fb660a9431 Do not double free cfg struct if netlink_init() fails
If netlink_init() fails on socket create or bind the cfg struct
provided as parameter is freed by netlink_init(). Callers of
netlink_init() also free this struct on their error paths leading
to double free.

The NL80211_CMD_TDLS_OPER command can be used as an event based on a

a8c5b43ad3 nl80211: Roam correctly through cfg80211 without SME
Change the nl80211 driver in wpa_supplicant to correctly handle
connecting to a new AP through cfg80211 without SME capability. As
before, the driver will disconnect from the previously associated AP,
but now we attempt to immediately connect to our intended AP. This
prevents us from blacklisting the AP we were trying to connect to
because of a semantic mismatch between cfg80211 and wpa_supplicant. The
disconnect/connect patch generates a local disconnect nl80211 event
which we discard because we're already correctly tracking the pending
association request.

In detail:

cfg80211 does not support connecting to a new BSS while already
connected to another BSS, if the underlying driver doesn't support
separate authenticate and associate commands. wpa_supplicant is written
to expect that this is a supported operation, except for a little error
handling that disconnects from the current BSS when roaming fails and
relies on autoconnect logic to reconnect later. However, this failure to
connect is incorrectly attributed to the new AP we attempted to
associate with, rather than a local condition in cfg80211.

The combined effect of these two conditions is that full-mac drivers
accessible through cfg80211 but without SME capability take a long time
to roam across BSS's because wpa_supplicant will:
1) Fail to associate for local reasons
2) Disconnect and return that the association request failed
3) Blacklist the association target (incorrectly)
4) Do a scan
5) Pick a less desirable AP to associate with

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

23c84252a4 P2P: Add option to force SSID/passphrase for GO Negotiation
An existing persistent group information can now be used to force GO
Negotiation to use the previously used SSID/passphrase from a persistent
group if we become a GO. This can be used as an alternative to inviting
a new P2P peer to join the group (i.e., use GO Negotiation with GO
intent 15 instead of starting an autonomous GO and using invitation),
e.g., in case a GO Negotiation Request is received from a peer while we
are not running as a GO. The persistent group to use for parameters is
indicated with persistent=<network id> parameter to p2p_connect.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe

e32ad281ca nl80211: Register for Beacon frames in AP mode
When running AP mode, we need to receive beacons over overlapping BSSes
to handle protection. Use the new nl80211 command for this. As the
command works per wiphy (and we don't want to receive the Beacon frames
multiple times) add an abstraction that keeps track of per-wiphy data.

a11241fa11 nl80211: Use nl80211 for mgmt TX/RX in AP mode
To achieve this, multiple things are needed:
 1) since hostapd needs to handle *all* action frames,
    make the normal registration only when in a non-AP
    mode, to be able to do this use the new socket
 2) store the frequency in each BSS to be able to give
    the right frequency to nl80211's mgmt-tx operation
 3) make TX status processing reject non-matched cookie
    only in non-AP mode

The whole thing depends on having station-poll support
in the kernel. That's currently a good indicator since
the kernel patches are added together.

To recover from this quickly, run a single channel scan to get the

mac80211_hwsim has now obsoled the need for this type of testing.

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.

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.

f67eeb5c32 nl80211: fix interface address assignment
When a new interface is created and already has a separate MAC address
assigned by the kernel, then we need to use that address, not just when
we've created a locally administered address.

This fixes use_p2p_group_interface=1 for iwlagn as it already makes
mac80211 assign an address for a second interface since the hardware has
two addresses assigned.

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.

871f4dd069 Allow driver wrappers to indicate whether result codes are sane
Some drivers are not providing exactly reliable error codes (e.g.,
with WEXT), but others may actually indicate reliable information.
Allow driver wrappers to indicate if that is the case and use
optimizations if so. For now, this improves nl80211 with
NL80211_CMD_CONNECT for a case where connection request fails.

c55f774d00 nl80211: Add preliminary code for testing separate P2P group interface
driver_param=use_p2p_group_interface=1 can now be used to test
nl80211-drivers with separate P2P group interface. In other words,
the main interface (e.g., wlan0) is reserved for P2P management
operations and non-P2P connections and a new group interface (e.g.,
p2p-wlan0-0) is created for the P2P group.

This implementation is very minimal, i.e., it only support address
allocation for a single P2P group interface (if the driver does not
handle this internally). In addition, not all functionality has yet
been tested, so for now, this is disabled by default and needs that
special driver_param to enable.

This is otherwise identical to

non-P2P connections makes some operations differ.

The driver wrapper may now indicate the preferred channel (e.g., based
on scan results) on both 2.4 GHz and 5 GHz bands (and an overall best
frequency). When setting up a GO, this preference information is used
to select the operating channel if configuration does not include
hardcoded channel. Similarly, this information can be used during
GO Negotiation to indicate preference for a specific channel based
on current channel conditions.

p2p_group_add command can now use special values (freq=2 and freq=5)
to indicate that the GO is to be started on the specified band.

Pass data frames from unknown STAs to hostapd in order to reply with
a Deauthentication or Disassociation frame. This fixes compliance
with IEEE Std 802.11-2007, 11.3.

Furthermore, this does not cause a lot of overhead (at least with
mac80211 drivers) since mac80211 does not pass all data frames (but
at least from unauthenticated and unassociated STAs) to cooked monitor
interfaces.

available).

32f4e7b124 wext: Fix scan result signal levels when driver reports in dBm
wpa_supplicant showed signal levels incorrectly with some drivers:
Jun  6 16:29:36 rupert wpa_supplicant[18945]: Current BSS: 00:0d:97:11:40:d6
level=190
Jun  6 16:29:36 rupert wpa_supplicant[18945]: Selected BSS: 00:0d:97:11:50:09
level=192

Judging from output from other tools (iwlist) and the min_diff block
at the end of wpa_supplicant_need_to_roam, it seems these values
should actually be negative. Specifically, if one treats that number
as a signed char instead of unsigned, everything matches up.

To be honest, I've little to no understanding of wireless, but looking
at the source code for wireless-tools (iw_print_stats in iwlib.c), it
seems that the fields of the iw_quality struct need to be decoded
differently depending on various flags. I guess
src/drivers/driver_wext.c should have similar logic in
wext_get_scan_qual.

I wrote a patch that attempts to replicate some of that logic,
although it may be more complicated than is necessary; I think some of
the complexity is for backwards-compatibility, which might not be
necessary depending on wpa_supplicant's dependencies? In any case, it
is attached. Again, I don't know how any of this works, so it's likely
the patch is a bit off. But I think at least the logic to determine
min_diff in wpa_supplicant_need_to_roam would be more accurate if
level were determined correctly.

cb30b297bd nl80211: Ignore "DEAUTH" messages from APs we are not associated to
DEAUTH messages can come from a number of different sources. The one
that's hurting us currently is DEAUTH netlink messages coming to us
from compat-wireless in response to local_state_change DEAUTH messages
we sent as a part of cleaning up state in driver_nl80211's
clear_state_mismatch() function. However, DEAUTH messages can come
from a variety of unwanted sources, including directed denial-of-service
attacks (although MAC verification doesn't place that high a barrier),
so this validation is actually generically useful, I think.

The downside to this method is that without a kernel based approach
"iw dev wlan0 link" no longer works correctly after clear_state_mismatch()
is done.  This will be pursued with the kernel folks.
