rabbitmq_selinux(8)

💖 rabbitmq_selinux(8) — the SELinux policy for rabbitmq, bestie edition 💖

okay so this is rabbitmq_selinux(8), part of the SELinux Policy rabbitmq family, and it's literally your whole guide to how SELinux treats the rabbitmq processes. grab a snack, we're getting into it 🍓

---

✨ NAME ✨

rabbitmq_selinux — the Security Enhanced Linux Policy for the rabbitmq processes. that's it, that's the vibe 🫶

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the rabbitmq processes via flexible mandatory access control. yes, mandatory. SELinux does not do "optional" 💅

The rabbitmq processes execute with the rabbitmq_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier.

for example:

ps -eZ | grep rabbitmq_t

easy. iconic. no cap ✨

---

🦋 ENTRYPOINTS 🦋

The rabbitmq_t SELinux type can be entered via the rabbitmq_exec_t file type. that's the doorway, iykyk 🚪

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

/usr/lib/rabbitmq/lib/rabbitmq_server-.*/sbin/rabbitmq-server

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. every single one. it's giving organized 🌈

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

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

The following process types are defined for rabbitmq:

rabbitmq_t

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

so like, permissive = it stops blocking you but it's still gonna talk about you in the group chat (the AVC messages). 💀

---

💅 BOOLEANS 💅

SELinux policy is customizable based on least access required. rabbitmq policy is extremely flexible and has several booleans that allow you to manipulate the policy and run rabbitmq with the tightest access possible. tightest access, bestie, we love a lock-down 🔥

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

If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

setsebool -P kerberos_enabled 1

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

(btw that last one starts OFF, so if you need NIS you gotta flip it yourself. main character energy 🎀)

---

🐇 PORT TYPES 🐇

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for rabbitmq:

rabbitmq_port_t

Default Defined Ports:

          tcp 25672

one port. one iconic little port. 👑

---

🧚 MANAGED FILES 🧚

The SELinux process type rabbitmq_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. (SELinux is not doing DAC's job, they're coworkers, not the same person, ok? 😭)

⭐ FILE CONTEXTS ⭐

SELinux requires files to have an extended attribute to define the file type. it's an xattr thing, we don't make the rules (we absolutely make the rules, SELinux makes the rules) 😌

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the rabbitmq, 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 rabbitmq_exec_t '/srv/rabbitmq/content(/.*)?'
restorecon -R -v /srv/myrabbitmq_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for rabbitmq:

rabbitmq_conf_t

• Set files with the rabbitmq_conf_t type, if you want to treat the files as rabbitmq configuration data, usually stored under the /etc directory.

rabbitmq_exec_t

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

rabbitmq_initrc_exec_t

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

rabbitmq_tmp_t

• Set files with the rabbitmq_tmp_t type, if you want to store rabbitmq temporary files in the /tmp directories.

rabbitmq_tmpfs_t

• Set files with the rabbitmq_tmpfs_t type, if you want to store rabbitmq files on a tmpfs file system.

rabbitmq_unit_file_t

• Set files with the rabbitmq_unit_file_t type, if you want to treat the files as rabbitmq unit content.

rabbitmq_var_lib_t

• Set files with the rabbitmq_var_lib_t type, if you want to store the rabbitmq files under the /var/lib directory.

rabbitmq_var_lock_t

• Set files with the rabbitmq_var_lock_t type, if you want to treat the files as rabbitmq var lock data, stored under the /var/lock directory

rabbitmq_var_log_t

• Set files with the rabbitmq_var_log_t type, if you want to treat the data as rabbitmq var log data, usually stored under the /var/log directory.

rabbitmq_var_run_t

• Set files with the rabbitmq_var_run_t type, if you want to store the rabbitmq 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.

so like — chcon is the temporary tattoo, semanage fcontext + restorecon is the real ink. don't mix them up or you'll be sad in a reboot 😭

---

🌈 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 port can also be used to manipulate the port definitions

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.

(yes a GUI. for the girlies who want buttons instead of flags 🫶)
