c4b2f10483 manager: Handle missing NEW_WIPHY events
The kernel emits NEW_WIPHY events whenever a new wiphy is registered.
Unfortunately these events are emitted under the 'legacy' semantics and
have a hard size limit of 4096 bytes.  Unfortunately, it is possible for
a NEW_WIPHY message to exceed this limit (ath10k cards seem to be
affected in particular), which results in the kernel never sending these
messages out.  This can lead to NEW_INTERFACE events being emitted with
a wiphy_id that had no corresponding NEW_WIPHY event emitted.  Such a
sequence can confuse iwd's hardware detection logic, particularly during
hot-plug or system boot.

Fix this by re-dumping the wiphy if such a condition is detected.  This
has some interaction with blacklisted wiphys, so the wiphy objects are
now always tracked and marked as blacklisted.  Before, the blacklisted
wiphys were simply not added to the iwd list of tracked wiphys.

c2078c703d eap-tls-common: Address PEAPv0 interoperability with Windows
Windows Server 2008 - Network Policy Server (NPS) generates an invalid
Compound MAC for Cryptobinding TLV when is used within PEAPv0 due to
incorrect parsing of the message containing TLS Client Hello.
Setting L bit and including TLS Message Length field, even for the
packets that do not require fragmentation, corrects the issue. The
redundant TLS Message Length field in unfragmented packets doesn't
seem to affect the other server implementations.

55f9639ee3 manager: Retry the interface setup if we get an EBUSY
Sometimes, at least with brcmfmac, the default interface apparently
takes a moment to get created after the NEW_WIPHY event.  We didn't
really consider this case in the NEW_WIPHY handler and we've got a race
condition.  It fixes the following bug for me:
https://bugs.archlinux.org/task/63912 -- tested by removing and
re-modprobing the brcmfmac module rather than rebooting.

To work around this wait for the NEW_INTERFACE event and then retry the
setup.  We still do the initial attempt directly after NEW_WIPHY to
handle cases like wiphys with no default interfaces and pre-existing
wiphys.

03ccc454b7 knownneetworks: React to mtime updates
We track mtime as the 'LastConnectedTime' of the network, and also sort
the known network list according to the last connected time.
Unfortunately we were never reacting to ATTRIB changes, and so were
never updating the network_info->connected_time whenever a network was
connected to.

Rework the logic to address this.  This also fixes a small bug where the
connected_time was not set properly prior to removal / re-insertion of
the network_info.

98e1d38056 monitor: Fix crash
NLMSG_OK and NLMSG_NEXT expect to operate on nlmsg_len which is an int
(signed type).  The current code uses an unsigned type which means that
it cannot detect underflows.  Such underflows can happen when NLMSG_NEXT
tries to advance nlmsg_len by a number of bytes (due to alignment) which
are greater than the current nlmsg_len itself.  This causes iwmon to
crash on certain messages.

681172a999 storage: Add ability to preserve times
We use the mtime on the network profile as the 'Last Connected Time'.
When we update any property and sync the file to disk, the mtime was not
preserved (since we were creating a new temporary file instead of
modifying the old one).  This led to LastConnectedTime property change
being emitted / updated incorrectly when a writable property on the
KnownNetwork interface was updated.

ec15838215 wsc: Rework wsc_enrollee_destroy
Our design preference is to not call any callbacks in the _free/_destroy
method of a class (with the exception of explicit destroy callbacks
provided, if any).

Invoking the callback in this case was unnecessary: wsc_dbus_free was
already replying to pending connect / cancel messages.  The only other
thing the callback would attempt to do is to set station back into
autoconnect mode.  This was unnecessary as well since the netdev is
already down.

This change removes the callback invocation.  Since wsc_enrollee_destroy
is now just calling wsc_enrollee_free, remove this from the API and
expose wsc_enrollee_free instead.

ce16ba3bf8 wsc: Refactor WSC D-Bus interface logic
Split the WSC D-Bus interface class (struct wsc) into a base class

specific logic like scanning, saving the credentials as a known network
and triggering the station-mode connection (struct wsc_station_dbus).

Make the base class and its utilities public in wsc.h for P2P use.

b10264dcc7 wsc: Split out enrollee state machine to own object
Create struct wsc_enrollee which is allocated with wsc_enrollee_new,
taking a done callback as a parameter.  The callback is always
called so there's no need for a separate destroy callback.  The object
only lives until the done callback happens so wsc_enrollee_cancel/destroy
can only be used before this.

Looks like the rest of the file is simplified thanks to this.

6484b7dbb6 Add a new frame watch API
This new API is independent of netdev.c and allows actually
unregistering from receiving notifications of frames, although with some
quirks.  The current API only allowed the callback for a registration to
be forgotten but our process and/or the kernel would still be woken up
when matching frames were received because the kernel had no frame
unregister call.  In the new API you can supply a group-id paramter when
registering frames.  If it is non-zero the frame_watch_group_remove() call
can be used to remove all frame registrations that had a given group-id
by closing the netlink socket on which the notifications would be
received.  This means though that it's a slightly costly operation.

The file is named frame-xchg.c because I'm thinking of also adding
utilities for sending frames and waiting for one of a number of replies
and handling the acked/un-acked information.

Network Index     R     Deprecated - use fixed value 1 for
                        backwards compatibility.

Network Key       O     Deprecated. Only included by WSC 1.0

c93a4d71d6 test-runner: add special radius_server key
Some test cases require (at least with recent hostapd versions) a
stand alone radius server. This is done using driver=none in the
hostapd config file. For this use case hostapd does not need any
radio since its not doing anything wireless related.

Now inside the hw.conf file, under the HOSTAPD group, you can
specify a config file as the value to 'radius_server' key. This
config file will be used without any associated radio when hostapd
is started.

3607ee0c7e netdev: Allow both -EOPNOTSUPP and -ENOTSUPP
It seems that the kernel uses -EOPNOTSUPP if the change_station
operation is not implemented by the driver.  However, some drivers do
implement change_station and choose to report -ENOTSUPP instead of
-EOPNOTSUPP.

To add to the confusion, EOPNOTSUPP and -ENOTSUPP are the same on some
systems (e.g. Gentoo).  Be paranoid and allow both errors to be ignored
when sending CMD_SET_STATION.
