eventlogd_selinux 💅 — the SELinux Policy eventlogd page, bestie edition

okay so this is eventlogd_selinux(8), the manual page for the SELinux policy that wrangles the eventlogd processes. it's from the SELinux Policy eventlogd collection and honestly? it's kind of iconic. let's get into it ✨

✨ NAME ✨

eventlogd_selinux — Security Enhanced Linux Policy for the eventlogd processes. that's the whole vibe. she's a policy page and she knows it 🎀

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the eventlogd processes via flexible mandatory access control. no cap, that's the actual job.

the eventlogd processes execute with the eventlogd_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 eventlogd_t

literally just run that and see what's up 🔍

🌸 ENTRYPOINTS 🌸

the eventlogd_t SELinux type can be entered via the eventlogd_exec_t file type. that's the doorway, periodt.

the default entrypoint paths for the eventlogd_t domain are the following:

/usr/bin/eventlogd, /opt/likewise/sbin/eventlogd

those two paths, exactly, no more no less 🫶

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every single one gets a little label. organized queen behavior.

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

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

the following process types are defined for eventlogd:

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

so like, permissive means she won't block you, but she's still gonna write it down in her notes 💀 the receipts stay.

🔥 BOOLEANS 🔥

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

  • 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
  • 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

both of those are enabled by default btw, so if you're checking, they should already be slaying 💅

🧚 MANAGED FILES 🧚

the SELinux process type eventlogd_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. (SELinux said "i got the labels" but DAC said "i still need my perms" — they're a team 🤝)

  • cluster_conf_t
/etc/cluster(/.*)?
  • cluster_var_lib_t
/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
/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
  • eventlogd_var_lib_t
/var/lib/likewise/db/lwi_events.db
/var/lib/likewise-open/db/lwi_events.db
  • eventlogd_var_run_t
/run/eventlogd.pid
  • root_t
/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

look at all those paths, she's thorough 🎀

💖 FILE CONTEXTS 💖

SELinux requires files to have an extended attribute to define the file type. it's giving "everything has a label, no exceptions."

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the eventlogd, 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 eventlogd_exec_t '/srv/eventlogd/content(/.*)?'
restorecon -R -v /srv/myeventlogd_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 eventlogd:

🍓 eventlogd_exec_t

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

Paths:

/usr/bin/eventlogd, /opt/likewise/sbin/eventlogd

🍓 eventlogd_var_lib_t

  • Set files with the eventlogd_var_lib_t type, if you want to store the eventlogd files under the /var/lib directory.

Paths:

/var/lib/likewise/db/lwi_events.db, /var/lib/likewise-
open/db/lwi_events.db

(that line break in /var/lib/likewise-open/db/lwi_events.db is literally in the original, we keep it fr fr)

🍓 eventlogd_var_run_t

  • Set files with the eventlogd_var_run_t type, if you want to store the eventlogd files under the /run or /var/run directory.

🍓 eventlogd_var_socket_t

  • Set files with the eventlogd_var_socket_t type, if you want to treat the files as eventlogd var socket data.

Paths:

/var/lib/likewise/.eventlog, /var/lib/likewise/rpc/socket,
/var/lib/likewise-open/.eventlog, /var/lib/likewise-open/rpc/socket
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, know the difference bestie 😭 chcon is the quick fix, semanage fcontext + restorecon is the real glow-up.

🌈 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.

all the tools, one little toolbelt 🧰✨
