* wpa_supplicant - Internal definitions
Add suspend/resume notifications wpa_supplicant can now be notified of suspend/resume events, e.g., from pm-action scripts. This allows wpa_supplicant to clear information that may become invalid during a suspend operation.

Add BSS table to track scan results without dropping information Collect information from scan results into a BSS table that will not expire information as quickly as scan results where every new scan, no matter for how limited set of channels/SSIDs, clears all old information. For now, this is only used for D-Bus BSS added/removed notifications, but this will likely be extended to be used internally instead of the scan results to better support partial scans.

Add preliminary hostapd data structure initialization for AP mode wpa_supplicant can now initialize hostapd data structures when mode=2 is used to set up an AP. The hostapd configuration is not yet set based on wpa_supplicant network configuration block. In addition, the glue code for hostapd driver_ops needs number of functions that will be needed for AP functionality.

P2P: Update D-Bus network object semantics during group formation Do not emit network objects during P2P group formation since such network objects can confuse certain apps. Instead, a persistent group object is created to allow apps to keep track of persistent groups. Persistent group objects only represent the info needed to recreate the group. Also fixes a minor bug in the handling of persistent group objects during WPS operations. Signed-off-by: Jayant Sane <jayant.sane@intel.com>

Added initial step for IBSS RSN support This commit adds a new build option, CONFIG_IBSS_RSN=y, that can be used to enable RSN support for IBSS. This links in RSN Authenticator code from hostapd and adds code for managing per-peer information for IBSS. A new wpa_cli command or driver event can be used to request RSN authentication with an IBSS peer. New RSN Authenticator and Supplicant will be allocated for each peer. The basic state machine setup code is included in this commit, but the state machines are not properly started yet. In addition, some of the callback functions are not yet complete.

dbus: Share common initialization code for both old and new interface This was mostly identical code that had been copied for the new D-Bus API implementation and as such, should really have been shared from the beginning. In addition, the copied code ended up generating interesting stack traces since the actual D-Bus connection was being shared even though the pointer to it was stored in two distinct data structures. The old D-Bus code ended up dispatching some D-Bus callbacks which ended up running the new D-Bus code. Since the private context pointers were mostly identical, everything seemed to more or less work, but this design was just making things more complex and potentially very easy to break.

DBus: Add ability to report probe requests Some applications require knowing about probe requests to identify devices. This can be the case in AP mode to see the devices before they connect, or even in P2P mode when operating as a P2P device to identify non-P2P peers (P2P peers are identified via PeerFound signals). As there are typically a lot of probe requests, require that an interested application subscribes to this signal so the bus isn't always flooded with these notifications. The notifications in DBus are then unicast only to that application. A small test script is also included. Signed-hostap: Johannes Berg <johannes.berg@intel.com>

Added an optional mitigation mechanism for certain attacks against TKIP by delaying Michael MIC error reports by a random amount of time between 0 and 60 seconds if multiple Michael MIC failures are detected with the same PTK (i.e., the Authenticator does not rekey PTK on first failure report). This is disabled by default and can be enabled with a build option CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config. This may help in making a chopchop attack take much longer time by forcing the attacker to wait 60 seconds before knowing whether a modified frame resulted in a MIC failure.

Add preliminary background scan and roaming module design This allows background scanning and roaming decisions to be contained in a single place based on a defined set of notification events which will hopefully make it easier to experiment with roaming improvements. In addition, this allows multiple intra-ESS roaming policies to be used (each network configuration block can configure its own bgscan module). The beacon loss and signal strength notifications are implemented for the bgscan API, but the actual events are not yet available from the driver. The included sample bgscan module ("simple") is an example of what can be done with the new bgscan mechanism. It requests periodic background scans when the device remains associated with an ESS and has couple of notes on what a more advanced bgscan module could do to optimize background scanning and roaming. The periodic scans will cause the scan result handler to pick a better AP if one becomes available. This bgscan module can be taken into use by adding bgscan="simple" (or bgscan="simple:<bgscan interval in seconds>") into the network configuration block.

P2P: Allow multiple scan runs to find GO for p2p_connect join If the GO is not found, we cannot send Provisioning Discovery Request frame and cannot really connect anyway. Since the Provisioning Discovery is a mandatory part, it is better to continue join-scan until the GO is found instead of moving to the next step where normal connection scan is used (PD would not be used from there). Use a limit of 10 scan attempts for p2p_connect join to avoid getting in infinite loop trying to join. If the GO is not found with those scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the join attempt.

Add preliminary background scan and roaming module design This allows background scanning and roaming decisions to be contained in a single place based on a defined set of notification events which will hopefully make it easier to experiment with roaming improvements. In addition, this allows multiple intra-ESS roaming policies to be used (each network configuration block can configure its own bgscan module). The beacon loss and signal strength notifications are implemented for the bgscan API, but the actual events are not yet available from the driver. The included sample bgscan module ("simple") is an example of what can be done with the new bgscan mechanism. It requests periodic background scans when the device remains associated with an ESS and has couple of notes on what a more advanced bgscan module could do to optimize background scanning and roaming. The periodic scans will cause the scan result handler to pick a better AP if one becomes available. This bgscan module can be taken into use by adding bgscan="simple" (or bgscan="simple:<bgscan interval in seconds>") into the network configuration block.

Extend load balancing optimization in BSS blacklisting Move the previously SME specific optimization code into generic function that can be used from non-SME code, too, and use it to handle disconnection events. In other words, allow disconnection event to trigger similar optimized scanning case to handle a common load balancing mechanism. If there is another BSS in the same ESS when we receive a disconnection event, scan only the known frequencies of such other BSSes on the next attempt to speed up recovery.

Support driver-based BSS selection in ap_scan=1 mode If the driver indicates that it supports BSS selection (including roaming within an ESS) with WPA_DRIVER_FLAGS_BSS_SELECTION, modify ap_scan=1 mode to behave like ap_scan=2 mode for BSS selection. The initial scan is still done to avoid the need for strict configuration of or security parameters (e.g., to figure out whether TKIP or CCMP is being used as the group cipher). However, when requesting the driver to connect, the bssid and freq parameters are not provided to leave the driver in control of selecting which BSS to use and to allow the driver to decide when to roam.

Add handling of OBSS scan requests and 20/40 BSS coex reports Add support for HT STA to report 40 MHz intolerance to the associated AP. A HT station generates a report (20/40 BSS coexistence) of channel list if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz transmission (i.e., 40 MHz intolerant bit is set in HT capabilities IE) from the scan results. Parse the OBSS scan parameter from Beacon or Probe Response frames and schedule periodic scan to generate 20/40 coexistence channel report if requested to do so. This patch decodes Scan Interval alone from the OBSS Scan Parameters element and triggers scan on timeout.

Fix D-Bus build without ctrl_iface Commit 7de5688d682d4a96a4ce1f7959428a0112d4b75f started using wpa_supplicant_ctrl_iface_ctrl_rsp_handle() from the D-Bus code, but left this function in ctrl_iface.c that is included conditionally. Fix this by moving the common function into wpa_supplicant.c so that it can be included for builds that include only either ctrl_iface or D-Bus.

P2P: Update D-Bus network object semantics during group formation Do not emit network objects during P2P group formation since such network objects can confuse certain apps. Instead, a persistent group object is created to allow apps to keep track of persistent groups. Persistent group objects only represent the info needed to recreate the group. Also fixes a minor bug in the handling of persistent group objects during WPS operations. Signed-off-by: Jayant Sane <jayant.sane@intel.com>
