<p >This document describes the processes through which sensitive security relevant bugs can be responsibly disclosed to the libcgroup project and how the project maintainers should handle these reports. Just like the other libcgroup process documents, this document should be treated as a guiding document and not a hard, unyielding set of regulations; the bug reporters and project maintainers are encouraged to work together to address the issues as best they can, in a manner which works best for all parties involved.</p>

+<h2><a class="anchor" id="autotoc_md29"></a>
Reporting Problems</h2>
<p >Problems with the libcgroup library that are not suitable for immediate public disclosure should be emailed to the current libcgroup maintainers; see below. We typically request at most a 90 day time period to address the issue before it is made public, but we will make every effort to address the issue as quickly as possible and shorten the disclosure window.</p>

+<h2><a class="anchor" id="autotoc_md30"></a>
Resolving Sensitive Security Issues</h2>
<p >Upon disclosure of a bug, the maintainers should work together to investigate the problem and decide on a solution. In order to prevent an early disclosure of the problem, those working on the solution should do so privately and outside of the traditional libcgroup development practices. One possible solution to this is to leverage the GitHub "Security" functionality to create a private development fork that can be shared among the maintainers, and optionally the reporter. A placeholder GitHub issue may be created, but details should remain extremely limited until such time as the problem has been fixed and responsibly disclosed. If a CVE, or other tag, has been assigned to the problem, the GitHub issue title should include the vulnerability tag once the problem has been disclosed.</p>
-<h2><a class="anchor" id="autotoc_md28"></a>
+<h2><a class="anchor" id="autotoc_md31"></a>
Public Disclosure</h2>
<p >Whenever possible, responsible reporting and patching practices should be followed, including notification to the linux-distros and oss-security mailing lists.</p>

The <code>-c</code> flag instructs libcgroup to create a systemd scope; libcgroup then instructs systemd that this hierarchy is delegated, i.e. it is to be managed by another process and <em>not</em> by systemd. The <code>-S</code> flag notifies libcgroup that we want <code>mycompany.scope/database.slice</code> to be the default base path in libcgroup; this will significantly help in reducing typing in follow-on commands. The <code>-g</code> flag tells libcgroup to create a cgroup named <code>mycompany.slice/database.scope</code> and enable the cpu and memory controllers within it.</p>
+<details >
+<p ><summary>Problems during this step?</summary></p>
+<p >Systemd should automatically remove scopes with no active processes running within them. So, the first step would be to kill any processes in the scope, wait to see if systemd removes the scope, and then try the <code>cgcreate</code> operation again.</p><ul>
+<li><p class="startli">Remove all processes in the scope ``` $ for PID in $(cgget -nvb -r cgroup.procs mycompany.slice/database.scope); do sudo kill -9 $PID;done ```</p>
+<p class="startli">The above command could be simplified as <code>for PID in $(cgget -nv -r cgroup.procs /); do sudo kill -9 $PID;done</code>, but introduces some risk. If there is a typo or the default scope path isn't set, then unconditionally killing processes in <code>/</code> could be catastrophic.</p>
+</li>
+</ul>
+<p >Sometimes systemd's internal list of scopes gets out of sync with the filesystem. You can purge the <code>database.scope</code> from its list by running the following commands</p><ul>
+<li>Remove <code>database.scope</code> from systemd's internal list ``` sudo systemctl kill database.scope sudo systemctl stop database.scope ``` </li>
+</ul>

+<div class="line">cgcreate: can't create cgroup mycompany.slice/database.scope/high-priority: Operation not supported</div>
+</div><!-- fragment --><p class="startli">But... but... I did everything right. Why can't I create the <code>high-priority</code> child cgroup? This operation failed due to the <a href="https://systemd.io/CGROUP_DELEGATION/">no-processes-in-inner-nodes</a> rule. Since a process, <code>libcgroup_systemd_idle_thread</code>, resides in <code>database.scope</code>, we are subject to the no-process-in-inner-nodes rule. The kernel will let us create a child cgroup, but it will fail when we try to enable controllers in <code>database.scope</code>'s <code>cgroup.subtree_control</code> file. There are a few different ways to solve this failure; the easiest is probably to create a temporary cgroup under <code>database.scope</code> and move the <code>libcgroup_systemd_idle_thread</code> to this temporary cgroup. This allows <code>database.scope</code> to operate as a legal inner node, and we can then create the entire hierarchy.</p><ol type="a">
+<li><p class="startli">Temporarily disable the cpu and memory controllers at the scope level </p><div class="fragment"><div class="line">sudo cgset -r cgroup.subtree_control="-cpu -memory" /</div>
+</div><!-- fragment --><p class="startli">Since we informed libcgroup that <code>mycompany.slice/database.scope</code> is the default path, we can use <code>/</code>. Otherwise, we would have had to specify the entire path. This pattern continues throughout this example.</p>
