💅 telepathy_msn_selinux(8) — the SELinux policy for telepathy_msn, bestie edition 🦋

okay so this is the telepathy_msn_selinux page from the SELinux Policy telepathy_msn manual, and we're gonna get into it 💖

✨ NAME ✨

telepathy_msn_selinux — Security Enhanced Linux Policy for the telepathy_msn processes 🎀

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the telepathy_msn processes via flexible mandatory access control. no cap, that's the whole vibe of SELinux — it's giving "I decide what you're allowed to touch" 👑

The telepathy_msn processes execute with the telepathy_msn_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 telepathy_msn_t

literally just run that and see who's out here wearing the telepathy_msn_t label 🕵️‍♀️

🚪 ENTRYPOINTS 🚪

The telepathy_msn_t SELinux type can be entered via the telepathy_msn_exec_t file type.

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

/usr/libexec/telepathy-haze, /usr/libexec/telepathy-butterfly

those two are the doors into the domain, iykyk 🚪✨

🧬 PROCESS TYPES 🧬

SELinux defines process types (domains) for each process running on the system

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

Policy governs the access confined processes have to files. SELinux telepathy_msn policy is very flexible allowing users to setup their telepathy_msn processes in as secure a method as possible.

The following process types are defined for telepathy_msn:

telepathy_msn_t

Note: semanage permissive -a telepathy_msn_t can be used to make the process type telepathy_msn_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 tells on you — snitch behaviour fr

🎛️ BOOLEANS 🎛️

SELinux policy is customizable based on least access required. telepathy_msn policy is extremely flexible and has several booleans that allow you to manipulate the policy and run telepathy_msn with the tightest access possible. tightest access = main character energy 🔥

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

If you want to allow the Telepathy connection managers to connect to any network port, you must turn on the telepathy_connect_all_ports boolean. Disabled by default.

setsebool -P telepathy_connect_all_ports 1

If you want to allow the Telepathy connection managers to connect to any generic TCP port, you must turn on the telepathy_tcp_connect_generic_network_ports boolean. Disabled by default.

setsebool -P telepathy_tcp_connect_generic_network_ports 1

the -P is important bestie, it makes it persist across reboots — without it your boolean just evaporates 😭

📂 MANAGED FILES 📂

The SELinux process type telepathy_msn_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. (yes, SELinux is a second bouncer, you still gotta get past the UID one first 🙈)

cache_home_t

/root/.cache(/.*)?
/home/[^/]+/.nv(/.*)?
/home/[^/]+/.cache(/.*)?

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

telepathy_msn_tmp_t

(no default paths listed for this one, she's mysterious like that 💅)

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type.

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the telepathy_msn, 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.

semanage fcontext -a -t telepathy_msn_exec_t '/srv/telepathy_msn/content(/.*)?'
restorecon -R -v /srv/mytelepathy_msn_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex jumpscare, but she's harmless 🧚

The following file types are defined for telepathy_msn:

telepathy_msn_exec_t

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

Paths:

/usr/libexec/telepathy-haze, /usr/libexec/telepathy-butterfly

telepathy_msn_tmp_t

• Set files with the telepathy_msn_tmp_t type, if you want to store telepathy msn temporary files in the /tmp directories.

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 vs permanent is literally the whole plot here — chcon is a fling, semanage fcontext + restorecon is the committed relationship 💖

🛠️ 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 when the terminal is doing too much 🎀)
