This mode allows associated stations to use 4-address frames to allow
layer 2 bridging to be used. At least for the time being, this is only
supported with driver=nl80211.
This adds config_methods configuration option for wpa_supplicant
following the design used in hostapd. In addition, the string is
now parsed in common code from src/wps/wps_common.c and the list
of configurable methods include all the defined methods from
WPS 1.0h spec.
The use_psk_key parameter can now be used to force the Registrar to
use PSK format instead of ASCII passphrase when building a Credential
for the Enrollee. For now, this is not enabled, but it could be enabled
either based on external (to WPS) configuration or automatically set
based on some WPS attribute values from the Enrollee.
Instead of dropping the configured PSK and deriving it based on
passphrase, use the provided PSK as-is and also maintain a copy of
the passphrase since it can be of use later. This allows both values
to be configured without havign to derive the PSK every time the
network is initialized.
WPA_TRACE=y builds will now verify that memory allocation in done
consistently using os_{zalloc,malloc,realloc,strdup,free} (i.e., no
mixing of os_* functions and unwrapper functions). In addition, some
common memory allocation issues (double-free, memory leaks, etc.) are
detected automatically.
WPA_TRACE=y can now be used to enable internal backtrace support that
will provide more details about implementation errors, e.g., when some
resources are not released correctly. In addition, this will print out
a backtrace automatically if SIGSEGV is received.
Replace driver wrapper calls to hostapd_tx_status(),
hostapd_rx_from_unknown_sta(), hostapd_mgmt_rx(), and
hostapd_mgmt_tx_cb() with new generic driver events
EVENT_TX_STATUS, EVENT_RX_FROM_UNKNOWN, and EVENT_RX_MGMT.
This cleans up lot of the driver wrapper code to be less dependent
on whether it is being used within wpa_supplicant AP mode or hostapd.
This remove the need from driver_test.c to go through internal hostapd
structures to find the appropriate BSS when reporting events on secondary
BSSes.
The separate header file is not needed since none of the driver wrappers
include it anymore. Move the WLAN_STA_* definitions back to be together
with struct sta_info definition.
This removes need for including hostapd/sta_flags.h into driver
wrappers and removes any remaining dependencies between driver flags
and internal hostapd flags.
The WMM STA flag is already taken care of by handle_assoc_cb() and there
is no point trying to do this unless hostapd is taking care MLME
processing, so no need to call this from drv_callbacks.c.
The Prism54.org project seems have been dead for a while and it does not
look like this driver would ever be maintained again. Furthermore, it is
difficult to find a version that would work with the driver_prism54.c
wrapper and there is another driver for these card in the Linux kernel
tree.
The hostapd integration in driver_prism54.c is quite different from the
other driver wrappers and would require major effort to get it cleaned
up. Since there does not seem to be any real users for the cleaned up
version, there does not seem to be justification to spend this effort on
the wrapper. This old code is making it much more difficult to clean up
the driver interface and at this point, the best option seems to be to
remove the driver wrappers. Should someone really still need this, the
old code will continue to be available in hostapd 0.6.x.
Instead of using the latest selected registrar change, collect selected
registrar information separately from all registrars and use the union
of this information when building the WPS IE for Beacon and Probe
Response frames.
Note: SetSelectedRegistrar UPnP action does not include a unique
identifier, so the ER matching routine is based only on the IP address
of the ER. In theory, there could be multiple ERs using the same IP
address (but different port or URL), so there may be some corner cases
that would not always match the correct ER entry at the AP. Anyway, this
is not really expected to occur in normal use cases and even if it did
happen, the selected registrar information is not any worse than it was
before when only the last change from any registrar for being
advertized.
These callbacks can be handled internally within core WPS code, so there
is no need to go through wps_hostapd.c with a callback function that is
just calling back into the core WPS code.

IEEE 802.11w uses distinct key indexes (4 and 5) so the same
get_seqnum() handler can be used to fetch packet number for both
TKIP/CCMP and BIP(using IGTK).
Since the new get_seqnum_igtk() handler was not actually implemented by
any driver wrapper, this may also fix BIP/IGTK sequence number reporting
with driver_nl80211.c.
There was code for configuring this, but no driver wrapper actually
implements the actual setting. Remove this for now to reduce potential
confusion and to simply the driver interface.
In addition to the bitrate, the only other variable in this structure
is used internally in hostapd. Move this structure into hostapd.h and
make the driver API use simpler data structure (array of bitrates).
if_add/if_remove can now be used as the generic driver ops for adding
and removing virtual interfaces of various types. In addition,
driver_nl80211.c is now including this code unconditionally, so that
the functions are not limited only for hostapd.
