Add support for using negated or complemented self in the target type of
neverallow rules.
Some Refpolicy examples:
neverallow * ~self:{ capability cap_userns capability2 cap2_userns } *;
neverallow domain { domain -self -dockerc_t }:dir create;
# no violations
neverallow domain { domain -dockerc_t }:file ~{ append read_file_perms write };
libsepol.report_failure: neverallow on line 584 of policy/modules/kernel/kernel.te (or line 31357 of policy.conf) violated by allow sysadm_t httpd_bugzilla_script_t:file { create setattr relabelfrom relabelto unlink link rename };
libsepol.report_failure: neverallow on line 584 of policy/modules/kernel/kernel.te (or line 31357 of policy.conf) violated by allow spc_t spc_t:file { create };
libsepol.report_failure: neverallow on line 584 of policy/modules/kernel/kernel.te (or line 31357 of policy.conf) violated by allow container_t container_t:file { create };
libsepol.report_failure: neverallow on line 584 of policy/modules/kernel/kernel.te (or line 31357 of policy.conf) violated by allow chromium_t chromium_t:file { create };
libsepol.report_failure: neverallow on line 584 of policy/modules/kernel/kernel.te (or line 31357 of policy.conf) violated by allow spc_user_t spc_user_t:file { create };
libsepol.report_failure: neverallow on line 582 of policy/modules/kernel/kernel.te (or line 31355 of policy.conf) violated by allow sysadm_t httpd_bugzilla_script_t:dir { create };
neverallow domain { domain -self -dockerc_t }:file ~{ append read_file_perms write };
libsepol.report_failure: neverallow on line 583 of policy/modules/kernel/kernel.te (or line 31356 of policy.conf) violated by allow sysadm_t httpd_bugzilla_script_t:file { create setattr relabelfrom relabelto unlink link rename };
libsepol.report_failure: neverallow on line 582 of policy/modules/kernel/kernel.te (or line 31355 of policy.conf) violated by allow sysadm_t httpd_bugzilla_script_t:dir { create };
Using negated self in a complement, `~{ domain -self }`, is not
supported.
