[PATCH v2 0/2] selftests/Make: Recursively build TARGETS list

by Dmitry Safonov

Version 2 changes: - fix `make install` in sub-directories with TARGETS, but with no TEST_LIST defined, i.e. selftests/net directory (reported-by: kernel test robot <yujie.liu(a)intel.com>) - vfork_exec selftest is about to be reverted, don't add .gitignore entry From [1]: > Please look into a wayto invoke all of them instead of adding individual > net/* to the main Makefile. This list seems to be growing. :) I might have misunderstood what was suggested... Here is an attempt to let sub-selftests define their own $(TARGETS) directories.

[PATCH net-next,v2 00/18] refactor duplicate codes in the qdisc class walk function

by Zhengchao Shao

The walk implementation of most qdisc class modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Last, thanks to Victor for his review. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -c cake ok 1 1212 - Create CAKE with default setting ok 2 3281 - Create CAKE with bandwidth limit ok 3 c940 - Create CAKE with autorate-ingress flag ok 4 2310 -

[PATCH v2 0/5] KVM: arm64: Enable ring-based dirty memory tracking

by Gavin Shan

This series enables the ring-based dirty memory tracking for ARM64. The feature has been available and enabled on x86 for a while. It is beneficial when the number of dirty pages is small in a checkpointing system or live migration scenario. More details can be found from fb04a1eddb1a ("KVM: X86: Implement ring-based dirty memory tracking"). The generic part has been comprehensive, meaning there isn't too much work, needed to extend it to ARM64. - PATCH[1] introduces KVM_REQ_RING_SOFT_FULL for x86 - PATCH[2] enables the feature on ARM64 - PATCH[3-5] improves kvm/selftests/dirty_log_test v1: https://lore.kernel.org/lkml/20220819005601.198436-1-gshan@redhat.com Testing ======= (1) kvm/selftests/dirty_log_test (2) Live migration by QEMU Changelog ========= v2: * Introduce KVM_REQ_RING_SOFT_FULL (Marc) * Changelog improvement (Marc) * Fix dirty_log_test without knowing host page size (Drew) Gavin Shan (5): KVM: x86: Introduce KVM_REQ_RING_SOFT_FULL KVM: arm64: Enable ring-based dirty memory tracking KVM: selftests: Use host page size to map ring buffer in dirty_log_test KVM: selftests: Clear dirty ring states between two modes in dirty_log_test KVM: selftests: Automate choosing dirty ring size in dirty_log_test Documentation/virt/kvm/api.rst | 2 +- arch/arm64/include/uapi/asm/kvm.h | 1 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/arm.c | 8 +++ arch/x86/kvm/x86.c | 5 +- include/linux/kvm_host.h | 1 + tools/testing/selftests/kvm/dirty_log_test.c | 53 ++++++++++++++------ tools/testing/selftests/kvm/lib/kvm_util.c | 2 +- virt/kvm/dirty_ring.c | 4 ++ 9 files changed, 59 insertions(+), 18 deletions(-) -- 2.23.0

[PATCH -v2] lib/notifier-error-inject: fix error when writing errno to debugfs file

by Akinobu Mita

The simple attribute files do not accept a negative value since the commit 488dac0c9237 ("libfs: fix error cast of negative value in simple_attr_write()"), so we can no longer use DEFINE_SIMPLE_ATTRIBUTE() to define a file operations for errno value.

[PATCH] lib/notifier-error-inject: fix error when writing errno to debugfs file

[PATCH net-next 00/18] refactor duplicate codes in the qdisc class walk function

by Zhengchao Shao

The walk implementation of most qdisc class modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -c cake ok 1 1212 - Create CAKE with default setting ok 2 3241 - Create CAKE with bandwidth limit ok 3 c940 - Create CAKE with autorate-ingress flag ok 4 2310 -

[PATCH 2/4] selftests/x86/mxcsr: Test the MXCSR state write via ptrace

by Chang S. Bae

The ptrace buffer is in the non-compacted format. The MXCSR state should be written to the target thread when either SSE or AVX component is enabled. Write an MXCSR value to the target and read back. Then it is validated with the XRSTOR/XSAVE result on the current. Signed-off-by: Chang S.

[PATCH v13 0/3] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in the commit log of Patch 1/3 or in Documentation/x86/tdx.rst (added by patch 3/3). Following are the details of the patch set: Patch 1/3 -> Adds TDREPORT support. Patch 2/3 -> Adds selftest support for TDREPORT feature. Patch 3/3 -> Add attestation related documentation. Commit log history is maintained in the individual patches.

[PATCH net-next,v3 0/9] refactor duplicate codes in the tc cls walk function

by Zhengchao Shao

The walk implementation of most tc cls modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Last, thanks to Jamal and Victor for their review. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -e 0811 ok 1 0811 - Add multiple basic filter with cmp ematch u8/link layer and default action and dump them ./tdc.py -e 5129 ok 1 5129 - List basic filters ./tdc.py -c bpf-filter ok 1 23c3 -

[PATCH net-next 0/5] mptcp: allow privileged operations from user ns & cleanup

by Matthieu Baerts

This series allows privileged Netlink operations from user namespaces. When a non-root user configures MPTCP endpoints, the memory allocation is now accounted to this user. See patches 4 and 5. Apart from that, there are some cleanup: - Patch 1 adds a macro to improve code readability - Patch 2 regroups similar checks all together - Patch 3 uses an explicit boolean instead of a counter to do one more check Geliang Tang (2): selftests: mptcp: move prefix tests of addr_nr_ns2 together mptcp: add do_check_data_fin to replace copied Matthieu Baerts (1): mptcp: add mptcp_for_each_subflow_safe helper Thomas Haller (2): mptcp: allow privileged operations from user namespaces mptcp: account memory allocation in mptcp_nl_cmd_add_addr() to user net/mptcp/pm_netlink.c | 22 +++++++++---------- net/mptcp/protocol.c | 13 ++++++----- net/mptcp/protocol.h | 2 ++ .../testing/selftests/net/mptcp/mptcp_join.sh | 10 ++++----- 4 files changed, 24 insertions(+), 23 deletions(-) base-commit: 03fdb11da92fde0bdc0b6e9c1c642b7414d49e8d -- 2.37.2

[PATCH net-next 0/9] refactor duplicate codes in the tc cls walk function

by Zhengchao Shao

The walk implementation of most tc cls modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -e 0811 ok 1 0811 - Add multiple basic filter with cmp ematch u8/link layer and default action and dump them ./tdc.py -e 5129 ok 1 5129 - List basic filters ./tdc.py -c filters bpf ok 13 23c3 -

[V1 PATCH 0/5] Execute hypercalls from guests according to cpu type

by Vishal Annapurve

This series is posted in context of the discussion at: https://lore.kernel.org/lkml/Ywa9T+jKUpaHLu%2Fl@google.com/ Major changes: 1) Move common startup logic to a single common main function in kvm_util.c 2) Introduce following APIs: kvm_arch_main: to perform arch specific common startup. kvm_post_vm_load: to update the guest memory state to convey common information to guests. 3) For x86, capture cpu type at startup and pass on the cpu type to guest after guest elf is loaded. 4) Execute hypercall instruction from within guest VMs according to the cpu type. This will help prevent an extra kvm exit during hypercall execution.

[PATCH] selftests/futex: fix build for clang

by Ricardo Cañuelo

Don't use the test-specific header files as source files to force a target dependency, as clang will complain if more than one source file is used for a compile command with a single '-o' flag. Use the proper Makefile variables instead as defined in tools/testing/selftests/lib.mk.

[PATCH net-next,v2 0/9] refactor duplicate codes in the tc cls walk function

by Zhengchao Shao

The walk implementation of most tc cls modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -e 0811 ok 1 0811 - Add multiple basic filter with cmp ematch u8/link layer and default action and dump them ./tdc.py -e 5129 ok 1 5129 - List basic filters ./tdc.py -c bpf-filter ok 1 23c3 -

[PATCH v6 1/2] x86/fpu: Allow PKRU to be (once again) written by ptrace.

by Kyle Huey

From: Kyle Huey <me(a)kylehuey.com> When management of the PKRU register was moved away from XSTATE, emulation of PKRU's existence in XSTATE was added for reading PKRU through ptrace, but not for writing PKRU through ptrace. This can be seen by running gdb and executing `p $pkru`, `set $pkru = 42`, and `p $pkru`. On affected kernels (5.14+) the write to the PKRU register (which gdb performs through ptrace) is ignored. There are three APIs that write PKRU: sigreturn, PTRACE_SETREGSET with NT_X86_XSTATE, and KVM_SET_XSAVE. sigreturn still uses XRSTOR to write to PKRU. KVM_SET_XSAVE has its own special handling to make PKRU writes take effect (in fpu_copy_uabi_to_guest_fpstate). Push that down into copy_uabi_to_xstate and have PTRACE_SETREGSET with NT_X86_XSTATE pass in a pointer to the appropriate PKRU slot. copy_sigframe_from_user_to_xstate depends on copy_uabi_to_xstate populating the PKRU field in the task's XSTATE so that __fpu_restore_sig can do a XRSTOR from it, so continue doing that. This also adds code to initialize the PKRU value to the hardware init value (namely 0) if the PKRU bit is not set in the XSTATE header provided to ptrace, to match XRSTOR.

[PATCH v3 7/7] KVM: selftests: Add test for AArch32 ID registers

by Oliver Upton

Add a test to assert that KVM handles the AArch64 views of the AArch32 ID registers as RAZ/WI (writable only from userspace). For registers that were already hidden or unallocated, expect RAZ + invariant behavior.

[RFC PATCH] Hugetlb: Migrating hugetlb tests from libhugetlbfs

by Tarun Sahu

Libhugetlbfs is not being maintained actively, and some distro is dropping support for it. There are some tests that are good for testing hugetlb functionality in kernel, which can be migrated to either kernel kselftests or LTP. I am submitting this patch to get comments from community on the following 1. The test framework in ltp is most suitable for the tests that are in libhugetlbfs/tests/ which follow similar test framework. And there is already a section for hugetlb specific tests in LTP. So it makes more sense and less effort to migrate the test to LTP. Though I recommend migrating these tests to LTP, I would like to discuss tests should be migrated to LTP or kselftests. 2. Libhugetlbfs tests has license GNU Lesser GPL 2.1 or later, while kernel and LTP has license GPL2 or later, so can the test be migrated to kernel/kselftests or LTP. The below patch is libhugetlbfs/tests/direct.c which has been migrated to ltp/testcases/kernel/mem/hugetlb/hugemmap/hugemmap07.c Signed-off-by: Tarun Sahu <tsahu(a)linux.ibm.com> --- runtest/hugetlb | 2 + testcases/kernel/mem/.gitignore | 1 + .../kernel/mem/hugetlb/hugemmap/hugemmap07.c | 106 ++++++++++++++++++ 3 files changed, 109 insertions(+) create mode 100644 testcases/kernel/mem/hugetlb/hugemmap/hugemmap07.c diff --git a/runtest/hugetlb b/runtest/hugetlb index f719217ab..ee02835d3 100644 --- a/runtest/hugetlb +++ b/runtest/hugetlb @@ -3,6 +3,8 @@ hugemmap02 hugemmap02 hugemmap04 hugemmap04 hugemmap05 hugemmap05 hugemmap06 hugemmap06 +hugemmap07 hugemmap07 + hugemmap05_1 hugemmap05 -m hugemmap05_2 hugemmap05 -s hugemmap05_3 hugemmap05 -s -m diff --git a/testcases/kernel/mem/.gitignore b/testcases/kernel/mem/.gitignore index ff2910533..df5256ec8 100644 --- a/testcases/kernel/mem/.gitignore +++ b/testcases/kernel/mem/.gitignore @@ -4,6 +4,7 @@ /hugetlb/hugemmap/hugemmap04 /hugetlb/hugemmap/hugemmap05 /hugetlb/hugemmap/hugemmap06 +/hugetlb/hugemmap/hugemmap07 /hugetlb/hugeshmat/hugeshmat01 /hugetlb/hugeshmat/hugeshmat02 /hugetlb/hugeshmat/hugeshmat03 diff --git a/testcases/kernel/mem/hugetlb/hugemmap/hugemmap07.c b/testcases/kernel/mem/hugetlb/hugemmap/hugemmap07.c new file mode 100644 index 000000000..798735ed0 --- /dev/null +++ b/testcases/kernel/mem/hugetlb/hugemmap/hugemmap07.c @@ -0,0 +1,106 @@ +/* + * License/Copyright Details + */ + +#define _GNU_SOURCE +#include <stdio.h> +#include <sys/mount.h> +#include <limits.h> +#include <sys/param.h> +#include <sys/types.h> + +#include "tst_test.h" + +#define P0 "ffffffff" +#define IOSZ 4096 +char buf[IOSZ] __attribute__((aligned(IOSZ))); +static int fildes = -1, nfildes = -1; +static char TEMPFILE[MAXPATHLEN]; +static char NTEMPFILE[MAXPATHLEN]; + +void test_directio(void) +{ + long hpage_size; + void *p; + int ret; + + hpage_size = SAFE_READ_MEMINFO("Hugepagesize:"); + + fildes = SAFE_OPEN(TEMPFILE, O_RDWR | O_CREAT, 0600); + nfildes = SAFE_OPEN(NTEMPFILE, O_CREAT|O_EXCL|O_RDWR|O_DIRECT, 0600); + + p = mmap(NULL, hpage_size, PROT_READ|PROT_WRITE, MAP_PRIVATE, fildes, 0); + if (p == MAP_FAILED) + tst_brk(TFAIL | TERRNO, "mmap() Failed on %s", TEMPFILE); + + memcpy(p, P0, 8); + + /* Direct write from huge page */ + ret = write(nfildes, p, IOSZ); + if (ret == -1) + tst_brk(TFAIL | TERRNO, "Direct-IO write from huge page"); + if (ret != IOSZ) + tst_brk(TFAIL, "Short direct-IO write from huge page"); + if (lseek(nfildes, 0, SEEK_SET) == -1) + tst_brk(TFAIL | TERRNO, "lseek"); + + /* Check for accuracy */ + ret = read(nfildes, buf, IOSZ); + if (ret == -1) + tst_brk(TFAIL | TERRNO, "Direct-IO read to normal memory"); + if (ret != IOSZ) + tst_brk(TFAIL, "Short direct-IO read to normal memory"); + if (memcmp(P0, buf, 8)) + tst_brk(TFAIL, "Memory mismatch after Direct-IO write"); + if (lseek(nfildes, 0, SEEK_SET) == -1) + tst_brk(TFAIL | TERRNO, "lseek"); + + /* Direct read to huge page */ + memset(p, 0, IOSZ); + ret = read(nfildes, p, IOSZ); + if (ret == -1) + tst_brk(TFAIL | TERRNO, "Direct-IO read to huge page"); + if (ret != IOSZ) + tst_brk(TFAIL, "Short direct-IO read to huge page"); + + /* Check for accuracy */ + if (memcmp(p, P0, 8)) + tst_brk(TFAIL, "Memory mismatch after Direct-IO read"); + tst_res(TPASS, "Successfully tested Hugepage Direct I/O"); +} + +void setup(void) +{ + if (tst_hugepages == 0) + tst_brk(TCONF, "Not enough hugepages for testing."); + + if (!Hopt) + Hopt = tst_get_tmpdir(); + SAFE_MOUNT("none", Hopt, "hugetlbfs", 0, NULL); + + snprintf(TEMPFILE, sizeof(TEMPFILE), "%s/mmapfile%d", Hopt, getpid()); + snprintf(NTEMPFILE, sizeof(NTEMPFILE), "%s/nmmapfile%d", "/home/", getpid()); +} + +void cleanup(void) +{ + close(fildes); + close(nfildes); + remove(TEMPFILE); + remove(NTEMPFILE); + umount2(Hopt, MNT_DETACH); +} + +static struct tst_test test = { + .needs_root = 1, + .needs_tmpdir = 1, + .options = (struct tst_option[]) { + {"H:", &Hopt, "Location of hugetlbfs, i.e. -H /var/hugetlbfs"}, + {"s:", &nr_opt, "Set the number of the been allocated hugepages"}, + {} + }, + .setup = setup, + .cleanup = cleanup, + .test_all = test_directio, + .hugepages = {2, TST_REQUEST}, +}; -- 2.31.1

[PATCH v12 0/3] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in the commit log of Patch 1/3 or in Documentation/x86/tdx.rst (added by patch 3/3). Following are the details of the patch set: Patch 1/3 -> Adds TDREPORT support. Patch 2/3 -> Adds selftest support for TDREPORT feature. Patch 3/3 -> Add attestation related documentation. Commit log history is maintained in the individual patches.
