2022-09-20selftests: seg6: add selftest for NEXT-C-SID flavor in SRv6 End behaviorAndrea Mayer2-0/+1146
This selftest is designed for testing the support of NEXT-C-SID flavor for SRv6 End behavior. It instantiates a virtual network composed of several nodes: hosts and SRv6 routers. Each node is realized using a network namespace that is properly interconnected to others through veth pairs. The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged by hosts for communicating with each other. Such routers i) apply different SRv6 Policies to the traffic received from connected hosts, considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID compression mechanism for encoding several SRv6 segments within a single 128-bit SID address, referred to as a Compressed SID (C-SID) container. The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior, enabling it to properly process the C-SID containers. The correct execution of the enabled NEXT-C-SID SRv6 End behavior is verified through reachability tests carried out between hosts belonging to the same VPN.

2022-09-19selftests: mlxsw: Add QOS test for maximum use of descriptorsAmit Cohen2-0/+296
Add an equivalent test to qos_burst, the test's purpose is same, but the new test uses simpler topology and does not require forcing low speed. In addition, it can be run Spectrum-2 and not only Spectrum-3+. The idea is to use a shaper in order to limit the traffic and create congestion. qos_burst test uses small pool, sends many small packets, and verify that packets are not dropped, which means that many descriptors can be handled. This test should check the change that commit c864769add96 ("mlxsw: Configure descriptor buffers") pushed. Instead, the new test tries to use more than 85% of maximum supported descriptors. The idea is to use big pool (as much as the ASIC supports), such that the pool size does not limit the traffic, then send many small packets, which means that many descriptors are used, and check how many packets the switch can handle. The usage of shaper allows to run the test in all ASICs, regardless of the CPU abilities, as it is able to create the congestion with low rate of packets.

2022-09-19selftests: mlxsw: Use shapers in QOS RED tests instead of forcing speedAmit Cohen3-16/+15
QOS tests create congestion and verify the switch behavior. To create congestion, they need to have more traffic than the port can handle, so some of them force 1Gbps speed. The tests assume that 1Gbps speed is supported, otherwise, they will fail. Spectrum-4 ASIC will not support this speed in all ports, so to be able to run the tests there, some adjustments are required. Use shapers to limit the traffic instead of forcing speed. Note that for several ports, the speed configuration is just for autoneg issues, so shaper is not needed instead. The tests already use ETS qdisc as a root and RED qdiscs as children. Add a new TBF shaper to limit the rate of traffic, and use it as a root qdisc, then save the previous hierarchy of qdiscs under the new TBF root. In some ASICs, the shapers do not limit the traffic as accurately as forcing speed. To make the tests stable, allow the backlog size to be up to +-10% of the threshold. The aim of the tests is to make sure that with backlog << threshold, there are no drops, and that packets are dropped somewhere in vicinity of the configured threshold.

2022-09-16selftests/bpf: Add veristat tool for mass-verifying BPF object filesAndrii Nakryiko3-1/+544
Add a small tool, veristat, that allows mass-verification of a set of *libbpf-compatible* BPF ELF object files. For each such object file, veristat will attempt to verify each BPF program *individually*. Regardless of success or failure, it parses BPF verifier stats and outputs them in human-readable table format. In the future we can also add CSV and JSON output for more scriptable post-processing, if necessary. veristat allows to specify a set of stats that should be output and ordering between multiple objects and files (e.g., so that one can easily order by total instructions processed, instead of default file name, prog name, verdict, total instructions order). This tool should be useful for validating various BPF verifier changes or even validating different kernel versions for regressions. Here's an example for some of the heaviest selftests/bpf BPF object files: $ sudo ./veristat -s insns,file,prog {pyperf,loop,test_verif_scale,strobemeta,test_cls_redirect,profiler}*.linked3.o File Program Verdict Duration, us Total insns Total states Peak states ------------------------------------ ------------------------------------ ------- ------------ ----------- ------------ ----------- loop3.linked3.o while_true failure 350990 1000001 9663 9663 test_verif_scale3.linked3.o balancer_ingress success 115244 845499 8636 2141 test_verif_scale2.linked3.o balancer_ingress success 77688 773445 3048 788 pyperf600.linked3.o on_event success 2079872 624585 30335 30241 pyperf600_nounroll.linked3.o on_event success 353972 568128 37101 2115 strobemeta.linked3.o on_event success 455230 557149 15915 13537 test_verif_scale1.linked3.o balancer_ingress success 89880 554754 8636 2141 strobemeta_nounroll2.linked3.o on_event success 433906 501725 17087 1912 loop6.linked3.o trace_virtqueue_add_sgs success 282205 398057 8717 919 loop1.linked3.o nested_loops success 125630 361349 5504 5504 pyperf180.linked3.o on_event success 2511740 160398 11470 11446 pyperf100.linked3.o on_event success 744329 87681 6213 6191 test_cls_redirect.linked3.o cls_redirect success 54087 78925 4782 903 strobemeta_subprogs.linked3.o on_event success 57898 65420 1954 403 test_cls_redirect_subprogs.linked3.o cls_redirect success 54522 64965 4619 958 strobemeta_nounroll1.linked3.o on_event success 43313 57240 1757 382 pyperf50.linked3.o on_event success 194355 46378 3263 3241 profiler2.linked3.o tracepoint__syscalls__sys_enter_kill success 23869 43372 1423 542 pyperf_subprogs.linked3.o on_event success 29179 36358 2499 2499 profiler1.linked3.o tracepoint__syscalls__sys_enter_kill success 13052 27036 1946 936 profiler3.linked3.o tracepoint__syscalls__sys_enter_kill success 21023 26016 2186 915 profiler2.linked3.o kprobe__vfs_link success 5255 13896 303 271 profiler1.linked3.o kprobe__vfs_link success 7792 12687 1042 1041 profiler3.linked3.o kprobe__vfs_link success 7332 10601 865 865 profiler2.linked3.o kprobe_ret__do_filp_open success 3417 8900 216 199 profiler2.linked3.o kprobe__vfs_symlink success 3548 8775 203 186 pyperf_global.linked3.o on_event success 10007 7563 520 520 profiler3.linked3.o kprobe_ret__do_filp_open success 4708 6464 532 532 profiler1.linked3.o kprobe_ret__do_filp_open success 3090 6445 508 508 profiler3.linked3.o kprobe__vfs_symlink success 4477 6358 521 521 profiler1.linked3.o kprobe__vfs_symlink success 3381 6347 507 507 profiler2.linked3.o raw_tracepoint__sched_process_exec success 2464 5874 292 189 profiler3.linked3.o raw_tracepoint__sched_process_exec success 2677 4363 397 283 profiler2.linked3.o kprobe__proc_sys_write success 1800 4355 143 138 profiler1.linked3.o raw_tracepoint__sched_process_exec success 1649 4019 333 240 pyperf600_bpf_loop.linked3.o on_event success 2711 3966 306 306 profiler2.linked3.o raw_tracepoint__sched_process_exit success 1234 3138 83 66 profiler3.linked3.o kprobe__proc_sys_write success 1755 2623 223 223 profiler1.linked3.o kprobe__proc_sys_write success 1222 2456 193 193 loop2.linked3.o while_true success 608 1783 57 30 profiler3.linked3.o raw_tracepoint__sched_process_exit success 789 1680 146 146 profiler1.linked3.o raw_tracepoint__sched_process_exit success 592 1526 133 133 strobemeta_bpf_loop.linked3.o on_event success 1015 1512 106 106 loop4.linked3.o combinations success 165 524 18 17 profiler3.linked3.o raw_tracepoint__sched_process_fork success 196 299 25 25 profiler1.linked3.o raw_tracepoint__sched_process_fork success 109 265 19 19 profiler2.linked3.o raw_tracepoint__sched_process_fork success 111 265 19 19 loop5.linked3.o while_true success 47 84 9 9 ------------------------------------ ------------------------------------ ------- ------------ ----------- ------------ ----------- Signed-off-by: Andrii Nakryiko <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]

2022-09-11userfaultfd: selftests: modify selftest to use /dev/userfaultfdAxel Rasmussen1-10/+66
We clearly want to ensure both userfaultfd(2) and /dev/userfaultfd keep working into the future, so just run the test twice, using each interface. Instead of always testing both userfaultfd(2) and /dev/userfaultfd, let the user choose which to test. As with other test features, change the behavior based on a new command line flag. Introduce the idea of "test mods", which are generic (not specific to a test type) modifications to the behavior of the test. This is sort of borrowed from this RFC patch series [1], but simplified a bit. The benefit is, in "typical" configurations this test is somewhat slow (say, 30sec or something). Testing both clearly doubles it, so it may not always be desirable, as users are likely to use one or the other, but never both, in the "real world".

2022-09-11selftests: vm: add hugetlb_shared userfaultfd test to run_vmtests.shAxel Rasmussen1-2/+4
Patch series "userfaultfd: add /dev/userfaultfd for fine grained access control", v7. Why not ...? ============ - Why not /proc/[pid]/userfaultfd? Two main points (additional discussion [1]): - /proc/[pid]/* files are all owned by the user/group of the process, and they don't really support chmod/chown. So, without extending procfs it doesn't solve the problem this series is trying to solve. - The main argument *for* this was to support creating UFFDs for remote processes. But, that use case clearly calls for CAP_SYS_PTRACE, so to support this we could just use the UFFD syscall as-is. - Why not use a syscall? Access to syscalls is generally controlled by capabilities. We don't have a capability which is used for userfaultfd access without also granting more / other permissions as well, and adding a new capability was rejected [2]. - It's possible a LSM could be used to control access instead, but I have some concerns. I don't think this approach would be as easy to use, particularly if we were to try to solve this with something heavyweight like SELinux. Maybe we could pursue adding a new LSM specifically for this user case, but it may be too narrow of a case to justify that. [1]: https://patchwork.kernel.org/project/linux-mm/cover/[email protected]/ [2]: https://lore.kernel.org/lkml/[email protected]/T/ This patch (of 5): This not being included was just a simple oversight. There are certain features (like minor fault support) which are only enabled on shared mappings, so without including hugetlb_shared we actually lose a significant amount of test coverage.

2022-09-11selftests/vm: add selftest to verify multi THP collapseZach O'Keefe1-67/+73
Add support to allocate and verify collapse of multiple hugepage-sized regions into multiple THPs. Add "nr" argument to check_huge() that instructs check_huge() to check for exactly "nr_hpages" THPs. This has the added benefit of now being able to check for exactly 0 THPs, and so callsites that previously checked the negation of exactly 1 THP are now more correct. ->collapse struct collapse_context hook has been expanded with a "nr_hpages" argument to collapse "nr_hpages" hugepages. The collapse_full() test has been repurposed to collapse 4 THPs at once. It is expected more tests will want to test multi THP collapse (e.g. file/shmem). This is of particular benefit to madvise collapse context given that it may do many THP collapses during a single syscall.

2022-09-11selftests/vm: dedup hugepage allocation logicZach O'Keefe1-39/+23
The code p = alloc_mapping(); printf("Allocate huge page..."); madvise(p, hpage_pmd_size, MADV_HUGEPAGE); fill_memory(p, 0, hpage_pmd_size); if (check_huge(p)) success("OK"); else fail("Fail"); Is repeated many times in different tests. Add a helper, alloc_hpage() to handle this.

2022-09-11selftests/vm: modularize collapse selftestsZach O'Keefe1-141/+110
Modularize the collapse action of khugepaged collapse selftests by introducing a struct collapse_context which specifies how to collapse a given memory range and the expected semantics of the collapse. This can be reused later to test other collapse contexts. Additionally, all tests have logic that checks if a collapse occurred via reading /proc/self/smaps, and report if this is different than expected. Move this logic into the per-context ->collapse() hook instead of repeating it in every test.
