The construction used here to figure out the offset of variable length
IEs in Probe Request frames was a bit odd looking and resulted in a
warning from a static analyzer, so replace it with more standard use of
offsetof().

The flags argument is used to indicate a failure case (0x80) which
allows erp == NULL. This may be a bit too difficult combination for
static analyzers to understand, so add an explicit check for !erp as
another condition for returning from the function before the erp pointer
gets dereferenced without checking it.

drv cannot be NULL here (it is dereferenced even on the preceding line)
and anyway, os_free(NULL) is allowed, so remove the redundant check.
Signed-off-by: Jouni Malinen <j@w1.fi>
The eap argument to this function is never NULL and the earlier
ieee802_1x_learn_identity() call is dereferencing it anyway, so there is
no point in checking whether it is NULL later in the function.

This verifies a case where the neighboring BSS is at the other end of
the band and has its PRI channel further away.
Signed-off-by: Jouni Malinen <j@w1.fi>
This needs to find the PRI channel also in cases where the affected
channel is the SEC channel of a 40 MHz BSS, so need to include the
scanning coverage here to be 40 MHz from the center frequency. Without
this, it was possible to miss a neighboring 40 MHz BSS that was at the
other end of the 2.4 GHz band and had its PRI channel further away from
the local BSS.

There is no need to have a separate "fail silently" case for wpa_ie_len
== 0. That condition does not seem to be reachable and even if it were,
the following "ie len too short" case will result in the exact same
return value.

As far as IEEE 802.11 standard is concerned, WEP is deprecated, but at
least in theory, allowed as a group cipher. This option is unlikely to
be deployed anywhere and to clean up the implementation, we might as
well remove all support for this combination.

Call the FT processing function directly instead of going through
wpa_supplicant_event() to process FT Authentication frame in SME case.
This allows parsing error to be used to trigger immediate failure for
the connection instead of trying to proceed to reassociation step that
cannot succeed.

In case of a network interface removal, check if the interface
was also the parent interface of the P2P Device dedicated interface.
If this is the case, then stop the P2P Device functionality, and
remove the P2P Device dedicated interface.
In case that the interface is added again and P2P Device
functionality can be enabled again, add a new P2P Device dedicated
interface and allow further P2P Device functionality.
In case that the P2P Device dedicated interface is re-created, the
original P2P Device configuration file is needed, so store it in
the global params (instead in the wpa_interface configuration).

Android libnl_2 implementation added support for "nl80211" name in
commit 'libnl_2: Extend genl_ctrl_resolve() to support "nl80211" name'
in July 2012 which got included in Android 4.2. It is fine to drop this
old Android ICS workaround from wpa_supplicant now.

wpas_p2p_get_ht40_mode() used blacklist approach (bw != BW20) to find
the relevant op_class, but didn't take into account other non-BW40
cases, like BW80, that had been added to the bw enum after the initial
implementation. Fix this by looking for the specific BW40 bw cases.

This is equivalent to the P2P_REMOVE_CLIENT command on control
interface. This can be used to remove the specified client [as object

persistent) from the local GO.

PBC overlap detection searches for another BSS with active PBC in the
BSS table. However, when a separate P2P interface is used, scan results
without P2P IE are not saved in the BSS table, so non-P2P BSS's with
active PBC will not be detected.
Fix this by iterating only the WPS AP array instead of the BSS table.
This is also more efficient since only WPS APs may have active PBC. This
also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device
is used.

Use the global control interface to list the P2P Device persistent
networks. Get and parse the P2P-GROUP-STARTED events, so later the
interface names would be available for the connectivity test etc. Both
of these are required when a dedicated P2P Device interface is used.
