Subject: pull-request: bpf-next 2024-05-28

Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net-next* tree.

We've added 23 non-merge commits during the last 11 day(s) which contain
a total of 45 files changed, 696 insertions(+), 277 deletions(-).

The main changes are:

1) Rename skb's mono_delivery_time to tstamp_type for extensibility and add
   SKB_CLOCK_TAI type support to bpf_skb_set_tstamp(), from Abhishek Chauhan.

2) Add netfilter CT zone ID and direction to bpf_ct_opts so that arbitrary CT zones
   can be used from XDP/tc BPF netfilter CT helper functions, from Brad Cowie.

3) Several tweaks to the instruction-set.rst IETF doc to address the Last Call
   review comments, from Dave Thaler.

4) Small batch of riscv64 BPF JIT optimizations in order to emit more compressed
   instructions to the JITed image for better icache efficiency, from Xiao Wang.

5) Sort bpftool C dump output from BTF, aiming to simplify vmlinux.h diffing and
   forcing more natural type definitions ordering, from Mykyta Yatsenko.

6) Use DEV_STATS_INC() macro in BPF redirect helpers to silence a syzbot/KCSAN
   race report for the tx_errors counter, from Jiang Yunshui.

7) Un-constify bpf_func_info in bpftool to fix compilation with LLVM 17+ which
   started treating const structs as constants and thus breaking full BTF program
   name resolution, from Ivan Babrou.

8) Fix up BPF program numbers in test_sockmap selftest in order to reduce some
   of the test-internal array sizes, from Geliang Tang.

9) Small cleanup in Makefile.btf script to use test-ge check for v1.25-only
   pahole, from Alan Maguire.

10) Fix bpftool's make dependencies for vmlinux.h in order to avoid needless
    rebuilds in some corner cases, from Artem Savkov.
