NAME
pegasus_openlmi_unconfined_selinux - Security Enhanced Linux Policy for the pegasus_openlmi_unconfined processes
DESCRIPTION
Security-Enhanced Linux secures the pegasus_openlmi_unconfined processes via flexible mandatory access control.
The pegasus_openlmi_unconfined processes execute with the pegasus_openlmi_unconfined_t SELinux type. You can check if you have these pro-
cesses running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep pegasus_openlmi_unconfined_t
ENTRYPOINTS
The pegasus_openlmi_unconfined_t SELinux type can be entered via the unlabeled_t, proc_type, file_type, mtrr_device_t, filesystem_type,
sysctl_type, pegasus_openlmi_unconfined_exec_t file types.
The default entrypoint paths for the pegasus_openlmi_unconfined_t domain are the following:
all files on the system, /dev/cpu/mtrr
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_unconfined policy is very flexible allowing users to
setup their pegasus_openlmi_unconfined processes in as secure a method as possible.
The following process types are defined for pegasus_openlmi_unconfined:
pegasus_openlmi_unconfined_t
Note: semanage permissive -a pegasus_openlmi_unconfined_t can be used to make the process type pegasus_openlmi_unconfined_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. pegasus_openlmi_unconfined policy is extremely flexible and has several
booleans that allow you to manipulate the policy and run pegasus_openlmi_unconfined with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
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. Enabled by default.
setsebool -P deny_execmem 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/kernel/mmap_min_addr, you must turn
on the mmap_low_allowed boolean. Disabled by default.
setsebool -P mmap_low_allowed 1
If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Enabled by default.
setsebool -P secure_mode_insmod 1
If you want to boolean to determine whether the system permits loading policy, setting enforcing mode, and changing boolean values. Set
this to true and you have to reboot to set it back, you must turn on the secure_mode_policyload boolean. Enabled by default.
setsebool -P secure_mode_policyload 1
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 the selin-
uxuser_execheap boolean. Disabled by default.
setsebool -P selinuxuser_execheap 1
If you want to allow all unconfined executables to use libraries requiring text relocation that are not labeled textrel_shlib_t, you must
turn on the selinuxuser_execmod boolean. Enabled by default.
setsebool -P selinuxuser_execmod 1
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 the selin-
uxuser_execstack boolean. Enabled by default.
setsebool -P selinuxuser_execstack 1
If you want to support X userspace object manager, you must turn on the xserver_object_manager boolean. Enabled by default.
setsebool -P xserver_object_manager 1
If you want to allow ZoneMinder to run su/sudo, you must turn on the zoneminder_run_sudo boolean. Disabled by default.
setsebool -P zoneminder_run_sudo 1
MANAGED FILES
The SELinux process type pegasus_openlmi_unconfined_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
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.
