The new optional ssid=<hexdump> argument to P2P_CONNECT can be used to
make P2P Client operations during join-an-existing-group more robust by
filtering out scan results based on the SSID in addition to the P2P
Device/Interface Address. This can help if the same MAC address has been
used in multiple groups recently and the cached scan results may still
include an older BSS.

At least one of the wpas_p2p_connect() callers (NFC join case) already
had access to the Group SSID. Pass that information through
wpas_p2p_connect() to wpas_p2p_join() so that the join operation can
filter out incorrect groups more easily.

Accept only a BSS entry matching the SSID when trying to find the
operating channel of a GO during join operation for which the SSID was
already specified. Previously, it could have been possible to pick an
incorrect BSS entry if the new GO was not found in the latest scan and
there was an older cached scan entry for the same BSSID.

Use wpa_bss_get() with the specific Group SSID instead of
wpa_bss_get_bssid_latest() if the SSID is already known. This makes the
P2P join operations more robust in case the frequency of the group was
not yet known and the same P2P Interface Address may have been used in
multiple group instances with an older group entry still present in the
cached scan results.

When we receive FST Setup Request when session already exists, the
following validations take place:
1. we drop the frame if needed according to MAC comparison
2. we drop the frame if the session is "not pending", i.e., if FST
Setup Response was already exchanged (sent or received).
There are two issues with the above:
1. MAC comparison is relevant only before the Setup Response exchange.
In other words, Setup Request should not be dropped due to MAC
comparison after Setup Response has been exchanged.
2. Receiving Setup Request after Setup Response exchange most likely
means that FST state machine is out of sync with the peer. Dropping
the Setup Request will not help solve this situation.
The fix is:
1. do MAC comparison only if session is "pending", i.e., Setup Response
was not yet exchanged.
2. In case Setup Response was already exchanged, reset our session and
handle the Setup Request as if it arrived when session doesn't exist.

While this could in theory be claimed to be ready for something to be

This makes some static analyzers complain about stored value never being
read. While it is good to clear some other temporary variables, this
local variable i has no security private information (it has a fixed
value of 20 here) and trying to clear it to 0 does not add any value.

As a dedicated P2P Device interface does not have a network
interface associated with it, trying to call linux_iface_up()
on it would always fail so this call can be skipped for
such an interface.
Getting interface nlmode can be done only after bss->wdev_id is
set, so move this call to wpa_driver_nl80211_finish_drv_init(),
and do it only in case the nlmode != NL80211_IFTYPE_P2P_DEVICE.

IEEE Std 802.11-2012 11.3.5.4 specifies the PMKID for SAE-derived keys
as:

This is already calculated in the SAE code when the PMK is derived, but
not saved anywhere. Later, when generating the PMKID for plink action
frames, the definition for PMKID from 11.6.1.3 is incorrectly used.
Correct this by saving the PMKID when the key is generated and use it
subsequently.

Commit 986de33d5c ('Convert remaining SSID
routines from char* to u8*') started using wpa_ssid_txt() to print out
the SSID for the Called-Station-Id attribute in RADIUS messages. This
was further modified by commit 6bc1f95613
('Use printf escaping in SSID-to-printable-string conversion') to use
printf escaping (though, even without this, wpa_ssid_txt() would have
masked characters).
This is not desired for Called-Station-Id attribute. While it is defined
as a "String", RFC 2865 indicates that "a robust implementation SHOULD
support the field as undistinguished octets.".
Copy the SSID as an array of arbitrary octets into Called-Station-Id to
avoid any kind of masking or escaping behavior. This goes a step further
from the initial implementation by allowing even the possible (but
unlikely in practical use cases) 0x00 octet in the middle of an SSID.
