Merge tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Daniel Borkmann says:

====================
pull-request: bpf-next 2024-09-11

We've added 12 non-merge commits during the last 16 day(s) which contain
a total of 20 files changed, 228 insertions(+), 30 deletions(-).

There's a minor merge conflict in drivers/net/netkit.c:
  00d066a4d4 ("netdev_features: convert NETIF_F_LLTX to dev->lltx")
  d966087948 ("netkit: Disable netpoll support")

The main changes are:

1) Enable bpf_dynptr_from_skb for tp_btf such that this can be used
   to easily parse skbs in BPF programs attached to tracepoints,
   from Philo Lu.

2) Add a cond_resched() point in BPF's sock_hash_free() as there have
   been several syzbot soft lockup reports recently, from Eric Dumazet.

3) Fix xsk_buff_can_alloc() to account for queue_empty_descs which
   got noticed when zero copy ice driver started to use it,
   from Maciej Fijalkowski.

4) Move the xdp:xdp_cpumap_kthread tracepoint before cpumap pushes skbs
   up via netif_receive_skb_list() to better measure latencies,
   from Daniel Xu.

5) Follow-up to disable netpoll support from netkit, from Daniel Borkmann.

6) Improve xsk selftests to not assume a fixed MAX_SKB_FRAGS of 17 but
   instead gather the actual value via /proc/sys/net/core/max_skb_frags,
   also from Maciej Fijalkowski.

* tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next:
  sock_map: Add a cond_resched() in sock_hash_free()
  selftests/bpf: Expand skb dynptr selftests for tp_btf
  bpf: Allow bpf_dynptr_from_skb() for tp_btf
  tcp: Use skb__nullable in trace_tcp_send_reset
  selftests/bpf: Add test for __nullable suffix in tp_btf
  bpf: Support __nullable argument suffix for tp_btf
  bpf, cpumap: Move xdp:xdp_cpumap_kthread tracepoint before rcv
  selftests/xsk: Read current MAX_SKB_FRAGS from sysctl knob
  xsk: Bump xsk_queue::queue_empty_descs in xp_can_alloc()
  tcp_bpf: Remove an unused parameter for bpf_tcp_ingress()
  bpf, sockmap: Correct spelling skmsg.c
  netkit: Disable netpoll support
