This is the simple script used for the wireless connection attempts:
ifdown <device_name>
ip link set <device_name> up
pkill wpa_supplicant
wpa_passphrase <essid> <password> > <conf_file>
wpa_supplicant -B -c<conf_file> -i<device_name>
rm -f /run/network/ifstate.<device_name>
ip link set <device_name> up
sleep 1
ifup <device_name>
Maybe, the lines nº 6 and nº7 are superfluous. The line nº8 (that
is, "sleep 1") is important, believe it.
As sysadmins, what do you think about the use of "pkill wpa_supplicant"?

This script needs granted permissions; so, it's included in a suid
binary. Once i talked about a security key for this binary.
The security key would be generated during the compilation of the
application in a way that only those binaries built *together* with
the suid binary will know it.
First of all, i have to deal with the add_custom_command() function
of CMake, in order to control the preference of the targets.
The first step should be to generate this key, before all the
executables.

The idea is very simple. The GUI and the suid binary will contain a
non-existent header:
#include "key.h"
The key.h file will contain an unique line (the random definition of
the KEY varible) edited by CMake during the compilation. For example:
var1="#define KEY "
var2=`tr -cd '[:alnum:]' < /dev/urandom | fold -w32 | head -n1`
echo "${var1}\"${var2}\"" > key.h
would generate something like this:
#define KEY "X1AULvFge6Tgq1p9BZat4EEVqAwaCnsB"
and then, the suid binary only will be able to be run from the GUI,
built together with it.

I had an issue packaging simple-netaid. The target of the shared library
"libnetaid.so" was being obj-x86-64-linux-gnu, and trying to use the
variable $(DEB_HOST_MULTIARCH)
in "libnetaid.install", this variable was not replaced by its value:
`x86-64-linux-gnu`. I've just found the following solution for that
doing the "libnetaid.install" executable:
#! /usr/bin/dh-exec
obj-*-linux-gnu/backend_src/libnetaid.so usr/lib/${DEB_HOST_MULTIARCH}
Cheers,
Aitor.
