Wait for connection (IBSS join completed) event before marking state
completed. In addition, do not use the station mode authentication
timeout since that can trigger full disconnection from IBSS when
there is a timeout with just one of the peers.
Initialize the new DBus API before the old one, so new applications
which can use both, the old and the new API will be notified first
that new API is available.
cfg80211/mac80211 can get into somewhat confused state if the AP only
disassociates us and leaves us in authenticated state. For now, force
the state to be cleared with deauthentication to avoid confusing errors
if we try to associate with the AP again. This gets rid of 30 second
delay (scan timeout) in cases where only a disassociation frame is
received from the AP.
8a5ab9f5e5 fixed global driver context
for init2(), but it also broke driver initialization with driver
wrappers that do not use init2().. Fix this by setting wpa_s->global
before it gets dereferenced.
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 avoids passing the raw scan results into the RSN code and by
doing so, removes the only dependency on src/drivers from the
src/rsn_supp code (or from any src subdirectory for that matter).
Use shared functions for converting Primary Device Type between binary
and string formats. In addition, use array of eight octets instead of a
specific structure with multiple fields to reduce code complexity.
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.
These driver wrappers should not be used anymore; WEXT should be used
instead. However, there may still be users stuck on older kernel versions
that may require driver specific wrappers, so the source code still
remains in the repository.
Clean up driver interface by merging hostapd and wpa_supplicant
specific set_beacon driver_ops into a single one. In addition,
merge set_beacon_int into to the same operation.
This removes many of the cases where moving to the WPS tab can be
undesired. It is really only useful if we are not currently connected
and there is an AP available that would likely be able to provide us
network connectivity with use of WPS (active PBC more or selected
registrar set).
Clean up the peer dialog information to be more user friendly. Only
show the device type in the tooltip and move the verbose details into
a separate area in a new Properties dialog. The new dialog will also
show some of the standard fields with titles to make them easier to
read.
The Enrollee entry may be deleted while the PIN query dialog is open.
To avoid crashing on using freed entry, copy the needed data into
local variables before and use the local data after the PIN dialog
has been closed.
The peer entries are now using different icons based on their type. As
a starting point, a separate AP and laptop icons are used. More icons may
be added in the future to mark different device types (e.g., based on
primary device type information from WPS).
When using umask 0077, the control interface directory was left without
group read/execute permissions even if the configuration file explicitly
asked for the group to be allowed to access the control interface. Fix
this by adding read/execute permissions for group if a specific group is
defined in the configuration. [Bug 199]
Change the dbus policy file to only allow root applications to receive
signals from wpa_supplicant. This keeps WPS Credentials data secret
from non-root listeners.
When trying to build wpa_gui (Qt4 version) from openembedded it fails
because Qt4 is compiled without session manager and thus wpa_gui fails
to compile.
I attached a patch, that enables compiling without Session Manager (via
preprocessor) if it is not compiled into Qt4; otherwise, it behaves as
it does right now.
I checked to build on my host (Debian unstable, Session Manager
enabled) and openembedded (Session Manager disabled).
This will need some additional code in wps_er_pbc() to handle PBC mode
enabling for a single AP only. For now, this can only be expected to work
when the ER is connected to a single AP.
Clean up registration of large number of dbus method/property/signal
handlers by using arrays containing all the information needed to call
the registration functions.
New PINs can now be added to WPS ER. This results in the ER code
using SetSelectedRegistrar to modify AP state so that Enrollees
will be able to notice the actice registrar more easily.
Smartcard parameter update via DBus ended up re-initializing the EAPOL
state machine without updating the pointer inside WPA state machine.
This can trigger a segfault when EAP layer attempts to use the old
reference. Fix this by re-initializing the pointer inside WPA state
machine.
Better make sure we do not end up writing over the end of the local
registered_sig buffer regardless of how many arguments are used in
dbus method description.
There is no point checking whether wpa_s is not NULL after having
dereferenced it earlier in the function.. Furthermore, there is no
need to use a local variable for wpas_dbus_get_path() result.
The cleanup routine in the end would have dereferenced props pointer
which could be NULL. There is no need to go through that cleanup code
in this case, so just exit from the function with return instead.
ssid could be NULL here at least based on the function documentation,
so better check whether that is the case prior to calling the
notification function.
Commit d3a9822542 broke per-SSID scan
by using the ssid variable for internal loop and by doing so,
overriding the value that was needed below to figure out whether the
scan is for a specific SSID. Fix this by using a temporary variable
instead when looping over network finding which frequencies to scan for.
This was triggering some gcc versions to warn about strict aliasing.
Since the typecast is not really needed here, the cleanest way to get
rid of the warnings is to just use the correct type for the local
variable.
This is like wpa_msg(), but the output is directed only to
ctrl_interface listeners. In other words, the output will not be
shown on stdout or in syslog.
Change scan result reporting to use wpa_msg_ctrl() for
CTRL-EVENT-SCAN-RESULTS message at info level and wpa_printf() at
debug level to avoid showing scan result events in syslog in the
common configuration used with NetworkManager.
This patch implements the new DBus API. Both, the new and the
previous API may work concurrently and may be turned on or off
separately in .config file.
Some features of the new API are:
- more wpa_supplicant's events are signaled with DBus signals,
- introspection data (requires libxml2 and may be disabled),
- CurrentBSS and CurrentNetwork properties,
- PropertyChanged signal for most of properties,
- Relatively easy to extend.
.config options for the new API are: CONFIG_CTRL_IFACE_DBUS_NEW=y and
CONFIG_CTRL_IFACE_DBUS_INTRO=y for introspection.
This commit misses couple of parts from the full implementation
(these are still under review):
- fetching all configuration parameters for learning WPS information
- scan result BSS add/remove notification (register_bss() and
unregister_bss() notification callbacks)
Clean up code so that UPnP implementation does not need to include all
the HTTP functionality. In addition, make it easier to share HTTP server
functionality with other components in the future.
Instead of implementing HTTP client functionality inside
wps_upnp_event.c, use a generic HTTP client module to do this. The HTTP
client code can now be shared more easily for other purposes, too.
This is the first step in adding support for using wpa_supplicant as a
WPS External Registrar to manage APs over UPnP. Only the device
discovery part is implemented in this commit.
New wpa_supplicant command line options -o<driver> and -O<ctrl> can
now be used to override the parameters received in add interface
command from dbus or global ctrl_interface. This can be used, e.g.,
to enable control interface when using NetworkManager (add
-O/var/run/wpa_supplicant into the Exec parameter in
/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service).
Similarly, this can be used to use another driver wrapper with
NetworkManager (e.g., -onl80211 to replace WEXT with nl80211).
This provides information about PBC mode result from the WPS Registrar
module. This could be used, e.g., to provide a user notification on the
AP UI on PBC failures.
Force deauthentication from the AP to clear mac80211 state (it would get
stuck with future scans if the AP is left in authenticated, but not
associated, state).
Add blacklist entry for the AP to allow other APs with worse signal
strength to be tried (e.g., when APs are trying to do load balancing
with status code 17). Reduce wait for the next scan to speed up
connection in cases where there could be other APs that could accept
association, but which show worse signal strength.
This functionality fits better with src/tls (i.e., internal TLS
implementation), so move it there to make crypto_internal.c more
of a wrapper like other crypto_*.c files.
Previously, APs that were hiding SSID (zero-length SSID IE in
Beacon frames) could have been selected when wildcard SSID matching
was used. This would result in failed association attempt since
the client does not know the correct SSID. This can slow down WPS
which is often using wildcard SSID matching.
Ignore BSSes without known SSID in the scan results when selecting
which BSS to use.
This patch completely separates supplicant's code from dbus.
It introduces three new notifications which copes with all
remaining dbus stuff.
wpas_notify_unregister_interface() was renamed to
wpas_notify_iface_removed().
The hostapd/wpa_supplicant compilation failed with CONFIG_IEEE80211R=y
or CONFIG_IEEE80211W=y option if CONFIG_EAP_PSK and CONFIG_EAP_GPSK are
not used.
mac80211 does not currently allow (re)authentication when we are already
authenticated. In order to work around this, force deauthentication if
nl80211 authentication command fails with EALREADY. Unfortunately, the
workaround code in driver_nl80211.c alone is not enough since the
following disconnection event would clear wpa_supplicant authentication
state. To handle this, add some code to restore authentication state
when using userspace SME.
This workaround will hopefully become unnecessary in some point should
mac80211 start accepting new authentication requests even when in
authenticated state.
