💅 ricci_selinux(8) — the ricci girlies' guide to SELinux

okay so this is the manual page for ricci_selinux (like, the ricci_selinux(8) one, from the ricci policy section, bestie ✨) — Security Enhanced Linux Policy for the ricci processes. yes it's a mouthful. no we're not skipping it. let's go 💖

🌸 NAME 🌸

ricci_selinux — Security Enhanced Linux Policy for the ricci processes. that's it. that's the whole name section. she's concise 💅

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the ricci processes via flexible mandatory access control. like, MAC but not the makeup kind (well, kinda the makeup kind — it's a whole look for your processes 🎀).

The ricci processes execute with the ricci_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 ricci_t

literally just vibe-check your processes, iykyk 🦋

🚪 ENTRYPOINTS 🚪

The ricci_t SELinux type can be entered via the bin_t, ricci_exec_t, usr_t file types.

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

All executables with the default executable label, usually stored in /usr/bin and /usr/sbin. Then, bestie, here's the full list (yes, all of it, don't skip 👀):

  • /usr/bin/ricci
  • /opt/.*
  • /usr/.*
  • /hana(/.*)?
  • /emul/.*
  • /export(/.*)?
  • /ostree(/.*)?
  • /usr/doc(/.*)?/lib(/.*)?
  • /usr/inclu.e(/.*)?
  • /usr/share/rpm(/.*)?
  • /usr/share/doc(/.*)?/README.*
  • /usr/lib/modules(/.*)/vmlinuz
  • /usr/lib/modules(/.*)/sysctl.conf
  • /usr/lib/modules(/.*)/initramfs.img
  • /usr/lib/sysimage(/.*)?
  • /usr/lib/ostree-boot(/.*)?
  • /opt
  • /usr
  • /emul

👑 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 ricci policy is very flexible, allowing users to setup their ricci processes in as secure a method as possible. slay 🔥

The following process types are defined for ricci:

  • ricci_t
  • ricci_modcluster_t
  • ricci_modclusterd_t
  • ricci_modlog_t
  • ricci_modrpm_t
  • ricci_modservice_t
  • ricci_modstorage_t
Note: semanage permissive -a ricci_t can be used to make the process type ricci_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she's off the hook but the receipts still exist 💀

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. ricci policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ricci 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 system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

not me listing booleans like a playlist 🎧💜

🦋 PORT TYPES 🦋

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for ricci:

  • ricci_modcluster_port_t — Default Defined Ports: tcp 16851, udp 16851
  • ricci_port_t — Default Defined Ports: tcp 11111, udp 11111

ports are literally her love language ⭐

📁 MANAGED FILES 📁

The SELinux process type ricci_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. SELinux said "she can come in" but DAC said "check the guest list first" 🙈

🌈 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 ricci policy is very flexible, allowing users to setup their ricci processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the ricci. 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. periodt 💅

semanage fcontext -a -t ricci_exec_t '/srv/ricci/content(/.*)?'
restorecon -R -v /srv/myricci_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🫶

The following file types are defined for ricci:

  • ricci_exec_t — Set files with the ricci_exec_t type, if you want to transition an executable to the ricci_t domain.
  • ricci_initrc_exec_t — Set files with the ricci_initrc_exec_t type, if you want to transition an executable to the ricci_initrc_t domain.
  • ricci_modcluster_exec_t — Set files with the ricci_modcluster_exec_t type, if you want to transition an executable to the ricci_modcluster_t domain.
  • ricci_modcluster_var_lib_t — Set files with the ricci_modcluster_var_lib_t type, if you want to store the ricci modcluster files under the /var/lib directory.
  • ricci_modcluster_var_log_t — Set files with the ricci_modcluster_var_log_t type, if you want to treat the data as ricci modcluster var log data, usually stored under the /var/log directory.
  • ricci_modcluster_var_run_t — Set files with the ricci_modcluster_var_run_t type, if you want to store the ricci modcluster files under the /run or /var/run directory.
    • Paths: /run/clumond.sock, /run/modclusterd.pid
  • ricci_modclusterd_exec_t — Set files with the ricci_modclusterd_exec_t type, if you want to transition an executable to the ricci_modclusterd_t domain.
  • ricci_modclusterd_tmpfs_t — Set files with the ricci_modclusterd_tmpfs_t type, if you want to store ricci modclusterd files on a tmpfs file system.
  • ricci_modlog_exec_t — Set files with the ricci_modlog_exec_t type, if you want to transition an executable to the ricci_modlog_t domain.
  • ricci_modrpm_exec_t — Set files with the ricci_modrpm_exec_t type, if you want to transition an executable to the ricci_modrpm_t domain.
  • ricci_modservice_exec_t — Set files with the ricci_modservice_exec_t type, if you want to transition an executable to the ricci_modservice_t domain.
  • ricci_modstorage_exec_t — Set files with the ricci_modstorage_exec_t type, if you want to transition an executable to the ricci_modstorage_t domain.
  • ricci_modstorage_lock_t — Set files with the ricci_modstorage_lock_t type, if you want to treat the files as ricci modstorage lock data, stored under the /var/lock directory.
  • ricci_tmp_t — Set files with the ricci_tmp_t type, if you want to store ricci temporary files in the /tmp directories.
  • ricci_var_lib_t — Set files with the ricci_var_lib_t type, if you want to store the ricci files under the /var/lib directory.
  • ricci_var_log_t — Set files with the ricci_var_log_t type, if you want to treat the data as ricci var log data, usually stored under the /var/log directory.
  • ricci_var_run_t — Set files with the ricci_var_run_t type, if you want to store the ricci files under the /run or /var/run directory.
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. temporary vs permanent, bestie — know the difference 😭

🛠️ 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 port can also be used to manipulate the port definitions.

semanage boolean can also be used to manipulate the booleans.

system-config-selinux is a GUI tool available to customize SELinux policy settings. yes bestie, a GUI. for the mouse girlies 🖱️💖
