If a STA reassociates and changes key_mgmt (e.g., from WPA-PSK to WPS),
hostapd needs to reset some of the existing STA and WPA state machine
variables to allow correct processing for the new association.
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).
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.
This was used to allow hostapd to associate as a non-AP STA to another
AP one the same channel while still acting as an AP with the Host AP
driver. This was very experimental and did not work with all firmware
versions. Nowadays, much better way of doing this is to use mac80211
virtual non-AP STA interface. As such, this experimental code can be
removed from hostapd to reduce the code size and make MLME code easier
to understand since it is now only handling AP functionality.
This code was not finished and did not work with the current mac80211
design. In order to avoid confusing users, it is better to remove this
completely for now and look at new implementation to work with mac80211.
Move the use of 802.11 header protocol field into driver_hostap.c since
this is a Host AP driver specific mechanism and other driver wrappers
should not really need to know about it.
This updates management frame protection to use the assocition ping process
from the latest draft (D6.0) to protect against unauthenticated
authenticate or (re)associate frames dropping association.
The configuration data should only store the static configuration data and
not dynamic data. In addition, storing HT configuration and state in IEs is
not the easiest way of doing this, so use more convenient data types for
storing configuration and dynamic state. The HT IEs are then generated
based on the static configuration and dynamic state whenever needed.
This commit brings in cleaned up version of IEEE 802.11n implementation
from Intel (1). The Intel tarball includes number of other changes, too,
and only the changes specific to IEEE 802.11n are brought in here. In
addition, this does not include all the changes (e.g., some of the
configuration parameters are still missing and driver wrapper changes for
mac80211 were not included).

This allows associations to be denied if the STA tries to use too large
listen interval. The default value is 65535 which matches with the field
size limits.
