2023-10-19bpf, docs: Define signed modulo as using truncated divisionDave Thaler1-0/+8
There's different mathematical definitions (truncated, floored, rounded, etc.) and different languages have chosen different definitions [0][1]. E.g., languages/libraries that follow Knuth use a different mathematical definition than C uses. This patch specifies which definition BPF uses, as verified by Eduard [2] and others.

The main changes are: 1) Add missed stats for kprobes to retrieve the number of missed kprobe executions and subsequent executions of BPF programs, from Jiri Olsa. 2) Add cgroup BPF sockaddr hooks for unix sockets. The use case is for systemd to reimplement the LogNamespace feature which allows running multiple instances of systemd-journald to process the logs of different services, from Daan De Meyer. 3) Implement BPF CPUv4 support for s390x BPF JIT, from Ilya Leoshkevich. 4) Improve BPF verifier log output for scalar registers to better disambiguate their internal state wrt defaults vs min/max values matching, from Andrii Nakryiko. 5) Extend the BPF fib lookup helpers for IPv4/IPv6 to support retrieving the source IP address with a new BPF_FIB_LOOKUP_SRC flag, from Martynas Pumputis. 6) Add support for open-coded task_vma iterator to help with symbolization for BPF-collected user stacks, from Dave Marchevsky. 7) Add libbpf getters for accessing individual BPF ring buffers which is useful for polling them individually, for example, from Martin Kelly. 8) Extend AF_XDP selftests to validate the SHARED_UMEM feature, from Tushar Vyavahare. 9) Improve BPF selftests cross-building support for riscv arch, from Björn Töpel. 10) Add the ability to pin a BPF timer to the same calling CPU, from David Vernet. 11) Fix libbpf's bpf_tracing.h macros for riscv to use the generic implementation of PT_REGS_SYSCALL_REGS() to access syscall arguments, from Alexandre Ghiti. 12) Extend libbpf to support symbol versioning for uprobes, from Hengqi Chen. 13) Fix bpftool's skeleton code generation to guarantee that ELF data is 8 byte aligned, from Ian Rogers. 14) Inherit system-wide cpu_mitigations_off() setting for Spectre v1/v4 security mitigations in BPF verifier, from Yafang Shao. 15) Annotate struct bpf_stack_map with __counted_by attribute to prepare BPF side for upcoming __counted_by compiler support, from Kees Cook. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (90 commits) bpf: Ensure proper register state printing for cond jumps bpf: Disambiguate SCALAR register state output in verifier logs selftests/bpf: Make align selftests more robust selftests/bpf: Improve missed_kprobe_recursion test robustness selftests/bpf: Improve percpu_alloc test robustness selftests/bpf: Add tests for open-coded task_vma iter bpf: Introduce task_vma open-coded iterator kfuncs selftests/bpf: Rename bpf_iter_task_vma.c to bpf_iter_task_vmas.c bpf: Don't explicitly emit BTF for struct btf_iter_num bpf: Change syscall_nr type to int in struct syscall_tp_t net/bpf: Avoid unused "sin_addr_len" warning when CONFIG_CGROUP_BPF is not set bpf: Avoid unnecessary audit log for CPU security mitigations selftests/bpf: Add tests for cgroup unix socket address hooks selftests/bpf: Make sure mount directory exists documentation/bpf: Document cgroup unix socket address hooks bpftool: Add support for cgroup unix socket address hooks libbpf: Add support for cgroup unix socket address hooks bpf: Implement cgroup sockaddr hooks for unix sockets bpf: Add bpf_sock_addr_set_sun_path() to allow writing unix sockaddr from bpf bpf: Propagate modified uaddrlen from cgroup sockaddr programs ... ==================== Link: https://lore.kernel.org/r/20231016204803.30153-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-10-17tcp: Set pingpong threshold via sysctlHaiyang Zhang1-0/+13
TCP pingpong threshold is 1 by default. But some applications, like SQL DB may prefer a higher pingpong threshold to activate delayed acks in quick ack mode for better performance. The pingpong threshold and related code were changed to 3 in the year 2019 in: commit 4a41f453bedf ("tcp: change pingpong threshold to 3") And reverted to 1 in the year 2022 in: commit 4d8f24eeedc5 ("Revert "tcp: change pingpong threshold to 3"") There is no single value that fits all applications. Add net.ipv4.tcp_pingpong_thresh sysctl tunable, so it can be tuned for optimal performance based on the application needs.

The 'msi' child node schema is missing constraints on additional properties. It turns out it is incomplete and properties for it are documented in the parent node by mistake. Move the reference to msi-controller.yaml and the custom properties to the 'msi' node. Adding 'unevaluatedProperties' ensures all the properties in the 'msi' node are documented. With the schema corrected, a minimal interrupt controller node is needed to properly decode the interrupt properties since the example has multiple interrupt parents.

Timerlat auto-analysis: - Timerlat is reporting thread interference time without thread noise events occurrence. It was caused because the thread interference variable was not reset after the analysis of a timerlat activation that did not hit the threshold. - The IRQ handler delay is estimated from the delta of the IRQ latency reported by timerlat, and the timestamp from IRQ handler start event. If the delta is near-zero, the drift from the external clock and the trace event and/or the overhead can cause the value to be negative. If the value is negative, print a zero-delay. - IRQ handlers happening after the timerlat thread event but before the stop tracing were being reported as IRQ that happened before the *current* IRQ occurrence. Ignore Previous IRQ noise in this condition because they are valid only for the *next* timerlat activation. Timerlat user-space: - Timerlat is stopping all user-space thread if a CPU becomes offline.

2023-10-04net: add sysctl to disable rfc4862 5.5.3e lifetime handlingPatrick Rohr1-0/+11
This change adds a sysctl to opt-out of RFC4862 section 5.5.3e's valid lifetime derivation mechanism. RFC4862 section 5.5.3e prescribes that the valid lifetime in a Router Advertisement PIO shall be ignored if it less than 2 hours and to reset the lifetime of the corresponding address to 2 hours. An in-progress 6man draft (see draft-ietf-6man-slaac-renum-07 section 4.2) is currently looking to remove this mechanism. While this draft has not been moving particularly quickly for other reasons, there is widespread consensus on section 4.2 which updates RFC4862 section 5.5.3e.
