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.

Interworking: Do not share ANQP info if none was received

Verify that the other BSS has actually received some valid ANQP
information before sharing the results from it. This fixes potential
issues with cases where some of the APs with the same HESSID has invalid
ANQP configuration.

Interworking: Do not schedule new scan if process is terminating

The GAS query compilation callback may happen after the wpa_supplicant
process has been requested to terminate. Avoid scheduling a new eloop
timeout for a scan in such a case.

nl80211: Restore previous nlmode if set_freq for AP mode fails

wpa_driver_nl80211_ap() returned error if set_freq failed, but left the
previously set nlmode to GO/AP. While this should not be issue for most
purposes, it leaves the interface in somewhat unexpected state and could
potentially affect operations prior to next connection attempt. Address
this by restoring the previous nlmode if AP mode cannot be started for
some reason.

P2P: Use the same Dialog Token value for every PD retry

Commit 175171ac6c3f2bb501897237d559de0fedfd992e 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.

EAP-AKA server: Fix fallback to full auth

Commit 68a41bbb44ac78087076ce65e6c1803d036bc4a2 broke fallback from
reauth id to fullauth id by not allowing a second AKA/Identity round to
be used after having received unrecognized reauth_id in the first round.
Fix this by allowing fullauth id to be requested in such a case.

wpa_supplicant: Save frequency configuration parameter

In case of wpa_supplicant IBSS and AP modes after we will call wpa_cli

after wpa_supplicant restart we have frequency = 0 and AP start will
fail.

eapol_test: Allow full RADIUS attribute length to be used

The -N and -C command line parameters can be used to add arbitrary

about 128 bytes when the actually message was constructed. Fix this by
using larger buffers to allow the maximum attribute length (253 octets
of payload) to be used. [Bug 458]

Fix EAPOL frame sending to non-QoS STAs

Commit 4378fc14ebfb355705e7674bf347ea659bcd77bc 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]

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).
