There were more obfuscation rather than generalisation with this aid. A historical reference on the original idea of the raw sockets can be found in chapter 11 of 4.4BSD System Manager Manual: https://raw.githubusercontent.com/sergev/4.4BSD-Lite2/master/usr/share/doc/smm/18.net.pdf Reviewed by: melifaro Differential revision: https://reviews.freebsd.org/D36124 --- ObsoleteFiles.inc | 3 + sys/conf/files | 2 - sys/net/raw_cb.c | 120 ---------------------- sys/net/raw_cb.h | 90 ----------------- sys/net/raw_usrreq.c | 279 --------------------------------------------------- 5 files changed, 3 insertions(+), 491 deletions(-) diff --git a/ObsoleteFiles.inc b/ObsoleteFiles.inc index a0964243b484..ab55b981106c 100644 --- a/ObsoleteFiles.inc +++ b/ObsoleteFiles.inc @@ -52,6 +52,9 @@ # xargs -n1 | sort | uniq -d; # done +# 202208XX: raw socket layer removed +OLD_FILES+=usr/include/net/raw_cb.h + # 20220721: libnv version bumps OLD_LIBS+=lib/libnv.so.0 diff --git a/sys/conf/files b/sys/conf/files index 9b1ebc85a7ab..faff65dd8426 100644 --- a/sys/conf/files +++ b/sys/conf/files @@ -4164,8 +4164,6 @@ net/debugnet.c optional inet debugnet net/debugnet_inet.c optional inet debugnet net/pfil.c optional ether | inet net/radix.c standard -net/raw_cb.c standard -net/raw_usrreq.c standard net/route.c standard net/route/nhgrp.c optional route_mpath net/route/nhgrp_ctl.c optional route_mpath diff --git a/sys/net/raw_cb.c b/sys/net/raw_cb.c deleted file mode 100644 index 78a117a2c2d8..000000000000 --- a/sys/net/raw_cb.c +++ /dev/null @@ -1,120 +0,0 @@ -/*- - * SPDX-License-Identifier: BSD-3-Clause - * - * Copyright (c) 1980, 1986, 1993 - * The Regents of the University of California. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
