Merge tag 'net-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Including fixes from netfilter, bpf. Quite a handful of old regression fixes but most of those are pre-5.16. Current release - regressions: - fix memory leaks in the skb free deferral scheme if upper layer protocols are used, i.e. in-kernel TCP readers like TLS Current release - new code bugs: - nf_tables: fix NULL check typo in _clone() functions - change the default to y for Vertexcom vendor Kconfig - a couple of fixes to incorrect uses of ref tracking - two fixes for constifying netdev->dev_addr Previous releases - regressions: - bpf: - various verifier fixes mainly around register offset handling when passed to helper functions - fix mount source displayed for bpffs (none -> bpffs) - bonding: - fix extraction of ports for connection hash calculation - fix bond_xmit_broadcast return value when some devices are down - phy: marvell: add Marvell specific PHY loopback - sch_api: don't skip qdisc attach on ingress, prevent ref leak - htb: restore minimal packet size handling in rate control - sfp: fix high power modules without diagnostic monitoring - mscc: ocelot: - don't let phylink re-enable TX PAUSE on the NPI port - don't dereference NULL pointers with shared tc filters - smsc95xx: correct reset handling for LAN9514 - cpsw: avoid alignment faults by taking NET_IP_ALIGN into account - phy: micrel: use kszphy_suspend/_resume for irq aware devices, avoid races with the interrupt Previous releases - always broken: - xdp: check prog type before updating BPF link - smc: resolve various races around abnormal connection termination - sit: allow encapsulated IPv6 traffic to be delivered locally - axienet: fix init/reset handling, add missing barriers, read the right status words, stop queues correctly - add missing dev_put() in sock_timestamping_bind_phc() Misc: - ipv4: prevent accidentally passing RTO_ONLINK to ip_route_output_key_hash() by sanitizing flags - ipv4: avoid quadratic behavior in netns dismantle - stmmac: dwmac-oxnas: add support for OX810SE - fsl: xgmac_mdio: add workaround for erratum A-009885" * tag 'net-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (92 commits) ipv4: add net_hash_mix() dispersion to fib_info_laddrhash keys ipv4: avoid quadratic behavior in netns dismantle net/fsl: xgmac_mdio: Fix incorrect iounmap when removing module powerpc/fsl/dts: Enable WA for erratum A-009885 on fman3l MDIO buses dt-bindings: net: Document fsl,erratum-a009885 net/fsl: xgmac_mdio: Add workaround for erratum A-009885 net: mscc: ocelot: fix using match before it is set net: phy: micrel: use kszphy_suspend()/kszphy_resume for irq aware devices net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account nfc: llcp: fix NULL error pointer dereference on sendmsg() after failed bind() net: axienet: increase default TX ring size to 128 net: axienet: fix for TX busy handling net: axienet: fix number of TX ring slots for available check net: axienet: Fix TX ring slot available check net: axienet: limit minimum TX ring size net: axienet: add missing memory barriers net: axienet: reset core on initialization prior to MDIO access net: axienet: Wait for PhyRstCmplt after core reset net: axienet: increase reset timeout bpf, selftests: Add ringbuf memory type confusion test ...
