NAMEfsdaemon_selinux − Security Enhanced Linux Policy for the fsdaemon processes
DESCRIPTIONSecurity-Enhanced Linux secures the fsdaemon processes via flexible mandatory access control. The fsdaemon processes execute with the fsdaemon_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 fsdaemon_t
ENTRYPOINTSThe fsdaemon_t SELinux type can be entered via the fsdaemon_exec_t file type. The default entrypoint paths for the fsdaemon_t domain are the following: /usr/sbin/smartd
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 fsdaemon policy is very flexible allowing users to setup their fsdaemon processes in as secure a method as possible. The following process types are defined for fsdaemon: fsdaemon_tNote: semanage permissive -a fsdaemon_t can be used to make the process type fsdaemon_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. fsdaemon policy is extremely flexible and has several booleans that allow you to manipulate the policy and run fsdaemon 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
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 determine whether smartmon can support devices on 3ware controllers, you must turn on the smartmon_3ware boolean. Disabled by default. setsebool -P smartmon_3ware 1
If you want to allow confined virtual guests to manage nfs files, you must turn on the virt_use_nfs boolean. Disabled by default. setsebool -P virt_use_nfs 1
If you want to allow confined virtual guests to manage cifs files, you must turn on the virt_use_samba boolean. Disabled by default. setsebool -P virt_use_samba 1
MANAGED FILESThe SELinux process type fsdaemon_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 fsdaemon policy is very flexible allowing users to setup their fsdaemon processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the fsdaemon, 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 fsdaemon_tmp_t '/srv/myfsdaemon_content(/.*)?'
restorecon -R -v /srv/myfsdaemon_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for fsdaemon: fsdaemon_exec_t- Set files with the fsdaemon_exec_t type, if you want to transition an executable to the fsdaemon_t domain. fsdaemon_initrc_exec_t- Set files with the fsdaemon_initrc_exec_t type, if you want to transition an executable to the fsdaemon_initrc_t domain. fsdaemon_tmp_t- Set files with the fsdaemon_tmp_t type, if you want to store fsdaemon temporary files in the /tmp directories. fsdaemon_var_lib_t- Set files with the fsdaemon_var_lib_t type, if you want to store the fsdaemon files under the /var/lib directory. fsdaemon_var_run_t- Set files with the fsdaemon_var_run_t type, if you want to store the fsdaemon 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 boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
