While the FILS authentication cases were already using the proper PMK
length (48 octets instead of the old hardcoded 32 octet), the initial
association case had not yet been updated to cover the new FILS SHA384
AKM and ended up using only a 32-octet PMK. Fix that to use 48-octet PMK
when using FILS SHA384 AKM.

The output length was incorrect (32 from the copy-pasted SHA256
version). Fix this to return the correct number of octets (48) for
SHA384. This fixes incorrect key derivation in FILS when using the
SHA384-based AKM.

HTTP response was previously sent as a plaintext without the HTTP header
on port 12345. By default Android webview/Chrome assumes plaintext as
HTTP/0.9 data. Android webview/Chrome has removed support of HTTP/0.9
request/response on non-standard ports, i.e., other than port 80. This
results in error while opening URL 'http://localhost:12345/'.
Fix this by prefixing the HTTP response with the HTTP/1.1 header.

Previously the peer operating channel preference was accepted if the
indicated frequency was listed in the local preference list from the
driver. This was assuming that the driver included only channels that
are currently enabled for GO operation. Since that might not be the
case, filter the local preference list by doing an explicit validation
of the indicated channels for P2P support.
This moves the similar validation steps from two other code paths in
p2p_check_pref_chan_recv() and p2p_check_pref_chan_no_recv() into a
common filtering step in p2p_check_pref_chan() for all three cases.
This avoids issues to start the GO in cases where the preferred
frequency list from the driver may include channels that are not
currently enabled for P2P GO use (e.g., 5 GHz band in world roaming
configuration).

Previously, the est_throughput comparison was done only when SNR
difference was less than 5 dB. Since the throughput estimation take into
account SNR, this can be done in more cases. For now, add a conservative
2 dB more to the difference so that any SNR difference below 7 dB
results in BSS selection based on throughput estimates.
In addition, the throughput estimates require SNR values to be
available, so separate this from the 5 GHz preference that can be done
based on either SNR or qual values.

This allows throughput estimates and 5 GHz preference over 2.4 GHz band
to be used in more cases. The previously used value of 30 was
significantly more conservative than the SNR limits used for the highest
rate in scan_est_throughput() and this resulted in cases where 5 GHz AP
was ignored while SNR with it would have been close to reaching the
maximum TX rate.

The url argument to ieee802_11_send_bss_trans_mgmt_request() was
hardcoded to NULL in the only caller, so this code cannot be reached.
wnm_send_bss_tm_req() construct the same frame with more generic
parameters, including option for including the URL, so
ieee802_11_send_bss_trans_mgmt_request() can be simplified.

The length of the WNM-Sleep element was not verified before using it.
This could result in reading the subfields in this element (total of
four octets) beyond the end of the buffer. Fix this by ignoring the
element if it is not long enough to contain all the subfields.

The struct wpa_stsl_negotiation seemed to have been for some kind of
tracking of state of PeerKey negotiations within hostapd. However,
nothing is actually adding any entries to wpa_auth->stsl_negotiations or
using this state. Since PeerKey does not look like something that would
be deployed in practice, there is no justification to spend time on
making this any more complete. Remove the dead code now instead of
trying to figure out what it might be used for.

Add support to set sched scan relative RSSI parameters so that the
drivers can report BSSs after relative comparision with the current
connected BSS. This feature is applicable only when in connected mode.
The below commands can be used to configure relative RSSI parameters
SET relative_rssi <disable|rssi_value>
disable - to disable the feature
rssi_value - amount of relative RSSI in dB
SET relative_band_adjust <band:adjust_value>
band - "2G" or "5G" for 2.4 GHz or 5 GHz respectively
adjust_value - amount of RSSI to be adjusted in dB

Issue: When 2 peers are running MACsec in PSK mode with CA
established, if the interface goes down and comes up after
time > 10 seconds, CA does not get re-established.
Root cause: This is because retry_count of both the peers
would have reached MAX_RETRY_CNT and stays idle for other to
respond. This is clear deadlock situation where peer A waits
for MKA packets from peer B to wake up and vice-versa.
Fix: If MACsec is running in PSK mode, we should send MKPDUs
forever for every 2 seconds.
