802.11 defines GAS (generic advertisement service) which can be used
to query supported advertisement protocols from an AP before
authentication/association. Hotspot/OSEN only care about the ANQP
protocol, but the way the IE is structured potentially requires
iterating through several tuples before you reach the ANQP protocol
identifier. Because of this we define all protocol identifiers.
Inside print_ie_vendor, the Microsoft OUI is checked for a WPA IE. The
variable name for the OUI was wfa_oui, but this OUI is not actually the
WiFi-Alliance (sometimes refered to as 'wfa') but rather the Microsoft
OUI.
There is a common interface lookup in many tests in order to initialize
the HostapdCLI object e.g.:
for intf in hostapd_map.values():
if intf.config == 'ssidOWE.conf':
hapd = HostapdCLI(intf)
break
Instead of having to do this in every test, HostapdCLI will now
optionally take a config file (config=<file>). The interface object
will still be prefered (i.e. supplying an interface will not even
check the config file) as to not break existing tests. But if only
a config file is supplied the lookup is done internally.
There are some tests that do still need the interface, as they do
an interface lookup to initialize both hostapd and hwsim at the
same time.
This adds some checks for the FT_OVER_FILS AKMs in station and netdev
allowing the FILS-FT AKMs to be selected during a connection.
Inside netdev_connect_event we actually have to skip parsing the IEs
because FILS itself takes care of this (needs to handle them specially)
FILS unfortunately is a special case when it comes to fast transition.
We have to process the FT IEs internally since we cannot trigger the
same initial mobility association code path (via netdev).
FT over FILS-SHA384 uses a 24 byte FT MIC rather than the 16 byte MIC
used for all other AKMs. This change allows both the FT builder/parser
to handle both lengths of MIC. The mic length is now passed directly
into ie_parse_fast_bss_transition and ie_build_fast_bss_transition
FILS-FT is a special case with respect to the PTK keys. The KCK getter
was updated to handle both FT-FILS AKMs, by returning the offset in
the PTK to the special KCK generated during FILS. A getter for the KCK
length was added, which handles the SHA384 variant. The PTK size was
also updated since FILS-FT can generate an additional 56 bytes of PTK
The start_ap method was raising potential dbus errors before converting
them to an IWD error type. This is due to dbus.Set() not taking an error
handler. The only way to address this is to catch the error, convert it
and raise the converted error.
Two new hardware configuration keys were added:
[radX]
iftype_disable=station,ap,adhoc,p2p_client,p2p_go,mesh_point
cipher_disable=wep40,wep104,tkip,ccmp,bip
Any of the above values are supported and can be disabled.
Support is coming to configure radios with a specific set of interface
type and cipher support, so the input to create_hwsim_radio is better
suited to use a parameter structure rather than adding more parameters.
The radio_confs key was parsed in a way that required all radios
to be specified in the list. This isnt optimal, as you may want to
specially configure a certain radio, while keeping all the others
default.
This change reworks some logic and allows any radio to be specially
configured on its own.
mac80211_hwsim now allows setting supported iftypes/ciphers. This patch
enables this support in hwsim. Specific iftypes/ciphers can now be
disabled via the command line when creating a radio:
Disable iftypes:
--iftype-disable station,ap,adhoc,p2p_client,p2p_go,mesh_point
Disable cipher types:
--cipher-disable ccmp,tkip,wep
The test should be aborted if there are not enough radios that support
AP mode. The iftype attribute will now be parsed during the wiphy dump
and a flag is set on the wiphy so we know to skip this radio when
creating the hostapd instances. Since hostapd gets started first, it
will automatically choose all the radios it needs which support AP mode.
This leaves the remainder of the radios (potentially STA only) for IWD.
