💖 abrt_helper_selinux(8): the abrt_helper SELinux bestie guide 💖

🌸 NAME 🌸

abrt_helper_selinux — the Security Enhanced Linux Policy for the abrt_helper processes. Yes bestie, we're getting into SELinux policy for these specific helper processes. 💅

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the abrt_helper processes via flexible mandatory access control. It’s giving locked-down-but-flexible, no cap.

The abrt_helper processes execute with the abrt_helper_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 abrt_helper_t

🚪 ENTRYPOINTS 🚪

The abrt_helper_t SELinux type can be entered via the abrt_helper_exec_t file type.

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

/usr/bin/abrt-pyhook-helper

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. 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. SELinux abrt_helper policy is very flexible, allowing users to set up their abrt_helper processes in as secure a method as possible.

The following process types are defined for abrt_helper:

  • abrt_helper_t
Note: semanage permissive -a abrt_helper_t can be used to make the process type abrt_helper_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So it’s permissive, not invisible — the receipts still show up. 😭

🎚️ BOOLEANS 🎚️

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

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 abrt_helper_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.

  • abrt_var_cache_t
    • /var/tmp/abrt(/.*)?
    • /var/cache/abrt(/.*)?
    • /var/spool/abrt(/.*)?
    • /var/spool/debug(/.*)?
    • /var/cache/abrt-di(/.*)?
    • /var/spool/rhsm/debug(/.*)?
  • 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 abrt_helper policy is very flexible, allowing users to set up their abrt_helper processes in as secure a method as possible.

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the abrt_helper. 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 abrt_helper_exec_t
'/srv/abrt_helper/content(/.*)?'
restorecon -R -v /srv/myabrt_helper_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning. ✨

The following file types are defined for abrt_helper:

  • abrt_helper_exec_t — Set files with the abrt_helper_exec_t type, if you want to transition an executable to the abrt_helper_t domain.
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 glow-up vs permanent labeling era — choose wisely. 💅

🛠️ 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.
