[RESEND PATCH v6] x86/fpu: Trying to fix writing PKRU through ptrace

by Kyle Huey

Hello Linus, I've been trying since July to get this regression that was introduced in 5.14 fixed. This is my third time submitting this version of the patch in the last two months. Both prior submissions have not received any comments from (nor have they been applied by) the x86 maintainers. I don't really know what else to do at this point beyond "complain to the management" as it were. I appreciate anything you can do to unjam things here. - Kyle

[PATCH v2 00/21] arm64/sme: Support SME 2 and SME 2.1

by Mark Brown

Arm have recently released versions 2 and 2.1 of the SME extension. Among the features introduced by SME 2 is some new architectural state, the ZT0 register. This series adds support for this and all the other features of the new SME versions. Since the architecture has been designed with the possibility of adding further ZTn registers in mind the interfaces added for ZT0 are done with this possibility in mind. As ZT0 is a simple fixed size register these interfaces are all fairly simple, the main complication is that ZT0 is only accessible when PSTATE.ZA is enabled. The memory allocation that we already do for PSTATE.ZA is extended to include space for ZT0. Due to textual collisions especially around the addition of hwcaps this is based on the concurrently sent series "arm64: Support for 2022 data processing instructions" but there is no meaningful interaction. v2: - Add missing initialisation of user->zt in signal context parsing. - Change the magic for ZT signal frames to 0x5a544e01 (ZTN0). Mark Brown (21): arm64/sme: Rename za_state to sme_state arm64: Document boot requirements for SME 2 arm64/sysreg: Update system registers for SME 2 and 2.1 arm64/sme: Document SME 2 and SME 2.1 ABI arm64/esr: Document ISS for ZT0 being disabled arm64/sme: Manually encode ZT0 load and store instructions arm64/sme: Enable host kernel to access ZT0 arm64/sme: Add basic enumeration for SME2 arm64/sme: Provide storage for ZT0 arm64/sme: Implement context switching for ZT0 arm64/sme: Implement signal handling for ZT arm64/sme: Implement ZT0 ptrace support arm64/sme: Add hwcaps for SME 2 and 2.1 features kselftest/arm64: Add a stress test program for ZT0 kselftest/arm64: Cover ZT in the FP stress test kselftest/arm64: Enumerate SME2 in the signal test utility code kselftest/arm64: Teach the generic signal context validation about ZT kselftest/arm64: Add test coverage for ZT register signal frames kselftest/arm64: Add SME2 coverage to syscall-abi kselftest/arm64: Add coverage of the ZT ptrace regset kselftest/arm64: Add coverage of SME 2 and 2.1 hwcaps Documentation/arm64/booting.rst | 10 + Documentation/arm64/elf_hwcaps.rst | 18 + Documentation/arm64/sme.rst | 52 ++- arch/arm64/include/asm/cpufeature.h | 6 + arch/arm64/include/asm/esr.h | 1 + arch/arm64/include/asm/fpsimd.h | 28 +- arch/arm64/include/asm/fpsimdmacros.h | 22 ++ arch/arm64/include/asm/hwcap.h | 6 + arch/arm64/include/asm/processor.h | 2 +- arch/arm64/include/uapi/asm/hwcap.h | 6 + arch/arm64/include/uapi/asm/sigcontext.h | 19 + arch/arm64/kernel/cpufeature.c | 27 ++ arch/arm64/kernel/cpuinfo.c | 6 + arch/arm64/kernel/entry-fpsimd.S | 30 +- arch/arm64/kernel/fpsimd.c | 53 ++- arch/arm64/kernel/hyp-stub.S | 6 + arch/arm64/kernel/idreg-override.c | 1 + arch/arm64/kernel/process.c | 21 +- arch/arm64/kernel/ptrace.c | 60 ++- arch/arm64/kernel/signal.c | 113 +++++- arch/arm64/tools/cpucaps | 1 + arch/arm64/tools/sysreg | 26 +- include/uapi/linux/elf.h | 1 + tools/testing/selftests/arm64/abi/hwcap.c | 115 ++++++ .../selftests/arm64/abi/syscall-abi-asm.S | 43 ++- .../testing/selftests/arm64/abi/syscall-abi.c | 40 +- tools/testing/selftests/arm64/fp/.gitignore | 2 + tools/testing/selftests/arm64/fp/Makefile | 5 + tools/testing/selftests/arm64/fp/fp-stress.c | 29 +- tools/testing/selftests/arm64/fp/sme-inst.h | 20 + tools/testing/selftests/arm64/fp/zt-ptrace.c | 365 ++++++++++++++++++ tools/testing/selftests/arm64/fp/zt-test.S | 324 ++++++++++++++++ .../testing/selftests/arm64/signal/.gitignore | 1 + .../selftests/arm64/signal/test_signals.h | 2 + .../arm64/signal/test_signals_utils.c | 3 + .../arm64/signal/testcases/testcases.c | 36 ++ .../arm64/signal/testcases/testcases.h | 1 + .../arm64/signal/testcases/zt_no_regs.c | 51 +++ .../arm64/signal/testcases/zt_regs.c | 85 ++++ 39 files changed, 1564 insertions(+), 73 deletions(-) create mode 100644 tools/testing/selftests/arm64/fp/zt-ptrace.c create mode 100644 tools/testing/selftests/arm64/fp/zt-test.S create mode 100644 tools/testing/selftests/arm64/signal/testcases/zt_no_regs.c create mode 100644 tools/testing/selftests/arm64/signal/testcases/zt_regs.c base-commit: ab0aff0601c29dc7b5cb2ecf42135dccbed6750a -- 2.30.2

[PATCH AUTOSEL 6.0 09/30] ksefltests: pidfd: Fix wait_states: Test terminated by timeout

by Sasha Levin

From: Li Zhijian <lizhijian(a)fujitsu.com> [ Upstream commit 88e1f16ba58665e9edfce437ea487da2fa759af9 ] 0Day/LKP observed that the kselftest blocks forever since one of the pidfd_wait doesn't terminate in 1 of 30 runs. After digging into the source, we found that it blocks at: ASSERT_EQ(sys_waitid(P_PIDFD, pidfd, &info, WCONTINUED, NULL), 0); wait_states has below testing flow: CHILD PARENT ---------------+-------------- 1 STOP itself 2 WAIT for CHILD STOPPED 3 SIGNAL CHILD to CONT 4 CONT 5 STOP itself 5' WAIT for CHILD CONT 6 WAIT for CHILD STOPPED The problem is that the kernel cannot ensure the order of 5 and 5', once 5 goes first, the test will fail. we can reproduce it by: $ while true; do make run_tests -C pidfd; done Introduce a blocking read in child process to make sure the parent can check its WCONTINUED.

[PATCH v2 1/2] selftests: proc: Fix proc-empty-vm build error on non x86_64

by Punit Agrawal

The proc-empty-vm test is implemented for x86_64 and fails to build for other architectures. Rather then emitting a compiler error it would be preferable to only build the test on supported architectures. Mark proc-empty-vm as a test for x86_64 and customise the Makefile to build it only when building for this target architecture.

[RFC PATCH 0/3] Use TAP in some more KVM selftests

by Thomas Huth

Many KVM selftests are completely silent. This has the disadvantage for the users that they do not know what's going on here. For example, some time ago, a tester asked me how to know whether a certain new sub-test has been added to one of the s390x test binaries or not (which he didn't compile on his own), which is hard to judge when there is no output. So I finally went ahead and implemented TAP output in the s390x-specific tests some months ago. Now I wonder whether that could be a good strategy for the x86 and generic tests, too? As a little RFC patch series, I've converted three more KVM selftests to use TAP output. If we decide that this is the right way to go, I can work on other tests later, too. Thomas Huth (3): KVM: selftests: Use TAP interface in the kvm_binary_stats_test KVM: selftests: x86: Use TAP interface in the sync_regs test KVM: selftests: x86: Use TAP interface in the tsc_msrs_test .../selftests/kvm/kvm_binary_stats_test.c | 11 +- .../selftests/kvm/x86_64/sync_regs_test.c | 113 ++++++++++++++---- .../selftests/kvm/x86_64/tsc_msrs_test.c | 16 ++- 3 files changed, 114 insertions(+), 26 deletions(-) -- 2.31.1

[PATCH v3 0/5] Some improvements of resctrl selftest

by Shaopeng Tan

Hello, The aim of this patch series is to improve the resctrl selftest. Without these fixes, some unnecessary processing will be executed and test results will be confusing. There is no behavior change in test themselves. [patch 1] Make write_schemata() run to set up shemata with 100% allocation on first run in MBM test. [patch 2] The MBA test result message is always output as "ok", make output message to be "not ok" if MBA check result is failed. [patch 3] When a child process is created by fork(), the buffer of the parent process is also copied. Flush the buffer before executing fork(). [patch 4] Add a signal handler to cleanup properly before exiting the parent process, if there is an error occurs after creating a child process with fork() in the CAT test. [patch 5] Before exiting each test CMT/CAT/MBM/MBA, clear test result files function cat/cmt/mbm/mba_test_cleanup() are called twice. Delete once. This patch series is based on Linux v6.1-rc3 Difference from v2: Moved [PATCH v2 3/4] to the last and insert patch 4 before it. [patch 1] Fixed the typo miss in the changelog and initialized *p(resctrl_val_param) before use it. And since there was no MBM processing in write_schemata(), added it. [patch 4] A signal handler is introduced in this patch. With this patch, patch 5 clear duplicate code cat/cmt/mbm/mba_test_cleanup() without falling into the indicated trap. https://lore.kernel.org/lkml/bdb19cf6-dd4b-2042-7cda-7f6108e543aa@intel.com/ Pervious versions of this series: [v1] https://lore.kernel.org/lkml/20220914015147.3071025-1-tan.shaopeng@jp.fujit… [v2] https://lore.kernel.org/lkml/20221005013933.1486054-1-tan.shaopeng@jp.fujit… Shaopeng Tan (5): selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test selftests/resctrl: Return MBA check result and make it to output message selftests/resctrl: Flush stdout file buffer before executing fork() selftests/resctrl: Cleanup properly when an error occurs in CAT test. selftests/resctrl: Remove duplicate codes that clear each test result file tools/testing/selftests/resctrl/cat_test.c | 29 +++++++++++++------ tools/testing/selftests/resctrl/mba_test.c | 8 ++--- tools/testing/selftests/resctrl/mbm_test.c | 13 +++++---- .../testing/selftests/resctrl/resctrl_tests.c | 4 --- tools/testing/selftests/resctrl/resctrl_val.c | 1 + tools/testing/selftests/resctrl/resctrlfs.c | 5 +++- 6 files changed, 36 insertions(+), 24 deletions(-) -- 2.27.0

[PATCH RESEND 0/7] KUnit documentation rewording

by Bagas Sanjaya

Hi everyone, sorry for quickly resending this patch series due to duplicated patch [7/7] sent as result of amending the corresponding commit. The proses written in KUnit documentation are IMO incomprehensible (my brain has to process what the meaning of words used) and different from wordings that I normally read from technical writings. Thus, rewrite these using clearer words. Anyway, it's great to see native English speakers help reviewing this series. The first two patches are v3 of rewriting "Writing Your First Test" section of "Getting Started" patch [1], which was submitted about a month ago. The rest are actual documentation rewriting. Note that this series only rewrites intro, test writing and running docs.
