NAME
       foghorn_selinux	-  Security Enhanced Linux Policy for the foghorn pro‐
       cesses

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

       The  foghorn processes execute with the foghorn_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 foghorn_t

ENTRYPOINTS
       The  foghorn_t  SELinux type can be entered via the foghorn_exec_t file
       type.

       The default entrypoint paths for the foghorn_t domain are  the  follow‐
       ing:

       /usr/sbin/foghorn

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

       The following process types are defined for foghorn:

       foghorn_t

       Note: semanage permissive -a foghorn_t can be used to make the  process
       type  foghorn_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.  foghorn
       policy is extremely flexible and has several booleans that allow you to
       manipulate  the	policy and run foghorn with the tightest access possi‐
       ble.

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow cluster administrative cluster  domains  memcheck-
       amd64-	to   use  executable  memory,  you  must  turn	on  the	 clus‐
       ter_use_execmem boolean. Disabled by default.

       setsebool -P cluster_use_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 run with kerberos, you
       must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 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

       If  you	want to allow confined applications to use nscd shared memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then using a sssd server for the foghorn_t, you must turn
       on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       foghorn_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The  SELinux  process  type foghorn_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 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	foghorn	 policy is very flexible allowing users to setup their
       foghorn processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the foghorn, 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 foghorn_exec_t '/srv/foghorn/content(/.*)?'
       restorecon -R -v /srv/myfoghorn_content

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

       The following file types are defined for foghorn:

       foghorn_exec_t

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

       foghorn_initrc_exec_t

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

       foghorn_tmpfs_t

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

       foghorn_var_log_t

       -  Set  files with the foghorn_var_log_t type, if you want to treat the
       data as foghorn var log data, usually stored under the /var/log	direc‐
       tory.

       foghorn_var_run_t

       -  Set  files with the foghorn_var_run_t type, if you want to store the
       foghorn files under the /run or /var/run 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 boolean can also be used to manipulate the booleans

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