[PATCH v5 00/13] RISCV: Add KVM_GET_REG_LIST API

by Haibo Xu

KVM_GET_REG_LIST will dump all register IDs that are available to KVM_GET/SET_ONE_REG and It's very useful to identify some platform regression issue during VM migration. Patch 1-7 re-structured the get-reg-list test in aarch64 to make some of the code as common test framework that can be shared by riscv. Patch 8 move reject_set check logic to a function so as to check for different errno for different registers. Patch 9 move finalize_vcpu back to run_test so that riscv can implement its specific operation. Patch 10 change to do the get/set operation only on present-blessed list. Patch 11 add the skip_set facilities so that riscv can skip set operation on some registers. Patch 12 enabled the KVM_GET_REG_LIST API in riscv. patch 13 added the corresponding kselftest for checking possible register regressions. The get-reg-list kvm selftest was ported from aarch64 and tested with Linux v6.4 on a Qemu riscv64 virt machine. --- Changed since v4: * Rebase to v6.4 * Address Andrew's suggestions and comments: Added skip_set concept Updated errno check logic Modified finalize_vcpu as weak function Andrew Jones (7): KVM: arm64: selftests: Replace str_with_index with strdup_printf KVM: arm64: selftests: Drop SVE cap check in print_reg KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config KVM: arm64: selftests: Rename vcpu_config and add to kvm_util.h KVM: arm64: selftests: Delete core_reg_fixup KVM: arm64: selftests: Split get-reg-list test code KVM: arm64: selftests: Finish generalizing get-reg-list Haibo Xu (6): KVM: arm64: selftests: Move reject_set check logic to a function KVM: arm64: selftests: Move finalize_vcpu back to run_test KVM: selftests: Only do get/set tests on present blessed list KVM: selftests: Add skip_set facility to get_reg_list test KVM: riscv: Add KVM_GET_REG_LIST API support KVM: riscv: selftests: Add get-reg-list test Documentation/virt/kvm/api.rst | 2 +- arch/riscv/kvm/vcpu.c | 375 +++++++++ tools/testing/selftests/kvm/Makefile | 11 +- .../selftests/kvm/aarch64/get-reg-list.c | 544 ++---------- tools/testing/selftests/kvm/get-reg-list.c | 395 +++++++++ .../selftests/kvm/include/kvm_util_base.h | 21 + .../selftests/kvm/include/riscv/processor.h | 3 + .../testing/selftests/kvm/include/test_util.h | 2 + tools/testing/selftests/kvm/lib/test_util.c | 15 + .../selftests/kvm/riscv/get-reg-list.c | 780 ++++++++++++++++++ 10 files changed, 1655 insertions(+), 493 deletions(-) create mode 100644 tools/testing/selftests/kvm/get-reg-list.c create mode 100644 tools/testing/selftests/kvm/riscv/get-reg-list.c -- 2.34.1

[PATCH] kunit: tool: undo type subscripts for subprocess.Popen

by Daniel Latypov

Writing `subprocess.Popen[str]` requires python 3.9+. kunit.py has an assertion that the python version is 3.7+, so we should try to stay backwards compatible. This conflicts a bit with commit 1da2e6220e11 ("kunit: tool: fix pre-existing `mypy --strict` errors and update run_checks.py"), since mypy complains like so > kunit_kernel.py:95: error: Missing type parameters for generic type "Popen" [type-arg] Note: `mypy --strict --python-version 3.7` does not work. We could annotate each file with comments like `# mypy: disable-error-code="type-arg" but then we might still get nudged to break back-compat in other files. This patch adds a `mypy.ini` file since it seems like the only way to disable specific error codes for all our files. Note: run_checks.py doesn't need to specify `--config_file mypy.ini`, but I think being explicit is better, particularly since most kernel devs won't be familiar with how mypy works.

[PATCH v3 00/10] tracing: introducing eventfs

by Ajay Kaher

Events Tracing infrastructure contains lot of files, directories (internally in terms of inodes, dentries). And ends up by consuming memory in MBs. We can have multiple events of Events Tracing, which further requires more memory. Instead of creating inodes/dentries, eventfs could keep meta-data and skip the creation of inodes/dentries. As and when require, eventfs will create the inodes/dentries only for required files/directories. Also eventfs would delete the inodes/dentries once no more requires but preserve the meta data. Tracing events took ~9MB, with this approach it took ~4.5MB for ~10K files/dir. v2: Patch 01: new patch:'Require all trace events to have a TRACE_SYSTEM' Patch 02: moved from v1 1/9 Patch 03: moved from v1 2/9 As suggested by Zheng Yejian, introduced eventfs_prepare_ef() helper function to add files or directories to eventfs fix WARNING reported by kernel test robot in v1 8/9 Patch 04: moved from v1 3/9 used eventfs_prepare_ef() to add files fix WARNING reported by kernel test robot in v1 8/9 Patch 05: moved from v1 4/9 fix compiling warning reported by kernel test robot in v1 4/9 Patch 06: moved from v1 5/9 Patch 07: moved from v1 6/9 Patch 08: moved from v1 7/9 Patch 09: moved from v1 8/9 rebased because of v3 01/10 Patch 10: moved from v1 9/9 v1: Patch 1: add header file Patch 2: resolved kernel test robot issues protecting eventfs lists using nested eventfs_rwsem Patch 3: protecting eventfs lists using nested eventfs_rwsem Patch 4: improve events cleanup code to fix crashes Patch 5: resolved kernel test robot issues removed d_instantiate_anon() calls Patch 6: resolved kernel test robot issues fix kprobe test in eventfs_root_lookup() protecting eventfs lists using nested eventfs_rwsem Patch 7: remove header file Patch 8: pass eventfs_rwsem as argument to eventfs functions called eventfs_remove_events_dir() instead of tracefs_remove() from event_trace_del_tracer() Patch 9: new patch to fix kprobe test case fs/tracefs/Makefile | 1 + fs/tracefs/event_inode.c | 757 ++++++++++++++++++ fs/tracefs/inode.c | 124 ++- fs/tracefs/internal.h | 25 + include/linux/trace_events.h | 1 + include/linux/tracefs.h | 49 ++ kernel/trace/trace.h | 3 +- kernel/trace/trace_events.c | 78 +- .../ftrace/test.d/kprobe/kprobe_args_char.tc | 4 +- .../test.d/kprobe/kprobe_args_string.tc | 4 +- 10 files changed, 994 insertions(+), 52 deletions(-) create mode 100644 fs/tracefs/event_inode.c create mode 100644 fs/tracefs/internal.h -- 2.40.0

[PATCH v2 0/3] selftests/nolibc: improve test report support

by Zhangjin Wu

Hi, Willy Here is the v2 of our old patchset about test report [1]. The trailing '\r' fixup has been merged, so, here only resend the left parts with an additional patch to restore the failed tests print. This patchset is rebased on the dev.2023.06.14a branch of linux-rcu [2]. Tests have passed for 'x86 run': 138 test(s) passed, 0 skipped, 0 failed. See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/run.out Also did 'run-user' for x86, mips and arm64. Changes from v1 -> v2: 1. selftests/nolibc: add a standalone test report macro As Willy pointed out, the old method with additional test-report target not work in 'make -j'. A new macro is added to share the same report logic among the run-user, run and rerun targets, the path to test log file is 2. selftests/nolibc: always print the path to test log file Always print the path to test log file, but move it to a new line to avoid annoying people when the test pass without any failures. 3. selftests/nolibc: restore the failed tests print Restore printing of the failed tests to avoid manually opening the test log file when there are really failues.

[PATCH v5 0/5] nolibc: add part2 of support for rv32

by Zhangjin Wu

Hi, Willy This is the revision of the v4 part2 of support for rv32 [1], this further split the generic KARCH code out of the old rv32 compile patch and also add kernel specific KARCH and nolibc specific NARCH for tools/include/nolibc/Makefile too. This is rebased on the dev.2023.06.14a branch of linux-rcu repo [2] with basic run-user and run tests. Changes from v4 -> v5: * selftests/nolibc: allow customize kernel specific ARCH variable The KARCH customize support part splitted out of the old rv32 compile patch and removed the one passed to tools/include/nolibc/Makefile. * tools/nolibc: add kernel and nolibc specific ARCH variables Pass original ARCH to tools/include/nolibc/Makefile, add KARCH and NARCH for kernel and nolibc respectively. * selftests/nolibc: riscv: customize makefile for rv32 Now, it is rv32 specific, no generic code.

[PATCH v1 00/11] tools/nolibc: shrink arch support

by Zhangjin Wu

Hi, This patchset further improves porting of nolibc to new architectures, it is based on our previous v5 sysret helper series [1]. It mainly shrinks the assembly _start by moving most of its operations to a C version of _start_c() function. and also, it removes the old sys_stat() support by using the sys_statx() instead and therefore, removes all of the arch specific sys_stat_struct. Tested 'run' on all of the supported architectures: arch/board | result ------------|------------ arm/vexpress-a9 | 141 test(s) passed, 1 skipped, 0 failed. See all results in /labs/linux-lab/logging/nolibc/arm-vexpress-a9-nolibc-test.log arm/virt | 141 test(s) passed, 1 skipped, 0 failed.

Changes: * tools/nolibc: remove old arch specific stat support Just like the __NR_statx we used in nolibc-test.c, Let's only reserve sys_statx() and use it to implement the stat() function. Remove the old sys_stat() and sys_stat_struct completely. * tools/nolibc: add new crt.h with _start_c A new C version of _start_c() is added to only require a 'sp' argument and find the others (argc, argv, envp/environ, auxv) for us in C. * tools/nolibc: include crt.h before arch.h Include crt.h before arch.h to let _start() be able to call the new added _start_c() in arch-<ARCH>.h. * tools/nolibc: arm: shrink _start with _start_c tools/nolibc: aarch64: shrink _start with _start_c tools/nolibc: i386: shrink _start with _start_c tools/nolibc: x86_64: shrink _start with _start_c tools/nolibc: mips: shrink _start with _start_c tools/nolibc: loongarch: shrink _start with _start_c tools/nolibc: riscv: shrink _start with _start_c tools/nolibc: s390: shrink _start with _start_c Move most of the operations from the assembly _start() to the C _start_c(), only require to do minimal operations in assembly _start now. With this patchset, porting nolibc to a new architecture become easier, the powerpc porting will be added later.

[PATCH v4 00/10] tools/nolibc: add a new syscall helper

by Zhangjin Wu

Hi, Thomas, David, Willy Thanks very much for your kindly review. This is the revision of v3 "tools/nolibc: add a new syscall helper" [1], this mainly applies the suggestion from David in this reply [2] and rebased everything on the dev.2023.06.14a branch of linux-rcu [3]. The old __sysret() doesn't support the syscalls with pointer return value, this revision now supports such syscalls. The left mmap() syscall is converted to use this new __sysret() with additional test cases. Changes from v3 -> v4: * tools/nolibc: sys.h: add a syscall return helper tools/nolibc: unistd.h: apply __sysret() helper tools/nolibc: sys.h: apply __sysret() helper The original v3 series, no code change, except the Reviewed-by lines from Thomas. * tools/nolibc: unistd.h: reorder the syscall macros reorder the syscall macros in using order and align most of them. * tools/nolibc: add missing my_syscall6() for mips required by mmap() syscall, this is the last missing my_syscall6(). * tools/nolibc: __sysret: support syscalls who return a pointer Apply suggestion from David. Let __sysret() also supports syscalls with pointer return value, so, the return value is converted to unsigned long and the comparing of < 0 is converted to the comparing of [(unsigned long)-MAX_ERRNO, (unsigned long)-1]. This also allows return a huge value (not pointer) with highest bit as 1. It is able to merge this one to the first one if necessary. * tools/nolibc: clean up mmap() support Apply new __sysret(), clean up #ifdef and some macros. * selftests/nolibc: add EXPECT_PTREQ, EXPECT_PTRNE and EXPECT_PTRER selftests/nolibc: add sbrk_0 to test current brk getting selftests/nolibc: add mmap and munmap test cases Add some mmap & munmap test cases and the corresponding helpers, to verify one of the new helpers, a sbrk_0 test case is also added.

[PATCH] selftests/net: Add xt_policy config for xfrm_policy test

by Daniel Díaz

When running Kselftests with the current selftests/net/config the following problem can be seen with the net:xfrm_policy.sh selftest: # selftests: net: xfrm_policy.sh [ 41.076721] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 41.094787] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready [ 41.107635] IPv6: ADDRCONF(NETDEV_CHANGE): veth0: link becomes ready # modprobe: FATAL: Module ip_tables not found in directory /lib/modules/6.1.36 # iptables v1.8.7 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) # Perhaps iptables or your kernel needs to be upgraded. # modprobe: FATAL: Module ip_tables not found in directory /lib/modules/6.1.36 # iptables v1.8.7 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) # Perhaps iptables or your kernel needs to be upgraded. # SKIP: Could not insert iptables rule ok 1 selftests: net: xfrm_policy.sh # SKIP This is because IPsec "policy" match support is not available to the kernel. This patch adds CONFIG_NETFILTER_XT_MATCH_POLICY as a module to the selftests/net/config file, so that `make kselftest-merge` can take this into consideration.
