4c80937c7f nl80211: Reduce the number of nlctrl name resolution calls
The number of nlctrl name resolution calls required to connect to a
WPA2-PSK AP is 12. And each nlctrl name resolution call spends 55 micro
seconds on a lower spec CPU like Intel Atom N270. Reduce the number of
nctrl name resolution calls from 12 to 1 by caching the results of nctrl
name resolution calls on int size memory to speed up the connection
process a little bit.

Generate an event on the control socket interface when a network is
added or removed. The event name CTRL-EVENT-NETWORK-<ADDED|REMOVED>
is followed by the network entry identifier. The event matches the
corresponding Network<Added|Removed> signal on the d-bus interface.

e2e9adc3d9 openssl: Disable padding after initializing the cipher suite
according to OpenSSL documentation [1], EVP_CIPHER_CTX_set_padding()
should be called after EVP_EncryptInit_ex(), EVP_DecryptInit_ex(), or
EVP_CipherInit_ex(). Not doing this causes EVP_CIPHER_CTX_set_padding()
to return false on OpenSSL-3.0.0, resulting in the impossibility to
connect in many scenarios. Fix this changing the order of function calls
where needed.

d265dd2d96 openssl: Remove deprecated functions from des_encrypt()
NetworkManager-CI detected systematic failures on test scenarios using
MSCHAPv2 when wpa_supplicant uses OpenSSL-3.0.0.
The 'test_module_tests.py' script also fails, and the following log is
shown:

 1627404013.761569: generate_nt_response failed
 1627404013.761582: ms_funcs: 1 error

It seems that either DES_set_key() or DES_ecb_encrypt() changed their
semantic, but it doesn't make sense to fix them since their use has been
deprecated. Converting des_encrypt() to avoid use of deprecated
functions proved to fix the problem, and removed a couple of build
warnings at the same time.

445dbe2cdb P2P: Do not stop Listen state if it is moving to correct channel
Commit 0b8889d8e5 ("P2P: Do not stop Listen state if it is on
correct channel") added a optimization to use Listen state's
remain-on-channel to send out GO Negotiation response frame quickly.

But in Listen state, if GO Negotiation request frame is received before
the remain-on-channel started event from the driver, the above
optimization is not triggered. This showed up in following manner in the
debug log:

p2p0: Starting radio work 'p2p-listen'@0xb4000070ae22d420 after 0.000114 second wait
nl80211: Remain-on-channel cookie 0x100 for freq=2412 MHz duration=204
P2P: Received GO Negotiation Request from 6e:fa:a7:86:e5:e5(freq=2412)
P2P: GO Negotiation with 6e:fa:a7:86:e5:e5
P2P: Stopping find
P2P: Clear timeout (state=WAIT_PEER_CONNECT)
P2P: State WAIT_PEER_CONNECT -> IDLE
nl80211: Cancel remain-on-channel with cookie 0x100
p2p0: Radio work 'p2p-listen'@0xb4000070ae22d420 done in 0.074348 seconds
p2p0: radio_work_free('p2p-listen'@0xb4000070ae22d420): num_active_works --> 0
P2P: State IDLE -> GO_NEG
P2P: Sending GO Negotiation Response
Off-channel: Send action frame: freq=2412 dst=6e:fa:a7:86:e5:e5 src=da:3c:83:7d:70:2b bssid=da:3c:83:7d:70:2b len=196
nl80211: Remain-on-channel event (cancel=0 freq=2412 channel_type=0 duration=400 cookie=0x100 (match))
nl80211: Remain-on-channel event (cancel=1 freq=2412 channel_type=0 duration=0 cookie=0x100 (match))
P2P: GO Negotiation Response (failure) TX callback: success=0

Fix this by adding p2p->pending_listen_freq == freq condition for the
optimization so that the case where the remain-on-channel command has
already been issued to the driver, but the start event has not yet been
received, is covered as well.

49442194c4 SAE: Derive H2E PT while reconnecting to same SSID also
P2P connections in the 6 GHz band use SAE authentication algorithm after
getting credentials with WPS connection. During WPS connection as it
doesn't use SAE, SAE PT is not derived. After getting SAE credentials,
the STA connects to the same SSID using SAE auth algorithm. Earlier, SAE
H2E PT was not derived while connecting to the same SSID to which the
STA is connected last time. Due to this, the P2P group formation fails
for 6 GHz channels when H2E is enabled as the PT will not be setup by
the P2P client before proceeding to the SAE authentication. Same could
happen with infrastructure WPS when wps_cred_add_sae=1 is used.

Set up the SAE H2E PT while connecting to the same SSID again also to
make sure that the H2E PT is set up in the STA to derive the PWE for
successful SAE authentication. The PT derivation will be skipped in
wpa_s_setup_sae_pt() if PT is already available for that SSID.

1071f75395 DPP2: Fix channel 6 inclusion for chirping with non-2 GHz interfaces
When the driver provides a list of supported modes, hostapd ended up
adding channel 6 even if the 2.4 GHz mode was not included. This
resulted in incorrect behavior of trying to transmit on a not supported
channel in case of 5 GHz only radios.

Fix this by adding the channel 6 by default only if the driver does not
provide a list of supported modes. Whenever the supported modes are
available, only add this channel if it is explicitly listed as an
enabled channel.

This is similar to an earlier wpa_supplicant change in commit
8e5739c3ac ("DPP2: Check channel 6 validity before adding it to chirp
channel list").

b4f7506ff0 FILS: Flush external-PMKSA when connection fails without ERP keys
External applications can store PMKSA entries persistently and
reconfigure them to wpa_supplicant after restart. This can result in
wpa_supplicant having a PMKSA for FILS authentication without having
matching ERP keys for it which would prevent the previously added
mechanism for dropping FILS PMKSA entries to recover from rejected
association attempts.

Fix this by clearing PMKSA entries configured by external applications
upon FILS connection failure even when ERP keys are not available.

80bcd7ecd1 FILS: Flush PMKSA entries on FILS connection failure
wpa_supplicant generates both a PMKSA cache entry and ERP keys upon
successful FILS connection and uses FILS authentication algorithm for
subsequent connections when either ERP keys or a PMKSA cache entry is
available.

In some cases, like AP/RADIUS server restart, both ERP keys and PMKSA
becomes invalid. But currently when an AP rejects an association,
wpa_supplicant marks only ERP keys as failed but not clearing PMKSA.

Since PMKSA is not cleared, consecutive connection attempts are still
happening with FILS authentication algorithm and connection attempts are
failing with the same association rejection again instead of trying to
recover from the state mismatch by deriving a new ERP key hierarchy.

Clear PMKSA entries as well on association rejection from an AP to allow
the following connection attempt to go with open authentication to
re-establish a valid ERP key hierarchy. Also, since clearing PMKSA
entries on unprotected (Re)Association Response frames could allow DoS
attack (reduce usability of PMKSA caching), clear PMKSA entries only
when ERP keys exists.

9557ba336b AP: Don't increment auth_transaction upon SAE authentication failure
IEEE Std 802.11-2016, 12.4.7.6 specifies:

An SAE Commit message with a status code not equal to SUCCESS shall
indicate that a peer rejects a previously sent SAE Commit message.

An SAE Confirm message, with a status code not equal to SUCCESS, shall
indicate that a peer rejects a previously sent SAE Confirm message.

Thus when SAE authentication failure happens, authentication transaction
sequence number should not be incremented.

the end. However, the hostapd interface for this netdev was only added,
but not removed at the end of the test case. This could result in

if running WPS configuration steps that get applied to all enabled

84f8947735 PTKSA: Fix a potential hostapd memory leak during reconfiguration
Some of the reconfiguration cases (e.g., with WPS reconfiguration
enabling WPA/WPA2) might end up calling hostapd_setup_wpa() twice
without calling hostapd_deinit_wpa() in the middle. This would have
resulted in a memory leak since the PTKSA cache was being reinitialized
without freeing previous memory allocation.

Fix this by making PTKSA cachine initialization independent of
hapd->wpa_auth so that reinitialization does not happen in a manner that
would have overridden the old hapd->ptksa pointer without freeing the
referenced resources.
