Merge tag 'bpf-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf

Pull BPF fixes from Daniel Borkmann:

 - 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)
