test-eapol was passing zero as the MTU, so this simply needed to be
updated to remove that parameter.
test-wsc was actually setting a MTU value so when building the
settings we now add the proper value so the MTU can be set with
__eap_set_config.
This was refactored to set the mtu via __eap_set_config rather than
passing the MTU into eap_init. This makes eap work in a similar fashion
as eapol (i.e. __eapol_set_config).
If __eap_set_config is not used, the MTU will be set to 1020, which is
the same as previously passing 0 to eap_init.
Since iwd_modules_init is now defered until nl80211_appeared, we can
assume the nl80211 object is available. This removes the need for
netdev_set_nl80211 completely.
In preparation for integrating IWD_MODULE into modules which require
nl80211 we move the module init into the nl80211_appeared callback.
This will guarentee that the nl80211 is available during module init
and allow modules to get their own copy of nl80211 rather than needing
a set function (e.g. netdev_set_nl80211).
Since the dbus name request callback happens before this as well any
dbus module can also use IWD_MODULE and simply assume the dbus object
is ready.
plugin_init was also deferred to nl80211_appeared since some plugins
depend on modules being initialized.
Converts agent into an IWD module. This removes the dbus dependency
on agent. Since dbus is initialized very early we can assume
dbus_get_bus is going to return a valid object.
Previously, station state 'connected' used to identify an interface associated
with AP. With the introduction of netconfig, an interface is assumed to be
connected after the IP addresses have been assigned to it. If netconfig is
disabled, the behavior remains unchanged.
The -U parameter only allowed for a list of unit tests to be run.
Most of the time for sanity checking you want to run all the unit
tests so this has been changed to take an optional argument.
Now, the -U flag (by itself) will run all unit tests. Running a
single or list of unit tests can still be achieved by:
--unit-tests=test-eapol,test-crypto
Refactored eapol_sm_test_tls to take a l_settings object rather than
a settings string. This lets the caller either load from data or
from file (the new test loads the build time generated tls-settings
file).
To test embedded certs we need a settings file containing the same
PEMs that we generate during build time. In the same fashion generate
tls-settings.8021x file using the previously generated PEMs.
Refactoring was required to allow for embedded certs. The existing
eap_tls_state object was changed to hold the cert types (l_queue,
l_certchain, l_key) rather than the file path, since there may not
actually be separate PEM files.
Care was taken to properly manage the memory of these objects.
Since the TLS object takes ownership when setting auth data or the
CA certs all error cases must be handled properly to free these
objects after they are loaded and in addition they must be set to
NULL so that the cleanup doesn't double free them.
If everything goes to plan, we load all the PEMs in settings_load,
provide these objects to the TLS APIs, and then NULL out the
pointers (TLS now owns this memory). If anything fails between
settings_load and l_tls_start we must free these objects.
A special format must be used to indicate that a PEM is embedded
inside the settings file. First, the l_settings format should be
followed for the PEM itself, e.g.
[@pem@my_ca_cert]
<CA Cert data>
This PEM can then be referenced by "embed:my_ca_cert", e.g.
EAP-TLS-CACert=embed:my_ca_cert
Any other value not starting with "embed:" will be treated as a file
path.
