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).

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.

There is no need to maintain a separate counter for this in addition to
the pointer to the current location. In addition, this gets rid of
warnings about unused variable write.

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.

The scan result comparison routine would not make much sense without
current BSS level known, so return from the function without going
through the iteration that could have dereferenced the pointer if
wpa_s->current_bss == NULL.

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.

If wpa_driver_roboswitch_read() fails before such comparison, the values
that are being compared are not initialized properly and as such, there
is not much point in comparing them either.

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.

record->type == NULL case was handled through the record->type_length
comparison. While this was correct, it is a bit difficult for static
analyzers to understand, so add an extra check for NULL to avoid false

This is the older design that some drivers may still use if they do not
support offloaded offchannel TX operations.

no_offchannel_tx=1 driver parameter can now be used to force the older
remain-on-channel -based offchannel TX design to be used with
mac80211_hwsim. This can be used to increase test coverage with the
hwsim test cases.

It was possible for the error path to try to use P2P Group ID attribute
even if one was not included in the message. This could result in

The special case of non-zero status code used in a GAS Comeback Response
frame to indicate that additional delay is needed before the response is
available was not working properly. This case needs to allow the status

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.

PD Response is sent out using a 200 ms offchannel wait, but that wait
was not cancelled on TX status report. This could result in offchannel
operation being left waiting unnecessarily long. Fix this by making the
P2P_NO_PENDING_ACTION case in Action TX callback cancel the wait if a
pending wait is marked (and mark this for PD Response).

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.

This verifies that 'INTERWORKING_SELECT auto' is able to pick the
correct network based on priority configuration when connected to a
lower priority network.

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
last-network selection behave more consistently with Interworking
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.
