✨ openwsman_selinux 💅 — the manual page for the openwsman SELinux policy ✨

okay bestie, so this is the openwsman_selinux manual page — yes, the one from the SELinux Policy openwsman section, and it's literally all about keeping the openwsman processes safe and sound under Security-Enhanced Linux. 🎀

🌸 NAME 🌸

openwsman_selinux — the Security Enhanced Linux Policy for the openwsman processes. that's the whole vibe. 🫶

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the openwsman processes via flexible mandatory access control. no cap, that's the whole point.

The openwsman processes execute with the openwsman_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. like so:

ps -eZ | grep openwsman_t

go ahead, run it. i'll wait. 💅

🚪 ENTRYPOINTS 🚪

The openwsman_t SELinux type can be entered via the openwsman_exec_t file type. it's giving "one door, one destiny" honestly. ✨

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

/usr/bin/openwsmand

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. yes, every single one gets its own little domain. main character energy fr fr. 🎀

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

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

The following process types are defined for openwsman:

  • openwsman_t
Note: semanage permissive -a openwsman_t can be used to make the process type openwsman_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so it's chill but it's still watching you. 🙈

🎚️ BOOLEANS 🎚️

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

  • daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default.
setsebool -P daemons_dontaudit_scheduling 1
  • deny_execmem — if you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on this boolean. Disabled by default.
setsebool -P deny_execmem 1
  • mmap_low_allowed — if you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on this boolean. Disabled by default.
setsebool -P mmap_low_allowed 1
  • nis_enabled — if you want to allow system to run with NIS, you must turn on this boolean. Disabled by default.
setsebool -P nis_enabled 1
  • secure_mode_insmod — if you want to disable kernel module loading, you must turn on this boolean. Disabled by default.
setsebool -P secure_mode_insmod 1
  • selinuxuser_execheap — if you want to allow unconfined executables to make their heap memory executable. doing this is a really bad idea. probably indicates a badly coded executable, but could indicate an attack. this executable should be reported in bugzilla, you must turn on this boolean. Disabled by default.
setsebool -P selinuxuser_execheap 1
  • selinuxuser_execstack — if you want to allow unconfined executables to make their stack executable. this should never, ever be necessary. probably indicates a badly coded executable, but could indicate an attack. this executable should be reported in bugzilla, you must turn on this boolean. Disabled by default.
setsebool -P selinuxuser_execstack 1

📂 MANAGED FILES 📂

The SELinux process type openwsman_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 isn't doing all the work, bestie.
  • file_type — all files on the system

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. it's 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 openwsman policy is very flexible, allowing users to setup their openwsman processes in as secure a method as possible.

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for openwsman. 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. slay.

semanage fcontext -a -t openwsman_exec_t '/srv/openwsman/content(/.*)?'
restorecon -R -v /srv/myopenwsman_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise. 💅

The following file types are defined for openwsman:

  • openwsman_exec_t — set files with the openwsman_exec_t type if you want to transition an executable to the openwsman_t domain.
  • openwsman_log_t — set files with the openwsman_log_t type if you want to treat the data as openwsman log data, usually stored under the /var/log directory.
  • openwsman_run_t — set files with the openwsman_run_t type if you want to treat the files as openwsman run data.
  • openwsman_tmp_t — set files with the openwsman_tmp_t type if you want to store openwsman temporary files in the /tmp directories.
  • openwsman_tmpfs_t — set files with the openwsman_tmpfs_t type if you want to store openwsman files on a tmpfs file system.
  • openwsman_unit_file_t — set files with the openwsman_unit_file_t type if you want to treat the files as openwsman unit content.
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. 😭

🛠️ 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.
