Allow another EAP method to be tried if one of the enabled methods
fails. If all the remaining methods fail, reject connection by adding a
new METHOD_REQUEST -> FAILURE transition. Previously, this case resulted
in the state machine trying to send a message when none was available
and then waiting for a following event until timeout.

It is possible for the authentication server to be configured with a
PKCS #12 file that includes a private key, a server certificate, and a
CA certificate. This combination could result in server_cert and ca_cert
parameters not being present and that should still result in TLS context
getting initialized.
Signed-hostap: Jouni Malinen <j@w1.fi>
It was possible to configure hostapd in a way that could try to
initialize a TLS-based EAP method even when TLS library context was not
initialized (e.g., due to not configuring server or CA certificate).
Such a case could potentially result in NULL pointer dereference in the
TLS library, so check for this condition and reject EAP method
initialization.

Commit 390e489c0d extended hostapd BSS
interface removal capabilities. However, it ended up causing a
regression in wpa_supplicant P2P group interface handling. That P2P
group interface is removed through another driver_nl80211.c BSS context
and as such, the bss->added_if is not set. Fix this by verifying whether
the request is for another ifindex and if so, removing the interface
even if added_if is not marked.

An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

Some non-mac80211 drivers, such as ath6kl, support STA inactivity timer
in firmware and may not provide connected stations' idle time to the
userspace. If the driver indicates support for offloaded operation, do
not start the inactivity timer in the hostapd.

On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).
If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.
This patch fixes this issue by restoring the previous scan_req value.

A reenable of the TDLS link while the host driver is already processing
the same (due to the retransmitted M2/M3 frames) might result in a

Thus, issue enable link only when the peer's TDLS status signifies no

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

The shorter 250 ms wait for the next scan request can be used also for

Some devices disable use of U-NII-1 (channels 36-48) for P2P due to it
being indoor use only in number of locations. If U-NII-3 (channels

Only force_freq was used in the wpas_p2p_set_own_freq_preference() call
which allowed the P2P module channel re-selection to ignore the
preference for using a channel we are already using. Fix this by setting
either force_freq or pref_freq as the preference based on which one is
set. This allows p2p_ignore_shared_freq parameter to be used whether to
prefer the shared frequency in this case.

There is no need to use wpas_p2p_num_unused_channels() here in the

p2p_ignore_shared_freq=1 was supposed to allow a MCC-capable device to
ignore a preference for using the same channel on multiple interfaces.
However, it was not used when inviting a peer to re-invoke a persistent
group. This case needs special handling since the peer's channel list is
not available to perform channel reselection and the operating channel
indicated in the Invitation Request frames ends up getting used as the
operating channel if the transmitted of that frames becomes the GO.

wpas_p2p_setup_freqs() design to use number of MCC channels capability
from the driver. However, it resulted in regression on how the preferred

force_freq was set unconditionally even though this was supposed to be
done only if no additional channels are available. pref_freq needs to be
used when possible to avoid preventing connection.
