rrdcached_selinux(8)

rrdcached_selinux(8) bestie!! 💖 This is the SELinux Policy page for rrdcached, and we are gonna read it like a group chat — but every detail stays, no cap. The manual name is literally rrdcached_selinux(8), and the policy vibe is SELinux Policy rrdcached. Let’s gooo. ✨

✨ NAME ✨

rrdcached_selinux — Security Enhanced Linux Policy for the rrdcached processes. That’s the whole name section, periodt. 💅

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the rrdcached processes via flexible mandatory access control. iconic behavior honestly.

The rrdcached processes execute with the rrdcached_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. Like this:

ps -eZ | grep rrdcached_t

slay, now you can see what’s up. 🦋

🚪 ENTRYPOINTS 🚪

The rrdcached_t SELinux type can be entered via the rrdcached_exec_t file type. entrypoint energy.

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

/usr/bin/rrdcached

one path, one icon, one vibe. 🌈

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. domains are literally the main characters here.

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

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

The following process types are defined for rrdcached:

• rrdcached_t

Note: semanage permissive -a rrdcached_t can be used to make the process type rrdcached_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, permissive ≠ invisible, bestie — the receipts still exist. 👀

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. rrdcached policy is extremely flexible and has several booleans that allow you to manipulate the policy and run rrdcached with the tightest access possible. boolean customization is giving controlled chaos. 🎀

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.

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.

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.

setsebool -P nis_enabled 1

three booleans, three little switches, no cap. 🦋

📁 MANAGED FILES 📁

The SELinux process type rrdcached_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 out here replacing DAC, bestie — they’re coworkers. 💅

rrdcached_tmp_t — no default paths are listed for this one on the page. it’s mysterious, it’s lowkey, it’s valid. 🙈

rrdcached_var_run_t

/run/rrdcached.*

managed file types: collected, labeled, and slaying. 🌈

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. yes, files have lore too. 💖

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the rrdcached. 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. Like so:

semanage fcontext -a -t rrdcached_exec_t '/srv/rrdcached/content(/.*)?'
restorecon -R -v /srv/myrrdcached_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies stay winning. ✨

The following file types are defined for rrdcached:

• rrdcached_exec_t — Set files with the rrdcached_exec_t type, if you want to transition an executable to the rrdcached_t domain.
• rrdcached_tmp_t — Set files with the rrdcached_tmp_t type, if you want to store rrdcached temporary files in the /tmp directories.
• rrdcached_var_run_t — Set files with the rrdcached_var_run_t type, if you want to store the rrdcached 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. temporary labels are giving temporary, bestie — make it permanent with the right tools. 💅

🛠️ COMMANDS 🛠️

semanage fcontext can also be used to manipulate default file context mappings. mapping magic.

semanage permissive can also be used to manipulate whether or not a process type is permissive. permissive permissions, but make it semanage.

semanage module can also be used to enable/disable/install/remove policy modules. module mood swings handled.

semanage boolean can also be used to manipulate the booleans. boolean business, sorted.

system-config-selinux is a GUI tool available to customize SELinux policy settings. GUI girlies, this one’s for you.
