🌸 NAME 🌸

okay so bestie, welcome to the portreserve_selinux(8) page — manual name is literally portreserve_selinux, section 8, and the header vibe is SELinux Policy portreserve. this is all about the Security Enhanced Linux Policy for the portreserve processes. yes queen, we're doing SELinux lore today 💅✨

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the portreserve processes via flexible mandatory access control. iconic, honestly.

The portreserve processes execute with the portreserve_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 portreserve_t

🚪 ENTRYPOINTS 🚪

The portreserve_t SELinux type can be entered via the portreserve_exec_t file type. slay.

The default entrypoint paths for the portreserve_t domain are literally the following:

/usr/bin/portreserve

🧬 PROCESS TYPES 🧬

SELinux defines process types (domains) for each process running on the system. like, every process gets a vibe check, and the vibe is its domain ✨

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

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

The following process types are defined for portreserve:

  • portreserve_t
Note: semanage permissive -a portreserve_t can be used to make the process type portreserve_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so it's not a free pass, bestie, it's just a softer no 😭

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. portreserve policy is extremely flexible and has several booleans that allow you to manipulate the policy and run portreserve with the tightest access possible. tune it, don't run it wide open 🫶

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

📁 MANAGED FILES 📁

The SELinux process type portreserve_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. DAC said what it said 💅

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. yes, files have labels, it's a whole thing 🎀

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the portreserve. 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 portreserve_exec_t '/srv/portreserve/content(/.*)?'
restorecon -R -v /srv/myportreserve_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🙈

The following file types are defined for portreserve:

  • portreserve_etc_t — Set files with the portreserve_etc_t type, if you want to store portreserve files in the /etc directories.
  • portreserve_exec_t — Set files with the portreserve_exec_t type, if you want to transition an executable to the portreserve_t domain.
  • portreserve_initrc_exec_t — Set files with the portreserve_initrc_exec_t type, if you want to transition an executable to the portreserve_initrc_t domain.
  • portreserve_var_run_t — Set files with the portreserve_var_run_t type, if you want to store the portreserve 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, know the difference bestie 💅

🛠️ 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. ooo a GUI, fancy ✨
