💅 systemd_bootchart_selinux(8) 💅

okay bestie, welcome to the SELinux policy page for the systemd_bootchart processes — yes, the manual name is systemd_bootchart_selinux(8), and it's giving very “security policy but make it cute” energy ✨

💖 NAME 💖

systemd_bootchart_selinux — the Security Enhanced Linux Policy for the systemd_bootchart processes 🎀

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the systemd_bootchart processes via flexible mandatory access control. no cap, that's the whole vibe 🔥

The systemd_bootchart processes execute with the systemd_bootchart_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 systemd_bootchart_t

🦋 ENTRYPOINTS 🦋

The systemd_bootchart_t SELinux type can be entered via the systemd_bootchart_exec_t file type. that's the doorway, bestie 🚪✨

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

/usr/lib/systemd/systemd-bootchart

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. very main-character energy of it 💅

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

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

The following process types are defined for systemd_bootchart:

  • systemd_bootchart_t
Note: semanage permissive -a systemd_bootchart_t can be used to make the process type systemd_bootchart_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so yes, the drama is still logged 💀

🍓 BOOLEANS 🍓

SELinux policy is customizable based on least access required. systemd_bootchart policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_bootchart with the tightest access possible. tightest access = bestie behavior 🔐✨

  • daemons_dontaudit_scheduling — 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
  • fips_mode — 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
  • nis_enabled — 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 systemd_bootchart_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. yes, DAC still gets a say, bestie 😭

🌈 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. peek the label, bestie 👀

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

🎀 STANDARD FILE CONTEXT 🎀

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

The following file types are defined for systemd_bootchart:

💅 systemd_bootchart_exec_t

  • Set files with the systemd_bootchart_exec_t type, if you want to transition an executable to the systemd_bootchart_t domain.

💅 systemd_bootchart_tmpfs_t

  • Set files with the systemd_bootchart_tmpfs_t type, if you want to store systemd bootchart files on a tmpfs file system.

💅 systemd_bootchart_unit_file_t

  • Set files with the systemd_bootchart_unit_file_t type, if you want to treat the files as systemd bootchart unit content.

💅 systemd_bootchart_var_run_t

  • Set files with the systemd_bootchart_var_run_t type, if you want to store the systemd bootchart 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 labels = not the same thing, 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.
