NAME¶

mediawiki_script_selinux - Security Enhanced Linux Policy for the mediawiki_script processes

DESCRIPTION¶

Security-Enhanced Linux secures the mediawiki_script processes via flexible mandatory access control.

The mediawiki_script processes execute with the mediawiki_script_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep mediawiki_script_t

ENTRYPOINTS¶

The mediawiki_script_t SELinux type can be entered via the mediawiki_script_exec_t, mediawiki_script_exec_t file types.

The default entrypoint paths for the mediawiki_script_t domain are the following:

/usr/lib/mediawiki/math/texvc, /usr/lib/mediawiki/math/texvc_tes, /usr/lib/mediawiki/math/texvc_tex, /usr/lib/mediawiki/math/texvc, /usr/lib/mediawiki/math/texvc_tes, /usr/lib/mediawiki/math/texvc_tex

PROCESS TYPES¶

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to ps

Policy governs the access confined processes have to files. SELinux mediawiki_script policy is very flexible allowing users to setup their mediawiki_script processes in as secure a method as possible.

The following process types are defined for mediawiki_script:

mediawiki_script_t

Note: semanage permissive -a mediawiki_script_t can be used to make the process type mediawiki_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS¶

SELinux policy is customizable based on least access required. mediawiki_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mediawiki_script with the tightest access possible.

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to allow httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default.

setsebool -P httpd_enable_cgi 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

MANAGED FILES¶

The SELinux process type mediawiki_script_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

mediawiki_rw_content_t

/var/www/wiki[0-9]?(/.*)?

mediawiki_tmp_t

FILE CONTEXTS¶

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls

Policy governs the access confined processes have to these files. SELinux mediawiki_script policy is very flexible allowing users to setup their mediawiki_script processes in as secure a method as possible.

The following file types are defined for mediawiki_script:

mediawiki_script_exec_t

- Set files with the mediawiki_script_exec_t type, if you want to transition an executable to the mediawiki_script_t domain.

Paths:

/usr/lib/mediawiki/math/texvc, /usr/lib/mediawiki/math/texvc_tes, /usr/lib/mediawiki/math/texvc_tex

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

COMMANDS¶

semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove policy modules.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
