2024-01-29KVM: selftests: Reword the NX hugepage test's skip message to be more helpfulSean Christopherson
Rework the NX hugepage test's skip message regarding the magic token to provide all of the necessary magic, and to very explicitly recommended using the wrapper shell script. Opportunistically remove an overzealous newline; splitting the recommendation message across two lines of ~45 characters makes it much harder to read than running out a single line to 98 characters.

The main changes are: 1) Add BPF token support to delegate a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. With addressed changes from Christian and Linus' reviews, from Andrii Nakryiko. 2) Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type, from Kui-Feng Lee. 3) Add support for retrieval of cookies for perf/kprobe multi links, from Jiri Olsa. 4) Bigger batch of prep-work for the BPF verifier to eventually support preserving boundaries and tracking scalars on narrowing fills, from Maxim Mikityanskiy. 5) Extend the tc BPF flavor to support arbitrary TCP SYN cookies to help with the scenario of SYN floods, from Kuniyuki Iwashima. 6) Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects, from Hou Tao. 7) Extend BPF verifier to track aligned ST stores as imprecise spilled registers, from Yonghong Song. 8) Several fixes to BPF selftests around inline asm constraints and unsupported VLA code generation, from Jose E. Marchesi. 9) Various updates to the BPF IETF instruction set draft document such as the introduction of conformance groups for instructions, from Dave Thaler. 10) Fix BPF verifier to make infinite loop detection in is_state_visited() exact to catch some too lax spill/fill corner cases, from Eduard Zingerman. 11) Refactor the BPF verifier pointer ALU check to allow ALU explicitly instead of implicitly for various register types, from Hao Sun. 12) Fix the flaky tc_redirect_dtime BPF selftest due to slowness in neighbor advertisement at setup time, from Martin KaFai Lau. 13) Change BPF selftests to skip callback tests for the case when the JIT is disabled, from Tiezhu Yang. 14) Add a small extension to libbpf which allows to auto create a map-in-map's inner map, from Andrey Grafin. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (107 commits) selftests/bpf: Add missing line break in test_verifier bpf, docs: Clarify definitions of various instructions bpf: Fix error checks against bpf_get_btf_vmlinux(). bpf: One more maintainer for libbpf and BPF selftests selftests/bpf: Incorporate LSM policy to token-based tests selftests/bpf: Add tests for LIBBPF_BPF_TOKEN_PATH envvar libbpf: Support BPF token path setting through LIBBPF_BPF_TOKEN_PATH envvar selftests/bpf: Add tests for BPF object load with implicit token selftests/bpf: Add BPF object loading tests with explicit token passing libbpf: Wire up BPF token support at BPF object level libbpf: Wire up token_fd into feature probing logic libbpf: Move feature detection code into its own file libbpf: Further decouple feature checking logic from bpf_object libbpf: Split feature detectors definitions from cached results selftests/bpf: Utilize string values for delegate_xxx mount options bpf: Support symbolic BPF FS delegation mount options bpf: Fail BPF_TOKEN_CREATE if no delegation option was set on BPF FS bpf,selinux: Allocate bpf_security_struct per BPF token selftests/bpf: Add BPF token-enabled tests libbpf: Add BPF token support to bpf_prog_load() API ... ==================== Link: https://lore.kernel.org/r/20240126215710.19855-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-01-26selftests: net: give more time for GRO aggregationPaolo Abeni
The gro.sh test-case relay on the gro_flush_timeout to ensure that all the segments belonging to any given batch are properly aggregated. The other end, the sender is a user-space program transmitting each packet with a separate write syscall. A busy host and/or stracing the sender program can make the relevant segments reach the GRO engine after the flush timeout triggers. Give the GRO flush timeout more slack, to avoid sporadic self-tests failures.

2024-01-25selftests/mm: ksm_tests should only MADV_HUGEPAGE valid memoryRyan Roberts
ksm_tests was previously mmapping a region of memory, aligning the returned pointer to a PMD boundary, then setting MADV_HUGEPAGE, but was setting it past the end of the mmapped area due to not taking the pointer alignment into consideration. Fix this behaviour. Up until commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries"), this buggy behavior was (usually) masked because the alignment difference was always less than PMD-size. But since the mentioned commit, `ksm_tests -H -s 100` started failing.

2024-01-25selftests/mm: Update va_high_addr_switch.sh to check CPU for la57 flagAudra Mitchell
In order for the page table level 5 to be in use, the CPU must have the setting enabled in addition to the CONFIG option. Check for the flag to be set to avoid false test failures on systems that do not have this cpu flag set. The test does a series of mmap calls including three using the MAP_FIXED flag and specifying an address that is 1<<47 or 1<<48. These addresses are only available if you are using level 5 page tables, which requires both the CPU to have the capabiltiy (la57 flag) and the kernel to be configured. Currently the test only checks for the kernel configuration option, so this test can still report a false positive. Here are the three failing lines: $ ./va_high_addr_switch | grep FAILED mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED mmap(HIGH_ADDR, MAP_FIXED): 0xffffffffffffffff - FAILED mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED I thought (for about a second) refactoring the test so that these three mmap calls will only be run on systems with the level 5 page tables available, but the whole point of the test is to check the level 5 feature...

On systems with 64k page size and 512M huge page sizes, the allocation and test succeeds but errors out at the munmap. As the comment states, munmap will failure if its not HUGEPAGE aligned. This is due to the length of the mapping being 1/2 the size of the hugepage causing the munmap to not be hugepage aligned. Fix this by making the mapping length the full hugepage if the hugepage is larger than the length of the mapping.

2024-01-24selftests/bpf: Add BPF token-enabled testsAndrii Nakryiko
Add a selftest that attempts to conceptually replicate intended BPF token use cases inside user namespaced container. Child process is forked. It is then put into its own userns and mountns. Child creates BPF FS context object. This ensures child userns is captured as the owning userns for this instance of BPF FS. Given setting delegation mount options is privileged operation, we ensure that child cannot set them. This context is passed back to privileged parent process through Unix socket, where parent sets up delegation options, creates, and mounts it as a detached mount. This mount FD is passed back to the child to be used for BPF token creation, which allows otherwise privileged BPF operations to succeed inside userns. We validate that all of token-enabled privileged commands (BPF_BTF_LOAD, BPF_MAP_CREATE, and BPF_PROG_LOAD) work as intended. They should only succeed inside the userns if a) BPF token is provided with proper allowed sets of commands and types; and b) namespaces CAP_BPF and other privileges are set. Lacking a) or b) should lead to -EPERM failures. Based on suggested workflow by Christian Brauner ([0]).
