[PATCH 00/14] selftests/sgx: Oversubscription, page permission, thread entry

by Reinette Chatre

Hi Everybody, This series consists out of outstanding SGX selftests changes, rebased and gathered in a single series that is more easily 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: * An almost 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 provide 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 original patch for this kernel dependency continues to be included in this series as a placeholder until the ongoing discussions are concluded. 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. Reinette Jarkko Sakkinen (9): x86/sgx: Add /sys/kernel/debug/x86/sgx_total_mem 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/x86/sgx.rst | 6 + arch/x86/kernel/cpu/sgx/main.c | 10 +- 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 | 341 +++++++++++++++--- 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 +- 10 files changed, 445 insertions(+), 87 deletions(-) -- 2.25.1

[PATCH v3 5/5] selftests/pfru: add test for Platform Firmware Runtime Update and Telemetry

by Chen Yu

Introduce a simple test for Platform Firmware Runtime Update and Telemetry drivers. It is based on ioctl to either update firmware driver or code injection, and read corresponding PFRU Telemetry log into user space. For example: ./pfru_test -h usage: pfru_test [OPTIONS] code injection: -l, --load -s, --stage -a, --activate -u, --update [stage and activate] -q, --query -d, --revid update telemetry: -G, --getloginfo -T, --type(0:execution, 1:history) -L, --level(0, 1, 2, 4) -R, --read -D, --revid log ./pfru_test -G log_level:4 log_type:0 log_revid:2 max_data_size:65536 chunk1_size:0 chunk2_size:1401 rollover_cnt:0 reset_cnt:4 ./pfru_test -q code injection image type:794bf8b2-6e7b-454e-885f-3fb9bb185402 fw_version:0 code_rt_version:1 driver update image type:0e5f0b14-f849-7945-ad81-bc7b6d2bb245 drv_rt_version:0 drv_svn:0 platform id:39214663-b1a8-4eaa-9024-f2bb53ea4723 oem id:a36db54f-ea2a-e14e-b7c4-b5780e51ba3d launch the update: ./pfru_test -l yours.cap -u -T 1 -L 4 Tested-by: Dou Shengnan <shengnanx.dou(a)intel.com> Signed-off-by: Chen Yu <yu.c.chen(a)intel.com> --- v3: No change since v2. v2: Do not allow non-root user to run this test. (Shuah Khan) Test runs on platform without pfru_telemetry should skip instead of reporting failure/error. (Shuah Khan) Reuse uapi/linux/pfru.h instead of copying it into the test directory.

[PATCH 5.13 018/380] selftests/ftrace: Fix requirement check of README file

by Greg Kroah-Hartman

From: Steven Rostedt (VMware) <rostedt(a)goodmis.org> commit 210f9df02611cbe641ced3239122b270fd907d86 upstream. The selftest for ftrace checks some features by checking if the README has text that states the feature is supported by that kernel. Unfortunately, this check gives false positives because it many not be checked if there's spaces in the string to check. This is due to the compare between the required variable with the ":README" string stripped, because neither has quotes around them.

[PATCH 00/24] Fix some issues at documentation

by Mauro Carvalho Chehab

Hi John, The first patch in this series fix a bad character used instead of a "(c)" UTF-8 symbol. The remaining ones fix several broken references to files under Documentation/, several due to DT schema conversions from .txt to .yaml.
