NAME
       canna_selinux - Security Enhanced Linux Policy for the canna processes

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

       The canna processes execute with the  canna_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 canna_t

ENTRYPOINTS
       The canna_t SELinux type can be entered via the canna_exec_t file type.

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

       /usr/bin/catdic, /usr/sbin/jserver, /usr/bin/cannaping,	/usr/sbin/can‐
       naserver

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

       The following process types are defined for canna:

       canna_t

       Note: semanage permissive -a canna_t can be used to  make  the  process
       type  canna_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.	 canna
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run canna 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

       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

MANAGED FILES
       The SELinux process type canna_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.

	    /var/lib/wnn/dic(/.*)?
	    /var/lib/canna/dic(/.*)?

       canna_var_run_t

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

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the canna, 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 canna_exec_t '/srv/canna/content(/.*)?'
       restorecon -R -v /srv/mycanna_content

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

       The following file types are defined for canna:

       canna_exec_t

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

       Paths:
	    /usr/bin/catdic,	   /usr/sbin/jserver,	   /usr/bin/cannaping,
	    /usr/sbin/cannaserver

       canna_initrc_exec_t

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

       canna_log_t

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

       Paths:
	    /var/log/wnn(/.*)?, /var/log/canna(/.*)?

       canna_var_lib_t

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

       Paths:
	    /var/lib/wnn/dic(/.*)?, /var/lib/canna/dic(/.*)?

       canna_var_run_t

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

       Paths:
	    /var/run/wnn-unix(/.*),		      /var/run/.iroha_unix/.*,
	    /var/run/.iroha_unix

       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 boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
