[PATCH AUTOSEL 5.11 23/38] kselftest/arm64: sve: Do not use non-canonical FFR register value

by Sasha Levin

From: Andre Przywara <andre.przywara(a)arm.com> [ Upstream commit 7011d72588d16a9e5f5d85acbc8b10019809599c ] The "First Fault Register" (FFR) is an SVE register that mimics a predicate register, but clears bits when a load or store fails to handle an element of a vector. The supposed usage scenario is to initialise this register (using SETFFR), then *read* it later on to learn about elements that failed to load or store. Explicit writes to this register using the WRFFR instruction are only supposed to *restore* values previously read from the register (for context-switching only). As the manual describes, this register holds only certain values, it: "... contains a monotonic predicate value, in which starting from bit 0 there are zero or more 1 bits, followed only by 0 bits in any remaining bit positions." Any other value is UNPREDICTABLE and is not supposed to be "restored" into the register. The SVE test currently tries to write a signature pattern into the register, which is *not* a canonical FFR value. Apparently the existing setups treat UNPREDICTABLE as "read-as-written", but a new implementation actually only stores canonical values. As a consequence, the sve-test fails immediately when comparing the FFR value: ----------- # ./sve-test Vector length: 128 bits PID: 207 Mismatch: PID=207, iteration=0, reg=48 Expected [cf00] Got [0f00] Aborted ----------- Fix this by only populating the FFR with proper canonical values. Effectively the requirement described above limits us to 17 unique values over 16 bits worth of FFR, so we condense our signature down to 4 bits (2 bits from the PID, 2 bits from the generation) and generate the canonical pattern from it. Any bits describing elements above the minimum 128 bit are set to 0. This aligns the FFR usage to the architecture and fixes the test on microarchitectures implementing FFR in a more restricted way.

[PATCH v7 1/4] lib: vsprintf: scanf: Negative number must have field width > 1

by Richard Fitzgerald

If a signed number field starts with a '-' the field width must be > 1, or unlimited, to allow at least one digit after the '-'. This patch adds a check for this. If a signed field starts with '-' and field_width == 1 the scanf will quit. It is ok for a signed number field to have a field width of 1 if it starts with a digit. In that case the single digit can be converted.

[RFC PATCH v5 00/10] KVM: selftests: some improvement and a new test for kvm page table

by Yanan Wang

Hi, This v5 series can mainly include two parts. Based on kvm queue branch: https://git.kernel.org/pub/scm/virt/kvm/kvm.git/log/?h=queue In the first part, all the known hugetlb backing src types specified with different hugepage sizes are listed, so that we can specify use of hugetlb source of the exact granularity that we want, instead of the system default ones. And as all the known hugetlb page sizes are listed, it's appropriate for all architectures. Besides, a helper that can get granularity of different backing src types(anonumous/thp/hugetlb) is added, so that we can use the accurate backing src granularity for kinds of alignment or guest memory accessing of vcpus. In the second part, a new test is added: This test is added to serve as a performance tester and a bug reproducer for kvm page table code (GPA->HPA mappings), it gives guidance for the people trying to make some improvement for kvm. And the following explains what we can exactly do through this test. The function guest_code() can cover the conditions where a single vcpu or multiple vcpus access guest pages within the same memory region, in three VM stages(before dirty logging, during dirty logging, after dirty logging). Besides, the backing src memory type(ANONYMOUS/THP/HUGETLB) of the tested memory region can be specified by users, which means normal page mappings or block mappings can be chosen by users to be created in the test. If ANONYMOUS memory is specified, kvm will create normal page mappings for the tested memory region before dirty logging, and update attributes of the page mappings from RO to RW during dirty logging. If THP/HUGETLB memory is specified, kvm will create block mappings for the tested memory region before dirty logging, and split the blcok mappings into normal page mappings during dirty logging, and coalesce the page mappings back into block mappings after dirty logging is stopped. So in summary, as a performance tester, this test can present the performance of kvm creating/updating normal page mappings, or the performance of kvm creating/splitting/recovering block mappings, through execution time. When we need to coalesce the page mappings back to block mappings after dirty logging is stopped, we have to firstly invalidate *all* the TLB entries for the page mappings right before installation of the block entry, because a TLB conflict abort error could occur if we can't invalidate the TLB entries fully. We have hit this TLB conflict twice on aarch64 software implementation and fixed it. As this test can imulate process from dirty logging enabled to dirty logging stopped of a VM with block mappings, so it can also reproduce this TLB conflict abort due to inadequate TLB invalidation when coalescing tables.

[PATCH] userfaultfd/shmem: fix MCOPY_ATOMIC_CONTNUE error handling + accounting

by Axel Rasmussen

Previously, in the error path, we unconditionally removed the page from the page cache. But in the continue case, we didn't add it - it was already there because the page is used by a second (non-UFFD-registered) mapping. So, in that case, it's incorrect to remove it as the other mapping may still use it normally. For this error handling failure, trivially exercise it in the userfaultfd selftest, to detect this kind of bug in the future. Also, we previously were unconditionally calling shmem_inode_acct_block. In the continue case, however, this is incorrect, because we would have already accounted for the RAM usage when the page was originally allocated (since at this point it's already in the page cache). So, doing it in the continue case causes us to double-count.

[PATCH v5] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

by Ilya Leoshkevich

Currently the following command produces an error message: linux# make kselftest TARGETS=bpf O=/mnt/linux-build # selftests: bpf: test_libbpf.sh # ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory # test_libbpf: failed at file test_l4lb.o # selftests: test_libbpf [FAILED] The error message might not affect the return code of make, therefore one needs to grep make output in order to detect it. This is not the only instance of the same underlying problem; any test with more than one element in $(TEST_PROGS) fails the same way. Another example: linux# make O=/mnt/linux-build TARGETS=splice kselftest [...] # ./short_splice_read.sh: 15: ./splice_read: not found # FAIL: /sys/module/test_module/sections/.init.text 2 not ok 2 selftests: splice: short_splice_read.sh # exit=1 The current logic prepends $(OUTPUT) only to the first member of $(TEST_PROGS). After that, run_one() does cd `dirname $TEST` For all tests except the first one, `dirname $TEST` is ., which means they cannot access the files generated in $(OUTPUT).
