πŸ’… minidlna_selinux β€” the SELinux policy for minidlna, explained by your favorite nerd bestie

okay so this is minidlna_selinux(8), and it's literally the whole ✨vibe✨ of how SELinux babysits your minidlna processes. Think of it as the group chat rules for your media server β€” who's allowed in, what they can touch, and what happens when they get too nosy. No cap, it's useful.


πŸ›‘οΈ NAME

minidlna_selinux β€” the Security Enhanced Linux Policy for the minidlna processes. That's it, that's the whole name, and honestly? iconic. πŸ‘‘


🌸 DESCRIPTION

Security-Enhanced Linux secures the minidlna processes via flexible mandatory access control. So like, flexible but mandatory, which sounds like a contradiction but bestie it's not β€” it means the policy is super configurable while still being, y'know, enforced. 😌

The minidlna processes execute with the minidlna_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 minidlna_t

Slay, now you know what's running. 🧚


πŸšͺ ENTRYPOINTS

The minidlna_t SELinux type can be entered via the minidlna_exec_t file type. So that's the doorway, fr fr.

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

/usr/bin/minidlna

One path. One icon. πŸŽ€


πŸ‘― PROCESS TYPES

SELinux defines process types (domains) for each process running on the system. Every process gets a little label, it's giving ✨organized✨.

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

Policy governs the access confined processes have to files. SELinux minidlna policy is very flexible, allowing users to set up their minidlna processes in as secure a method as possible. Flexible and secure β€” we love a multifunctional queen. πŸ’œ

The following process types are defined for minidlna:

minidlna_t
Note: semanage permissive -a minidlna_t can be used to make the process type minidlna_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So it's like, permission-wise it's chill, but the receipts are still being kept, iykyk. πŸ”₯

πŸ”˜ BOOLEANS

SELinux policy is customizable based on least access required. The minidlna policy is extremely flexible and has several booleans that allow you to manipulate the policy and run minidlna with the tightest access possible. Toggle responsibly, bestie. 🫢

If you want to determine whether minidlna can read generic user content, you must turn on the minidlna_read_generic_user_content boolean. Disabled by default.

setsebool -P minidlna_read_generic_user_content 1

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

πŸ“ MANAGED FILES

The SELinux process type minidlna_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. And real talk β€” the processes' UID still need to have DAC permissions. SELinux isn't about to override good old-fashioned Unix permissions, no ma'am. πŸ’…

πŸ—‚οΈ FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type. Every file needs its lil name tag, periodt. 🏷️

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 minidlna policy is very flexible, allowing users to set up their minidlna processes in as secure a method as possible.

πŸ” EQUIVALENCE DIRECTORIES

minidlna policy stores data with multiple different file context types under the /var/log/minidlna directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command:

semanage fcontext -a -e /var/log/minidlna /srv/minidlna
restorecon -R -v /srv/minidlna

Mapping made, labels applied, main character energy. ⭐

πŸ“Œ STANDARD FILE CONTEXT

SELinux defines the file context types for minidlna. 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 minidlna_exec_t '/srv/minidlna/content(/.*)?'
restorecon -R -v /srv/myminidlna_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. Yes, regexes. In labels. We contain multitudes. 😭

The following file types are defined for minidlna:

  • minidlna_conf_t β€” Set files with the minidlna_conf_t type if you want to treat the files as minidlna configuration data, usually stored under the /etc directory.
  • minidlna_db_t β€” Set files with the minidlna_db_t type if you want to treat the files as minidlna database content.

Paths:

/var/lib/minidlna(/.*)?, /var/cache/minidlna(/.*)?
  • minidlna_exec_t β€” Set files with the minidlna_exec_t type if you want to transition an executable to the minidlna_t domain.
  • minidlna_initrc_exec_t β€” Set files with the minidlna_initrc_exec_t type if you want to transition an executable to the minidlna_initrc_t domain.
  • minidlna_log_t β€” Set files with the minidlna_log_t type if you want to treat the data as minidlna log data, usually stored under the /var/log directory.

Paths:

/var/log/minidlna(/.*)?, /var/log/minidlna.log.*
  • minidlna_var_run_t β€” Set files with the minidlna_var_run_t type if you want to store the minidlna files under the /run or /var/run directory.
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 like β€” chcon is the temporary tattoo, semanage fcontext + restorecon is the real ink. Choose wisely bestie. πŸ™ˆ

⌨️ COMMANDS

semanage fcontext can also be used to manipulate default file context mappings. πŸ—‚οΈ

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. πŸ“¦

semanage boolean can also be used to manipulate the booleans. πŸ”˜

system-config-selinux is a GUI tool available to customize SELinux policy settings. A whole GUI! For the girlies who prefer clicking to typing, we respect it. πŸ–±οΈβœ¨
