6a5200e699 atheros: Fix WEXT SIOCGIWESSID use with WE-21 and newer
The "too long" buffer (32+1 octets) prevented AP from starting up with
32 octet SSID with WE-21 and newer. Fix this by reducing the
SIOCGIWESSID buffer length.

c36d52427a nl80211: Support PMKSA candidate events
This adds support for RSN pre-authentication with nl80211 interface and
drivers that handle roaming internally (i.e., wpa_supplicant is not
responsible for requesting scan results that provide the needed
information without these events).

20f5a4c24c nl80211: Work around EALREADY from connect command
cfg80211 does not currently allow NL80211_CMD_CONNECT when there
is already an association. This can result in wpa_supplicant being
unable to request a connection if the interface is already in
connected state. Work around this by requesting disconnection if
the connect command fails with EALREADY error. This allows
wpa_supplicant to recover from the unexpected state and complete
the connect request on next attempt.

531e420dd7 Remove time.h include from utils/includes.h
os_*() wrappers should be used instead of functions from time.h.
Removing the header from includes.h enforces this. os_unix.c can
include this its uses are valid wrapper calls. wps_upnp.c uses

531f0331a1 nl80211: Cancel not yet started r-o-c
Currently, the following can happen:

1) P2P state machine requests R-O-C
2) user changes their mind and aborts
3) P2P state machine aborts R-O-C
4) driver_nl80211 rejects abort since there
   was no notification about the start yet
5) R-O-C period start notification from kernel
6) P2P state machine requests new R-O-C
7) this overlaps with old R-O-C -- iwlwifi driver
   can't handle that and returns -EBUSY
8) state machine stops dead in its tracks

The reason is that the abort isn't going through properly. Instead of
tracking whether a R-O-C is active in driver_nl80211, track whether one
was requested to avoid this scenario.

The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label

d8a790b922 Flush PMKSA cache entries and invalidate EAP state on network changes

all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).

The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the

for clearing the network_ctx values in the PMKSA cache.

cc28ad8cdf Fix Deauth/Disassoc callback handling with test frames
The Deauth/Disassoc TX status callbacks were ending up kicking the
station entry from kernel driver when test functionality was used to
inject Deauth/Disassoc frames from the AP with the purpose of leaving
the local association in place. Fix this by using STA flags to figure
out whether there was a pending callback for the frame that we need
to act on.

In addition, add forgotten functionality for the Disassoc TX status
callback to match the behavior with Deauth.

4dc03726de Delay STA entry removal until Deauth/Disassoc TX status in AP mode
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.

This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.

e4bf4db907 Work around SNonce updates on EAPOL-Key 1/4 retransmission
Some deployed supplicants update their SNonce for every receive
EAPOL-Key message 1/4 even when these messages happen during the
same 4-way handshake. Furthermore, some of these supplicants fail
to use the first SNonce that they sent and derive an incorrect PTK
using another SNonce that does not match with what the authenticator
is using from the first received message 2/4. This results in
failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission
timeout is reached. The timeout for the first retry is fixed to
100 ms in the IEEE 802.11 standard and that seems to be short
enough to make it difficult for some stations to get the response
out before retransmission.

Work around this issue by increasing the initial EAPOL-Key 1/4
timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station
acknowledges reception of the EAPOL-Key frame. If the driver does
not indicate TX status for EAPOL frames, use longer initial
timeout (1000 ms) unconditionally.

802.11n-2009 doesn't require HT Mixed Mode to be used in case of non-GF
STAs but instead the HT information element contains a flag if non-GF
STAs are present. All STAs are required to protect GF transmissions in

e926bcffd8 hostapd: Inherit correct MAC address for AP VLAN interfaces
When using multiple vifs and dynamic vlan tagging is enabled on any
interface, the created AP VLAN interfaces get the BSSID of the first
AP mode interface instead of the BSSID of the corresponding AP mode
interface.

Example:

wlan0 - xx:xx:xx:xx:x0
wlan1 - xx:xx:xx:xx:x1

Assume a STA connects to the AP interface wlan1 and gets a dynamic
VLAN tag 100 assigned by the RADIUS server. Hostapd will create an AP
VLAN interface wlan1.100 but doesn't set an address for this interface
which results in wlan1.100 getting the same address as wlan0:

wlan1.100 - xx:xx:xx:xx:x0

As a result the STA that was moved to wlan1.100 isn't able to finish its
4-way handshake since mac80211 won't pass its frames to wlan1.100 due to
the different address.

To fix this issue make use of the address of the AP interface when
creating an AP VLAN interface.

f39b07d7ed hostapd: Allow coexistance of HT BSSes with WEP/TKIP BSSes
In multi BSS setups it wasn't possible to set up an HT BSS in
conjunction with a WEP/TKIP BSS. HT needed to be turned off entirely
to allow WEP/TKIP BSSes to be used.

In order to allow HT BSSes to coexist with non-HT WEP/TKIP BSSes add a
new BSS conf attribute "disable_11n" which disables HT capabilities on a
single BSS by suppressing HT IEs in the beacon and probe response
frames. Furthermore, mark all STAs associated to a WEP/TKIP BSS as
non-HT STAs. The disable_11n parameter is used internally; no new entry
is parsed from hostapd.conf.

This allows a non-HT WEP/TKIP BSS to coexist with a HT BSS without
having to disable HT mode entirely. Nevertheless, all STAs associated to
the WEP/TKIP BSS will only be served as if they were non-HT STAs.

7e0318505c FT: Specify source MAC address for RRB messages
Use l2_packet with Ethernet header included so that the source
address for RRB packets can be forced to be the local BSSID. This
fixes problems where unexpected bridge interface address may end
up getting used and the recipient of the frame dropping it as
unknown R0KH/R1KH.

6603a96602 Flush STA entries in hostapd when clearing STAs from kernel
This is needed to keep kernel and hostapd in sync. In addition,
the obsolete entry in hostapd prevented use of Deauthentication
or Disassociation frame with reason code 6/7 mechanism to indicate
to the STA that there is no association if the STA missed the
broadcast Deauthentication frame for any reason.

e3e52e364e hostapd: Fix RADIUS client configuration update on reconfig
The internal pointer to RADIUS client configuration needs to be
updated whenever a new hostapd configuration is loaded. Without
this, freed memory may be dereferenced and this can result in
segmentation faults.

f049052b9e Use wpa_msg() instead of wpa_printf()
This converts number of debugging messages to use wpa_msg() in order
to allow the interface name to be shown with the messages.

A new function, wpa_dbg(), is introduced to allow
CONFIG_NO_STDOUT_DEBUG=y builds to remove the debug strings. This is
otherwise identical with wpa_msg(), but it gets compiled out if stdout
debugging is disabled.

This is needed to allows WPS PBC session overlap detection to work
with drivers that process Probe Request frames internally. This
code is is run in hostapd, but the wpa_supplicant AP mode did not
have call to the hostapd_probe_req_rx() function even though it
registered handlers for hostapd Probe Request RX callbacks.

d601247ca9 P2P: Allow WPS_PBC command on GO to select on P2P Device Address
An optional parameter, p2p_dev_addr, can now be given to WPS_PBC
command on P2P GO to indicate that only the P2P device with the
specified P2P Device Address is allowed to connect using PBC. If
any other device tries to use PBC, a session overlap is indicated
and the negotiation is rejected with M2D. The command format for
specifying the address is "WPS_PBC p2p_dev_addr=<address>", e.g.,
WPS_PBC p2p_dev_addr=02:03:04:05:06:07

In addition, show the PBC session overlap indication as a WPS failure
event on an AP/GO interface. This particular new case shows up as
"WPS-FAIL msg=4 config_error=12".

This makes log files much more readable if multiple interfaces

added to stdout/file/syslog entries, but not to the messages
sent to control interface monitors to avoid issues with parsing

1b4d379366 AP: Ensure ieee80211n_supported_ht_capab() gets called to check ht caps
ieee80211n_supported_ht_capab is called after ieee80211n_check_40mhz in
function hostapd_check_ht_capab. ieee80211n_check_40mhz can return 1 in
a valid scenario where the initialization is completed in a callback. In
this case ieee80211n_supported_ht_capab is skipped and hostapd does not
check the ht capabilities reported by the driver. Fix this issue making
sure ieee80211n_supported_ht_capab gets called.

df077c6262 Remove obsolete drivers wrappers: atmel, ndiswrapper, ipw, hermes
There is no real reason to maintain these in the current development
branch anymore. If someone really needs support for the obsolete
driver interfaces, these can be found in older wpa_supplicant
branches.

driver_atmel.c
- vendor-specific interface for ATMEL AT76C5XXx cards
- for some old out-of-tree driver; not for the upstream atmel*
  drivers

driver_ndiswrapper.c
- vendor-specific interface for an out-of-tree driver
- ndiswrapper should work with driver_wext.c, too

driver_ipw.c
- vendor-specific interface for old ipw2100/2200 driver
- the upstream driver works with driver_wext.c (and does not work
  with the old interface)

driver_hermes.c
- vendor driver that was not even included in the main wpa_supplicant
  releases
