You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.175.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:35, 2 September 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Tomoyo Linux''' (stylised as ''TOMOYO Linux'') is a [[Linux kernel]] [[Linux Security Modules|security module]] which implements [[mandatory access control]] (MAC). 

==Overview==
Tomoyo Linux is a MAC implementation for [[Linux]] that can be used to increase the security of a system, while also being useful purely as a [[systems analysis]] tool. It was launched in March 2003 and was sponsored by [[NTT Data Corporation]] until March 2012.<ref>((cite web|url=http://tomoyo.osdn.jp/ |title=Tomoyo Linux Home Page |publisher=Tomoyo.osdn.jp |access-date=2013-05-23))</ref>

Tomoyo Linux focuses on system behaviour. Tomoyo Linux allows each process to declare behaviours and resources needed to achieve their purpose. When protection is enabled, Tomoyo Linux restricts each process to the behaviours and resources allowed by the administrator.

==Features==
The main features of Tomoyo Linux include:

*System analysis
*Increased security through Mandatory Access Control
*Automatic policy generation
*Simple syntax
*Ease of use

==History and versions==
Tomoyo was merged in [[Linux Kernel]] mainline version 2.6.30 (2009, June 10)/<ref>((cite web |title=Tomoyo Linux, an alternative Mandatory Access Control |publisher=Linux Kernel Newbies |work=Linux 2 6 30 |url=http://kernelnewbies.org/Linux_2_6_30#head-eeb259e0ba81d96d59015b8f79456d9a5283c650))</ref> It is currently one of four standard [[Linux Security Modules]] (LSM), along with [[SELinux]], [[AppArmor]] and [[Smack (Linux security module)|SMACK]].

The Tomoyo Linux project started as a patch for the Linux kernel to provide MAC. Porting Tomoyo Linux to the mainline Linux kernel required the introduction of hooks<ref>((cite web |title=Tomoyo #14 patch submission to LKML |publisher=LWN.net |url=https://lwn.net/Articles/313346/))</ref> into the LSM that had been designed and developed specifically to support SELinux and its label-based approach.

However, more hooks are needed to integrate the remaining MAC functionality of Tomoyo Linux. Consequently, the project is following two parallel development lines:
(( column|num=3
|1=
'''Tomoyo Linux 1.x''', original version
*uses purposely created non-standard hooks
*fully featured MAC
*released as a patch for Linux kernel – Since this version 1.x does not depend on LSM, it can be used with Linux kernel 2.6 (starting from version 2.6.11) as well as 2.4.
*latest version: 1.7.1
|2=
'''Tomoyo Linux 2.x''', mainline version
*uses standard [[Linux Security Modules|LSM]] hooks
*[http://tomoyo.osdn.jp/comparison.html.en fewer features]
*integral part of Linux kernel version 2.6.30
*latest version: 2.5.0 included in Linux kernel 3.2
|3=
'''Akari''' (stylised as ''AKARI''), Tomoyo 1.x fork
*uses standard [[Linux Security Modules|LSM]] hooks
*[http://akari.osdn.jp/comparison.html.en fewer features than Tomoyo 1.x, but more than Tomoyo 2.x]
*released as [[Loadable Kernel Module|LKM]] (Loadable Kernel Module), so [http://akari.osdn.jp/documentation.html.en no recompilation of the kernel is necessary]
))

==Naming==
The name 'TOMOYO' is, officially speaking, a [[backronym]] for "Task Oriented Management Obviates Your Onus". According to one of the developers Tetsuo Handa, it's also a reference to the character Tomoyo Daidouji from [[Cardcaptor Sakura]].<ref>((cite web | url=http://tomoyo.osdn.jp/wiki/?QandA | archive-url=https://web.archive.org/web/20151225071705/http://tomoyo.osdn.jp/wiki/?QandA | archive-date=2015-12-25 | title=QandA - TOMOYO Linux Wiki ))</ref>
