Instead of using X509_print_fp() to print directly to stdout, print the
certificate dump to a memory BIO and use wpa_printf() to get this into
the debug log. This allows redirection of debug log to work better and
avoids undesired stdout prints when debugging is not enabled.

Commit 04eff7d5ba or something around that
timeframe may have caused a regression on how drv->if_indices gets used
with wpa_supplicant. Most (curretly likely all) wpa_supplicant virtual
interface use cases should not actually use this. This could result in
issues with P2P group interfaces delivering events to incorrect
interface (parent rather than the group interface). The previous commit
removed some of the issues, but more complete fix is to undo some of
those merged hostapd/wpa_supplicant operations.
Filter add_ifidx() uses based on hostapd vs. wpa_supplicant and iftype
to get closer to the earlier wpa_supplicant behavior for the driver
events from virtual interfaces.

It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.
This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.
Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.

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.

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.

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
from a previous AP mode operation could end up having been used as the
channel when trying to send Authentication frames in an RSN IBSS. This
resulted in the frame not sent (cfg80211 rejects it) and potentially not
being able to re-establish connection due to 4-way handshake failing
with replay counter mismatches. Fix this by learning the operating
channel of the IBSS both when join event is received and when a
management frame is being transmitted since the IBSS may have changed
channels due to merges.

The extra data (nonce_s) used in this message was pointing to the
parsed, decrypted data and that buffer was previously freed just before
building the new message. This resulted in use of freed data and
possibly incorrect extra data value that caused the authentication

data only after the new message has been generated. This was already the
case for EAP-AKA/AKA', but somehow missing from EAP-SIM.
