okay bestie, welcome to tgtd_selinux(8) — the SELinux policy page for the tgtd processes, but make it make sense 💅✨

🌸 NAME 🌸

tgtd_selinux — Security Enhanced Linux Policy for the tgtd processes 🎀

💖 DESCRIPTION 💖

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

The tgtd processes execute with the tgtd_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 tgtd_t

✨ ENTRYPOINTS ✨

The tgtd_t SELinux type can be entered via the tgtd_exec_t file type. slay 💅

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

/usr/bin/tgtd

🦋 PROCESS TYPES 🦋

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

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

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

The following process types are defined for tgtd:

  • tgtd_t
Note: semanage permissive -a tgtd_t can be used to make the process type tgtd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. bestie, read that twice if you need to 👀

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. tgtd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run tgtd with the tightest access possible. lowkey obsessed with least privilege 🎀

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 tgtd_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 matters, don't forget her 💖

  • cluster_var_lib_t

  • tgtd_var_run_t
/run/tgtd.*

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. it's giving labeled-and-loaded 💅

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

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for the tgtd, 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. bestie, that's the whole relabel pipeline ✨

semanage fcontext -a -t tgtd_exec_t '/srv/tgtd/content(/.*)?'
restorecon -R -v /srv/mytgtd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 😭💖

The following file types are defined for tgtd:

  • tgtd_exec_t
    • Set files with the tgtd_exec_t type, if you want to transition an executable to the tgtd_t domain.
  • tgtd_initrc_exec_t
    • Set files with the tgtd_initrc_exec_t type, if you want to transition an executable to the tgtd_initrc_t domain.
  • tgtd_tmp_t
    • Set files with the tgtd_tmp_t type, if you want to store tgtd temporary files in the /tmp directories.
  • tgtd_tmpfs_t
    • Set files with the tgtd_tmpfs_t type, if you want to store tgtd files on a tmpfs file system.
  • tgtd_var_lib_t
    • Set files with the tgtd_var_lib_t type, if you want to store the tgtd files under the /var/lib directory.
  • tgtd_var_run_t
    • Set files with the tgtd_var_run_t type, if you want to store the tgtd 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. permanent means permanent, 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.
