====================
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.
