Commit b6c3931ad6 introduced an AP-side
workaround for key reinstallation attacks. This option can be used to
mitigate KRACK on the station side, in case those stations cannot be
updated. Since many devices are out there will not receive an update
anytime soon (if at all), it makes sense to include this workaround.
Unfortunately this can cause interoperability issues and reduced
robustness of key negotiation, so disable the workaround by default, and
add an option to allow the user to enable it if he deems necessary.

One of the latest mac80211 updates added sanity checks, requiring the
beacon intervals of all VIFs of the same radio to match. This often broke
AP+11s setups, as these modes use different default intervals, at least in
some configurations (observed on ath9k).
Instead of relying on driver or hostapd defaults, change the scripts to
always explicitly set the beacon interval, defaulting to 100. This also
applies the beacon interval to 11s interfaces, which had been forgotten
before. VIF-specific beacon_int setting is removed from hostapd.sh.
Fixes FS#619.

Setting legacy_rates to 0 disables 802.11b data rates.
Setting legacy_rates to 1 enables 802.11b data rates. (Default)
The basic_rate option and supported_rates option are filtered based on this.
The rationale for the change, stronger now than in 2014, can be found in:

The balance of equities between compatibility with b clients and the
detriment to the 2.4 GHz ecosystem as a whole strongly favors disabling b
rates by default.

`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.

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.

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).

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
