6c9a98a20d IBSS RSN: Do not start multiple Auth/Supp for same peer
This avoids an issue when a received EAPOL-Key frame from a peer
is initiating IBSS RSN Authenticator and Supplicant for the peer
and the following new-STA-in-IBSS event from the driver is adding
yet another instance of Authenticator/Supplicant. The EAPOL-Key
RX case was already checking whether an instance had been started;
the driver new-STA event needs to do same.

50b05780c2 IBSS RSN: Delay setting of the initial TX GTK
The driver may get confused if we set the initial TX GTK before having
fully configured and connected to an IBSS, so better delay this
operation until the connection (join/start IBSS) has been completed.

449adbaca9 WPS: Indicate WPS-FAIL event on EAPOL timeout-based failure callback
If the EAPOL processing times out (e.g., if the AP stops replying
to messages for some reason) during WPS negotiation, we need to
indicate WPS-FAIL event from eapol_cb since no other WPS failure is
reported for this particular case.

c5cf0a18f1 WPS: Add mechanism for indicating non-standard WPS errors
Previously, only the Configuration Error values were indicated in
WPS-FAIL events. Since those values are defined in the specification
it is not feasible to extend them for indicating other errors. Add
a new error indication value that is internal to wpa_supplicant and
hostapd to allow other errors to be indicated.

Use the new mechanism to indicate if negotiation fails because of
WEP or TKIP-only configurations being disallows by WPS 2.0.

e24cf97c0d P2P: Check GO Neg Req retransmit limit in p2p_listen_end
This needs to be done both in the more normal location in
p2p_timeout_connect_listen() (internal timeout after driver event) and
in p2p_listen_end() as a workaround for the case where the driver event
is delayed to happen after the internal timeout.

8d806cc2af test-sha1: Add test vectors from RFC 6070
The test with very large iterations count is commented out since it
takes quite long to derive (it does pass, though). In addition, the
last test vector is commented out since pbkdf2_sha1() does not support
arbitrary binary passphrases (\0 inside the string).

0382097ef3 Use set_key addr to distinguish default and multicast keys
Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).

23763c6516 bsd: Fix receive buffer alignment issue
wpa_supplicant seems to crash from time to time on a NetBSD 4.0 MIPS
platform. The root cause turned out to be a MIPS alignment issue.

In my wpa_supplicant crash case, in function
wpa_driver_bsd_event_receive (from driver_bsd.c), the buf[2048] address
is started from i.e. 0x7fffd546, which is not 4 bytes aligned. Later
when it is casted to (struct if_msghdr *), and rtm->rtm_flags is used.
rtm->rtm_flags is "int" type, but its address is not 4 bytes aligned.
This is because the start address of rtm is not 4 bytes aligned.
Unfortunately in NetBSD MIPS kernel (unlike Linux MIPS kernel emulates
unaligned access in its exception handler), the default behavior is to
generate a memory fault to the application that accesses unaligned
memory address. Thus comes the early mentioned wpa_supplicant crash. An
interesting note is when I'm using the wpa_supplicant version 0.4.9, I
never saw this problem. Maybe the stack layout is different. But I
didn't look into details.

I used below patch to resolve this problem. Now it runs correctly for at
least several hours. But you might have a better fix (maybe we can use
malloc/free so that it is at least cache line aligned?). I'm also not
sure if other drivers should have the same problem.

f981eabcf0 WPS: Add option to disable open networks by default
CONFIG_WPS_REG_DISABLE_OPEN=y can be used to configure wpa_supplicant
to disable open networks by default when wps_reg command is used to
learn the current AP settings. When this is enabled, there will be a
WPS-OPEN-NETWORK ctrl_iface event and the user will need to explicitly
enable the network (e.g., with "select_network <id>") to connect to
the open network.

With the new kernel functionality coming to Linux to allow off-channel
TX, we can take advantage of that in the P2P code that currently uses
remain-on-channel. If a driver advertises support for it, it will be
asked to handle off-channel TX by itself.

0d7e5a3a29 Allow AP mode to disconnect STAs based on low ACK condition
The nl80211 driver can report low ACK condition (in fact it reports
complete loss right now only). Use that, along with a config option, to
disconnect stations when the data connection is not working properly,
e.g., due to the STA having went outside the range of the AP. This is
disabled by default and can be enabled with disassoc_low_ack=1 in
hostapd or wpa_supplicant configuration file.

d3e01b9d71 Re-initialize EAP ClientTimeout on for each session
ClientTimeout changes from EAP peer methods were not supposed to
change behavior for other EAP peer methods or even other sessions
of the same method. Re-initialize ClientTimeout whenever an EAP
peer method is initialized to avoid this. This addresses problems
where WPS (EAP-WSC) reduces the timeout and consecutive EAP runs
may fail due to too small timeout.

9dac8c3eaf P2P: Limit the retransmission of GO Negotiation request to 120
If the peer you want to connect to is no longer available (does not
acknowledge frames) when wpa_supplicant sends GO Negotition Request
frames, retransmission of this frame is done until the associated
p2p_device  structure is removed on timeout. In that case, no signal
is emitted to  inform the GO Negotiation has failed.

When sending an Invitation Request frame, the same retransmission
mechanism is in place but limit the transmission to 100 and hitting
the limit generates an event.

This patch adds the same mechanism as the one in place for Invitation
Request, but with limit of 120 to match the existing wait_count for
for GO Negotiation.

cc5e390d28 WPS: Require PBC match with wps_pbc that specifies BSSID
The WPS mode was already verified when the AP was configured for
WPA/WPA2, but this was not done with AP that was in open mode.
Fix this by allowing wpa_supplicant_ssid_bss_match() to be called
in non-WPA configuration, too. With this change, wps_pbc BSSID
command will wait until the specified target AP is in active PBC
mode before trying to connect to it.
