SYSTEMD_SSH_GENERATOR_SELINUX(8)

💅 systemd_ssh_generator_selinux — bestie edition 💅

okay so this is the systemd_ssh_generator_selinux(8) manual page, and it's literally all about the SELinux policy for systemd_ssh_generator processes. no cap, it's giving security realness. 🛡️✨

✨ NAME ✨

systemd_ssh_generator_selinux — Security Enhanced Linux Policy for the systemd_ssh_generator processes

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the systemd_ssh_generator processes via flexible mandatory access control. it's giving "we control everything around here" energy, fr fr. 👑

The systemd_ssh_generator processes execute with the systemd_ssh_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_ssh_generator_t

🚪 ENTRYPOINTS 🚪

The systemd_ssh_generator_t SELinux type can be entered via the systemd_ssh_generator_exec_t file type.

the default entrypoint paths for the systemd_ssh_generator_t domain are the following, bestie:

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

👯 PROCESS TYPES 👯

SELinux defines process types (domains) for each process running on the system. iconic behavior tbh.

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_ssh_generator policy is very flexible allowing users to setup their systemd_ssh_generator processes in as secure a method as possible. slay. 🔒

the following process types are defined for systemd_ssh_generator:

• systemd_ssh_generator_t

Note: semanage permissive -a systemd_ssh_generator_t can be used to make the process type systemd_ssh_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 still snitches. 💀

🎚️ BOOLEANS 🎚️

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

📁 MANAGED FILES 📁

The SELinux process type systemd_ssh_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. iykyk. 🙈

• 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

🌸 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_ssh_generator policy is very flexible allowing users to setup their systemd_ssh_generator processes in as secure a method as possible.

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the systemd_ssh_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_ssh_generator_exec_t '/srv/systemd_ssh_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_ssh_generator_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise up. 🧚

the following file types are defined for systemd_ssh_generator:

• systemd_ssh_generator_exec_t
  • Set files with the systemd_ssh_generator_exec_t type, if you want to transition an executable to the systemd_ssh_generator_t domain.
• systemd_ssh_generator_unit_file_t
  • Set files with the systemd_ssh_generator_unit_file_t type, if you want to treat the files as systemd ssh 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. so like, chcon is giving temporary tattoo energy and semanage is the real permanent ink. 💅

💻 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. ooh fancy. ✨
