Pull networking fixes from Paolo Abeni: "Including fixes from bpf, netfilter and WiFi. Jakub is doing a lot of work to include the self-tests in our CI, as a result a significant amount of self-tests related fixes is flowing in (and will likely continue in the next few weeks). Current release - regressions: - bpf: fix a kernel crash for the riscv 64 JIT - bnxt_en: fix memory leak in bnxt_hwrm_get_rings() - revert "net: macsec: use skb_ensure_writable_head_tail to expand the skb" Previous releases - regressions: - core: fix removing a namespace with conflicting altnames - tc/flower: fix chain template offload memory leak - tcp: - make sure init the accept_queue's spinlocks once - fix autocork on CPUs with weak memory model - udp: fix busy polling - mlx5e: - fix out-of-bound read in port timestamping - fix peer flow lists corruption - iwlwifi: fix a memory corruption Previous releases - always broken: - netfilter: - nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress basechain - nft_limit: reject configurations that cause integer overflow - bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding a NULL pointer dereference upon shrinking - llc: make llc_ui_sendmsg() more robust against bonding changes - smc: fix illegal rmb_desc access in SMC-D connection dump - dpll: fix pin dump crash for rebound module - bnxt_en: fix possible crash after creating sw mqprio TCs - hv_netvsc: calculate correct ring size when PAGE_SIZE is not 4kB Misc: - several self-tests fixes for better integration with the netdev CI - added several missing modules descriptions" * tag 'net-6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (88 commits) tsnep: Fix XDP_RING_NEED_WAKEUP for empty fill ring tsnep: Remove FCS for XDP data path net: fec: fix the unhandled context fault from smmu selftests: bonding: do not test arp/ns target with mode balance-alb/tlb fjes: fix memleaks in fjes_hw_setup i40e: update xdp_rxq_info::frag_size for ZC enabled Rx queue i40e: set xdp_rxq_info::frag_size xdp: reflect tail increase for MEM_TYPE_XSK_BUFF_POOL ice: update xdp_rxq_info::frag_size for ZC enabled Rx queue intel: xsk: initialize skb_frag_t::bv_offset in ZC drivers ice: remove redundant xdp_rxq_info registration i40e: handle multi-buffer packets that are shrunk by xdp prog ice: work on pre-XDP prog frag count xsk: fix usage of multi-buffer BPF helpers for ZC XDP xsk: make xsk_buff_pool responsible for clearing xdp_buff::flags xsk: recycle buffer in case Rx queue was full net: fill in MODULE_DESCRIPTION()s for rvu_mbox net: fill in MODULE_DESCRIPTION()s for litex net: fill in MODULE_DESCRIPTION()s for fsl_pq_mdio net: fill in MODULE_DESCRIPTION()s for fec ...
