2021-08-02selftests/net: remove min gso test in packet_sndDust Li1-3/+0
This patch removed the 'raw gso min size - 1' test which always fails now: ./in_netns.sh ./psock_snd -v -c -g -l "${mss}" raw gso min size - 1 (expected to fail) tx: 1524 rx: 1472 OK After commit 7c6d2ecbda83 ("net: be more gentle about silly gso requests coming from user"), we relaxed the min gso_size check in virtio_net_hdr_to_skb(). So when a packet which is smaller then the gso_size, GSO for this packet will not be set, the packet will be send/recv successfully.

2021-07-30selftests/sgx: Fix Q1 and Q2 calculation in sigstruct.cTianjia Zhang1-20/+21
Q1 and Q2 are numbers with *maximum* length of 384 bytes. If the calculated length of Q1 and Q2 is less than 384 bytes, things will go wrong. E.g. if Q2 is 383 bytes, then 1. The bytes of q2 are copied to sigstruct->q2 in calc_q1q2(). 2. The entire sigstruct->q2 is reversed, which results it being 256 * Q2, given that the last byte of sigstruct->q2 is added to before the bytes given by calc_q1q2(). Either change in key or measurement can trigger the bug. E.g. an unmeasured heap could cause a devastating change in Q1 or Q2. Reverse exactly the bytes of Q1 and Q2 in calc_q1q2() before returning to the caller.

2021-07-30selftests/bpf: Check consistency between bpftool source, doc, completionQuentin Monnet1-0/+486
Whenever the eBPF subsystem gains new elements, such as new program or map types, it is necessary to update bpftool if we want it able to handle the new items. In addition to the main arrays containing the names of these elements in the source code, there are also multiple locations to update: - The help message in the do_help() functions in bpftool's source code. - The RST documentation files. - The bash completion file. This has led to omissions multiple times in the past. This patch attempts to address this issue by adding consistency checks for all these different locations. It also verifies that the bpf_prog_type, bpf_map_type and bpf_attach_type enums from the UAPI BPF header have all their members present in bpftool. The script requires no argument to run, it reads and parses the different files to check, and prints the mismatches, if any. It currently reports a number of missing elements, which will be fixed in a later patch: $ ./test_bpftool_synctypes.py Comparing [...]/linux/tools/bpf/bpftool/map.c (map_type_name) and [...]/linux/tools/bpf/bpftool/bash-completion/bpftool (BPFTOOL_MAP_CREATE_TYPES): {'ringbuf'} Comparing BPF header (enum bpf_attach_type) and [...]/linux/tools/bpf/bpftool/common.c (attach_type_name): {'BPF_TRACE_ITER', 'BPF_XDP_DEVMAP', 'BPF_XDP', 'BPF_SK_REUSEPORT_SELECT', 'BPF_XDP_CPUMAP', 'BPF_SK_REUSEPORT_SELECT_OR_MIGRATE'} Comparing [...]/linux/tools/bpf/bpftool/prog.c (attach_type_strings) and [...]/linux/tools/bpf/bpftool/prog.c (do_help() ATTACH_TYPE): {'skb_verdict'} Comparing [...]/linux/tools/bpf/bpftool/prog.c (attach_type_strings) and [...]/linux/tools/bpf/bpftool/Documentation/bpftool-prog.rst (ATTACH_TYPE): {'skb_verdict'} Comparing [...]/linux/tools/bpf/bpftool/prog.c (attach_type_strings) and [...]/linux/tools/bpf/bpftool/bash-completion/bpftool (BPFTOOL_PROG_ATTACH_TYPES): {'skb_verdict'} Note that the script does NOT check for consistency between the list of program types that bpftool claims it accepts and the actual list of keywords that can be used. This is because bpftool does not "see" them, they are ELF section names parsed by libbpf. It is not hard to parse the section_defs[] array in libbpf, but some section names are associated with program types that bpftool cannot load at the moment. For example, some programs require a BTF target and an attach target that bpftool cannot handle. The script may be extended to parse the array and check only relevant values in the future. The script is not added to the selftests' Makefile, because doing so would require all patches with BPF UAPI change to also update bpftool. Instead it is to be added to the CI.

2021-07-27KVM: selftests: Introduce access_tracking_perf_testDavid Matlack3-0/+431
This test measures the performance effects of KVM's access tracking. Access tracking is driven by the MMU notifiers test_young, clear_young, and clear_flush_young. These notifiers do not have a direct userspace API, however the clear_young notifier can be triggered by marking a pages as idle in /sys/kernel/mm/page_idle/bitmap. This test leverages that mechanism to enable access tracking on guest memory. To measure performance this test runs a VM with a configurable number of vCPUs that each touch every page in disjoint regions of memory. Performance is measured in the time it takes all vCPUs to finish touching their predefined region. Example invocation: $ ./access_tracking_perf_test -v 8 Testing guest mode: PA-bits:ANY, VA-bits:48, 4K pages guest physical test memory offset: 0xffdfffff000 Populating memory : 1.337752570s Writing to populated memory : 0.010177640s Reading from populated memory : 0.009548239s Mark memory idle : 23.973131748s Writing to idle memory : 0.063584496s Mark memory idle : 24.924652964s Reading from idle memory : 0.062042814s Breaking down the results: * "Populating memory": The time it takes for all vCPUs to perform the first write to every page in their region. * "Writing to populated memory" / "Reading from populated memory": The time it takes for all vCPUs to write and read to every page in their region after it has been populated. This serves as a control for the later results. * "Mark memory idle": The time it takes for every vCPU to mark every page in their region as idle through page_idle. * "Writing to idle memory" / "Reading from idle memory": The time it takes for all vCPUs to write and read to every page in their region after it has been marked idle. This test should be portable across architectures but it is only enabled for x86_64 since that's all I have tested.

The additional change to kvm-test-1-run.sh places the per-scenario number-of-CPUs information where it can easily be found. If there is some reason why affinity cannot be supplied, this commit prints and logs the reason via changes to kvm-again.sh.

There is "qemu-affinity", "qemu-cmd", "qemu-retval", but also "qemu_pid". This is hard to remember, not so good for bash tab completion, and just plain inconsistent. This commit therefore renames the "qemu_pid" file to "qemu-pid".

2021-07-23selftest: use mmap instead of posix_memalign to allocate memoryPeter Collingbourne1-2/+4
This test passes pointers obtained from anon_allocate_area to the userfaultfd and mremap APIs. This causes a problem if the system allocator returns tagged pointers because with the tagged address ABI the kernel rejects tagged addresses passed to these APIs, which would end up causing the test to fail. To make this test compatible with such system allocators, stop using the system allocator to allocate memory in anon_allocate_area, and instead just use mmap.

2021-07-23bpf: selftest: Test batching and bpf_(get|set)sockopt in bpf tcp iterMartin KaFai Lau5-9/+384
This patch adds tests for the batching and bpf_(get|set)sockopt in bpf tcp iter. It first creates: a) 1 non SO_REUSEPORT listener in lhash2. b) 256 passive and active fds connected to the listener in (a). c) 256 SO_REUSEPORT listeners in one of the lhash2 bucket. The test sets all listeners and connections to bpf_cubic before running the bpf iter. The bpf iter then calls setsockopt(TCP_CONGESTION) to switch each listener and connection from bpf_cubic to bpf_dctcp. The bpf iter has a random_retry mode such that it can return EAGAIN to the usespace in the middle of a batch.

2021-07-21selftests: net: Test for the IOAM insertion with IPv6Justin Iurman4-0/+702
This test evaluates the IOAM insertion for IPv6 by checking the IOAM data integrity on the receiver. The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between) and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only, which means not on the reverse path. When Gamma is the destination, Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM data integrity is checked on Gamma, by comparing with the pre-defined IOAM configuration (see below). +-------------------+ +-------------------+ | | | | | alpha netns | | gamma netns | | | | | | +-------------+ | | +-------------+ | | | veth0 | | | | veth0 | | | | db01::2/64 | | | | db02::2/64 | | | +-------------+ | | +-------------+ | | . | | . | +-------------------+ +-------------------+ . . . . . . +----------------------------------------------------+ | . . | | +-------------+ +-------------+ | | | veth0 | | veth1 | | | | db01::1/64 | ................ | db02::1/64 | | | +-------------+ +-------------+ | | | | beta netns | | | +--------------------------+-------------------------+ ~~~~~~~~~~~~~~~~~~~~~~ | IOAM configuration | ~~~~~~~~~~~~~~~~~~~~~~ Alpha +-----------------------------------------------------------+ | Type | Value | +-----------------------------------------------------------+ | Node ID | 1 | +-----------------------------------------------------------+ | Node Wide ID | 11111111 | +-----------------------------------------------------------+ | Ingress ID | 0xffff (default value) | +-----------------------------------------------------------+ | Ingress Wide ID | 0xffffffff (default value) | +-----------------------------------------------------------+ | Egress ID | 101 | +-----------------------------------------------------------+ | Egress Wide ID | 101101 | +-----------------------------------------------------------+ | Namespace Data | 0xdeadbee0 | +-----------------------------------------------------------+ | Namespace Wide Data | 0xcafec0caf00dc0de | +-----------------------------------------------------------+ | Schema ID | 777 | +-----------------------------------------------------------+ | Schema Data | something that will be 4n-aligned | +-----------------------------------------------------------+ Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace option inside a Hop-by-hop, where 164 bytes are pre-allocated for the trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace type (= all available options at this time). As a result, and based on IOAM configurations here, only both Alpha and Beta should be capable of inserting their IOAM data while Gamma won't have enough space and will set the overflow bit.

This commit is a first step towards pinning guest-OS vCPUs so as to force latency differences, especially on multi-socket systems.

This commit therefore moves the invocation of parse-console.sh to kvm-test-1-run.sh, which has PATH and title at hand. This commit does not add an invocation of parse-console.sh to kvm-test-1-run-batch.sh because this latter script is run in the background, and the information will be gathered at the end of the full run.
