💖 mip6d_selinux(8) — the SELinux tea on mip6d 💖

okay bestie, gather round, because today we're learning about mip6d_selinux — the Security Enhanced Linux Policy for the mip6d processes. yes it's a whole manual page, and yes we're gonna make it cute. 🎀

✨ NAME ✨

mip6d_selinux — Security Enhanced Linux Policy for the mip6d processes. that's it, that's the whole vibe. 🌸

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the mip6d processes via flexible mandatory access control. like, it's giving boundaries but make it security. 💅

the mip6d processes execute with the mip6d_t SELinux type. and you can literally check if you have these processes running by executing the ps command with the -Z qualifier. the -Z is the main character here, fr fr. 👑

for example:

ps -eZ | grep mip6d_t

ngl, that's the whole check. slay. ⭐

🚪 ENTRYPOINTS 🚪

the mip6d_t SELinux type can be entered via the mip6d_exec_t file type. that's the doorway, iykyk. 🚪✨

the default entrypoint paths for the mip6d_t domain are the following:

/usr/sbin/mip6d

one path. one. iconic minimalism. 💜

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every process gets its own little domain. we love organized. 🌈

you can see the context of a process using the -Z option to ps. same -Z as before, she's consistent. 🩷

Policy governs the access confined processes have to files. SELinux mip6d policy is very flexible allowing users to setup their mip6d processes in as secure a method as possible. flexible and secure, we love a dual threat. 💅

the following process types are defined for mip6d:

  • mip6d_t
Note: semanage permissive -a mip6d_t can be used to make the process type mip6d_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's chill about denying, but it's still gonna tell on you. 😭 the receipts stay.

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. mip6d policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mip6d with the tightest access possible. tightest access possible = the vibe check of security settings. 🔥

  • 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

two booleans, both already on by default. we love a low-maintenance queen. 👑

📂 MANAGED FILES 📂

the SELinux process type mip6d_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. like, SELinux isn't doing everything for you, bestie, the UID still has a job. 🫶

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

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

root_t

/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd

ok that's a lot of paths but we read them all, because we don't skip parts in this house. 💀✨

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. it's like a little name tag for your files. 🎀

you can see the context of a file using the -Z option to ls. (yes, third -Z sighting. she's everywhere. 🙈)

Policy governs the access confined processes have to these files. SELinux mip6d policy is very flexible allowing users to setup their mip6d processes in as secure a method as possible. yes i said it twice, because the manpage says it twice, and we keep every detail around here. 💅

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the mip6d, 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 relabeling but make it a two-step glow-up. ✨

semanage fcontext -a -t mip6d_unit_file_t '/srv/mymip6d_content(/.*)?'
restorecon -R -v /srv/mymip6d_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise. 🌸

the following file types are defined for mip6d:

  • mip6d_exec_t — Set files with the mip6d_exec_t type, if you want to transition an executable to the mip6d_t domain. 🚪
  • mip6d_unit_file_t — Set files with the mip6d_unit_file_t type, if you want to treat the files as mip6d unit content. 🎀
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 chcon is the temporary tattoo and semanage fcontext + restorecon is the real ink. periodt. 💅

🛠️ 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 buttons!)
