Hi Dave,
both the ipv4 and ipv6 code have an ioctl each that can be used to create
a tunnel using code that doesn't live in the core kernel or ipv6 module.
Currently they call ioctls on the tunnel devices to create these, for
which the code needs to override the address limit, which is a "feature"

Remove the duplicate "mutex", and change "Motex" to "Mutex". Also I
recommend it's easier for understanding to make the "ready-interrupt"

Trivial patch to add get{peer,sock}name cgroup attach types to the BPF
sock_addr programs in order to enable rewriting sockaddr structs from
both calls along with libbpf and bpftool support as well as selftests.
Thanks!
Daniel Borkmann (4):
bpf: add get{peer,sock}name attach types for sock_addr
Trivial patch to add the new get{peer,sock}name attach types to the section
definitions in order to hook them up to sock_addr cgroup program type.

As stated in 983695fa6765 ("bpf: fix unconnected udp hooks"), the objective
for the existing cgroup connect/sendmsg/recvmsg/bind BPF hooks is to be
transparent to applications. In Cilium we make use of these hooks [0] in
order to enable E-W load balancing for existing Kubernetes service types

Make bpftool aware and add the new get{peer,sock}name attach types to its
cli, documentation and bash completion to allow attachment/detachment of

Extend the existing connect_force_port test to assert get{peer,sock}name

as well. The workflow for e.g. IPv4 is as follows: i) server binds to concrete
port, ii) client calls getsockname() on server fd which exposes 1.2.3.4:6 to
client, iii) client connects to service address 1.2.3.4:
