02a8d45ace ERP: Add support for ERP on EAP peer
Derive rRK and rIK on EAP peer if ERP is enabled. The new wpa_supplicant
network configuration parameter erp=1 can now be used to configure the
EAP peer to derive EMSK, rRK, and rIK at the successful completion of an
EAP authentication method. This functionality is not included in the
default build and can be enabled with CONFIG_ERP=y.

If EAP authenticator indicates support for re-authentication protocol,
initiate this with EAP-Initiate/Re-auth and complete protocol when
receiving EAP-Finish/Re-auth.

d3bddd8b84 ERP: Add support for ERP on EAP server and authenticator
Derive rRK and rIK on EAP server if ERP is enabled and use these keys to
allow EAP re-authentication to be used and to derive rMSK.

The new hostapd configuration parameter eap_server_erp=1 can now be used
to configure the integrated EAP server to derive EMSK, rRK, and rIK at
the successful completion of an EAP authentication method. This
functionality is not included in the default build and can be enabled
with CONFIG_ERP=y.

0d4e3d1d13 nl80211: Ignore Connect failure for the previous association
Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).

This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

44177b69e8 Allow a BSS entry with all-zeros BSSID to expire
wpa_bss_in_use() used to determine that a BSS with BSSID of
00:00:00:00:00:00 is in use in almost every case since either
wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This
could result in a corner case of a BSS entry remaining in the BSS table
indefinitely if one was added there with a (likely bogus) address of
00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and
wpa_s->pending_bssid if the BSSID in the BSS table entry is
00:00:00:00:00:00.

In theory, that address is a valid BSSID, but it is unlikely to be used
in any production AP, so the potential expiration of a BSS entry with
that address during a connection attempt would not be a concern
(especially when a new scan would be enough to recover from that).

c7f35a9e96 tests: Make scan_for_auth more robust
It was apparently possible for this test case not to do what it was
supposed to do, i.e., get nl80211 Authenticate command failing due to
cfg80211 BS entry missing. With the external radio work blocking fixed,
this can be cleaned up by explicitly waiting for the scan event. In
addition, a less used channel can be selected to avoid finding other BSS
entries.

4f9a5ea5cc WPS: Fix current_ssid clearing on duplicate network removal
It was possible for the current network profile to be deleted when
merging duplicated WPS credentials. However, this did not clear
wpa_s->current_ssid and it was possible for something else to end up
dereferencing that pointer to now freed memory. This could be hit, e.g.,
with ap_wps_mixed_cred. Fix this by clearing current_ssid also in this
code path similarly to other cases of network block getting removed.

e4a35f07d9 mesh: Skip fast-association when using connect_without_scan
The mesh group addition was designed to use wpa_s->connect_without_scan
to skip a scan. That path was skipped if wpa_supplicant_fast_associate()
allowed previous scan results to be used. This could result in undesired
double-initialization attempt for the mesh interface. Avoid this by not
using wpa_supplicant_fast_associate() when wpa_s->connect_without_scan
is set.

9a700ff9ef Ignore auth/assoc timeout events in mesh configuration
It was possible for auth/assoc timeout/failure event from the driver to
result in unexpected processing during mesh group setup if that
operation was started before the previously started driver operation to
association/connect had completed. Since those events cannot happen in
mesh cases, ignore them to avoid issues due to this corner case.

For example, monitor_iface_unknown_sta followed by wpas_mesh_secure test
case resulted in failure without this change.

0a11409c00 Fix omac1_aes_128_vector() not to read beyond addr/len array
Previously, it was possible for the loop through the data components to
increment addr/len index at the last position beyond the declared size.
This resulted in reading beyond those arrays. The read values were not
used and as such, this was unlikely to cause noticeable issues, but
anyway, memory checkers can detect this and the correct behavior is to
stop increments before going beyond the arrays since no more bytes will
be processed after this anyway.
