Merge tag 'net-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Networking fixes for 5.13-rc7, including fixes from wireless, bpf, bluetooth, netfilter and can. Current release - regressions: - mlxsw: spectrum_qdisc: Pass handle, not band number to find_class() to fix modifying offloaded qdiscs - lantiq: net: fix duplicated skb in rx descriptor ring - rtnetlink: fix regression in bridge VLAN configuration, empty info is not an error, bot-generated "fix" was not needed - libbpf: s/rx/tx/ typo on umem->rx_ring_setup_done to fix umem creation Current release - new code bugs: - ethtool: fix NULL pointer dereference during module EEPROM dump via the new netlink API - mlx5e: don't update netdev RQs with PTP-RQ, the special purpose queue should not be visible to the stack - mlx5e: select special PTP queue only for SKBTX_HW_TSTAMP skbs - mlx5e: verify dev is present in get devlink port ndo, avoid a panic Previous releases - regressions: - neighbour: allow NUD_NOARP entries to be force GCed - further fixes for fallout from reorg of WiFi locking (staging: rtl8723bs, mac80211, cfg80211) - skbuff: fix incorrect msg_zerocopy copy notifications - mac80211: fix NULL ptr deref for injected rate info - Revert "net/mlx5: Arm only EQs with EQEs" it may cause missed IRQs Previous releases - always broken: - bpf: more speculative execution fixes - netfilter: nft_fib_ipv6: skip ipv6 packets from any to link-local - udp: fix race between close() and udp_abort() resulting in a panic - fix out of bounds when parsing TCP options before packets are validated (in netfilter: synproxy, tc: sch_cake and mptcp) - mptcp: improve operation under memory pressure, add missing wake-ups - mptcp: fix double-lock/soft lookup in subflow_error_report() - bridge: fix races (null pointer deref and UAF) in vlan tunnel egress - ena: fix DMA mapping function issues in XDP - rds: fix memory leak in rds_recvmsg Misc: - vrf: allow larger MTUs - icmp: don't send out ICMP messages with a source address of 0.0.0.0 - cdc_ncm: switch to eth%d interface naming" * tag 'net-5.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (139 commits) net: ethernet: fix potential use-after-free in ec_bhf_remove selftests/net: Add icmp.sh for testing ICMP dummy address responses icmp: don't send out ICMP messages with a source address of 0.0.0.0 net: ll_temac: Avoid ndo_start_xmit returning NETDEV_TX_BUSY net: ll_temac: Fix TX BD buffer overwrite net: ll_temac: Add memory-barriers for TX BD access net: ll_temac: Make sure to free skb when it is completely used MAINTAINERS: add Guvenc as SMC maintainer bnxt_en: Call bnxt_ethtool_free() in bnxt_init_one() error path bnxt_en: Fix TQM fastpath ring backing store computation bnxt_en: Rediscover PHY capabilities after firmware reset cxgb4: fix wrong shift. mac80211: handle various extensible elements correctly mac80211: reset profile_periodicity/ema_ap cfg80211: avoid double free of PMSR request cfg80211: make certificate generation more robust mac80211: minstrel_ht: fix sample time check net: qed: Fix memcpy() overflow of qed_dcbx_params() net: cdc_eem: fix tx fixup skb leak net: hamradio: fix memory leak in mkiss_close ...
