NAMEconntrackd_selinux − Security Enhanced Linux Policy for the conntrackd processes
DESCRIPTIONSecurity-Enhanced Linux secures the conntrackd processes via flexible mandatory access control. The conntrackd processes execute with the conntrackd_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 conntrackd_t
ENTRYPOINTSThe conntrackd_t SELinux type can be entered via the conntrackd_exec_t file type. The default entrypoint paths for the conntrackd_t domain are the following: /usr/sbin/conntrackd
PROCESS TYPESSELinux 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 conntrackd policy is very flexible allowing users to setup their conntrackd processes in as secure a method as possible. The following process types are defined for conntrackd: conntrackd_tNote: semanage permissive -a conntrackd_t can be used to make the process type conntrackd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. conntrackd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run conntrackd 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
PORT TYPESSELinux 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 conntrackd policy is very flexible allowing users to setup their conntrackd processes in as secure a method as possible. The following port types are defined for conntrackd: conntrackd_port_t
Default Defined Ports: udp 3780
MANAGED FILESThe SELinux process type conntrackd_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.

FILE CONTEXTSSELinux 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 conntrackd policy is very flexible allowing users to setup their conntrackd processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the conntrackd, 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 conntrackd_var_lock_t '/srv/myconntrackd_content(/.*)?'
restorecon -R -v /srv/myconntrackd_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for conntrackd: conntrackd_conf_t- Set files with the conntrackd_conf_t type, if you want to treat the files as conntrackd configuration data, usually stored under the /etc directory. conntrackd_exec_t- Set files with the conntrackd_exec_t type, if you want to transition an executable to the conntrackd_t domain. conntrackd_initrc_exec_t- Set files with the conntrackd_initrc_exec_t type, if you want to transition an executable to the conntrackd_initrc_t domain. conntrackd_log_t- Set files with the conntrackd_log_t type, if you want to treat the data as conntrackd log data, usually stored under the /var/log directory. conntrackd_unit_file_t- Set files with the conntrackd_unit_file_t type, if you want to treat the files as conntrackd unit content. conntrackd_var_lock_t- Set files with the conntrackd_var_lock_t type, if you want to treat the files as conntrackd var lock data, stored under the /var/lock directory conntrackd_var_run_t- Set files with the conntrackd_var_run_t type, if you want to store the conntrackd 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.
COMMANDSsemanage 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.
