Merge tag 'net-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Networking fixes for 5.13-rc1, including fixes from bpf, can and netfilter trees. Self-contained fixes, nothing risky. Current release - new code bugs: - dsa: ksz: fix a few bugs found by static-checker in the new driver - stmmac: fix frame preemption handshake not triggering after interface restart Previous releases - regressions: - make nla_strcmp handle more then one trailing null character - fix stack OOB reads while fragmenting IPv4 packets in openvswitch and net/sched - sctp: do asoc update earlier in sctp_sf_do_dupcook_a - sctp: delay auto_asconf init until binding the first addr - stmmac: clear receive all(RA) bit when promiscuous mode is off - can: mcp251x: fix resume from sleep before interface was brought up Previous releases - always broken: - bpf: fix leakage of uninitialized bpf stack under speculation - bpf: fix masking negation logic upon negative dst register - netfilter: don't assume that skb_header_pointer() will never fail - only allow init netns to set default tcp cong to a restricted algo - xsk: fix xp_aligned_validate_desc() when len == chunk_size to avoid false positive errors - ethtool: fix missing NLM_F_MULTI flag when dumping - can: m_can: m_can_tx_work_queue(): fix tx_skb race condition - sctp: fix a SCTP_MIB_CURRESTAB leak in sctp_sf_do_dupcook_b - bridge: fix NULL-deref caused by a races between assigning rx_handler_data and setting the IFF_BRIDGE_PORT bit Latecomer: - seg6: add counters support for SRv6 Behaviors" * tag 'net-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (73 commits) atm: firestream: Use fallthrough pseudo-keyword net: stmmac: Do not enable RX FIFO overflow interrupts mptcp: fix splat when closing unaccepted socket i40e: Remove LLDP frame filters i40e: Fix PHY type identifiers for 2.5G and 5G adapters i40e: fix the restart auto-negotiation after FEC modified i40e: Fix use-after-free in i40e_client_subtask() i40e: fix broken XDP support netfilter: nftables: avoid potential overflows on 32bit arches netfilter: nftables: avoid overflows in nft_hash_buckets() tcp: Specify cmsgbuf is user pointer for receive zerocopy. mlxsw: spectrum_mr: Update egress RIF list before route's action net: ipa: fix inter-EE IRQ register definitions can: m_can: m_can_tx_work_queue(): fix tx_skb race condition can: mcp251x: fix resume from sleep before interface was brought up can: mcp251xfd: mcp251xfd_probe(): add missing can_rx_offload_del() in error path can: mcp251xfd: mcp251xfd_probe(): fix an error pointer dereference in probe netfilter: nftables: Fix a memleak from userdata error path in new objects netfilter: remove BUG_ON() after skb_header_pointer() netfilter: nfnetlink_osf: Fix a missing skb_header_pointer() NULL check ...
