clang complains about enum as var_arg type
because of the argument standard conversion.
In a small test I did neither clang nor gcc can
properly warn about out of range values, so it's
purely for documentation either way.
There are situations when a CMD_DISCONNECT or deauthenticate will be
issued locally because of an error detected locally where netdev would
not be able to emit a event to the device object. The CMD_DISCONNECT
handler can only send an event if the disconnect is triggered by the AP
because we don't have an enum value defined for other diconnects. We
have these values defined for the connect callback but those errors may
happen when the connect callback is already NULL because a connection
has been estabilshed. So add an event type for local errors.
These situations may occur in a transition negotiation or in an eapol
handshake failure during rekeying resulting in a call to
netdev_handshake_failed.
Some unit tests expect to be running from the top level iwd tree
directory to load certificates and such. Make sure that test-runner
chdirs to the appropriate directory prior to running the unit tests.
The kernel parses NL80211_ATTR_USE_MFP to mean an enumeration
nl80211_mfp. So instead of using a boolean, we should be using the
value NL80211_MFP_REQUIRED.
Otherwise the EAP-MD5 driver is not found and we get the following
output:
TEST: EAPoL/8021x EAP-TTLS+EAP-MD5 & 4-Way Handshake
Error initializing EAP for ifindex 1
Program received signal SIGSEGV, Segmentation fault.
Make the use of EAPOL-Start the default and send it when configured for
8021x and either we receive no EAPOL-EAP from from the AP before
timeout, or if the AP tries to start a 4-Way Handshake.
On certain routers, the 4-Way handshake message 3 of 4 contains a key iv
field which is not zero as it is supposed to. This causes us to fail
the handshake.
Since the iv field is not utilized in this particular case, it is safe
to simply warn rather than fail the handshake outright.
