When FILS authentication is used with ERP, no EAPOL frames are expected
after association. However, for drivers that set the
WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X capability flag, the EAP state
machine was not configured correctly and was waiting for EAPOL frames,
which leads to disconnection.
Fix this by reordering the if branches to set the EAPOL/EAP state
machines to success when FILS authentication was already completed.

When processing the NL80211_CMD_PROBE_CLIENT command response, the
nl80211 layer in the kernel sends a response containing the cookie
associated with the client probe request. This response was not handled
by driver_nl80211.c when sending the command, and it was mistakenly
handled as an asynchronous event. This incorrect event did not include
the MAC/ACK attributes, so it was ignored in practice, but nevertheless,
the command response should not be processed as an event.
Fix this by reading the response as part of the sending the command
flow.

Include the MAC address of the peer, knowledge of whether the poll was
ACKed, and cookie into the debug message to make this more useful.

SA Query wasn't stopped after disconnection, which could potentially
result in an unexpected SA timeout firing later when already connected
to another AP. Fix that by stopping SA Query when an association is
terminated.

pending_p2ps_group flag is not always cleaned, which may later result
in an unexpected GO bring up, after PD response is transmitted in
wpas_prov_disc_resp_cb().
This can be seen when running the following hwsim tests together:
- p2ps_channel_sta_connected_disallow_freq_mcc
- p2ps_channel_active_go_and_station_different_mcc
Fix this by clearing pending_p2ps_group flag also when processing new
PD requests. In addition, set this flag only when really needed.

It looks like it is possible for the RECEIVE state to leak memory where
a previously allocated sm->lki is moved to sm->oki while sm->oki is
pointing to not yet freed entry. It is not clear how this can be
triggered, but it has come up in hwsim testing under heavy load.
Free sm->oki if it is still set in RECEIVE before replacing it with
sm->lki to avoid this memory leak.

If os_get_random() fails, llid must not be read/used since it could be

The TSF field in BSS termination information was not cleared correctly.
It was supposed to be cleared to all zeros, but the memset call did not
point at offset 2; instead, it cleared it with 0x02 octets and also
cleared the subelement header with 0x02 octets while leaving two last
octets uninitialized.

wpas_p2p_completed() used wpa_sm_get_p2p_ip_addr() return value properly
for filling in the ip_addr[] string only if the IP addresses got
assigned, but the raw ip[] array was passed to
wpas_dbus_signal_p2p_group_started() regardless of whether the IP
addresses were assigned. This could result in using uninitialized stack
memory for constructing the GroupStarted signal values. Fix this by
filling those in only if the IP addressed are actually available.

exception as a warning from WpaSupplicant.__del__ for the dev1 instance

Move event.assoc_info.freq selection to be after the
nl80211_get_assoc_ssid() call so that the current cfg80211 information
on the operating channel can be used should anything unexpected have
happened between the association request and completion of association.
Furthermore, update bss->freq based on assoc_freq to make that
information a bit more useful for station mode. It was already updated
after channel switches during association, but not at the beginning of
association.

This fixes some issues where bss->freq could have been used to replace
the current operating channel when sending out a management frame.
bss->freq has not been consistently used to track the current operating
channel in station mode, so it should not be trusted for this type of
uses. Clearing it makes this a bit more robust by at least avoiding the
cases of information from past association being used.

None of the ECC groups supported in the implementation had a cofactor
greater than 1, so these checks are unreachable and for all cases, the
cofactor is known to be 1. Furthermore, RFC 5931 explicitly disallow use
of ECC groups with cofactor larger than 1, so this checks cannot be
needed for any curve that is compliant with the RFC.
Remove the unneeded group cofactor checks to simplify the
implementation.
