✨ mysqlmanagerd_selinux β€” the SELinux glow-up for mysqlmanagerd ✨

Okay so bestie, this page is from the mysqlmanagerd_selinux manual, section 8, and it's literally all about how Security-Enhanced Linux keeps the mysqlmanagerd processes in check. No cap, it's giving mandatory access control but make it secure πŸ’…


πŸ’– NAME πŸ’–

mysqlmanagerd_selinux β€” the Security Enhanced Linux Policy for the mysqlmanagerd processes, periodt.


🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the mysqlmanagerd processes via flexible mandatory access control. It's honestly iconic how it just does that.

The mysqlmanagerd processes execute with the mysqlmanagerd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. It's literally that easy, bestie.

For example:

ps -eZ | grep mysqlmanagerd_t

πŸ¦‹ ENTRYPOINTS πŸ¦‹

The mysqlmanagerd_t SELinux type can be entered via the mysqlmanagerd_exec_t file type. That's the main character energy right there.

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

/usr/bin/mysqlmanager

🌈 PROCESS TYPES 🌈

SELinux defines process types (domains) for each process running on the system. Love that for us.

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

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

The following process types are defined for mysqlmanagerd:

mysqlmanagerd_t
Note: semanage permissive -a mysqlmanagerd_t can be used to make the process type mysqlmanagerd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's not a free pass, just a vibe check that logs everything πŸ™ˆ

πŸŽ€ BOOLEANS πŸŽ€

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

  • If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. It's enabled by default, no biggie.
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. Also enabled by default, we love a consistent queen.
setsebool -P fips_mode 1

πŸ”₯ PORT TYPES πŸ”₯

SELinux defines port types to represent TCP and UDP ports. It's giving organized.

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

The following port types are defined for mysqlmanagerd:

mysqlmanagerd_port_t

Default Defined Ports:

tcp 2273

That's the port, bestie. Remember it. πŸ’…


πŸ’œ MANAGED FILES πŸ’œ

The SELinux process type mysqlmanagerd_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 β€” so like, don't forget the basics, okay?

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

mysqlmanagerd_var_run_t

/run/mysqld/mysqlmanager.*

root_t

/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. It's a whole thing, but it's for our own good.

You can see the context of a file using the -Z option to ls. Bestie, use it.

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the mysqlmanagerd. 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. It's giving "customization is key."

semanage fcontext -a -t mysqlmanagerd_exec_t
'/srv/mysqlmanagerd/content(/.*)?'
restorecon -R -v /srv/mymysqlmanagerd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. So yes, regex is here too, because why not.

The following file types are defined for mysqlmanagerd:

  • mysqlmanagerd_exec_t β€” Set files with the mysqlmanagerd_exec_t type, if you want to transition an executable to the mysqlmanagerd_t domain.
  • mysqlmanagerd_initrc_exec_t β€” Set files with the mysqlmanagerd_initrc_exec_t type, if you want to transition an executable to the mysqlmanagerd_initrc_t domain.
  • mysqlmanagerd_var_run_t β€” Set files with the mysqlmanagerd_var_run_t type, if you want to store the mysqlmanagerd 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. So like, chcon is the quick fix, semanage + restorecon is the commitment. Choose wisely πŸ’…

🌟 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.

All the tools you need to live your best SELinux life, honestly.
