NAMEthin_selinux − Security Enhanced Linux Policy for the thin processes
DESCRIPTIONSecurity-Enhanced Linux secures the thin processes via flexible mandatory access control. The thin processes execute with the thin_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 thin_t
ENTRYPOINTSThe thin_t SELinux type can be entered via the thin_exec_t file type. The default entrypoint paths for the thin_t domain are the following: /usr/bin/thin
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 thin policy is very flexible allowing users to setup their thin processes in as secure a method as possible. The following process types are defined for thin: thin_t, thin_aeolus_configserver_tNote: semanage permissive -a thin_t can be used to make the process type thin_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. thin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run thin 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 FILESThe SELinux process type thin_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(/.*)?

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 thin policy is very flexible allowing users to setup their thin processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the thin, 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 thin_aeolus_configserver_var_run_t '/srv/mythin_content(/.*)?'
restorecon -R -v /srv/mythin_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for thin: thin_aeolus_configserver_exec_t- Set files with the thin_aeolus_configserver_exec_t type, if you want to transition an executable to the thin_aeolus_configserver_t domain. thin_aeolus_configserver_lib_t- Set files with the thin_aeolus_configserver_lib_t type, if you want to treat the files as thin aeolus configserver lib data. thin_aeolus_configserver_log_t- Set files with the thin_aeolus_configserver_log_t type, if you want to treat the data as thin aeolus configserver log data, usually stored under the /var/log directory. thin_aeolus_configserver_var_run_t- Set files with the thin_aeolus_configserver_var_run_t type, if you want to store the thin aeolus configserver files under the /run or /var/run directory. thin_exec_t- Set files with the thin_exec_t type, if you want to transition an executable to the thin_t domain. thin_log_t- Set files with the thin_log_t type, if you want to treat the data as thin log data, usually stored under the /var/log directory. thin_var_run_t- Set files with the thin_var_run_t type, if you want to store the thin files under the /run or /var/run directory.
Paths: /var/run/thin(/.*)?, /var/run/aeolus/thin.pid 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 boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
