Once mac80211 starts reporting the used Association Request frame IEs in
the association event, wpa_supplicant will update RSN supplicant IE
information based on that and that will make the AP reject EAPOL-Key msg
2/4 in this particular test scenario due to the hack of including two
RSN IEs in the Association Request frame. Accept this sequence as a
valid test execution in addition to the previously expected connection
to avoid reporting incorrect failures.

Extend wpa_psk_file to allow an optional VLAN ID to be specified with
"vlanid=<VLAN ID>" prefix on the line. If VLAN ID is specified and the
particular wpa_psk_file entry is used for a station, that station is
bound to the specified VLAN. This can be used to operate a single
WPA2-Personal BSS with multiple VLANs based on the used passphrase/PSK.
This is similar to the WPA2-Enterprise case where the RADIUS server can
assign stations to different VLANs.

When I replaced the POS() function with ffs() when applying relevant
parts from the original patch, this ended up breaking the frame
construction since the POS() function was supposed to count the bit
offset for the mask with 0 being the LSB instead of 1 returned by ffs().
Furthermore, ffs() is not available in all C libraries (e.g., not
directly exposed by strings.h on Android), so better not depend on that
or compiler builtins for this since there is no need for this to be as
fast as possible in configuration parsing.
Fix this with a simple function to determine the number of bits the
value needs to be shifted left to align with the mask.

If the ap_handle_timer() timeout is reached for a not-associated STA, do
not default to disassociating that STA first since Disassociation frame
is not really appropriate to send to a STA that is not in associated
state. Instead, skip directly to deauthentication and STA entry removal.

Rather than always iterating elements from frames with pure
u8 pointers, add a type "struct element" that encapsulates
the id/datalen/data format of them.
Then, add the element iteration macros
* for_each_element
* for_each_element_id
* for_each_element_extid
which take, as their first 'argument', such a structure and
iterate through a given u8 array interpreting it as elements.
While at it also add
* for_each_subelement
* for_each_subelement_id
* for_each_subelement_extid
which instead of taking data/length just take an outer element
and use its data/datalen.
Also add for_each_element_completed() to determine if any of
the loops above completed, i.e., it was able to parse all of
the elements successfully and no data remained.

Some of the WNM implementation expects configuration to be available

Add test-eapol program that can be used for fuzzing the EAPOL-Key
Supplicant and Authenticator implementations. This tool can write
Supplicant or Authenticator messages into a file as an initialization
step and for the fuzzing step, that file (with potential modifications)
can be used to replace the internally generated message contents.
The TEST_FUZZ=y build parameter is used to make a special build where a
hardcoded random number generator and hardcoded timestamp are used to
force deterministic behavior for the EAPOL-Key operations. This will
also make the implementation ignore Key MIC and AES keywrap errors to
allow processing of modified messages to continue further.

There is no need to schedule the postponed RSN preauthentication start
if there are no candidates. Avoid wasting eloop resources for this.
This is most useful for fuzz testing of the 4-way handshake
implementation to avoid getting stuck waiting for this unnecessary one
second time when using eloop to coordinate the Authenticator and
Supplicant state machines.

Explicitly check the remaining buffer length before trying to read the

enough buffer room for it would have started by reading one or two
octets beyond the end of the buffer before reporting invalid data at the
following explicit check for buffer room.

p2p->find_start timer was updated on each p2p_find call irrespective of
p2p_find being successful/failed/rejected. For cases where p2p_find was
in progress/pending, another call to p2p_find would be rejected but
p2p->find_start timer would still be updated.
p2p->find_start is maintained in wpa_supplicant to reject the kernel
scan entries before the p2p->find_start time. In above scenario, some of
the scan entries could be discarded even if the Probe Respons frame(s)
were received during the last scan/p2p_find.
This commit changes this to update the p2p->find_start timer only when
call to p2p_find is successful, i.e., a new scan is actually started.

In recent Debian versions, ebtables is an alias managed by
the alternatives(8) mechanism. This means /usr/sbin/ebtables
is a symlink to /etc/alternatives/ebtables, which in turn
links to the real binary.
As we mount a tmpfs over /etc, we cannot access this.
Fix this by bind-mounting the real /etc to /tmp/etc and
adding a symlink from /etc/alternatives to this.
