We can now handle up to 65535 byte result buffer which is the maximum
due to WEXT using 16-bit length field. Previously, this was limited to
32768 bytes in practice even through we tried with 65536 and 131072
buffers which we just truncated into 0 in the 16-bit variable.
This more or less doubles the number of BSSes we can received from scan
results.
If wpa_supplicant is started with -u but the DBus service is already
registered wpa_supplicant will bail out. However, it will segfault
in wpa_supplicant_deinit because global->drv_priv wasn't allocated
yet.

This is based on a patch from Pavel Roskin <proski@gnu.org>, but with
the WIRELESS_DEV part removed instead of moved since it does not apply
anymore. Additional note on client MLME limitations was also added.
MadWifi is unlikely to be in ../head relative to hostapd or
wpa_supplicant, as it would be inside the hostap git repository.
MadWifi sources are more likely to be in a directory called "madwifi"
and residing outside the hostap repository. Using "madwifi" also
demonstrates that the top-level madwifi directory is needed.
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.
The default interval is now 5 seconds (used to be 1 second for
interactive mode and 2 seconds for wpa_cli -a). The interval can be
changed with -G<seconds> command line option.
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.
The wps_cred_process option can be used to configure wpa_supplicant to
send received Credential attributes for external processing over
ctrl_iface and dbus. This allows external programs to update their
configuration when WPS is used to provision new networks.
This makes it easier to pass the credential data to external programs
(e.g., Network Manager) for processing. The actual use of this data is
not yet included in hostapd/wpa_supplicant.
The current implementation does not support WPA/WPA2-Enterprise
credentials. Ignore any credential that is using unsupported
authentication type to avoid potential issues with partially configured
network blocks.
Must not set pairwise_cipher/group_cipher for non-WPA/WPA2 networks
since the configuration parser is going to reject such values. In
addition, should not limit group_cipher to just TKIP or TKIP|CCMP just
in case the AP is using WEP as the group cipher. Default group_cipher
value can be used for all cases.
RSN IBSS uses authentication per-STA and that is initialized separately,
so there is no need to enable the per-BSS like authentication that is
used with APs.
This makes wpa_gui remember whether it was only in the tray when the
session was terminated and starts only in the tray if session manager
restarts it automatically.
This commit adds a new build option, CONFIG_IBSS_RSN=y, that can be used
to enable RSN support for IBSS. This links in RSN Authenticator code
from hostapd and adds code for managing per-peer information for IBSS. A
new wpa_cli command or driver event can be used to request RSN
authentication with an IBSS peer. New RSN Authenticator and Supplicant
will be allocated for each peer.
The basic state machine setup code is included in this commit, but the
state machines are not properly started yet. In addition, some of the
callback functions are not yet complete.
Do not add the automatically generated RADIUS attributes NAS-IP-Address,
Calling-Station-Id, Framed-MTU, NAS-Port-Type, and Connect-Info if -N
option is used with the same attribute type. This allows these
attributes to be replaced without causing duplicate entries.
Fix compile warning by renaming gridLayout to wpsGridLayout in

Also disable WPS tab if the running supplicant doesn't support that,
just as the WPS action menu is.

It is better to have command description around the command definitions:
the chances for omitting usage, forgotting to change/delete them, etc.
are smaller than for the separate usage statement. [Bug 290]

I had added flags to the every command description: just now the only
meaningful flag tells that this command has sensitive arguments and it
shouldn't be written to the disk. I rewrote the logics for the search
for the sensitive commands: special procedure is now loops over all
commands and tries to see if command has sensitive data. [Bug 289]

First of all, the history had not been written to the disk, since almost
all commands were cleaned up due to the error in the history cleaning:
the return value of the last os_strncasecmp() call was not compared to
zero, but was rather used as is. So the condition was almost always
true and most commands were removed from the history.
The second problem was that the evaluation of the potentially sensitive
commands was started at the entry number 1, instead of very first entry.
This change replaces -I and -i options (Chargeable-User-Identity) with a
new -N option that can add any RADIUS attribute into the Access-Request
messages without having to modify eapol_test for each new attribute.
Replace " wpa_supplicant" with " %wpa_supplicant" except for
"struct wpa_supplicant". This makes it easier to write Doxygen comments
since there is no need to add the ugly '%' prefix to each instance of
wpa_supplicant text showing up.
This updated all doxygen runs to use the same style that was used for
wpa_supplicant full documents. The full vs. fast configurations are now
otherwise identical apart from fast not generating dot files or
latex/pdf version of the documentation.
Generate a SHA1 hash -based UUID from the local MAC address if the UUID
was not configured. This makes it easier to prepare for WPS since there
is no need to generate an UUID.
When using ap_scan=1, we know before the association request that MFP
will be supported, so we can as well require it. This helps mac80211 in
configuring whether to enable MFP.
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.
It seems that for WPS registration we should use the same authentication
timeout as for ieee8021x, no? (See patch attached.) On slow platforms
public keys computation may take around 4-5 seconds (we actually stuck
on this issue).
Set ctrl_interface to non-empty value in INTERFACE_ADD to avoid
ctrl_iface.c assuming the control interface is not to be enabled. This
fixes the dynamically added interface to use control interface.
The NSIS installer will now add Windows registry entries for
wpa_supplicant during installation and removes them during
uninstallation. This allows wpa_gui to start wpasvc and add new
interfaces without requiring the user to do any manual registry
editing.
"Add interface" command in File menu can now be used to add a new
network interface to running wpa_supplicant (using INTERFACE_ADD control
interface command). In addition, the network interface is added into
Windows registry (with skip_on_error) for future use. This functionality
is currently enabled only for Windows builds. The user is also prompted
about the possibility of adding an interface if no interfaces are
enabled. This makes it easier to get started without having to touch
registry manually.
This can be used to include binding information for multiple interfaces
in Windows registry and only use the ones that match with an available
network interface.
The new INTERFACE_LIST global control interface command can be used to
request a list of all available network interfaces that could be used
with the enabled driver wrappers. This could be used to enable
interfaces automatically by external programs (e.g., wpa_gui).
Driver wrappers can now register global_init() and global_deinit()
driver_ops handlers to get a global data structure that can be shared
for all interfaces. This allows driver wrappers to initialize some
functionality (e.g., interface monitoring) before any interfaces have
been initialized.
UUID-E is not required to be present in Beacon frame, so we need to
accept scan results that do not have UUID-E as a valid PBC situation as
long as not more than one AP is in active PBC mode.
wpa_gui will now ask user whether the wpasvc service should be started
if it is not running. In addition, File menu has items for starting and
stopping the service.
Change association behavior to match with ap_scan=1 when WPS is used in
ap_scan=2 mode with wildcard SSID matching. In addition, allow hardcoded
BSSID to be used to select AP even if selected registrar attribute is
not present.
A separate cross compiler mkspecs file (win32-x-g++) is now used to
configure all build options so the setup-mingw-cross-compiling hack is
not needed anymore. Furthermore, the MinGW setup is now on path, so no
need to specify extra PATH changes for it.
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).
We need to be a bit more careful when removing the WPS configuration
block since wpa_s->current_ssid may still be pointing at it. In
addition, registrar pointer in wps_context will need to be cleared
since the context data is now maintained over multiple EAP-WSC runs.
Without this, certain WPS operations could have used freed memory.
The specific AP (BSSID) can now be selected through scan results for
WPS (WPS pushbutton on the network configuration dialog). When a BSSID
is selected, AP device PIN (e.g., from a label) can be used to configure
the AP by acting as a Registrar.
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.
Windows Server 2008 NPS gets very confused if the TLS Message Length is
not included in the Phase 1 messages even if fragmentation is not used.
If the TLS Message Length field is not included in ClientHello message,
NPS seems to decide to use the ClientHello data (excluding first six
octets, i.e., EAP header, type, Flags) as the OuterTLVs data in
Cryptobinding Compound_MAC calculation (per PEAPv2; not MS-PEAP)..
Lets add the TLS Message Length to PEAPv0 Phase 1 messages to get rid of
this issue. This seems to fix Cryptobinding issues with NPS and PEAPv0
is now using optional Cryptobinding by default (again) since there are
no known interop issues with it anymore.
Changed peer to derive the full key (both MS-MPPE-Recv-Key and
MS-MPPE-Send-Key for total of 32 octets) to match with server
implementation.
Swapped the order of MPPE keys in MSK derivation since server
MS-MPPE-Recv-Key | MS-MPPE-Send-Key matches with the order specified for
EAP-TLS MSK derivation. This means that PEAPv0 cryptobinding is now
using EAP-MSCHAPv2 MSK as-is for ISK while EAP-FAST will need to swap
the order of the MPPE keys to get ISK in a way that interoperates with
Cisco EAP-FAST implementation.
