✨ NAME ✨

ulogd_selinux is the manual page for the Security Enhanced Linux Policy for the ulogd processes, bestie πŸ’–. This is the ulogd_selinux(8) tea, and it's all about keeping those ulogd processes slayed and secure.

πŸ›‘οΈ DESCRIPTION πŸ›‘οΈ

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

The ulogd processes execute with the ulogd_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 ulogd_t

πŸšͺ ENTRYPOINTS πŸšͺ

The ulogd_t SELinux type can be entered via the ulogd_exec_t file type. Iconic behavior, honestly.

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

  • /usr/bin/ulogd

πŸ‘‘ PROCESS TYPES πŸ‘‘

SELinux defines process types (domains) for each process running on the system. Main character energy for every single process, fr fr.

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

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

The following process types are defined for ulogd:

  • ulogd_t
πŸ’‘ Note: semanage permissive -a ulogd_t can be used to make the process type ulogd_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. ulogd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ulogd with the tightest access possible. Tightest access possible is the vibe ✨.

  • daemons_dontaudit_scheduling β€” 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
  • fips_mode β€” 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
  • nscd_use_shm β€” If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1

πŸ“‚ MANAGED FILES πŸ“‚

The SELinux process type ulogd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the process's UID still needs to have DAC permissions, bestie β€” SELinux is not out here doing everything alone πŸ”₯.

  • cluster_conf_t β€” default paths:
    • /etc/cluster(/.*)?
  • cluster_var_lib_t β€” default paths:
    • /var/lib/pcsd(/.*)?
    • /var/lib/cluster(/.*)?
    • /var/lib/openais(/.*)?
    • /var/lib/pengine(/.*)?
    • /var/lib/corosync(/.*)?
    • /usr/lib/heartbeat(/.*)?
    • /var/lib/heartbeat(/.*)?
    • /var/lib/pacemaker(/.*)?
  • cluster_var_run_t β€” default paths:
    • /run/crm(/.*)?
    • /run/cman_.*
    • /run/rsctmp(/.*)?
    • /run/aisexec.*
    • /run/heartbeat(/.*)?
    • /run/pcsd-ruby.socket
    • /run/corosync-qnetd(/.*)?
    • /run/corosync-qdevice(/.*)?
    • /run/pcsd.socket
    • /run/corosync.pid
    • /run/cpglockd.pid
    • /run/rgmanager.pid
    • /run/cluster/rgmanager.sk
  • root_t β€” default paths:
    • /sysroot/.aleph-version.json
    • /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
    • /
    • /initrd
    • /var/lib/ntp

🏷️ 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 ulogd policy is very flexible, allowing users to setup their ulogd processes in as secure a method as possible. Secure and flexible? We love a multitalented icon πŸ’….

πŸŽ€ STANDARD FILE CONTEXT πŸŽ€

SELinux defines the file context types for ulogd. 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 ulogd_exec_t '/srv/ulogd/content(/.*)?'
restorecon -R -v /srv/myulogd_content
πŸ’‘ Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for ulogd:

  • ulogd_etc_t β€” Set files with the ulogd_etc_t type, if you want to store ulogd files in the /etc directories.
  • ulogd_exec_t β€” Set files with the ulogd_exec_t type, if you want to transition an executable to the ulogd_t domain.
  • ulogd_initrc_exec_t β€” Set files with the ulogd_initrc_exec_t type, if you want to transition an executable to the ulogd_initrc_t domain.
  • ulogd_modules_t β€” Set files with the ulogd_modules_t type, if you want to treat the files as ulogd modules.
  • ulogd_var_log_t β€” Set files with the ulogd_var_log_t type, if you want to treat the data as ulogd var log data, usually stored under the /var/log directory.
πŸ’‘ 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.

πŸ› οΈ COMMANDS πŸ› οΈ

  • 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.
