This adds support for setting of a regulatory domain to wpa_supplicant
drivers. It also adds regulatory domain setting for the nl80211 driver.
We expect an ISO / IEC 3166 alpha2 in the wpa configuration file as a
global.
Since only one KDF is currently supported, the negotiation is not
allowed and peer must be rejected if it tries to send KDF selection in a
Challenge message. The negotiation code is left in the file and just
commented out since it was tested to work and can be used in the future
if another KDF is added.
The attribute uses 'Actual Identity Length' field to indicate the exact
(pre-padding) length of the Identity. This actual length should be used
as the length, not the remaining attribute length.
This was previously worked around by stripping null termination away
from the end of the identity string at EAP-SIM and EAP-AKA server code.
However, it is likely that that workaround is not really needed and the
real problem was in AT_IDENTITY parsing. Anyway, the workaround is left
in just in case it was really needed with some implementations.
This IE is not (at least yet) actually used for anything, but parsing it
cleans up verbose debug log a bit since thie previously unknown, but
commonly used, vendor IE was being reported as unknown.
This allows the same source code file to be shared for both methods. For
now, this is only in eap_aka_prime.c, but eventually, changes in
eap_aka_prime.c are likely to be merged into eap_aka.c at which point
the separate eap_aka_prime.c can be removed.
This is just making an as-is copy of EAP-AKA server and peer
implementation into a new file and by using the different EAP method
type that is allocated for EAP-AKA' (50). None of the other differences
between EAP-AKA and EAP-AKA' are not yet included.
It is likely that once EAP-AKA' implementation is done and is found to
work correctly, large part of the EAP-AKA and EAP-AKA' code will be
shared. However, it is not reasonable to destabilize EAP-AKA
implementation at this point before it is clearer what the final
differences will be.
Since the Registrar may not yet know the UUID-E when a new PIN is
entered, use of a wildcard PIN that works with any UUID-E can be useful.
Such a PIN will be bound to the first Enrollee trying to use it and it
will be invalidated after the first use.
Fragment WPS IE if needed to fit into the IE length limits in hostapd
and Reassemble WPS IE data from multiple IEs in wpa_supplicant.
In addition, moved WPS code from events.c into wps_supplicant.c to clean
up module interfaces.
These functions fit in better with the category of functions included in
wps.c. wps_common.c is now used for generic helper functions (currently,
only crypto code).
WPS IE is now passed from hostapd association processing into EAP-WSC
and WPS processing. Request Type attribute is parsed from this
information and if the request is for a WLAN Manager Registrar,
additional management keys are derived (to be used with UPnP).
The wps_context data is now managed at wpa_supplicant, not EAP-WSC. This
makes wpa_supplicant design for WPS match with hostapd one and also
makes it easier configure whatever parameters and callbacks are needed
for WPS.
Previously, wpa_supplicant as Enrollee case was handled using a
different callback function pointer. However, now that the wps_context
structure is allocated for all cases, the same variable can be used in
all cases.
Previously, hardcoded values were used in wps_enrollee.c. These are now
moved into shared data in struct wps_context. In case of
AP/Authenticator, these are initialized in wps_hostapd.c. In case of
client/supplicant, these are now initialized in EAP-WSC peer method,
but will probably end up being moved into higher layer for better
configuration.
EAP-WSC peer method for
This allows the network to be used after the Registrar configuration
step. The local WPS network is replaced with a new network block
similarly to the case of acting as an Enrollee.
This makes it easier to store old AP settings into wps->cred (and allow
them to modified and taken into use in the future). Separation between
Credential and AP Settings building is also cleaner in this design.
The old (i.e., currently used) AP Settings are processed. For now, they
are copied as-is into M8 as new AP Settings to avoid changing
configuration. This should be changed to allow external programs (e.g.,
GUI) to fetch the old AP settings over ctrl_iface and then allow
settings to be changed before sending M8 with the new settings.
The core processing of attributes into struct wps_credential is now in
wps_common.c (was in wps_enrollee.c), so that the same code can be
shared with Registrar.
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.
Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.
