Basic infrastructure

struct cgroup* is the heart of libcgroup API. The structure is opaque to applications, all access to the structure is through appropriate functions.

-

The most important information is that one struct cgroup* can represent zero, one or more real control groups in kernel. The struct cgroup* is identified by name of the group, which must be set by cgroup_new_cgroup(). Multiple controllers (aka subsystems) can be attached to one struct cgroup* using cgroup_add_controller(). These controllers can belong to different hierarchies.

-

This approach is different to the one in the Linux kernel - a control group must be part of exactly one hierarchy there. In libcgroup, a group can be part of multiple hierarchies, as long as the group name is the same.

Multiple controllers (aka subsystems) can be attached to one struct cgroup* using cgroup_add_controller(). These controllers can belong to different hierarchies.

+

This approach is different to the one in the Linux kernel - a control group must be part of exactly one hierarchy there. In libcgroup, a group can be part of multiple hierarchies, as long as the group name is the same.

Example:
Let there be following control groups:
cpu,cpuacct:/
cpu,cpuacct:/foo
cpu,cpuacct:/bar
freezer:/
freezer:/foo
I.e. there is cpu and cpuacct controller mounted together in one hierarchy, with foo and bar groups. In addition, freezer is mounted as separate hierarchy, with only one foo group.
-
Following code creates struct cgroup* structure, which represents one group cpu,cpuacct:/foo:
struct cgroup *foo = cgroup_new_cgroup("foo");
-
cgroup_add_controller(foo, "cpu");
-
cgroup_new_cgroup
struct cgroup * cgroup_new_cgroup(const char *name)
Definition: wrapper.c:44
-
cgroup_add_controller
struct cgroup_controller * cgroup_add_controller(struct cgroup *cgroup, const char *name)
Definition: wrapper.c:56
+
Following code creates struct cgroup* structure, which represents one group cpu,cpuacct:/foo:
struct cgroup *foo = cgroup_new_cgroup("foo");
+
cgroup_add_controller(foo, "cpu");
+
cgroup_add_controller
struct cgroup_controller * cgroup_add_controller(struct cgroup *cgroup, const char *name)

+
cgroup_new_cgroup
struct cgroup * cgroup_new_cgroup(const char *name)
Definition: wrapper.c:44
cgroup
Definition: libcgroup-internal.h:114
Now, you can call e.g. cgroup_delete_cgroup() and the group is deleted from the hierarchy. You can note that it's enough to add only one controller to the group to fully identify a group in cpu,cpuacct hierarchy.
-
Following code creates struct cgroup* structure, which represents two groups, cpu,cpuacct:/foo and freezer:/foo:
struct cgroup *foo = cgroup_new_cgroup("foo");
-
cgroup_add_controller(foo, "cpu");
-
cgroup_add_controller(foo, "freezer");
+
Following code creates struct cgroup* structure, which represents two groups, cpu,cpuacct:/foo and freezer:/foo:
struct cgroup *foo = cgroup_new_cgroup("foo");
+
cgroup_add_controller(foo, "cpu");
+
cgroup_add_controller(foo, "freezer");
Now, if you call e.g. cgroup_delete_cgroup(), the group gets deleted from both hierarchies.
Todo:
add some propaganda what's so great on this approach... I personally think it is broken and confusing (see TODOs below).

So-called iterators are a code pattern to retrieve various data from libcgroup in distinct chunks, for example when an application needs to read list of groups in a hierarchy, it uses iterator to get one group at a time. Iterator is opaque to the application, the application sees only void* handle pointer, which is managed internally by libcgroup. Each iterator provides at least these functions:

    So-called iterators are a code pattern to retrieve various data from libcgroup in distinct chunks, for example when an application needs to read list of groups in a hierarchy, it uses iterator to get one group at a time. Iterator is opaque to the application, the application sees only void* handle pointer, which is managed internally by libcgroup. Each iterator provides at least these functions:

    • int iterator_name_begin(void **handle, my_type *item)
      • Initialize the iterator, store pointer to it into the handle.
      • Return the first element in the iterator, let's say it's my_type.

Logging

Libcgroup allows applications to register a callback function which libcgroup will call when it wants to log something. Each log message has associated a log level. As described in previous chapter, most libcgroup functions return an error code, which described root cause of the failure and log messages might provide further details about these failures and other notable events.

Libcgroup allows applications to register a callback function which libcgroup will call when it wants to log something. Each log message has associated a log level. As described in previous chapter, most libcgroup functions return an error code, which described root cause of the failure and log messages might provide further details about these failures and other notable events.

The logging callback can be set at any time, but setting the callback before any other libcgroup function (including cgroup_init()) is highly recommended. If no logger is set before cgroup_init() is called, default logger is automatically set, logging CGROUP_LOG_ERROR messages to stdout.
Setting log level
Some of the functions below set the log level as integer. Application can set directly a value of enum cgroup_log_level or use value -1 to set the log level automatically. In this case, libcgroup inspects environment variable CGROUP_LOGLEVEL if it is set and contains any of these values: ERROR, WARNING, INFO, DEBUG or integer number representing value from enum cgroup_log_level. If CGROUP_LOGLEVEL is not set or its value is not valid, CGROUP_LOG_ERROR is set as default log level.

Following short example shows custom libcgroup logger sending all log messages to stderr:

 You can invoke only the functional tests with the following commands: 
# cd tests/ftests

 Note that the functional tests can be run within a container or directly on your system. For the containerized tests, libcgroup utilizes LXC/LXD containers. If your system or distro doesn't support LXC/LXD, you can utilize the continuous integration infrastructure to test your changes. A successful continuous integration run is required for each pull request.

Many tests can also be run outside of a container. Use caution with these tests though, as they will modify your host's cgroup hierarchy. This could significantly and negatively affect your system.

 After the run is complete, the ftests.sh.log and ftests-nocontainer.sh.log contain the full debug log for each run.

 

 Add New Tests for New Functionality

-
The libcgroup project utilizes automated tests, code coverage, and continuous integration to maintain a high level of code quality. Any pull requests that add functionality or significantly change existing code should include additional tests to verify the proper operation of the proposed changes. Note that functional tests are preferred over unit tests.

-
The continuous integration tools run the automated tests and automatically gather code coverage numbers. Pull requests that cause the code coverage numbers to decrease are strongly discouraged.

 Explain Your Work

-
At the top of every patch you should include a description of the problem you are trying to solve, how you solved it, and why you chose the solution you implemented. If you are submitting a bug fix, it is also incredibly helpful if you can describe/include a reproducer for the problem in the description as well as instructions on how to test for the bug and verify that it has been fixed.

 Sign Your Work

The sign-off is a simple line at the end of the patch description, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The "Developer's Certificate of Origin" pledge is taken from the Linux Kernel and the rules are pretty simple:

libcgroup was initially hosted on Sourceforge and at that time only accepted patches via the mailing list. In 2018, libcgroup was moved to github and now accepts patches via email or github pull request. Over time the libcgroup project will likely fully transition to gitub pull requests and issues.

Depending on how you decided to work with the libcgroup code base and what tools you are using there are different ways to generate your patch(es). However, regardless of what tools you use, you should always generate your patches using the "unified" diff/patch format and the patches should always apply to the libcgroup source tree using the following command from the top directory of the libcgroup sources: 
# patch -p1 < changes.patch

# patch -p1 < changes.patch
 
 If you are not using git, stacked git (stgit), or some other tool which can generate patch files for you automatically, you may find the following command helpful in generating patches, where "libcgroup.orig/" is the unmodified source code directory and "libcgroup/" is the source code directory with your changes: 
# diff -purN libcgroup.orig/ libcgroup/
 
 When in doubt please generate your patch and try applying it to an unmodified copy of the libcgroup sources; if it fails for you, it will fail for the rest of us.

-
Finally, you will need to email your patches to the mailing list so they can be reviewed and potentially merged into the main libcgroup repository. When sending patches to the mailing list it is important to send your email in text form, no HTML mail please, and ensure that your email client does not mangle your patches. It should be possible to save your raw email to disk and apply it directly to the libcgroup source code; if that fails then you likely have a problem with your email client. When in doubt try a test first by sending yourself an email with your patch and attempting to apply the emailed patch to the libcgrup repository; if it fails for you, it will fail for the rest of us trying to test your patch and include it in the main libcgroup repository.

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.

Reporting Problems

-

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.

Resolving Sensitive Security Issues

-

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.
