NAMEsmbcontrol_selinux − Security Enhanced Linux Policy for the smbcontrol processes
DESCRIPTIONSecurity-Enhanced Linux secures the smbcontrol processes via flexible mandatory access control. The smbcontrol processes execute with the smbcontrol_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 smbcontrol_t
ENTRYPOINTSThe smbcontrol_t SELinux type can be entered via the smbcontrol_exec_t file type. The default entrypoint paths for the smbcontrol_t domain are the following: /usr/bin/smbcontrol
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 smbcontrol policy is very flexible allowing users to setup their smbcontrol processes in as secure a method as possible. The following process types are defined for smbcontrol: smbcontrol_tNote: semanage permissive -a smbcontrol_t can be used to make the process type smbcontrol_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. smbcontrol policy is extremely flexible and has several booleans that allow you to manipulate the policy and run smbcontrol 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 smbcontrol_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.
samba_var_t /var/nmbd(/.*)?
/var/lib/samba(/.*)?
/var/cache/samba(/.*)?
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 smbcontrol policy is very flexible allowing users to setup their smbcontrol processes in as secure a method as possible. The following file types are defined for smbcontrol: smbcontrol_exec_t- Set files with the smbcontrol_exec_t type, if you want to transition an executable to the smbcontrol_t domain. 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.
