Netconfig was the only user of sysfs but now other modules will
also need it.
Adding existing API for IPv6 settings, a IPv4 and IPv6 'supports'
checker, and a setter for IPv4 settings.
If a beacon is lost testAP will fail since it did not utilize any
rescanning logic. Now it can use this feature by passing full_scan.
This is required since IWD APs are not known to test-runner like
hostapd APs are.
Certain scenarios coupled with lost beacons could result in OrderedNetwork
being initialized many times until the dbus library reached its maximum
signal registrations. This could happen where there are two networks,
IWD finds one in a scan but continues to scan for the other and the beacons
are lost. The way get_ordered_networks was written it returns early if any
networks are found. Since get_ordered_network (not plural) uses
get_ordered_networks() in a loop this caused OrderedNetwork's to be created
rapidly until python raises an exception.
To fix this, pass an optional list of networks being looked for to
get_ordered_networks. Only if all the networks in the list are found will
it return early, otherwise it will continue to scan.
In non-interactive mode, when a dbus method call returns the process
exits. This is true for all methods except agent requests since e.g.
Connect() call automatically requests credentials and the client must
wait for that to return before exiting. The new daemon interface must
also be treated in the same way and not exit.
It appears different versions of pyroute2 may or may not have
iwutil, and instead use pyroute2.IW() directly. Try the iwutil
way first, then pyroute2.IW()
The way a SA Query was done following a channel switch was slightly
incorrect. One because it is only needed when OCVC is set, and two
because IWD was not waiting a random delay between 0 and 5000us as
lined out by the spec. This patch fixes both these issues.
When station 'show' is invoked, parse and print any IP addresses
associated with the interface.
If iwd network configuration is disabled and no IP addresses were
configured, print a hint to the user that a DHCP client might need to be
configured.
Commit ed10b00afa ("unit: Fix eapol IP Allocation test failure")
did not convert all instances of IP allocation settings to network byte
order.
Fixes: 5c9de0cf23 ("eapol: Store IP address in network byte order")
Cache the latest v4 and v6 domain string lists in struct netconfig state
to be able to more easily detect changes in those values in future
commits. For that split netconfig_set_domains's code into this function,
which now only commits the values in netconfig->v{4,6}_domain{,s} to the
resolver, and netconfig_domains_update() which figures out the active
domains string list and saves it into netconfig->v{4,6}_domain{,s}. This
probably saves some cycles as the callers can now decide to only
recalculate the domains list which may have changed.
While there simplify netconfig_set_domains return type to void as the
result was always 0 anyway and was never checked by callers.
Cache the latest v4 and v6 DNS IP string lists in struct netconfig state
to be able to more easily detect changes in those values in future
commits. For that split netconfig_set_dns's code into this function,
which now only commit the values in netconfig->dns{4,6}_list to the
resolver, and netconfig_dns_list_update() which figures out the active
DNS IP address list and saves it in netconfig->dns{4,6} list. This
probably saves some cycles as the callers can now decide to only
recalculate the dns_list which may have changed.
While there simplify netconfig_set_dns return type to void as the result
was always 0 anyway and was never checked by callers.
Cache the latest v4 and v6 gateway IP string in struct netconfig state
to be able to more easily detect changes in those values in future
commits and perhaps to simplify the ..._routes_install functions.
netconfig_ipv4_get_gateway's out_mac parameter can now be NULL. While
editing that function fix a small formatting annoyance.
Use a separate fils variable to make the code a bit prettier.
Also make sure that the out_mac parameter is not NULL prior to storing
the gateway_mac in it.
Add netconfig_enabled() and use that in all places that want to know
whether network configuration is enabled. Drop the enable_network_config
deprecated setting, which was only being handled in one of these 5 or so
places.
This code path was never tested and used to ensure a OWE transition
candidate gets selected over an open one (e.g. if all the BSS's are
blacklisted). But this logic was incorrect and the path was being
taken for BSS's that did not contain the owe_trans element, basically
all BSS's. For RSN's this was somewhat fine since the final check
would set a candidate, but for open BSS's the loop would start over
and potentially complete the loop without ever returning a candidate.
If fallback was false, NULL would be returned.
To fix this only take the OWE transition path if its an OWE transition
BSS, i.e. inverse the logic.
There was no open ssid provisioning file, which was fine as the
first test should have created one. But to be safe, include one
explicitly and use the proper setUp/tearDown functions.
Normally Beacon Reporting subelements are present only if repeated
measurements are requested. However, an all-zero Beacon Reporting
subelement is included by some implementations. Handle this case
similarly to the absent case.
Since Reporting Detail subelement is listed as 'extensible', make sure
that the length check is not overly restrictive. We only interpret the
first field.
It was seen during testing that several offload-capable cards
were not including the OCI in the 4-way handshake. This made
any OCV capable AP unconnectable.
To be safe disable OCV on any cards that support offloading.
802.11 requires an STA initiate the SA Query procedure on channel
switch events. This patch refactors sending the SA Query into its
own routine and starts the procedure when the channel switch event
comes in.
In addition the OCI needs to be verified, so the channel info is
parsed and set into the handshakes chandef.
There are several events for channel switching, and nl80211cmd was
naming two of them "Channel Switch Notify". Change
CH_SWITCH_STARTED_NOTIFY to "Channel Switch Started Notify" to
distinguish the two events.
By sleeping for 4 seconds IWD had plenty of time to fully disconnect
and reconnect in time to pass the final "connected" check. Instead
use wait_for_object_condition to wait for disconnected and expect
this to fail. This will let the test fail if IWD disconnects.
SA query is the final protocol that requires OCI inclusion and
verification. The OCI element is now included and verified in
both request and response frames as required by 802.11.
