Jouni Malinen a7803b0caf BoringSSL: Fix session resumption
BoringSSL commit 533ef7304d9b48aad38805f1997031a0a034d7fe ('Remove
SSL_clear calls in handshake functions.') triggered a regression for
EAP-TLS/TTLS/PEAP session resumption in wpa_supplicant due to the
removed SSL_clear() call in ssl3_connect() going away and wpa_supplicant
not calling SSL_clear() after SSL_shutdown(). Fix this by adding the
SSL_clear() call into wpa_supplicant after SSL_shutdown() when preparing
the ssl instance for another connection.

While OpenSSL is still call SSL_clear() in ssl3_connect(), it looks to
be safe to add this call to wpa_supplicant unconditionally.

Jouni Malinen 44fa5e747b FT: Remove optional fields from RSNE when using PMF
The PMKIDCount, PMKID List, and Group Management Cipher Suite fields are
optional to include in the RSNE in cases where these would not have
values that are different from the default values. In practice,
PMKIDCount is always 0 in Beacon and Probe Response frames, so the only
field of these that could have a non-default value is Group Management
Cipher Suite. When BIP is used, that field is not needed either due to
BIP being the default cipher when PMF is enabled.

Remove these fields from RSNE when BIP is used to save six octets in
Beacon and Probe Response frames. In addition to reduced frame length,
this is a workaround for interoperability issues with iOS 8.4 in cases
where FT and PMF are enabled. iOS seems to be rejecting EAPOL-Key msg
3/4 during FT initial mobility domain association if the RSNE includes
the PMKIDCount field.

Change P2PS P2P-PROV-SHOW-PIN/P2P-PROV-ENTER-PIN event notifications
on PD Request/Response handling to meet required P2PS behavior.

The new implemented scheme:
1. For a legacy P2P provision discovery the event behavior remains
   without changes
2. P2PS PD, advertiser method: DISPLAY, autoaccept: TRUE:
   Advertiser: SHOW-PIN on PD request replied with a status SUCCESS
   Seeker: ENTER-PIN on PD response received with a status SUCCESS
3. P2PS PD, advertiser method: DISPLAY, autoaccept: FALSE:
   Advertiser: SHOW-PIN on PD request replied with a status
     INFO_CURRENTLY_UNAVAILABLE
   Seeker: ENTER-PIN on Follow-on PD request with a status
     SUCCESS_DEFERRED
4. P2PS PD, advertiser method: KEYPAD, autoaccept: TRUE/FALSE:
   Advertiser: ENTER-PIN on PD request replied with a status
     INFO_CURRENTLY_UNAVAILABLE
   Seeker: SHOW-PIN on PD response received with a status
     INFO_CURRENTLY_UNAVAILABLE

This change in behavior breaks the existing test cases
p2ps_connect_keypad_method_nonautoaccept and
p2ps_connect_display_method_nonautoaccept. Those will be fixed in a
followup commit.

Masashi Honma ecd40fef74 mesh: Fix mesh SAE auth on low spec devices
The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.

After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).

On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().

So this patch makes the default to 1000(msec) and makes it configurable.

This issue does not occur on infrastructure SAE because the
dot11RSNASAERetransPeriod is not used on it.

Ahmad Kholaif 0ef54bd30e P2P: Do not omit known operating channel preference from GO Neg Resp
Add an extra condition to omit operating channel preference when
building GO Negotiation Response. If the local device supports the
preferred frequency list extension, then when sending a GO Negotiation
Response frame, advertise the preferred operating channel unless local
device is assuming the P2P Client role and has an empty preferred
frequency list, in which case local device can omit its preference for
the operating channel.

This change helps make use of the preferred frequency list and the
calculated best channel for both negotiating parties of the P2P
connection.

Jouni Malinen 7c524a64c1 eloop: Fix cases where a socket is reopened from a timeout/signal handler
It was possible for a registered eloop socket handler to be unregistered
and re-registered for a re-opened socket with the same fd from a timeout
or signal handler. If such a case happened with the old socket having a
pending event waiting for processing, some eloop combinations could end
up calling the new handler function with the new socket and get stuck
waiting for an event that has not yet happened on the new socket. This
happened with timeout and signal handlers with all eloop.c types. In
addition to that, the epoll case could also trigger this when a socket
handler re-registered a re-opened socket.

Fix these by checking whether there has been socket handler changes
during processing and break the processing round by going back to
select/poll/epoll for an updated result if any changes are done during
the eloop handler calls before processing the old socket results.

be terminated forcefully even though there would have been possibility

Terminate the loop if pending signal handling requests termination.

In addition, make eloop_terminated() return 1 on eloop.pending_terminate
in addition to eloop.terminate since the process will be terminated
shortly and there is no point in starting additional processing.
