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.
It was found that some distros do not ship with a regulatory.db file.
This is required to run some of the autotests, and if not found on the
system the kernel build will fail due to some of the IWD config
options which require regulatory.db.
The fix is to manually download regulatory.db from git.kernel.org and
place it in /lib/firmware.
The IPv6 default route needs to be explicitly revoked. Unlike in IPv4,
there is no SRC address associated with the route and it will not be
removed on address removal.
The network configuration options for IPv6 are grouped under [IPv6]
and include the following:
ip= ADDRESS/PREFIX
gateway=ADDRESS
dns=ADDRESS
The placeholders for DHCPv6 are placed along the way and marked
as TODO items.
Previously, netconfig_ipv4_select_and_install was used to install
addresses on initial connection to a network and after we have roamed.
Now for the after roaming connection scenario we have
netconfig_reconfigure. Remove roaming related code from
netconfig_ipv4_select_and_install
As part of the de-coupling from station object, switch all of
the network settings inquiries to use active_settings. active_settings
are set with netconfig_configure by the owner of netconfig object
and removed with netconfig_reset once network disconnects.
Instead of relying on station state changed signal, netconfig
introduces three new API calls to configure, re-configure and
reset the network configurations. The owner of netconfig object
is responsible for initiating the re-configuration of the device
depending on its state.
As a first step to enable the usage of netconfig in ead and
prospective transition to be a part of ell, the public API for
creation and destruction of the netconfig objects has been
renamed and changed. Instead of hiding the netconfig objects inside
of netconfig module, the object is now passed back to the caller.
The internal queue of netconfig objects remains untouched, due
to limitations in ell’s implementation of rtnl. After the proper
changes are done to ell, netconfig_list is expected to be removed
from netconfig module.
