Subject: pull-request: bpf-next 2024-09-11 From: Daniel Borkmann To: davem@davemloft.net Cc: kuba@kernel.org, pabeni@redhat.com, edumazet@google.com, daniel@iogearbox.net, ast@kernel.org, andrii@kernel.org, martin.lau@linux.dev, netdev@vger.kernel.org, bpf@vger.kernel.org Date: Wed, 11 Sep 2024 23:15:25 +0200 Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net-next* tree. 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 netkit driver, resolve as follows (https://lore.kernel.org/bpf/2444df33-cd03-a929-9ce8-3cf1376d3f78@iogearbox.net): dev->priv_flags |= IFF_LIVE_ADDR_CHANGE; dev->priv_flags |= IFF_PHONY_HEADROOM; dev->priv_flags |= IFF_NO_QUEUE; + dev->priv_flags |= IFF_DISABLE_NETPOLL; + dev->lltx = true; dev->ethtool_ops = &netkit_ethtool_ops; dev->netdev_ops = &netkit_netdev_ops; 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.
