💅 openhpid_selinux — bestie's guide to the SELinux policy for openhpid

okay so. this is openhpid_selinux(8) from the openhpid manual, and it's literally your cheat sheet for how SELinux locks down the openhpid processes. no cap, it's a lot of paths, but we're gonna get through it together 🫶

✨ NAME ✨

openhpid_selinux — the Security Enhanced Linux Policy for the openhpid processes. that's it, that's the whole vibe 💅

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the openhpid processes via flexible mandatory access control. like, it's the bouncer at the club and it is not letting just anyone in.

The openhpid processes execute with the openhpid_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 openhpid_t

🎀 ENTRYPOINTS 🎀

The openhpid_t SELinux type can be entered via the openhpid_exec_t file type.

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

/usr/bin/openhpid

one singular path. iconic, honestly 💅

🦋 PROCESS TYPES 🦋

SELinux defines process types (domains) for each process running on the system — think of a domain as the little outfit a process wears while it's out in public.

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

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

The following process types are defined for openhpid:

  • openhpid_t
Note: semanage permissive -a openhpid_t can be used to make the process type openhpid_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 but it still tells on you 😭

🔥 BOOLEANS 🔥

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

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

🧚 PORT TYPES 🧚

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for openhpid:

  • openhpid_port_t

Default Defined Ports:

tcp 4743
udp 4743

4743 on both, matching set, we love a coordinated moment 💖

👑 MANAGED FILES 👑

The SELinux process type openhpid_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 — SELinux said "yes" but regular file permissions can still say "no" 🙈

  • 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
  • openhpid_log_t
/var/log/dynsim[0-9]*.log
  • openhpid_var_lib_t
/var/lib/openhpi(/.*)?
  • openhpid_var_run_t
/run/openhpid.pid
  • root_t
/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp
  • snmpd_var_lib_t
/var/agentx(/.*)?
/var/net-snmp(/.*)
/var/lib/snmp(/.*)?
/var/net-snmp(/.*)?
/var/lib/net-snmp(/.*)?
/var/spool/snmptt(/.*)?
/usr/share/snmp/mibs/.index

(yes, snmpd_var_lib_t lists /var/net-snmp(/.*) twice. that's what the page says, so that's what you get, fr fr, i don't make the rules 💀)

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the openhpid. 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 openhpid_exec_t '/srv/openhpid/content(/.*)?'
restorecon -R -v /srv/myopenhpid_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for openhpid:

  • openhpid_exec_t — Set files with the openhpid_exec_t type, if you want to transition an executable to the openhpid_t domain.
  • openhpid_initrc_exec_t — Set files with the openhpid_initrc_exec_t type, if you want to transition an executable to the openhpid_initrc_t domain.
  • openhpid_log_t — Set files with the openhpid_log_t type, if you want to treat the data as openhpid log data, usually stored under the /var/log directory.
  • openhpid_var_lib_t — Set files with the openhpid_var_lib_t type, if you want to store the openhpid files under the /var/lib directory.
  • openhpid_var_run_t — Set files with the openhpid_var_run_t type, if you want to store the openhpid files under the /run or /var/run directory.
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. tl;dr chcon is the temporary tattoo, semanage fcontext + restorecon is the real one 💅

💜 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 port can also be used to manipulate the port definitions.
  • semanage boolean can also be used to manipulate the booleans.
  • system-config-selinux is a GUI tool available to customize SELinux policy settings. for when you want buttons instead of flags 🎀
