97642d73ee wpa_gui-qt4: Disable WPS tab in the same way as the menu item
Disable by default and only enable if the running wpa_supplicant has
support for WPS. This is based on a patch from Kel Modderman
<kel@otaku42.de>.

6e488ff03c Remove orphaned wpa_cli control socket on EADDRINUSE
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]

1c5aeef0c2 Add comments on the new Broadcom driver not using driver_broadcom.c
The newer Broadcom driver ("hybrid Linux driver") supports Linux
wireless extensions and does not need (or even work) with the old
driver wrapper.

c9c3eafacb Remove unused variable from struct hostapd_config
I think that the "radius" pointer in the structure hostapd_config is
never used; when the configuration is parsed the related data is stored
in hostapd_bss_config's "radius" var.

f620268f13 WPS: Add support for external Registrars using UPnP transport
This adds mostly feature complete external Registrar support with the
main missing part being proper support for multiple external Registrars
working at the same time and processing of concurrent registrations when
using an external Registrar.

This code is based on Sony/Saice implementation
(https://www.saice-wpsnfc.bz/) and the changes made by Ted Merrill
(Atheros) to make it more suitable for hostapd design and embedded
systems. Some of the UPnP code is based on Intel's libupnp. Copyrights
and licensing are explained in src/wps/wps_upnp.c in more detail.

39034ce80f Fixed WPS Authenticator attribute processing after M2D
We must not replace M1 with M2D as the last_msg since we need M1 to
validate a possible M2 after M2D. Since M2D and ACK/NACK replies do not
include Authenticator attribute, we can just ignore M2D as far as
updating last_msg is concerned.

1e14526571 Use Data::Data only with Host AP driver; mac80211 can use Data::Nullfunc
The inactivity poll was originally supposed to use Data::Nullfunc, but
due to Prism2/2.5/3 firmware issues, this was changed to an empty
Data::Data frame. mac80211 does not have such an issue, so change the
inactivity poll frame to be Data::Nullfunc by default and use the
Data::Data workaround only with Host AP driver.

f01a6b1e3e driver_nl80211: Fixed inactivity poll status processing
Previous version was discarding TX status for FromDS data frames, but
those are the exact ones that we need to check for inactivity poll to
work, i.e., they are TX status reports for injected data frames.

In addition, remove the debug printing of TX status for data frame since
that could fill up the debug output if kernel-side filtering cannot be
used with monitor interface.

9616af520b driver_nl80211: use Linux socket filter to improve performance
TX status information for all transmitted data frames is not going to
be sent to hostapd anymore, so the CPU load with high traffic load is
going to be significantly reduced.

1a5a04c3de WPS: Add a workaround for incorrect passphrase encoding in Network Key

3b2cf800af WPS: Lock AP Setup on multiple AP PIN validation failures
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.

b385188de3 Add an EAPOL payload length workaround for a WPS implementation
Buffalo WHR-G125 Ver.1.47 seems to send EAP-WPS packets with too short
EAPOL header length field (14 octets regardless of EAP frame length).
This is fixed in firmware Ver.1.49, but the broken version is included
in many deployed APs. As a workaround, fix the EAPOL header based on the
correct length in the EAP packet. This workaround can be disabled with
eap_workaround=0 option in the network configuration.

a609915233 Allow WPS APs for PIN enrollment even without Selected Registrar
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.

b3ddab2122 WPS: Pad DH Public Key and Shared Key to 192 octets
WPS spec is not very specific on the presentation used for the DH
values. The Public Key attribute is described to be 192 octets long, so
that could be interpreted to imply that other places use fixed length
presentation for the DH keys. Change the DH derivation to use fixed
length bufferd by zero padding them from beginning if needed. This can
resolve infrequent (about 1/256 chance for both Public Key and Shared
Key being shorter) interop issues.

96fa129da9 Use WPS state Not Configured instead of Configured in Enrollee
This is needed to allow external Registrar (at least the implementation
in Windows Vista) to configure the Enrollee.

With this patch and my previous patch (for wps.c) , I could pass "Wi-Fi
WPS Test Plan Version 1.0 [5.1.4. Add to AP using PIN Config method and
PASS PHRASE through wired external registrar]".

e29bcf9eab WPS: Check Device Password ID attribute only if present in AP search
I can't pass the "Wi-Fi WPS Test Plan Version 1.0 [5.1.4. Add to AP
using PIN Config method and PASS PHRASE through wired external
registrar]". The wpa_supplicant-0.6.7 can't recoginize the testbed
AP(BCM94704AGRRev-E.2.4) as WPS PIN AP. Because after PIN entered, the
AP sends Selected Registrar attribute=0 and not send Device Password ID
attribute.

The proposed change as-is removed validation of Selected Registrar
attribute completely. However, that part is not included in this commit
since it can cause problems for environments with multiple WPS-enabled
APs. Another workaround for this will be considered in wpa_supplicant
scanning process (e.g., start trying to use WPS with APs that do not set
Selected Registrar to TRUE after couple of scan runs that do not find
any APs with Selected Registrar TRUE).

a60e7213e1 Fixed WPS with open and shared WEP networks
Do not initialize EAPOL state machine for the STA when hostapd is
configured to use WPS with open or shared WEP networks. This allows the
STA to use EAPOL-Start to indicate it wants to start WPS in such a case
and hostapd does not end up running through EAPOL authentication timeout
and disconnecting the STA if WPS is not used.

There was already code for starting EAPOL state machines based on
received EAPOL packets, but that was not working properly since
portEnabled was not set to TRUE on that code path. This is now fixed,
too.

aabe26a136 WPS: Added option to disable AP auto-config on first registration
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.

d745c7cc1a Added wps_cred_processing configuration option for hostapd
This behaves like the one in wpa_supplicant, i.e., hostapd can be
configured not to process new credentials (AP settings) internally and
instead pass the WPS attributes for an external program to process over
ctrl_iface.

adddffd129 Fixed MFP Association Comeback mechanism to use Timeout Interval IE
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.

7aab82b3fe Fixed WPS credential conversion to wpa_supplicant configuration
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.
