This patch notifies the upper framework that an on-going discovery has
been stopped. This is useful in cases where a p2p_find with a timeout
value initiated by the upper framework has been finished or when the
framework initiated "p2p_find" is stopped by a "p2p_connect".

Some deployed station implementations seem to send msg 4/4 with
incorrect type value in WPA2 mode. Add a workaround to ignore that issue
so that such stations can interoperate with hostapd authenticator. The
validation checks were added in commit

Some supplicant implementations (e.g., Windows XP WZC) update SNonce for
each EAPOL-Key 2/4. This breaks the workaround on accepting any of the
pending requests, so allow the SNonce to be updated even if we have
already sent out EAPOL-Key 3/4.
While the issue was made less likely to occur when the retransmit
timeout for the initial EAPOL-Key msg 1/4 was increased to 1000 ms,
this fixes the problem even if that timeout is not long enough.

Now that we can use driver_nl80211.c with non-mac80211 drivers that
implement SME/MLME internally, we may not get inactivity time from the
driver. If that is the case, we need to skip disconnection based on
maximum inactivity timeout. This fixes some unexpected disconnection
cases with ath6kl in AP mode.
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.
Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.

Commit e9c3c1afed added a new D-Bus
method and that was enough to push the Introspect XML buffer over
the previously allocated 8000 bytes. Increase the buffer size to
make enough room for P2P interface. In addition, add a debug
message to indicate if an XML segment does not fit into the buffer
to make this types of failures somewhat easier to catch.

IEEE Std 802.1X-2004 does not clear authWhile and heldWhile in this
case, but doing so allows the timer tick to be stopped more quickly when
the port is not enabled. Since these variables are used only within HELD
and RECEIVE states, clearing them on initialization does not change
actual state machine behavior. This reduces some unnecessary operations
in port disabled state and cleans up the wpa_supplicant debug log after
disconnection.

already been known to have failed. The event at that point can be

The offchanok parameter is hardcoded to one in number of paths and that
added NL80211_ATTR_OFFCHANNEL_TX_OK attribute to NL80211_CMD_FRAME
unconditional. cfg80211 rejects this with EINVAL if the driver does not
indicate support for offchannel TX. Fix this by not requesting
offchannel TX depending on driver capabilities. Remain-on-channel
operation was used for those cases anyway, so the additional attribute
was not really needed for these in the first place.

When nl80211_setup_ap() has enabled Probe Request reporting, this must
not be disabled when P2P Listen state is stopped to avoid breaking AP
mode operations. This could happen, e.g., if a Probe Request frame was
received from a P2P device that the we are trying to invite to our group
(i.e., when operating in GO role). p2p_probe_req_rx() calls
p2p_invite_start() in this case and that ends up calling
p2p->cfg->stop_listen() which calls probe_req_report() driver op.

hostapd uses the poll method to check if the station is alive
after the station has been inactive for ap_max_inactivity seconds.
Make the poll mechanism configurable so that user can choose to
disconnect idle clients.
This can be especially useful when some devices/firmwares have
restrictions on the number of clients that can connect to the AP
and that limit is smaller than the total number of stations trying
to use the AP.

The 100 ms timeout on retransmitting group key message can be too short
for stations that are in power save mode or if there is a large number

should allow this to be recovered from, it is useful to avoid
unnecessary frames to save soem CPU and power.

Add a new persistent group network block field, p2p_client_list, to

The P2P module provides access to public peer data in struct
p2p_peer_info. Use this to build the P2P_PEER information in
ctrl_iface.c instead of providing such text format data from the P2P
module.
The internal data that was previously built in p2p_get_peer_info() as
part of the text format peer data is now available through a separate
p2p_get_peer_info_txt() function. This is still included in P2P_PEER
output to maintain backwards compatibility with external programs that
could have started to use this. However, it should be noted that this
data is not really supposed to be used for anything else apart from
debugging purposes and its format is subject to change.

If the driver was associated in station mode just before the AP mode was

If p2p_listen is issued during a p2p_scan, a pending after-scan operation

The p2p_group_idle configuration parameter is much more useful for
GO role, so use a separate hardcoded value of 10 seconds in P2P
client role. In practice, this means that the P2P client role will
automatically tear down the group when the GO tears down the group.
The 10 second timeout is enough to recover from temporary disconnections
without unnecessary tearing down the group if the GO is still present
