EV_SET() for EV_ADD used a specific filter type, but that same filter
type was not provided to the matching EV_DELETE case. This resulted in
the kernel rejecting the deletion with "Invalid argument". Fix this by
setting the same filter type for both operations.

The previous implementation did not work if the first registered socket
had fd > 16 or if the fd was more than double the largest value used in
previous registrations. Those cases could result in too small a memory
allocation being used and writes/reads beyond the end of that buffer.
This fix is applicable to CONFIG_ELOOP_EPOLL=y and CONFIG_ELOOP_KQUEUE=y
builds.

According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:
"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."
An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.
It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).

In 2013 or so, IFNAME=foo was prepended to at least the Unix socket
communication from wpa_supplicant to wpa_cli. This broke the (fragile)
logic that made ping/pong work more often when wpa_supplicant is busy
sending logging info to wpa_cli.
Adding check for IFNAME=foo makes this work better.

Use of country=00 (world roaming) seemed to not work anymore with the
current cfg80211 regulatory implementation since the existing channel is
left enabled when moving to country=00. Use a specific country code that
does enforce the selected channel from being used anymore to make this
test case pass again.
The change in cfg80211 behavior is from the kernel commit 113f3aaa81bd

An AP might refuse to connect a STA if it has a low RSSI. In such case,

When a dedicated P2P device interface is used, the
global->p2p_group_formation was not set in wpas_p2p_join_start() if no
separate group interface is used. This would cause that in case of a
failure in group formation, the cleaning of p2p_in_provisioning is done
on the wrong interface. Furthermore, P2P_CANCEL command could not be
used to stop such a group-join operation. Fix this by setting the
global->p2p_group_formation correctly in case that the group interface
is reusing wpa_s->parent.

This allows more accurate logging of failures related to the cfg80211
country=98 (intersection) case. This version is trying to give some more
time to allow the country code to clear, but that does not seem to be
sufficient with the current cfg80211 implementation for country=98 (but
might be for other cases).
The additional check for country=98 at the beginning of each test case
is an attempt to force cfg80211 to restore world roaming state with a
new association and disconnection at the station side detected after the
AP side has already stopped. This is needed after the Linux kernel
commit 113f3aaa81bd ("cfg80211: Prevent regulatory restore during STA

Add the ability to ignore time-based CRL errors from OpenSSL by
specifying a new configuration parameter, check_crl_strict=0.
This causes the following:
- This setting does nothing when CRL checking is not enabled.
- When CRL is enabled, "strict mode" will cause CRL time errors to not
be ignored and will continue behaving as it currently does.
- When CRL is enabled, disabling strict mode will cause CRL time
errors to be ignored and will allow connections.
By default, check_crl_strict is set to 1, or strict mode, to keep
current functionality.

IEEE Std 802.1X-2010, 11.11 describes that the ICV is separate from the
parameter sets before it. Due to its convenient layout the ICV Indicator
'body part' is used to encode the ICV as well.
IEEE Std 802.1X-2010, 11.11.3 describes the encoding of MKPDUs. In
bullet e) is desribed that the ICV Indicator itself is encoded when the
ICV is not 16 octets in length. IEEE Std 802.1Xbx-2014, Table 11-7 note
e) states that it will not be encoded unless the Algorithm Agility
parameter specifies the use of an ICV that is not 16 octets in length.
Therefore the length calculation for the ICV indicator body part must
take into account if the ICV Indicator is to be encoded or not. The
actual encoder of the ICV body already takes care of the rest.
In practice, this change will remove the ICV Indicator parameter set (4
octets before the ICV value itself) since the only defined algorithm
agility value uses an ICV of 16 octets. IEEE Std 802.1X-2010 MKPDU
validation and decoding rules in 11.11.2 and 11.11.4 require the
receipient to handle both cases of ICV Indicator being included or not.
