The SAE unit test was written when group 19 was preferred by default for
all SAE connections. However, we have now started to prefer higher
security groups. Trick the test into using group 19 by wrapping
l_ecc_supported_ike_groups implementation to return just curve 19 as a
supported curve.
The timeout functionality was removed from the core SAE
implementation as it causes issues with kernel behavior.
Because of this the timeout tests are no longer valid,
nor is a few asserts in the end-to-end test.
The SAE unit test needed to be updated to use the handshake_driver,
but in addition all the packet building needed a major overhaul. SAE
was changed to behave more like OWE/FILS, in that netdev passes the
raw mpdu frame into the RX callbacks. Before, only the authentication
data was passed. This requires the unit tests to now build up the
entire authentication frame, and in some cases append the header
to the data coming from the TX functions.
When this test was written only group 19 was supported. The 'bad_group'
test used, at the time, unsupported group 20. Now group 20 is supported
so this test was expecting a failure. This updates the test to use group
0xff, which is not a valid ECC group and should always fail.
Now that the peer element is validated we must send valid point data.
This should have been done in the beginning anyways, but since the
point data was not previously validated this test still passed.
Since this particular unit test is really testing timeouts we can just
use the commit buffer for other tests since it contains a valid scalar
and point.
