[PATCH 3/6] selftests/sgx: Ignore OpenSSL 3.0 deprecated functions warning

by Jarkko Sakkinen

From: Kristen Carlson Accardi <kristen(a)linux.intel.com> OpenSSL 3.0 deprecates some of the functions used in the SGX selftests, causing build errors on new distros. For now ignore the warnings until support for the functions is no longer available and mark FIXME so that it can be clear this should be removed at some point.

[RFC V2 PATCH 0/8] selftests: KVM: SEV: selftests for fd-based private memory

by Vishal Annapurve

This series implements selftests executing SEV VMs to target the feature floated by Chao via: https://lore.kernel.org/linux-mm/20220706082016.2603916-12-chao.p.peng@linu… Below changes aim to test the fd based approach for guest private memory in context of SEV VMs executing on AMD SEV compatible platforms. sev_private_mem_test.c file adds selftest to access private memory from the guest via private/shared accesses and checking if the contents can be leaked to/accessed by vmm via shared memory view before/after conversions. To allow SEV/SEV-ES VMs to toggle the encryption bit during memory conversion, support is added for mapping guest pagetables to guest va ranges and passing the mapping information to guests via shared pages. This series has dependency on following patch series: 1) V7 series patches from Chao mentioned above. 2) https://lore.kernel.org/lkml/20220810152033.946942-1-pgonda@google.com/T/#u - Series posted by Peter containing patches from Michael and Sean 3) https://lore.kernel.org/lkml/Ywa9T+jKUpaHLu%2Fl@google.com/T/ - Series posted for similar selftests executing non-confidential VMs. Github link for the patches posted as part of this series: https://github.com/vishals4gh/linux/commits/sev_upm_selftests_rfcv2 Vishal Annapurve (8): selftests: kvm: x86_64: Add support for pagetable tracking kvm: Add HVA range operator arch: x86: sev: Populate private memory fd during LAUNCH_UPDATE_DATA selftests: kvm: sev: Support memslots with private memory selftests: kvm: Update usage of private mem lib for SEV VMs selftests: kvm: Support executing SEV VMs with private memory selftests: kvm: Refactor testing logic for private memory selftests: kvm: Add private memory test for SEV VMs arch/x86/kvm/svm/sev.c | 99 ++++++- include/linux/kvm_host.h | 8 + tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 2 + .../selftests/kvm/include/kvm_util_base.h | 105 +++++++ .../kvm/include/x86_64/private_mem.h | 10 +- .../include/x86_64/private_mem_test_helper.h | 13 + .../selftests/kvm/include/x86_64/sev.h | 2 + tools/testing/selftests/kvm/lib/kvm_util.c | 78 ++++- .../selftests/kvm/lib/x86_64/private_mem.c | 189 ++++++++++-- .../kvm/lib/x86_64/private_mem_test_helper.c | 273 ++++++++++++++++++ .../selftests/kvm/lib/x86_64/processor.c | 32 ++ tools/testing/selftests/kvm/lib/x86_64/sev.c | 15 +- .../selftests/kvm/x86_64/private_mem_test.c | 246 +--------------- .../kvm/x86_64/sev_private_mem_test.c | 21 ++ virt/kvm/kvm_main.c | 87 +++++- 16 files changed, 880 insertions(+), 301 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/x86_64/private_mem_test_helper.h create mode 100644 tools/testing/selftests/kvm/lib/x86_64/private_mem_test_helper.c create mode 100644 tools/testing/selftests/kvm/x86_64/sev_private_mem_test.c -- 2.37.2.672.g94769d06f0-goog

[PATCH v3 0/2] begin KTAP spec v2 process

by frowand.list＠gmail.com

From: Frank Rowand <frank.rowand(a)sony.com> The process to create version 2 of the KTAP Specification is documented in email discussions. I am attempting to capture this information at https://elinux.org/Test_Results_Format_Notes#KTAP_version_2 I am already not following the suggested process, which says: "...please try to follow this principal of one major topic per email thread." I think that is ok in this case because the two patches are related and (hopefully) not controversial. Changes since patch version 2: - correct version 1 change text - version 1 patch 2/2 had not yet been applied when I created version 2, refresh version 2 patch 2/2 for new context Changes since patch version 1: - drop patch 2/2. Jonathan Corbet has already applied this patch into version 1 of the Specification - add new patch 2/2 Frank Rowand (2): ktap_v2: change version to 2-rc in KTAP specification ktap_v2: change "version 1" to "version 2" in examples Documentation/dev-tools/ktap.rst | 25 +++++++++++++------------ 1 file changed, 13 insertions(+), 12 deletions(-) -- Frank Rowand <frank.rowand(a)sony.com>

[PATCH bpf-next v7 00/24] Introduce eBPF support for HID devices

by Benjamin Tissoires

Hi, here comes the v7 of the HID-BPF series. Again, for a full explanation of HID-BPF, please refer to the last patch in this series (24/24). This version sees some minor improvements compared to v6, only focusing on the reviews I got. I also wanted to mention that I have started working on the userspace side to "see" how the BPF programs would look when automatically loaded. See the udev-hid-bpf project[0] for the code. The idea is to define the HID-BPF userspace programs so we can reuse the same semantic in the kernel. I am quite happy with the results: this looks pretty similar to a kernel module in term of design. The .bpf.c file is a standalone compilation unit, and instead of having a table of ids, the filename is used (based on the modalias). This allows to have a "probe" like function that we can run to decide if the program needs to be attached or not. All in all, the end result is that we can write the bpf program, compile it locally, and send the result to the user. The user needs to drop the .bpf.o in a local folder, and udev-hid-bpf will pick it up the next time the device is plugged in. No other operations is required. Next step will be to drop the same source file in the kernel source tree, and have some magic to automatically load the compiled program when the device is loaded.

[PATCH v2] kunit: fix assert_type for comparison macros

by Sander Vanheule

When replacing KUNIT_BINARY_*_MSG_ASSERTION() macros with KUNIT_BINARY_INT_ASSERTION(), the assert_type parameter was not always correctly transferred. Specifically, the following errors were introduced: - KUNIT_EXPECT_LE_MSG() uses KUNIT_ASSERTION - KUNIT_ASSERT_LT_MSG() uses KUNIT_EXPECTATION - KUNIT_ASSERT_GT_MSG() uses KUNIT_EXPECTATION A failing KUNIT_EXPECT_LE_MSG() test thus prevents further tests from running, while failing KUNIT_ASSERT_{LT,GT}_MSG() tests do not prevent further tests from running. This is contrary to the documentation, which states that failing KUNIT_EXPECT_* macros allow further tests to run, while failing KUNIT_ASSERT_* macros should prevent this. Revert the KUNIT_{ASSERTION,EXPECTATION} switches to fix the behaviour for the affected macros.
