ba2a573c5f Rename "broadcast SSID" to "wildcard SSID"
"Wildcard SSID" is the term used in IEEE Std 802.11-2007, so it is a
better name for the zero-length SSID used in Probe Request.

6a1063e008 driver_nl80211: Add support for multi-SSID scan requests 2009-02-14 21:17:46 +02:00

e76baaac0c Add support for multi-SSID scan requests
If the driver reports support for more than one SSID per scan request,
optimize scan_ssid=1 operations in ap_scan=1 mode. This speeds up
scanning whenever scan_ssid=1 is used since the broadcast SSID can be
included in every scan request and if driver supports more than two
SSIDs in the scan request, the benefits are even larger when multiple
networks have been configured with ap_scan=1.

This is also cleaning up wpa_supplicant_scan() function by moving code
around so that the SSID list is not processed unnecessarily if the
operation mode does not need this.

f55b218a5c driver_test: Implement scan2() handler
This does not actually send out separate scan requests for each SSID,
but the debug output can be used to test scan2() functionality with
multiple SSIDs.

fc2b7ed5f3 Add extended driver scan request command: driver_ops::scan2()
This can be used to provide support for scanning multiple SSIDs at a
time to optimize scan_ssid=1 operations. In addition, Probe Request IEs
will be available to scan2() (e.g., for WPS PBC scanning).

362f781e1c Allow multiple driver wrappers to be specified on command line
For example, -Dnl80211,wext could be used to automatically select
between nl80211 and wext. The first driver wrapper that is able to
initialize the interface will be used.

7d315b7b42 nl80211: Remove one second sleep after iface up
This workaround was needed with some drivers that used WEXT, but there
is no known nl80211-enabled driver that would need this, so lets get rid
of the extra delay.

80bc75f135 New driver capability info: max number of scan SSIDs
The driver wrappers can now inform wpa_supplicant how many SSIDs can
be used in a single scan request (i.e., send multiple Probe Requests
per channel). This value is not yet used, but it can eventually be used
to allow a new scan command to specify multiple SSIDs to speed up
scan_ssid=1 operations. In addition, a warning could be printed if
scan_ssid=1 is used with a driver that does not support it
(max_scan_ssids=0).

ec1020512c wpa_gui-qt4: Add support for selecting between WEP open/shared key auth
Split the auth=none option into three: open, WEP, WEP with shared key to
allow the user specify WEP with shared key authentication. In addition,
fix static WEP key edits to be enabled only when using static WEP keys
(i.e., not for IEEE 802.1X).

e1b525c356 Use signal quality if level is not available for comparing max rates
Some drivers (for example ipw2100) do not report signal level but only
signal quality. wpa_supplicant already uses the signal quality if no
level is reported and all other comparision parameters are equal to sort
the scan results. However, if two APs have different max rates and the
signal level does not differ much wpa_supplicant chooses the AP with the
higher max rate.

In case of ipw2100 no signal level is reported and thus wpa_supplicant
always takes the AP with higher max rate even if its signal quality is
really low. For example if AP1 (max rate 11Mb/s, 80% signal quality) and
AP2 (max rate 54 Mb/s, 20% signal quality) are found by a scan
wpa_supplicant would choose AP2.

Hence, if no signal level is reported depend on the signal quality if
max rate should be compared. A quality difference of 10% is considered
acceptable in favor of the higher max rate.

b965fa7294 wext: really disassociate (set random SSID)
Really disassociate when tearing stuff down; drivers may sometimes
(legally) keep trying to reassociate unless the BSSID is unlocked.  If
the SSID is unlocked too, under WEXT drivers are able to pick an SSID to
associate, so kill that behavior by setting a bogus SSID.  Unfortunately
WEXT doesn't provide an easy method to say "stop whatever doing and just
idle".

34a6c94178 WPS: Fix clearing of WPS IE with madwifi driver
On WPS init/deinit process, the hostapd clears it's own WPS IE
with 0 length WPS IE. But it fails. Because the parameter to
ioctl is too short. Then hostapd prints a below message.

edd757e8a3 Use larger buffer for TLS encryption to avoid issues with GnuTLS
It looks like GnuTLS (at least newer versions) is using random padding
on the application data and the previously used 100 byte extra buffer
for tls_connection_encrypt() calls was not enough to handle all cases.
This resulted in semi-random authentication failures with EAP-PEAP and
EAP-TTLS during Phase 2.

Increase the extra space for encryption from 100 to 300 bytes and add an
error message into tls_gnutls.c to make it easier to notice this issue
should it ever show up again even with the larger buffer.

c3f5b1e16d Send a dbus reply only if requested by the caller
wpa_supplicant should not send a dbus reply as response to a method call
if no reply was requested by the caller. Sending a reply even if not
requested is basically no problem but triggers dbus warnings like the
one below.

b93b6004e4 WPS: Allow minor version differences in Version attribute check

b77eab282a Explicitly link against libdl when including TNC support
If you don't choose OpenSSL as TLS implementation and choose to enable
CONFIG_EAP_TNC you have to link against libdl. The OpenSSL libraries
implicitly link against them, so this might be a reason why it wasn't
noticed yet. I assume the same applies to hostapd.
