Since we use git ls-files to produce the list of all tests for -A, if
the source directory is owned by somebody other than root one might
get:
fatal: unsafe repository ('/home/balrog/repos/iwd' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /home/balrog/repos/iwd

Test that the DHCPv4 lease got renewed after the T1 timer runs out.
Then also simulate the DHCPREQUEST during renew being lost and
retransmitted and the lease eventually getting renewed T1 + 60s later.
The main downside is that this test will inevitably take a while if
running in Qemu without the time travel ability.
Update the test and some utility code to run hostapd in an isolated net
namespace for connection_test.py. We now need a second hostapd
instance though because in static_test.py we test ACD and we need to
produce an IP conflict. Moving the hostapd instance unexpectedly fixes
dhcpd's internal mechanism to avoid IP conflicts and it would no longer
assign 192.168.1.10 to the second client, it'd notice that address was
already in use and assign the next free address, or fail if there was
none. So add a second hostapd instance that runs in the main namespace
together with the statically-configured client, it turns out the test
relies on the kernel being unable to deliver IP traffic to interfaces on
the same system.
The kernel will not let us test some scenarios of communication between
two hwsim radios (e.g. STA and AP) if they're in the same net namespace.
For example, when connected, you can't add normal IPv4 subnet routes for
the same subnet on two different interfaces in one namespace (you'd
either get an EEXIST or you'd replace the other route), you can set
different metrics on the routes but that won't fix IP routing. For
testNetconfig the result is that communication works for DHCP before we
get the inital lease but renewals won't work because they're unicast.
Allow hostapd to run on a radio that has been moved to a different
namespace in hw.conf so we don't have to work around these issues.
The --start option was directly passed to the kernel init parameter,
preventing any environment setup from happening.
Intead always use 'run-tests' as the init process but detect --start
and execute that binary/script once inside the environment.
The table header needs to be adjusted to include spaces between
columns.
The 'adapter list' command was also updated to shorted a few
columns which were quite long for the data that is actually displayed.
The existing color code escape sequences required the user to set the
color, write the string, then unset with COLOR_OFF. Instead the macros
can be made to take the string itself and automatically terminate the
color with COLOR_OFF. This makes for much more concise strings.
ad-hoc, ap, and wsc all had descriptions longer than the max width but
this is now taken care of automatically. Remove the tab and newline's
from the description.
The WSC pin command description was also changed to be more accurate
since the pin does not need to be 8 digits.
There was no easy to use API for printing the contents of a table, and
was left up to the caller to handle manually. This adds display_table_row
which makes displaying tables much easier, including automatic support
for line truncation and continuation on the next line.
Lines which are too long will be truncated and displayed on the next
line while also taking into account any colored output. This works with any
number of columns.
This removes the need for the module to play games with encoding newlines
and tabs to make the output look nice.
As a start, this functionality was added to the command display.
This fixes a crash associated with toggling the iftype to AP mode
then calling GetDiagnostics. The diagnostic interface is never
cleaned up when netdev goes down so DBus calls can still be made
which ends up crashing since the AP interface objects are no longer
valid.
Running the following iwctl commands in a script (once or twice)
triggers this crash reliably:
iwctl device wlp2s0 set-property Mode ap
iwctl device wlp2s0 set-property Mode station
iwctl device wlp2s0 set-property Mode ap
iwctl ap wlp2s0 start myssid secret123
iwctl ap wlp2s0 show

The generic proxy property display was limited to a width for names/value
which makes the output look nice and uniform, but will cut off any values
which are longer than this limit.
This patch adds some logic to detect this, and continue displaying the
value on the next line.
The width arguments were also updated to be unsigned, which allows checking
the length without a cast.
testAgent had a few tests which weren't reliable, and one was not
actually testing anything, or at least not what the name implied it
should be testing.
The first issue was using iwctl in the first place. There is not a
reliable way to know when iwctl has registered its agent so relying on
that with a sleep, or waiting for the service to become available isn't
100% fool proof. To fix this use the updated PSKAgent which allows
multiple to be registered. This ensures the agent is ready for requests.
This test was also renamed to be consistent with what its actually
testing: that IWD uses the first agent registered.
This removes test_connection_with_other_agent as well because this test
case is covered by the client test itself. There is no need to re-test
iwctl's agent functionality here.
By creating a new bus connection for each agent we can register multiple
with IWD. This did mean the agent interface needs to be unique for each
agent (removing _agent_manager_if) as well as tracking multiple agents
in a list.
IWD uses a few pragmas to ignore warnings which clang does
not support. For -Werror builds these cause build failures
but can be fixed by ignoring unknown warnings and pragmas.
The dbus proxy code assumes that every interface has a set of
properties registered in a 'proxy_interface_property' structure,
assuming the interface has any properties at all. If the interface
is assumed to have no properties (and no property table) but
actually does, the property table lookup fails but is assumed to
have succeeded and causes a crash.
This caused iwctl to crash after some properties were added to DPP
since the DPP interface previously had no properties.
Now, check that the property table was valid before accessing it. This
should allow properties to be added to new interfaces without crashing
older versions of iwctl.
About a month ago hostapd was changed to set the secure bit on
eapol frames during rekeys (bc36991791). The spec is ambiguous
about this and has conflicting info depending on the sections you
read (12.7.2 vs 12.7.6). According to the hostapd commit log TGme
is trying to clarify this and wants to set secure=1 in the case
of rekeys. Because of this, IWD is completely broken with rekeys
since its disallows secure=1 on PTK 1/4 and 2/4.
Now, a bool is passed to the verify functions which signifies if
the PTK has been negotiated already. If secure differs from this
the key frame is not verified.
The test here is verifying that a DBus Connect() call will still
work with 'other' agents registered. In this case it uses iwctl to
set a password, then call Connect() manually.
The problem here is that we have no way of knowing when iwctl fully
starts and registers its agent. There was a sleep in there but that
is unreliable and we occationally were still getting past that without
iwctl having started fully.
To fix this properly we need to wait for iwctl's agent service to appear
on the bus. Since the bus name is unknown we must first find all names,
then cross reference their PID's against the iwctl PID. This is done
using ListNames, and GetConnectionUnixProcessID APIs.
The rekey/reauth logic was broken in a few different ways.
For rekeys the event list was not being reset so any past 4-way
handshake would allow the call to pass. This actually removes
the need for the sleep in the extended key ID test because the
actual handshake event is waited for correctly.
For both rekeys and reauths, just waiting for the EAP/handshake
events was not enough. Without checking if the client got
disconnected we essentially allow a full disconnect and reconnect,
meaning the rekey/reauth failed.
Now a 'disallow' array can be passed to wait_for_event which will
throw an exception if any events in that array are encountered
while waiting for the target event.
Yet another weird UML quirk. The intent of this tests was to ensure
the profile gets encrypted, and to check this both the mtime and
contents of the profile were checked.
But under UML the profile is copied, IWD started, and the profile
is encrypted all without any time passing. The (same) mtime was
then updated without any changes which fails the mtime check.
This puts a sleep after copying the profile to ensure the system
time differs once IWD encrypts the profile.
In UML if any process dies while test-runner is waiting for the DBus
service or some socket to be available it will block forever. This
is due to the way the non_block_wait works.
Its not optimal but it essentially polls over some input function
until the conditions are met. And, depending on the input function,
this can cause UML to hang since it never has a chance to go idle
and advance the time clock.
This can be fixed, at least for services/sockets, by sleeping in
the input function allowing time to pass. This will then allow
test-runner to bail out with an exception.
This patch adds a new wait_for_service function which handles this
automatically, and wait_for_socket was refactored to behave
similarly.
This function was checking if the process object exists, which can
persist long after a process is killed, or dies unexpectedly. Check
that the actual PID exists by sending signal 0.
The man pages (iwd.network) have a section about how to name provisioning
files containing non-alphanumeric characters but not everyone reads the
entire man page.
Warning them that the provisioning file was not read and pointing to
'man iwd.network' should lead someone in the right direction.
EAP-Success might come in with an identifier that is incremented by 1
from the last Response packet. Since identifier field is a byte, the
value might overflow (from 255 -> 0.) This overflow isn't handled
properly resulting in EAP-Success/Failure packets with a 0 identifier
due to overflow being erroneously ignored. Fix that.
