hostapd will now go through the RIC Request and process each RDIE. Only
WMM TSPEC requests are currently supported; all other request
descriptors will be declined.
RIC Response is written by hostapd and verified by wpa_supplicant (MIC
validation). wpa_supplicant does not yet have code to notify the driver
about the resource request results.
This adds first part of FT resource request as part of Reassocition
Request frame (i.e., FT Protocol, not FT Resource Request Protocol).
wpa_supplicant can generate a test resource request when driver_test.c
is used with internal MLME code and hostapd can verify the FTIE MIC
properly with the included RIC Request.
The actual RIC Request IEs are not processed yet and hostapd does not
yet reply with RIC Response (nor would wpa_supplicant be able to
validate the FTIE MIC for a frame with RIC Response).
Calculate the estimated medium time using integer variables since there
is no real need to use floating point arithmetics here. In addition,
make sure there is no division by zero regardless of how invalid the
request from the station is. Reject invalid parameters and refuse
requests that would take most of the bandwidth by themselves.
Add test code into wpa_supplicant mlme.c to allow WMM-AC negotiation to
be tested with driver_test.
This updates the terminogy to match with the final WMM specification. In
addition, some of the WMM TSPEC structure fields were in incorrect order
and used without byte order swapping. Those are also taken care of this
cleanup patch.
Previously, both CONFIG_IEEE80211W=y and CONFIG_IEEE80211R=y were needed
to enable SHA256-based key handshake (WPA-PSK-SHA256 and
WPA-EAP-SHA256). This can now be done with just CONFIG_IEEE80211W=y.
If the bind() on /tmp/wpa_ctrl_<pid>_<in-proc-counter> fails with
EADDRINUSE, there is an existing socket file with the name we are trying
to create. Since getpid() is unique, there cannot be another process
using that socket and we can just unlink the file and try again. This
can speed up client connection if wpa_cli is killed without allowing it
to clean up the socket file. [Bug 288]
If a Registrar tries to configure the AP, but fails to validate the
device password (AP PIN), lock the AP setup after four failures. This
protects the AP PIN against brute force guessing attacks.
Some WPS APs do not set Selected Registrar attribute to 1 properly when
using an external Registrar. Allow such an AP to be selected for PIN
registration after couple of scan runs that do not find APs marked with
Selected Registrar = 1. This allows wpa_supplicant to iterate through
all APs that advertise WPS support without delaying connection with
implementations that set Selected Registrar = 1 properly.
This operation can now be moved into an external program by configuring
hostapd with wps_cred_processing=1 and skip_cred_build=1. A new
ctrl_iface message (WPS-REG-SUCCESS <Enrollee MAC addr> <UUID-E>) will
be used to notify external programs of each successful registration and
that can be used as a tricker to move from unconfigured to configured
state.
The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.
IEEE 802.11w/D7.0 incorrectly changed the Action Category from 8 to 7
when renaming Ping to SA Query. Category 7 is reserved for HT (IEEE
802.11n) and IEEE 802.11w will need to continue to use the category 8
that was allocated for it.
This commit changes just the name and Action category per D7.0. The
retransmit/timeout processing in the AP is not yet updated with the
changes in D7.0.
This callback is now used to stop wpa_supplicant from trying to continue
using parameters (most likely, device password) that do not work in a
loop. In addition, wpa_gui can now notify user of failed registration.
The event callback will be used for various event messages and the M2D
notification is the first such message. It is used to notify wpa_gui
about Registrar not yet knowing the device password (PIN).
Whenever new scan results include WPS AP(s) and the client is not
associated, send a notification message to control interface monitors.
This makes it easier for GUIs to notify the user about possible WPS
availability without having to go through the scan results.
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 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.
IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.
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.
This adds most of the new frame format and identifier definitions from IEEE
802.11w/D6.0. In addition, the RSN IE capability field values for MFP is
replaced with the new two-bit version with MFPC (capable) and MFPR
(required) processing.
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).

Added configuration of MFP related parameters with WEXT. The changes to
linux/wireless.h have not yet been applied to the Linux kernel tree, so the
code using them is still open to changes and is ifdef'ed out if
CONFIG_IEEE80211W is not set.
Add the new flags which are supposed to be included in Linux 2.6.27
for the drivers which want to do 4-way handshake and to know PMK.

struct wpa_ie_hdr had separate fields for 24-bit OUI and 8-bit oui_type
for WPA/RSN selectors. {WPA,RSN}_SELECTOR_{GET,PUT} access these four
octets through oui and the "out-of-bounds" access for the fourth octet is
actually reading/writing oui_type. This works fine, but some tools complain
about the array bounds "failure". Since oui_type is never accessed
separately, the simplest fix is to just combine these into a single 4-octet
field.
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.
