Historically in BSD the raw sockets were not truly raw. The following conventions held:

* packet is modified

Starting with 10.0-RELEASE convention is:

* packet is modified

For longer story see: http://lists.freebsd.org/pipermail/freebsd-current/2014-January/047937.html

We are targeting at 11.0-RELEASE to pass unmodified packets on SOCK_RAW sockets. This was committed as r270929i, new __FreeBSD_version is 1100030.

The minimal set of software in ports that we must adopt by the time patch hits the tree:

port name

status

src/contrib/traceroute

usr.sbin/traceroute/Makefile patch for setting BYTESWAP_IP_HDR (included in the same commit as sock_raw)

net/quagga & net/quagga-re

quagga patch and quagga-re patch (ospf tested on quagga-re) PR 193244

net/zebra

zebra patch (ospf tested) PR 193249

libnet/libdnet

File trunk/config/acinclude.m4 set HAVE_RAWIP_HOST_OFFLEN if OS use host byte ordering: Need to be patched. But I've tested net/dhcprelay (uses libdnet) without patch and it's not impacted

security/ipsec-tools

A port bug (regression since 0.8.1) prevent me to test it (bug related to NAT-T, but even with "nat_traversal off;" in my config file I can't use it)

openvpn

not impacted (tested)

freevrrpd

freevrrpd patch PR 193243

relayd

not impacted (tested)

net/isc-dhcp*-server|relay

isc-dhcp43-relay-4.3.0 and isc-dhcp43-server-4.3.0 not impacted (tested)

bird

ospfv2 (bird) impacted: "Socket error on em0: Invalid argument". Because it works on 10.0 without patching it, it should be a "host byte order" problem and not an "ip_len": sysdep/bsd/sysio.h ? PR 193245

net-snmp

not impacted (tested)

dnsmasq

fping

not impacted (tested)

SOCK_RAW (last edited 2014-09-04 08:08:53 by OlivierCochardLabbé)
