NAME¶

vnstatd_selinux - Security Enhanced Linux Policy for the vnstatd processes

DESCRIPTION¶

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

The vnstatd processes execute with the vnstatd_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 vnstatd_t

ENTRYPOINTS¶

The vnstatd_t SELinux type can be entered via the vnstatd_exec_t file type.

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

/usr/sbin/vnstatd

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

The following process types are defined for vnstatd:

vnstat_t, vnstatd_t

Note: semanage permissive -a vnstatd_t can be used to make the process type vnstatd_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. vnstatd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run vnstatd with the tightest access possible.

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

MANAGED FILES¶

The SELinux process type vnstatd_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

vnstatd_var_lib_t

/var/lib/vnstat(/.*)?

vnstatd_var_run_t

/var/run/vnstat.*

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the vnstatd, 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 vnstatd_var_run_t '/srv/myvnstatd_content(/.*)?'
restorecon -R -v /srv/myvnstatd_content

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

The following file types are defined for vnstatd:

vnstatd_exec_t

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

vnstatd_initrc_exec_t

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

vnstatd_var_lib_t

- Set files with the vnstatd_var_lib_t type, if you want to store the vnstatd files under the /var/lib directory.

vnstatd_var_run_t

- Set files with the vnstatd_var_run_t type, if you want to store the vnstatd 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 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.
