pingd_selinux(8) SELinux Policy pingd pingd_selinux(8)NAMEpingd_selinux - Security Enhanced Linux Policy for the pingd processes
DESCRIPTION
Security-Enhanced Linux secures the pingd processes via flexible manda‐
tory 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 pro‐
cesses 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 gener‐
ated.
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 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 pingd_t, ping_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
pingd_t, ping_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 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 fol‐
lowing 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/cpglockd.pid
/var/run/corosync.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk
root_t
/
/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_etc_t '/srv/pingd/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 transi‐
tion 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 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 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 pol‐
icy settings.
