From ef84703a911f4ee52ca585e8308b7084093941f4 Mon Sep 17 00:00:00 2001 From: Dmitry Safonov Date: Mon, 23 Oct 2023 20:22:10 +0100 Subject: net/tcp: Add TCP-AO getsockopt()s Introduce getsockopt(TCP_AO_GET_KEYS) that lets a user get TCP-AO keys and their properties from a socket. The user can provide a filter to match the specific key to be dumped or ::get_all = 1 may be used to dump all keys in one syscall. Add another getsockopt(TCP_AO_INFO) for providing per-socket/per-ao_info stats: packet counters, Current_key/RNext_key and flags like ::ao_required and ::accept_icmps.
