9b7a1bd7ed Option to reduce Probe Response frame responses during max STA
The new hostapd configuration parameter no_probe_resp_if_max_sta=1 can
be used to request hostapd not to reply to broadcast Probe Request
frames from unassociated STA if there is no room for additional stations
(max_num_sta). This can be used to discourage a STA from trying to
associate with this AP if the association would be rejected due to
maximum STA limit.

ca33a5e895 Add "git describe" based version string postfix
If hostapd or wpa_supplicant is built from a git repository, add a
VERSION_STR postfix from the current git branch state. This is from "git
describe --dirty=+". VERSION_STR will thus look something like
"2.6-devel-hostap_2_5-132-g4363c0d+" for development builds from a
modified repository.

This behavior is enabled automatically if a build within git repository
is detected (based on ../.git existing). This can be disabled with
CONFIG_NO_GITVER=y in wpa_supplicant/.config and hostapd/.config.

932267ad67 P2P: Add P2P_ASSOC_RESP to P2P vendor elements
Vendor specific IEs added to frame type P2P_ASSOC_RESP are saved in
the interface context, but as they are added as part of the P2P IEs,
they need to be saved in the global P2P context.

Fix this by directing vendor specific IEs added to P2P_ASSOC_RESP
frame type to the P2P context.

cf0dffd67e tests: Change wpas_config_file test for dedicated P2P Device case
SAVE_CONFIG command on the global control interface tries to save
the config file on all interfaces. The test disabled updating the
config file only on one interface, thus for configurations that
support a dedicated P2P Device interface, saving the config file
would still have succeeded on the P2P Device interface.

Fix the test by disabling updating the configuration file on the global
control interface (which will, in practice, disable this for the P2P
Device interface) in addition to disabling it on the main interface.

2b12b3602a P2P: Do not reply to GO Negotiation Request if peer is waiting for us
This improves robustness of GO Negotiation in special cases where GO
Negotiation Request frames from the peer may end up getting delivered
multiple times, e.g., due to interference and retransmitted frames not
getting properly filtered out in duplicate detection (which is something
that number of drivers do not implement for pre-associated state).

If we have already replied with GO Negotiation Response frame with
Status 1 (not yet ready), do not reply to another GO Negotiation Request
frame from the peer if we have already received authorization from the
user (P2P_CONNECT command) for group formation and have sent out our GO
Negotiation Request frame. This avoids a possible sequence where two
independent GO Negotiation instances could go through in parallel if the
MAC address based rule on avoiding duplicate negotiations is not able to
prevent the case. This can allow GO Negotiation to complete successfully
whereas the previous behavior would have likely resulted in a failure
with neither device sending a GO Negotiation Confirm frame.

e8dc205f17 nl80211: Disable 11b rates for P2P (additional cases)

207976f053 Fix Suite B 192-bit AKM to use proper PMK length
In addition to the PTK length increasing, the length of the PMK was
increased (from 256 to 384 bits) for the 00-0f-ac:12 AKM. This part was
missing from the initial implementation and a fixed length (256-bit) PMK
was used for all AKMs.

Fix this by adding more complete support for variable length PMK and use
384 bits from MSK instead of 256 bits when using this AKM. This is not
backwards compatible with the earlier implementations.

ae7d9fbd3d Remove unreachable PMKSA cache entry addition on Access-Accept
The previous implementation used an obsolete sm->eapol_key_crypt pointer
which was not set anywhere (i.e., was always NULL). In addition, the
condition of sm->eap_if->eapKeyAvailable was not valid here since this
is the case of MSK from an external authentication server and not the
internal EAP server. Consequently, the wpa_auth_pmksa_add() call here
was never used.

The PMKSA cache was still added, but it happened at the completion of
the 4-way handshake rather than at the completion of EAP authentication.
That later location looks better, so delete the unreachable code in
Access-Accept handling. In addition, remove the now complete unused
struct eapol_state_machine eapol_key_* variables.

cd571e14dd P2PS: Fix persistent group reporting in wpas_p2ps_prov_complete()
When one peer doesn't include a persistent group info in PD Request
the other peer shouldn't report a persistent group usage with this
peer even if such a persistent group exists locally. This condition
could be violated in the previous implementation.

In case a local persistent group exists and the
wpas_p2ps_prov_complete() function is called with persist_ssid parameter
set to NULL, wpa_supplicant reported P2PS-PROV-DONE with persist=<idx>
instead of conncap=<role> parameter.

This happened because the wpas_p2p_get_persistent() function was called
without verification whether the persist_ssid was set to NULL. In this
case the wpas_p2p_get_persistent() returns the first existing persistent
group matching the P2P Device Address without verifying the group's
SSID. After that the group ID is used as persist=<idx> parameter of
P2PS-PROV-DONE event.

Fix the issue by adding persist_ssid and persist_ssid_size verification
as a condition for the wpas_p2p_get_persistent() call.

ebd32943cb P2PS: Add channel policy to PD Request
Add operating channel selection and channel list processing similar to

without being previously aware of the current constraints, i.e., the
channels currently in use by other interfaces. To handle this, extend
the get_group_capability() callback to also handle channel selection
aspects of group capabilities.

PD, force its current operating frequency in the PD attributes.
