If p2p_listen is called while previous listen command's
remain_on_channel event is pending, the p2p_listen would fail
and it used to clear pending_listen_freq. Now when the remain-
on-channel event comes from the driver, the pending_listen_freq
doesn't match and gets ignored. This was leading to a case
where listen state was getting stuck (in case of WAIT_PEER_CONNECT
state).

This patch adds epoll option for the eloop implementation. This can be
selected with the CONFIG_ELOOP_EPOLL=y build option.
[merit]
See Table1.
Table1. comparison table
+--------+--------+-----------+------------+-------------+
| | add fd | remove fd | prepare fd | dispatch fd |
+--------+--------+-----------+------------+-------------+
| select | O(1) | O(1) | O(N) | O(N) |
+--------+--------+-----------+------------+-------------+
| poll | O(1) | O(1) | O(N) | O(N) |
+--------+--------+-----------+------------+-------------+
| epoll | O(1) | O(1) | 0 | O(M) |
+--------+--------+-----------+------------+-------------+
"add fd" is addition of fd by eloop_sock_table_add_sock().
"remove fd" is removal of fd by eloop_sock_table_remove_sock().
"prepare fd" is preparation of fds before wait in eloop_run().
"dispatch fd" is dispatchment of fds by eloop_sock_table_dispatch().
"N" is all watching fds.
"M" is fds which could be dispatched after waiting.
As shown in Table1, epoll option has better performance on "prepare fd" column.
Because select/poll option requires setting fds before every select()/poll().
But epoll_wait() doesn't need it.
And epoll option has also better performance on "dispatch fd" column.
Because select/poll option needs to check all registered fds to find out
dispatchable fds. But epoll option doesn't require checking all registered fds.
Because epoll_wait() returns dispatchable fd set.
So epoll option is effective for GO/AP functionality.
[demerit]
The epoll option requires additional heap memory. In case of P2P GO, it is
about 8K bytes.

p2p_get_pref_freq() went through the full list only if the channels
arguments was provided. If no channel list contraint was in place, the
first pref_chan item was picked regardless of whether it is valid
channel and as such, a later valid entry could have been ignored. Allow
this to loop through all the entries until a valid channel is found or
the end of the pref_chan list is reached. As an extra bonus, this

Before starting a 20/40 MHz BSS on the 2.4 GHz band, a 40-MHz-capable HT
AP is required by the rules defined in IEEE Std 802.11-2012 10.15.5 to
examine the channels of the current operational regulatory domain to
determine whether the operation of a 20/40 MHz BSS might unfairly
interfere with the operation of existing 20 MHz BSSs. The AP (or some of
its associated HT STAs) is required to scan all of the channels of the
current regulatory domain in order to ascertain the operating channels
of any existing 20 MHz BSSs and 20/40 MHz BSSs. (IEEE 802.11-2012 S.5.2

Peer should handle a GO Negotiation exchange correctly when the
responding device does not have WSC credentials available at the
time of receiving the GO Negotiation Request. WSC Credentials
(e.g., Pushbutton) can be entered within the 120 second timeout.
Presently, if concurrent session is not active, the peer would wait for
GO Negotiation Request frame from the other device for approximately one
minute due to the earlier optimization change in commit
a2d6365760. To meet the two minute
requirement, replace this design based on number of iterations with a
more appropriate wait for the required number of seconds.

bss->freq was not updated for IBSS, so whatever old value was stored

Some OpenSSL versions have vulnerability in TLS heartbeat request
processing. Check the processed message to determine if the attack has
been used and if so, do not send the response to the peer. This does not
prevent the buffer read overflow within OpenSSL, but this prevents the

This change is an additional layer of protection if some yet to be
identified paths were to expose this OpenSSL vulnerability. However, the
way OpenSSL is used for EAP-TLS/TTLS/PEAP/FAST in hostapd/wpa_supplicant
