Breno Leitao 09fba0162b bpf: Add sockptr support for setsockopt ... [ Upstream commit 3f31e0d14d ] The whole network stack uses sockptr, and while it doesn't move to something more modern, let's use sockptr in setsockptr BPF hooks, so, it could be used by other callers. The main motivation for this change is to use it in the io_uring {g,s}etsockopt(), which will use a userspace pointer for *optval, but, a kernel value for optlen.
