setfiles_selinux - Man Page

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

The setfiles processes execute with the setfiles_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 setfiles_t

The setfiles_t SELinux type can be entered via the setfiles_exec_t file type.

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

/usr/bin/setfiles.*, /usr/bin/restorecon

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 psbP

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

The following process types are defined for setfiles:

setfiles_t, setfiles_mac_t

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

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

If you want to allow system cron jobs to relabel filesystem for restoring file contexts, you must turn on the cron_can_relabel boolean. Disabled by default.

setsebool -P cron_can_relabel 1

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 enable polyinstantiated directory support, you must turn on the polyinstantiation_enabled boolean. Disabled by default.

setsebool -P polyinstantiation_enabled 1

The SELinux process type setfiles_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

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 lsbP

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the setfiles, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t setfiles_exec_t '/srv/setfiles/content(/.*)?'
restorecon -R -v /srv/mysetfiles_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for setfiles:

setfiles_exec_t

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

Paths:

/usr/bin/setfiles.*, /usr/bin/restorecon

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.

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.
