If parsing of the certificate or private key succeeds using any of
the tried encoding types, clear the OpenSSL error queue without
showing the pending errors in debug log since they do not really
provide any useful output and can be confusing.
GO may use M2D to notify that PBC overlap was detected if the GO was
configured to allow only a specific P2P Device to connect using PBC.
We need to report the M2D message on the parent interface if a
separate group interface is used. In addition, we can stop the P2P
operation if PBC overlap was indicated similarly to what we are
already doing in th case the overlap is detected locally.
Some of the wpa_supplicant control interface commands, like WPS_PIN,
may not include a newline in the end of the response. This can result
in the response being lost when wpa_cli redraws the screen after an
event message. Add a newline after such responses in interactive mode
to avoid the problem.
This patch fixes a problem I had when I tried to connect
an embedded system [wpa_supplicant, CONFIG_TLS=internal]
to my TLS secured network.

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.

When FT protocol run is completed with FT-EAP, the EAPOL state machine
needs to be notified of the completed authentication to make sure it
does not try to start new authentication.
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.
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.
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.
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.
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 allows the interface name to be automatically
added to log file lines by the core logging logic.

This makes log files much more readable if multiple interfaces
are being controlled by the same process. The interface name is
added to stdout/file/syslog entries, but not to the messages

If the driver advertises max_remain_on_chan data, use it instead of
the hardcoded value of 5000. Keep the default at 5000 since that is the
value used by earlier versions of cfg80211/mac80211 and not advertised
in nl80211 for those.

There are two issues with p2p_long_listen:
1) max_remain_on_channel is assumed to be 5 seconds,
2) if max_remain_on_channel is not a full multiple of
seconds, accounting breaks.
Fix these by converting p2p_long_listen to ms and
tracking it according to max_remain_on_channel.

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.

If WMM is not disabled explicitly (wmm_enabled=0 in hostapd.conf),
enable WMM automatically whenever HT (ieee80211n) is enabled. Use
the default WMM parameters for AP TX queues and the EDCA parameters
advertised for stations in WMM IE if no overriding values are
included in the configuration.
When using FT-EAP, the second half of MSK is used as the starting
point for PMK key hierarchy. Configure that instead of the first
half of MSK when using FT with driver-based 4-way handshake and
FT protocol.
This was previously done for WPA/WPA2-Personal as part of association
processing when the driver is implementing 4-way handshake. The
portValid needs to be done for WPA/WPA2-Enterprise to get the proper
EAPOL authentication completed callback to configure PMK to the driver.
We can use the P2P interface types to check if the driver supports P2P
and to tell the kernel that a given interface is going to be used for
P2P (when it is created).

This patch makes it to show "FAIL".
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
In order to enable protection mechanisms for different HT opmodes the
driver needs to be aware of the current HT opmode that is calculated by
hostapd. Hence, pass the current opmode to the nl80211 driver via
the bss attribute NL80211_ATTR_BSS_HT_OPMODE.
