failsafe_context(5)					       SELinux configuration					       failsafe_context(5)

NAME

       failsafe_context - The SELinux fail safe context configuration file.

DESCRIPTION

       The failsafe_context file allows SELinux-aware applications such as PAM(8) to obtain a known valid login context for an administrator if no
       valid default entries can be found elsewhere.

       selinux_failsafe_context_path(3) will return the active policy path to this file. The default failsafe context file is:
	      /etc/selinux/{SELINUXTYPE}/contexts/failsafe_context

       Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).

       The following functions read this file from the active policy path if they cannot obtain a default context:
	      get_default_context(3)
	      get_ordered_context_list(3)
	      get_ordered_context_list_with_level(3)
	      get_default_context_with_level(3)
	      get_default_context_with_role(3)
	      get_default_context_with_rolelevel(3)
	      query_user_context(3)
	      manual_user_enter_context(3)

FILE FORMAT

       The file consists of a single line entry as follows:
	      role:type[:range]

       Where:
	      role type range
		     A role, type and optional range (for MCS/MLS), separated by colons (:) to form a valid login process context for an  adminis-
		     trator to access the system.

EXAMPLE

       # ./contexts/failsafe_context
       unconfined_r:unconfined_t:s0

NAME

       user_contexts - The SELinux user contexts configuration files.

DESCRIPTION

       These  optional	user  context  configuration  files contain entries that allow SELinux-aware login applications such as PAM(8) (running in
       their own process context), to determine the context that a users login session should run under.

       SELinux-aware login applications generally use one or more of the following libselinux functions that read these files from the active pol-
       icy path:
	      get_default_context(3)
	      get_ordered_context_list(3)
	      get_ordered_context_list_with_level(3)
	      get_default_context_with_level(3)
	      get_default_context_with_role(3)
	      get_default_context_with_rolelevel(3)
	      query_user_context(3)
	      manual_user_enter_context(3)

       There can be one file for each SELinux user configured on the system. The file  path is formed using the path returned by selinux_user_con-
       texts_path(3) for the active policy, with the SELinux user name appended, for example:
	      /etc/selinux/{SELINUXTYPE}/contexts/users/unconfined_u
	      /etc/selinux/{SELINUXTYPE}/contexts/users/xguest_u

       Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).

       These files contain context information as described in the FILE FORMAT section.

FILE FORMAT

       Each line in the user context configuration file consists of the following:
	      login_process user_login_process

       Where:
	      login_process
		     This consists of a role:type[:range] entry that represents the login process context.
	      user_login_process
		     This consists of a role:type[:range] entry that represents the user login process context.

EXAMPLE

       # Example for xguest_u at /etc/selinux/targeted/contexts/users/xguest_u
       system_r:crond_t:s0	     xguest_r:xguest_t:s0
       system_r:initrc_t:s0	     xguest_r:xguest_t:s0
       system_r:local_login_t:s0     xguest_r:xguest_t:s0
       system_r:remote_login_t:s0    xguest_r:xguest_t:s0
       system_r:sshd_t:s0	     xguest_r:xguest_t:s0
       system_r:xdm_t:s0	     xguest_r:xguest_t:s0
       xguest_r:xguest_t:s0	     xguest_r:xguest_t:s0
