CHANGELOG for KAME kit

$Id: CHANGELOG,v 1.629 2000/02/28 00:53:48 itojun Exp $

<200002>
Sun Feb 27 18:27:51 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_init.c: allow extended scoped IPv6 address format
into "nameserver" line in /etc/resolv.conf.

Sun Feb 27 17:49:32 JST 2000 itojun@iijlab.net
* {netbsd,openbsd}/lib/libinet6/getaddrinfo.c: add OS-specific
getaddrinfo, which keeps search order declared in /etc/nsswitch.conf
or /etc/resolv.conf.

Sun Feb 27 16:43:04 JST 2000 itojun@iijlab.net
* */sys/sys/socket.h: use ALIGNBYTES, instead of sizeof(long) - 1,
for CMSG alignment. without it CMSG alignment is not spec
conformant if
ALIGNBYTES > sizeof(long) - 1.
this add dependency from sys/socket.h to machine/param.h - which may
not be right.

NOTE: recompile all IPv6 userland, if you are on architecture
with ALIGNBYTES != sizeof(long) - 1.
TODO: make it future adaptable by using sysctl hw.alignbytes.
(maybe for *bsd-current?)

Sat Feb 26 20:46:03 JST 2000 itojun@iijlab.net
* sys/netinet6/esp_input.c: with IPv6 ESP, correctly handle
off != sizeof(ip6) case.
* sys/netinet6/ah_input.c: with IPv4 AH (m_pulldown case),
strip off AH from the packet. this is to make some of IPv4
transport layer code work correctly (specifically, ICMPv4 will
transmit wrong packet if we don't strip AH here)

2000-02-26 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/netinet/tcp_input.c (tcp_input): made the variable
"ip" consistent with "ip6" in order to avoid possible pointer
mismatches.

2000-02-26 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet/in_gif.c (in_gif_ioctl):
* kame/sys/netinet6/in6_gif.c (in6_gif_ioctl):
- prevented in[6]_gif_ioctl from making dangling pointers after
freeing old ones. Without this fix, kernel would panic when we
tried to gifconfig multiple times on a single gif.
- call encap_detach before encap_attach().
If detach was called after attach, we'd not be able to delete
an existing pair of phyaddrs.

2000-02-26 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi[34]/sys/netinet/in.c (in_control): called gif_ioctl() for
gif related ioctls. We need this for initializing encapsulation
switch.

2000-02-26 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sbin/ifconfig/ifconfig.c: filled a valid pointer in
af_stab[MASK] of the afswitch structure for IPv6.
Disabled inet6_auto(), since KAME assigns a link-local address in
the kernel.

2000-02-26 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/v6test/getconfig.c (make_ip6): made ipv6 version and
traffic class fields configurable.
* kame/kame/v6test/conf/ext.conf: added new tests "badver" and
"tclass" to aset non-default values to version and traffic class
fields, respectively.

Sat Feb 26 03:03:21 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/security/heimdal: upgrade to 0.2q.
* openbsd: sys tree was broken for 4 days since "m->m_pkthdr.aux"
change. sorry for this. now we properly initialize aux pointer
and the kernel boots fine.

Fri Feb 25 18:03:58 JST 2000 itojun@iijlab.net
* kame/traceroute/ifaddrlist.c: ignore 0.0.0.0, it is meaningless
as source. if you run ISC DHCP client and lease expires, the address
appears as interface address.

2000-02-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/net/if.c (ifa_ifwithnet):
* bsdi4/sys/net/route.c (ifa_ifwithroute):
loosened restriction on p2p interfaces. It was too strict for
KAME's IPv6 support.

2000-02-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {(net|open)bsd, freebsd3}/sys/netinet/tcp_input.c:
* kame/sys/netinet6/tcp6_input.c:
prevented from storing 2292bis IPv6 options in a listening
socket. Ancillary data on a listening socket was meaningless and
even harmful for applications.

2000-02-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
RFC2292bis support:
* bsdi4/sys/netinet/tcp_output.c (tcp_output):
passed IPv6 output options to ip6_ouput().
* bsdi4/sys/netinet/tcp_input.c:
passed specified IPv6 optional data to a user as ancillary data.
* bsdi4/sys/netinet/in_pcb.c (in_pcbdetach):
fixed memory leak of received IPv6 options.

2000-02-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/libinet6/getnameinfo.c (ip6_sa2str, getnameinfo):
changes according to the recent discussion:
- always print scope_id of an IPv6 address with non-zero
sin6_scope_id (by default), even for a global unicast address.
- use numeric numbers as the last resort of a scope_id string.

Fri Feb 25 01:49:00 JST 2000 itojun@iijlab.net
* */sys/net/rtsock.c: wrap BBN hack (honor ifp/ifa on RTM_ADD),
into #ifdef BBNHACK. it conflicts with proxy NDP and mobile-ip6.
(see CHANGELOG entry on Tue Nov 17 14:57:51)

Fri Feb 25 01:34:11 JST 2000 itojun@iijlab.net
* sys/netinet6/in6.c: net.inet6.icmp6.nd6_proxyall was obsoleted.
use "ndp -s <v6> <mac> proxy" if you need the same functionality.

Fri Feb 25 01:34:37 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd2/ports/openssh: make buildable.
* freebsd3/ports/heimdal: upgrade to 0.2q.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/usr.sbin/{traceroute6, ping6}/Makefile: enabled IPsec
related definitions.

Thu Feb 24 18:59:14 JST 2000 itojun@iijlab.net
* sys/netinet/ip_icmp.c (except openbsd):
don't transmit ICMPv4 packet back if the original packet was
encrypted. if we send those, we may mistakingly leak secret
information. From: jinmei

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/usr.sbin/vmstat: was just imported. We don't have to
modify the code, but it should be recompiled to support additional
memory types used in the kernel.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_control): clarified address
management ioctls:
- invalidated SIOCSIFDSTADDR_IN6 and SIOCSIFNETMASK_IN6. They are
not very suitable in an IPv6 era, when we can assign multiple
addresses on a single interface.
- added strict validations for address families of arguments.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/usr.sbin/netstat/{main.c, inet6.c(added)}: printed KAME's
statistics for IPv6 and ICMPv6 instead of original ones.

Thu Feb 24 JST 2000 itojun@iijlab.net
* libinet6/getifaddrs.c: bring in freeifaddrs(). this is in sync
with bsdi4 change. From: dab@bsdi.com
* bsdi4: enable kernel IPsec code by default. it looks to be working
fine now, thanks to jinmei's efforts.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ah_input.c (ah4_input): prevented
re-translating the byte order of the ip_id field on bsdi4.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/netstat/ipsec.c:
* bsdi4/usr.sbin/netstat:
modified to print KAME's IPsec statistics.

2000-02-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/traceroute/traceroute.c (send_probe):
* bsdi4/usr.sbin/traceroute/Makefile:
changed a bit to calculate a UDP checksum correctly on bsdi4.

Wed Feb 23 21:26:21 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
fixed to compute RSA signature. SIGN was computed including OID.
Now, racoon gets a interoperability with isakmp-test.ssh.fi.
TODO: must be check the signer of certificate.

2000-02-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* (all OSes)/usr.sbin/{bgpd, pim6[ds]d}/Makefile: added the
-DHAVE_GETIFADDRS compile option.
Note: please be sure to update the whole tree, do "make prepare",
update include files, and then rebuild the whole kit.

2000-02-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6[ds]d/config.c (config_vifs_from_kernel): used
getifaddrs().

2000-02-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.pco.jp>
* kame/kame/bgpd/if.c (ifconfig): use getifaddrs (if available)
instead of SIOCGIFCONF, since the former interface is more
friendly and safer.

Wed Feb 23 JST 2000 itojun@iijlab.net
* libinet6/getifaddrs.c: bring in getifaddrs(3) from BSDI4 (it is
under redistributable Berkeley license). SIOCGIFCONF is very hard to
use correctly, due to (1) alignment constraints in 64bit arch
(2) try-and-error memory allocation since there's no way to estimate
required buffer size beforehand. We hope to bring this function
into *BSD.

* freebsd2/ports/openssh: upgrade to 1.2.2 and mark as broken. we
need volunteers to make buildable this port.

Tue Feb 22 00:59:54 JST 2000 itojun@iijlab.net
* sys/kern/uipc_mbuf{,2}.c, sys/sys/mbuf.h: allow mbuf attachment to
m->m_pkthdr.aux. this would be useful to pass around extra
information across protocol handlers. current consumers are
sys/netinet/ip_encap.c (extra data passing - mainly for struct ifnet)
and sys/netinet6/ipsec.c (socket policy passing).
careful about mbuf memory leak if you try using it...

NOTE: it is necessary to clear m_pkthdr on mbuf allocation.
there are drivers that does NOT use MGETHDR to allocate packet
header mbuf. these drivers may need fixes.

2000-02-21 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/(several files): added initialization for IPsec. Now
the kernel can be built and run with the IPSEC option (though we
may need some more work to stabilize it).

Mon Feb 21 20:48:13 JST 2000 itojun@iijlab.net
* {freebsd[23],netbsd}/usr.sbin/racoon/Makefile.inc:

bsdi3/sys/net/. The kernel will be able to be built with the IPSEC
option with these files, but we've not fully tested the KAME IPsec
stuff on bsdi4. Please do not try it for now.

2000-02-21 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>

Sat Feb 19 11:40:58 2000 Shin'ichi Fujisawa <fujisawa@kame.net>
* sys/netinet6/natpt*: Now, this translator can handle connection from
outside v4 (global) to inside v6 (private). This translation is
done when packet is coming toward particular address and port, so
you must know this particular port number before making connection.

- kernel:
many changes in netinet6/natpt_*.[ch]
add in4_len2mask() in netinet/in.c to call in_len2mask().

- userland:
slightly changed natptconfig command syntax.

Thu Feb 17 14:36:07 JST 2000 itojun@iijlab.net
* sys/netinet6/nd6.c: better support for proxy NDP (per ND entry,
just like arp -s). routing entry marked with RTF_ANNONUCE
(= RTF_PROTO2) will get announced by proxy ND. on ND table, proxy
NDP entry will stay as permanent/reachable entry.

To use this stuff, you need to backout bbn changes in rtsock.c.
otherwise ndp -s will not work and you can not set proxy ND entry.
(bbn rt_setif() overwrites sockaddr_dl in gateway portion)

TODO:
- proxy NA delay on output (RFC2461 7.2.8)
- anycast NA delay on output (RFC2461 7.2.7)
* */usr.sbin/ndp: proxy ND support (ndp -s has "proxy" keyword added).

TODO: proxy ND for global address X, where X is outside of prefixes
assigned to the interface we would do proxy ND. currently we try to
grab link-layer information from RTM_GET. so if X is outside of
configured prefixes, we can't configure X for proxy NDing, or static
ND entry. we may need to explicitly pass "interface" information
to ndp -s.

Thu Feb 17 00:40:39 JST 2000 itojun@iijlab.net
* sys/net/if_gif.c: fix IFF_LINK0 (multi destination mode), which

getaddrinfo(AI_ADDRCONFIG). the semantics of AI_ADDRCONFIG is
still very vague so do not expect stable behavior.

2000-02-15 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4, openbsd}/sys/netinet6/raw_ipv6.c (rip6_ctloutput):

NetBSD PR9387 from nrt@iij.ad.jp.

Fri Feb 11 02:42:16 JST 2000 itojun@iijlab.net
* sys/netinet/ip_encap.c: revisit input logic for tunnelled packets.
move outer address match logic from in{,6}_gif_input() to
encap[46]_input(), so that other guys (like mobile-ip6, 6to4,
6over4, whatever) can match packets based on not only by proto #,
but also by src/dst with masks.
see comment on ip_encap.c for detail - I hate tunnelling. really.
TODO: we do not really support subnet match for input logic. it
needs careful ordering of packet matching table in encap[46],
so that we can check for better match earlier.
(since we have mask parameter for both src and dst, it is
not trivial to define total order among entries)
TODO: change ipip_input() to conform to this framework?
CAVEAT: IFF_LINK0 for gif is not working with this change, i'll try
to clean it up.
* allow raw ip{,6} output for proto #4 and #41.

Fri Feb 11 01:48:16 JST 2000 itojun@iijlab.net
* sys/netinet6/raw_ip6.c: implement rip6_ctlinput(), so that we can
notify of route changes to raw ip6 layer (not ready for

* kame/sys/netinet6/ipsec.c (and other ipsec items):
cleanup include file dependencies and namespace polution, like
prototypes and #define KERNEL.
* kame/sys/netinet6/ip6_input.c: fix ip6_savecontrol() to be friendly
with m_pulldown() environment. now it does not modify mbuf chain
at all. therefore, calling ip6_savecontrol() will not invalidate
pointers into mbuf chain (like "uh" in udp6_input).

socket.

2000-01-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/advapitest: was added mainly for debugging. The tools

2000-01-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6_pcb.h (and many related places):
changed the type of the in6p_inputopts member of the in[6]pcb

binary compatibility issues.
I believe this fix solves all the recent problem reports due to
the member.
It is recommended to recompile both the kernel and all the
userland applications with this fix.

update ALTQ from 2.0 to 2.1.
this version supports openbsd in addition to freebsd2, freebsd3
and netbsd.
kernel:
- altq related files are moved from "sys/net" and "sys/netinet"
to "sys/altq" not to bloat the standard directories.
- rename the altq kernel config file from ALTQ to ALTQ.v4 since
it's only for IPv4 and GENERIC.v6 has ALTQ already defined.
for openbsd/netbsd, on non-i386 architecture: read IMPLEMENTATION
section 5 for installation details.
userland:
- the following altq tools are added to the tree:
lib/altqlib, usr.sbin/altqd, user.bin/altqstat.
- install MAKEDEV.altq to /dev.

NOTE: be sure to cleanup old symlinks, by "make TARGET=netbsd clean",
in the top directory.

2000-01-14 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_copypktopts): was added in
order to copy the in6p_outputopts member from a listening PCB to a
corresponding accepting one. TCP input routines are also modified
to call the function.

2000-01-14 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_input.c (ip6_savecontrol): was modified in
order to conform to Section 4.1 of rfc2292bis-01; TCP
implementation now passes incoming packet infomration to a user
(as ancillary data) only when some changes of the content exist.
Note that this change introduced various related changes of
transport layers on all the platforms. Please be careful updating.

2000-01-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd[23]/sbin/route/route.c (getaddr): corrected a bug in
examining interface flags for the RTA_GATEWAY case in getaddr();
use a separate variable and ioctl in order to get correct flags.
Note that this fix may introduce a stricter check for arguments of
the `-interface' modifiers; now you can specify point-to-pointer
interfaces only, which was the intention of the code.

2000-01-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi3/sbin/route/route.c (getaddr): reverted the change for the
"-interface XXX" modifier. We can use the -ifp modifier to
accomplish the motivation.

2000-01-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/{in6.h, ip6_output}: disabled the following
socket options, that were just derived from IPv4 and were not
standards any more;
IPV6_OPTIONS, IPV6_RECVOPTS, IPV6_RECVRETOPTS, IPV6_RECVDSTADDR,
and IPV6_RETOPTS.

2000-01-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/net/if_gif.c (gif_output): changed the (default) upper
limit of how many times gif_output can be called.
Now no nesting is allowed by default, since some systems do not
allow so many recursive calls in kernel.

Sun Jan 9 10:32:59 JST 2000 sakane@kame.net
massive clarification to racoon ISAKMP daemon.
- Merged Eric Lemiere's code for limited certificate support.
- There are two management hander.
"Phase 1 handler" is to manage ISAKMP SA. It is created when
phase 1 exchange on both initiator and responder side will be
started.
"Phase 2 handler" is to manage IPsec SAs. It is created when
pfkey acquire message will be received, and when 1st message
in phase 2 will be received on responder side.
- Vendor id will be sent after negotiating hasn algorithm.
When we receive vendor id before negotiating it, we use default hash
algorithm MD5 to check.
- Post command deleted.
- msgid_t delted.
- don't release management handler. do it only if retry will be
timed up.
- separate the function of isakmp exchange. one is to check received
data. other is to reply. the reason is for handling to resend.
- change name "dir" to "side" in order to distinguish from policy
direction.
- If initiator request PFS, but responder is not ready to do that,
responder stops the negotiation. If initiator don't request PFS,
but responder require it, also responder stops the negotiation.

* /sys/netinet/udp_usrreq.c, kame/sys/netinet6/udp6_usrreq.c:
drop incoming udp packet with dst port = 0. it is, or seems to be,
illegal based on RFC768 (99% sure but 1% in doubt).
with traditional 4.4BSD code, udp socket will mistakingly accept
such packets after socket() and before first bind()/connect().
this can be used to confuse, or de-synchronize, udp-based protocols.

command and natpt related commands.

- These NAT-PT translator and commands are now under development.
Its user interface and overall functionality are subject to
future improvements and changes. So, please be careful when you
try it.

- At this time, this translator works on FreeBSD228 only. Please
wait a while to works on other platforms.

Sat Jan 8 00:09:44 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>

neccesary anymore.

2000-01-07 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_output): do not insert a
dest options header (even if specified by a user) that should be
placed before a routing header, unless a routing header really
exists.

2000-01-07 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/rtsold: use raw ip6 socket for probing interface
status instead of a separate UDP socket, in order to avoid
receiving unexpected UDP datagrams.
In response to: kit/187

2000-01-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/icmp6.c (icmp6_input): upper layer detection
in notifying an icmp6 error was improved:
- if the erroneous packet contains a routing header, examine the
header to determine the final destination and use it to update
path MTU.
- if the erroneous packet contains a fragment header, stop
chasing the header chain unless it is the first fragment.

With the former fix the kernel will perform path MTU discovery
correctly even if triggered packets contain a routing header.

* A new function icmp6_mtudisc_update() was added to cleanup the
code.

Thu Jan 6 16:43:52 JST 2000 itojun@iijlab.net
* sys/netkey/key.c: when searching IPsec SA for inbound IPsec traffic,
do not check src match according to RFC2401. it looks that IPsec
specs do not really agree with each other about what should be
in IPsec SA, and what should be matched. see comment lines near
key_allocsa().

Thu Jan 6 13:49:43 JST 2000 itojun@iijlab.net

Wed Jan 5 19:44:12 JST 2000 itojun@iijlab.net
* netbsd/usr.bin/systat, openbsd/usr.bin/systat:
make systat IPv6 ready. "netstat" subcommand is changed for this.

Wed Jan 5 13:27:43 JST 2000 itojun@iijlab.net
* kame/libinet6/getnameinfo.c: allow reverse lookup for v4 loopback
network (127.0.0.0/8).
* kame/libinet6/rcmd.c: implement iruserok_sa(). iruserok_af() does
not make sense as it is not scope-aware.
nuke ruserok_af(), as ruserok() takes string hostname and is af
independent already. we don't really need ruserok_af().
iruserok_af() is kept for backward compatibility. we'll nuke it
afterwards.

Wed Jan 5 02:49:05 JST 2000 itojun@iijlab.net
* netbsd: add net.inet6.ip6.bindv6only sysctl. this is a replacement
of net.inet6.ip6.mapped_addr, which was bitwise opposite to
IPV6_BINDV6ONLY.
if set to 1: AF_INET6 listening socket will grab IPv6 traffic only.
if set to 0: AF_INET6 listening socket will grab IPv4 traffic as well,
as if it was from v4 mapped address (described in rfc1933).
default value is 1 (i.e. AF_INET6 socket grabs IPv6 traffic only).
the variable controls inbound direction only; you can always use
v4 mapped address for outgoing connections.

"options INET6_BINDV6ONLY" will remove the code completely and
hardcodes behavior to net.inet6.ip6.bindv6only=1 case.

"options MAPPED_ADDR_ENABLED" and net.inet6.ip6.mapped_addr were
obsoleted on netbsd (were introduced on Dec 21 1999).

2000-01-05 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/{bgpd, pim6[ds]d, ping6, traceroute6}: were modified
to use rfc2292bis by default. Related Makefiles were also
modified.

2000-01-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/libinet6/{ip6opt.c, rthdr.c}: implemented some new
functions introduced in rfc2292bis (see TODO.2292bis for more
details).
All the new functions except rcmd_af and rexec_af are now
available.

2000-01-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/{various files}: implemented the new advanced
API (rfc2292bis). The kernel part is now almost finished (see
TODO.2292bis for more details).

Note about lower compatibility: I believe the new kernel is
fairly compatible with the old API (i.e. RFC2292).

There are few compatibility issues in interfaces using ancillary
data. I believe the compatibility issues won't practically bother
you.

You don't have to care compatibility when setting a socket option
except IPV6_HOPLIMIT. If you use the option but don't want to
migrate to the new API, you have two choices. One is to use
IPV6_RECVHOPLIMIT instead of IPV6_HOPLIMIT and just keep the other
code. The other is to define COMPAT_RFC2292 in your kernel
configuration file and recompile the kernel. Then the kernel will
handle IPV6_HOPLIMIT in the RFC2292 manner.

Unfortunately, it is impossible to ensure compatibility for
getting socket options whose semantics in the new API is different
than in RFC2292. If you don't want to use the new API but want to
do getsockopt for such options (I believe the possibility is very
rare, though) define COMPAT_RFC2292 in your kernel configuration
file and recompile the kernel. Then the kernel will handle the
options in the RFC2292 manner.

Please note that the new API is enabled by default in any case.

Tue Jan 4 18:59:08 JST 2000 sakane@ydc.co.jp
