💅 pkcs_slotd_selinux(8)

okay so bestie, welcome to pkcs_slotd_selinux — this is the manual page for the SELinux Policy for the pkcs_slotd processes, and yes it's giving "niche but iconic" ✨ (the manual page itself is pkcs_slotd_selinux(8), filing that here so we're all on the same page 🎀)

✨ NAME ✨

pkcs_slotd_selinux — the Security Enhanced Linux Policy for the pkcs_slotd processes, no cap 🫶

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the pkcs_slotd processes via flexible mandatory access control. Literally the whole point. 👑

The pkcs_slotd processes execute with the pkcs_slotd_t SELinux type. Wanna check if you've got these processes running? Just execute the ps command with the -Z qualifier.

For example:

ps -eZ | grep pkcs_slotd_t

easy as that, you ate 💅

🦋 ENTRYPOINTS 🦋

The pkcs_slotd_t SELinux type can be entered via the pkcs_slotd_exec_t file type. That's the doorway, iykyk 🚪✨

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

/usr/bin/pkcsslotd

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. So every process gets its own little vibe check 🧚

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

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

The following process types are defined for pkcs_slotd:

pkcs_slotd_t

Note: semanage permissive -a pkcs_slotd_t can be used to make the process type pkcs_slotd_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's still gonna gossip about you in the logs 😭💀

🍓 BOOLEANS 🍓

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

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

If you want to allow httpd to use opencryptoki, you must turn on the httpd_use_opencryptoki boolean. Disabled by default.

setsebool -P httpd_use_opencryptoki 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

🎀 MANAGED FILES 🎀

The SELinux process type pkcs_slotd_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'll handle the labels" but UID said "not my problem" 🙈)

🌈 FILE CONTEXTS 🌈

SELinux requires files to have an extended attribute to define the file type. like a little name tag but for files 🏷️✨

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

💖 STANDARD FILE CONTEXT 💖

SELinux defines the file context types for the pkcs_slotd. 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 pkcs_slotd_exec_t
'/srv/pkcs_slotd/content(/.*)?'
restorecon -R -v /srv/mypkcs_slotd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🙌

The following file types are defined for pkcs_slotd:

  • pkcs_slotd_exec_t — Set files with the pkcs_slotd_exec_t type, if you want to transition an executable to the pkcs_slotd_t domain.
  • pkcs_slotd_initrc_exec_t — Set files with the pkcs_slotd_initrc_exec_t type, if you want to transition an executable to the pkcs_slotd_initrc_t domain.
  • pkcs_slotd_lock_t — Set files with the pkcs_slotd_lock_t type, if you want to treat the files as pkcs slotd lock data, stored under the /var/lock directory.
  • pkcs_slotd_log_t — Set files with the pkcs_slotd_log_t type, if you want to treat the data as pkcs slotd log data, usually stored under the /var/log directory.
  • pkcs_slotd_tmp_t — Set files with the pkcs_slotd_tmp_t type, if you want to store pkcs slotd temporary files in the /tmp directories.
  • pkcs_slotd_tmpfs_t — Set files with the pkcs_slotd_tmpfs_t type, if you want to store pkcs slotd files on a tmpfs file system.
  • pkcs_slotd_unit_file_t — Set files with the pkcs_slotd_unit_file_t type, if you want to treat the files as pkcs slotd unit content.
  • pkcs_slotd_var_lib_t — Set files with the pkcs_slotd_var_lib_t type, if you want to store the pkcs slotd files under the /var/lib directory.
  • pkcs_slotd_var_run_t — Set files with the pkcs_slotd_var_run_t type, if you want to store the pkcs slotd files under the /run or /var/run directory.

Paths:

/run/pkcsslotd.*, /run/opencryptoki(/.*)?
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 chcon is the "for now" girlie and semanage fcontext + restorecon is the "forever" girlie 💍

⭐ 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. (yes a GUI, for when the terminal vibe isn't it 💅)
