====================
pull-request: bpf-next 2023-10-26

We've added 51 non-merge commits during the last 10 day(s) which contain
a total of 75 files changed, 5037 insertions(+), 200 deletions(-).

The main changes are:

1) Add open-coded task, css_task and css iterator support.
   One of the use cases is customizable OOM victim selection via BPF,
   from Chuyi Zhou.

2) Fix BPF verifier's iterator convergence logic to use exact states
   comparison for convergence checks, from Eduard Zingerman,
   Andrii Nakryiko and Alexei Starovoitov.

3) Add BPF programmable net device where bpf_mprog defines the logic
   of its xmit routine. It can operate in L3 and L2 mode,
   from Daniel Borkmann and Nikolay Aleksandrov.

4) Batch of fixes for BPF per-CPU kptr and re-enable unit_size checking
   for global per-CPU allocator, from Hou Tao.

5) Fix libbpf which eagerly assumed that SHT_GNU_verdef ELF section
   was going to be present whenever a binary has SHT_GNU_versym section,
   from Andrii Nakryiko.

6) Fix BPF ringbuf correctness to fold smp_mb__before_atomic() into
   atomic_set_release(), from Paul E. McKenney.

7) Add a warning if NAPI callback missed xdp_do_flush() under
   CONFIG_DEBUG_NET which helps checking if drivers were missing
   the former, from Sebastian Andrzej Siewior.

8) Fix missed RCU read-lock in bpf_task_under_cgroup() which was throwing
   a warning under sleepable programs, from Yafang Shao.

9) Avoid unnecessary -EBUSY from htab_lock_bucket by disabling IRQ before
   checking map_locked, from Song Liu.

10) Make BPF CI linked_list failure test more robust,
    from Kumar Kartikeya Dwivedi.

11) Enable samples/bpf to be built as PIE in Fedora, from Viktor Malik.

12) Fix xsk starving when multiple xsk sockets were associated with
    a single xsk_buff_pool, from Albert Huang.

13) Clarify the signed modulo implementation for the BPF ISA standardization
    document that it uses truncated division, from Dave Thaler.

14) Improve BPF verifier's JEQ/JNE branch taken logic to also consider
    signed bounds knowledge, from Andrii Nakryiko.

15) Add an option to XDP selftests to use multi-buffer AF_XDP
    xdp_hw_metadata and mark used XDP programs as capable to use frags,
    from Larysa Zaremba.

16) Fix bpftool's BTF dumper wrt printing a pointer value and another
    one to fix struct_ops dump in an array, from Manu Bretelle.
