NAME¶

pingd_selinux - Security Enhanced Linux Policy for the pingd processes

DESCRIPTION¶

Security-Enhanced Linux secures the pingd processes via flexible mandatory access control.

The pingd processes execute with the pingd_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 pingd_t

ENTRYPOINTS¶

The pingd_t SELinux type can be entered via the pingd_exec_t file type.

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

/usr/sbin/pingd

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 pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible.

The following process types are defined for pingd:

ping_t, pingd_t

Note: semanage permissive -a pingd_t can be used to make the process type pingd_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. pingd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pingd 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 authlogin_nsswitch_use_ldap boolean. Disabled by default.

setsebool -P authlogin_nsswitch_use_ldap 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 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. Enabled by default.

setsebool -P nscd_use_shm 1

PORT TYPES¶

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for pingd:

pingd_port_t

Default Defined Ports: tcp 9125

MANAGED FILES¶

The SELinux process type pingd_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.

cluster_conf_t

/etc/cluster(/.*)?

cluster_var_lib_t

/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?

cluster_var_run_t

/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*
/var/run/heartbeat(/.*)?
/var/run/pcsd-ruby.socket
/var/run/corosync-qnetd(/.*)?
/var/run/corosync-qdevice(/.*)?
/var/run/corosync.pid
/var/run/cpglockd.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk

root_t

/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd

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 pingd policy is very flexible allowing users to setup their pingd processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the pingd, 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 pingd_modules_t '/srv/mypingd_content(/.*)?'
restorecon -R -v /srv/mypingd_content

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

The following file types are defined for pingd:

pingd_etc_t

- Set files with the pingd_etc_t type, if you want to store pingd files in the /etc directories.

pingd_exec_t

- Set files with the pingd_exec_t type, if you want to transition an executable to the pingd_t domain.

pingd_initrc_exec_t

- Set files with the pingd_initrc_exec_t type, if you want to transition an executable to the pingd_initrc_t domain.

pingd_modules_t

- Set files with the pingd_modules_t type, if you want to treat the files as pingd modules.

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 port can also be used to manipulate the port definitions

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
