Hello LKFT maintainers, CI operators,
First, I would like to say thank you to the people behind the LKFT
project for validating stable kernels (and more), and including some
Network selftests in their tests suites.
A lot of improvements around the networking kselftests have been done
this year. A

When ro_after_init fails, we need to unload the module.

The KF_TRUSTED_ARGS flag is used for bpf_iter_mptcp_subflow_new, it
indicates that the all pointer arguments are valid. It's necessary to

helpers for this. Increas

MPTCP helper mptcp_sk() is used to convert struct sock to mptcp_sock.

be used in MPTCP BPF programs too.
