different reason codes in WoWLAN mode, this commit adds support

Currently, mac80211 does not encrypt or decrypt (Re)Association frames
(Request and Response) because temporal keys are not yet available at
that stage.
With extensions from IEEE P802.11bi, e.g. EPPKE, temporal keys can be
established before association. This enables the encryption and
decryption of (Re)Association Request/Response frames.
Add support to unset the IEEE80211_TX_INTFL_DONT_ENCRYPT flag when
the peer is marked as an Enhanced Privacy Protection (EPP) peer and
encryption keys are available for the connection in non-AP STA mode,
allowing secure transmission of (Re)Association Request frames.
Drop unprotected (Re)Association Request/Response frames received from
an EPP peer.

Add support for the Enhanced Privacy Protection Key Exchange (EPPKE)
authentication protocol in non-AP STA mode, as specified in
"IEEE P802.11bi/D3.0, 12.16.9".
EPPKE is an RSNA authentication protocol that operates using
Pre-Association Security Negotiation (PASN) procedures. It consists
of three Authentication frames with transaction sequence numbers 1, 2,
and 3. The first and third from the non-AP STA and the second from the
AP STA.
Extend mac80211 to process EPPKE Authentication frames during the
authentication phase. Currently, mac80211 processes only frames with
the expected transaction number. In the case of EPPKE, process the
Authentication frame from the AP only if the transaction number matches
the expected value, which is 2.
After receiving the final Authentication frame with transaction number 3
from the non-AP STA, it indicates that both the non-AP STA and the AP
confirm there are no issues with authentication. Since this is the final
confirmation frame to send out, mark the state as authenticated in
mac80211.
For EPPKE authentication, the Multi-Link element (MLE) must be included
in the Authentication frame body by userspace in case of MLO connection.
If the MLE is not present, reject the Authentication frame.

[remove a single stray space]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Currently, in MLO connections, userspace constructs most of the
Authentication frame body, excluding the Multi-Link element (MLE),
which mac80211 appends later in ieee80211_send_auth(). At present,
mac80211 always adds the MLE itself, since userspace
(e.g. wpa_supplicant) does not yet include it.
However, for new authentication protocols such as Enhanced Privacy
Protection Key Exchange (EPPKE), as specified in
"IEEE P802.11bi/D3.0 section 12.16.9", the MLE must be included in
userspace so that the Message Integrity Code (MIC) can be computed
correctly over the complete frame body. Table 9-71 specifies that
the MIC is mandatory. If mac80211 appends the MLE again, the
Authentication frame becomes invalid.
Add a check in ieee80211_send_auth() to detect whether the MLE is
already present in the Authentication frame body before appending.
Skip the append if the MLE exists, otherwise add it as before.

Currently, mac80211 allows key installation only after association
completes. However, Enhanced Privacy Protection Key Exchange (EPPKE)
requires key installation before association to enable encryption and
decryption of (Re)Association Request and Response frames.
Add support to install keys prior to association when the peer is an
Enhanced Privacy Protection (EPP) peer that requires encryption and
decryption of (Re)Association Request and Response frames.
Introduce a new boolean parameter "epp_peer" in the "ieee80211_sta"
profile to indicate that the peer supports the Enhanced Privacy
Protection Key Exchange (EPPKE) protocol. For non-AP STA mode, it
is set when the authentication algorithm is WLAN_AUTH_EPPKE during
station profile initialization. For AP mode, it is set during
NL80211_CMD_NEW_STA and NL80211_CMD_ADD_LINK_STA.
When "epp_peer" parameter is set, mac80211 now accepts keys before
association and enables encryption of the (Re)Association
Request/Response frames.

HT flags don't really make sense when applied to S1G channels
especially given the bandwidths both used for calculations and
conveyed (i.e 20MHz). Similarly with the 80/160/..MHz channels,
each bonded subchannel is validated individually within
cfg80211_s1g_usable(), so the regulatory validation is similarly
redundant. Additionally, usermode application output (such as iwinfo
below) doesn't particularly make sense when enumerating S1G channels:
before:
925.500 MHz (Band: 900 MHz, Channel 47) [NO_HT40+, NO_HT40-, NO_16MHZ]
926.500 MHz (Band: 900 MHz, Channel 49) [NO_HT40+, NO_HT40-, NO_16MHZ]
927.500 MHz (Band: 900 MHz, Channel 51) [NO_HT40+, NO_HT40-, NO_16MHZ, NO_PRIMARY]
after:
925.500 MHz (Band: 900 MHz, Channel 47) [NO_16MHZ]
926.500 MHz (Band: 900 MHz, Channel 49) [NO_16MHZ]
927.500 MHz (Band: 900 MHz, Channel 51) [NO_16MHZ, NO_PRIMARY]
Don't process the S1G band when applying HT flags as both the regulatory
component is redundant and the flags don't make sense for S1G channels.

Right now, the only way to iterate stations is to declare an
iterator function, possibly data structure to use, and pass all
that to the iteration helper function. This is annoying, and
there's really no inherent need for it.
Add a new for_each_station() macro that does the iteration in
a more ergonomic way. To avoid even more exported functions, do
the old ieee80211_iterate_stations_mtx() as an inline using the
new way, which may also let the compiler optimise it a bit more,
