_psk_file option offers the possibility to use a different WPA-PSK key for each client. The directive points to a file with the following syntax:

mac_address wpa_passphrase_or_hex_key

Example:

00:11:22:33:44:55 passphrase_for_client_1
00:11:22:33:44:67 passphrase_for_client_2
00:11:22:33:44:89 0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef

So it is possible to specify both ASCII passphrases and raw 64-chars hex keys.

0d7e8ba3a9 hostapd: fix "bad number" error due to missing wps_pbc_in_m1 option (since r39995)
r39995 introduced a new parameter wps_pbc_in_m1 to wifi wps config, but
apparently did not provide a default value 0.

When that option's non-existing value is later evaluated in
/lib/netifd/hostapd.sh, it causes the "bad number" error to be logged in
syslog if user has not set the wps_pbc_in_m1 option. The error materialises
only if user has enabled wps.

My patch sets the parameter's default value to 0, which does nothing. The
default might also be set a bit later in the function, but this felt like the
most clear place to do that.

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

541fbfbb9e hostapd: correctly handle macfile uci option
Make hostapd.sh correctly handle the macfile uci option.

Such option specifies the macfile name to pass into the
hostapd configuration file. Moreover, if a maclist option
has been specified, copy the macfile before appending new
entries.
