  Merge branch 'bpf-skip-non-exist-keys-in-generic_map_lookup_batch' (2025-02-18 17:27:38 -0800)

----------------------------------------------------------------
BPF fixes:

- Fix a soft-lockup in BPF arena_map_free on 64k page size
  kernels (Alan Maguire)

- Fix a missing allocation failure check in BPF verifier's
  acquire_lock_state (Kumar Kartikeya Dwivedi)

- Fix a NULL-pointer dereference in trace_kfree_skb by adding
  kfree_skb to the raw_tp_null_args set (Kuniyuki Iwashima)

- Fix a deadlock when freeing BPF cgroup storage (Abel Wu)

- Fix a syzbot-reported deadlock when holding BPF map's
  freeze_mutex (Andrii Nakryiko)

- Fix a use-after-free issue in bpf_test_init when
  eth_skb_pkt_type is accessing skb data not containing an
  Ethernet header (Shigeru Yoshida)

- Fix skipping non-existing keys in generic_map_lookup_batch
  (Yan Zhai)

- Several BPF sockmap fixes to address incorrect TCP copied_seq
  calculations, which prevented correct data reads from recv(2)
  in user space (Jiayuan Chen)

- Two fixes for BPF map lookup nullness elision (Daniel Xu)

- Fix a NULL-pointer dereference from vmlinux BTF lookup in
  bpf_sk_storage_tracing_allowed (Jared Kangas)
