lwiod_selinux(8)

💖 lwiod_selinux(8) — the SELinux tea on lwiod 💖

okay so bestie, this is the manual page for lwiod_selinux from the SELinux Policy lwiod family (lwiod_selinux(8), periodt). grab a strawberry drink 🍓 and let me walk you through it.

---

✨ NAME ✨

lwiod_selinux — the Security Enhanced Linux Policy for the lwiod processes. that's the whole vibe. 💅

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the lwiod processes via flexible mandatory access control. like, it's literally out here protecting them with vibes and rules. 🫶

The lwiod processes execute with the lwiod_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 lwiod_t

no cap, that's it. that's the check. ✨

---

🦋 ENTRYPOINTS 🦋

The lwiod_t SELinux type can be entered via the lwiod_exec_t file type. that's the door, bestie, and it's iconic.

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

/usr/bin/lwiod, /opt/likewise/sbin/lwiod

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every single one gets a little domain, main character energy fr fr.

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

Policy governs the access confined processes have to files. the SELinux lwiod policy is very flexible, allowing users to setup their lwiod processes in as secure a method as possible. it's giving customizable security, and we're obsessed. 🌈

The following process types are defined for lwiod:

• lwiod_t

Note: semanage permissive -a lwiod_t can be used to make the process type lwiod_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 stuff but it still talks about it, iykyk. 😭

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. the lwiod policy is extremely flexible and has several booleans that allow you to manipulate the policy and run lwiod 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 confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

setsebool -P kerberos_enabled 1

three booleans, all enabled by default, all slaying. ⭐

---

🧚 MANAGED FILES 🧚

The SELinux process type lwiod_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. note: the process's UID still needs to have DAC permissions — SELinux isn't out here doing everything for you, bestie. 🙈

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. it's the file's whole identity, honestly. 🦋

You can see the context of a file using the -Z option to ls.

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

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the lwiod. 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. 🎀

semanage fcontext -a -t lwiod_exec_t '/srv/lwiod/content(/.*)?'
restorecon -R -v /srv/mylwiod_content

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

The following file types are defined for lwiod:

lwiod_exec_t

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

Paths:

/usr/bin/lwiod, /opt/likewise/sbin/lwiod

lwiod_var_lib_t

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

lwiod_var_run_t

• Set files with the lwiod_var_run_t type, if you want to store the lwiod files under the /run or /var/run directory.

lwiod_var_socket_t

• Set files with the lwiod_var_socket_t type, if you want to treat the files as lwiod var socket data.

Paths:

/var/lib/likewise/.lwiod, /var/lib/likewise-open/.lwiod

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 = chcon, permanent = the whole semanage fcontext + restorecon combo. don't forget the last step, i'm literally begging. 😭

---

🌈 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 whole GUI, for the visual learners. 👑

okay that's the whole page bestie, you're officially caught up 🫶 — this one's lwiod from 26-10-06, the lwiod_selinux(8) era, and yes i'm aware that date format is giving chaos but it's canon 💀✨
