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"
