====================
pull-request: bpf-next 2023-04-21
We've added 71 non-merge commits during the last 8 day(s) which contain
a total of 116 files changed, 13397 insertions(+), 8896 deletions(-).
The main changes are:
1) Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward,
from Florian Westphal.
2) Fix race between btf_put and btf_idr walk which caused a deadlock,
from Alexei Starovoitov.
3) Second big batch to migrate test_verifier unit tests into test_progs
for ease of readability and debugging, from Eduard Zingerman.
4) Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree, from Dave Marchevsky.
5) Migrate bpf_for(), bpf_for_each() and bpf_repeat() macros from BPF
selftests into libbpf-provided bpf_helpers.h header and improve
kfunc handling, from Andrii Nakryiko.
6) Support 64-bit pointers to kfuncs needed for archs like s390x,
from Ilya Leoshkevich.
7) Support BPF progs under getsockopt with a NULL optval,
from Stanislav Fomichev.
8) Improve verifier u32 scalar equality checking in order to enable
LLVM transformations which earlier had to be disabled specifically
for BPF backend, from Yonghong Song.
9) Extend bpftool's struct_ops object loading to support links,
from Kui-Feng Lee.
10) Add xsk selftest follow-up fixes for hugepage allocated umem,
from Magnus Karlsson.
11) Support BPF redirects from tc BPF to ifb devices,
from Daniel Borkmann.
12) Add BPF support for integer type when accessing variable length
arrays, from Feng Zhou.
