Merge tag 'net-5.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Networking fixes, including fixes from bpf, wireless, netfilter and wireguard trees. The bpf vs lockdown+audit fix is the most notable. Things haven't slowed down just yet, both in terms of regressions in current release and largish fixes for older code, but we usually see a slowdown only after -rc5. Current release - regressions: - virtio-net: fix page faults and crashes when XDP is enabled - mlx5e: fix HW timestamping with CQE compression, and make sure they are only allowed to coexist with capable devices - stmmac: - fix kernel panic due to NULL pointer dereference of mdio_bus_data - fix double clk unprepare when no PHY device is connected Current release - new code bugs: - mt76: a few fixes for the recent MT7921 devices and runtime power management Previous releases - regressions: - ice: - track AF_XDP ZC enabled queues in bitmap to fix copy mode Tx - fix allowing VF to request more/less queues via virtchnl - correct supported and advertised autoneg by using PHY capabilities - allow all LLDP packets from PF to Tx - kbuild: quote OBJCOPY var to avoid a pahole call break the build Previous releases - always broken: - bpf, lockdown, audit: fix buggy SELinux lockdown permission checks - mt76: address the recent FragAttack vulnerabilities not covered by generic fixes - ipv6: fix KASAN: slab-out-of-bounds Read in fib6_nh_flush_exceptions - Bluetooth: - fix the erroneous flush_work() order, to avoid double free - use correct lock to prevent UAF of hdev object - nfc: fix NULL ptr dereference in llcp_sock_getname() after failed connect - ieee802154: multiple fixes to error checking and return values - igb: fix XDP with PTP enabled - intel: add correct exception tracing for XDP - tls: fix use-after-free when TLS offload device goes down and back up - ipvs: ignore IP_VS_SVC_F_HASHED flag when adding service - netfilter: nft_ct: skip expectations for confirmed conntrack - mptcp: fix falling back to TCP in presence of out of order packets early in connection lifetime - wireguard: switch from O(n) to a O(1) algorithm for maintaining peers, fixing stalls and a large memory leak in the process Misc: - devlink: correct VIRTUAL port to not have phys_port attributes - Bluetooth: fix VIRTIO_ID_BT assigned number - net: return the correct errno code ENOBUF -> ENOMEM - wireguard: - peer: allocate in kmem_cache saving 25% on peer memory - do not use -O3" * tag 'net-5.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (91 commits) cxgb4: avoid link re-train during TC-MQPRIO configuration sch_htb: fix refcount leak in htb_parent_to_leaf_offload wireguard: allowedips: free empty intermediate nodes when removing single node wireguard: allowedips: allocate nodes in kmem_cache wireguard: allowedips: remove nodes in O(1) wireguard: allowedips: initialize list head in selftest wireguard: peer: allocate in kmem_cache wireguard: use synchronize_net rather than synchronize_rcu wireguard: do not use -O3 wireguard: selftests: make sure rp_filter is disabled on vethc wireguard: selftests: remove old conntrack kconfig value virtchnl: Add missing padding to virtchnl_proto_hdrs ice: Allow all LLDP packets from PF to Tx ice: report supported and advertised autoneg using PHY capabilities ice: handle the VF VSI rebuild failure ice: Fix VFR issues for AVF drivers that expect ATQLEN cleared ice: Fix allowing VF to request more/less queues via virtchnl virtio-net: fix for skb_over_panic inside big mode ipv6: Fix KASAN: slab-out-of-bounds Read in fib6_nh_flush_exceptions fib: Return the correct errno code ...
