These modules only needed to be imported a single time for the entire
run of tests. This is significantly cheaper in terms of memory and
should prevent random OOM exceptions.
The Procss class was doing quite a bit of what Popen already does like
storing the return code and process arguments. In addition the Process
class ended up storing a Popen object which was frequently accessed.
For both simplicity and memory savings have Process inherit Popen and
add the additional functionality test-runner needs like stdout
processing to output files and the console.
To do this Popen.wait() needed to be overridden to to prevent blocking
as well as wait for the HUP signal so we are sure all the process
output was written. kill() was also overritten to perform cleanup.
The most intrusive change was removing wait as a kwarg, and instead
requiring the caller to call wait(). This doesn't change much in
terms of complexity to the caller, but simplifies the __init__
routine of Process.
Some convenient improvements:
- Separate multiple process instance output (Terminate: <args> will
be written to outfiles each time a process dies.)
- Append to outfile if the same process is started again
- Wait for HUP before returning from wait(). This allows any remaining
output to be written without the need to manually call process_io.
- Store ctx as a class variable so callers don't need to pass it in
(e.g. when using Process directly rather than start_process)
Setter which forces the use of group 19 rather than the group order
that ELL provides. Certain APs have been found to have buggy group
negotiation and only work if group 19 is tried first, and only. When
an AP like this this is found (based on vendor OUI match) SAE will
use group 19 unconditionally, and fail if group 19 does not work.
Other groups could be tried upon failure but per the spec group 19
must be supported so there isn't much use in trying other, optional
groups.
mac80211_hwsim has a funny quirk with multiple addresses in
radios. Some operations require address index zero, some index
one. And these addresses (possibly a result of how test-runner
initializes radios) sometimes get mixed up. For example scan
results may show a BSS address as 02:00:00:00:00:00, while the
next test run shows 42:00:00:00:00:00.
Ultimately, sending out frames requires the first nibble of the
address to be 0x4 so to handle both variants of addresses described
above hwsim.py was updated to always bitwise OR the first byte
with 0x40.
Handle the 802.11ai FILS IP Address Assignment IEs in Association
Request frames when netconfig is enabled. Only IPv4 is supported.
Like the P2P IP Allocation mechanism, since the payload format and logic
is independent from the rest of the FILS standard this is enabled
unconditionally for clients who want to use it even though we don't
actually do FILS in AP mode.
If netconfig is enabled tell the DHCP server to expire any leases owned
by the client that is disconnecting by using l_dhcp_server_expire_by_mac
to return the IPs to the IP pool. They're added to the expired list
so they'd only be used if there are no other addresses left in the pool
and can be reactivated if the client comes back before the address is
used by somebody else.
This should ensure that we're always able to offer an address to a new
client as long as there are fewer concurrent clients than addresses in
the configured subnet or IP range.
Use the struct handshake_state::support_ip_allocation field already
supported in eapol.c authenticator side to enable the P2P IP Allocation
mechanism in ap.c. Add the P2P_GROUP_CAP_IP_ALLOCATION bit in P2P group
capabilities to signal the feature is now supported.
There's no harm in enabling this feature in every AP (not just P2P Group
Owner) but the clients won't know whether we support it other than
through that P2P-specific group capability bit.
Add a handshake event for use by the AP side for mechanisms that
allocate client IPs during the handshake: P2P address allocation and
FILS address assignment. This is emitted only when EAPOL or the
auth_proto is actually about to send the network configuration data to
the client so that ap.c can skip allocating a DHCP leases altogether if
the client doesn't send the required KDE or IE.
This test was failing due to a change introduced in commit
5c9de0cf23 which changed handshake state storage of IPs from host
order to network byte order. Update the test to set IPs in network
byte-order.
Fixes: 5c9de0cf23 ("eapol: Store IP address in network byte order")
Some drivers ignore the initial IF_OPER_UP setting that was sent during
netdev_connect_ok(). Attempt to work around this by parsing New Link
events. If OperState setting is still not correct in a subsequent event,
retry setting OperState to IF_OPER_UP.
The idea of this test is valid but it is extremely timing dependent
which simply isn't testable on all machines. Removing this test
at least until this can be tested reliably.
This was initially put in to solve an issue that was specific to
mac80211_hwsim where the connect callback would get queued and
delayed until after the connect event. This caused IWD to get very
confused.
Later it was found that "real" drivers can sometimes do this so
some code was added to IWD core to handle it.
Now there isn't much point to delay all frames unless a rule specifies
so change the behavior back to sending out frames immediately.
The hwsim Rule API was structured as properties so once a rule is
created it automatically starts being applied to frames. This happens
before anything has time to actually define the rule (source, destination
etc). This leads to every single frame being matched to the rule until
these other properties are added, which can result in unexpected behavior.
To fix this an "Enabled" property has been added and the rule will not
be applied until this is true.
The hotspot case can actually result in network being NULL which
ends up crashing when accessing "->secrets". In addition any
secrets on this network were never removed for hotspot networks
since everything happened in network_unset_hotspot.
testHotspot suffered from improper cleanup and if a single test failed
all subsequent tests would fail due to IWD still running since IWD()
was never cleaned up.
In addition the PSK agent and hwsim rules are now set onto the cls
object and removed in tearDownClass()
There are really no cases where a test wants to remove a single
rule. Most loop through and remove rules individually so this
is being added as a convenience.
Certain autotests coupled with slower test machines can result in lost
beacons and "Network not found" errors. In attempt to help with this
the test can just rescan (30 seconds max) until the network is found.
Remove EAP-SIM from the generic PEAP test case since skipping
(if ofono is not on system) would skip the entire test rather
than just the EAP-SIM portion.
This tests all EAP methods in their standard configuration. Any
corner cases requiring changes to main.conf or other hostapd
options are not included and will be left as stand alone tests.
This was done because nearly all EAP tests are identical except
the IWD provisioning file and hostapd EAP users fine. The IWD
provisioning file can be swapped out as needed for each individual
test without actually restarting IWD. And the EAP users file can
simply be written to include every possible EAP method that
is supported.
The -S/--sub-tests option allows the user to specify a test file
from inside an autotest. Inside this file there may also be many
test functions. This option is being extended to allow running
a single test function inside a test file. For example:
* Runs all test functions inside connection_test.py *
./test-runner -A some_test -S connection_test
* Runs only connection_test.py test_connect_success() *
./test-runner -A some_test -S connection_test.test_connect_success
The destructor was trying to do more than the scope of a destructor
by trying to handle this single case of hostapd being restarted.
Instead we can simply pass a keyword argument 'reinit' to the
constructor to tell it to reinitialize everything. And as for killing
hostapd this can be done in ungraceful_restart itself rather than
trying to handle it in the destructor.
There was a race condition here where the GLib timeout could have
fired but the test function returned successfully prior to the
end of the while loop. This would end up causing source_remove to
print a warning that the source did not exist.
Instead check if the timeout fired prior to removing it.
This (hopefully) will make this test pass better on slower machines.
In addition the mechanism of copying over separate main.conf files
was changed (rather than echo'ing the option into /tmp/main.conf)
This addresses the TODO where HostapdCLI was creating separate
objects each time HostapdCLI was called. This was worked around
by manually setting the important members but instead the class
can be re-worked to act as somewhat of a singleton, per-config
at least.
If there is no HostapdCLI instance for a given config one is
created and initialized. Subsequent HostapdCLI calls (for the
same config) will be returned the same object rather than a
new one.
