ctdbd_selinux(8)	     SELinux Policy ctdbd	      ctdbd_selinux(8)

NAME
       ctdbd_selinux - Security Enhanced Linux Policy for the ctdbd processes

DESCRIPTION
       Security-Enhanced Linux secures the ctdbd processes via flexible manda‐
       tory access control.

       The ctdbd processes execute with the  ctdbd_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 ctdbd_t

ENTRYPOINTS
       The ctdbd_t SELinux type can be entered via the ctdbd_exec_t file type.

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

       /usr/sbin/ctdbd

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
       ctdbd policy is very flexible allowing users to setup their ctdbd  pro‐
       cesses in as secure a method as possible.

       The following process types are defined for ctdbd:

       ctdbd_t

       Note:  semanage	permissive  -a ctdbd_t can be used to make the process
       type ctdbd_t permissive. SELinux does not  deny	access	to  permissive
       process	types, but the AVC (SELinux denials) messages are still gener‐
       ated.

BOOLEANS
       SELinux policy is customizable based on least access  required.	 ctdbd
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run ctdbd with the tightest access possible.

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 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

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

PORT TYPES
       SELinux 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	ctdbd  policy  is  very flexible allowing users to setup their
       ctdbd processes in as secure a method as possible.

       The following port types are defined for ctdbd:

       ctdb_port_t

       Default Defined Ports:
		 tcp 4379
		 udp 4379

MANAGED FILES
       The SELinux process type ctdbd_t can manage files labeled with the fol‐
       lowing  file  types.   The paths listed are the default paths for these
       file types.  Note the processes UID still need to have DAC permissions.

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

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the ctdbd, 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 ctdbd_exec_t '/srv/ctdbd/content(/.*)?'
       restorecon -R -v /srv/myctdbd_content

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

       The following file types are defined for ctdbd:

       ctdbd_exec_t

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

       ctdbd_initrc_exec_t

       - Set files with the ctdbd_initrc_exec_t type, if you want  to  transi‐
       tion an executable to the ctdbd_initrc_t domain.

       ctdbd_log_t

       - Set files with the ctdbd_log_t type, if you want to treat the data as
       ctdbd log data, usually stored under the /var/log directory.

       Paths:
	    /var/log/ctdb.log.*, /var/log/log.ctdb.*

       ctdbd_spool_t

       - Set files with the ctdbd_spool_t type, if you want to store the ctdbd
       files under the /var/spool directory.

       ctdbd_tmp_t

       -  Set files with the ctdbd_tmp_t type, if you want to store ctdbd tem‐
       porary files in the /tmp directories.

       ctdbd_var_lib_t

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

       ctdbd_var_run_t

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

       ctdbd_var_t

       - Set files with the ctdbd_var_t type, if you want to store the c files
       under the /var 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 data‐
       base.  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  pol‐
       icy 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 pol‐
       icy settings.
