NAMEnamespace_init_selinux − Security Enhanced Linux Policy for the namespace_init processes

DESCRIPTIONSecurity-Enhanced Linux secures the namespace_init processes via flexible mandatory access control. The namespace_init processes execute with the namespace_init_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 namespace_init_t

ENTRYPOINTSThe namespace_init_t SELinux type can be entered via the namespace_init_exec_t file type. The default entrypoint paths for the namespace_init_t domain are the following: /etc/security/namespace.init, /etc/security/namespace.d(/.*)?

PROCESS TYPESSELinux 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 namespace_init policy is very flexible allowing users to setup their namespace_init processes in as secure a method as possible. The following process types are defined for namespace_init: namespace_init_tNote: semanage permissive -a namespace_init_t can be used to make the process type namespace_init_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANSSELinux policy is customizable based on least access required. namespace_init policy is extremely flexible and has several booleans that allow you to manipulate the policy and run namespace_init with the tightest access possible. 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 If you want to enable polyinstantiated directory support, you must turn on the polyinstantiation_enabled boolean. Disabled by default. setsebool -P polyinstantiation_enabled 1

MANAGED FILESThe SELinux process type namespace_init_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.
security_t /selinux

user_home_type all user home files

FILE CONTEXTSSELinux 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 namespace_init policy is very flexible allowing users to setup their namespace_init processes in as secure a method as possible. The following file types are defined for namespace_init: namespace_init_exec_t- Set files with the namespace_init_exec_t type, if you want to transition an executable to the namespace_init_t domain.
Paths: /etc/security/namespace.init, /etc/security/namespace.d(/.*)? 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.

COMMANDSsemanage 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.
