💖 NAME 💖

okay bestie, welcome to pegas...elinux(8) — the SELinux policy page for the pegasus_openlmi_logicalfile processes. This is the manual name folded in right at the top, and we are so ready to get into it. ✨

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the pegasus_openlmi_logicalfile processes via flexible mandatory access control. No cap.

The pegasus_openlmi_logicalfile processes execute with the pegasus_openlmi_logicalfile_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep pegasus_openlmi_logicalfile_t

🦋 ENTRYPOINTS 🦋

The pegasus_openlmi_logicalfile_t SELinux type can be entered via the pegasus_openlmi_logicalfile_exec_t, user_home_t file types.

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

• /usr/libexec/pegasus/cmpiLMI_LogicalFile-cimprovagt
• /home/[^/]+/.+

👑 PROCESS TYPES 👑

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

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

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

The following process types are defined for pegasus_openlmi_logicalfile:

• pegasus_openlmi_logicalfile_t

Note: semanage permissive -a pegasus_openlmi_logicalfile_t can be used to make the process type pegasus_openlmi_logicalfile_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

🍓 BOOLEANS 🍓

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

🍓 daemons_dontaudit_scheduling

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

🍓 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 the deny_execmem 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 the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

🍓 secure_mode_insmod

If you want to disable kernel module loading, you must turn on the secure_mode_insmod 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, and this executable should be reported in bugzilla — you must turn on the selinuxuser_execheap 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, and this executable should be reported in bugzilla — you must turn on the selinuxuser_execstack boolean. Disabled by default.

setsebool -P selinuxuser_execstack 1

🌈 MANAGED FILES 🌈

The SELinux process type pegasus_openlmi_logicalfile_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.

• file_type — all files on the system

🎀 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 to ls.

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

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the pegasus_openlmi_logicalfile. 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.

semanage fcontext -a -t pegasus_openlmi_logicalfile_exec_t '/srv/pegasus_openlmi_logicalfile/content(/.*)?'
restorecon -R -v /srv/mypegasus_openlmi_logicalfile_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for pegasus_openlmi_logicalfile:

• pegasus_openlmi_logicalfile_exec_t — Set files with the pegasus_openlmi_logicalfile_exec_t type if you want to transition an executable to the pegasus_openlmi_logicalfile_t domain.

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.

💅 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.
