ie_tlv_builder_init takes a size_t as input, yet for some reason
ie_tlv_builder_finalize takes an unsigned int argument as output. Fix
the latter to use size_t as well.
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Because of this the timeout tests are no longer valid,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.
WSC EAP method always results in failure, even if successful. Failed
eapol_sm sessions are auto-cleaned, so there's no need to do this
explicitly. Also eapol_exit() will clean up any left-over sessions, so
drop this to make the code a bit simpler.
Incorporate the LGPL v2.1 licensed implementation of ARC4, taken from
the Nettle project (https://git.lysator.liu.se/nettle/nettle.git,
commit 3e7a480a1e351884), and tweak it a bit so we don't have to
operate on a skip buffer to fast forward the stream cipher, but can
simply invoke it with NULL dst or src arguments to achieve the same.
This removes the dependency [via libell] on the OS's implementation of
ecb(arc4), which may be going away, and which is not usually accelerated
in the first place.
There's are two changes to the example raw data in m8_encrypted_settings,
one is to change the Network Index value to 1 and the other is to drop
the Network Key Index attribute:
Network Index R Deprecated - use fixed value 1 for
backwards compatibility.
Network Key O Deprecated. Only included by WSC 1.0
Index devices. Ignored by WSC 2.0 or newer
devices.
test-eapol was passing zero as the MTU, so this simply needed to be
updated to remove that parameter.
test-wsc was actually setting a MTU value so when building the
settings we now add the proper value so the MTU can be set with
__eap_set_config.
Refactored eapol_sm_test_tls to take a l_settings object rather than
a settings string. This lets the caller either load from data or
from file (the new test loads the build time generated tls-settings
file).
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.
