Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net-next* tree. We've added 17 non-merge commits during the last 6 day(s) which contain a total of 20 files changed, 1179 insertions(+), 37 deletions(-). The main changes are: 1) Add a BPF hook in sys_socket() to change the protocol ID from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy applications, from Geliang Tang. 2) Follow-up/fallout fix from the SO_REUSEPORT + bpf_sk_assign work to fix a splat on non-fullsock sks in inet[6]_steal_sock, from Lorenz Bauer. 3) Improvements to struct_ops links to avoid forcing presence of update/validate callbacks. Also add bpf_struct_ops fields documentation, from David Vernet. 4) Ensure libbpf sets close-on-exec flag on gzopen, from Marco Vedovati. 5) Several new tcx selftest additions and bpftool link show support for tcx and xdp links, from Daniel Borkmann. 6) Fix a smatch warning on uninitialized symbol in bpf_perf_link_fill_kprobe, from Yafang Shao. 7) BPF selftest fixes e.g. misplaced break in kfunc_call test, from Yipeng Zou. 8) Small cleanup to remove unused declaration bpf_link_new_file, from Yue Haibing. 9) Small typo fix to bpftool's perf help message, from Daniel T. Lee. Please consider pulling these changes from: git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git tags/for-netdev Thanks a lot!
