There is no need to trigger new SA Query procedure to check the state of
the connection immediately after having performed such a check. Limit
the impact of burst of unprotected Deauth/Disassoc frames by starting a
new SA Query procedure only once at least 10 seconds has passed from the
previous SA Query that was triggered by reception of an unprotected
disconnection. The first SA Query procedure for each association does
not follow this rule to avoid issues with test cases that expect to see
an SA Query every time.

Use a local variable and size_t in length comparison to make this easier
for static analyzers to understand. In addition, set the return list and

These do not change the actual behavior of the only caller for this
function, but clarifies what the helper function is doing.

This was added by commit 8a45811638
('hostapd: Add Operating Mode Notification support'), but the validation
steps cannot be true either for the channel width (which is a two-bit
subfield that cannot encode more than the list four values) or Rx NSS
(which cannot encode a value larger 7). Furthermore, the VHT_CHANWIDTH_*
defines do not match the definition of the Channel Width subfield
values.
Since this check cannot ever match, it is better to remove it to make
the code easier to understand and to avoid getting complaints about dead
code from static analyzers.

Commit b36935be1a ('nl80211: Fix EAPOL
frames not being delivered') and commit
147848ec4d ('nl80211: Do not add all
virtual interfaces to drv->if_indices') were not fully in sync and it
was possible for some non-hostapd use cases to end up adding undesired
ifindexes into the list of interfaces from which events and EAPOL frames
are processed on the parent interface. This could result, e.g., in P2P
Device management interface on getting unexpected events, including
RTM_NEWLINK event that could end up getting interpreted as an
indication of the interface being down and unavailable.
Make both add_ifidx() calls use the same criteria for adding interfaces
to the local list. This is not really a complete solution, but it is
good enough for now to fix the most visible side effects of this issue.

Performing a P2P Device flow such as p2p_listen or
p2p_find, can degrade the performance of an active interface
connection, if the listen frequency is different than the
frequency used by that interface.
To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change
will be possible only in case that the listen channel is not forced
externally, and will be delayed to a point where the P2P Device
state machine is idle.
The optimization can be configured in the configuration file and
is disabled by default.
