NAME
       boinc_selinux - Security Enhanced Linux Policy for the boinc processes

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

       The boinc processes execute with the  boinc_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 boinc_t

ENTRYPOINTS
       The boinc_t SELinux type can be entered via the boinc_exec_t file type.

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

       /usr/bin/boinc_client

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

       The following process types are defined for boinc:

       boinc_t, boinc_project_t

       Note:  semanage	permissive  -a boinc_t can be used to make the process
       type boinc_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.	 boinc
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run boinc with the tightest access possible.

       If you want to allow boinc_domain execmem/execstack, you must  turn  on
       the boinc_execmem boolean. Enabled by default.

       setsebool -P boinc_execmem 1

       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 confined applications to use nscd  shared  memory,
       you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 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	boinc  policy  is  very flexible allowing users to setup their
       boinc processes in as secure a method as possible.

       The following port types are defined for boinc:

       boinc_client_port_t

       Default Defined Ports:
		 tcp 1043
		 udp 1034

       boinc_port_t

       Default Defined Ports:
		 tcp 31416

MANAGED FILES
       The SELinux process type boinc_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.

       boinc_log_t

	    /var/log/boinc.log.*

       boinc_project_var_lib_t

	    /var/lib/boinc/slots(/.*)?
	    /var/lib/boinc/projects(/.*)?

	    /var/run/cluster/rgmanager.sk

       root_t

	    /
	    /initrd

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

       EQUIVALENCE DIRECTORIES

       boinc  policy  stores  data  with multiple different file context types
       under the /var/lib/boinc directory.  If you would  like	to  store  the
       data  in a different directory you can use the semanage command to cre‐
       ate an equivalence mapping.  If you wanted to store this data under the
       /srv dirctory you would execute the following command:

       semanage fcontext -a -e /var/lib/boinc /srv/boinc
       restorecon -R -v /srv/boinc

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the boinc, 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 boinc_exec_t '/srv/boinc/content(/.*)?'
       restorecon -R -v /srv/myboinc_content

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

       The following file types are defined for boinc:

       boinc_exec_t

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

       boinc_initrc_exec_t

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

       boinc_log_t

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

       boinc_project_tmp_t

       - Set files with the boinc_project_tmp_t type, if  you  want  to	 store
       boinc project temporary files in the /tmp directories.

       boinc_project_var_lib_t

       - Set files with the boinc_project_var_lib_t type, if you want to store
       the boinc project files under the /var/lib directory.

       Paths:
	    /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?

       boinc_tmp_t

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

       boinc_tmpfs_t

       -  Set  files  with  the boinc_tmpfs_t type, if you want to store boinc
       files on a tmpfs file system.

       boinc_unit_file_t

       - Set files with the boinc_unit_file_t type, if you want to  treat  the
       files as boinc unit content.

       boinc_var_lib_t

       -  Set  files  with  the boinc_var_lib_t type, if you want to store the
       boinc files under the /var/lib 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.
