minissdpd_selinux(8)

💖 minissdpd_selinux — the manual page, but make it make sense 💖

okay so bestie, this is minissdpd_selinux(8) and it's literally the SELinux policy page for the minissdpd processes. yes, that minissdpd. buckle up 🎀

---

✨ NAME ✨

minissdpd_selinux — the Security Enhanced Linux Policy for the minissdpd processes 🦋

---

🌸 DESCRIPTION 🌸

so, Security-Enhanced Linux secures the minissdpd processes via flexible mandatory access control. that's the whole vibe — flexible, mandatory, access control. slay.

The minissdpd processes literally execute with the minissdpd_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier. easy.

for example:

ps -eZ | grep minissdpd_t

no cap, that's it. 💅

---

🧚 ENTRYPOINTS 🧚

the minissdpd_t SELinux type can be entered via the minissdpd_exec_t file type. that's the doorway, okay.

the default entrypoint paths for the minissdpd_t domain are literally:

/usr/bin/minissdpd

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. every single one. iconic behavior honestly.

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 minissdpd policy is very flexible, allowing users to setup their minissdpd processes in as secure a method as possible. tightest access possible? yes please 🫶

the following process types are defined for minissdpd:

minissdpd_t

Note: semanage permissive -a minissdpd_t can be used to make the process type minissdpd_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 things but it's still watching you, lowkey. 👀

---

⭐ BOOLEANS ⭐

SELinux policy is customizable based on least access required. the minissdpd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run minissdpd with the tightest access possible. obsessed with the flexibility honestly.

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. it's 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. also enabled by default.

setsebool -P fips_mode 1

If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. this one is disabled by default, so you gotta do it yourself.

setsebool -P secure_mode_insmod 1

---

🦋 MANAGED FILES 🦋

the SELinux process type minissdpd_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and bestie, note that the processes UID still need to have DAC permissions. SELinux isn't out here handing out free passes, periodt.

cluster_conf_t

/etc/cluster(/.*)?

cluster_var_lib_t

/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. that's just how it is, no skipping.

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 minissdpd policy is very flexible, allowing users to setup their minissdpd processes in as secure a method as possible. (yes, it says that twice. it's that good. 💅)

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the minissdpd, and 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, actually put them there.

semanage fcontext -a -t minissdpd_exec_t '/srv/minissdpd/content(/.*)?'
restorecon -R -v /srv/myminissdpd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex my beloved 😭

the following file types are defined for minissdpd:

minissdpd_conf_t

• Set files with the minissdpd_conf_t type, if you want to treat the files as minissdpd configuration data, usually stored under the /etc directory.

minissdpd_exec_t

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

minissdpd_initrc_exec_t

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

minissdpd_var_run_t

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

Paths:

/run/minissdpd.pid, /run/minissdpd.sock

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. chcon is giving quick-fix energy, semanage fcontext is giving main character commitment. 🔥

---

🔥 COMMANDS 🔥

semanage fcontext can also be used to manipulate default file context mappings. (it's in the name, bestie)

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. all four at once, versatile icon.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings. for the girlies who prefer clicking to typing 🫶

and that's the whole page, bestie! this one was written by the minissdpd crew, dated 26-10-06, and it's the minissdpd_selinux(8) page from the SELinux Policy minissdpd manual. go forth and label things correctly 🌸💅✨
