The main changes are: 1) Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses, from Joanne Koong. 2) Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities, from Andrii Nakryiko. 3) Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc, from Alexei Starovoitov. 4) Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps, from Kumar Kartikeya Dwivedi. 5) Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them, from Eduard Zingerman. 6) Make uprobe attachment Android APK aware by supporting attachment to functions inside ELF objects contained in APKs via function names, from Daniel Müller. 7) Add a new flag BPF_F_TIMER_ABS flag for bpf_timer_start() helper to start the timer with absolute expiration value instead of relative one, from Tero Kristo. 8) Add a new kfunc bpf_cgroup_from_id() to look up cgroups via id, from Tejun Heo. 9) Extend libbpf to support users manually attaching kprobes/uprobes in the legacy/perf/link mode, from Menglong Dong. 10) Implement workarounds in the mips BPF JIT for DADDI/R4000, from Jiaxun Yang. 11) Enable mixing bpf2bpf and tailcalls for the loongarch BPF JIT, from Hengqi Chen. 12) Extend BPF instruction set doc with describing the encoding of BPF instructions in terms of how bytes are stored under big/little endian, from Jose E. Marchesi. 13) Follow-up to enable kfunc support for riscv BPF JIT, from Pu Lehui. 14) Fix bpf_xdp_query() backwards compatibility on old kernels, from Yonghong Song. 15) Fix BPF selftest cross compilation with CLANG_CROSS_FLAGS, from Florent Revest. 16) Improve bpf_cpumask_ma to only allocate one bpf_mem_cache, from Hou Tao. 17) Fix BPF verifier's check_subprogs to not unnecessarily mark a subprogram with has_tail_call, from Ilya Leoshkevich. 18) Fix arm syscall regs spec in libbpf's bpf_tracing.h, from Puranjay Mohan. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (85 commits) selftests/bpf: Add test for legacy/perf kprobe/uprobe attach mode selftests/bpf: Split test_attach_probe into multi subtests libbpf: Add support to set kprobe/uprobe attach mode tools/resolve_btfids: Add /libsubcmd to .gitignore bpf: add support for fixed-size memory pointer returns for kfuncs bpf: generalize dynptr_get_spi to be usable for iters bpf: mark PTR_TO_MEM as non-null register type bpf: move kfunc_call_arg_meta higher in the file bpf: ensure that r0 is marked scratched after any function call bpf: fix visit_insn()'s detection of BPF_FUNC_timer_set_callback helper bpf: clean up visit_insn()'s instruction processing selftests/bpf: adjust log_fixup's buffer size for proper truncation bpf: honor env->test_state_freq flag in is_state_visited() selftests/bpf: enhance align selftest's expected log matching bpf: improve regsafe() checks for PTR_TO_{MEM,BUF,TP_BUFFER} bpf: improve stack slot state printing selftests/bpf: Disassembler tests for verifier.c:convert_ctx_access() selftests/bpf: test if pointer type is tracked for BPF_ST_MEM bpf: allow ctx writes using BPF_ST_MEM instruction bpf: Use separate RCU callbacks for freeing selem ... ==================== Link: https://lore.kernel.org/r/20230307004346.27578-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
