💖 systemd_tpm2_generator_selinux — SELinux Policy for the systemd_tpm2_generator processes 💖

okay so bestie, this is the <pink>systemd_tpm2_generator_selinux</pink> page from the SELinux Policy manual — yes, the manpage is literally named that, we love a descriptive queen 💅

✨ NAME ✨

systemd_tpm2_generator_selinux — Security Enhanced Linux Policy for the systemd_tpm2_generator processes 🎀

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the systemd_tpm2_generator processes via flexible mandatory access control. no cap, that's the whole vibe — MAC doing its thing so your stuff stays safe 🫶

The systemd_tpm2_generator processes execute with the systemd_tpm2_generator_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_tpm2_generator_t

like, run it, see if anybody's home 🦋

---

🚪 ENTRYPOINTS 🚪

The systemd_tpm2_generator_t SELinux type can be entered via the systemd_tpm2_generator_exec_t file type.

The default entrypoint paths for the systemd_tpm2_generator_t domain are the following:

/usr/lib/systemd/system-generators/systemd-tpm2-generator

that's the literal one door in, bestie 🚪✨

---

👑 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 systemd_tpm2_generator policy is very flexible allowing users to setup their systemd_tpm2_generator processes in as secure a method as possible. flexible and secure, we love a multitasker 💖

The following process types are defined for systemd_tpm2_generator:

• systemd_tpm2_generator_t

Note: semanage permissive -a systemd_tpm2_generator_t can be used to make the process type systemd_tpm2_generator_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's chill but it's still snitching in the logs 😭

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. systemd_tpm2_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_tpm2_generator 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

both already on out of the box, so that's a slay 🌈

---

📂 MANAGED FILES 📂

The SELinux process type systemd_tpm2_generator_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. like SELinux is not out here overriding DAC, that's not the vibe, both have to agree 🤝

• 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

• root_t

/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

like yes that's a whole lot of paths, but every single one made the cut 💀

🗂️ 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 systemd_tpm2_generator policy is very flexible allowing users to setup their systemd_tpm2_generator processes in as secure a method as possible. same energy as before, still iconic ✨

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the systemd_tpm2_generator, 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_tpm2_generator_exec_t '/srv/systemd_tpm2_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_tpm2_generator_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_tpm2_generator:

💜 systemd_tpm2_generator_exec_t

• Set files with the systemd_tpm2_generator_exec_t type, if you want to transition an executable to the systemd_tpm2_generator_t domain.

💜 systemd_tpm2_generator_unit_file_t

• Set files with the systemd_tpm2_generator_unit_file_t type, if you want to treat the files as systemd tpm2 generator unit content.

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 😭 chcon is a vibe, semanage fcontext is a commitment 💍

---

🛠️ 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. a GUI!! for the people who like clicking 🖱️💅
