Isolate the known_frequency queue management to a function and place
that function in knownnetworks.c where it now belongs. Since we no
longer have network_info objects for unknown networks, only frequencies
for known networks are tracked
networks queue was intended to share basic network information between
multiple adapters running simultaneously. The network_info object was
also serving double duty to carry known network information. This made
things overly complicated and really didn't result in much savings.
This setup also made managing hotspot networks challenging as we would
have ended up with multiple network_info objects for each known hotspot
network.
So get rid of the networks queue and the is_known bit from the
network_info structure.
network_find_rank_index was used to find the offset of the selected
network_info among known networks so as to compute a modifier based on
the rankmod table. Instead of using known_networks_foreach for this,
moove it to knownnetworks.c where it can be coded and optimized
separately.
For now provide a simple for loop implementation.
This will allow the user to see the iwd output in /tmp/iwd.log.
execute_program was extended to take a 'log' flag. If true, this
will cause the programs output to be stored in /tmp/<name>.log.
This is only useful when using the --shell command as this file
will go away once the VM stops. The verbose flag always overrides
the logging functionality.
For now only iwd output is logged when using --shell.
This is merely an empty test that can act as a sandbox for the new
--shell command. It was not named with 'test' so that autotesting
will skip it.
This test is not very useful for virtual hardware testing
(mac80211_hwsim), but very useful for USB/PCI passthrough. When
setup correctly, you can now pass through a single device and test
against real networks with a minimal kernel.
It is sometimes valuable to just boot into a shell in order to manually
test functionality. Since test-runner already is setup to run a minimal
kernel with all the necessary requirements for hostapd/iwd it made
sense to allow the user to do this.
If -s,--shell is passed into test runner, no python tests will be run.
The hw.conf file is still used to setup IWD and hostapd so once booted
into the shell you can still (manually) run the test (e.g. via iwctl).
This also works when using USB/PCI passthrough. This makes testing
out different kernel version with real hardware much quicker than
using the host kernel.
Doing this scan causes issues in the test. Like with other autoconnect
tests we can just use the fact that IWD will always be doing a periodic
scan during start up, so we only need to wait for that to finish before
querying the network list.
Previously, the option PrivateDevices=true disabled access to
/dev/rfkill, which lead to:
'iwctl adapter phy0 set-property Powered {off|on}'
to fail.
This patch explicitly allows access to /dev/rfkill
src/rtnlutil.c: In function ‘rtnl_route_add’:
./ell/util.h:248:2: error: ‘rtmmsg’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
Instead of using a flag ipv4_static, just store the value of the rtm
protocol directly inside netconfig object. This allows us to simplify
the logic quite significantly and avoid repeating the conditional
expression needlessly
The routes are installed as a result of a successful installation
of the IP addresses. The gateway is fetched with netconfig_ipv4_get_gateway
helper function according to the origin of the installed IP address.
The route priority offset can be set in main.conf. The default value
of 300 is used if the offset isn’t set.
The API allows to add connected and gateway routes to the main
routing table.
rtnl_route_ipv4_add_gateway() is equivalent to the following
example 'ip route' command:
ip route add default via 10.0.0.1 dev wlan0 proto dhcp src 10.0.0.2 metric 339
rtnl_route_ipv4_add_connected() is equivalent to the following
example 'ip route' command:
sudo ip route add 10.0.0.0/24 dev wlan0 proto dhcp src 10.0.0.2 scope link
The 'ip route' output from the above commands looks as follows:
rtnl_route_ipv4_add_connected():
10.0.0.0/24 dev wlan0 proto dhcp scope link src 10.0.0.2
rtnl_route_ipv4_add_gateway():
default via 10.0.0.1 dev wlan0 proto dhcp src 10.0.0.2 metric 339
The DNS addresses are installed as a result of a successful
installation of the IP addresses. The DNS lists are fetched
with netconfig_ipv4_get_dns helper function according to the
origin of the installed IP address.
iwd reconfigures the wireless interfaces with respective
connection events. Each supported network protocol is
reconfigured. The address for each protocol is
selected as static or dynamic based on availability.
netconfig_ipv4_get_ifaddr helper function allows to fetch IPv4
addresses from static or dynamic sources. The origin of the addresses
is noted in 'ipv4_is_static' flag.
