After an EAP exchange rsn_info would be uninitialized and in the FT case
we'd use it to generate the step 2 IEs which would cause an RSNE
mismatch during FT handshake.
Until now we'd save the second 32 bytes of the MSK as the PMK and use
that for the PMK-R0 as well as the PMKID calculation. The PMKID
actually uses the first 32 bytes of the PMK while the PMK-R0's XXKey
input maps to the second 32 bytes. Add a pmk_len parameter to
handshake_state_set_pmk to handle that. Update the eapol_eap_results_cb
802.11 quotes to the 2016 version.
handshake_state_install_ptk triggers a call to
netdev_set_pairwise_key_cb which calls netdev_connect_ok, so don't call
netdev_connect_ok after handshake_state_install_ptk. This doesn't fix
any specific problem though.
If the request being cancelled by agent_request_cancel has already been
sent over dbus we need to reset pending_id, the timeout, call l_dbus_cancel
to avoid the agent_receive_reply callback (and crash) and perhaps start
the next request. Alternatively we could only reset the callback and not
free the request, then wait until the agent method to return before starting
the next request.
Move the cancelling of the eapol timeout from the end of step 1 to
step 3 to guard the whole handshake. At the end of step 1 stop the
EAPOL-Start timeout for the case of 802.1X authentication + a cached
PMKSA (not used yet.)
Some APs respond to Neighbor Report Requests with neighbor reports that
have a zero operating class value and a non-zero channel number. This
does not mean that the channel is in the same band that the reporting
AP operates in. Try to guess the band that the channel refers to out of
2.4 and 5GHz -- the bands supported by those APs.
wpa_supplicant also has this workaround in place.
SA Query procedure is used when an unprotected disassociate frame
is received (with frame protection enabled). There are two code
paths that can occur when this disassociate frame is received:
1. Send out SA Query and receive a response from the AP within a
timeout. This means that the disassociate frame was not sent
from the AP and can be ignored.
2. Send out SA Query and receive no response. In this case it is
assumed that the AP went down ungracefully and is now back up.
Since frame protection is enabled, you must re-associate with
the AP.
1. Enforce implementation of handle_request function
2. In case of unimplemented handle_retransmit try to use
handle_request instead and rely on method specific
mechanism to restart the conversation if necessary
3. Make method->free implementation unrequired
When we call scan_periodic_stop and a periodic scan is in progress (i.e.
the trigger callback has been called already) we get no new callback
from scan.c and the device Scanning property remains True forever so set
it to False.
The change from scan_periodic_stop to periodic_scan_stop looks silly but
it's consistent with our naming :)
This patch adds a watcher/parser for the frame event associated with
an AP directed BSS transition (AP roaming). When the AP sends a BSS
transition request, this will parse out the BSS candidate list
(neighbor report) and initiate a roam scan. After this point the
existing roaming code path is reused.
The identity retrieved from simauth was required to include the
prefix for SIM/AKA/AKA', but in reality a real SIM would not
include that prefix in the IMSI. Now the correct prefix is
prepended onto the identity depending on the EAP method.
If the SQN in AUTN is incorrect the simauth module will return
the AUTS parameter, which is sent back to the server and the
servers SQN number is updated.
