✨ lwsmd_selinux ✨

okay bestie, so this is the whole vibe for lwsmd_selinux(8) — it's giving "SELinux policy for the lwsmd processes" and honestly it's a lot but we're gonna get through it together 💖

💅 NAME

lwsmd_selinux — Security Enhanced Linux Policy for the lwsmd processes. periodt.

🌸 DESCRIPTION

Security-Enhanced Linux secures the lwsmd processes via flexible mandatory access control. like, it's literally the bodyguard for these processes, no cap.

The lwsmd processes execute with the lwsmd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier — that's the magic little flag that shows you the security context, iykyk.

For example:

ps -eZ | grep lwsmd_t

🦋 ENTRYPOINTS

The lwsmd_t SELinux type can be entered via the lwsmd_exec_t file type. that's the doorway bestie 🚪✨

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

/usr/bin/lwsmd
/opt/likewise/sbin/lwsmd

🔥 PROCESS TYPES

SELinux defines process types (domains) for each process running on the system — it's very "everyone gets their own little labeled bubble" vibes.

You can see the context of a process using the -Z option to ps. literally so useful, highly recommend.

Policy governs the access confined processes have to files. SELinux lwsmd policy is very flexible allowing users to setup their lwsmd processes in as secure a method as possible. like, choose your own adventure but make it security 🔐

The following process types are defined for lwsmd:

  • lwsmd_t
Note: semanage permissive -a lwsmd_t can be used to make the process type lwsmd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, you're not blocking anything but the receipts are still there 💀

🎀 BOOLEANS

SELinux policy is customizable based on least access required. lwsmd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run lwsmd with the tightest access possible. it's giving "customize your own security journey" ✨

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

🧚 MANAGED FILES

The SELinux process type lwsmd_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 is powerful but it's not out here doing DAC's job, okurrr 💅

  • cluster_conf_t
/etc/cluster(/.*)?
  • cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?

👑 FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type. yes bestie, every file gets a little label, it's their whole personality 🏷️

You can see the context of a file using the -Z option to ls. again with the -Z! it's the star of the show.

Policy governs the access confined processes have to these files. SELinux lwsmd policy is very flexible allowing users to setup their lwsmd processes in as secure a method as possible. we stan flexibility 💜

⭐ STANDARD FILE CONTEXT

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

The following file types are defined for lwsmd:

  • lwsmd_exec_t — Set files with the lwsmd_exec_t type, if you want to transition an executable to the lwsmd_t domain.

Paths:

/usr/bin/lwsmd
/opt/likewise/sbin/lwsmd
  • lwsmd_var_lib_t — Set files with the lwsmd_var_lib_t type, if you want to store the lwsmd files under the /var/lib directory.

Paths:

/var/lib/likewise/.lwsmd-lock
/var/lib/likewise-open/.lwsmd-lock
  • lwsmd_var_run_t — Set files with the lwsmd_var_run_t type, if you want to store the lwsmd files under the /run or /var/run directory.
  • lwsmd_var_socket_t — Set files with the lwsmd_var_socket_t type, if you want to treat the files as lwsmd var socket data.

Paths:

/var/lib/likewise/.lwsm
/var/lib/likewise-open/.lwsm
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 and semanage fcontext + restorecon is the permanent glow-up, periodt 💅✨

🌈 COMMANDS

semanage fcontext can also be used to manipulate default file context mappings. iconic.

semanage permissive can also be used to manipulate whether or not a process type is permissive. we love a flexible queen.

semanage module can also be used to enable/disable/install/remove policy modules. the multitasker of the group chat.

semanage boolean can also be used to manipulate the booleans. booleans are literally the on/off switches of SELinux vibes.

system-config-selinux is a GUI tool available to customize SELinux policy settings. for the besties who prefer a visual moment 🖥️✨
