Commit 83935317a7 added forced
disconnection in case of 4-way handshake failures. However, it should
not have changed the case where the supplicant is requesting fallback
to full EAP authentication if the PMKID in EAPOL-Key message 1/4 is
not know. This case needs to send an EAPOL-Start frame instead of
EAPOL-Key message 2/4.
This works around a problem with APs that try to force PMKSA caching
even when the client does not include PMKID in (re)association request
frame to request it. [Bug 355]
Commit c02d52b405 removed direct calls
to the WPA authenticator, but the change here was incorrect.
EAPOL_SM_USES_WPA was supposed to be set based on sta->wpa_sm being
set, i.e., no need to check for PMKSA entries for that.
While this could potentially change EAPOL Key TX state machine behavior,
no clear problems have been identified so far. Anyway, better fix this
to get the correct flags set for EAPOL authenticator state machine.
When using WPS, we may end up here if the STA manages to re-associate
without the previous STA entry getting removed. Consequently, we need to
make sure that the WPA state machines gets initialized properly at this
point.
62477841a1 tried to address fragmentation
issues, but it did not address the case where the final EAP-TNC
message gets fragmented. Move the state update to the correct place
to address this case, too.
There are no subdirectories in any of these directories or plans
for adding ones. As such, there is no point in running the loop
that does not do anything and can cause problems with some shells.
Both the wildcard VLAN entry and the statically configured VLAN
interfaces should behave in the same way. Initializing the
full dynamic VLAN code before adding the statically configured VLAN
interfaces allows the same processing to be applied to both statically
and dynamically added VLAN interface (i.e., also the statically
configured ones will be added to a bridge).
This allows wpa_supplicant to be started quickly with an empty
configuration. If an external program wants to fetch scan results
from wpa_supplicant, it will need to request a scan explicitly
in this type of case.
The WPS IE was overriding the WPA/RSN IE in driver based MLME case
(hostapd_notif_assoc), but the MLME code here was not using WPS IE
correctly, i.e., it allowed the WPA/RSN IE override the operation.
The returned buffer length was hardcoded to be the prime length
which resulted in shorter results being padded in the end. However,
the results from DH code are supposed to be unpadded (and when used
with WPS, the padding is done in WPS code and it is added to the
beginning of the buffer). This fixes WPS key derivation errors
in about 1/256 of runs ("WPS: Incorrect Authenticator") when using
the internal crypto code.
Add "wpa-ft-psk", "wpa-psk-sha256", "wpa-ft-eap" and "wpa-eap-sha256"
possible KeyMgmt values of interface capabilities to fit values in
BSS RSN options dictionary.
This adds more details into the CTRL-EVENT-DISCONNECTED event to
make it easier to figure out which network was disconnected in some
race conditions and to what could have been the reason for
disconnection. The reason code is currently only available with
the nl80211 driver wrapper.
