78789d95b4 Remove unnecessary variable initialization
The following if statements set the new_op_mode value in all cases,
so there is no need to initialize this to 0 first. This removes a
static analyzer warning.

e997bc75dd Remove a static analyzer warning about unused variable write
The pos variable was not used between its first and second assignment.
Clean this up by using the pos variables instead of the buf (start of
the buffer).

ea3b8c1d2d Do not use a separate variable for tracking first entry in a list
The pos pointer can be compared to the start of the buffer pointer to
determine whether the entry is the first one in the list. This gets rid
of some static analyzer warnings about unused variable writes.

7b6e81575f Clean up hostapd add_iface error path operations
If hapd_iface->bss[i] == NULL, this could have resulted in NULL pointer
dereference in the debug print. Avoid this by skipping the message in
case of NULL pointer. In addition, clear iface->bss[i] to NULL for
additional robustness even though this array gets freed immediately.

67adcd266c WNM: Check wpa_s->current_bss more consistently
The scan result comparison routine would not make much sense without

wpa_s->current_bss == NULL.

3ff8073db7 EAP-FAST: Use clear eap_get_config() result validation
This was previously checked through the eap_peer_tls_ssl_init() call
which made it difficult for static analyzers. Add an explicit check for
config == NULL into the beginnign of eap_fast_init() since this will
always result in initialization failing anyway.

3d91a0470f DFS: Make sure center frequency is always initialized for VHT
This seemed to be fine on most code paths, but the code was complex
enough to make the analysis difficult (and a bit too much for static
analyzers). There is no harm in forcing these parameters to be
initialized, so do that to make sure they cannot be left uninitialized.

06c7b7f0b5 HS 2.0R2: Fix temporary network disabling in Deauth Req case
Commits 7ef6947993 and
533536d82a added this temporarily
disabling case, but those commits were merged in without having been
converted to the new os_reltime design used for ssid->disabled_until.
Consequently, they ended up disabling the network for 44 years or so too
long time (depending on what values the relative timestamp had
accummulated so far). Fix this by using relative timestamps
consistently.

1578796a31 TDLS: Work around interop issues with supported operating class
It looks like some deployed devices may send an invalid supported
operating class element (length = 0) in TDLS Setup messages. With
cfg80211, this results in the NL80211_CMD_SET_STATION command failing
due to an invalid argument (cfg80211 mandates supported operating
classes information to have a length of 2..253 octets).

Work around this interop issue by ignoring the Supported Operating Class
element if it has invalid length.

b7fb98f072 Interworking: Fix already-connected check to verify network priority
Commit d28f4e44f1 optimized Interworking
network selection in a case where the operation is run while already
connected to the selected network by skipping the reconnection. However,
this did not take into account that a higher priority network may have
shown up in the new scan results.

Fix this by checking whether network selection based on the latest scan
results (the ones from the interworking_select operation) would result
in a network with higher priority being selected. If so, skip the
optimization and force normal network connection (which will select this
newly found higher priority network). This fixes cases where a
non-Hotspot 2.0 network with higher priority (e.g., home network) shows
up while connected to a Hotspot 2.0 network with lower priority.

Commit 3d910ef497 tried to make

network selection preferences. However, it did not take into account
that other network block may have higher priority. In such cases, the
last added network from Interworking network selection should actually
not be selected for the next connection. Fix this by limiting the
last-network preference to work only within a priority class.
