Writing to the /proc/self/attr files (encapsulated by the libselinux set*con functions) enables a program to request a specific security context for various operations instead of the policy-defined defaults. The security context specified using these calls is checked by an operation-specific permission, e.g. dyntransition for setcon, transition for setexeccon, create for setfscreatecon or setsockcreatecon, but the ability to request a context at all is controlled by a process permission. Omit these permissions from domain.te and only add them back where required so that only specific domains can even request a context other than the default defined by the policy.
