Merge tag 'net-5.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Networking fixes for 5.11-rc5, including fixes from bpf, wireless, and can trees. Current release - regressions: - nfc: nci: fix the wrong NCI_CORE_INIT parameters Current release - new code bugs: - bpf: allow empty module BTFs Previous releases - regressions: - bpf: fix signed_{sub,add32}_overflows type handling - tcp: do not mess with cloned skbs in tcp_add_backlog() - bpf: prevent double bpf_prog_put call from bpf_tracing_prog_attach - bpf: don't leak memory in bpf getsockopt when optlen == 0 - tcp: fix potential use-after-free due to double kfree() - mac80211: fix encryption issues with WEP - devlink: use right genl user_ptr when handling port param get/set - ipv6: set multicast flag on the multicast route - tcp: fix TCP_USER_TIMEOUT with zero window Previous releases - always broken: - bpf: local storage helpers should check nullness of owner ptr passed - mac80211: fix incorrect strlen of .write in debugfs - cls_flower: call nla_ok() before nla_next() - skbuff: back tiny skbs with kmalloc() in __netdev_alloc_skb() too" * tag 'net-5.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (52 commits) net: systemport: free dev before on error path net: usb: cdc_ncm: don't spew notifications net: mscc: ocelot: Fix multicast to the CPU port tcp: Fix potential use-after-free due to double kfree() bpf: Fix signed_{sub,add32}_overflows type handling can: peak_usb: fix use after free bugs can: vxcan: vxcan_xmit: fix use after free bug can: dev: can_restart: fix use after free bug tcp: fix TCP socket rehash stats mis-accounting net: dsa: b53: fix an off by one in checking "vlan->vid" tcp: do not mess with cloned skbs in tcp_add_backlog() selftests: net: fib_tests: remove duplicate log test net: nfc: nci: fix the wrong NCI_CORE_INIT parameters sh_eth: Fix power down vs. is_opened flag ordering net: Disable NETIF_F_HW_TLS_RX when RXCSUM is disabled netfilter: rpfilter: mask ecn bits before fib lookup udp: mask TOS bits in udp_v4_early_demux() xsk: Clear pool even for inactive queues bpf: Fix helper bpf_map_peek_elem_proto pointing to wrong callback sh_eth: Make PHY access aware of Runtime PM to fix reboot crash ...
