+However, you will eventually need to keep some changes on your policy, due to

+</p>
+
+<p>
+Updates on the policy are only possible as long as you need to <e>allow</e>
+additional privileges. It is not possible to remove rules from the policy, only
+enhance it. To maintain your own set of additional rules, create a file in which
+you will keep your changes. In the next example, I will use the term
+<path>fixlocal</path>, substitute with whatever name you like - but keep it
+consistent. In the file (<path>fixlocal.te</path>) put in the following text
+(again, substitute <path>fixlocal</path> with your chosen name):

+}
+
+<comment># Declaration of policy rules</comment>
+</pre>
+
+<p>
+In this file, you can add rules as you like. In the next example, we add three
+rules:
+</p>
+
+<ol>
+ <li>
+ Allow <c>mozilla_t</c> the <c>execmem</c> privilege (based on a denial that
+ occurs when mozilla fails to start)
+ </li>
+ <li>
+ Allow <c>ssh_t</c> to connect to any port rather than just the SSH port
+ </li>
+ <li>
+ Allows the <c>user_t</c> domain to send messages directly to the system
+ logger
+ </li>
+</ol>
+
+<pre caption="fixlocal.te content">
+policy_module(fixlocal, 1.0)

+require {
+ type mozilla_t;
+ type ssh_t;

+</pre>
+
+<p>
+If you need to provide raw allow statements (like the one above for the
+<c>mozilla_t</c> domain), make sure that the type (<c>mozilla_t</c>),
+class (<c>process</c>) and privilege (<c>execmem</c>) are mentioned in
+the <c>require { ... }</c> paragraph.
+</p>
+
+<p>
+When using interface names, make sure that the type (<c>ssh_t</c> and
+<c>user_t</c>) is mentioned in the <c>require { ... }</c> paragraph.
+</p>
+
+<p>
+To find the proper interface name (like <c>corenet_tcp_connect_all_ports</c>
+above), you can either look for it in the <uri
+link="http://oss.tresys.com/docs/refpolicy/api/">SELinux Reference Policy
+API</uri> online or, if <c>sec-policy/selinux-base-policy</c> is built with the

+Of course, you can also ask for help in <c>#gentoo-hardened</c> on

+From Linux 3.4, improved AppArmor support has been merged into the kernel. For the best experience, however,
+it is recommended to patch your kernel with additional support. Without patching, it will only be possible to activate
+profiles - deactivation, listing, init script etc. will not work.
+</p>
+<p>
+The required patches are included in the AppArmor tarball. If you are using a grsec enabled kernel, such as <c>hardened-sources</c>,
+the patches will not cleanly apply. For convenience, a rebased version of the patches is

+<body>
+
+<p>
+Users who boot with an initramfs will need to boot in permissive mode first, and
+later on switch to enforcing mode. This can be done automatically using an
+init script, as documented at <uri

+<title>2012/05/26 - Support for graphical login managers</title>
+<body>
+
+<p>
+Users who boot into a graphical environment (such as through GDM) will need to
+edit their PAM configuration files accordingly to support SELinux security
+context settings. This is documented at <uri

+<body>
+
+<p>
+The previously documented editing of <path>/etc/sandbox.conf</path> to open
+write access to <path>/sys/fs/selinux/context</path> can be removed as the
+SELinux profile does this now automatically.

+
+<p>
+The previously documented /dev mount line in <path>/etc/fstab</path> is no

+<p>
+We now support MLS and MCS, right next to targeted and strict SELinux policy
+types. When using MLS or MCS, you will need to update the <path>/tmp</path>
+entry in your <path>/etc/fstab</path> to use
+<c>rootcontext=system_u:object_r:tmp_t:s0</c> (note the trailing <c>:s0</c>).

+Users that have a <path>/run</path> location will need to mark this location in their
+<path>/etc/fstab</path> to make sure it gets mounted with the right SELinux
+context.

-<title>Using scanelf for Text Relocations</title>
-<body>
-
-<p>
-As an example, we will use <c>scanelf</c> to find binaries containing text
-relocations.
-</p>
-
-<p>
-A relocation is an operation that rewrites an address in a loaded segment. Such
-an address rewrite can happen when a segment has references to a shared object
-and that shared object is loaded in memory. In this case, the references are
-substituted with the real address values. Similar events can occur inside the
-shared object itself.
-</p>
-
-<p>
-A text relocation is a relocation in the text segment. Since text segments
-contain executable code, system administrators might prefer not to have these
-segments writable. This is perfectly possible, but since text relocations
-actually write in the text segment, it is not always feasible.
-</p>
-
-<p>
-If you want to eliminate text relocations, you will need to make sure
-that the application and shared object is built with <e>Position Independent
-Code</e> (PIC), making references obsolete. This not only increases security,
-but also increases the performance in case of shared objects (allowing writes in
-the text segment requires a swap space reservation and a private copy of the
-shared object for each application that uses it).
-</p>
-
-<p>
-The following example will search your library paths recursively, without
-leaving the mounted file system and ignoring symbolic links, for any ELF binary
-containing a text relocation:
-</p>
-
-<pre caption="Scanning the system for text relocation binaries">
-# <i>scanelf -lqtmyR</i>
-</pre>
-
-<p>
-If you want to scan your entire system for <e>any</e> file containing text
-relocations:
-</p>
-
-<pre caption="Scanning the entire system for text relocation files">
-# <i>scanelf -qtmyR /</i>
-</pre>
-
-</body>
-</section>
-<section>
-<title>Using scanelf for Specific Header</title>
-<body>
-
-<p>
-The scanelf util can be used to quickly identify files that contain a
-given section header using the -k .section option.
-</p>
-
-<p>
-In this example we are looking for all files in /usr/lib/debug
-recursively using a format modifier with quiet mode enabled that have been
-stripped. A stripped elf will lack a .symtab entry, so we use the '!'
-to invert the matching logic.
-</p>
-
-<pre caption="Scanning for stripped or non stripped executables">
-# <i>scanelf -k '!.symtab' /usr/lib/debug -Rq -F%F#k</i>
-</pre>
-
-</body>
-</section>
-<section>
-<title>Using scanelf for Specific Segment Markings</title>
-<body>
-
-<p>
-Each segment has specific flags assigned to it in the Program Header of the
-binary. One of those flags is the type of the segment. Interesting values are
-PT_LOAD (the segment must be loaded in memory from file), PT_DYNAMIC (the
-segment contains dynamic linking information), PT_INTERP (the segment
-contains the name of the program interpreter), PT_GNU_STACK (a GNU extension
-for the ELF format, used by some stack protection mechanisms), and PT_PAX_FLAGS
-(a PaX extension for the ELF format, used by the security-minded
-<uri link="http://pax.grsecurity.net/">PaX Project</uri>.
-</p>
-
-<p>
-If we want to scan all executables in the current working directory, PATH
-environment and library paths and report those who have a writable and
-executable PT_LOAD or PT_GNU_STACK marking, you could use the following command:
-</p>
-
-<pre caption="Scanning for Write/eXecute flags for PT_LOAD and PT_GNU_STACK">
-# <i>scanelf -lpqe .</i>
-</pre>
-
-</body>
-</section>
-<section>
-<title>Using scanelf's Format Modifier Handler</title>
-<body>
-
-<p>
-A useful feature of the <c>scanelf</c> utility is the format modifier handler.
-With this option you can control the output of <c>scanelf</c>, thereby
-simplifying parsing the output with scripts.
-</p>
-
-<p>
-As an example, we will use <c>scanelf</c> to print the file names that contain
-text relocations:
-</p>
-
-<pre caption="Example of the scanelf format modifier handler">
-# <i>scanelf -l -p -R -q -F "%F #t"</i>
+utility. What it does is check all the libraries linked statically by the
+binaries using <c>ldd</c> and then smartly add the paxmarks of those libraries
+to generate the new set. As a result if <path>/usr/games/bin/armagetronad</path>
+links with <path>/usr/lib64/libGL.so.1</path> which has the <e>-m</e> PaX mark
+(allow RWX mappings) because you are using a llvm requiring graphics driver
+you'll get that binary marked with the <e>-m</e> PaX mark too since it needs it.
+Below you can see how to run it.
+</p>
+
+<pre caption="Propagating the PaX marks from the libraries">

-goal is "to research various defense mechanisms against the exploitation of

-various forms of buffer overflow bugs (be they stack or heap based), user

+<title>What's <c>revdep-pax</c> about?</title>
+
+<p by="Geroge Orwell">
+Since the early days of PaX it was known that all programs were equal although
+some were more equal than others and needed an environment with less
+restrictions in order to be able to run. Thus, in order to have a secure way of
+allowing system administrators and users telling the system which binaries
+needed this lessened environment the PaX marks were created.
+</p>
+
+<section>
+<title>A quick introduction to PaX markings.</title>
+<body>
+
+<p>
+There are some programs which won't be able to run in an environment with all
+the PaX features enabled, for example you may have a program which has so called
+<e>text relocations</e> or you may have a language interpreter doing JIT code
+compilation and requiring <e>RWX</e> mappings you may also have a program that
+saves data including internal pointers into an mmaped file and which needs to be
+restored in the same place no matter what. You could also be holding a security
+competition and need to disable the execution restrictions and force it to
+use fixed addresses on a particular program so it can be exploited doing a
+simple nop sled based stack overflow to get to the next level. For taking into
+account these issues binaries can be marked to force on or off some of the PaX
+features.
+</p>
+
+<p>
+Currently, the PaX features that can be lessened or enforced to allow programs
+to run are:
+</p>
+
+<dl>
+ <dt><b>PAGEEXEC</b></dt>
+ <dd>Paging based execution restrictions. This is what other OSes know as
+ <e>NX</e>.</dd>
+ <dt><b>EMUTRAMP</b></dt>
+ <dd>Trampoline emulation. Required by for amongst other things code with
+ nested functions.</dd>
+ <dt><b>MPROTECT</b></dt>
+ <dd>Prevents the introduction of new executable code in the task. This is the
+ one you are more likely to need disabling with libraries generating JIT code.
+ </dd>
+ <dt><b>RANDMMAP</b></dt>
+ <dd>Randomizes the addresses where mappings are made unless the program
+ explicitly requests one (using the MAP_FIXED flag).</dd>
+ <dt><b>RANDEXEC</b></dt>
+ <dd>This flag is currently deprecated and was used to enforce random placement
+ of the executable part of the binary.</dd>
+ <dt><b>SEGMEXEC</b></dt>
+ <dd>This flag enables segmentation based execution protection. This feature is
+ not available on the amd64 architecture so in that architecture is disables by
+ default.</dd>
+</dl>
+
+<p>
+There are various ways in which this advice to lessen the environment can be
+provided to the system, amongst others Mandatory Access Control rules, extended
+attributes and two kinds of markings on the binaries themselves, the legacy ones
+which abuse an unused field in the ELF headers and the new ones which add a new
+specific section to the ELF file with the markings.
+</p>
+
+<p>
+All this markings though are only read in the executable and not in the
+libraries linked by it to prevent some possible attacks (like libraries being
+injected via LD_PRELOAD) and because it eases a lot the implementation since the
+kernel shouldn't be aware of linking details.
+</p>
+
+<p>
+This system has a problem: if we have a binary linking to a library which
+requires, for example, trampoline emulation because it uses nested functions how
+can we make sure the binary gets the propper markings? Yeah we could add PaX
+marks to the library to state it needs trampoline emulation but still we haven't
+fixed the issue since the kernel will only read the marks on the binary being
+called. In order to solve this issue we have created <c>revdep-pax</c>.

+<title>What's <c>revdep-pax</c>?</title>
+<body>
+
+<p>
+<c>revdep-pax</c> is a tool that allows to check for differences in PaX markings
+between elf objects linking to libraries (for example <path>/bin/bash</path>)
+and the libraries themselves (for example <path>/lib64/libc.so.6</path>).
+</p>
+
+<p>
+<c>revdep-pax</c> is able to do this in various ways, it can check for
+differences <e>forward</e> from one binary to all the libraries it links and it
+can also check for PaX marking differences <e>backwards</e> from one library to
+all the binaries linking to it (which may include other libraries too). In a
+similar way it is possible to have all the forward and reverse mappings in the
+system checked to try finding issues.
+</p>
+
+<p>
+<c>revdep-pax</c> is also able to propagate these markings both forward to the
+libraries linked by an object and backwards to the objects linked by a library.

+<title>Using scanelf for Text Relocations</title>
+<body>
+
+<p>
+As an example, we will use <c>scanelf</c> to find binaries containing text
+relocations.
+</p>
+
+<p>
+A relocation is an operation that rewrites an address in a loaded segment. Such
+an address rewrite can happen when a segment has references to a shared object
+and that shared object is loaded in memory. In this case, the references are
+substituted with the real address values. Similar events can occur inside the
+shared object itself.
+</p>
+
+<p>
+A text relocation is a relocation in the text segment. Since text segments
+contain executable code, system administrators might prefer not to have these
+segments writable. This is perfectly possible, but since text relocations
+actually write in the text segment, it is not always feasible.
+</p>
+
+<p>
+If you want to eliminate text relocations, you will need to make sure
+that the application and shared object is built with <e>Position Independent
+Code</e> (PIC), making references obsolete. This not only increases security,
+but also increases the performance in case of shared objects (allowing writes in
+the text segment requires a swap space reservation and a private copy of the
+shared object for each application that uses it).
+</p>
+
+<p>
+The following example will search your library paths recursively, without
+leaving the mounted file system and ignoring symbolic links, for any ELF binary
+containing a text relocation:
+</p>
+
+<pre caption="Scanning the system for text relocation binaries">
+# <i>scanelf -lqtmyR</i>
+</pre>
+
+<p>
+If you want to scan your entire system for <e>any</e> file containing text
+relocations:
+</p>
+
+<pre caption="Scanning the entire system for text relocation files">
+# <i>scanelf -qtmyR /</i>
+</pre>
+
+</body>
+</section>
+<section>
+<title>Using scanelf for Specific Header</title>
+<body>
+
+<p>
+The scanelf util can be used to quickly identify files that contain a
+given section header using the -k .section option.
+</p>
+
+<p>
+In this example we are looking for all files in /usr/lib/debug
+recursively using a format modifier with quiet mode enabled that have been
+stripped. A stripped elf will lack a .symtab entry, so we use the '!'
+to invert the matching logic.
+</p>
+
+<pre caption="Scanning for stripped or non stripped executables">
+# <i>scanelf -k '!.symtab' /usr/lib/debug -Rq -F%F#k</i>
+</pre>
+
+</body>
+</section>
+<section>
+<title>Using scanelf for Specific Segment Markings</title>
+<body>
+
+<p>
+Each segment has specific flags assigned to it in the Program Header of the
+binary. One of those flags is the type of the segment. Interesting values are
+PT_LOAD (the segment must be loaded in memory from file), PT_DYNAMIC (the
+segment contains dynamic linking information), PT_INTERP (the segment
+contains the name of the program interpreter), PT_GNU_STACK (a GNU extension
+for the ELF format, used by some stack protection mechanisms), and PT_PAX_FLAGS
+(a PaX extension for the ELF format, used by the security-minded
+<uri link="http://pax.grsecurity.net/">PaX Project</uri>.
+</p>
+
+<p>
+If we want to scan all executables in the current working directory, PATH
+environment and library paths and report those who have a writable and
+executable PT_LOAD or PT_GNU_STACK marking, you could use the following command:
+</p>
+
+<pre caption="Scanning for Write/eXecute flags for PT_LOAD and PT_GNU_STACK">
+# <i>scanelf -lpqe .</i>

+<title>Using scanelf's Format Modifier Handler</title>
+<body>
+
+<p>
+A useful feature of the <c>scanelf</c> utility is the format modifier handler.
+With this option you can control the output of <c>scanelf</c>, thereby
+simplifying parsing the output with scripts.
+</p>
+
+<p>
+As an example, we will use <c>scanelf</c> to print the file names that contain
+text relocations:
+</p>
+
+<pre caption="Example of the scanelf format modifier handler">
+# <i>scanelf -l -p -R -q -F "%F #t"</i>

+
+<p>
+<uri link="http://pax.grsecurity.net">PaX</uri> is a project hosted by the <uri
+link="http://www.grsecurity.net">grsecurity</uri> project. Quoting the <uri
+link="http://pax.grsecurity.net/docs/pax.txt">PaX documentation</uri>, its main
+goal is "to research various defense mechanisms against the exploitation of
+software bugs that give an attacker arbitrary read/write access to the
+attacked task's address space. This class of bugs contains among others
+various forms of buffer overflow bugs (be they stack or heap based), user
+supplied format string bugs, etc."
+</p>
+
+<p>
+To be able to benefit from these defense mechanisms, you need to run a Linux
+kernel patched with the latest PaX code. The <uri
+link="http://hardened.gentoo.org">Hardened Gentoo</uri> project supports PaX and
+its parent project, grsecurity. The supported kernel package is
+<c>sys-kernel/hardened-sources</c>.

+<chapter>
+<title>So you got a bug?</title>
+<section>
+<title>Introduction</title>
+<body>
+
+<p>
+When working with a SELinux-enabled system, you will notice that some policies
+are far from perfect. That is to be expected, since there are a lot more
+policies and SELinux policy modules than we can thoroughly test. That is why bug
+reports are very important for us as they give us much-needed feedback on the
+state of the policies. Also, since we follow the reference policy closely,
+patches are also sent upstream so that other distributions can benefit from the
+updates.
+</p>
+
+<p>
+However, debugging and fixing SELinux policies also means that we need to
+identify a proper policy failure, find the root cause of this failure and have
+an optimal solution. Since we are talking about <e>security</e> policies, much
+attention goes into details, but also in the <e>many eyes</e> paradigm to
+validate if a policy fix is correct or not.
+</p>
+
+<p>
+That is one of the reasons why we created this bugreport as it helps you, as the
+feedback-providing user, to both properly figure out why a failure occurs and
+how to fix it, but also why we are quite strict in the acceptance of patches.
+</p>
+
+</body>
+</section>
+<section>
+<title>Short version</title>
+<body>
+
+<p>
+When reporting SELinux policy fixes based on AVC denials,
+</p>
+
+<ul>
+ <li>
+ structure the denials and try to create one bug report per logically
+ coherent set of denials. Don't push all your AVC denials onto us.
+ </li>
+ <li>
+ make sure you can reproduce the issue and that you have the ability to
+ reproduce while we work on the fix. We cannot test all policies ourselves.
+ </li>
+ <li>
+ report the application failure output as well, not only the AVC denial. We
+ need to know what the application is trying to do (and failing to do) to fix
+ the problem.
+ </li>

+<chapter>
+<title>Bugs related to AVC denials (and non-functional applications)</title>
+<section>
+<title>About</title>
+<body>
+
+<p>
+In this section, we'll go into the details of creating a helpful bug report for
+SELinux policies in case you have an AVC denial (which means SELinux is
+prohibiting a certain privilege request) that results in the failure of the
+application.
+</p>
+
+</body>
+</section>
+<section>
+<title>Structure the denials</title>
+<body>
+
+<p>
+When you get one or more AVC denials, try to structure them into logically
+coherent sets. We cannot easily deal with several dozen denials. Most of the
+time, you either get multiple denials of the same cause, or the denials are not
+truely related.
+</p>
+
+<p>
+When we need to fix the SELinux policy, nine out of ten times we focus on one or
+a few related denials and come up with a proper fix. When there is an abundance
+of AVC denials, we need to skim through them (which we usually then do one at a
+time) which puts a lot of stress on you (the reporter) as we will ask you
+hundred-and-one questions and requests for testing.
+</p>
+
+</body>
+</section>
+<section>
+<title>Prepare for testing</title>
+<body>
+
+<p>
+When you report a SELinux policy related bug, make sure you are ready to test
+the results that we want to put in. We cannot test out all applications
+ourselves. Sometimes, a failure is even only reproducable on a specific setup.
+</p>
+
+</body>
+</section>
+<section>
+<title>Report the application failure</title>
+<body>
+
+<p>
+More than once, we get bug reports on SELinux policy denials where the user is
+still running in permissive mode. He is reporting the denials because he is
+afraid that he will not be able to run it in enforcing mode without the denials
+being fixed.
+</p>
+
+<p>
+However, denials can be <e>cosmetic</e>, in which case we should actually hide
+the denials rather than allow their requests. Also, when you run in permissive
+mode, it is very much possible that the denials would never be reached when
+running in enforcing mode because of earlier denials (which, coincidentally,
+might be wrongly hidden from your logs).
+</p>
+
+<p>
+For this reason, we urge you to give us not only the AVC denial information, but
+also the application failure log output when running in enforcing mode.
+</p>
+
+<p>
+The <uri link="selinux/selinux-handbook.xml">Gentoo Hardened SELinux
+Handbook</uri> will guide you through the process of migrating from a permissive
+system into an enforcing mode. If you believe that booting in enforcing is not
+possible yet, just boot in permissive, log on as root, run <c>setenforce 1</c>
+and only then log on as user(s) to reproduce your situation. There is also a
+<uri link="selinux/selinux-handbook.xml?part=2&chap=2">Troubleshooting
+SELinux</uri> section that helps you identify common bottlenecks or issues while
+trying to get SELinux running on your system.
+</p>

+<body>
+
+<p>
+Portage uses the <c>setfiles</c> command to set the labels of the files it
+installs. However, that command is a dynamically linked executable, so any
+update in its depending libraries (<path>libselinux.so</path>,
+<path>libsepol.so</path>, <path>libaudit.so</path> and of course
+<path>libc.so</path>) might cause for the application to fail. Gentoo's standard
+solution (<c>revdep-rebuild</c>) will not work, since the tool will try to
+rebuild policycoreutils, which will fail to install because Portage cannot set
+the file labels.
+</p>
+
+<p>
+The solution is to rebuild policycoreutils while disabling Portage' selinux
+support, then label the installed files manually using <c>chcon</c>, based on
+the feedback received from <c>matchpathcon</c>.

+<p>
+When using <c>seinfo</c> or <c>sesearch</c> to query the policy on the system,
+you get errors similar to:
+</p>
+
+<pre caption="Triggering the 'could not find datum' error">
+~# <i>seinfo -tasterisk_t</i>
+ERROR: could not find datum for type asterisk_t
+</pre>
+
+<p>
+This is most likely because your tools are using a newer binary policy to
+enforce policy, but an older binary for querying. You can verify if this is the
+case by listing the last modification time on the files:
+</p>
+
+<pre caption="Checking last modification time of the policy files">
+~# <i>ls -ltr /etc/selinux/strict/policy/policy.*</i>
+</pre>
+
+<p>
+The file modified last should be the same one as returned by checking
+<path>/selinux/policyvers</path>:
+</p>
+
+<pre caption="Checking the runtime policy version">
+~# <i>cat /selinux/policyvers; echo</i>
+24
+</pre>
+
+<p>
+If this is not the case (which is very likely since you are reading this FAQ
+entry) then try forcing the utilities policy version to the correct version:
+</p>
+
+<pre caption="Editing semanage.conf">
+~# <i>vim /etc/selinux/semanage.conf</i>
+<comment># Look for and uncomment the policy-version line and set it to the right version</comment>
+policy-version = <i>24</i>
+</pre>
+
+<impo>
+If your system is upgrading its kernel, higher version(s) can be supported. In
+this case, either unset the value again to automatically "jump" to a higher
+version, or force set it to the higher version.

Add information on undefined permissions
A question that pops up on #gentoo-hardened from time to time is the error message displayed during boot about missing permissions. This FAQ entry should answer that question.

+<body>
+
+<p>
+The Gentoo Hardened project aims to support as many platforms as possible.
+However, this aim is restrained as we do not have access to as many platforms
+that we want (nor do we have the resources to work on all these platforms). As a
+result, support for the individual subprojects becomes limited to those
+platforms that we have access and resources to.
+</p>
+
+<p>
+This document gives an overview of the supported platforms and, if necessary,
+elaborates on the specific requirements in order to work with one of Gentoo
+Hardened's subprojects. Note that each subproject has its own support matrix,
+based on upstream support (which platforms are supported by the technology) and
+Gentoo Hardened (for which platforms can we run tests and validate users'
+reports and feedback).

+ What is the main vision that Gentoo Hardened strives towards?

+ take our decisions?
+-->
+
+<p>
+Within Gentoo Linux, the Gentoo Hardened project wants to be a shepherd for all
+security oriented projects. The project wants to make Gentoo viable for highly
+secure, high stability production environments.

+
+<!--
+ Our strategy should reflect our high-level choices and focuses. It should
+ describe what we aim for (in light of our vision) in a generic descriptive
+ approach. The strategy of Gentoo Hardened should be what we envision to be the
+ way to go forward to implement our vision. It should not change much in time.
+-->
+
+<p>
+In order to succesfully strive towards our vision, Gentoo Hardened aims to
+provide subprojects that test, develop, enhance, implement and integrate
+specific security measures in Gentoo Linux. Although each of these projects has
+operational responsibilities (after all, the technologies that they support are
+used by users all around) they continue to research and develop, making Gentoo
+Linux even better than it is today.
+</p>
+
+<p>
+The direction that each of these projects is heading towards is described in
+their <e>roadmap</e>, a combination of strategic directions and shorter term
+milestones. These roadmaps are combined in this very document, allowing users to
+get a general overview of where Gentoo Hardened is evolving towards.

+</section>
+<section>
+<title>Documentation</title>
+<body>
+
+<p>
+Documentation is Gentoo Hardened's first asset that users come in contact with.
+It is important that Gentoo Hardened's documentation is well structured, easily
+accessible and correctly written. Although we currently focus on technically
+educated users and system administrators, this focus should not lower our
+responsibility of creating the necessary documents to guide new users in Gentoo
+Hardened's realms.
+</p>
+
+</body>
+</section>
+<section>
+<title>Vulnerability Mitigation</title>
+<body>
+
+<p>
+Users use a <e>toolchain</e>, a set of libraries and tools like compilers,
+linkers and more, to build their systems with. To fight potential
+vulnerabilities and future exploits, Gentoo Hardened maintains a toolchain that
+supports additional security-enhancing features like SSP, PIE and PIC.
+Our focus is to enhance and maintain this toolchain and help the integration of
+these security-enhancing patchsets within the upstream communities so that the
+benefits are available for all Linux users.
+</p>
+
+<p>
+Yet toolchains are not the only method where risks can be reduced. Specific
+patch sets that enhance Linux' security-related capabilities exist, such as
+PAX, that help users mitigate the risk of succesful exploitation of
+vulnerabilities. Gentoo Hardened positions and integrates these patches in the
+distribution.
+</p>
+
+</body>
+</section>
+<section>
+<title>Access Control</title>
+<body>
+
+<p>
+Although definitely not the only security component of a system, proper access
+control is a prerequisite for a safer environment. Within Gentoo Hardened,
+support of proper access control systems is important, and reflected in our
+choices of enhanced development of SELinux, grSecurity RSBAC and more.
+</p>
+
+</body>
+</section>
+<section>
+<title>Architecture Support</title>
+<body>
+
+<p>
+The current primary development activities take place within the popular and
+commodity architectures x86 and amd64 (x86_64). Yet many other architectures
+exist, especially within the server and embedded/mobile environments. These
+architectures need to be properly supported as well.

+</section>
+<section>
+<title>Staffing</title>
+<body>
+
+<p>
+In order to sustain or even grow our research and development pace and keep
+supporting operational tasks and help out users, the Gentoo Hardened team is
+always looking for fresh blood. Users who take a proactive approach to finding
+places for improvement and filling in the holes should and will be noticed and
+probably recruited. Yet recruitment is not mandatory to help out our project.
+The necessary resources are put in place to let contributors efficiently help
+out the project.

-Now is the time to take a step back and examine the work that has been done so

-needed. There may be ways to strengthen the current implementation or areas of
-code that can be cleaned up to allow changes to be pushed upstream easier.
+The Gentoo Hardened project is currently lagging behind a bit on documentation.
+Recent upstaffing and contributions have helped this out, but we still need to
+focus on the toolchain documentation (both toolchain-specific documentation
+as wel as documents that relate to the toolchain) such as SSP, PIE and PIC
+information.
</p>
<p>
-As a side effect of the previous hardened toolchain, many ebuilds currently
-filter hardened CFLAGS such as -fPIE and -fstack-protector. Work will also be
-dedicated to reviewing those packages and seeking alternate solutions for the
-filters.
+Also, comparative documents should be written to explain the choices that Gentoo
+Hardened has made, such as tool selection.

+
+<p>
+Our toolchain so far has seen a tremendous evolution. Some of the integrated
+patches have been accepted upstream (like SSP), but work can still improve.
+To allow changes to be pushed upstream more easily, we might need improvements
+on the ways to strengthen the current implementation, and work on the areas of
+code that need clean-up.
+</p>
+
+<p>
+Our next steps are to take a step backwards and examine the work that has been
+done so far. We need to improve our existing documents, but also review the
+packages available in the Portage tree and help out the package maintainers in
+handling CFLAG filters for a hardened toolchain in a proper way.

-<section>
-<title>Documentation</title>
-<body>
-
-<p>
-The Hardened Gentoo Project is currently very lacking in documentation. The
-hardened toolchain needs to be documented fully, and older documents that have a
-relationship to the toolchain need to be updated, such as the SSP, PIE, and PIC
-documents. Also, comparative documents should be written to explain the choices
-that Hardened Gentoo has made in deciding which security tools to support and
-which not to support.

-<section>
-<title>Support More Architectures</title>
-<body>
-
-<p>
-A long-term goal of the Hardened Gentoo Project is to support all of the
-architectures that are officially supported by Gentoo. The only strong support
-that exists at the moment is for x86 and amd64.
-</p>
-
-<p>
-The hardened toolchain supports x86, amd64, ppc, ppc64, arm, ia64 and would like
-to extend support to sparc and similar architectures. With access to different
-kinds of hardware, hardened support can slowly be extended to those
-architectures as well.
-</p>
-

-</section>
-
-<section>
-<title>Expand the Hardened Team</title>
-<body>
-
-<p>
-There will always be unfinished tasks for the Hardened Team. Users who take a
-proactive approach to finding places for improvement and filling in the holes
-will be noticed and probably recruited. Current Hardened Team members will be
-responsible for training new developers to fill new roles. If you are interested
-in helping out, stop by the IRC channel and let someone know what you are
-interested in and what you will be doing about it.
-</p>
-
-<p>
-Input/peer review should always be welcome as it helps everyone out in the long
-run.

+<p>
+When you hit the mentioned error with a root crontab or an administrative
+users' crontab, but not with a regular users' crontab, then check the context of
+the crontab file:
+</p>
+
+<pre caption="Check context of the crontab file">
+~# <i>ls -Z /var/spool/cron/crontabs/root</i>
+staff_u:object_r:user_cron_spool_t /var/spool/cron/crontabs/root
+</pre>
+
+<p>
+Next, check what the default context is for the given user (in this case, root)
+when originating from the <c>crond_t</c> domain:
+</p>
+
+<pre caption="Check default context for user root">
+~# <i>getseuser root system_u:system_r:crond_t</i>
+seuser: root, level (null)
+Context 0 root:sysadm_r:cronjob_t
+Context 1 root:staff_r:cronjob_t
+</pre>
+
+<p>
+As you can see, the default context is always for the <c>root</c> SELinux user.
+However, the <path>/var/spool/cron/crontabs/root</path> file context in the
+above example is for the SELinux user staff_u. Hence, cron will not be able to
+read this file (the <c>user_cron_spool_t</c> type is a UBAC constrained one).
+</p>
+
+<p>
+To fix this, change the user of the file to root:
+</p>
+
+<pre caption="Change the SELinux user of the root crontab file">
+~# <i>chcon -u root /var/spool/cron/crontabs/root</i>

+
+<p>
+Also, try to separate types that are used by other domains as well. This way,
+the other domains can only interact with those files or resources that are
+labeled accordingly, rather than interact with a broad spectrum of files. The
+distinction that the <path>apache</path> module makes between system-provided
+content (like phpmyadmin files) and user-provided content (in the
+<path>public_html</path> directory in the users' home directories) seems (and
+is) very logical, but one could wrongly say that for Apache itself, the access
+controls are the same. Although that might be true, both types are clearly used
+in different ways so this mandates the use of different domains.
+</p>
+
+<p>
+Once you have defined those types too, start writing down the intra-domain
+permissions. Right now is a good time to look at other modules to see how they
+do things. Start with defining the accesses towards the domains.
+</p>
+
+<pre caption="Snippet from the spamassassin module">
+type spamassassin_t;
+type spamassassin_exec_t;
+application_domain(spamassassin_t, spamassassin_exec_t)
+ubac_constrained(spamassassin_t)
+</pre>
+
+<p>
+This small snippet defines many things. The first two lines just mention the new
+types (the <path>spamassassin_t</path> domain and
+<path>spamassassin_exec_t</path> type). The <c>application_domain</c> interface
+marks <path>spamassassin_t</path> as an application domain type (it gets the
+<path>application_domain_type</path> and <path>domain</path> attributes and a
+few default permissions (like allowing that it sends SIGCHLD and SIGNULL to
+init). It also marks <path>spamassassin_exec_t</path> as an applications'
+executable type (<path>application_exec_type</path> and <path>exec_type</path>
+attributes) so that it can be executed by regular users (these domains have
+execute rights against all resources that have the
+<path>application_exec_type</path> attribute set. Finally, it marks the
+<path>spamassassin_t</path> domain as a constrained domain for user-based access
+controls. In other words, if SELinux users <path>user_u</path> and
+<path>staff_u</path> launch the application in <path>spamassassin_t</path>
+domains, then the domains are segregated from each other (the intra-domain rules
+inside <path>spamassassin_t</path> are only valid for communication within the
+same SELinux user, not between SELinux users).
+</p>
+
+<p>
+Attributes are an important aspect in SELinux policy development. They make
+managing the domains easier, but you should always consider the implications
+when you add an attribute to one of your types. It usually means that a whole
+lot of permissions are suddenly granted between other domains and yours.
+</p>
+
+<p>
+Next, set the proper intra-domain permissions. For instance, allow your domain
+to read its configuration files as well as more access inside its own
+<path>/var/lib</path> location:
+</p>
+
+<pre caption="Snippet from openca module">
+allow openca_ca_t openca_etc_t:file read_file_perms;

+</pre>
+
+<p>
+The majority of work in developing SELinux policy modules is using and choosing
+the right interfaces. Having a few functions available to browse through all the
+available information is always interesting, so you might want to use the
+following function definitions (definitely not mandatory - this is only to help
+people skim through the policy definitions):
+</p>
+
+<pre caption="SELinux policy development function definitions">

+# given regular expression

+<p>
+These functions can then be used to find the information / interfaces you are

+<body>

+When working on policy modules, you'll notice that the application is trying to

+functionality. This is to be expected: many applications do not handle file

+<title>About this document...</title>
+<body>
+
+<p>
+Dealing with Mandatory Access Control is never easy. SELinux might be available
+by default with Linux, enabling it can provide serious headaches - let alone
+developing policies for it. Within Gentoo Hardened, we strive to offer a default
+policy that is flexible enough to match the requirements of most of you (our
+users) yet remain manageable by the limited number of developers that we have.
+To ensure that the policy we offer is up to date, we definitely need help from
+end users and other developers, because developing policies requires intimate
+knowledge of the products they are written for. With over several thousand
+packages, this is just not feasible for a handful of us. Hence, this Gentoo
+Hardened SELinux Development guide.
+</p>
+
+<p>
+Within this document, we will try to explain how to set up an environment ready
+to build policies yourself and provide patches to Gentoo Hardened. We also cover
+how to deal with malfunctioning domains and even how to create your own, new
+domains from scratch (if we need to). Further down, we give an overview of the
+guidelines that we try to follow during the policy developments and finally
+talk about how to properly create patches and submit them to our <uri
+link="https://bugs.gentoo.org">bugzilla</uri> service.
+</p>
+
+<p>
+For those who want to run Gentoo Hardened with their own policies, we've also
+added a chapter on just that. We know that our policy does not match everyone's
+requirements, so we definitely want to help you run your own too.

+<title>What you need to know</title>
+<body>
+
+<p>
+This document does assume prior knowledge on SELinux policies and the way the
+reference policy works. For those that need a quick recap, here are the
+highlights...
+</p>
+
+<ul>
+ <li>
+ SELinux uses <e>domains</e> and <e>types</e> to differentiate its various
+ security objects. A domain is usually referred to as the security context
+ of a process (or group of processes) whereas a type is usually referred to
+ as the label given to a particular resource (file, directory, network
+ interface, socket, network port, ...).
+ </li>
+ <li>
+ <e>SELinux policies</e> describe what interaction is allowed between a
+ domain and the other domains and types it needs to work with. If no policy
+ allows for a particular activity, then the activity is denied.
+ </li>
+ <li>
+ The structure in which policies are written are called <e>SELinux policy
+ modules</e> which contain three parts: a <e>type enforcement file</e> (with
+ suffix <path>.te</path>) that contains the intra-module permissions, an
+ <e>interface file</e> (with suffix <path>.if</path>) that contains the
+ inter-module permissions and a <e>file contexts file</e> (with suffix
+ <path>.fc</path>) that contains the file context definitions for all file
+ resources that are labeled with the type or types defined in the module
+ </li>
+ <li>
+ Inter-domain privileges must be declared through functions in the
+ <e>interface file</e> which can then be called by other modules. This
+ includes the necessary permissions to allow domain transitions
+ </li>

+<title>Setting Up Your Environment</title>
+<section>
+<title>Patching the reference policy</title>
+<body>
+
+<p>
+Gentoo Hardened builds its policy upon the <uri
+link="http://oss.tresys.com/projects/refpolicy">reference policy</uri> as
+provided by <uri link="http://www.tresys.com">Tresys</uri> and managed through
+an active <uri
+link="http://oss.tresys.com/projects/refpolicy/wiki/HowToContribute">community</uri>.
+I suggest to use two workspaces when dealing with SELinux policies for Gentoo
+Hardened: the <path>hardened</path> one for the Gentoo patched policy, and a
+<path>local</path> one in which you work and make your patches in.
+</p>
+
+<p>
+Of course, using a source control system like git can be helpful too. For now,
+Gentoo Hardened doesn't have a git repository where its policies are based from
+(yet). That might sound a bit dull, but it forces the developers to remain as
+close to upstream as possible (and contribute the changes upstream too so that
+newer releases include them automatically). You can definitely use a source
+control system yourself - the only reason we do not use it in this document is
+that it is easier to document without ;-)
+</p>
+
+<p>
+Let's create the first workspace:
+</p>
+
+<pre caption="Creating the SELinux policy workspace">
+~$ <i>mkdir dev/hardened</i>
+~$ <i>cd dev/hardened</i>
+~$ <i>ebuild /usr/portage/sec-policy/selinux-base-policy/selinux-base-policy-2.20101213-r12.ebuild compile</i>
+~$ <i>cp -r /var/tmp/portage/sec-policy/selinux-base-policy-2.20101213-r12/work/* .</i>
+~$ <i>rm -rf /var/tmp/portage/sec-policy/selinux-base-policy-2.20101213-r12</i>
+</pre>
+
+<p>
+As result, you should have two or three directories in
+<path>dev/hardened</path> called <path>refpolicy</path> and <path>strict</path>
+and/or <path>targeted</path>. The only one of interest is the
+<path>strict</path> and/or <path>targeted</path> one, depending on the policy
+type you are working with. In the remainder of the document, I'm assuming you
+work with <path>strict</path>.
+</p>
+
+<p>
+Now the <path>dev/hardened</path> workspace is patched with the Gentoo Hardened
+SELinux patches applicable to the base policy. Gentoo Hardened has two "flavors"
+of patches:
+</p>
+
+<ol>
+ <li>
+ <e>Base policy patches</e> contain the patches for the SELinux modules that
+ take part of the base policy as well as all interface patches for the
+ modules
+ </li>
+ <li>
+ <e>Module-specific patches</e> that contain the permissions affecting the
+ domains and types that are defined in a single module (for instance, all
+ interaction between <path>portage_t</path> and <path>portage_exec_t</path>
+ or even <path>portage_t</path> and <path>portage_fetch_t</path>)
+ </li>
+</ol>
+
+<p>
+The base policy patches are important to have available at all times. The
+module-specific ones can be added when you work with that particular module.
+</p>
+

+<title>A Domain Does Not Function Properly</title>
+<section>
+<title>Introduction</title>
+<body>
+
+<p>
+The most likely problem that you are hitting is that a domain does exist in
+Gentoo Hardened SELinux, but that it isn't functioning as it should. To solve
+this problem, it is adviseable to use the following sequence of investigations:
+</p>
+
+<ol>
+ <li>
+ Is it really SELinux that is restraining your system?
+ </li>
+ <li>
+ Is the problem related to wrong resource labels / security contexts?
+ </li>
+ <li>
+ Is the problem related to intra-module permissions?
+ </li>
+ <li>
+ Is the problem related to inter-module permissions?
+ </li>
+</ol>
+
+</body>
+</section>
+<section>
+<title>Check if SELinux is to blame</title>
+<body>
+
+<p>
+Make sure that the problem you are seeing is a SELinux-triggered problem. An
+easy way to find out is to run SELinux in permissive mode and try again:
+</p>
+
+<pre caption="Switching to permissive mode">
+~# <i>setenforce 0</i>
+</pre>
+
+<p>
+This only works if the problem is <e>not</e> to do with a SELinux-aware
+application (unlike <c>init</c> or <c>sudo</c> which are linked to the
+libselinux library). SELinux-aware applications might alter their behavior if
+SELinux is set on the system regardless of it running in permissive mode or not.
+A prime example is <c>vixie-cron</c> (as can be seen in <uri
+link="https://bugs.gentoo.org/show_bug.cgi?id=257111">bug #257111</uri>). But
+for applications that are not SELinux aware, this is the easiest method to find
+out if SELinux is to blame or not.
+</p>
+
+<p>
+If running your system in permissive mode works around the problem, read on. If
+it doesn't, check the regular permissions (<c>strace</c>'ing the application
+might be a good idea too).
+</p>
+
+</body>
+</section>
+<section>
+<title>Get the proper AVC denials</title>
+<body>
+
+<p>
+Assuming that we now know that SELinux is to blame, we need to make sure that we
+get the proper AVC denials. Either locate the proper denials in
+<path>/var/log/avc.log</path> (or <path>audit.log</path>) around the time that
+you encountered the issue, or run <c>tail -f /var/log/avc.log</c> and reproduce
+the problem.
+</p>
+
+<pre caption="Example denials">
+~# <i>tail -f /var/log/avc.log</i>
+Apr 22 15:03:33 www1 kernel: [16053.303739] type=1400 audit(1303477413.188:283):
+avc: denied { dac_read_search } for pid=21758 comm="rm" capability=2
+scontext=root:sysadm_r:portage_t tcontext=root:sysadm_r:portage_t
+tclass=capability
+</pre>
+
+<p>
+Analyzing the meaning of the AVC denial is covered by <uri
+link="/proj/en/hardened/selinux/selinux-handbook.xml?part=2&chap=3#avclog">Looking
+at the AVC Log</uri> in the Gentoo Hardened SELinux handbook. The denial should
+give you a pointer where to look for. However, it is possible that no denial is
+occurring, or at least no relevant ones.
+</p>
+
+<p>
+A first step to get potentially more denials is to switch the
+<c>gentoo_try_dontaudit</c> boolean off. This boolean is used by the Gentoo
+Hardened SELinux developers to hide denials which they assume are cosmetic. As
+these developers are known to have a human side (as well), they are known to
+make mistakes ;-)
+</p>
+
+<pre caption="Disabling gentoo's dontaudit statements">
+~# <i>setsebool gentoo_try_dontaudit off</i>
+</pre>
+
+<p>
+Retry getting the proper AVC denials.
+</p>
+
+<p>
+If it still doesn't work, you can disable all <e>dontaudit</e> statements:
+</p>
+
+<pre caption="Disabling all dontaudit statements">
+~# <i>semodule -R -D -B</i>
+</pre>
+
+<p>
+Retry getting the proper AVC denials.
+</p>
+
+<p>
+The moment you get the denials you are looking for, isolate them and then undo
+the changes you made earlier:
+</p>
+
+<pre caption="Resetting the auditing defaults">
+~# <i>setsebool gentoo_try_dontaudit on</i>
+~# <i>semodule -R -B</i>
+</pre>
+
+<p>
+If you still do not see any denials, then check out the <c>dmesg</c> output for
+other problems. It is possible that SELinux is not even getting to the point of
+the policy, which you will not notice by looking at the AVC denials alone.
+However, the chance of this to happen is very slim - most of the time, you'll
+find the AVC denials you are looking for.
+</p>
+
+</body>
+</section>
+<section>
+<title>Deducing the correct security contexts</title>
+<body>
+
+<p>
+The next step is to see if we are dealing with the right security contexts. This
+does require a bit of insight in how both the application (that is failing) and
+the policy relate to each other.
+</p>
+
+<p>
+Say you are having issues with SELinux (re)labeling and you notice the following
+AVC denial:
+</p>
+
+<pre caption="AVC denial for setfiles">
+Apr 16 14:39:57 testsys kernel: [ 115.778484] type=1400
+audit(1302957597.827:224): avc: denied { create } for pid=3584
+comm="setfiles" scontext=root:sysadm_r:<comment>sysadm_t</comment> tcontext=root:sysadm_r:sysadm_t
+tclass=netlink_audit_socket
+</pre>
+
+<p>
+In this case, <c>setfiles</c> is running in the <path>sysadm_t</path> domain
+even though it should run in <path>setfiles_t</path>. So check the security
+context of the <c>setfiles</c> binary as well as the transition rules:
+</p>
+
+<pre caption="Checking setfiles context and rules">
+~# <i>ls -lZ /sbin/setfiles</i>
+-rwxr-xr-x. 1 root root <comment>system_u:object_r:bin_t</comment> 26464 Apr 9 22:22 /sbin/setfiles
+~# <i>sesearch -s sysadm_t -t setfiles_t -c process -p transition -A -d</i>
+Found 1 semantic av rules:
+ allow sysadm_t setfiles_t : process transition ;
+~# <i>sesearch -s sysadm_t -t setfiles_exec_t -c file -p execute -A -d</i>
+...
+~# <i>sesearch -s setfiles_t -t setfiles_exec_t -c file -p entrypoint -A -d</i>
+...
+</pre>
+
+<p>
+In the above (forced) situation, the problem is with the security context of the
+binary - it should have been <path>setfiles_exec_t</path> instead of
+<path>bin_t</path>. Usually, entry points are named similarly (like
+<path>portage_exec_t</path> or <path>sudo_exec_t</path>). If you are not certain
+about which domain it should be, use <c>sesearch</c>
+</p>
+
+<pre caption="Using sesearch to find the entrypoint type for a domain">
+~# <i>sesearch -s setfiles_t -c file -p entrypoint -A -d</i>
+Found 1 semantic av rules:
+ allow setfiles_t setfiles_exec_t : file { ioctl ... execute entrypoint open } ;
+</pre>
+
+<p>
+The <c>sesearch</c> utility is extremely powerful to query the SELinux policy
+(which is currently in memory). I also advise you to use the <c>-C</c> switch to
+see which rules are trigged by certain SELinux booleans:
+</p>
+
+<pre caption="Looking for boolean-triggered settings">
+~# <i>sesearch -s named_t -t named_zone_t -c file -A -d -C</i>
+Found 2 semantic av rules:
+ allow named_t named_zone_t : file { ioctl read getattr lock open } ;
+DT allow named_t named_zone_t : file { ioctl read write create getattr setattr lock append unlink link rename open } ; [ named_write_master_zones ]
+</pre>
+
+<p>
+In the above example, the <path>named_t</path> domain only has write privileges
+on files labeled <path>named_zone_t</path> if the
+<path>named_write_master_zones</path> boolean is set (which it currently isn't,
+otherwise the line would stat with ET instead of DT).
+</p>
+
+<p>
+To gain a bit of insight in the various, available domains, use <c>seinfo</c>:
+</p>
+
+<pre caption="Getting a list of available domains">
+~# <i>seinfo -t | grep named</i>
+ named_var_run_t
+ named_checkconf_exec_t

+ named_log_t
+ named_exec_t
+ named_zone_t
+ named_t
+ named_cache_t
+ named_tmp_t
+</pre>
+
+<p>
+To gain a bit of insight in the (current) file context rules, use
+<c>semanage</c>:
+</p>
+
+<pre caption="Getting the list of current file context rules">
+~# <i>semanage fcontext -l | grep named</i>

+/var/run/unbound(/.*)? all files system_u:object_r:named_var_run_t
+</pre>
+
+<p>
+Most of the time, fixing domain issues is a matter of relabeling files (or
+updating the configuration to match the contexts already defined - both work).
+</p>
+
+</body>
+</section>
+<section>
+<title>Intra-module permissions are missing</title>
+<body>
+
+<p>
+It is possible that you get a denial between correct security contexts, but
+that the permission is just never granted. In this case, you can choose between
+two things:
+</p>
+
+<ol>
+ <li>
+ Enhance the module so that the particular permission is granted, or
+ </li>
+ <li>
+ Enhance the module with an additional type where the permission is granted,
+ and assign this type/label to the related resources
+ </li>
+</ol>
+
+<p>
+In both cases you will need to edit the module files (most likely the
+<path>.te</path> file), build the module, load it, perhaps even relabel the
+files or the package and retry. It is also a good idea to take a look at
+upstream (latest refpolicy repository or the repositories of Fedora and co) and
+see if they have already solved this problem or not.
+</p>
+
+<p>
+Granting additional permissions between existing domains is the easiest, but
+might introduce additional problems: if this permission is only needed in a
+particular case yet you grant it for all files and resources related to those
+domains, then you are opening up the policy beyond what is necessary. Often,
+creating an additional domain or type can be beneficial.
+</p>
+
+<p>
+A noticeable example is Portage' support for CVS/SVN/GIT ebuilds (the so-called
+live ebuilds). These ebuilds get their repository and store it in the
+<path>distfiles/svn+src</path> location, which was by default labelled
+<path>portage_ebuild_t</path> with only read-access for the
+<path>portage_sandbox_t</path> domain. However, with those live ebuilds, the
+<path>portage_sandbox_t</path> domain also needs write privileges to this
+location. Rather than allowing <path>portage_sandbox_t</path> write privileges
+to <path>portage_ebuild_t</path>, a new type was created called
+<path>portage_svnsrc_t</path> for just this location and the rights are
+transferred towards type.
+</p>
+
+</body>
+</section>
+<section>
+<title>Inter-module permissions are needed</title>
+<body>
+
+<p>
+If the solution for the problem requires permissions between modules, then you
+need to create the proper interface functions in the target domain and call
+these functions from the source domain.
+</p>
+
+<p>
+TODO extend this explanation, use a common example, like mysql_stream_connect in
+postfix.
+</p>
+
+<p>
+TODO explain that changes in the interface require rebuilds and reinstallations
+of the base (package, not only .pp file, due to includes). tell that this is the

+ During package installation, ld.so complains 'object 'libsandbox.so' from

+</title>
+<body>
+
+<p>
+During installation of a package, you might see the following error message:
+</p>
+
+<pre caption="Error message during package installation">
+>> Installing (1 of 1) net-dns/host-991529
+>>> Setting SELinux security labels
+ERROR: ld.so: object 'libsandbox.so' from LD_PRELOAD cannot be preloaded: ignored.
+</pre>
+
+<p>
+This message should <e>only</e> occur after the <e>Setting SELinux security
+labels</e> message. It happens because SELinux tells glibc to disable
+<c>LD_PRELOAD</c> (and other environment variables that are considered
+potentially harmful) during domain transitions. Here, portage calls the
+<c>setfiles</c> command (part of a SELinux installation) and as such
+transitions from portage_t to setfiles_t, which clears the environment
+variable.
+</p>
+
+<p>
+We believe that it is safer to trust the SELinux policy here (as setfiles runs
+in its own confined domain anyhow) rather than updating the policy to allow
+transitioning between portage_t to setfiles_t without clearing these
+environment variables. Note that <e>libsandbox.so is not disabled during builds
+and merges</e>, only during the activity where Portage labels the files it
+just merged.
+</p>
+
+<p>
+So the error is in our opinion cosmetic and can be ignored (but sadly not
+hidden).

+<body>
+
+<p>
+When trying to relabel a package (<c>rlpkg packagename</c>) or system (<c>rlpkg

+</p>
+
+<pre caption="rlpkg complaining about conflicting specifications">

+This is most likely caused by hard linked files. Remember, SELinux uses the
+extended attributes in the file system to store the security context of a file.
+If two separate paths point to the same file using hard links (i.e. the files
+share the same inode) then both files will have the same security context.
+</p>
+
+<p>
+The solution depends on the particular case; in order of most likely to happen
+and resolve:
+</p>
+
+<ol>
+ <li>
+ Although both files are the same, they are not used in the same context.
+ In such cases, it is recommended to remove one of the files and then copy
+ the other file back to the first (<c>rm B; cp A B</c>). This way, both
+ files have different inodes and can be labelled accordingly.
+ </li>
+ <li>
+ Both files are used for the same purpose; in this case, it might be better
+ to label the file which would not be labelled correctly (say a binary
+ somewhere in a <path>/usr/lib64</path> location) using <c>semanage</c>
+ (<c>semanage fcontext -a -t correct_domain_t /usr/lib64/path/to/file</c>)
+ </li>
+</ol>
+
+<p>
+It is also not a bad idea to report (after verifying if it hasn't been reported
+first) this on <uri link="https://bugs.gentoo.org">Gentoo's bugzilla</uri> so
+that the default policies are updated accordingly.

+
+<p>
+No, resource limits are outside the scope of an access control system. If you

+<p>

+<section id="filesystem">
+<title>Can I use SELinux with any file system?</title>
+<body>
+
+<p>
+SELinux requires access to a file's security context to operate properly.
+To do so, SELinux uses <e>extended file attributes</e> which needs to be
+properly supported by the underlying file system. If the file system supports
+extended file attributes and you have configured your kernel to enable this
+support, then SELinux will work on those file systems.
+</p>
+
+<p>
+General Linux file systems, such as ext2, ext3, ext4, jfs, xfs and btrfs
+support extended attributes (but don't forget to enable it in the kernel
+configuration) as well as tmpfs (for instance used by udev). If your file
+system collection is limited to this set, then you should have no issues.
+</p>
+
+<p>
+Ancillary file systems such as vfat and iso9660 are supported too, but with
+an important caveat: all files in each file system will have the same SELinux
+security context information since these file systems do not support extended
+file attributes.
+</p>
+
+<p>
+Network file systems can be supported in the same manner as ancillary file
+systems (all files share the same security context). However, some development

+The easiest way is to use the <c>setenforce</c> command. With <c>setenforce
+0</c> you tell SELinux to run in permissive mode. Similarly, with
+<c>setenforce 1</c> you tell SELinux to run in enforcing mode.
+</p>
+
+<p>
+You can also add a kernel option <c>enforcing=0</c> or <c>enforcing=1</c>
+in the bootloader configuration (or during the startup routine of the system).
+This allows you to run SELinux in permissive or enforcing mode from the start
+of the system.
+</p>
+
+<p>
+The default state of the system is kept in <path>/etc/selinux/config</path>.

+<section id="disable_selinux">
+<title>How do I disable SELinux completely?</title>
+<body>
+
+<p>
+It might be possible that running SELinux in permissive mode is not sufficient
+to properly fix any issue you have. To disable SELinux completely, you need to
+edit <path>/etc/selinux/config</path> and set <c>SELINUX=disabled</c>. Next,
+reboot your system.
+</p>
+
+<impo>
+When you have been running your system with SELinux disabled, you must boot
+in permissive mode first and relabel your entire file system. Activities ran
+while SELinux was disabled might have created new files or removed the labels
+from existing files, causing these files to be available with no security
+context.

+<p>
+This is nothing to worry about (and perfectly normal).

+</p>
+
+<pre caption="Error message from emerge on the SELinux module">
+!!! SELinux module not found. Please verify that it was installed.
+</pre>
+
+<p>
+This indicates that the portage SELinux module is missing or damaged. Recent
+Portage versions provide this module out-of-the-box, but the security contexts
+of the necessary files might be wrong on your system. Try relabelling the files
+of the portage package:

+When running emerge, the following error is shown:
+</p>
+
+<pre caption="Emerge error on loadpolicy">
+FEATURES variable contains unknown value(s): loadpolicy
+</pre>
+
+<p>
+This is a remnant of the older SELinux policy module set where policy packages
+might require this FEATURE to be available. Although the more recent packages
+do not support this FEATURE value anymore, these are still in the ~arch phase
+so the current SELinux profile still offers this value. Portage however already
+knows that this FEATURE is not supported anymore and complains.
+</p>
+
+<p>
+We recommend you to use the ~arch versions of all packages in the sec-policy
+category, and set <c>FEATURES="-loadpolicy"</c> to disable this (cosmetic)
+error.
+</p>
+
+<p>
+Once the newer policy modules are stabilized, the SELinux profile will be updated
+to remove this setting.
