process_bss performs two main operations. It adds a seen BSS to a
network object (existing or new) and if the device is in the autoconnect
state, it adds an autoconnect entry as needed. Split this operation
into two separate & independent steps.
To avoid confusion in case of an authenticator side handshake_state
structure and eapol_sm structure, rename own_ie to supplicant_ie and
ap_ie to authenticator_ie. Also rename
handshake_state_set_{own,ap}_{rsn,wpa} and fix when we call
handshake_state_setup_own_ciphers. As a result
handshake_state_set_authenticator, if needed, should be called before
handshake_state_set_{own,ap}_{rsn,wpa}.
After EAPOL logic was moved to eapol.c a check was added to
ap_associate_sta_cb to bitwise compare the AP's RSNE to the RSNE
received in the (Re)Association frame. There is as far as I know no
reason for them to be the same (although they are in our autotest) and
if there was a reason we'd rather validate the (Re)Association RSNE
immediately when received. We also must set different RSNEs as the
"own" (supplicant) and "ap" RSNEs in the handshake_state for validation
of step 2/4 in eapol.c (fixes wpa_supplicant's and MS Windows
connections being rejected)
Make sure we interrupt eapol traffic (4-way handshake) if we receive a
Disassociation from station. Actually do this in ap_del_station because
it's called from both ap_disassoc_cb and ap_success_assoc_resp_cb and
seems to make sense in both cases.
On one hand when we're called with HANDSHAKE_EVENT_FAILED or
HANDSHAKE_EVENT_SETTING_KEYS_FAILED the eapol_sm will be freed in
eapol.c, fix a double-free by setting it to NULL before ap_free_sta
is called.
On the other hand make sure we call eapol_sm_free before setting
sta->sm to NULL in ap_drop_rsna to avoid potential leak and avoid
the eapol_sm continuing to use the handshake_state we freed.
timespec_compare wanted to receive network_info structures as arguments
to compare connected_time timestamps but in one instance we were passing
actual timespec structures. Add a new function to compare plain timespec
values and switch the names for readability.
Make sure stop_ap is called on success and on failure in both tests so
that one can succeed after the other has failed. Also make sure to move
both interfaces out of autoconnect state.
