wpa_group_update_count and wpa_pairwise_update_count can now be used to
set the GTK and PTK rekey retry limits (dot11RSNAConfigGroupUpdateCount
and dot11RSNAConfigPairwiseUpdateCount). Defaults set to current
hardcoded value (4).
Some stations may suffer from frequent deauthentications due to GTK
rekey failures: EAPOL 1/2 frame is not answered during the total timeout
period of currently ~3.5 seconds. For example, a Galaxy S6 with Android
6.0.1 appears to go into power save mode for up to 5 seconds. Increasing
wpa_group_update_count to 6 fixed this issue.

Issue:
------
The test setup has 2 peers running MACsec in PSK mode, Peer A with
MAC address higher than MAC Address of peer B. Test sequence is
1. Peer B starts with actor_priority 255
2. Peer A starts with priority 16, becomes key server.
3. Peer A stops..
4. Peer A restarts with priority 255, but because of the stale values
participant->is_key_server(=TRUE) and participant->is_elected(=TRUE)
it continues to remain as Key Server.
5. For peer B, key server election happens and since it has lower MAC
address as compared to MAC address of A, it becomes the key server.
Now we have 2 key servers in CA and is not correct.
Root-cause & fix:
-----------------
When number of live peers become 0, the flags such lrx, ltx, orx,
otx, etc. need to be cleared. In MACsec PSK mode, these stale values
create problems while re-establishing CA.

API ieee802_1x_mka_decode_dist_sak_body() wrongly puts
participant->to_use_sak to TRUE, if Distributed SAK Parameter Set of
length 0 is received. In MACsec PSK mode, this stale incorrect value can
create problems while re-establishing CA. In MACsec PSK mode, CA goes
down if interface goes down and ideally we should be able to
re-establish the CA once interface comes up.

Relying on the group_capab from the P2P peer information can result in
improper information on whether the peer is currently operating as a GO.
However, there is a known implementation in Android that does this.
To reduce issues from this misuse in upper layer to try to determine
whether a specific peer is operationg a group, override the group_capab
value in P2P_PEER output with 0 if there are no BSS entries with the
peer P2P Device as a GO. This is not a perfect information since there
may not have been a recent scan on all channels, but this results in
less issues than trying to decide between new group formation and
joining an existing group based on stale or incorrect information.
Since no upper layer application is really supposed to use the
group_capab field value in P2P_PEER command, this change should not
cause any impact for properly design components and the possibility of
regressions is limited to cases that are already known to work
incorrectly in number of identifiable cases.

P802.11i/D3.0 described the Key Length as having value 16 for the group
key handshake. However, this was changed to 0 in the published IEEE Std

Std 802.11-2016). We need to maintain the non-zero value for WPA (v1)

While the IEEE Std 802.11-2016 is still indicating that GNonce would be
exchanged in EAPOL-Key messages (see, e.g., Figure 12-52 showing the
Send EAPOL-Key operation in the REKEYNEGOTIATING state or the sample
group key handshake in Figure 12-47), there are also examples of
describing this field as having value zero (e.g., 12.7.7.2 Group key
handshake message 1).
GNonce is used only with the Authenticator and the Supplicant does not
have any use for it, so it is better not to expose that internal value.
Hardcode the Key Nonce field to 0 in EAPOL-Key group message 1/2.

The local custom version of allocating and initializing struct
hostapd_data within wpa_supplicant_mesh_init() is problematic. This has
already missed couple of initialization steps that are required. Instead
of trying to remember to keep this up to date, use
hostapd_alloc_bss_data() so that there is only one place for this
initialization.
This is fixing a recent issue where FILS HLP started using
hapd->dhcp_server and expected that to be initialized to -1. For the
mesh case, that did not happen and when removing the interface, the FILS
HLP implementation ended up unregistering eloop socket for
hapd->dhcp_server (= 0). This could result in missing socket callbacks
for an arbitrary socket.

This wpa_drv_if_remove() call was previously modified to fix a different
issue, but that fix resulted in unconditional use of treed memory here
(wpa_supplicant_deinit_iface() frees wpa_s). Make a local copy of
wpa_s->parent to be able to use it after wpa_s is freed. The
mesh_if_created case has wpa_s->parent != wpa_s, so this should be
sufficient way of handling the wpa_drv_if_remove() call here.

The hostapd processing of the AES-SIV AAD was incorrect. The design for
the AAD changed between P802.11ai/D7.0 and D8.0 from a single vector
with concatenated data to separate vectors. The change in the
implementation had missed the change in the aes_siv_decrypt() call for
the num_elem parameter. This happened to work with the mac80211
implementation due to a similar error there.
Fix this by using the correct numbers of vectors in the SIV AAD so that
all the vectors get checked. The last vector was also 14 octets too long
due to incorrect starting pointer, so fix that as well. The changes here
are not backwards compatible, i.e., a similar fix in the Linux mac80211
is needed to make things interoperate again.

While RFC 5295 uses "8" as the value to use in the length field in KDF
context when deriving EMSKname, it is clearer to use the macro defining
EMSKname as the value since the KDF design in RFC 5295 encodes the
length of the derived data in octets in that part of the context data.
This change is just making the implementation easier to understand while
not actually changing the behavior.

Unlike the EMSKname and rRK derivations, rIK derivation is actually
using the "optional data" component in the context data (see RFC 5295).
RFC 6696 defines that optional data to be the cryptosuite field for rIK.
This was missing from the previous implementation and that resulted in
incorrect rIK being derived.
In addition, the rIK Label string does not actually include the "EAP "
prefix in the way as the rRK Label in RFC 6696 does. This would also
have resulted in incorrect rIK value.
Fix rIK derivation by adding the cryptosuite value into the KDF context
data and fixing the label string. This change is not backwards
compatible and breaks all ERP use cases (including FILS shared key
authentication) with older (broken) and new (fixed)
hostapd/wpa_supplicant builds.
