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.
This change removes duplicate calls to display_table_footer(), in
station show.
Before this change, the bug caused an extra newline to be output every
time the table updated. This only occurred when the network was
disconnected.
$ iwctl
[iwd]# station wlan0 show
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.
The disabled cipher list contained a '.' instead of ',' which prevented
the subsequent ciphers from being disabled. This was only group management
ciphers so it didn't have any effect on the test.
The -F option is undocumented but allows you to pass a nl80211
family ID so iwmon doesn't ignore messages which don't match the
systems nl80211 family ID (i.e. pcaps from other systems).
This is somewhat of a pain to use since its unclear what the other
system's family ID actually is until you run it though something
like wireshark. Instead iwmon can ignore the family ID when in
read mode which makes reading other systems pcap files automatic.
Expand nlmon_create to be useful for both pcaps and monitoring. Doing
this also lets iwmon filter pcaps based on --no-ies,rtnl,scan etc
flags since they are part of the config.
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 __str__ function assumed station mode which throws an exception
if the device is in AP mode. Fix this as well as print out the mode
the device is in.
This API optimizes scanning to run tests quickly by only scanning
the frequencies which hostapd is using. But if a test doesn't use
hostapd this API raises an uncaught exception.
Check if hostapd is being used, and if not just do a full scan.
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.
Add an additional optional PairwiseCipher property on
net.connman.iwd.StationDiagnostic interface that will hold the current
pairwise cipher in use for the connection.
