955c88a64a ie: Consistently set group_management_cipher
RSNE_ADVANCE may return and if it is before the assignment of
info.group_management_cipher, that assignment will be dependent on where
the RSNE ends.

316752c5e4 ie: Error in tlv_iter_next if no space to length byte
When parsing the EAPoL-Key key data field we don't strip the 0xdd /
0x00 padding from the decrypted data so there may be trailing padding
after the IE sequence and valgrind will report an invalid read of the
length byte.  Same thing may happen if we're sent garbage.

9a47f98ccd eap-wsc: Store M2 for future use
We need quite a bit of attributes of M2 for the duration of the WSC
handshake.  Most importantly, we need to use the peer's public key when
processing M4 and M6.  RegistrarNonce is also needed for generating any
ACK/NACK messages as needed.

Also, peer's device attributes such as Model, Manufacturer, etc might be
useful to report upon successful handshake.

2cbbcb7434 eap-wsc: Load settings related to DevicePassword
DevicePassword is the PIN, either static, dynamically generated or
entered by the user.  For PushButton mode, DevicePassword is set to
'00000000'.  It can also be provided via external means, such as NFC.

This patch allows DevicePassword to be externally configured into the
EAP-WSC layer.  Optionally, the secret nonce values can also be
provided for testing purposes.  If omitted, they will be generated using
l_getrandom.

 - Manufacturer
 - Model Name
 - Model Number
 - Serial Number
 - Device Name
 - Primary Device Type
 - OS Version

Session specific parameters
 - MAC Address
 - Configuration Methods
 - RF Bands

The following parameters are auto-generated for each new session, but
can be over-ridden if desired

2c88c37f99 netdev: Cancel the CMD_CONNECT genl command on disconnect
CMD_DISCONNECT fails on some occasions when CMD_CONNECT is still
running.  When this happens the DBus disconnect command receives an
error reply but iwd's device state is left as disconnected even though
there's a connection at the kernel level which times out a few seconds
later.  If the CMD_CONNECT is cancelled I couldn't reproduce this so far.

b601c99123 device: Modify disconnect_cb logic
Calling device_disassociated inside disconnect_cb was mostly pointless.
Most attributes were already cleared by device_disconnect() when
initiating the disconnection procedure.

This patch also modifies the logic for triggering the autoconnect.  If
the user initiated the disconnect call, then autoconnect should not be
triggered.  If the disconnect was triggered by other means, then iwd
will still enter autoconnect mode.

f4201d06c2 device: Remove pointless check
This was introduced by commit f468fceb02.
However, after commit 2d78f51fac66b9beff03a56f12e5fb8456625f07, the
connect_cb is called from inside netdev_disconnect.  This in turn causes
the dbus-reply to be sent out if needed.  So by the time we get to the
code in question, connect_pending is always NULL.

c4eab62ba4 netdev: Improve netdev_connect error/cancel logic
Try to make the connect and disconnect operations look more like a
transaction where the callback is always called eventually, also with a
clear indication if the operation is in profress.  The connected state
lasts from the start of the connection attempt until the disconnect.

1. Non-null netdev->connected or disconnect_cb indicate that the operation
   is active.
2. Every entry-point in netdev.c checks if connected is still set
   before executing the next step of the connection setup.  CMD_CONNECT and
   the subsequent commands may succeed even if CMD_DISCONNECT is called
   in the middle so they can't only rely on the error value for that.
3. netdev->connect_cb and other elements of the connection state are
   reset by netdev_connect_free which groups the clean-up operations to
   make sure we don't miss anything.  Since the callback pointers are
   reset device.c doesn't need to check that it receives a spurious
   event in those callbacks for example after calling netdev_disconnect.

a phy rename, so we can't use it to subsequently read

/sys/class/rfkill/rfkill%u/../index and

005213a3d4 netdev: Implement new_wiphy hint
When a new wiphy is added, the kernel usually adds a default STA
interface as well.  This interface is currently not signaled over
nl80211 in any way.

This implements a selective dump of the wiphy interfaces in order to
obtain the newly added netdev.  Selective dump is currently not
supported by the kernel, so all netdevs will be returned.  A patch on
linux-wireless is pending that implements the selective dump
functionality.

During the network_info refactoring the adding of the connected BSS to
device->bss_list in case it is not in the scan results has moved to
after the l_hashmap_foreach_remove call meaning that the network could
be removed even though it is still pointed at by
device->connected networks.  Reverse the order to what it was before.

Alternatively network_process network could take not of the fact the
network is connected and not call network_remove on it leaving it with
an empty bss_list.

It is probably rare that a disconnect should fail but if it happens the
device->state is not returned to CONNECTED and I'm not sure if it should
be, so the ConnectedNetwork property and other bits should probably be
reset at the start of the disconnection instead of at the end.

Also check if state is CONNECTED before calling network_disconnected
because network_connected may have not been called yet.

network.c to avoid having two separate lists of network_info structures
and keeping them in sync.  That turns out to be difficult because the

can be triggered in both network.c or knownnetworks.c.  Both can also

9daf1f3fcf network: Refactor network_info usage
For simplicity and future use (possibly performance), every struct network
gets a pointer to a network_info structure, there's one network_info for
every network being by any interface, not only known networks.  The SSID
and security type information is removed from struct network because the
network_info holds that information.

network_info also gets a seen_count field to count how many references
from network.info fields it has, so as to fix the removal of
network_info structures.  Previously, once they were added to the
networks list, they'd stay there forever possibly skewing the network
ranking results.

This also fixed the network ranking used by GetOrderedNetwork which
wasn't working due to a missing assignment of *index in
network_find_info also triggering valgrind alerts.

a0468fb9be device: Implement GetOrderedNetworks()
Keep an updated sorted list of networks in addition to the "networks"
hashmap.  The list can be queried through the GetOrderedNetworks dbus
method.

We also take advantage of that list to get rid of a single
l_hashmap_foreach in new_scan_results.

ca3cd12fb0 network: General network rank calculation
A function that calculates a new rank type to order all networks
currently seen by a netdev.  The order is designed for displaying the
list to user so that the networks most likely to be wanted by the user
are first on the list.

dae897854b network: return boolean from network_rankmod
Since the rankmod value only makes sense for autoconnectable networks,
change network_rankmod to return an indication of whether the rankmod is
valid as a boolean instead of as a double, as discussed before.

e07b24e5d8 wiphy: Move NULL check to device_disassociated
Do nothing in device_disassociated if device->connected_network
indicates we are not associated.  This may happen if the device was
connected since before iwd was started, this should possibly be fixed
separately by querying device state when device is detected.

2285ad24ab network: Create a settings file on connection
Make sure networks of all 4 security types have a settings file created
or updated with a new modification time on a successful connect so that
autoconnect and network sorting works for networks other than PSK too.

By doing this on storage_network_touch failure we make sure we don't
overwrite anything dropped into the settings directory while we were
connecting.

33d2ae60e9 network: Use security_to_str instead of switch(security)
Convert switch (network->security) statements to security_to_str to be
consistent across network.c in how the settings file name ending is
obtained.

1ba2630216 networks: Simplify parameters
for network_seen and network_connected

Only accept a struct network pointer instead of separately the ssid and
security type.  This is needed so we can do some more simplification in
the next patch by having access to the network struct.
