[PATCHv2 net 0/5] kselftests/net: add missed tests to Makefile

by Hangbin Liu

When generating the selftest to another folder, some tests are missing as they are not added in Makefile. e.g. make -C tools/testing/selftests/ install \ TARGETS="net" INSTALL_PATH=/tmp/kselftests These pathset add them separately to make the Fixes tags less. It would also make the stable tree or downstream backport easier. If you think there is no need to add the Fixes tag for this minor issue. I can repost a new patch and merge all the fixes together. Thanks v2: move toeplitz.sh/toeplitz_client.sh under TEST_PROGS_EXTENDED.

[PATCH 0/4] tracing/histogram: Division optimization and expression kselftests

by Kalesh Singh

This series adds optimiztion for division by constants and updates the histogram trigger expression kselftests and documentation. It is dependent on the series at [1] and the fix at [2]; and can be applied on top of those after dropping the patch 7 in [1].

[PATCH V2 00/15] selftests/sgx: Oversubscription, page permission, thread entry

by Reinette Chatre

V1 available at: https://lore.kernel.org/lkml/cover.1631731214.git.reinette.chatre@intel.com/ 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.christopher… 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@kernel.org/ * 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@kernel.org/ The reason why most of these patches are outstanding is that they depend on a kernel change that is still under discussion. Decision to wait in: https://lore.kernel.org/linux-sgx/f8674dac5579a8a424de1565f7ffa2b5bf2f8e36.… The latest patches (v8) for this dependency is included in this series as a placeholder until the ongoing discussions are concluded: https://lore.kernel.org/lkml/20211018135744.45527-1-jarkko@kernel.org/ https://lore.kernel.org/lkml/20211018135744.45527-2-jarkko@kernel.org/ 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. Reinette Jarkko Sakkinen (10): x86/sgx: Rename fallback labels in sgx_init() x86/sgx: Add an attribute for the amount of SGX memory in a NUMA node selftests/sgx: Assign source for each segment selftests/sgx: Make data measurement for an enclave segment optional selftests/sgx: Create a heap for the test enclave selftests/sgx: Dump segments and /proc/self/maps only on failure selftests/sgx: Encpsulate the test enclave creation selftests/sgx: Move setup_test_encl() to each TEST_F() selftests/sgx: Add a new kselftest: unclobbered_vdso_oversubscribed selftests/sgx: Provide per-op parameter structs for the test enclave Reinette Chatre (4): selftests/sgx: Rename test properties in preparation for more enclave tests selftests/sgx: Add page permission and exception test selftests/sgx: Enable multiple thread support selftests/sgx: Add test for multiple TCS entry Sean Christopherson (1): selftests/x86/sgx: Fix a benign linker warning Documentation/ABI/stable/sysfs-devices-node | 7 + arch/x86/kernel/cpu/sgx/main.c | 97 ++++- arch/x86/kernel/cpu/sgx/sgx.h | 2 + tools/testing/selftests/sgx/Makefile | 2 +- tools/testing/selftests/sgx/defines.h | 33 +- tools/testing/selftests/sgx/load.c | 40 +- tools/testing/selftests/sgx/main.c | 396 ++++++++++++++++-- tools/testing/selftests/sgx/main.h | 7 +- tools/testing/selftests/sgx/sigstruct.c | 12 +- tools/testing/selftests/sgx/test_encl.c | 60 ++- .../selftests/sgx/test_encl_bootstrap.S | 21 +- 11 files changed, 585 insertions(+), 92 deletions(-) base-commit: 7d2a07b769330c34b4deabeed939325c77a7ec2f -- 2.25.1
