Daniel Borkmann says: ==================== bpf-next 2022-07-22 We've added 73 non-merge commits during the last 12 day(s) which contain a total of 88 files changed, 3458 insertions(+), 860 deletions(-). The main changes are: 1) Implement BPF trampoline for arm64 JIT, from Xu Kuohai. 2) Add ksyscall/kretsyscall section support to libbpf to simplify tracing kernel syscalls through kprobe mechanism, from Andrii Nakryiko. 3) Allow for livepatch (KLP) and BPF trampolines to attach to the same kernel function, from Song Liu & Jiri Olsa. 4) Add new kfunc infrastructure for netfilter's CT e.g. to insert and change entries, from Kumar Kartikeya Dwivedi & Lorenzo Bianconi. 5) Add a ksym BPF iterator to allow for more flexible and efficient interactions with kernel symbols, from Alan Maguire. 6) Bug fixes in libbpf e.g. for uprobe binary path resolution, from Dan Carpenter. 7) Fix BPF subprog function names in stack traces, from Alexei Starovoitov. 8) libbpf support for writing custom perf event readers, from Jon Doron. 9) Switch to use SPDX tag for BPF helper man page, from Alejandro Colomar. 10) Fix xsk send-only sockets when in busy poll mode, from Maciej Fijalkowski. 11) Reparent BPF maps and their charging on memcg offlining, from Roman Gushchin. 12) Multiple follow-up fixes around BPF lsm cgroup infra, from Stanislav Fomichev. 13) Use bootstrap version of bpftool where possible to speed up builds, from Pu Lehui. 14) Cleanup BPF verifier's check_func_arg() handling, from Joanne Koong. 15) Make non-prealloced BPF map allocations low priority to play better with memcg limits, from Yafang Shao. 16) Fix BPF test runner to reject zero-length data for skbs, from Zhengchao Shao. 17) Various smaller cleanups and improvements all over the place. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (73 commits) bpf: Simplify bpf_prog_pack_[size|mask] bpf: Support bpf_trampoline on functions with IPMODIFY (e.g. livepatch) bpf, x64: Allow to use caller address from stack ftrace: Allow IPMODIFY and DIRECT ops on the same function ftrace: Add modify_ftrace_direct_multi_nolock bpf/selftests: Fix couldn't retrieve pinned program in xdp veth test bpf: Fix build error in case of !CONFIG_DEBUG_INFO_BTF selftests/bpf: Fix test_verifier failed test in unprivileged mode selftests/bpf: Add negative tests for new nf_conntrack kfuncs selftests/bpf: Add tests for new nf_conntrack kfuncs selftests/bpf: Add verifier tests for trusted kfunc args net: netfilter: Add kfuncs to set and change CT status net: netfilter: Add kfuncs to set and change CT timeout net: netfilter: Add kfuncs to allocate and insert CT net: netfilter: Deduplicate code in bpf_{xdp,skb}_ct_lookup bpf: Add documentation for kfuncs bpf: Add support for forcing kfunc args to be trusted bpf: Switch to new kfunc flags infrastructure tools/resolve_btfids: Add support for 8-byte BTF sets bpf: Introduce 8-byte BTF set ... ==================== Link: https://lore.kernel.org/r/20220722221218.29943-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
