NAME

       chroot_user_selinux - Security Enhanced Linux Policy for the chroot_user processes

DESCRIPTION

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

       The  chroot_user  processes execute with the chroot_user_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 chroot_user_t

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

       The following process types are defined for chroot_user:

       chroot_user_t

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

       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 ssh with chroot env to read and write files in the user home directories, you must turn on the ssh_chroot_rw_homedirs
       boolean. Disabled by default.

       setsebool -P ssh_chroot_rw_homedirs 1

       If you want to support ecryptfs home directories, you must turn on the use_ecryptfs_home_dirs boolean. Disabled by default.

       setsebool -P use_ecryptfs_home_dirs 1

       If you want to support fusefs home directories, you must turn on the use_fusefs_home_dirs boolean. Disabled by default.

       setsebool -P use_fusefs_home_dirs 1

       If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

       setsebool -P use_nfs_home_dirs 1

       If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

       setsebool -P use_samba_home_dirs 1

MANAGED FILES

       The SELinux process type chroot_user_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.

       cifs_t

       ecryptfs_t

	    /home/[^/]*/.Private(/.*)?
	    /home/[^/]*/.ecryptfs(/.*)?

       fusefs_t

	    /var/run/[^/]*/gvfs

       nfs_t

       user_home_t

	    /home/[^/]*/.+

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 policy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
