locate_selinux(8)

✨ locate_selinux(8) — the glow-up edition ✨

okay so bestie, buckle up 🎀 this is the SELinux policy page for the locate processes, and it's literally the whole manual name situation: locate_selinux. we're talking about how SELinux keeps locate in check, and honestly? it's giving secure. 💅

🦋 NAME

locate_selinux — the Security Enhanced Linux policy for the locate processes. yes, that's the whole vibe. no cap.

---

🌸 DESCRIPTION

Security-Enhanced Linux secures the locate processes via flexible mandatory access control. periodt. ✨

The locate processes execute with the locate_t SELinux type. You can check if you've got these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep locate_t

like, go run that, bestie, see what's up 👑

---

🧚 ENTRYPOINTS

The locate_t SELinux type can be entered via the locate_exec_t file type. 🚪✨

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

/etc/cron.daily/[sm]locate, /usr/bin/updatedb.*

iconic paths, honestly. 🫶

---

👑 PROCESS TYPES

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

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

Policy governs the access confined processes have to files. SELinux locate policy is very flexible, allowing users to setup their locate processes in as secure a method as possible. highkey obsessed with how customizable this is. 🔥

The following process types are defined for locate:

• locate_t

Note: semanage permissive -a locate_t can be used to make the process type locate_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, you're not blocking anything, but the receipts are still being kept. 😭💀

---

🌈 BOOLEANS

SELinux policy is customizable based on least access required. locate policy is extremely flexible and has several booleans that allow you to manipulate the policy and run locate with the tightest access possible. we love a configurable queen. 👑

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

---

🍓 MANAGED FILES

The SELinux process type locate_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 out here replacing your normal perms, bestie, it's layered on top 🧚)

krb5_host_rcache_t

/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

locate_var_lib_t

/var/lib/[sm]locate(/.*)?
/var/lib/plocate(/.*)?

locate_var_run_t

/run/mlocate.daily.lock

---

💜 FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type. yes, every file gets its little label, it's like a name tag but for security. 🏷️✨

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

🎀 STANDARD FILE CONTEXT

SELinux defines the file context types for the locate, 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 relabeling but make it official. 💅

semanage fcontext -a -t locate_exec_t '/srv/locate/content(/.*)?'
restorecon -R -v /srv/mylocate_content

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

The following file types are defined for locate:

• locate_exec_t — Set files with the locate_exec_t type, if you want to transition an executable to the locate_t domain.

Paths:

/etc/cron.daily/[sm]locate, /usr/bin/updatedb.*

• locate_var_lib_t — Set files with the locate_var_lib_t type, if you want to store the locate files under the /var/lib directory.

Paths:

/var/lib/[sm]locate(/.*)?, /var/lib/plocate(/.*)?

• locate_var_run_t — Set files with the locate_var_run_t type, if you want to store the locate 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, chcon is the quick fix, semanage fcontext + restorecon is the forever commitment. 💍

---

⭐ 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. (for the visual learners 💖)
