Merge tag 'net-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull more networking updates from Jakub Kicinski:
"Networking fixes and rethook patches.
Features:
- kprobes: rethook: x86: replace kretprobe trampoline with rethook
Current release - regressions:
- sfc: avoid null-deref on systems without NUMA awareness in the new
queue sizing code
Current release - new code bugs:
- vxlan: do not feed vxlan_vnifilter_dump_dev with non-vxlan devices
- eth: lan966x: fix null-deref on PHY pointer in timestamp ioctl when
interface is down
Previous releases - always broken:
- openvswitch: correct neighbor discovery target mask field in the
flow dump
- wireguard: ignore v6 endpoints when ipv6 is disabled and fix a leak
- rxrpc: fix call timer start racing with call destruction
- rxrpc: fix null-deref when security type is rxrpc_no_security
- can: fix UAF bugs around echo skbs in multiple drivers
Misc:
- docs: move netdev-FAQ to the 'process' section of the
documentation"
