I would prefer userspace tests to remain part of the selinux userspace repository, invoked upon make test there. A test policy if required should be possible via a separate standalone cil or te/fc policy module that doesn't depend on the testsuite policy. > > Signed-off-by: Richard Haines <richard_c_haines@btinternet.com> > --- > V2 Changes: > Allow option to run other restorecon binaries. > Only run if userspace tests enabled. > Add tests for "Ignore the stem..." patch > V3 Changes: > Add tests for No CAP_SYS_ADMIN permission and SKIP_DIGEST > > README.md | 7 + > policy/Makefile | 8 + > policy/test_restorecon.te | 74 ++++++++ > tests/Makefile | 7 + > tests/file/test | 2 +- > tests/restorecon/.gitignore | 5 + > tests/restorecon/Makefile | 7 + > tests/restorecon/check_fs.c | 69 ++++++++ > tests/restorecon/get_all_digests.c | 176 +++++++++++++++++++ > tests/restorecon/restorecon.c | 80 +++++++++ > tests/restorecon/restorecon_xattr.c | 116 +++++++++++++ > tests/restorecon/selinux_restorecon_skip.c | 66 ++++++++ > tests/restorecon/test | 188 +++++++++++++++++++++ > 13 files changed, 804 insertions(+), 1 deletion(-) > create mode 100644 policy/test_restorecon.te > create mode 100644 tests/restorecon/.gitignore > create mode 100644 tests/restorecon/Makefile > create mode 100644 tests/restorecon/check_fs.c > create mode 100644 tests/restorecon/get_all_digests.c > create mode 100644 tests/restorecon/restorecon.c > create mode 100644 tests/restorecon/restorecon_xattr.c > create mode 100644 tests/restorecon/selinux_restorecon_skip.c > create mode 100755 tests/restorecon/test > > diff --git a/README.md b/README.md > index 26784f8..329a495 100644 > --- a/README.md > +++ b/README.md > @@ -114,6 +114,13 @@ the tests: > > ## Running the Tests > > +The SELinux testsuite is primarily a set of regression tests for the SELinux > +kernel, however it is possible to include the testing of core userspace > +services such as library functions or utilities.

This will test the updated libselinux selinux_restorecon(3) using a simple test version of "restorecon", or if the test is run locally, a '-p' option can be used to supply the path of a full version of restorecon(8) (see note in restorecon/test). As the SELinux testsuite is primarily a set of regression tests for the SELinux kernel, this change also adds support to include the testing of core userspace services such as library functions or utilities. To install and run these type of tests, the following must be run first: # export TEST_USERSPACE=y Signed-off-by: Richard Haines <richard_c_haines@btinternet.com> --- V2 Changes: Allow option to run other restorecon binaries.
