vnstatd_selinux(8)

✨ vnstatd_selinux(8) ✨

okay so bestie, you're looking at the vnstatd_selinux page from the SELinux Policy vnstatd manual, and honestly it's giving "niche but iconic" 💅. Let's get into it.

🎀 NAME 🎀

vnstatd_selinux — the Security Enhanced Linux Policy for the vnstatd processes, and yes she's the main character of this page 🫶

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the vnstatd processes via flexible mandatory access control. Literally the whole point ✨

The vnstatd processes execute with the vnstatd_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 vnstatd_t

like, that's the vibe check for your processes, no cap 🔍

🦋 ENTRYPOINTS 🦋

The vnstatd_t SELinux type can be entered via the vnstatd_exec_t file type.

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

/usr/bin/vnstatd

that's the door, and there's only one 🚪✨

💜 PROCESS TYPES 💜

SELinux defines process types (domains) for each process running on the system — yes, every process gets its own little domain era 🎀

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

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

The following process types are defined for vnstatd:

• vnstat_t
• vnstatd_t

Note: semanage permissive -a vnstatd_t can be used to make the process type vnstatd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she's not blocking you but she IS still writing it down in the group chat 💀

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. vnstatd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run vnstatd with the tightest access possible. lowkey the most fun part of the whole page ngl 🎀

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

both of these are already on out of the box, so like, slay, no action needed 💅

🌟 MANAGED FILES 🌟

The SELinux process type vnstatd_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 doing DAC's job, fr fr 🙈)

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

/run/crm(/.*)?
/run/cman_.*
/run/rsctmp(/.*)?
/run/aisexec.*
/run/heartbeat(/.*)?
/run/pcsd-ruby.socket
/run/corosync-qnetd(/.*)?
/run/corosync-qdevice(/.*)?
/run/pcsd.socket
/run/corosync.pid
/run/cpglockd.pid
/run/rgmanager.pid
/run/cluster/rgmanager.sk

root_t

/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

vnstatd_var_lib_t

/var/lib/vnstat(/.*)?

vnstatd_var_run_t

/run/vnstat.*

that's the full roster, every single one of them, no skipping 🫶

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. literally the file's whole identity ✨

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the vnstatd, 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 vnstatd_exec_t '/srv/vnstatd/content(/.*)?'
restorecon -R -v /srv/myvnstatd_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 vnstatd:

vnstatd_exec_t

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

vnstatd_initrc_exec_t

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

vnstatd_var_lib_t

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

vnstatd_var_run_t

• Set files with the vnstatd_var_run_t type, if you want to store the vnstatd 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 and semanage fcontext + restorecon is the real one 😭

🍓 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. a GUI!! for the girlies who like clicking 👑💻
