V2 available at: https://lore.kernel.org/lkml/cover.1635447301.git.reinette.chatre@xxxxxxxxx/ Changes since V2: - Remove the non-kselftest placeholder patches while also removing their usage within the SGX selftests. Instead, the SGX selftests obtain needed data from CPUID directly (Dave). - Rewrite commit message of "selftests/x86/sgx: Fix a benign linker warning" (Dave). - Add Jarkko's signature to "selftests/sgx: Add page permission and exception test" (Jarkko). V1 available at: https://lore.kernel.org/lkml/cover.1631731214.git.reinette.chatre@xxxxxxxxx/ Changes since V1: - Biggest change: The non-kselftest placeholder patches included in this series that the kselftest work depends on are still being discussed elsewhere (link below) but has changed significantly since the first submission, warranting an update to the kselftest patches that depend on it. Jarkko: I made significant modifications to your "selftests/sgx: Add a new kselftest: unclobbered_vdso_oversubscribed" that you may want to look at. - Improve cover letter and changelogs (Dave). - Add Jarkko and Dave's signatures where obtained (Jarkko and Dave). - Fix Cedric's signature in patch 1 (Jarkko and Cedric). - Improve the loop locating the data segment (Jarkko). - Update placeholder patches that makes the amount of SGX memory available to latest version (v8). Previously this dependency consisted out of one patch, now it spans two. Hi Everybody, This series consists out of outstanding SGX selftests changes, rebased and gathered in a single series that can easily be merged for testing and development, and a few more changes added to expand the existing tests. The outstanding SGX selftest changes included in this series that have already been submitted separately are: * A more than two year old patch fixing a benign linker warning that is still present today: https://lore.kernel.org/linux-sgx/20191017030340.18301-2-sean.j.christopherson@xxxxxxxxx/ The original patch is added intact and not all email addresses within are valid. * Latest (v4) of Jarkko Sakkinen's series to add an oversubscription test: https://lore.kernel.org/linux-sgx/20210809093127.76264-1-jarkko@xxxxxxxxxx/ * Latest (v2) of Jarkko Sakkinen's patch that provides per-op parameter structs for the test enclave: https://lore.kernel.org/linux-sgx/20210812224645.90280-1-jarkko@xxxxxxxxxx/ The new changes introduced in this series builds on Jarkko's outstanding SGX selftest changes and adds new tests for page permissions, exception handling, and thread entry. Building and running enclaves is painful and traditionally requires a big software stack. This adds features like threads to the SGX selftests which are traditionally implemented in that big software stack. This helps test SGX kernel support with only code from the kernel tree.
