NAME         top

       user_contexts - The SELinux user contexts configuration files

DESCRIPTION         top

       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
       policy 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_contexts_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         top

       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.
