okay bestie, welcome to deltacloudd_selinux(8) 💅 — the SELinux manual page for deltacloudd processes. It's giving mandatory access control, tight policy vibes, and absolutely zero chill about labels. 🦋✨

💖 NAME 💖

deltacloudd_selinux — Security Enhanced Linux Policy for the deltacloudd processes. 🎀

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the deltacloudd processes via flexible mandatory access control. no cap. 🔥

The deltacloudd processes execute with the deltacloudd_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 deltacloudd_t

🦋 ENTRYPOINTS 🦋

The deltacloudd_t SELinux type can be entered via the deltacloudd_exec_t file type. 🫶

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

/usr/bin/deltacloudd

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

The following process types are defined for deltacloudd:

  • deltacloudd_t
Note: semanage permissive -a deltacloudd_t can be used to make the process type deltacloudd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. 😭

✨ BOOLEANS ✨

SELinux policy is customizable based on least access required. deltacloudd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run deltacloudd with the tightest access possible. 💅

  • 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. Command: 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. Command: 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. Command: setsebool -P nis_enabled 1

🎀 MANAGED FILES 🎀

The SELinux process type deltacloudd_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. 🙈

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

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for deltacloudd; if you wanted to store files with these types in 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 deltacloudd_exec_t
'/srv/deltacloudd/content(/.*)?'
restorecon -R -v /srv/mydeltacloudd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. ✨

The following file types are defined for deltacloudd:

  • deltacloudd_exec_t — set files with the deltacloudd_exec_t type if you want to transition an executable to the deltacloudd_t domain.
  • deltacloudd_log_t — set files with the deltacloudd_log_t type if you want to treat the data as deltacloudd log data, usually stored under the /var/log directory.
  • deltacloudd_tmp_t — set files with the deltacloudd_tmp_t type if you want to store deltacloudd temporary files in the /tmp directories.
  • deltacloudd_var_run_t — set files with the deltacloudd_var_run_t type if you want to store the deltacloudd 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. 💅

💅 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.
