Merge tag 'net-5.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Including fixes from bpf, netfilter, and ieee802154. Current release - regressions: - Partially revert "net/smc: Add netlink net namespace support", fix uABI breakage - netfilter: - nft_ct: fix use after free when attaching zone template - nft_byteorder: track register operations Previous releases - regressions: - ipheth: fix EOVERFLOW in ipheth_rcvbulk_callback - phy: qca8081: fix speeds lower than 2.5Gb/s - sched: fix use-after-free in tc_new_tfilter() Previous releases - always broken: - tcp: fix mem under-charging with zerocopy sendmsg() - tcp: add missing tcp_skb_can_collapse() test in tcp_shift_skb_data() - neigh: do not trigger immediate probes on NUD_FAILED from neigh_managed_work, avoid a deadlock - bpf: use VM_MAP instead of VM_ALLOC for ringbuf, avoid KASAN false-positives - netfilter: nft_reject_bridge: fix for missing reply from prerouting - smc: forward wakeup to smc socket waitqueue after fallback - ieee802154: - return meaningful error codes from the netlink helpers - mcr20a: fix lifs/sifs periods - at86rf230, ca8210: stop leaking skbs on error paths - macsec: add missing un-offload call for NETDEV_UNREGISTER of parent - ax25: add refcount in ax25_dev to avoid UAF bugs - eth: mlx5e: - fix SFP module EEPROM query - fix broken SKB allocation in HW-GRO - IPsec offload: fix tunnel mode crypto for non-TCP/UDP flows - eth: amd-xgbe: - fix skb data length underflow - ensure reset of the tx_timer_active flag, avoid Tx timeouts - eth: stmmac: fix runtime pm use in stmmac_dvr_remove() - eth: e1000e: handshake with CSME starts from Alder Lake platforms" * tag 'net-5.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (69 commits) ax25: fix reference count leaks of ax25_dev net: stmmac: ensure PTP time register reads are consistent net: ipa: request IPA register values be retained dt-bindings: net: qcom,ipa: add optional qcom,qmp property tools/resolve_btfids: Do not print any commands when building silently bpf: Use VM_MAP instead of VM_ALLOC for ringbuf net, neigh: Do not trigger immediate probes on NUD_FAILED from neigh_managed_work tcp: add missing tcp_skb_can_collapse() test in tcp_shift_skb_data() net: sparx5: do not refer to skb after passing it on Partially revert "net/smc: Add netlink net namespace support" net/mlx5e: Avoid field-overflowing memcpy() net/mlx5e: Use struct_group() for memcpy() region net/mlx5e: Avoid implicit modify hdr for decap drop rule net/mlx5e: IPsec: Fix tunnel mode crypto offload for non TCP/UDP traffic net/mlx5e: IPsec: Fix crypto offload for non TCP/UDP encapsulated traffic net/mlx5e: Don't treat small ceil values as unlimited in HTB offload net/mlx5: E-Switch, Fix uninitialized variable modact net/mlx5e: Fix handling of wrong devices during bond netevent net/mlx5e: Fix broken SKB allocation in HW-GRO net/mlx5e: Fix wrong calculation of header index in HW_GRO ...
