Instead of silently dropping the response that requires fragmentation,
send an error response to the station to make it aware that no full
response will be available.

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).

Follow the PKCS #1 v1.5, 8.1 constraint of at least eight octets long PS

Incorrect password was already tested with TTLS/MSCHAPv2, but the other
non-EAP inner methods in TTLS use their own implementation of password
validation, so check each and also verify the case of no matching EAP
user entry for the specific method.

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
simplifies the p2p_get_pref_freq() implementation quite a bit.

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
Establishing a 20/40 MHz BSS).
Add the check for an overlapping 20 MHz BSS to the initial AP scan for
the P == OT_i case in 10.15.3.2.

scard_gsm_auth() used SIM_CMD_GET_RESPONSE for both SIM and USIM. Convert
the command into USIM_CMD_GET_RESPONSE for USIM.
Since commit eb32460029 ("Fix switching from EAP-SIM to EAP-AKA/AKA'")
EAP-SIM is using the USIM if available. This triggers a probably ancient
bug in scard_gsm_auth(), which results in sending the wrong get response
command to the USIM. Thus, EAP-SIM stopped to work after this change on
USIMs that expect the proper command.

If WPS isn't enabled, hostapd_cli returns 'OK' even though WPS doesn't
get activated because WPS context is not valid:
$ hostapd_cli wps_pbc
Selected interface 'wlan0'
OK
$ hostapd_cli wps_cancel
Selected interface 'wlan0'
OK
Fix this by returning appropriate error when WPS fails to activate:
$ hostapd_cli wps_pbc
Selected interface 'wlan0'
FAIL
$ hostapd_cli wps_cancel
Selected interface 'wlan0'
FAIL
