This helper function had not used the nl80211_set_iface_id() helper, but
there is no reason why it couldn't re-use the same helper as other
places using nl80211_cmd_msg().

This was not really a real issue since bin_clear_free() would not use
the emsk_len argument when emsk is NULL as it would be on the path where
emsk_len has not been initilized. Anyway, it is better to get rid of the
warning.

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.

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.

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.

This flag was left in the STA entry for the short duration after the STA

short time, the AP would not have replied with Deauthentication frame
indicating no association is present.

If invitation to reinvoke a persistent group from the GO fails with the
peer indicating that there are no common channels, there is no defined
means for the peer to indicate which channel could have worked. Since
this type of issue with available channels changing over time can
happen, try to work around this by retrying invitation using one of the
social channels as the operating channel unless a specific operating
channel was forced for the group.
