selinux_file_context_cmp(3) Library Functions Manual selinux_file_context_cmp(3)NAME
selinux_file_context_cmp - Compare two SELinux security contexts excluding the 'user' component.
SYNOPSIS
#include <selinux/selinux.h>
int selinux_file_context_cmp(const security_context_t a,
const security_context_t b);
DESCRIPTION
selinux_file_context_cmp compares two context strings excluding the user component with strcmp(3) as shown in the EXAMPLE section.
This is useful as for most object contexts, the user component is not relevant.
RETURN VALUE
The return values follow the strcmp(3) function, where:
0 if they are equal.
1 if a is greater than b
-1 if a is less than b
ERRORS
None.
NOTES
The contexts being compared do not specifically need to be file contexts.
EXAMPLE
If context a is:
user_u:user_r:user_t:s0
and context b is:
root:user_r:user_t:s0
then the actual strings compared are:
:user_r:user_t:s0 and :user_r:user_t:s0
Therefore they will match and selinux_file_context_cmp will return zero.

default_type(5) SELinux configuration default_type(5)NAME
default_type - The SELinux default type configuration file.
DESCRIPTION
The default_type file contains entries that allow SELinux-aware applications such as newrole(1) to select a default type for a role if one
is not supplied.
selinux_default_type_path(3) will return the active policy path to this file. The default, default type file is:
/etc/selinux/{SELINUXTYPE}/contexts/default_type
Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).
get_default_type(3) reads this file to determine a type for the active policy.
FILE FORMAT
Each line within the default_type file is formatted with role:type entries where:
role
The SELinux role.
type
The domain type that is returned for this role.
EXAMPLE
# ./contexts/default_type
auditadm_r:auditadm_t
user_r:user_t
