watchdog_unconfined_seSELinux)Policy watchdog_unwatchdog_unconfined_selinux(8)

NAME
       watchdog_unconfined_selinux  -  Security	 Enhanced Linux Policy for the
       watchdog_unconfined processes

DESCRIPTION
       Security-Enhanced Linux secures the watchdog_unconfined	processes  via
       flexible mandatory access control.

       The  watchdog_unconfined	 processes  execute  with  the watchdog_uncon‐
       fined_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 watchdog_unconfined_t

ENTRYPOINTS
       The  watchdog_unconfined_t SELinux type can be entered via the filesys‐
       tem_type,  unlabeled_t,	proc_type,  file_type,	 sysctl_type,	watch‐
       dog_unconfined_exec_t, mtrr_device_t file types.

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

       all files on  the  system,  /etc/watchdog.d(/.*)?,  /usr/libexec/watch‐
       dog/scripts(/.*)?, /dev/cpu/mtrr

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

       The following process types are defined for watchdog_unconfined:

       watchdog_unconfined_t

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

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

       If you want to deny user domains applications to map a memory region as
       both  executable	 and  writable,	 this  is dangerous and the executable
       should be reported in bugzilla, you must turn on the deny_execmem bool‐
       ean. Enabled by default.

       setsebool -P deny_execmem 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 control the ability to mmap a low area  of  the  address
       space,  as  configured by /proc/sys/kernel/mmap_min_addr, you must turn
       on the mmap_low_allowed boolean. Disabled by default.

       setsebool -P mmap_low_allowed 1

       If you want to disable kernel module loading,  you  must	 turn  on  the
       secure_mode_insmod boolean. Enabled by default.

       setsebool -P secure_mode_insmod 1

       If  you want to boolean to determine whether the system permits loading
       policy, setting enforcing mode, and changing boolean values.  Set  this
       to  true	 and  you  have to reboot to set it back, you must turn on the
       secure_mode_policyload boolean. Enabled by default.

       setsebool -P secure_mode_policyload 1

       If you want to allow unconfined executables to make their  heap	memory
       executable.   Doing  this  is  a	 really bad idea. Probably indicates a
       badly coded executable, but could indicate an attack.  This  executable
       should	be   reported  in  bugzilla,  you  must	 turn  on  the	selin‐
       uxuser_execheap boolean. Disabled by default.

       setsebool -P selinuxuser_execheap 1

       If you want to  allow  all  unconfined  executables  to	use  libraries
       requiring  text	relocation  that  are not labeled textrel_shlib_t, you
       must turn on the selinuxuser_execmod boolean. Enabled by default.

       setsebool -P selinuxuser_execmod 1

       If you want to allow unconfined executables to make  their  stack  exe‐
       cutable.	  This	should	never, ever be necessary. Probably indicates a
       badly coded executable, but could indicate an attack.  This  executable
       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
       stack boolean. Enabled by default.

       setsebool -P selinuxuser_execstack 1

       If you want to support X userspace object manager, you must turn on the
       xserver_object_manager boolean. Enabled by default.

       setsebool -P xserver_object_manager 1

       If  you	want  to allow ZoneMinder to run su/sudo, you must turn on the
       zoneminder_run_sudo boolean. Disabled by default.

       setsebool -P zoneminder_run_sudo 1

MANAGED FILES
       The SELinux process type watchdog_unconfined_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_type

	    all files on the system

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	watchdog_unconfined  policy is very flexible allowing users to
       setup their watchdog_unconfined processes in as secure a method as pos‐
       sible.

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the watchdog_unconfined, 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   watchdog_unconfined_exec_t	  '/srv/watch‐
       dog_unconfined/content(/.*)?'
       restorecon -R -v /srv/mywatchdog_unconfined_content

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

       The following file types are defined for watchdog_unconfined:

       watchdog_unconfined_exec_t

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

       Paths:
	    /etc/watchdog.d(/.*)?, /usr/libexec/watchdog/scripts(/.*)?

       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.
