a716f46573 netdev: Replace bool randomize_mac with specific address
Allow netdev_create_from_genl callers to draw a random or non-random MAC
and pass it in the parameter instead of a bool to tell us to generating
the MAC locally.  In P2P we are generating the MAC some time before
creating the netdev in order to pass it to the peer during negotiation.

d9efacfbba peap: Ignore Crypto-Binding TLVs with invalid compound MACs
Some server implementation don't seem to provide the valid compound MACs.
In the meantime, iwd will ignore the invalid Crypto-Binding TLVs as their

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.

8884fd8bbd peap: Add support for Crypto-Binding in PEAPv0
The Crypto Binding TLV is used to ensure that the EAP peer and the
EAP server participated in both the inner and the outer EAP
authentications of a PEAP authentication by cryptographically associating
the phase 1 and phase 2 authentications.

The usage of Crypto-Binding in PEAPv0 is optional and is triggered by
the reception of the Crypto-Binding TLV from the server.

d510f332b6 eap-gtc: Try to auth even if request not Password
There are some server implementations that send requests that are

738184d491 device/netdev: init scan in netdev instead of device
Commit 1057d8aa74 changed the device interface creation logic
from being unconditional inside netdev.c to instead use NETDEV_WATCH_*
events.  However, this broke the assumption that the device interface
was created before all others.  The effect is that the scan_wdev_add
might no longer be called prior to station interface being created.  Fix
this by moving scan_wdev_add/remove calls to netdev.c instead.

1d57ec0d46 scan: Parse P2P IEs according to frame type
Save the source frame type in struct scan_bss as it may affect how some
of the data in the struct will be parsed.  Also replace the P2P IE
payload data in that struct with a union containing pre-parsed p2p
attributes corresponding to the frame type.

This means users don't have to call the parsers in p2putil.c on that
data, which wouldn't have worked anyway because those parsers assume
input is the raw IE sequence rather than just the "payload".

27af5b715e scan: parse the scan start time
The kernel sends NL80211_ATTR_SCAN_START_TIME_TSF with CMD_TRIGGER and
RRM requires this value for beacon measurement reports.

The start time is parsed during CMD_TRIGGER and set into the scan request.
A getter was added to obtain this time value for an already triggered
scan.

After making the change, the SCAN_ABORTED case was cleaned up a bit to
remove the local scan_request usage in favor of the one used for all the
other cases.

request.

1f01819c70 rrm: add radio resource management module
This module takes care of radio measurements which an AP can request.
There are many types of requests, and for now only beacon requests
are supported.

IWD will filter certain types of beacon requests that are NOT
supported:

 - AP channel reports. Only single channel requests will be supported
 - Autonomous measurements. Only direct requests will be supported.
   IWD will not accept requets to trigger reports under certain
   conditions (SNR/RSSI thresholds, etc.)
 - Timed measurements. Only immediate measurements will be performed.
   The accuracy for timed measurements cannot be reliably guaranteed
   due to kernel scheduling/queues.
 - Full reporting detail. The AP can request the STA return the full
   set of IEs in a beacon. IWD does not currently save all IEs, plus
   there is quite a bit of complexity involved as certain IEs get
   truncated, and there are other length limitations.

There are other limitations not specific to beacon requests:

 - IWD will support single measurement requests per report. Multiple
   measurement request IEs can be included, but the reports will be
   sent out separately.

 - IWD will limit the number of requests it responds to in a given
   amount of time. As it stands now this is hard coded to 2 requests
   per second maximum. This will prevent DoS attacks.

 - IWD will not accept any measurement requests from APs it is not
   connected to, and will not accept any requests until connected.

0d7fbfe523 network: add L_WARN for known network lookup failure
When updating the network ranking there was a potential out of bounds
array access. The condition was if known_network_offset returned a
negative value, indicating the known network was not found. Since
network->info is only set for known networks this should not ever
happen as network->info is checked prior.

Though this is likely impossible, knownnetworks is complex enough that
its better to just be paranoid and put an L_WARN_ON to check the
return.

45bd459711 eap-tls-common: Relax certificate chain check
Relax the pre-check for local user certificate.  Before we used to check
that the CA provided (if any) was used to verify both the peer identity
and the local certificate chain.  However, there seem to be networks
that use different CAs to sign AP/Radius certificates and certificates
issued to users.

Drop the ca_certs argument from l_certchain_verify, but keep the call
there to make sure the certificate chain is indeed a chain as a sanity
check.

3f2b558f57 sae: fix potential integer overflow
If an authentication frame of length <= 5 is sent sae will overflow an
integer. The original cause of this was due to incorrectly using the
sizeof(struct mmpdu_header). The header can be either 24 or 28 bytes
depending on fc.order. sizeof does not account for this so 28 is always
the calculated length.

This, in addition to hostapd not including a group number when rejecting,
cause this erroneous length calculation to be worked around as seen in
the removed comment. The comment is still valid (and described again
in another location) but the actual check for len == 4 is not correct.

To fix this we now rely on mpdu_validate to check that the authentication
frame is valid, and then subtract the actual header length using
mmpdu_header_len rather than sizeof. Doing this lets us also remove the
length check since it was validated previously.

0d9c9274d9 eapol: do not parse RSN for WPA1 in 1 of 4
A recent change checked the return value of ie_parse_rsne_from_data
inside the ptk 1/4 handler. This seemed safe, but actually caused
the eapol unit test to fail.

The reason was because eapol was parsing the IEs assuming they were
an RSN, when they could be a WPA IE (WPA1 not WPA2). The WPA case
does not end up using the rsn_info at all, so having rsn_info
uninitialized did not pose a problem. After adding the return value
check it was found this fails every time for WPA1.

Since the rsn_info is not needed for WPA1 we can only do the RSN
parse for WPA2 and leave rsn_info uninitialized.

df8fc5f918 main: move module init into nl80211_appeared
In preparation for integrating IWD_MODULE into modules which require
nl80211 we move the module init into the nl80211_appeared callback.
This will guarentee that the nl80211 is available during module init
and allow modules to get their own copy of nl80211 rather than needing
a set function (e.g. netdev_set_nl80211).

Since the dbus name request callback happens before this as well any
dbus module can also use IWD_MODULE and simply assume the dbus object
is ready.

plugin_init was also deferred to nl80211_appeared since some plugins
depend on modules being initialized.

bea1d22a5c eap-tls-common: allow embedded PEMs in settings
Refactoring was required to allow for embedded certs. The existing
eap_tls_state object was changed to hold the cert types (l_queue,
l_certchain, l_key) rather than the file path, since there may not
actually be separate PEM files.

Care was taken to properly manage the memory of these objects.
Since the TLS object takes ownership when setting auth data or the
CA certs all error cases must be handled properly to free these
objects after they are loaded and in addition they must be set to
NULL so that the cleanup doesn't double free them.

If everything goes to plan, we load all the PEMs in settings_load,
provide these objects to the TLS APIs, and then NULL out the
pointers (TLS now owns this memory). If anything fails between
settings_load and l_tls_start we must free these objects.

A special format must be used to indicate that a PEM is embedded
inside the settings file. First, the l_settings format should be
followed for the PEM itself, e.g.

[@pem@my_ca_cert]
<CA Cert data>

This PEM can then be referenced by "embed:my_ca_cert", e.g.

EAP-TLS-CACert=embed:my_ca_cert

Any other value not starting with "embed:" will be treated as a file
path.

d954eee0cc netconfig: Change public API
As a first step to enable the usage of netconfig in ead and
prospective transition to be a part of ell, the public API for
creation and destruction of the netconfig objects has been
renamed and changed. Instead of hiding the netconfig objects inside
of netconfig module, the object is now passed back to the caller.
The internal queue of netconfig objects remains untouched, due
to limitations in ell’s implementation of rtnl. After the proper
changes are done to ell, netconfig_list is expected to be removed
from netconfig module.

95f1fb1663 manager: dump wiphy/iface on NEW_WIPHY
A NEW_WIPHY event may not always contain all the information about a
given phy, but GET_WIPHY will. In order to get everything we must
mimic the behavior done during initalization and dump both wiphy
and interfaces when a NEW_WIPHY comes in.

Now, any NEW_WIPHY event will initialize a wiphy, but then do a
GET_WIPHY/GET_INTERFACE to obtain all the information. Because of
this we can ignore any NEW_INTERFACE notifications since we are
dumping the interface anyways.

Once some kernel changes get merged we wont need to do this anymore
so long as the 'full' NEW_WIPHY feature is supported.

requires the raw passphrase to work, it makes sense to just store
the passphrase if we have it.

66346712e6 knownnetworks: make frequencies/UUID forgettable
Since the UUID was being generated purely on the file path, it
would never change for a given network (unless the SSID/name changed).
In the future we would like to use this unique UUID to generate a
MAC per-SSID, and if that network is forgotten we also want the UUID
to change next time the network is connected to.

Rather than only using the file path, the mtime can also be fed into
the UUID generation. Since the mtime would be changed after forgetting
and re-adding a known network we will get a new UUID.

Now, whenever a known network is removed, we lookup the UUID we have
in network_info and remove that entry in the settings file and
sync the frequency file.

f57b73898b knownnetwork: track/optimize UUID for known networks
The UUID was being generated every time we synced which is wasteful.
Instead we can track the UUID inside network_info and only generate
it once when needed.

Two new network_info APIs were added:
network_info_set_uuid
network_info_get_uuid

The setter is used when the frequency file is loaded. If a valid UUID
is found in the frequency file this UUID is set and used.

network_info_get_uuid will not just get the UUID, but actually generate
it if one has not been set yet. This will allow other modules to
get/generate the UUID if one has no been loaded from the frequency
file.

The extended capability bits were not being set properly inside

bytes are the IE type and length. The way we were setting the bits
did not take this into account and were actually setting the
completely wrong bits.

ef209c305b knownnetworks: make known frequencies its own module
The known frequency file was being loaded at the end of the known
networks initialization routine. This allowed all known networks
to be properly loaded, but since hotspot depends on known networks,
its initalization would be run afterwards meaning the frequency
loading would not have been finding any hotspot networks.

To fix this a new module was added inside known networks which
depends on hotspot. This means that first known networks will
initialize, then hotspot, then the frequency file would be loaded.

4eaf93d26a knownnetworks: rework known frequencies
The current format for the .known_networks.freq file had a hidden
limitation of not being able to handle SSID's with some special
characters. Since the provisioning file path was used as the
group name the filename was limited to only characters supported
by l_settings groups, which conflicted with allowable SSID
characters.

Instead we can generate a unique UUID for each network and use
this as the group. For this particular case the group does not
really matter, so long as its unique. But we can utilize this unique
UUID for other purposes, including using it as a seed for changing
the MAC address per-connection in the future.

The .known_networks.freq file will now have the following format:

[<UUID>]
name=/path/to/provisioning/file
list= XXXX YYYY ZZZZ

f5db4bfea8 network: sync frequencies per-network
The existing frequency syncing was done when IWD closes. Instead we
can sync as networks are connected to or promoted to known which

9ed5fba57b knownnetwork: add known_network_frequency_sync
This API will sync the known frequencies of a network_info object
to disk. This will allow network to sync known frequencies as
known networks are added, rather that when IWD closes.

Since this will result in more frequent syncing that before, the
known_freqs settings pointer was moved globally in knownnetworks.c
as to only parse the file one time rather than on every sync.
