This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.
This commit does not included changes to WPS or P2P to allow GCMP to be

It should be noted that the maximum length of the response buffer is

This function can be used to clean up local UNIX domain socket files
that may be left over from clients that were previously connected to
wpa_supplicant. At least for now, this is only available for Android
builds.
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.
"hostapd_cli ess_disassoc (STA addr) (URL)" can now be used to send
an ESS Dissassociation Imminent notification to the STA. This event
is shown in wpa_supplicant ctrl_iface monitors (e.g., wpa_cli):
"WNM: ESS Disassociation Imminent - session_info_url=http://example.com/session/"
The new wpa_supplicant.conf file global parameters interworking and
hessid can be used to configure wpa_supplicant to include
Interworking element in Probe Request frames.
GAS/ANQP is a generic protocol and in no way specific to P2P, so move
routines used to build GAS/ANQP frames to a separate file that can be
shared for other uses than just P2P service discovery.
These can be used in some cases with a bitfield having multiple
AKMs enabled (e.g., WPA-PSK and WPA-PSK-SHA256). Address those
cases by checking whether any of the matching AKM are included.
CFLAGS += -DCONFIG_RSN_TESTING in .config and rsn_testing=1 in
hostapd.conf can now be used to enable a testing mode that adds
extensions to RSN element. This can be used to check whether
station implementations are incompatible with future extensions
to the RSN element.
Build options can now be used to replace the location of client
sockets for UNIX domain socket control interface:
CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_DIR=\"/tmp\"
CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_PREFIX=\"wpa_ctrl_\"
tdls_prohibit=1 and tdls_prohibit_chan_switch=1 and now be used to
disable use of TDLS or TDLS channel switching in the BSS using
extended cabilities IE as defined in IEEE 802.11z.
CONFIG_WPS_REG_DISABLE_OPEN=y can be used to configure wpa_supplicant
to disable open networks by default when wps_reg command is used to
learn the current AP settings. When this is enabled, there will be a
WPS-OPEN-NETWORK ctrl_iface event and the user will need to explicitly
enable the network (e.g., with "select_network <id>") to connect to
the open network.
The nl80211 driver can report low ACK condition (in fact it reports
complete loss right now only). Use that, along with a config option, to
disconnect stations when the data connection is not working properly,
e.g., due to the STA having went outside the range of the AP. This is
disabled by default and can be enabled with disassoc_low_ack=1 in
hostapd or wpa_supplicant configuration file.

There is no point in maintaining two almost identical versions
of this parser. Move WPA IE parser into wpa_common.c similarly
to what was already the case with RSN IE parse.
Commit d8d940b746 introduced a regression
that prevented TSN APs from being used with WEP since the AP was
rejected if it advertised WPA or RSN IE when we were configured to use
WEP. Resolve this by checking whether the AP is advertising a TSN, i.e.,
whether the AP allows WEP to be used as a group cipher. If so, allow
the AP to be selected if we are configured to use static WEP or
IEEE 802.1X (non-WPA).
It should be noted that this is still somewhat more restricted in AP
selection than earlier wpa_supplicant branches (0.7.x or older) that
ignore the WPA/RSN IE completely when configured for non-WPA.
This tool can be used to capture IEEE 802.11 frames either from a
monitor interface for realtime capturing or from pcap files for
offline analysis. This version is only adding basic infrastructure for
going through the frames and parsing their headers.
A separate build number (etc.) version number postfix can now be
added to the build without having to modify source code files by
defining VERSION_STR_POSTFIX. This can be done, e.g., by adding
following line to .config:
CFLAGS += -DVERSION_STR_POSTFIX=\"-foo\"
If enabled, cross connection allows GO to forward IPv4 packets
using masquerading NAT from the P2P clients in the group to an

interface.
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.
This patch adds support for wired IEEE 802.1X client on the Solaris.
I have tested with these:
OS : OpenSolaris 2009.06
EAP : EAP-MD5
Switch : Cisco Catalyst 2950
A new hostapd_cli command, wps_ap_pin, can now be used to manage
AP PIN at runtime. This can be used to generate a random AP PIN and
to only enable the AP PIN for short period (e.g., based on user
action on the AP device). Use of random AP PIN that is only enabled
for short duration is highly recommended to avoid security issues
with a static AP PIN.
As a compromise between usability and security, do not disable
AP PIN permanently based on failed PIN validations. Instead, go to
AP Setup Locked state for increasing amount of time between each
failure to slow down brute force attacks against the AP PIN.
This avoids problems with some external Registrars that may try
to use the same PIN multiple times without user input. Now, the
user will still be able to fix the PIN and try again later while
a real attack is delayed enough to make it impractical.
Some frequent debug prints are of limited use and make debug output
difficult to read. Make them use a new debug level so that -dd
provides more readable output (-ddd can now be used to enable
the excessive debug prints).
Add a new wpa_supplicant state: interface disabled. This can be used
to allow wpa_supplicant to be running with the network interface even
when the driver does not actually allow any radio operations (e.g.,
due to rfkill).
Allow driver_nl80211.c and driver_wext.c to start while rfkill is in
blocked state (i.e., when ifconfig up fails) and process rfkill
events to block/unblock WLAN.
There are no subdirectories in any of these directories or plans
for adding ones. As such, there is no point in running the loop
that does not do anything and can cause problems with some shells.
IEEE Std 802.11r-2008, 11A.4.2 describes FT initial mobility domain
association in an RSN to include PMKR1Name in the PMKID-List field
in RSN IE in messages 2/4 and 3/4. This makes the RSN IE not be
bitwise identical with the values used in Beacon, Probe Response,
(Re)association Request frames.
The previous versions of wpa_supplicant and hostapd did not add the
PMKR1Name value in EAPOL-Key frame and did not accept it if added
(due to bitwise comparison of RSN IEs). This commit fixes the
implementation to be compliant with the standard by adding the
PMKR1Name value into EAPOL-Key messages during FT 4-Way Handshake and
by verifying that the received value matches with the value derived
locally.
This breaks interoperability with previous wpa_supplicant/hostapd
versions.
This was not supposed to have duplicate value with WPA_AUTH_ALG_LEAP.
The previous version was unable to set FT as the authentication
algorithm with nl80211.
This allows external programs (e.g., UI) to get more information
about server certificate chain used during TLS handshake. This can
be used both to automatically probe the authentication server to
figure out most likely network configuration and to get information
about reasons for failed authentications.
The follow new control interface events are used for this:
CTRL-EVENT-EAP-PEER-CERT
CTRL-EVENT-EAP-TLS-CERT-ERROR
In addition, there is now an option for matching the server certificate
instead of the full certificate chain for cases where a trusted CA is
not configured or even known. This can be used, e.g., by first probing
the network and learning the server certificate hash based on the new
events and then adding a network configuration with the server
certificate hash after user have accepted it. Future connections will
then be allowed as long as the same server certificate is used.
Authentication server probing can be done, e.g., with following
configuration options:
eap=TTLS PEAP TLS
identity=""
ca_cert="probe://"
Example set of control events for this:
CTRL-EVENT-EAP-STARTED EAP authentication started
CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21
CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected
CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' hash=5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a
CTRL-EVENT-EAP-TLS-CERT-ERROR reason=8 depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' err='Server certificate chain probe'
CTRL-EVENT-EAP-FAILURE EAP authentication failed
Server certificate matching is configured with ca_cert, e.g.:
ca_cert="hash://server/sha256/5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
This functionality is currently available only with OpenSSL. Other
TLS libraries (including internal implementation) may be added in
the future.
The three existing enums were already depending on using the same
values in couple of places and it is just simpler to standardize on
one of these to avoid need for mapping between different enums for
the exact same thing.
Get rid of wpa_supplicant_sta_rx() and add a new driver event that is
marked to be used only with driver_test.c. In addition, remove this
functionality from privsep wrapper. This is only use for client mode
MLME testing with driver_test.c.
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.
In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
This removes need for local configuration to ignore *.o and *~
and allows the src/*/.gitignore files to be removed (subdirectories
will inherit the rules from the root .gitignore).
Note: This changes values for existing NL80211_ATTR_MAX_SCAN_IE_LEN
and NL80211_ATTR_KEY_TYPE (for some reason, they ended up getting
swapped in wireless-testing.git) and as such, could break Michael
MIC error reporting (well, at least partially).
This commit merges the driver_ops structures and implementations from
hostapd/driver*.[ch] into src/drivers. This is only an initial step and
there is room for number of cleanups to share code between the hostapd
and wpa_supplicant parts of the wrappers to avoid unnecessary source
code duplication.
Move the shared IEEE 802.11w enum definition into src/common/defs.h to
avoid redefinition when both configuration structures are included into
the same file.
This can be used, e.g., with mac80211-based Linux drivers with
nl80211. This allows over-the-air FT protocol to be used (IEEE
802.11r).
Since the nl80211 interface needed for this is very recent (added
today into wireless-testing.git), driver_nl80211.c has backwards
compatibility code that uses WEXT for association if the kernel does
not support the new commands. This compatibility code can be
disabled by defining NO_WEXT_COMPAT. That code will also be removed
at some point to clean up driver_nl80211.c.
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.
