b907491281 wpa_supplicant: Basic support for PBSS/PCP
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.

Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.

The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

f9982b3212 Implement kqueue(2) support via CONFIG_ELOOP_KQUEUE
NOTE: kqueue has to be closed and re-build after forking. epoll *should*
do the same, but it seems that wpa_supplicant doesn't need it at least.

I have re-worked a little bit of the epoll code (moved into a similar
kqueue function) so it's trivial to requeue epoll if needed in the
future.

df9e2c2a55 D-Bus: Don't do <deny send_interface="..." /> in dbus service file
It does more than intended; apart from denying messages to that
particular interface it also denies all messages non-qualified with an
interface globally. This blocks messages completely unrelated to
wpa_supplicant, such as NetworkManager communication with the VPN
plugins.

From the dbus-daemon manual:

  Be careful with send_interface/receive_interface, because the
  interface field in messages is optional. In particular, do NOT
  specify <deny send_interface="org.foo.Bar"/>! This will cause
  no-interface messages to be blocked for all services, which is almost
  certainly not what you intended. Always use rules of the form: <deny
  send_interface="org.foo.Bar" send_destination="org.foo.Service"/>

We can just safely remove those rules, since we're sufficiently
protected by the send_destination matches and method calls are
disallowed by default anyway.

9684c7567e mesh: Fix peer link counting when a mesh peer reconnects
When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.

This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.

Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

83fe38b011 P2P: Fall back to no VHT when starting AP/P2P GO
In cases where the bandwidth is not set when starting an AP/P2P GO,
the code tries to use 160 MHz or 80 MHz channels. As a result, the
AP/P2P GO configuration is set to use these channel widths even if
they are not available, which may results in failing to start the
AP/P2P GO.

Fix this by changing the AP/P2P GO configuration not to use VHT channels
when they are not available. In this case the AP/P2P GO will use a 40
MHz channel, if available, or a 20 MHz channel, if this is the maximum
available width.

360a9d5a8f P2P: Reduce off channel wait time for some P2P Action frames
Setting a long off channel wait time for P2P Action frames when
we know we are already on the right channel may cause a delay in
sending the Action frame (because the driver may not be able to
satisfy the request for long wait time until previous off channel
requests are over). This may be crucial for P2P response frames
that must be sent within 100 milliseconds of receiving the request.

Fix this by adjusting P2P Action frame wait times as follows:

 1. For GO Negotiation Response frame, shorten the wait time to 100 ms.
    This is reasonable because the peer has just sent us the GO
    Negotiation Request frame, so it is known to be on the right
    channel and is probably ready to send us the GO Negotiation
    Confirmation frame without delay.
 2. For GO Negotiation Confirmation, P2P Invitation Response, and
    Provision Discovery Response frames, there is no need for wait
    time at all as this is the last frame in the exchange. So set
    the wait time to 50 ms to ensure there is enough time to send the
    frame.

d72a00539c RADIUS: Use more likely unique accounting Acct-{,Multi-}Session-Id
Rework the Acct-Session-Id and Acct-Multi-Session-Id implementation to
give better global and temporal uniqueness. Previously, only 32-bits of
the Acct-Session-Id would contain random data, the other 32-bits would
be incremented. Previously, the Acct-Multi-Session-Id would not use
random data. Switch from two u32 variables to a single u64 for the
Acct-Session-Id and Acct-Multi-Session-Id. Do not increment, this serves
no legitimate purpose. Exclusively use os_get_random() to get quality
random numbers, do not use or mix in the time. Inherently take a
dependency on /dev/urandom working properly therefore. Remove the global
Acct-Session-Id and Acct-Multi-Session-Id values that serve no
legitimate purpose.
