Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply. Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start. Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.
The disconnect event handler was mistakenly bailing out if FT or
reassociation was going on. This was done because a disconnect
event is sent by the kernel when CMD_AUTH/CMD_ASSOC is used.
The problem is an AP could also disconnect IWD which should never
be ignored.
To fix this always parse the disconnect event and, if issued by
the AP, always notify watchers of the disconnect.
Passing *args, **kwargs into StationDebug ended up initializing the
class with Station properties since devices can be initialized from
existing property dictionaries. Since the object path is all
StationDebug needs, pass args[0] instead.
LLD 13 and GNU ld 2.37 support -z start-stop-gc which allows garbage
collection of C identifier name sections despite the __start_/__stop_
references. GNU ld before 2015-10 had the behavior as well. Simply set
the retain attribute so that GCC 11 (if configure-time binutils is 2.36
or newer)/Clang 13 will set the SHF_GNU_RETAIN section attribute to
prevent garbage collection.
Without the patch, there are linker errors with -z start-stop-gc
(LLD default) when -Wl,--gc-sections is used:
```
ld.lld: error: undefined symbol: __start___eap
>>> referenced by eap.c
>>> src/eap.o:(eap_init)
```
The remain attribute will not be needed if the metadata sections are
referenced by code directly.
Document the new API that clients can use to get notified of new network
configuration and be responsible for committing it to the netdev, the
resolver, etc.
On some systems the default radvd pid file location is not accessible.
Specify it to be under /tmp instead.
While there, enable full radvd debug output so it is logged when
test-runner is invoked with the --log option.
ap.c has been mostly careful to call the event handler at the end of any
externally called function to allow methods like ap_free() to be called
within the handler, but that isn't enough. For example in
ap_del_station we may end up emitting two events: STATION_REMOVED and
DHCP_LEASE_EXPIRED. Use a slightly more complicated mechanism to
explicitly guard ap_free calls inside the event handler.
To make it easier, simplify cleanup in ap_assoc_reassoc with the use of
_auto_.
In ap_del_station reorder the actions to send the STATION_REMOVED event
first as the DHCP_LEASE_EXPIRED is a consequence of the former and it
makes sense for the handler to react to it first.
src/eap.c: In function 'eap_rx_packet':
src/eap.c:419:50: error: 'vendor_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
419 | (type == EAP_TYPE_EXPANDED && vendor_id == (id) && vendor_type == (t))
| ^~
src/eap.c:430:11: note: 'vendor_type' was declared here
430 | uint32_t vendor_type;
It isn't clear why GCC complains about vendor_type, but not vendor_id.
But in all cases if type == EAP_TYPE_EXPANDED, then vendor_type and
vendor_id are set. Silence this spurious warning.
There is an unchecked NULL pointer access in network_has_open_pair.
open_info can be NULL, when out of multiple APs in range that advertise
the same SSID some advertise OWE transition elments and some don't.
A user reported a crash in situations where there was an OWE transition
pair, with an extra open network using the same SSID but not advertising
the OWE transition IE:

The Hotspot 2.0 spec has some requirements that IWD was missing depending
on a few bits in extended capabilities and the HS2.0 indication element.
These requirements correspond to a few sysfs options that can be set in
the kernel which are now set on CONNECTED and unset on DISCONNECTED.
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.
