telepath...t_selinux(8)

💖 NAME

Okay bestie, welcome to telepathy_salut_selinux(8) — yep, the telepath...t_selinux(8) girly — all about SELinux Policy telepathy_salut and its processes. This is the whole vibe: what the policy is, how it runs, booleans, files, contexts, commands, and the receipts.

✨ DESCRIPTION

Security-Enhanced Linux secures the telepathy_salut processes via flexible mandatory access control. No cap.

The telepathy_salut processes execute with the telepathy_salut_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_salut_t

🚪 ENTRYPOINTS

The telepathy_salut_t SELinux type can be entered via the telepathy_salut_exec_t file type.

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

/usr/libexec/telepathy-salut

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

The following process types are defined for telepathy_salut:

• telepathy_salut_t

Note: semanage permissive -a telepathy_salut_t can be used to make the process type telepathy_salut_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

🌈 BOOLEANS

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

• fips_mode — 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

• nis_enabled — 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

• telepathy_connect_all_ports — 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

• telepathy_tcp_connect_generic_network_ports — 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

🗂️ MANAGED FILES

The SELinux process type telepathy_salut_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.

🍓 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

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

🎀 STANDARD FILE CONTEXT

SELinux defines the file context types for the telepathy_salut; 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_salut_exec_t
'/srv/telepathy_salut/content(/.*)?'
restorecon -R -v /srv/mytelepathy_salut_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for telepathy_salut:

💅 telepathy_salut_exec_t

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

💅 telepathy_salut_tmp_t

• Set files with the telepathy_salut_tmp_t type, if you want to store telepathy salut 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.

🛠️ 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.
