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 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

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
