Instead of using 0x00 as the extra character, use space (' ') to
avoid failing tests that verify that the variable length string
attributes are not null terminated. In addition, this workaround
can now be disabled by defining CONFIG_WPS_STRICT for the build.
This can be done by adding following line to .config:
CFLAGS += -DCONFIG_WPS_STRICT
However, it should be noted that such a build may not interoperate
with some deployed WPS 1.0 -based implementations and as such, is
mainly designed for testing.
Use shared functions for converting Primary Device Type between binary
and string formats. In addition, use array of eight octets instead of a
specific structure with multiple fields to reduce code complexity.
Some deployed WPS implementations fail to parse zero-length attributes.
As a workaround, send a null character if the device attribute string is
empty. This allows default values (empty strings) to be used without
interop issues.
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 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.
