Remove the separate driver_ops functions set_cts_protect(),
set_preamble(), set_short_slot_time(), and set_ht_params(). These
belong into same set of operations as set_ap(), so there is no need
to maintain separate functions that just make the driver wrapper
more complex.
Since these have only been used with driver_nl80211.c, the driver_ops
can be removed immediately instead of maintaining backwards
compatibility period with the old functions.
The AP client isolation parameter is now available through set_ap().
driver_nl80211.c was the only driver wrapper using the set_intra_bss()
call in hostap.git, but some external trees may have used this. Once
those are cleared, the set_infra_bss() driver_ops can be removed
completely. The only remaining use case for it currently is in P2P
GO mode with wpa_supplicant.
AP mode operations were used for P2P device discovery Listen state
only during early experiments. This has now been cleaned up and
ieee802_11_set_beacon() is not called for P2P device discovery.
As such, this hack to skip Beacon configuration can be removed.
This is the first step in allowing SA Query mechanism in hostapd to be
used with drivers that implement authentication and association MLME/SME
(i.e., do not use ieee802_11.c).
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.
"hostapd_cli ess_disassoc (STA addr) (URL)" can now be used to send
an ESS Dissassociation Imminent notification to the STA. This event
is shown in wpa_supplicant ctrl_iface monitors (e.g., wpa_cli):
"WNM: ESS Disassociation Imminent - session_info_url=http://example.com/session/"
The new wpa_supplicant.conf file global parameters interworking and
hessid can be used to configure wpa_supplicant to include
Interworking element in Probe Request frames.
Commit 17f6b90056 moved the concatenation
of WPS IEs, but did not include the validation that the IE buffer is not
NULL. In addition, the concatenation needs to be done based on the full
IE buffer instead of the parsed pointer that includes only a single
WPS IE.
The base64 encoded data cannot included pad characters in the middle, so
we can stop the loop at the first sequence of pad characters. If the
sequence includes more than two pad characters, the encoding is invalid
and we can indicate failure.
Use the SSID filter list passed in the scheduled scan request down to
the kernel driver, so it can use the list to return only the wanted
SSIDs. Some kernel drivers can use this information to offload the
SSID filter to the hardware, helping with reducing the power
consumption.

Pass SSIDs to be matched in scheduled scan results. Only the SSIDs
that are included in the match lists will be reported by the driver,
so the filtering can be offloaded to the hardware and the power
consumption can be reduced.

With scheduled scan support, we may need to pass more than 10 SSIDs in
a single scan request. Some drivers (e.g., wl12xx) support up to 16
SSIDs at once.
Change WPAS_MAX_SCAN_SSIDS from 10 to 16.

In new Linux kernel versions (>=3.0), nl80211 adds scheduled scan
capability. In order to use this feature to its full extent, we need
to support it in the wpa_supplicant core, so that it can also be used
by other drivers.
This commit adds initial scheduled scan support operations and events.

Commit 19ec1f262e tried to fix some
cases for history prev selection, but it broke others. Fix this
properly by using a separate entry for the current edit line that
is not yet in history buffer.
Currently the P2P Interface name[p2p-%s-%d] is reset when the P2P
Interface name reaches the "IFNAMSIZ" limit. Monitor interface name is
derived from p2p interface name with the addition of few characters
[mon.p2p-%s-%d] and hence Monitor interface name hits IFNAMSIZ limit
before P2P Interface name. Rename the monitor interface name to
mon-%s-%d to reduce the length to same with p2p-%s-%d.
Data path for stations that get successfully associated to the
hostapd but fail to get added in the driver/firmware, will not
work. In such cases, hostapd should deauth and disconnect such
stations. In such scenario, hostapd should disconnect the STAs.

The password_hash parameter was not copied in case of the integrated
authentication server (but was for RADIUS server). This broke EAP
authentication when the user entry used NT-hash.
This currently unused function would have triggered wpabuf overflows
due to incorrect variable being reset to zero in the case the old
NoA wpabuf was large enough for the new data.
The EAPOL authenticator was previously forcing disconnection in the WPS
use case. However, this can be benefitial operation with any IEEE 802.1X
authentication mechanism and need not be limited to WPS. This helps some
use cases like EAP-FAST where provisioning may require two
authentication runs if the authentication server does not allow the PAC
provisioning step to be used for normal data connection. While the
station would be free to decide to re-associate in such a case, not all
stations do and as such, it helps if the AP does that instead of leaving
the association up with EAPOL state machine in HELD state for 60
seconds.
While EAP-FAST uses protected success notification, RFC 5422, Section
3.5 points out a possibility of EAP-Failure being sent out even after
protected success notification in case of provisioning. Change the
EAP-FAST peer implementation to accept that exception to the protected
success notification. This allows the station to re-connect more quickly
to complete EAP-FAST connection in the case the server rejects the
initial attempt by only allowing it to use to provision a new PAC.
If GO Negotiation Request (or in theory, also GO Negotiation Response)
frame is delivered multiple time for processing, the SSID of the group
could end up getting changed. This could result in possible issues if
the peer ended up using different SSID. To avoid this, make sure the
SSID does not get changed unless the negotiation is for a new group.
Whenever PMK gets changed (e.g., due to re-authentication), all PMKSA
caching entries that were created using the previous PMK needs to be
replaced. Previously, only the entry for the current AP was cleared.
Flush the other entries based on network_ctx matches to get rid of the
OKC entries. These entries can then be re-creating using OKC with the
new PMK.
When polling a station that has been inactive for a while, hostapd currently
always uses a null data frame. This is a bit strange with uAPSD clients
(though it seems to mostly work) since the EOSP bit can never be set in a
non-QoS frame. Make hostapd use QoS null data frames for probing when the
station is a QoS STA.
