For Radio Resource Management (RRM) we will need access to the currently
connected BSS as well as the last scan results in order to do certain
kinds of requested measurements.
Hostapd has a feature where you can connect to its control socket and
receive events it generates. Currently we only send commands via this
socket.
First we open the socket (/var/run/hostapd/<iface>) and send the
ATTACH command. This tells hostapd we are ready and after this any
events will be sent over this socket.
A new API, wait_for_event, was added which takes an event string and
waits for some timeout. The glib event loop has been integrated into
this, though its not technically async since we are selecting over a
socket which blocks. To mitigate this a small timeout was chosen for
each select call and then wrapped in a while loop which waits for the
full timeout.
All the processes verbose output is just written to stdout, and very
hard to parse after the test runs. Having test-runner write the
processes output to separate log files is much nicer to view after
the test runs.
A read/write file system is created which is separate and isolated
from the current FS mount (which mounts the whole host file system).
Doing this requires the user to create a folder somewhere to be used
as the mount point. This folder is where all the log files will end
up after test-runner runs.
Since test-runner must be run as root, care was taken to keep the
log files owned by the user which runs test-runner. The UID/GID
are passed to the VM, and any log files created are chown'ed back
to the user who ran test-runner.
execute_program was refactored, and both verbose and log arguments
were removed. The verbose argument was not really required since
we can do check_verbosity(argv[0]) internally. The 'log' flag was
only used along with --shell, and now the user can simply use
--log instead of dumping /tmp/iwd.log.
You can use this feature by specifying --log[=path] to test-runner.
If no path is provided the current directory will be used. Using
the --log flag will result in all processes being run with the
--verbose flag.
A new folder will be created under the --log path. The folder will
be of the name "run-<year>-<month>-<dat>-<PID>". Under this folder
you will find any global process logs. These are processes that
are only run once for ALL tests (hwsim, ifconfig, dbus etc.). There
will also be folders for specific tests that were run. Inside these
test folders will be logs of processes that are run per-test (iwd,
hostapd, python etc.).
netdev_connect can achieve the same effect as netdev_connect_wsc but is
more flexible as it allows us to supply additional association IEs. We
will need this capability to make P2P connections. This way we're also
moving the WSC-specific bits to wsc.c from the crowded netdev.c.
On EAP events, call the handshake_event handler with the new event type
HANDSHAKE_EVENT_EAP_NOTIFY isntead of the eapol_event callback.
This allows the handler to be set before calling
netdev_connect/netdev_connect_wsc. It's also in theory more type-safe
because we don't need the cast in netdev_connect_wsc anymore.
Convert the handshake event callback type to use variable argument
list to allow for more flexibility in event-specific arguments
passed to the callbacks.
Note the uint16_t reason code is promoted to an int when using variable
arguments so va_arg(args, int) has to be used.
no_cck_rates is set in the scan parameters generally to make sure
that the Probe Request frames are not sent at any of the 802.11b
rates during active scans. With this patch we also omit those rates
from the Supported Rates IEs, which is required by the p2p spec and
also matches our flag's name.
Keep cursor's position consistent when passphrase is reaching
its maximum by adding characters in the middle of the string
The use case is very rare as not many people will attempt to
modify the masked passphrase from the middle.
Its difficult to know 100%, but this random test failures appeared
to be caused by two issues. One was that get_ordered_network is being
checked for None, when it was returning a zero length array. Because
of this the scanning block was never executed in any cases. This was
fixed in the previous commit. The other issue was the disconnect at
the start of the tests. The disconnect will cause all pending scans
to cancel, which appeared to cause the scanning block below to be
skipped over quickly if the timing was right. Then, afterwards,
getting a single network failed because scanning was not complete.
If no networks are found, return None rather than an empty
array. This is easier to check by the caller (and was assumed
in some cases). Also add an exception to get_ordered_network
if no network is found.
Previously, CTRL+D used to cause termination of the client. Now, the
command will cancel the agent’s prompts in agent mod. In regular mode
the behavior is unchanged.
The current logic did not make sure that each entry provided was
actually parsed. Also add a sanity check to make sure that no duplicate
parsing occurs.
