Joe Conway	794e2558be	Fix sepgsql regression tests. The regression tests for sepgsql were broken by changes in the base distro as-shipped policies. Specifically, definition of unconfined_t in the system default policy was changed to bypass multi-category rules, which the regression test depended on. Fix that by defining a custom privileged domain (sepgsql_regtest_superuser_t) and using it instead of system's unconfined_t domain. The new sepgsql_regtest_superuser_t domain performs almost like the current unconfined_t, but restricted by multi-category policy as the traditional unconfined_t was. The custom policy module is a self defined domain, and so should not be affected by related future system policy changes. However, it still uses the unconfined_u:unconfined_r pair for selinux-user and role. Those definitions have not been changed for several years and seem less risky to rely on than the unconfined_t domain. Additionally, if we define custom user/role, they would need to be manually defined at the operating system level, adding more complexity to an already non-standard and complex regression test. Back-patch to 9.3. The regression tests will need more work before working correctly on 9.2. Starting with 9.2, sepgsql has had dependencies on libselinux versions that are only available on newer distros with the changed set of policies (e.g. RHEL 7.x). On 9.1 sepgsql works fine with the older distros with original policy set (e.g. RHEL 6.x), and on which the existing regression tests work fine. We might want eventually change 9.1 sepgsql regression tests to be more independent from the underlying OS policies, however more work will be needed to make that happen and it is not clear that it is worth the effort.

Robert Haas	0f05840bf4	Allow sepgsql labels to depend on object name. The main change here is to call security_compute_create_name_raw() rather than security_compute_create_raw(). This ups the minimum requirement for libselinux from 2.0.99 to 2.1.10, but it looks like most distributions will have picked that up before 9.3 is out. KaiGai Kohei	13 years ago
Robert Haas	523176cbf1	sepgsql_setcon(). This is intended as infrastructure to allow sepgsql to cooperate with connection pooling software, by allowing the effective security label to be set for each new connection. KaiGai Kohei, reviewed by Yeb Havinga.	14 years ago

Robert Haas	968bc6fac9	sepgsql, an SE-Linux integration for PostgreSQL This is still pretty rough - among other things, the documentation needs work, and the messages need a visit from the style police - but this gets the basic framework in place. KaiGai Kohei	15 years ago
