A comma separated list as a string was ok for pure display purposes
but if any processing needed to be done on these values by external
consumers it really makes more sense to use a DBus array.
This wasn't being updated meaning the property is missing until a
scan is issued over DBus.
Rather than duplicate all the property changed calls they were all
factored out into a helper function.
Adds the MulticastDNS option globally to main.conf. If set all
network connections (when netconfig is enabled) will set mDNS
support into the resolver. Note that an individual network profile
can still override the global value if it sets MulticastDNS.
The limitation of cipher selection in ap.c was done so to allow p2p to
work. Now with the ability to specify ciphers in the AP config put the
burden on p2p to limit ciphers as it needs which is only CCMP according
to the spec.
These can now be optionally provided in an AP profile and provide a
way to limit what ciphers can be chosen. This still is dependent on
what the hardware supports.
The validation of these ciphers for station is done when parsing
the BSS RSNE but for AP mode there is no such validation and
potentially any supported cipher could be chosen, even if its
incompatible for the type of key.
The netdev_copy_tk function was being hard coded with authenticator
set to false. This isn't important for any ciphers except TKIP but
now that AP mode supports TKIP it needs to be fixed.
Though TKIP is deprecated and insecure its trivial to support it in
AP mode as we already do in station. This is only to allow AP mode
for old hardware that may only support TKIP. If the hardware supports
any higher level cipher that will be chosen automatically.
The key descriptor version was hard coded to HMAC_SHA1_AES which
is correct when using IE_RSN_AKM_SUITE_PSK + CCMP. ap.c hard
codes the PSK AKM but still uses wiphy to select the cipher. In
theory there could be hardware that only supports TKIP which
would then make IWD non-compliant since a different key descriptor
version should be used with PSK + TKIP (HMAC_MD5_ARC4).
Now use a helper to sort out which key descriptor should be used
given the AKM and cipher suite.
Similarly to l_netconfig track whether IWD's netconfig is active (from
the moment of netconfig_configure() till netconfig_reset()) using a
"started" flag and avoid handling or emitting any events after "started"
is cleared.
This fixes an occasional issue with the Netconfig Agent backend where
station would reset netconfig, netconfig would issue DBus calls to clear
addresses and routes, station would go into DISCONNECTING, perhaps
finish and go into DISCONNECTED and after a while the DBus calls would
come back with an error which would cause a NETCONFIG_EVENT_FAILED
causing station to call netdev_disconnct() for a second time and
transition to and get stuck in DISCONNECTING.
Both CMD_ASSOCIATE and CMD_CONNECT paths were using very similar code to
build RSN specific attributes. Use a common function to build these
attributes to cut down on duplicated code.
While here, also start using ie_rsn_cipher_suite_to_cipher instead of
assuming that the pairwise / group ciphers can only be CCMP or TKIP.
Instead of copy-pasting the same basic operation (memcpy & assignment),
use a goto and a common path instead. This should also make it easier
for the compiler to optimize this function.
The known frequency list may include frequencies that once were
allowed but are now disabled due to regulatory restrictions. Don't
include these frequencies in the roam scan.
These events are sent if IWD fails to authentiate
(ft-over-air-roam-failed) or if it falls back to over air after
failing to use FT-over-DS (try-ft-over-air)
If IPv4 setup fails and the netconfig logic gives up, continue as if the
connection had failed at earlier stages so that autoconnect can try the
next available network.
