Jouni Malinen efd5d26d33 Remove unnecessary wpa_ie_len check from wpa_parse_wpa_ie_wpa()
There is no need to have a separate "fail silently" case for wpa_ie_len
== 0. That condition does not seem to be reachable and even if it were,
the following "ie len too short" case will result in the exact same
return value.

Jouni Malinen ce8963fc9f Remove WEP40/WEP104 cipher suite support for WPA/WPA2
As far as IEEE 802.11 standard is concerned, WEP is deprecated, but at
least in theory, allowed as a group cipher. This option is unlikely to
be deployed anywhere and to clean up the implementation, we might as
well remove all support for this combination.

org.wi-fi.wfds service is not a replacement for non-WFA service matches.
Do not try to replace the results with that if there is not sufficient
room for the response. Instead, reply with all the matching services

When hostapd or wpa_supplicant is run in debug more with key material
prints allowed (-K on the command line), it is possible for passwords

Andrei Otcheretianski 8f52409972 P2P: Prefer direct Probe Response frames over GO's client list
A P2P Client may be discoverable and reply to Probe Request frames,
while at the same time the P2P GO would also be discoverable and include
the P2P Client information in the P2P Group Info attribute of the Probe
Response frames.

If a seeker constantly hears the Probe Response frames from a P2P Client
and then from the GO, but handles them in the opposite order (due to
scan results ordering), the more valuable Probe Response frame from the
P2P Client will be ignored. Fix this by defining a threshold (1 second)
during which the direct Probe Response frame will be preferred over the
information acquired from the GO and will not be considered as old.

Michael Braun 132dfbe8c2 Fix removal of tagged interface and bridge when multiple BSS share them
Currently, if multiple bss share are bridge and tagged vlan interface,
only the first instance of struct hostapd_vlan for this vlanid will have
the DVLAN_CLEAN_VLAN flag added. Thus, when this instance is removed,
the tagged vlan interface will be removed from bridge, thought other bss
might still need it. Similarily, the bridge will be left over, as the
does not have zero ports when the first instance of a struct
hostapd_vlan is freed.

This patch fixes this by having a global (per process) reference counter
for dynamic tagged vlan and dynamically created bridge interfaces, so
they are only removed after all local users are freed. (struct
hapd_interfaces *)->vlan_priv is used to hold src/ap/vlan_init.c global
per-process data like drv_priv does; right now this is only used for the
interface reference counting, but could get extended when needed. Then
possibly some vlan_global_init / vlan_global_deinit should be added, but
this is not required right now.

Additionally, vlan->configured is checked to avoid reference counter
decreasing before vlan_newlink increased them.

In order to avoid race conditions, vlan_dellink is called explicitly
after hostapd_vlan_if_remove. Otherwise there would be a short timeframe
between hostapd_vlan_if_remove and vlan_dellink during which the struct
hostapd_vlan still exists, so ap_sta_bind_vlan would try to attach
stations to it.

the following email:

 From: Yaron Sheffer <yaronf.ietf at gmail.com>
 To: ietf at ietf.org
 Date: Wed, 17 Nov 2010 13:13:42 +0200

Expanding on my previous response, I suggest to resolve Bernard's
concern by adding the following text:

5.6 EAP Key Generation

EAP-EKE can be used for EAP key generation, as defined by [RFC 5247].
When used in this manner, the values required to establish the key
hierarchy are defined as follows:

- Peer-Id is the EAP-EKE ID_P value.
- Server-Id is the EAP-EKE ID_S value.
- Session-Id is the concatenated Type | Nonce_P | Nonce_S, where Type is
  the method type defined for EAP-EKE in [Sec. 4.1], a single octet.
