            <h5>Everything thanks to a guy from the internet</h5>
            <p>When the T42 died the time that I could spend on this project were significatly reduced. Android 5 support were probably ready on summer.</p>
            <p>But now, cSploit works on Android 5!</p>
            <p>All this thanks to one guy, he contacted me via email after I wrote about my old T42 and purchased me an used T60 notebook.</p>

            <p>This kindfull act make me proud about our growing community.</p>

            <h5>Hack and trick</h5>
            <h6><b>Network Radar</b></h6>
            <p>The first issue fixed on Android 5 were with the replacement of <b>NetworkDiscovery</b>. <b>NetworkDiscovery</b> were wrote in java and opens a lot of sockets for searching hosts in your local subnet. that was horrible :D. All these opened sockets made cSploit reach the maximum number of opened files on Android 5.</p>

            <p>I rewrote it <b>completely</b> in plain ANSI C.</p>
            <p>I changed it's name to <b>NetworkRadar</b>, thus to give a better idea of what it does. for more infos about this component of cSploit visit the <a href="https://github.com/cSploit/network-radar/" >project page</a>.</p>

            <h6><b>Socket context</b></h6>
            <p>Tthe second issue I fixed were a selinux restriction about accessing the <b>/dev/socket</b> folder. Moving the cSploit UNIX socket inside the app folder fixed this.</p>
            
            <h6><b>PIE</b></h6>
            <p>Last but not least problem were the PIE restricion (Position Indipendent Executables). Android 5 support only executables compiled with the PIE flag. android version prior to <i>JELLY_BEAN</i> does not support this kind of executables.</p>

            <p>My choice for fixing this problem were to build the core and the ruby package twice, one for the PIE platforms and one for the non PIE platform.</p>

            <p>cSploit will detect your platform on boot and install the right core.</p>

            <p>This solution have many impacts on many aspect of cSploit. First of all the APK size is reduced from ~10MB to ~3MB. this means a faster startup of the application ;)</p>

            <p>Another aspect is that we can now create ad-hoc core packages. Say that one day a particular bug on many devices is found, well just detect the bug on boot and download the ad-hoc core package.</p>
