b3a395091d scan: Switch all uses of ifindex to wdev_id
The ifindex is used to index the netdevs in the system (wlan, ethernet,
etc.) but we can also do wifi scanning on interfaces that have no
corresponding netdev object, like the P2P-device virtual interfaces.
Use the wdev id's to reference interfaces, the nl80211 api doesn't care
whether we use a NL80211_ATTR_IFINDEX or NL80211_ATTR_WDEV.  Only
wireless interfaces have a wdev id.

ec60b51d01 scan: Fix sc->get_scan_cmd_id logic
Save the actual cmd_id returned from l_genl_family_dump and zero it in
the get_scan_done.  There's no need to zero it in scan_cancel because
get_scan_done gets called automatically.

5223dee050 scan: Reference scan_context directly from scan_results
Store the scan_context pointer in scan_results directly instead of
storing the ifindex.  We now cancel ongoing GET_SCAN commands when the
scan_context is being freed so there's no point going through the extra
step of looking up the scan_context by ifindex inside the command
callback to guard against non-existent scan_contexts.

5ca3c4495e resolve: fix crash in resolve_exit
method.ops is NULL, which causes method.ops->exit to crash. This
adds a check that method.ops is not NULL before dereferencing.

e5dedc3378 auto-t: add HESSID hotspot autotest

e8d91f15a1 hotspot: allow HESSID without NAIRealmNames
The original idea was to allow the provisioning file to include HESSID
without the NAIRealmNames. Configuring this way would allow for ANQP
to be skipped completely, assuming the AP advertises its HESSID.

The way the code was written still required NAIRealmNames to be
provided in the provisioning file.

cdc80cd341 auto-t: add copy_to_hotspot
Initially the solution to copying files to .hotspot was to use the
existing copy_to_storage, but allow full directory copying. Doing it
this way does not allow us to copy single files into .hotspot which
makes it difficult to test single configurations in several consecutive
tests.

This adds a new API, copy_to_hotspot, where a single hotspot config
can be provided. clear_storage was also modified to clear out the
.hotspot directory in addition to the regular storage directory.

bd4446070f manager: Create interfaces with a random mac
If supported by the driver, we can create an interface directly with a
random MAC if configured to do so.  If the driver does not have this
capability, then tell netdev to perform the necessary logic as part of
the interface initialization procedure.

1e9f9e61f1 wiphy: Remove unused regulatory query / notifications
Regulatory domain management is now completely handled by the kernel, so
iwd doesn't really need to query or be aware of changes to this.  This
may change in the future, but for now this code has not been used and
can be safely gotten rid of.

23a7a5a614 station: allow connections to Hotspot networks
After a scan, station can now pause future scans and start ANQP requests
to discover Hotspot's NAI realm. This lets us check if the AP's NAI realm
matches any stored hotspot configuration files. If so we can connect to
this network. If the network provides an HESSID and a matching one is
found in a hotspot provisioning file we can skip ANQP and directly connect
as this is expected to be our 'home network'

0bde59ca13 anqp: move request functionality into anqp.c
The actual ANQP request was handled by netdev, but in the case of P2P
their may be no netdev. For this reason all functionality needed for
an ANQP request has been moved into anqp.c. There are still a few netdev
references, which need to be removed when P2P is introduced. Leaving them
in for now as its still going to work as a first pass implementation

537fcd12ca anqp: rework NAI Realm parsing
The initial ANQP parser design did not work well with how the hotspot
implementation was turning out. For one, much care was taken into parsing
the EAP credentials which are not really required. The assumption is
that any hotspot network will already be provisioned, so checking that
the EAP parameters match is a bit overkill. Instead only the NAI Realms
will be checked. This greatly simplifies the NAI realm parser, as now it
can just return a string list of realms instead of the full EAP
credential info.

a5f2710d05 hotspot: add hotspot module

stored under the .hotspot/ directory. This includes a dir watch to
handle file changes/removal as well as an API to match a network

273f0d358b doc: add disable_anqp option
The way IWD does ANQP depends on a recent kernel patch so its best if
we have ANQP disabled by default. In addition it has been found some
drivers do public action frames very badly, resulting in freezes or
crashes. If users are feeling brave, or are confident they're system
can handle ANQP properly they can enable this.

Enabling this option is required for Hotspot 2.0 support

701a5cc41e network: store HESSID and NAI Realms in network object
Hotspot networks are supposed to include an HESSID in the scan
results. This is more or less an identifier for the overall
network. In addition, the NAI Realms can be obtained via ANQP
and should be the same for each BSS. Since both HESSID and NAI
realms should be the same for a given network in range we can
store these values in the network object itself. This also allows
us to easily find hotspot configuration files by looking at
the HESSID/NAI Realms directly in the network object as opposed
to individual scan_bss's.

d63c8290a9 scan: add suspend/resume scan APIs
In order to do ANQP efficiently IWD needs the ability to suspend scanning
temporarily. This is because both scanning and ANQP go offchannel and must
remain off channel for some amount of time. This cannot be done
simultaneously and if e.g. ANQP is requested after a scan is already
pending, the kernel will wait till that scan finishes before sending out
the frame.

f0848cc44a rtnlutil: Don't use explicit_bzero
Use memset instead.  explicit_bzero should only be used when we're
wiping a secret just prior to the encopassing storage being freed.  The
compiler would usually optimize away the memset, leaving the secrets
around.

In rtnlutil we're simply zeroing the structure prior to filling it, so
the use of explicit_bzero is not needed and brings confusion to the
reader since no secrets are being wiped.

b70ff5d091 netconfig: Add station state watch
netconfig is interested in three station states: connected,
disconnected and connected after it has roamed. On connected
it tries to obtain a new DHCP lease, on disconnected it stops
the DHCP client and discards all addresses from interface, on
connected after roaming it will try to request a previously
issued address.
