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
 
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
