Pull networking updates from Paolo Abeni:
"Core:

- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with
large writes operations

- Improve sched class lifetime handling

- Add backup nexthop ID support for bridge

- Implement drop reasons support in openvswitch

- Several data races annotations and fixes

- Constify the sk parameter of routing functions

- Prepend kernel version to netconsole message

Protocols:

- Implement support for TCP probing the peer being under memory
pressure

- Remove hard coded limitation on IPv6 specific info placement inside
the socket struct

expiring routes

common information already populated in struct genl_info

- Extend and use the yaml devlink specs to [re]generate the split ops

- Introduce devlink selective dumps, to allow SF filtering SF based
on handle and other attributes

====================
pull-request: bpf-next 2023-08-25

We've added 87 non-merge commits during the last 8 day(s) which contain
a total of 104 files changed, 3719 insertions(+), 4212 deletions(-).

The main changes are:

1) Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds,
from Jiri Olsa.

2) Add support BPF cpu v4 instructions for arm64 JIT compiler,
from Xu Kuohai.

3) Add support BPF cpu v4 instructions for riscv64 JIT compiler,
from Pu Lehui.

4) Fix LWT BPF xmit hooks wrt their return values where propagating
the result from skb_do_redirect() would trigger a use-after-free,
from Yan Zhai.

5) Fix a BPF verifier issue related to bpf_kptr_xchg() with local kptr
where the map's value kptr type and locally allocated obj type
mismatch, from Yonghong Song.

6) Fix BPF verifier's check_func_arg_reg_off() function wrt graph
root/node which bypassed reg->off == 0 enforcement,
from Kumar Kartikeya Dwivedi.

7) Lift BPF verifier restriction in networking BPF programs to treat
comparison of packet pointers not as a pointer leak,
from Yafang Shao.

8) Remove unmaintained XDP BPF samples as they are maintained
in xdp-tools repository out of tree, from Toke Høiland-Jørgensen.

9) Batch of fixes for the tracing programs from BPF samples in order
to make them more libbpf-aware, from Daniel T. Lee.

10) Fix a libbpf signedness determination bug in the CO-RE relocation
handling logic, from Andrii Nakryiko.

11) Extend libbpf to support CO-RE kfunc relocations. Also follow-up
fixes for bpf_refcount shared ownership implementation,
both from Dave Marchevsky.

12) Add a new bpf_object__unpin() API function to libbpf,
from Daniel Xu.

13) Fix a memory leak in libbpf to also free btf_vmlinux
when the bpf_object gets closed, from Hao Luo.

14) Small error output improvements to test_bpf module, from Helge Deller.

Merge branch 'bpf-support-new-insns-from-cpu-v4'

Yonghong Song says:

====================
bpf: Support new insns from cpu v4

In previous discussion ([1]), it is agreed that we should introduce
cpu version 4 (llvm flag -mcpu=v4) which contains some instructions
which can simplify code, make code easier to understand, fix the
existing problem, or simply for feature completeness. More specifically,
the following new insns are proposed:
. sign extended load
. sign extended mov
. bswap
. signed div/mod
. ja with 32-bit offset

This patch set added kernel support for insns proposed in [1] except
BPF_ST which already has full kernel support. Beside the above proposed
insns, LLVM will generate BPF_ST insn as well under -mcpu=v4.
The llvm patch ([2]) has been merged into llvm-project 'main' branch.

The patchset implements interpreter, jit and verifier support for these new
insns.

For this patch set, I tested cpu v2/v3/v4 and the selftests are all passed.
I also tested selftests introduced in this patch set with additional changes
beside normal jit testing (bpf_jit_enable = 1 and bpf_jit_harden = 0)
- bpf_jit_enable = 0
- bpf_jit_enable = 1 and bpf_jit_harden = 1
and both testing passed.

[2] https://reviews.llvm.org/D144829

Changelogs:
v4 -> v5:
. for v4, patch 8/17 missed in mailing list and patchwork, so resend.
. rebase on top of master
v3 -> v4:
. some minor asm syntax adjustment based on llvm change.
. add clang version and target arch guard for new tests
so they can still compile with old llvm compilers.
. some changes to the bpf doc.
v2 -> v3:
. add missed disasm change from v2.
. handle signed load of ctx fields properly.
. fix some interpreter sdiv/smod error when bpf_jit_enable = 0.
. fix some verifier range bounding errors.
. add more C tests.
RFCv1 -> v2:
. add more verifier supports for signed extend load and mov insns.
. rename some insn names to be more consistent with intel practice.
. add cpuv4 test runner for test progs.
. add more unit and C tests.
. add documentation.
