ecbb0b3dc1 WPS: Reject a Credential with invalid passphrase
WPA/WPA2-Personal passphrase is not allowed to include control
characters. Reject a Credential received from a WPS Registrar both as
STA (Credential) and AP (AP Settings) if the credential is for WPAPSK or
WPA2PSK authentication type and includes an invalid passphrase.

This fixes an issue where hostapd or wpa_supplicant could have updated
the configuration file PSK/passphrase parameter with arbitrary data from
an external device (Registrar) that may not be fully trusted. Should
such data include a newline character, the resulting configuration file
could become invalid and fail to be parsed.

a218e1ded4 Make sure configuration is saved to storage device
Config file is written to a temp file and then it is renamed to the
original config file. However, it is possible that the rename operation
will be commited to storage while file data will be still in cache
causing original config file to be empty or partially written in case of
a system reboot without a clean shutdown. Make this less likely to occur
by forcing the data to be written to the storage device before renaming
the file.

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.

acbd59d0a8 eloop: Try to terminate more quickly on SIGINT and SIGTERM
It was possible for the SIGINT/SIGTERM signal to be received while
processing a pending timeout/socket/signal event and then get stuck in
the following select() call before processing the signal event. If no
other events show up within the two second SIGALRM trigger, process will
be terminated forcefully even though there would have been possibility
to do clean termination assuming no operationg blocked for that two
second time.

Handle this more cleanly by checking for eloop.pending_terminate before
starting the select()/poll()/epoll_wait() wait for the following event.
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.
