[PATCH bpf-next v2 0/6] bpf trampoline for arm64

by Xu Kuohai

Add bpf trampoline support for arm64. Most of the logic is the same as x86. Tested on qemu, result: #55 fentry_fexit:OK #56 fentry_test:OK #58 fexit_sleep:OK #59 fexit_stress:OK #60 fexit_test:OK #67 get_func_args_test:OK #68 get_func_ip_test:OK #101 modify_return:OK v2: - Add Song's ACK - Change the multi-line comment in is_valid_bpf_tramp_flags() into net style (patch 3) - Fix a deadloop issue in ftrace selftest (patch 2) - Replace pt_regs->x0 with pt_regs->orig_x0 in patch 1 commit message - Replace "bpf trampoline" with "custom trampoline" in patch 1, as ftrace direct call is not only used by bpf trampoline. v1: https://lore.kernel.org/bpf/20220413054959.1053668-1-xukuohai@huawei.com/ Xu Kuohai (6): arm64: ftrace: Add ftrace direct call support ftrace: Fix deadloop caused by direct call in ftrace selftest bpf: Move is_valid_bpf_tramp_flags() to the public trampoline code bpf, arm64: Impelment bpf_arch_text_poke() for arm64 bpf, arm64: bpf trampoline for arm64 selftests/bpf: Fix trivial typo in fentry_fexit.c arch/arm64/Kconfig | 2 + arch/arm64/include/asm/ftrace.h | 10 + arch/arm64/kernel/asm-offsets.c | 1 + arch/arm64/kernel/entry-ftrace.S | 28 +- arch/arm64/net/bpf_jit.h | 14 +- arch/arm64/net/bpf_jit_comp.c | 390 +++++++++++++++++- arch/x86/net/bpf_jit_comp.c | 20 - include/linux/bpf.h | 5 + kernel/bpf/bpf_struct_ops.c | 4 +- kernel/bpf/trampoline.c | 35 +- kernel/trace/trace_selftest.c | 4 +- .../selftests/bpf/prog_tests/fentry_fexit.c | 4 +- 12 files changed, 482 insertions(+), 35 deletions(-) -- 2.30.2

[PATCH v7 0/6] selftests/resctrl: Add resctrl_tests into kselftest set

by Shaopeng Tan

Hello, The aim of this series is to make resctrl_tests run by using kselftest framework. - I modify resctrl_test Makefile and kselftest Makefile, to enable build/run resctrl_tests by using kselftest framework. Of course, users can also build/run resctrl_tests without using framework as before. - I change the default limited time for resctrl_tests to 120 seconds, to ensure the resctrl_tests finish in limited time on different environments. - When resctrl file system is not supported by environment or resctrl_tests is not run as root, return skip code of kselftest framework. - If resctrl_tests does not finish in limited time, terminate it as same as executing ctrl+c that kills parent process and child process. Difference from v6: - Fixed the typos. https://lore.kernel.org/lkml/20220318075807.2921063-1-tan.shaopeng@jp.fujit… [PATCH v6] This patch series is based on 'next' branch of linux-kselftest.

[PATCH V3 0/4] selftests: Remove duplicate CPUID wrappers

by Reinette Chatre

Changes since V2: - V2: https://lore.kernel.org/lkml/cover.1647360971.git.reinette.chatre@intel.com/ - Rebased against v5.18-rc4, no functional changes. - Add text in cover letter and first patch to highlight that the __cpuid_count() macro provided is not a new implementation but copied from gcc. Changes since V1: - V1: https://lore.kernel.org/lkml/cover.1644000145.git.reinette.chatre@intel.com/ - Change solution to not use __cpuid_count() from compiler's cpuid.h but instead use a local define of __cpuid_count() provided in kselftest.h to ensure tests continue working in all supported environments. (Shuah) - Rewrite cover letter and changelogs to reflect new solution. A few tests that require running CPUID do so with a private implementation of a wrapper for CPUID. This duplication of the CPUID wrapper should be avoided. Both gcc and clang/LLVM provide wrappers for CPUID but the wrappers are not available in the minimal required version of gcc, v3.2, that the selftests need to be used in. __cpuid_count() was added to gcc in v4.4, which is ok for kernels after v4.19 when the gcc minimal required version was changed to v4.6. Copy gcc's __cpuid_count() to provide a local define of __cpuid_count() to kselftest.h to ensure that selftests can still work in environments with older stable kernels (v4.9 and v4.14 that have the minimal required version of gcc of v3.2). Update tests with private CPUID wrappers to use the new macro.

[PATCH 0/5] Firmware loader support for ZSTD-compressed files

by Takashi Iwai

Hi, this is a revised patch set for RFC I posted some time ago (*). Since the ZSTD usage became much more popular now, it makes sense to have the consistent (de)compression support in the kernel, also for the firmware files. This patch set adds the support for ZSTD- compressed firmware files as well as the extension of selftests, in addition to a couple of relevant fixes in selftests.

[PATCH] selftests/resctrl: Fix null pointer dereference on open failed

by Colin Ian King

Currently if opening /dev/null fails to open then file pointer fp is null and further access to fp via fprintf will cause a null pointer dereference. Fix this by returning a negative error value when a null fp is detected.
