💅 prelude_..._selinux(8) — SELinux Policy for prelude_correlator 💅

Bestie, this is the manual page for prelude_correlator_selinux — aka the SELinux Policy for the prelude_correlator processes. The manual name is literally SELinux Policy prelude_correlator, and we're about to go through it together, no skips. 🫶

🌸 NAME 🌸

prelude_correlator_selinux — Security Enhanced Linux Policy for the prelude_correlator processes.

✨ DESCRIPTION ✨

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

The prelude_correlator processes execute with the prelude_correlator_t SELinux type. Wanna check if you've got these processes running? Run the ps command with the -Z qualifier.

For example (because examples slay):

ps -eZ | grep prelude_correlator_t

🚪 ENTRYPOINTS 🚪

The prelude_correlator_t SELinux type can be entered via the prelude_correlator_exec_t file type.

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

/usr/bin/prelude-correlator

👑 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. The SELinux prelude_correlator policy is very flexible, allowing users to set up their prelude_correlator processes in as secure a method as possible.

The following process types are defined for prelude_correlator:

• prelude_correlator_t

Note: semanage permissive -a prelude_correlator_t can be used to make the process type prelude_correlator_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. The prelude_correlator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run prelude_correlator with the tightest access possible.

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 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 allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

🗂️ MANAGED FILES 🗂️

The SELinux process type prelude_correlator_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions.

• cluster_conf_t
  • /etc/cluster(/.*)?
• cluster_var_lib_t
  • /var/lib/pcsd(/.*)?
  • /var/lib/cluster(/.*)?
  • /var/lib/openais(/.*)?
  • /var/lib/pengine(/.*)?
  • /var/lib/corosync(/.*)?
  • /usr/lib/heartbeat(/.*)?
  • /var/lib/heartbeat(/.*)?
  • /var/lib/pacemaker(/.*)?
• cluster_var_run_t
  • /run/crm(/.*)?
  • /run/cman_.*
  • /run/rsctmp(/.*)?
  • /run/aisexec.*
  • /run/heartbeat(/.*)?
  • /run/pcsd-ruby.socket
  • /run/corosync-qnetd(/.*)?
  • /run/corosync-qdevice(/.*)?
  • /run/pcsd.socket
  • /run/corosync.pid
  • /run/cpglockd.pid
  • /run/rgmanager.pid
  • /run/cluster/rgmanager.sk
• prelude_spool_t
  • /var/spool/prelude(/.*)?
  • /var/spool/prelude-manager(/.*)?

  • /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
  • /
  • /initrd
  • /var/lib/ntp

🏷️ 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. The SELinux prelude_correlator policy is very flexible, allowing users to set up their prelude_correlator processes in as secure a method as possible.

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for prelude_correlator. If you wanted to store files with these types in 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 prelude_correlator_exec_t
'/srv/prelude_correlator/content(/.*)?'
restorecon -R -v /srv/myprelude_correlator_content

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

The following file types are defined for prelude_correlator:

• prelude_correlator_config_t — Set files with the prelude_correlator_config_t type if you want to treat the files as prelude correlator configuration data, usually stored under the /etc directory.
• prelude_correlator_exec_t — Set files with the prelude_correlator_exec_t type if you want to transition an executable to the prelude_correlator_t domain.

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.
