💅 pingd_selinux(8) — the SELinux tea for pingd 🫶

okay so bestie, this is the pingd_selinux manual page — it's the Security Enhanced Linux policy situation for the pingd processes, and honestly it's giving ✨ mandatory access control ✨ but make it cute. Let's get into it.

---

🌸 NAME 🌸

pingd_selinux — Security Enhanced Linux Policy for the pingd processes. that's it, that's the vibe 💅

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the pingd processes via flexible mandatory access control. like, it's not just vibes keeping things safe, it's actual enforced policy, no cap 🔥

The pingd processes execute with the pingd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example, run this and see what's up:

ps -eZ | grep pingd_t

---

🚪 ENTRYPOINTS 🚪

So the pingd_t SELinux type can be entered via the pingd_exec_t file type. that's the doorway, the main character entrance if you will 👑

The default entrypoint paths for the pingd_t domain are literally just:

/usr/bin/pingd

---

🎀 PROCESS TYPES 🎀

SELinux defines process types (domains) for each process running on the system. yep, every process gets its own little domain moment 💖

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

Policy governs the access confined processes have to files. SELinux pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible. lowkey obsessed with how customizable this is 🦋

The following process types are defined for pingd:

ping_t, pingd_t

💀 Note: semanage permissive -a pingd_t can be used to make the process type pingd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it stops blocking but it's still watching you, iykyk 🙈

---

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. pingd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pingd with the tightest access possible. tightest access = the lewk we're going for 💅

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 system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

---

🔌 PORT TYPES 🔌

SELinux defines port types to represent TCP and UDP ports. ports are literally the doorways of networking, slay 🚪✨

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 pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible. same energy as before, just ports this time 🫶

The following port types are defined for pingd:

pingd_port_t

Default Defined Ports:

          tcp 9125

so it's tcp 9125, remember that number bestie 🔥

---

📂 MANAGED FILES 📂

The SELinux process type pingd_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, SELinux isn't doing everything for you, DAC still matters, don't @ me 😭)

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(/.*)?

/initrd
/var/lib/ntp

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. it's giving "labels on everything" and honestly iconic 🏷️✨

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 pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible. say it with me: very flexible 💖

---

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the pingd, 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. two steps, no skipping, bestie 🫶

semanage fcontext -a -t pingd_exec_t '/srv/pingd/content(/.*)?'
restorecon -R -v /srv/mypingd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🌸

The following file types are defined for pingd:

pingd_etc_t

• Set files with the pingd_etc_t type, if you want to store pingd files in the /etc directories.

pingd_exec_t

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

pingd_initrc_exec_t

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

pingd_modules_t

• Set files with the pingd_modules_t type, if you want to treat the files as pingd modules.

💀 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 vs permanent is a whole different vibe, don't forget it fr fr

---

🛠️ COMMANDS 🛠️

semanage fcontext can also be used to manipulate default file context mappings. slay 💅

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. GUI girlies, this one's for you 🎀
