These types are treated as special by restorecon, in that they won’t usually be relabeled by restorecon unless the extra -F flag is passed. This is because these types are either associated with categories (as mentioned in Multi-Category Security), or they are user content types that the user is allowed to customize. In some cases it might also be the case that the user has moved files with a type that is listed in /etc/selinux/targeted/contexts/customizable_types. To relabel content that has a customizable type associated with it, run restorecon as above with the extra flag:.

Since NGINX itself is a HTTPD domain, it should dominate all backend servers, so if we have categories c0 through c5 available for HTTPD domains we would want to run NGINX as system_u:system_r:httpd_t:s0-s0:c0. An example use of Multi-Category Security could be using NGINX with multiple vhosts that connect to backend servers that are also running as httpd domains (e. C5, so it could connect to the upstream servers. Normally these instances of the backend servers would be able to modify and manage each others domains simply due to type-enforcement rules. Each backend server would run with a single category within c0-c5, and a context such as system_u:system_r:httpd_t:s0-s0:c1. If they’re associated with categories, they can only do so if one backend server dominates the other.

This article is intended to give an overview of working with SELinux for users new to SELinux. SELinux is installed and enabled by default, and for most users it will function without issue affording an enhanced level of security. SELinux is suitable for all classes of installation including servers, workstations, desktops and laptops.

The identifier in square brackets is the name of the boolean that would allow this access, and the DT prefixing the rule indiciates it is currently disabled. This was an easy one. We can turn this on using setsebool -P antivirus_use_jit=1, but we might also want to inspect exactly what this boolean is allowing first, and the same sesearch utility lets us do that:.

Using Apache as an example, suppose you want to change the DocumentRoot to serve web pages from a location other than the default /var/www/html/ directory. Assume we create a directory (or maybe a mount point) at /html/ and create an index.

This is based upon user:role:type:mls. Within the default targeted policy, type is the important field used to implement Type Enforcement, in this case httpd_sys_content_t. In our example above, user:role:type fields are displayed and mls is hidden.

The usual operation for this is setenforce 0, however that puts all domains on the system into permissive mode rather than just the domain of the process encountering an issue. When a program is being denied an operation repeatedly by SELinux, it is sometimes easier to continue debugging while in permissive mode. To avoid this, SELinux supports the concept of permissive types, allowing the administrator to put just a single domain into permissive mode rather than the entire system.

Quite often when encountering SELinux denials it will be the case that the operation that is denied is actually allowed in policy, but wasn’t permitted due to a file not being labeled correctly or a process not transitioning to the correct domain. Issues like these are best reported to the policy authors and maintainers, but are not impossible to figure out using the analysis tools provided by the setools-console package.
