2e8483bf12 Fix authenticator PMKSA cache expiration timer setup
The PMKSA cache expiration timer was not actually ever initialized since
the only place for registering the timeout was in the timeout handler.
Fix this by initializing the timer whenever a new PMKSA cache entry is
added to the beginning of the list (i.e., when it was the first entry or
expires before the entry that was previously going to expire first).

af220315e6 Fix EAPOL frame sending to non-QoS STAs
Commit 4378fc14eb started using QoS Data
frames for QoS STAs. It used the correct flags value for WPA/RSN
EAPOL-Key frames, but wrong flags for IEEE 802.1X EAPOL frames. The
WPA_STA_WMM value used in driver_nl80211.c happens to be identical to
WLAN_STA_ASSOC in sta->flags and this makes driver_nl80211.c try to use
QoS header for all STAs. Fix this by properly converting the flags from
WLAN_STA_* to WPA_STA_*. [Bug 426]

c0810ddb3c P2P: Use the same Dialog Token value for every PD retry
Commit 175171ac6c ensured that the PD
requests are retried in join-a-running group case and the Enrollee is
started on either receiving the PD response or after the retries. Each
PD request is retried with an unique dialog token and a PD response from
the GO with a mismatched dialog token is ignored. Thus, the P2P client
would continue retrying the PD requests till the response with a
matching dialog token is obtained. This would result in the GO getting
multiple PD requests and a corresponding user notification (POP UP) in
implementations where each PD request results in a POP UP, resulting in
a bad user experience. To avoid such behavior, the same dialog token
value is used for every retry in the same PD exchange.

d1ec319f12 Interworking: Continue ANQP fetch after TX failure
If the driver rejected any of the offchannel Action frame TX requests,
the previous implementation terminated ANQP fetch process. While the
driver should not really reject the request normally, it is possible
that a request gets rejected for some reason. Allow the fetch process to
continue with the next AP in such case to avoid breaking networking
selection. This could result, e.g., in auto_interworking=1 process
failing to connect if any the driver rejects requests to any of the APs
in the scan result even if some other APs provided suitable information.

50285f5ca8 P2P: Always re-select operating channel if not hard coded
Since the operating channel is randomly set to 1/6/11 on init, which is
commonly included in the channel intersection, we were effectively
ignoring the set of P2P preferred channels when trying to improve
channel selection after having received peer information. Fix this by
trying to get the best channel we can, unless the user hard coded the
operating channel in the configuration file or p2p_connect command. Fall
back to the initial randomly selected channel if a better one cannot be
chosen.

anywhere else apart from the AP deinit case. As such, it did not really

proper clearing added. As such, it is cleaner to just get rid of this

bb4d4deb4b P2P: Allow PSK to be used instead of passphrase for persistent GO
This continues optimizations for use of CPU heavy pbkdf2_sha1() in GO
setup after the earlier commit 30c371e8a5
by allowing PSK to be used instead of passphrase when creating
persistent group information manually for the GO.

It should be noted that this would not meet the requirements in the P2P
specification (GO shall maintain the passphrase), so this should be used
only when there is no need to allow manual configuration of legacy STAs
using the passphrase.

3dfd0484fc P2P: Consider age for the P2P scan results
cfg80211 caches the scan results according the channel number. Due to
the 15 sec aging this might cause the user mode to see more than one
scan result with the same BSSID, e.g. - one scan result for the
P2P Device and one for the P2P GO (once it's enabled).

Fix this by updating the device entry only if the new peer entry is
newer than the one previously stored.

therefore no countermeasures are started or the countermeasures are

3ab35a6603 Extend EAPOL frames processing workaround for roaming cases
Commit 1ff733383f added a mechanism to
work around issues due to association events and EAPOL RX events being
getting reordered. However, this applied only for the case where
wpa_supplicant is not in associated state. The same issue can happen in
roaming case with drivers that perform BSS selection internally (or in
firmware). Handle that case similarly by delaying received EAPOL frame
processing if the source address of the EAPOL frame does not match the
current BSSID.

Since wired IEEE 802.1X do not have BSSID, make this additional
workaround conditional on BSSID match having been observed during the
previous association.

This fixes issues where the initial EAPOL frame after reassociation was
either dropped (e.g., due to replay counter not increasing) or replied
to with incorrect destination address (the BSSID of the old AP). This
can result in significantly more robust roaming behavior with drivers
that do not use wpa_supplicant for BSS selection.
