NAME¶

lldpad_selinux - Security Enhanced Linux Policy for the lldpad processes

DESCRIPTION¶

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

The lldpad processes execute with the lldpad_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 lldpad_t

ENTRYPOINTS¶

The lldpad_t SELinux type can be entered via the lldpad_exec_t file type.

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

/usr/sbin/lldpd, /usr/sbin/lldpad

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

The following process types are defined for lldpad:

lldpad_t

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

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 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

MANAGED FILES¶

The SELinux process type lldpad_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/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?

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

EQUIVALENCE DIRECTORIES

lldpad policy stores data with multiple different file context types under the /var/run/lldpd directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command:

semanage fcontext -a -e /var/run/lldpd /srv/lldpd
restorecon -R -v /srv/lldpd

STANDARD FILE CONTEXT

SELinux defines the file context types for the lldpad, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t lldpad_var_run_t '/srv/mylldpad_content(/.*)?'
restorecon -R -v /srv/mylldpad_content

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

The following file types are defined for lldpad:

lldpad_exec_t

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

Paths:

/usr/sbin/lldpd, /usr/sbin/lldpad

lldpad_initrc_exec_t

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

lldpad_tmpfs_t

- Set files with the lldpad_tmpfs_t type, if you want to store lldpad files on a tmpfs file system.

lldpad_var_lib_t

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

Paths:

/var/lib/lldpd(/.*)?, /var/lib/lldpad(/.*)?

lldpad_var_run_t

- Set files with the lldpad_var_run_t type, if you want to store the lldpad files under the /run or /var/run directory.

Paths:

/var/run/lldpd.*, /var/run/lldpd(/.*)?, /var/run/lldpad.*

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.
