The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().
Instead of hardcoding the Config Methods attribute value in Probe
Request frames, set this based on the configured parameter
config_methods to allow correct set of methods to be advertised.
The device description file may include multiple devices. Improve the
simplistic parser by first trying to find the WFADevice:1 device before
fetching the device parameters. While this is still far from complete
XML parsing, this should address the most common root device
specifications.
This allows non-mac80211 drivers to report received Probe Request
frames to user space and Probe Response and Action frames to be sent
from user space when using AP/P2P GO mode.
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.
This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.
Extend the code that waits for the station to send EAPOL-Start before
initiating EAPOL authenticator operations to cover the case where the
station includes WPS IE in (Re)Association Request frame if that IE
does not include support for WPS 2.0. While this should not really
be needed, this may help with some deployed WPS 1.0 stations that do
not support EAPOL operations correctly and may get confused of the
EAP-Request/Identity packets that would show up twice if EAPOL-Start
is transmitted.
If an ER tries to send a message to a STA that is not in the middle
of WPS protocol, do not try to deliver that. This can help with issues
where an ER takes long time to reply to M1 and another Registrar has
already completed negotiation.
It is possible to get a response for a pending EAP callback after the
EAP state machine has already completed its work or has timed out. For
those cases, make sure that the callback function is not delivered since
it could result in NULL pointer dereferences.
The Config Methods attribute in M2 and M2D messages is supposed to
indicate which configuration methods are supported by the Registrar. As
such, it should not depend on whether PBC mode is currently active or
not. That will only affect the Selected Registrar Config Methods and
Device Password ID attributes.
This change is a first step in better supporting different driver
architectures for AP mode operations with nl80211. This commit in
itself does not add new functionality, but it makes it easier to add
new AP mode parameters to address needs of drivers that have more of
the MLME/SME in firmware or kernel.
Split WPA initialization into two parts so that the Beacon frames can be
configured fully before the initial keys (GTK/IGTK) are configured. This
makes it easier for drivers that depend on the AP security mode being
fully set before the keys are configured.
This avoids a request to the driver to first start beaconing before
the WPA/RSN IE has been generated and then immediately changing the
beacon IEs once the WPA/RSN IE is ready.
Such using params->wpa_ie to figure out whether the connection is for
WPA/WPA2 is not correct since that buffer is used also to add WPS IE. In
case of WPS, do not add NL80211_ATTR_WPA_VERSIONS to avoid confusing
drivers.
Some compilers complain about fwrite calls if the return value is
not checked, so check the value even if it does not really make
much of a difference in this particular case.
The internal TLS implementation assumes that the certificate chain
is ordered by issuer certificate following the certificate that it
signed. Add the certificates to the chain in suitable order when
loading multiple certificates.
Commit e1d526293b added code for verifying
whether the receive Probe Request frame was indicating support for only
802.11b rates, but it missed the for loop for the extended supported
rates element. Add that to fix the validation code for cases where
non-802.11b rates are in the extended supported rates element.
Currently, wpa_driver_nl80211_authenticate() changes the interface type

If the driver wrapper is setting up the interface up only at commit(),

Windows 7 uses incorrect way of figuring out AP's WPS capabilities by
acting as a Registrar and using M1 from the AP. The config methods
attribute in that message is supposed to indicate only the configuration
method supported by the AP in Enrollee role, i.e., to add an external
Registrar. For that case, PBC shall not be used and as such, the
PushButton config method is removed from M1 by default. If pbc_in_m1=1
is included in the configuration file, the PushButton config method is
left in M1 (if included in config_methods parameter) to allow Windows 7
to use PBC instead of PIN (e.g., from a label in the AP).
cfg80211 maintains separate BSS table entries for APs if the same
BSSID,SSID pair is seen on multiple channels. wpa_supplicant does
not use frequency as a separate key in the BSS table, so filter out
duplicated entries. Prefer associated BSS entry in such a case in
order to get the correct frequency into the BSS table.
It may take some time for the TX status to be delivered for a
(Re)Association Response frame and if any Data frames are received
during that time, they may end up getting dropped as Class 3 frames in
not-associated state. This results in a Disassociation frame being sent
to the station and it assuming that the association has been lost.
Work around the issue by remembering that the (Re)Association Request
has already been accepted and skip the Deauth/Disassoc sending because
of the possible Class 3 frames before the TX status callback is
received.
In theory, these calls could fail, but it is not really likely to
happen in practice in the use case here. Anyway, check that they do
not return an error before accepting the length of the file.
This function does not get called with in_data == NULL in practice, but
it seems to be at least partly prepared for that case, so better make it
consistent by handling the NULL value throughout the function.
Both the SA and IEs from the received Probe Request frames must be
included and the Probe Request RX callback functions may assume that
these are not NULL.
The change to use wpa_dbg() in wpa_sm_parse_own_wpa_ie() could result
in a NULL pointer dereference if the function were called when WPA
state machine has not been initialized. While this cannot really
happen in practice, it is better to be prepared for that since that
was the case before the wpa_dbg() change.
The size_t value here can be 64-bit and result in implicit sign
extension. In this particular case, that gets masked out by
host_to_be32(), so there is no practical difference, but it is better
to get rid of the 64-bit variable explicitly.
The supportedTypes parameter is a list of TNC_MessageType values
and the buffer to be copied should use size of TNC_MessageType, not
TNC_MessageTypeList. In practice, these are of same length on most
platforms, so this is not a critical issue, but anyway, the correct
type should be used.
This avoids reading past the end of the IE buffer should the FTIE
be too short. In addition, one debug hexdump was using uninitialized
pointer to the FTIE buffer, so fixed it to use the pointer from the
parse data.
AF_INET6 is not always enabled by default, so use AF_INET instead. In
addition, use the old fixed length, 2048, as a failover value if the
sysctl fails for any reason.
Commit 03d3f28a69 broke initialization of
EAPOL authenticator state machines since an error value from
wpa_auth_sta_key_mgmt() (-1) was not handled properly and the fixed
wpa_key_mgmt_wpa_psk() identified the value as a PSK-based AKM because
of all bits being set to 1. The special error value needs to handled
separately to avoid skipping EAPOL state machine initialization.
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.
When the SME is in the driver or cfg80211, the automatic selection
of auth_alg is done by leaving out the NL80211_ATTR_AUTH_TYPE
attribute from the NL80211_CMD_CONNECT command.
This should fix EAPOL reauthentication and rekeying timeout issues
with Intel clients when using WMM (e.g., with IEEE 802.11n). These
stations do not seem to be able to handle EAPOL data frames as
non-QoS Data frames after the initial setup.
This adds STA flags to hapd_send_eapol() driver op to allow
driver_nl80211.c to mark the EAPOL frames as QoS Data frame
when injecting it through the monitor interface.
This provides a means for the supplicant to directly request signal
quality metrics from the driver. This is useful, for example for
background scan algorithms that might ask desire this information
out-of-band with CQM events.

Some deployed supplicants update their SNonce for every receive
EAPOL-Key message 1/4 even when these messages happen during the
same 4-way handshake. Furthermore, some of these supplicants fail
to use the first SNonce that they sent and derive an incorrect PTK
using another SNonce that does not match with what the authenticator
is using from the first received message 2/4. This results in
failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission
timeout is reached. The timeout for the first retry is fixed to
100 ms in the IEEE 802.11 standard and that seems to be short
enough to make it difficult for some stations to get the response
out before retransmission.
Work around this issue by increasing the initial EAPOL-Key 1/4
timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station
acknowledges reception of the EAPOL-Key frame. If the driver does
not indicate TX status for EAPOL frames, use longer initial
timeout (1000 ms) unconditionally.
Store Manufacturer, Model Name, Model Number, and Serial Number
attributes for P2P peers and expose these through the existing
peer information mechanisms.
Previously, a bug in GKeyDoneStations count would remain in effect
until the authenticator is restarted. Make this more robust by
clearing the station count before each rekeying setup. While this
is not really supposed to be needed, there has been bugs in this
area in the past and it is safer to make the implementation recover
from such an issue automatically.
If the STA to be freed is still included in GKeyDoneStations count,
decrement the count when the STA is freed. This does not happen in
AP mode since there is enough time to go through the authenticator
state machine to clear the STA. However, in the current RSN IBSS
implementation, the authenticator state for the STA is freed in a
way that does not allow the state machine to go through the clearing.
To address this, make sure that wpa_free_sta_sm() decrements the
GKeyDoneStations count if the STA happened to be in the process of
GTK rekeying.
CFLAGS += -DCONFIG_RSN_TESTING in .config and rsn_testing=1 in
hostapd.conf can now be used to enable a testing mode that adds

to the RSN element.
The AP code might, currently only in the case of HT40, defer actual
enabling to after a scan. In this case, the wpa_s AP code gets confused.
Add a callback for it to use and make it use it to finish only when the
setup has actually completed.
With appropriate hacks in place this allows using HT40 in P2P mode.

If there is already a link the requested peer, request start of

to allow some driver to accept the trigger for a new negotiation.
tdls_testing 0x80 can now be used to request wpa_supplicant to send
a TDLS Setup Request frame (i.e., try to initiate TDLS setup)
whenever a TDLS Setup Request frame has been received from a peer.
Blindly clearing all struct wpa_tdls_peer members is a risky
operation since it could easily clear pointers to allocated
memory, etc. information that really should not be removed.
Instead of hoping that new code gets added here to restore
the important variables, reverse the approach and only clear
structure members one by one when needed.
This allows the same code path to be used for both protected and
unprotected configurations to limit need for duplicated code in
both the driver and wpa_supplicant.
This adds code for validating that the same Key Lifetime is used
throughout TPK handshake and enables TPK lifetime expiration and
renewal/teardown. These part seem to be working, but the actual
handling of TDLS Setup Confirm and renewal are not fully
functional yet.
tdls_testing bits:
bit 3 = use short TPK lifetime (301 seconds)
bit 4 = use wrong TPK lifetime in TDLS Setup Response
bit 5 = use wrong TPK lifetime in TDLS Setup Confirm
These special test cases can be configured at run time with "wpa_cli
tdls_testing <value>" where <value> is an integer (either as a decimal
or as a hex value with 0x prefix) bitmap of special features with
following bits available at this point:
bit 0 = long frame (add dummy subelement to make FTIE very long)
bit 1 = use alternative RSN IE (different RSN capab value and no extra
replay counters)
bit 2 = send incorrect BSSID in Link Identifier of TDLS Setup Request
(e.g., 1 = long FTIE, 2 = different RSN IE, 3 = both of those)
This is disabled by default and can be enabled for the build by
adding the following line to .config:
CFLAGS += -DCONFIG_TDLS_TESTING
This allows driver wrappers to indicate whether the association was
done using Association Request/Response or with Reassociation
Request/Response frames.
CFLAGS += -DCONFIG_VALGRIND can now be used to enable support for
Valgrind client requests to help in removing some non-issues from
Valgrind reports. This is mainly aimed at allowing unknown ioctl
results to be marked as defined data.
If the os_time_t variable used for the expiration time (seconds)
overflows when the registered timeout value is being added,
assume that the event would happen after an infinite time, i.e.,
would not really happen in practice. This fixes issues with
long key timeouts getting converted to immediate expiration due
to the overflow.
os_snprintf() can be a preprocessor macro and according to
C99 (6.10.3 clause 11) the results of having preprocessor directives
inside the macro arguments is undefined.

When using multiple vifs and dynamic vlan tagging is enabled on any

Example:
wlan0 - xx:xx:xx:xx:x0
wlan1 - xx:xx:xx:xx:x1
Assume a STA connects to the AP interface wlan1 and gets a dynamic
VLAN tag 100 assigned by the RADIUS server. Hostapd will create an AP
VLAN interface wlan1.100 but doesn't set an address for this interface
which results in wlan1.100 getting the same address as wlan0:
wlan1.100 - xx:xx:xx:xx:x0
As a result the STA that was moved to wlan1.100 isn't able to finish its

the different address.
