Hi David, hi Jakub, hi Paolo, hi Eric,
The following pull-request contains BPF updates for your *net-next* tree.
We've added 113 non-merge commits during the last 26 day(s) which contain
a total of 121 files changed, 7425 insertions(+), 1586 deletions(-).
There is a trivial merge conflict in net/core/sysctl_net_core.c between
commits 4c7f24f857c7 ("net: sysctl: introduce sysctl SYSCTL_THREE") from
net-next and f922c8972fb5 ("net: sysctl: Use SYSCTL_TWO instead of &two")
from bpf-next. To resolve it, just remove the 'static int three = 3;'.
The main changes are:
1) Speed up symbol resolution for kprobes multi-link attachments, from Jiri Olsa.
2) Add BPF dynamic pointer infrastructure e.g. to allow for dynamically sized ringbuf
reservations without extra memory copies, from Joanne Koong.
3) Big batch of libbpf improvements towards libbpf 1.0 release, from Andrii Nakryiko.
4) Add BPF link iterator to traverse links via seq_file ops, from Dmitrii Dolgov.
5) Add source IP address to BPF tunnel key infrastructure, from Kaixi Fan.
6) Refine unprivileged BPF to disable only object-creating commands, from Alan Maguire.
7) Fix JIT blinding of ld_imm64 when they point to subprogs, from Alexei Starovoitov.
8) Add BPF access to mptcp_sock structures and their meta data, from Geliang Tang.
9) Add new BPF helper for access to remote CPU's BPF map elements, from Feng Zhou.
10) Allow attaching 64-bit cookie to BPF link of fentry/fexit/fmod_ret, from Kui-Feng Lee.
11) Follow-ups to typed pointer support in BPF maps, from Kumar Kartikeya Dwivedi.
12) Add busy-poll test cases to the XSK selftest suite, from Magnus Karlsson.
13) Improvements in BPF selftest test_progs subtest output, from Mykola Lysenko.
14) Fill bpf_prog_pack allocator areas with illegal instructions, from Song Liu.
15) Add generic batch operations for BPF map-in-map cases, from Takshak Chahande.
16) Make bpf_jit_enable more user friendly when permanently on 1, from Tiezhu Yang.
17) Fix an array overflow in bpf_trampoline_get_progs(), from Yuntao Wang.
