dd a series of regression tests to validate that privilege requirements are implemented properly for a number of kernel subsystems. In general, they try to exercise the privilege first as the root user, then as a test user, in order to determine when privilege is being checked. Currently, these tests do not compare inside/outside jail, and probably should be enhanced to do that. Sponsored by: nCircle Network Security, Inc. Obtained from: TrustedBSD Project

Enhance and expand kernel privilege regression tests in support of work present in FreeBSD 7.0 to refine the kernel privilege model: - Introduce support for jail as a testing variable, in order to confirm that privileges are properly restricted in the jail environment. - Restructure overall testing approach so that privilege and jail conditions are set in the testing infrastructure before tests are invoked, and done so in a custom-created process to isolate the impact of tests from each other in a more consistent way. - Tests now provide setup and cleanup hooks that occur before and after the test runs. - New privilege tests are now present for several audit privileges, several credential management privileges, dmesg buffer reading privilege, and netinet raw socket creation. - Other existing tests are restructured and generally improved as a result of better framework structure and jail as a variable. For exampe, we now test that certain sysctls are writable only outside jail, while others are writable within jail. On a similar note, privileges relating to setting UFS file flags are now better exercised, as with the right to chmod and utimes files. Approved by: re (bmah) Obtained from: TrustedBSD Project
