.SH DESCRIPTION
|
|
|
|
Linux 2.2 optionally implements the Internet Protocol, version 6.
|
|
|
|
This man page contains a description of the IPv6 basic API as
|
|
|
|
implemented by the Linux kernel and glibc 2.1.
|
|
|
|
The interface
|
|
|
|
is based on the BSD sockets interface; see
|
|
|
|
.BR socket (7).
|
|
|
|
.PP
|
|
|
|
The IPv6 API aims to be mostly compatible with the
|
2008-11-25 23:07:11 +00:00
|
|
|
IPv4 API (see
|
|
|
|
.BR ip (7)).
|
2008-08-08 16:41:48 +00:00
|
|
|
Only differences are described in this man page.
|
|
|
|
.PP
|
|
|
|
To bind an
|
|
|
|
.B AF_INET6
|
2008-11-25 23:07:11 +00:00
|
|
|
socket to any process, the local address should be copied from the
|
2008-08-08 16:41:48 +00:00
|
|
|
.I in6addr_any
|
|
|
|
variable which has
|
|
|
|
.I in6_addr
|
|
|
|
type.
|
2008-11-25 23:07:11 +00:00
|
|
|
In static initializations,
|
2008-08-08 16:41:48 +00:00
|
|
|
.B IN6ADDR_ANY_INIT
|
|
|
|
may also be used, which expands to a constant expression.
|
2008-11-25 23:07:11 +00:00
|
|
|
Both of them are in network byte order.
|
2008-08-08 16:41:48 +00:00
|
|
|
.PP
|
|
|
|
The IPv6 loopback address (::1) is available in the global
|
|
|
|
.I in6addr_loopback
|
|
|
|
variable.
|
2008-11-25 23:07:11 +00:00
|
|
|
For initializations,
|
2008-08-08 16:41:48 +00:00
|
|
|
.B IN6ADDR_LOOPBACK_INIT
|
|
|
|
should be used.
|
|
|
|
.PP
|
|
|
|
IPv4 connections can be handled with the v6 API by using the
|
|
|
|
v4-mapped-on-v6 address type;
|
2008-11-25 23:07:11 +00:00
|
|
|
thus a program only needs to support this API type to
|
2008-08-08 16:41:48 +00:00
|
|
|
support both protocols.
|
|
|
|
This is handled transparently by the address
|
2008-11-25 23:07:11 +00:00
|
|
|
handling functions in the C library.
|
2008-08-08 16:41:48 +00:00
|
|
|
.PP
|
|
|
|
IPv4 and IPv6 share the local port space.
|
|
|
|
When you get an IPv4 connection
|
2008-11-25 23:07:11 +00:00
|
|
|
or packet to a IPv6 socket, its source address will be mapped
|
2008-08-08 16:41:48 +00:00
|
|
|
to v6 and it will be mapped to v6.

Capitalization in .SS sections across pages (and sometimes even
within a single page) is wildly inconsistent. Make it consistent.
Capitalize first word in heading, but otherwise use lower case,
except where English usage (e.g., proper nouns) or programming
language requirements (e.g., identifier names) dictate otherwise.

.SS "Socket options"
|
2008-08-08 16:41:48 +00:00
|
|
|
IPv6 supports some protocol-specific socket options that can be set with
|
|
|
|
.BR setsockopt (2)
|
|
|
|
and read with
|
|
|
|
.BR getsockopt (2).
|
|
|
|
The socket option level for IPv6 is
|
|
|
|
.BR IPPROTO_IPV6 .
|
|
|

A boolean integer flag is zero when it is false, otherwise true.

ipv6.7: Document IPV6_RECVPKTINFO
Notes from Bert Hubert:
Recently PowerDNS needed to support the getting of the
original destination address of packets received on ::.
Following the advice in ipv6(7) generated an error on
setsockopt().
Some googling confirmed that setsockopt() with
IPV6_PKTINFO indeed does not work, but we found that
IPV6_RECVPKTINFO did.
Our experiences are detailed in
http://bert-hubert.blogspot.nl/2012/10/on-binding-datagram-udp-sockets-to-any.html
Please find attached a quite naive patch to ipv6.7 that at
least fixes 'my' problem, but does not document if
IPV6_PKTINFO ever worked as a flag. It does document that
IPV6_RECVPKTINFO is available since 2.6.13.
Please let me know if this patch is acceptable, or if you
want me to dig deeper into the IPV6_PKTINFO situation.
Notes from mtk:
Drop mention of IPV6_PKTINFO; that's IPV6_2292PKTINFO nowadays
(and needs to be documented). And, confusingly, there's nowadays
an IPV6_PKTINFO that is a quite different thig.
With kernel commit 333fad5364d6b457c8d837f7d05802d2aaf8a961
(Sep 2005) PV6_PKTINFO disappeared from the
getsockopt/setsockopt API, and IPV6_2292PKTINFO took its place.
Meanwhile, IPV6_RECVPKTINFO was added.
Then kernel commit b24a2516d10751d7ed5afb58420df25370c9dffb
(Dec 2008) added IPV6_PKTINFO back to the
getsockopt/getsockopt API, but with what looks to be a
rather different meaning (it takes a 'struct in6_pktinfo'
as the third arg).
This seems consistent (if confusing) with the RFCs:
http://www.ietf.org/rfc/rfc2292.txt
http://www.ietf.org/rfc/rfc3542.txt (obsoletes 2292)
Both of those RFCs define an IPV6_PKTINO sockopt, but the
former takes an int arg, and the latter takes a
'struct in6_pktinfo'.
So, my summary of your patch is that it's correct. (But I think
that IPV6_RECVPKTINFO is present since 2.6.14, not 2.6.13.)

.SH NOTES
|
2008-08-08 16:41:48 +00:00
|
|
|
The
|
|
|
|
.I sockaddr_in6
|
|
|
|
structure is bigger than the generic
|
|
|
|
.IR sockaddr .
|
|
|
|
Programs that assume that all address types can be stored safely in a
|
|
|
|
.I struct sockaddr
|
|
|
|
need to be changed to use
|
|
|
|
.I struct sockaddr_storage
|
|
|
|
for that instead.
|
|
|
|
.SH BUGS
|
|
|
|
The IPv6 extended API as in RFC\ 2292 is currently only partly
|
|
|
|
implemented;
|
|
|
|
although the 2.2 kernel has near complete support for receiving options,
|
|
|
|
the macros for generating IPv6 options are missing in glibc 2.1.
|
|
|
|
.PP
|
|
|
|
IPSec support for EH and AH headers is missing.
|
|
|
|
.PP
|
|
|
|
Flow label management is not complete and not documented here.
