2023-08-18selftests: cgroup: add zswap-memcg unwanted writeback testDomenico Cerasuolo
Add a test to verify that when a memcg hits its limit in zswap, it doesn't trigger an unwanted writeback that would result in pages not owned by that memcg to be sent to disk, even if zswap isn't full. This was fixed by commit 0bdf0efa180a("zswap: do not shrink if cgroup may not zswap").

2023-08-18selftests: cgroup: add test_zswap with no kmem bypass testDomenico Cerasuolo
Add a cgroup selftest that verifies memcg charging in zswap. The original issue was that kmem bypass was applied to pages swapped out to zswap by kswapd, resulting in zswapped memory not being charged. It was fixed by commit cd08d80ecdac("mm: correctly charge compressed memory to its memcg").

2023-08-18selftests: cgroup: add test_zswap programDomenico Cerasuolo
Patch series "selftests: cgroup: add zswap test program". This series adds 2 zswap related selftests that verify known and fixed issues. A new dedicated test program (test_zswap) is proposed since the test cases are specific to zswap and hosts specific helpers. The first patch adds the (empty) test program, while the other 2 add an actual test function each. This patch (of 3): Add empty cgroup-zswap self test scaffold program, test functions to be added in the next commits.

2023-08-18selftests/mm: add gup test matrix in run_vmtests.shPeter Xu
Add a matrix for testing gup based on the current gup_test. Only run the matrix when -a is specified because it's a bit slow. It covers: - Different types of huge pages: thp, hugetlb, or no huge page - Permissions: Write / Read-only - Fast-gup, with/without - Types of the GUP: pin / gup / longterm pins - Shared / Private memories - GUP size: 1 / 512 / random page sizes Link: https://lkml.kernel.org/r/20230628215310.73782-9-peterx@redhat.com Signed-off-by: Peter Xu <peterx@redhat.com> Acked-by: David Hildenbrand <david@redhat.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Hugh Dickins <hughd@google.com> Cc: James Houghton <jthoughton@google.com> Cc: Jason Gunthorpe <jgg@nvidia.com> Cc: John Hubbard <jhubbard@nvidia.com> Cc: Kirill A .

2023-08-18selftests/bpf: Add CO-RE relocs kfunc flavors testsDave Marchevsky
This patch adds selftests that exercise kfunc flavor relocation functionality added in the previous patch. The actual kfunc defined in kernel/bpf/helpers.c is: struct task_struct *bpf_task_acquire(struct task_struct *p) The following relocation behaviors are checked: struct task_struct *bpf_task_acquire___one(struct task_struct *name) * Should succeed despite differing param name struct task_struct *bpf_task_acquire___two(struct task_struct *p, void *ctx) * Should fail because there is no two-param bpf_task_acquire struct task_struct *bpf_task_acquire___three(void *ctx) * Should fail because, despite vmlinux's bpf_task_acquire having one param, the types don't match Signed-off-by: Dave Marchevsky <davemarchevsky@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: David Vernet <void@manifault.com> Link: https://lore.kernel.org/bpf/20230817225353.2570845-2-davemarchevsky@fb.com
2023-08-18kselftest/arm64: Fix hwcaps selftest buildMark Brown
The hwcaps selftest currently relies on the assembler being able to assemble the crc32w instruction but this is not in the base v8.0 so is not accepted by the standard GCC configurations used by many distributions. Switch to manually encoding to fix the build.

There is no lwt test case for BPF_REROUTE yet. Add test cases for both normal and abnormal situations. The abnormal situation is set up with an fq qdisc on the reroute target device. Without proper fixes, overflow this qdisc queue limit (to trigger a drop) would panic the kernel.

Add custom "__kvm_pmu_event_filter" structure to improve pmu event filter settings. Simplifies event filter setup by organizing event filter parameters in a cleaner, more organized way. Alternatively, selftests could use a struct overlay ala vcpu_set_msr() to avoid dynamically allocating the array: struct { struct kvm_msrs header; struct kvm_msr_entry entry; } buffer = {}; memset(&buffer, 0, sizeof(buffer)); buffer.header.nmsrs = 1; buffer.entry.index = msr_index; buffer.entry.data = msr_value; but the extra layer added by the nested structs is counterproductive to writing efficient, clean code.

Implement a new test program mptcpify: if the family is AF_INET or AF_INET6, the type is SOCK_STREAM, and the protocol ID is 0 or IPPROTO_TCP, set it to IPPROTO_MPTCP. It will be hooked in update_socket_protocol(). Extend the MPTCP test base, add a selftest test_mptcpify() for the mptcpify case. Open and load the mptcpify test prog to mptcpify the TCP sockets dynamically, then use start_server() and connect_to_fd() to create a TCP socket, but actually what's created is an MPTCP socket, which can be verified through 'getsockopt(SOL_PROTOCOL)' and 'getsockopt(MPTCP_INFO)'.

2023-08-15selftests: seg6: add selftest for NEXT-C-SID flavor in SRv6 End.X behaviorPaolo Lungaroni
This selftest is designed for testing the support of NEXT-C-SID flavor for SRv6 End.X 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, according to the topology depicted in the selftest script file. 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.X behavior, enabling it to properly process the C-SID containers. The correct execution of the enabled NEXT-C-SID SRv6 End.X behavior is verified through reachability tests carried out between hosts belonging to the same VPN.

2023-08-14selftests/bpf: Add various more tcx test casesDaniel Borkmann
Add several new tcx test cases to improve test coverage. This also includes a few new tests with ingress instead of clsact qdisc, to cover the fix from commit dc644b540a2d ("tcx: Fix splat in ingress_destroy upon tcx_entry_free"). # ./test_progs -t tc [...] #234 tc_links_after:OK #235 tc_links_append:OK #236 tc_links_basic:OK #237 tc_links_before:OK #238 tc_links_chain_classic:OK #239 tc_links_chain_mixed:OK #240 tc_links_dev_cleanup:OK #241 tc_links_dev_mixed:OK #242 tc_links_ingress:OK #243 tc_links_invalid:OK #244 tc_links_prepend:OK #245 tc_links_replace:OK #246 tc_links_revision:OK #247 tc_opts_after:OK #248 tc_opts_append:OK #249 tc_opts_basic:OK #250 tc_opts_before:OK #251 tc_opts_chain_classic:OK #252 tc_opts_chain_mixed:OK #253 tc_opts_delete_empty:OK #254 tc_opts_demixed:OK #255 tc_opts_detach:OK #256 tc_opts_detach_after:OK #257 tc_opts_detach_before:OK #258 tc_opts_dev_cleanup:OK #259 tc_opts_invalid:OK #260 tc_opts_mixed:OK #261 tc_opts_prepend:OK #262 tc_opts_replace:OK #263 tc_opts_revision:OK [...] Summary: 44/38 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/r/8699efc284b75ccdc51ddf7062fa2370330dc6c0.1692029283.git.daniel@iogearbox.net Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>

2023-08-14selftests: mirror_gre_changes: Tighten up the TTL test matchPetr Machata
This test verifies whether the encapsulated packets have the correct configured TTL. It does so by sending ICMP packets through the test topology and mirroring them to a gretap netdevice. On a busy host however, more than just the test ICMP packets may end up flowing through the topology, get mirrored, and counted. This leads to potential spurious failures as the test observes much more mirrored packets than the sent test packets, and assumes a bug. Fix this by tightening up the mirror action match. Change it from matchall to a flower classifier matching on ICMP packets specifically.
