dirsrvadmin_selinux(8)

💖 NAME 💖

Okay so this is dirsrvadmin_selinux — the Security Enhanced Linux Policy for the dirsrvadmin processes. That's the vibe. 💅

✨ DESCRIPTION ✨

Security-Enhanced Linux is literally the bodyguard for the dirsrvadmin processes — it secures them via flexible mandatory access control. No cap, these processes run with the dirsrvadmin_t SELinux type. Wanna check if you've got them running? Just execute the ps command with the -Z qualifier, like this:

ps -eZ | grep dirsrvadmin_t

It's that simple, bestie. 🫶

🦋 ENTRYPOINTS 🦋

The dirsrvadmin_t SELinux type can be entered via the shell_exec_t and dirsrvadmin_exec_t file types. The default entrypoint paths for the dirsrvadmin_t domain are literally these:

• /bin/d?ash
• /bin/ksh.*
• /bin/zsh.*
• /usr/bin/d?ash
• /usr/bin/ksh.*
• /usr/bin/zsh.*
• /bin/esh
• /bin/bash
• /bin/fish
• /bin/mksh
• /bin/sash
• /bin/tcsh
• /bin/yash
• /bin/bash2
• /usr/bin/esh
• /sbin/nologin
• /usr/bin/bash
• /usr/bin/fish

• /usr/sbin/restart-ds-admin

That's the whole list, periodt. 🎀

🌸 PROCESS TYPES 🌸

SELinux defines process types (aka domains) for every process running on your system. You can peep the context of a process using the -Z option with ps. Policy governs the access that confined processes have to files. The SELinux dirsrvadmin policy is super flexible, letting users set up their dirsrvadmin processes in the most secure way possible. 💪

The following process types are defined for dirsrvadmin:

• dirsrvadmin_t
• dirsrvadmin_unconfined_script_t
• dirsrvadmin_script_t

Note: You can use semanage permissive -a dirsrvadmin_t to make the process type dirsrvadmin_t permissive. SELinux won't deny access to permissive process types, but the AVC (SELinux denials) messages will still be generated. So it's like a vibe check that still logs the drama. 😭

💅 BOOLEANS 💅

SELinux policy is customizable based on the principle of least access required. The dirsrvadmin policy is extremely flexible and has several booleans that let you manipulate the policy and run dirsrvadmin with the tightest access possible. 🔒

• 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

Slay. ✨

🎀 MANAGED FILES 🎀

The SELinux process type dirsrvadmin_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Just remember: the process's UID still needs to have DAC permissions. No cap. 🧐

• 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
  • /var/run/crm(/.*)?
  • /var/run/cman_.*
  • /var/run/rsctmp(/.*)?
  • /var/run/aisexec.*
  • /var/run/heartbeat(/.*)?
  • /var/run/pcsd-ruby.socket
  • /var/run/corosync-qnetd(/.*)?
  • /var/run/corosync-qdevice(/.*)?
  • /var/run/pcsd.socket
  • /var/run/corosync.pid
  • /var/run/cpglockd.pid
  • /var/run/rgmanager.pid
  • /var/run/cluster/rgmanager.sk
• dirsrvadmin_tmp_t
• root_t
  • /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
  • /
  • /initrd

That's the whole list. I kept all paths exactly. 💖

🧚 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 with ls. Policy governs the access that confined processes have to these files. The SELinux dirsrvadmin policy is super flexible, letting users set up their dirsrvadmin processes in the most secure way possible. 💖

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for dirsrvadmin. If you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling, and then use restorecon to put the labels on disk. Like this:

semanage fcontext -a -t dirsrvadmin_ra_content_t '/srv/mydirsrvadmin_content(/.*)?'
restorecon -R -v /srv/mydirsrvadmin_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. So regex is your bestie here. 🧚

The following file types are defined for dirsrvadmin:

• dirsrvadmin_config_t — Set files with the dirsrvadmin_config_t type if you want to treat the files as dirsrvadmin configuration data, usually stored under the /etc directory.
  • Paths: /etc/dirsrv/dsgw(/.*)?, /etc/dirsrv/admin-serv(/.*)?
• dirsrvadmin_content_t — Set files with the dirsrvadmin_content_t type if you want to treat the files as dirsrvadmin content.
  • Paths: (none listed)
• dirsrvadmin_exec_t — Set files with the dirsrvadmin_exec_t type if you want to transition an executable to the dirsrvadmin_t domain.
  • Paths: /usr/sbin/stop-ds-admin, /usr/sbin/start-ds-admin, /usr/sbin/restart-ds-admin
• dirsrvadmin_htaccess_t — Set files with the dirsrvadmin_htaccess_t type if you want to treat the file as a dirsrvadmin access file.
  • Paths: (none listed)
• dirsrvadmin_lock_t — Set files with the dirsrvadmin_lock_t type if you want to treat the files as dirsrvadmin lock data, stored under the /var/lock directory
  • Paths: (none listed)
• dirsrvadmin_ra_content_t — Set files with the dirsrvadmin_ra_content_t type if you want to treat the files as dirsrvadmin read/append content.
  • Paths: (none listed)
• dirsrvadmin_rw_content_t — Set files with the dirsrvadmin_rw_content_t type if you want to treat the files as dirsrvadmin read/write content.
  • Paths: (none listed)
• dirsrvadmin_script_exec_t — Set files with the dirsrvadmin_script_exec_t type if you want to transition an executable to the dirsrvadmin_script_t domain.
  • Paths: /usr/lib/dirsrv/cgi-bin(/.*)?, /usr/lib/dirsrv/dsgw-cgi-bin(/.*)?
• dirsrvadmin_tmp_t — Set files with the dirsrvadmin_tmp_t type if you want to store dirsrvadmin temporary files in the /tmp directories.
  • Paths: (none listed)
• dirsrvadmin_unconfined_script_exec_t — Set files with the dirsrvadmin_unconfined_script_exec_t type if you want to transition an executable to the dirsrvadmin_unconfined_script_t domain.
  • Paths: /usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-bin/ds_remove
• dirsrvadmin_unit_file_t — Set files with the dirsrvadmin_unit_file_t type if you want to treat the files as dirsrvadmin unit content.
  • Paths: (none listed)

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 don't forget that step, bestie! 💅

👑 COMMANDS 👑

Here are some commands that are also super useful:

• 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.

Use them wisely, queen. 👑
