piranha_pulse_selinux(8) SELinux Policy piranha_pulse piranha_pulse_selinux(8)NAMEpiranha_pulse_selinux - Security Enhanced Linux Policy for the
piranha_pulse processes
DESCRIPTION
Security-Enhanced Linux secures the piranha_pulse processes via flexi‐
ble mandatory access control.
The piranha_pulse processes execute with the piranha_pulse_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 piranha_pulse_t
ENTRYPOINTS
The piranha_pulse_t SELinux type can be entered via the
piranha_pulse_exec_t file type.
The default entrypoint paths for the piranha_pulse_t domain are the
following:
/usr/sbin/pulse
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
piranha_pulse policy is very flexible allowing users to setup their
piranha_pulse processes in as secure a method as possible.
The following process types are defined for piranha_pulse:
piranha_pulse_t
Note: semanage permissive -a piranha_pulse_t can be used to make the
process type piranha_pulse_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.
piranha_pulse policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run piranha_pulse with the
tightest access possible.
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
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 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 allow confined applications to run with kerberos, you
must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 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
If you want to allow confined applications to use nscd shared memory,
you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server for the piranha_pulse_t, you must
turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
piranha_pulse_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type piranha_pulse_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 per‐
missions.

/etc/cluster(/.*)?

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 piranha_pulse policy is very flexible allowing users to setup
their piranha_pulse processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the piranha_pulse, if you
wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then
use restorecon to put the labels on disk.
semanage fcontext -a -t piranha_pulse_exec_t '/srv/piranha_pulse/con‐
tent(/.*)?'
restorecon -R -v /srv/mypiranha_pulse_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for piranha_pulse:
piranha_pulse_exec_t
- Set files with the piranha_pulse_exec_t type, if you want to transi‐
tion an executable to the piranha_pulse_t domain.
piranha_pulse_initrc_exec_t
- Set files with the piranha_pulse_initrc_exec_t type, if you want to
transition an executable to the piranha_pulse_initrc_t domain.
piranha_pulse_tmpfs_t
- Set files with the piranha_pulse_tmpfs_t type, if you want to store
piranha pulse files on a tmpfs file system.
piranha_pulse_var_run_t
- Set files with the piranha_pulse_var_run_t type, if you want to store
the piranha pulse files under the /run or /var/run directory.
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 data‐
base. 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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
