Most users of storage_network_open don't log errors when the function
returns a NULL and fall back to defaults (empty l_settings).
storage_network_open() itself only logs errors if the flie is encrypted.
Now also log an error when l_settings_load_from_file() fails to help track
down potential syntax errors.
Drop the wrong negation in the error check. Check that there are no extra
characters after prefix length suffix. Reset errno 0 before the strtoul
call, as recommended by the manpage.
This is actually a false positive only because
p2p_device_validate_conn_wfd bails out if the IE is NULL which
avoids using wfd_data_length. But its subtle and without inspecting
the code it does seem like the length could be used uninitialized.

Though the documentation for NLMSG_OK uses an int type for the length
the actual check is based on nlmsghdr->nlmsg_len which is a 32 bit
unsigned integer. Clang was complaining about one call in nlmon.c
because nlmsg_len was int type. Every other usage in nlmon.c uses
a uint32_t, so use that both for consistency and to fix the warning.

On musl-gcc the compiler is giving a warning for igtk_key_index
and gtk_key_index being used uninitialized. This isn't possible
since they are only used if gtk/igtk are non-NULL so pragma to
ignore the warning.

Since commit 922fa099721903b106a7bc1ccd1ffe8c4a7bce69 in hostap, our
setting of config_methods on P2P-client interface was ignored. Work
around that commit, in addition to the previous workaround we have in
this test, to again ensure the correct config_methods value is used.
This was lazily copied from UML but really made no sense in the context
of QEMU. First QEMU needs the virtfs option to define the mount tag and
in addition a 9p mount should be used rather than 'hostfs'.
The glob match was completely broken for --verbose because globs
are actually path matches, not generally for strings. Instead
match based on regular expressions.
First the verbose option was fixed to store it as an array as well
as write any list arguments into the kernel command line properly
(str() would include []). This has worked up until now because the
'in' keyword in python will work on strings just as well
as lists, for example:
>>> 'test' in 'this,is,a,test'
True
Then, the glob match was replaced with a regex match. Any exceptions
are caught and somewhat ignored (printed, but only seen with --debug).
This only guards against fatal exceptions from a user passing an
invalid expression.
For network configuration files the man pages (iwd.network) state
that [General].{AlwaysRandomizeAddress,AddressOverride} are only
used if main.conf has [General].AddressRandomization=network.
This actually was not being enforced and both iwd.network settings
were still taken into account regardless of what AddressRandomization
was set to (even disabled).
The handshake setup code now checks the AddressRandomization value
and if anything other than 'network' skips the randomization.
This bit of code was throwing exceptions if a test cleaned up files that
test-runner was expecting to clean up. Specifically testHotspot swaps out
main.conf and PSK files many times. This led to the exception being thrown,
caught, and ignored but further on test-runner would print:
"File _X_ not cleaned up!"
Now the files will be checked if they exist before trying to remove it.
There were a few places in dpp/dpp-util which passed a single byte but
was being read in with va_arg(va, size_t). On some architectures this was
causing failures presumably from the compiler using an integer type
smaller than size_t. As we do elsewhere, cast to size_t to force the
compiler to pass a properly sized iteger to va_arg.
Similarly to ofono/phonesim allow tests to be skipped if wpa_supplicant
is not found on the system.
This required some changes to DPP/P2P where Wpas() should be called first
since this can now throw a SkipTest exception.
The Wpas class was also made to allow __del__ to be called without
throwing additional exceptions in case wpa_supplicant was not found.
This allows the EAP tests to pass, but the fix really needs to be in
hostapd itself. Hostapd currently tries to lookup the EAP session
immediately after receiving EAPOL_REAUTH. This uses the identity
it has stored which, in the case of PEAP/TTLS, will always be a phase2
identity. During this initial lookup hostapd hard codes the identity
to be phase1 which is not true for PEAP/TTLS, and the lookup fails.
The current way this was being done was to import collections and
use collections.Mapping. This has been deprecated since python 3.3
but has worked up until python 3.10. After python 3.10 this will
no longer work, and Mapping must be imported from collections.abc.
This was passing IFNAME= along with EAPOL_REAUTH which does not work
in the context of a hostapd socket where the iface is already implied.
This fixes that issue as well as resets the events array and actually
waits for the required events afterwards.
After one of the eap-tls-common-based methods succeeds keep the TLS
tunnel instance until the method is freed, rather than free it the
moment the method succeeds. This fixes repeated method runs where until
now each next run would attempt to create a new TLS tunnel instance
but would have no authentication data (CA certificate, client
certificate, private key and private key passphrase) since those are
were by the old l_tls object from the moment of the l_tls_set_auth_data()
call.
Use l_tls_reset() to reset the TLS state after method success, followed
by a new l_tls_start() when the reauthentication starts.
The signal agent notifications were changed which breaks this test.
Specifically commit ce227e7b94 sends a notification when connected
which breaks the 'agent.calls' check. Since this check is done both
after connecting and once already connected the initial value may
be 1 or 0. Because of this that check was removed entirely.
This test was just piping the PSK files into /tmp/iwd/ssidCCMP.psk
which is a bit fragile if the storage dir was ever to change. Instead
use copy_to_storage and the 'name' keyword to copy the file.
If the user specifies the same parent directory for several outfiles
skip mounting since it already exists. For example:
--monitor /outfiles/monitor.txt --result /outfiles/result.txt
Inside the virtual environments /tmp is mounted as its own FS and not
taken from the host. This poses issues if any output files are directly
under /tmp since test-runner tries to mount the parent directory (/tmp).
The can be fixed by ensuring these output files are either not under
/tmp or at least one folder down the tree (e.g. /tmp/outputs/outfile.txt).
Now this requirement is enforced and test-runner will not start if any
output files parent directory is /tmp.
Usually the test home directory is a git repo somewhere e.g. under
/home. But if the home directory is located under /tmp this poses
a problem since UML remounts /tmp. To handle both cases mount
the home directory explicity.
Certain aspects of QEMU like mounting host directories may still require
root access but for UML this is not the case. To handle both cases first
check if SUDO_UID/GID are set and use those to obtain the actual users
ID's. Otherwise if running as non-root use the UID/GID of the user
directly.
A user reported that IWD was failing to FT in some cases and this was
due to the AP setting the Retry bit in the frame type. This was
unexpected by IWD since it directly checks the frame type against
0x00b0 which does not account for any B8-B15 bits being set.
IWD doesn't need to verify the frame type field for a few reasons:
First mpdu_validate checks the management frame type, Second the kernel
checks prior to forwarding the event. Because of this the check was
removed completely.

station_signal_agent_notify() has been refactored so that its usage is
simpler. station_rssi_level_changed() has been replaced by an inlined
call to station_signal_agent_notify().
The call to netdev_rssi_level_init() in netdev_connect_common() is
currently a no-op, because netdev->connected has not yet been set at
this stage of the connection attempt. Because netdev_rssi_level_init()
is only used twice, it's been replaced by two inlined calls to
netdev_set_rssi_level_idx().
The SignalLevelAgent API is currently broken by the system bus's
security policy, which blocks iwd's outgoing method call messages. This
patch punches a hole for method calls on the
net.connman.iwd.SignalLevelAgent interface.
There may be situations where DNS information should not be set (for
example in auto-tests where the resolver daemon is not running) or if a
user wishes to ignore DNS information obtained.
Allows granularly specifying the DHCP logging level. This allows the
user to tailor the output to what they need. By default, always display
info, errors and warnings to match the rest of iwd.
Setting `IWD_DHCP_DEBUG` to "debug", "info", "warn", "error" will limit
the logging to that level or higher allowing the default logging
verbosity to be reduced.
Setting `IWD_DHCP_DEBUG` to "1" as per the current behavior will
continue to enable debug level logging.
Use scapy library which allows one to easily construct and fudge various
network packets. This makes constructing spoofed packets much easier
and more readable compared to hex-encoded, hand-crafted frames.
The TA/BSSID addresses of spoofed disassociate frames were set
incorrectly. They should be using the 02:00:00:XX:XX:XX address, but
instead were being converted over to 42:00:00:XX:XX:XX address
