e2670b1176 wpa_gui-qt4: Include cstdio to avoid some compiler issues
It looks like some build systems do not find snprintf() here unless
cstdio is included explicitly.

f05c7194cd wpa_gui-qt4: Add a new window for showing peer information
This provides some initial functionality for showing peer information,
i.e., showing information about other devices that has been discovered.
Currently, information is only available in the AP mode (list of
associated stations), but this is expected to increase in the future
(e.g., show the current AP in station mode, other stations in IBSS,
etc.). Furthermore, there will be actions available for doing things
like providing a WPS PIN for a station.

e653b62275 Add station table query to wpa_supplicant AP ctrl_iface
"wpa_cli all_sta" and "wpa_cli sta <addr>" can now be used to fetch
information about stations associated with the
wpa_supplicant-controlled AP.

ded30a6b41 Move STA list ctrl_iface handlers to a separate file

functionality with wpa_supplicant AP mode operations.

2678509dec WPS: Store device info and make it available through AP ctrl_iface
Store a copy of device attributes during WPS protocol run and make it
available for external programs via the control interface STA MIB
command for associated stations. This gives access to device name and
type which can be useful when showing user information about associated
stations.

52eb293dd2 WPS: Add support for AP reconfiguration with wps_reg
wpa_supplicant can now reconfigure the AP by acting as an External
Registrar with the wps_reg command. Previously, this was only used
to fetch the current AP settings, but now the wps_reg command has
optional arguments which can be used to provide the new AP
configuration. When the new parameters are set, the WPS protocol run
is allowed to continue through M8 to reconfigure the AP instead of
stopping at M7.

1ff733383f Delay processing of EAPOL frames when not associated
If an EAPOL frame is received while wpa_supplicant thinks the driver is
not associated, queue the frame for processing at the moment when the
association event is received. This is a workaround to a race condition
in receiving data frames and management events from the kernel.

The pending EAPOL frame will not be processed unless an association
event is received within 100 msec for the same BSSID.

This is a patch for OpenBSD wired IEEE 802.1X. This is only for wired,
not wireless, because OpenBSD uses wpa_supplicant only on wired now.

335ce76b1c nl80211: Use two sockets to avoid mixing command replies with events
Previously, both the command replies and unsolicited events were
received from the same socket. This could cause problems if an event

Using two sockets avoids this issue.

5cd89c26f9 Disable PMTU discovery for RADIUS packets (sent them without DF)
When Linux has Path MTU discovery enabled, it sets by default the DF bit
on all outgoing datagrams, also UDP ones. If a RADIUS message is bigger
than the smallest MTU size to the target, it will be discarded.

This effectively limits RADIUS messages to ~ 1500 Bytes, while they can
be up to 4k according to RFC2865. In practice, this can mean trouble
when doing EAP-TLS with many RADIUS attributes besides the EAP-Message.

ad469aecc1 Reject X.509 certificate strings with embedded NUL characters
These could, at least in theory, be used to generate unexpected common
name or subject alternative name matches should a CA sign strings with
NUL (C string termination) in them. For now, just reject the certificate
if an embedded NUL is detected. In theory, all the comparison routines
could be made to compare these strings as binary blobs (with additional
X.509 rules to handle some exceptions) and display NUL characters
somehow. Anyway, just rejecting the certificate will get rid of
potential problems with the C string getting terminated and it should
not really be used in certificates, so this should not break valid use
cases.

1ba787b954 Remove unneeded aes_i.h inclusion from number of places
The BLOCK_SIZE define can be made more specific by using AES_ prefix and
by moving it to aes.h. After this, most aes-*.c do not really need to
include anything from the internal aes_i.h header file. In other words,
aes_i.h can now be used only for the code that uses the internal AES
block operation implementation and none of the code that can use AES
implementation from an external library do not need to include this
header file.

108f9dd49b Fix crypto_cipher_init() EVP initialization
Better not specify EVP_CIPHER again for the second init call since that
will override key length with the default value. The previous version
was likely to work since most use cases would be likely to use the
default key length. Anyway, better make this handle variable length
ciphers (mainly, RC4), too, just in case it is needed in the future.

This is not really of that much use since rc4_skip() can be used as

76f04b38b0 Preliminary support for FIPS mode operation with OpenSSL
wpa_supplicant can now be built with FIPS capable OpenSSL for FIPS mode
operation. Currently, this is only enabling the FIPS mode in OpenSSL
without providing any higher level enforcement in wpa_supplicant.
Consequently, invalid configuration will fail during the authentication
run. Proper configuration (e.g., WPA2-Enterprise with EAP-TLS) allows
the connection to be completed.

It looks like GnuTLS does not know how to parse the previously used

On NetBSD 5.0, when I use wired 802.1X, "Invalid argument" occurs
on SIOCADDMULTI ioctl and 802.1X fails.

occurs on SIOCADDMULTI ioctl and 802.1X fails, too.
