I"± <p>I hate xv6, a stupid, useless education-oriented system. In this article, I will generally talk about how to implement system call to this operating system.</p>
|
||||
|
||||
<h2 id="xv6-systemcall">Xv6 Systemcall</h2>
|
||||
<p>To invoke a system call, we have to first define a user mode function to be the interface of the kernel instruction in file <em>user.h</em>.</p>
|
||||
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kt">void</span> <span class="nf">function</span> <span class="p">(</span><span class="kt">void</span><span class="p">);</span>
|
||||
</code></pre></div></div>
|
||||
|
||||
<p>This interface-like function will then pass the function name, in this case function, to <em>usys.S</em>. When using user mode function in programs, <em>usys.S</em> will generate a reference to SYS_function and push system call number of this function into %eax. After that, system can know from <em>syscall.c</em> and determining whether this system call is available. We must define same name system function and add it into <em>syscall.h</em> and <em>syscall.c</em>.</p>
|
||||
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="cp">#define SYS_function ## // ## is the system call number
|
||||
</span><span class="p">[</span><span class="n">SYS_function</span><span class="p">]</span> <span class="n">sys_function</span> <span class="c1">// real system function name</span>
|
||||
<span class="k">extern</span> <span class="kt">int</span> <span class="nf">sys_function</span><span class="p">(</span><span class="kt">void</span><span class="p">);</span> <span class="c1">// real system function declaration</span>
|
||||
</code></pre></div></div>
|
||||
|
||||
<p>After adding these sentences to syscall files, we can implement real function in specific place where you want to make the function works well.</p>
|
||||
|
||||
<p>Sometimes, we need to pass variables among system calls. In this case, variables’ values are not necessary and even can’t be pass directly into system_function. When invoke a system call function, all variables of this system call will be pushed into current process’ stack. In file <em>syscall.c</em>, multiple functions are provided to get these variables from the process. I won’t waste time on explaining how to use these functions especially when elegant and detailed comments were written in source codes. However, I will explain concepts and how process organized and works in xv6 in future articles.</p>

I"Ó<p>In this blog, I will generally talk about how to use proper tools to monitor SSL traffics of a mobile devices. Currently, I only can dealing with those SSL traffics which use an obviously certification. Some applications may not using system root cert or they doesn’t provide us a method to modify their own certs. For these situation, I still didn’t find a good solutions for it. But I’ll keep updating this if I get one.<br />
|
||||
My current solution is using AP to forward all SSL traffic to a proxy, <a href="https://www.charlesproxy.com/">charles proxy</a> is my first choice (Prof asked). It’s a non-free software which still update new versions now. So mainly, I’ll talk about how to charles SSL proxy.</p>

But we also need some bash script to collect data through different size of random size and with different modification through them.</p>

<li>After using this auto testing script, everything of output will be marked in log files of seafile, which located in <strong>~/.ccnet/log/seafile.log</strong></li>

<h3 id="install-seafile-on-odroid-xu">Install Seafile on odroid xu</h3>
|
||||
|
||||
<p>Due to failure of my cross-compile to seafile on android. I used develop board as a replacement experiment platform for ARM-seafile testing. I used a <a href="http://www.hardkernel.com/main/products/prdt_info.php?g_code=G137510300620">odroid xu</a> as hardware standard. Because all I need is an ARM platform, only an ARM-Ubuntu is enough for me. But develop prototype on a board is much fun than coding, I won’t address much this time. But I’ll start a blog telling some really cool stuff I made for a strange aim.</p>
|
||||
|
||||
<p>To install a ubuntu with GUI is my all preparation work. I found to way to do this.</p>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
<p><a href="http://www.armhf.com/boards/odroid-xu/">armhf</a> is a website for arm-based ubuntu. It has a detailed instruction to follow at <a href="http://www.armhf.com/boards/odroid-xu/odroid-sd-install/">here</a>. They also provide ubuntu 12.04/ 14.04 and debian 7.5 to choose. But unfortunately odroid xu’s hdmi output doesn’t supported by ubuntu native firmware. So install ubuntu-desktop might can’t be boot up for video output.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p>Burn images is much easy to install a pre-complied ubuntu system. I found this on odroid xu’s forum, which contains xubuntu image [<a href="http://odroid.in/ubuntu_14.04lts/ubuntu-14.04lts-xubuntu-odroid-xu-20140714.img.xz">download</a>] for odroid xu. With this image, you just need to use dd command to write whole system mirror into sdcard.</p>

||||

I"ò<p>In this blog, I will generally talk about how to use proper tools to monitor SSL traffics of a mobile devices. Currently, I only can dealing with those SSL traffics which use an obviously certification. Some applications may not using system root cert or they doesn’t provide us a method to modify their own certs. For these situation, I still didn’t find a good solutions for it. But I’ll keep updating this if I get one.<br />
|
||||
My current solution is using AP to forward all SSL traffic to a proxy, <a href="https://www.charlesproxy.com/">charles proxy</a> is my first choice (Prof asked). It’s a non-free software which still update new versions now. So mainly, I’ll talk about how to charles SSL proxy.</p>

<h3 id="preparations">Preparations</h3>
|
||||
<ul>
|
||||
<li>Monitor device situation: Linux Machine with wireless adapter</li>
|
||||
<li>Download the newest version(4.0.1) of charles</li>
|

<li>Target android devices with root privilege</li>

</ul>
|
||||
|
||||
<p>In Help -> SSL Proxying -> Export Charles Root Certificate and Private Key, enter a password and save the public and private key in *.p12 format.<br />
|
||||
You also need to save charles Root Certificate, it also contains in the same menu. For convience, save it as *.pem format.</p>

<p>I hate xv6, a stupid, useless education-oriented system. In this article, I will generally talk about how to implement system call to this operating system.</p>

<hr />
|

|

<h2 id="xv6-systemcall">Xv6 Systemcall</h2>
|
||||
<p>To invoke a system call, we have to first define a user mode function to be the interface of the kernel instruction in file <em>user.h</em>.</p>

||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kt">void</span> <span class="n">function</span> <span class="p">(</span><span class="kt">void</span><span class="p">);</span>

|
||||
</code></pre></div></div>
|
||||
|
||||
<p>This interface-like function will then pass the function name, in this case function, to <em>usys.S</em>. When using user mode function in programs, <em>usys.S</em> will generate a reference to SYS_function and push system call number of this function into %eax. After that, system can know from <em>syscall.c</em> and determining whether this system call is available. We must define same name system function and add it into <em>syscall.h</em> and <em>syscall.c</em>.</p>
|
||||
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="cp">#define SYS_function ## // ## is the system call number

<p>After adding these sentences to syscall files, we can implement real function in specific place where you want to make the function works well.</p>

<title>Xv6 introduction</title>
|
||||
<description><p>I hate xv6, a stupid, useless education-oriented system. In this article, I will generally talk about how to implement system call to this operating system.</p>
|
||||
|
||||
<hr />
|
||||
|
||||
<h2 id="xv6-systemcall">Xv6 Systemcall</h2>
|
||||
<p>To invoke a system call, we have to first define a user mode function to be the interface of the kernel instruction in file <em>user.h</em>.</p>
|
||||
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kt">void</span> <span class="n">function</span> <span class="p">(</span><span class="kt">void</span><span class="p">);</span>
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="kt">void</span> <span class="nf">function</span> <span class="p">(</span><span class="kt">void</span><span class="p">);</span>
|
||||
</code></pre></div></div>
|
||||
|
||||
<p>This interface-like function will then pass the function name, in this case function, to <em>usys.S</em>. When using user mode function in programs, <em>usys.S</em> will generate a reference to SYS_function and push system call number of this function into %eax. After that, system can know from <em>syscall.c</em> and determining whether this system call is available. We must define same name system function and add it into <em>syscall.h</em> and <em>syscall.c</em>.</p>
|
||||
|
||||
<div class="language-c highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="cp">#define SYS_function ## // ## is the system call number
|
||||
</span><span class="p">[</span><span class="n">SYS_function</span><span class="p">]</span> <span class="n">sys_function</span> <span class="c1">// real system function name</span>
|
||||
<span class="k">extern</span> <span class="kt">int</span> <span class="n">sys_function</span><span class="p">(</span><span class="kt">void</span><span class="p">);</span> <span class="c1">// real system function declaration</span>
|
||||
<span class="k">extern</span> <span class="kt">int</span> <span class="nf">sys_function</span><span class="p">(</span><span class="kt">void</span><span class="p">);</span> <span class="c1">// real system function declaration</span>
|
||||
</code></pre></div></div>
|
||||
|
||||
<p>After adding these sentences to syscall files, we can implement real function in specific place where you want to make the function works well.</p>

<p>In this blog, I will generally talk about how to use proper tools to monitor SSL traffics of a mobile devices. Currently, I only can dealing with those SSL traffics which use an obviously certification. Some applications may not using system root cert or they doesn’t provide us a method to modify their own certs. For these situation, I still didn’t find a good solutions for it. But I’ll keep updating this if I get one.<br />
|
||||
My current solution is using AP to forward all SSL traffic to a proxy, <a href="https://www.charlesproxy.com/">charles proxy</a> is my first choice (Prof asked). It’s a non-free software which still update new versions now. So mainly, I’ll talk about how to charles SSL proxy.</p>
