EAP-PWD was hard coded to only work on LE architectures. This
adds 2 conversion functions to go from network byte order (BE)
to any native architecture, and vise versa.
The file, src/ecc.c was taken from the bluez project:
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/src/shared/ecc.c
There were minor changes made, e.g. changing some functions to globals
for access in EAP-PWD as well as removing some unneeded code. There was
also some code appended which allows for point addition, modulus inverse
as well as a function to compute a Y value given an X.
If Control Port over NL80211 is not supported, open up a PAE socket and
stuff it into an l_io on the netdev object. Install a read handler on
the l_io and call __eapol_rx_packet as needed.
With the introduction of Control Port Over NL80211 feature, the
transport details need to be moved out of eapol and into netdev.c.
Whether a given WiFi hardware supports transfer of Control Port packets
over NL80211 is Wiphy and kernel version related, so the transport
decisions need to be made elsewhere.
If the hw.conf option 'start_iwd' is false, then iwd is started
inside the python test, which means it will not know if the
--valgrind option was passed to test runner. If this is the case
an environment variable is set so the python test knows the
option is being used.
Update the expected DBus exception in the manual connect case, affected
by recent EAP changes. Also slightly improve the comment in the file
although it's still not 100% correct.
This also tests multiple agent requests for one network connection
because the TTLS client private key is not in the config file and the
MSCHAPV2 password is not in the config file.
Make 3 connections in test EAP-TLS, one with an unencrypted private key,
one with the private key passphrase provided in the provisioning file
and one with the passphrase provided through the agent. Also improve
the scanning logic at the beginning.
On connect add any secrets we've received through the agent to the
l_settings objects which the EAP methods will process in load_settings.
The settings object is modified but is never written to storage. If
this was to change because some settings need to be saved to storage,
a new l_settings object might be needed with the union of the settings
from the file and the secrets so as to avoid saving the sensitive data.
These EAP methods do not store the identity inside the settings file
since it is obtained from the SIM card, then provided to IWD via
get_identity method. If the get_identity method is implemented, do
not fail the settings check when EAP-Identity is missing.
Allow passing a list of passphrases for subsequent agent requests to the
PSKAgent constructor. This also makes existing tests stricter because
a spurious agent request will not receive the same passphrase.
Use eap_check_settings directly from network.c before we start the
connection attempt at netdev.c level, to obtain all of the required
passwords/passphrases through the agent. This is in network.c because
here we can decide the policies for whether to call the agent in
autoconnect or only if we had a request from the user, also whether we
want to save any of that for later re-use (either password data or
kernel-side key serial), etc.
In this patch we save the credentials for the lifetime of the network
object in memory, and we skip the network if it requires any passphrases
we don't have while in autoconnect, same as with PSK networks where the
PSK isn't given in the settings. Note that NetworkManager does pop up
the password window for PSK or EAP passwords even in autoconnect.
If EAP needs multiple passwords we will call the agent sequentially for
each.
Confirm that the PEM file paths that we'll be passing to the l_tls
object are loading Ok and request/validate the private key passphrase
if needed. Then also call eap_check_settings to validate the inner
method's settings.
