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.
This cleans up the internal interface between different modules and is
the first step in getting wpa_supplicant design closer to hostapd as far
as WPS is concerned.
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 depends on a patch to Linux nl80211/mac80211 that has not yet been
merged into wireless-testing. If that change is not present, the old
mechanism (WEXT) will be used instead.
It is better to pass both HT Capabilities and HT Operation IEs in the
same function call since it may be easier for the driver wrappers to
handle the changes without having to wait for the other IE in the
wrapper code.
If country_code is set in hostapd.conf, hostapd will now update nl80211
regulatory data by setting the alpha2 string for CRDA. In other words,
"iw reg set <alpha2>" is not needed anymore when using hostapd.
The patch for 0.9.9 was merged into the upstream OpenSSL 0.9.9 tree and
is not needed for EAP-FAST support with that OpenSSL version. The patch
for 0.9.8i is now using the same API that was included in 0.9.9.
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.
Changed accounting_sta_start() to call accounting_sta_get_id()
internally in accounting.c so that external callers do not need to do
anything to allocate unique accounting id. When starting a new session,
a unique identifier is needed anyway, so no need to keep these
operations separate.
