f80936094e WMM-AC: Use DEBUG verbosity for ignoring Action frame messages
There is no point in flooding the log with WARNING or ERROR level
messages if WMM-AC related Action frames are ignored in cases where they
were not expected. In addition, WARNING/ERROR should not really be used
in cases an invalid frame is dropped especially if this is not related
to a security setup since external devices could otherwise generate log
entries.

56b352ec58 ERP: Avoid a static analyzer warning on uninitialized emsk_len
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

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).

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.

It was possible for auth/assoc timeout/failure event from the driver to
result in unexpected processing during mesh group setup if that

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.
