💅 mon_procd_selinux(8) — SELinux Policy for mon_procd 💅

Okay bestie, buckle up: this is the SELinux policy page for the mon_procd processes, and it’s giving secure-but-flexible main character energy. 🎀

🌸 NAME 🌸

mon_procd_selinux — Security Enhanced Linux Policy for the mon_procd processes.

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the mon_procd processes via flexible mandatory access control. No cap, that’s the whole vibe. 💖

The mon_procd processes execute with the mon_procd_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 mon_procd_t

🦋 ENTRYPOINTS 🦋

The mon_procd_t SELinux type can be entered via the mon_procd_exec_t file type. Iconic little doorway, honestly. 🚪✨

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

/usr/bin/mon_procd

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. Periodt. 💅

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

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

The following process types are defined for mon_procd:

  • mon_procd_t
Note: semanage permissive -a mon_procd_t can be used to make the process type mon_procd_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. mon_procd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mon_procd with the tightest access possible. Tightest access = bestie behavior, fr fr. 🔥

  • daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this 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 this boolean. Enabled by default.
setsebool -P fips_mode 1

🌈 MANAGED FILES 🌈

The SELinux process type mon_procd_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. Don’t forget that part, bestie. 😭

  • cluster_conf_t
    • /etc/cluster(/.*)?
  • cluster_var_lib_t
    • /var/lib/pcsd(/.*)?

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

🍓 STANDARD FILE CONTEXT 🍓

SELinux defines the file context types for the mon_procd. 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 mon_procd_exec_t '/srv/mon_procd/content(/.*)?'
restorecon -R -v /srv/mymon_procd_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 mon_procd:

  • mon_procd_exec_t — set files with the mon_procd_exec_t type if you want to transition an executable to the mon_procd_t domain.
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.
