CHANGELOG for KAME kit

$KAME: CHANGELOG,v 1.1166 2000/07/29 23:33:26 jinmei Exp $

<200007>
2000-07-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/(various files): made FAKE_LOOPBACK_IF default
(as previously announced). At this moment, the older behavior can
be specified by the "OLD_LOOPBACK_IF" kernel compilation option.

2000-07-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6_rtr.c: made ND6_USE_RTSOCK option default.

2000-07-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6sd/vif.c (init_vifs):
* kame/kame/pim6sd/cfparse.y (phyint_config):
made sure to check if a valid global address exists after parsing
the configuration file, in order to avoid unexpected hang up.
From: Kengo NAGAHASHI <kenken@wide.ad.jp>

Sat Jul 29 JST 2000 itojun@iijlab.net
* freebsd2/bsdi3: repair NEW_STRUCT_ROUTE support.

Sat Jul 29 07:57:41 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/{libpcap,tcpdump}: use 2000/7/24 weekly snap
from tcpdump.org.

Fri 28 Jul 18:56:23 JST 2000 kjc@csl.sony.co.jp
* make altqd aware of token bucket regulators
- install a token bucket regulator when an interface is
attached unless there is already one installed.
- remove the installed tbr when the interface is detached.

Fri Jul 28 12:46:55 JST 2000 itojun@iijlab.net
* netbsd/sys/netinet/tcp_output.c: add missing call to tcp6_quench().
* GENERIC.v6 config file for all *BSD:
enable NEW_STRUCT_ROUTE and FAKE_LOOPBACK_IF for torture-testing,
which will be enabled by default soon.

Thu Jul 27 22:40:51 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_forward.c: do not forward packets with unspecified
IPv6 source. this is not on the documents, but it seems to have got
rough consensus on ipngwg (July 2000).

Thu Jul 27 12:16:52 JST 2000 itojun@iijlab.net
* tcp6 layer (all *BSD):
be proactive about unspecified IPv6 source address. pcb layer uses
unspecified address (::) to mean "unbounded" or "unconnected",
and can be confused by packets from outside.

Wed Jul 26 JST 2000 itojun@iijlab.net
* sys/netinet6: repair faith support. there are couple of mistakes
we had: (1) m->m_pkthdr.rcvif no longer points to faith* interface,
however, tcp/udp/icmp6 layer tried to check rcvif. this results in
mysterious icmp6 reply from faith relaying node, for translated
destinations. (2) in many places "faith.h" was not included

Wed 26 Jul 19:55:19 JST 2000 kjc@csl.sony.co.jp
* add tbrconfig(8), a tool to configure a token bucket regulator
for an interface.
(need ALTQ configured in the kernel. A SMP box should have
ALTQ_NOPCC not to use processor cycle counter)
tbrconfig(8) is originally written for tuning ALTQ, but
can be used as a handy tool to rate-limit an interface.
for example, to rate-limit the fxp0 interface up to 25Mbps,
# tbrconfig fxp0 25M auto
see tbrconfig(8) for more details.

Wed Jul 26 12:52:50 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
Fixed to get a destination address when a packet is received from
a peer. It happened when a interface had similar multiple addresses.

Wed Jul 26 11:08:23 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_input.c: reject IPv6 packet with IPv4 mapped
address in the header. this makes more sense as we cannot be
put into SIIT environment (no BSD supports non-INET kernel
compilation). This is an undo for a change on Mar 28 2000.

Wed Jul 26 11:01:41 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 2000/7/24 weekly snap
from tcpdump.org.

2000-07-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/usr.bin/telnet/commands.c (tn): set the source address
specfied by the -s option correctly.
KAME PR sys/272.

Tue 25 Jul 19:12:42 JST 2000 kjc@csl.sony.co.jp
* the first round of ALTQ interface mega cleanup:
- cleanup the system interface to the rest of the kernel.
(the second round cleans up altq internals.)
* bring in the new output queue model.
the new model removes "#ifdef ALTQ" from most of the
drivers, and thus, touches all the drivers used by ALTQ.
- the type of if_snd in struct ifnet is changed from
struct ifqueue to struct ifaltq.
- the altq related fields are moved from struct ifnet
to struct ifaltq.
- use the newly introduced IFQ_XXX macros instead of
IF_XXX macros
* the new altq mechanism consists of classifier, queueing
discipline, and token bucket regulator.
- add token bucket regulator to control network devices.
tbr decouples driver tuning from disciplines.
* other changes:
- removed 2 kernel config options
ALTQ_ACCOUNT: should be part of classifier
AFMAP: doesn't really belong to altq
- added kernel option
ALTQ_NOPPC: do not use processor cycle counter
- support alpha architecture on netbsd/openbsd.
make use of alpha_rpcc() for a high resolution clock.
- add new driver support: ex, wi, tun, ppp
- some other style(9) cleanup

Mon Jul 24 23:34:26 JST 2000 itojun@iijlab.net
* *bsd*/usr.bin/telnet/commands.c: do not use IPV6_PKTOPTIONS in
2292bis API environment. IPv6 source route is temporarily disabled.
* libinet6/if_nameindex.c: malloc length computation bug. from kjc.

Mon Jul 24 09:31:25 JST 2000 itojun@iijlab.net
* sys/netinet6/in6.h: try to provide binary backward compatibility for
RFC2292 API, deployed into freebsd40/netbsd15/openbsd27.
PLEASE RECOMPILE ALL KAME USERLAND BINARIES.

Mon Jul 24 08:22:29 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/netperf: use the latest IPv6 patch (7/21).

Sat Jul 22 01:05:03 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
Trying to conform with draft-ietf-mobileip-ipv6-12. If "support_mip6"
in remote directive is on, both values of ID payloads in phase 2
exchange are always used as the addresses of end-point of IPsec-SAs.

Sat Jul 22 JST 2000 itojun@iijlab.net
* sys/netinet6/esp_core.c: cache intermediate key for ESP encryption
algorithms, into SAs. this will drastically improve performance
for algorithms with long key setup time (blowfish).
KAME PR 229. suggested by sommerfeld.

Fri Jul 21 22:37:44 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/mail/sendmail.beta: use 8.11.0.
* netbsd/pkgsrc/net/netperf: use the latest IPv6 patch (7/21).

2000-07-21 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/bgpd/bgp.c: clarification about the advanced API;
do not use IPV6_PKTOPTIONS in pure RFC2292 (i.e. not 2292bis)
paths.

Thu Jul 20 01:52:59 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/{libpcap,tcpdump}: use 7/17 weekly snap.
* freebsd3/ports/mtr: use latest IPv6 patch.

Wed Jul 19 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- when racoon is running local test mode, AND initial contact is
received, don't delete phase 2 SA.
- more improve to delete phase 1 SA on receiving initial contact.

Wed Jul 19 22:22:47 JST 2000 itojun@iiljab.net
* kame/rtsold/rtsol.c, kame/rtadvd/rtadvd.c: ip6_var.h requires
sys/queue.h.
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 7/17 weekly snap.

Tue Jul 18 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- don't send notify message in processing of information exchange.
- fixed a possible memory leak when error occure.
- added some message about comparing each values in proposal.
- improved to delete phase1 SA when delete message is received OR
initial contact is received.

Mon Jul 17 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- commented when id payload of subnet type with full bit masked.

Mon Jul 17 18:45:11 JST 2000 itojun@iijlab.net
* sys/netkey/key.c: allow ESP with no authentication. it was
mistakenly forbidden with the recent key.c change.

Mon Jul 17 03:31:47 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/ruby: upgrade to 1.4.5.

Sun Jul 16 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- commented when id payload of subnet type with full bit masked.
- racoon.conf are updated about padding option.

Sun Jul 16 16:44:24 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_forward.c: enable IPSEC_IPV6FWD case by default.
(actually, previous default behavior was wrong as it transmits
forwarded packets in clear, even though the policy asks for
encryption)

Sun Jul 16 14:32:58 JST 2000 itojun@iijlab.net
* kame/ping6:
- check duplicated replies for node information query (*)
- fill nonce field for node information query (*)
- use generic icmp6 printer for echo/echo reply/ni reply/ni reply,
when ident/nonce does not match
- clarlify outgoing packet construction a bit
(*) based on patch from yoshfuji, cleaned up by itojun

Sun Jul 16 13:26:12 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: ICMPv6 node information query now based on
06 draft (ping6 -w).

Sun Jul 16 00:57:23 JST 2000 itojun@iijlab.net
* sys/netinet6/in6.h; do not pull sys/queue.h in (it is not
necessary anyways)
* sys/net/pfkeyv2.h: correct conformance to RFC2367 (SADB_[EA]ALG_xx
symbol name). beware: the change breaks backward compatibility.
setkey and racoon MUST be recompiled after updating include files.

Sat Jul 15 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- fixed the place of checking whether delete payload is protected
when delete notification is received.
- When a IKE node receive a delete payload, the node always delete
outbount SAs only. So destination IP address have to check before
SA will be deleted.
- Delete phase 1 handler when a delete notification has been received.
Renamed purge_spi() to purge_ipsec_spi() accompanied with above
chanege.
- commented about the reason why we don't send delete payload
for outbound SAs.
- added a option to randomize values in a padding. clarified to
randomize length.
- fixed some of memory leak.

Sat Jul 15 13:51:59 JST 2000 itojun@iijlab.net
* kame/route6d: if a routing entry exists for aggregate prefix (-A),
do not overwrite it (exit with error). it should be a safer behavir.

Fri Jul 14 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- enable to switch sending initial contact.
- try to send delete payload on phase 1 when phase 1 sa is deleted
- fixed to compare address family in two sockaddrs.
- fixed making a length of IPv6 ID payload. it was used a length of
struct in_addr.
- fixed a part of sending a notification on phase 2.
- fixed making a ID payload of type of IPv4 address. There was
unnecessary space in a address part.

Thu Jul 13 22:27:18 JST 2000 itojun@iijlab.net
* openbsd/sys/netinet6/raw_ipv6.c: enable IPv6 multicast routing
related setsockopt.
* kame/sys/netinet6/ip6_mroute.c: to enable openbsd users to perform
netstat -g, make mif6table a non-static variable. on openbsd
file static variables will not appear in kernel symbol table.

Thu Jul 13 16:09:57 JST 2000 itojun@iiljab.net
* netbsd/pkgsrc/net/bind9: upgrade to 9.0.0rc1.

Thu Jul 13 01:39:26 JST 2000 itojun@iijlab.net
* sys/kern/uipc_mbuf2.c: cleanup m_pulldown statistics.
(1) PULLDOWN_STAT is now a global compilation option (should be
put into kernel configuration file). (2) m_pulldown statistics
now belong to mbstat, and available via netstat -m (instead of
netstat -sn -f inet6). suggested by jinmei.

2000-07-12 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* *bsd*/sys/net/route.h: redefined the route structure so that it
can support protcols that have large socket address (e.g. IPv6).
Currently, this is enabled only with the NEW_STRUCT_ROUTE kernel
compilation option, but will be default once stabilized.
* many files mainly under the netinet and netinet6 directories
were also modified with this change.

2000-07-12 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_ifloop_request):
do not force rtrequest() to return an rtentry when executing the
DELETE operation, in order to avoid overdecreasing the refcnt.
Older versions might cause leak of rtentry when you delete an IPv6
address (via ifconfig, ndp -P, or something).
Fortunately, address deletion is not issued so often, the bug is
effectively not very serious. However, if you have chance to
update your kernel, it is of course recommended to apply this fix.
In particular, KAME's dtcp or ppp (for IPv6) users are highly
recommended to upgrade the kernel.

2000-07-11 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6.h: commented out the definition of
ND6_LLINFO_WAITDELETE, which is not used any more.
* kame/sys/netinet6/nd6.c:
* kame/sys/netinet6/mip6_md.c:
* kame/kame/ndp/ndp.c:
removed ND6_LLINFO_WAITDELETE cases according to the above change.

2000-07-11 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_mroute.h: corrected the type of a member
of if_set{} from fd_mask to if_mask.
In response to PR sys/266 from pavlin@catarina.usc.edu.

2000-07-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6_rtr.c (rt6_deleteroute): do not
(automatically) delete the static route in rt6_deleteroute(), even
if it uses a dead router.

2000-07-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6.c: some clarifications about neighbor
cache manipulation (this change does not affect behavior from the
user side, though):
- removed the ND6_LLINFO_WAITDELETE status. Actually, we can just
call rtrequest(RTM_DELETE) for an unreachable
neighbor. Reference to the neighbor cache entry from a cahced
route will be freed at the next time the route is used.
- also, we do not have to call pfctlinput(PRC_HOSTDEAD) in
nd6_free() for the same reason.
- do not set/refer the RTF_REJECT flag in neighbor cache
manipulation. It was just for (IPv4) arp-flooding prevention,
which is not necessary ND for IPv6.

2000-07-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/route6d/route6d.c: removed "ifndef ADVAPI"
parts. Since the advanced API has already been standardized,
implemented, and deployed, we don't need to take care of the older
kernel behavior (which is even confusing).
* *BSD/usr.sbin/route6d/Makefile: removed the -DADVAPI flag
according the change.

Mon Jul 10 14:43:40 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/{libpcap,tcpdump}: use 7/3 snapshot.
* freebsd3/ports/w3m: upgrade to 0.1.11.p.

Sun Jul 9 21:50:54 JST 2000 itojun@iijlab.net
* *bsd*/sys/netinet/tcp_input.c, kame/sys/netinet6/tcp6_input.c:
be more cautious about tcp option length field. drop bogus ones
earlier.
not sure if there is a real threat or not, but it seems that there's
possibility for overrun/underrun (like non-NOP option with
optlen > cnt). the bug is from 4.4BSD.

Sun Jul 9 13:39:22 JST 2000 itojun@iijlab.net
* libinet6/getaddrinfo.c: do not mistakenly accept empty scopeid.

Sun Jul 9 12:29:24 JST 2000 itojun@iijlab.net
* freebsd4/sys/net/if_ethersubr.c: repair IPV6_JOIN_GROUP(::).

Sat Jul 8 12:11:34 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/bind9: use bind 9.0.0b5
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 7/3 snapshot.

Sat Jul 8 10:57:36 JST 2000 itojun@iijlab.net
* {netbsd,openbsd}/usr.sbin/inetd: allow square-bracket for the first
element on inetd.conf, to disambiguate IPv6 address and colon
separator.
* openbsd/usr.sbin/inetd: handle IPv6 address in first element on
inetd.conf line.

Sat Jul 8 09:43:26 JST 2000 itojun@iijlab.net
* {bsdi3,openbsd,netbsd}/libexec/ftpd: plug setproctitle issue in
CERT Advisory CA-2000-13. NOTE: bsdi3 uses wu-ftpd. it may have
other vulnerabilities left in the code.
* netbsd/usr.sbin/inetd: improve error handling on getaddrinfo
(determine listening socket address). hints from enami.

Fri Jul 7 21:39:33 JST 2000 itojun@iijlab.net
* various places: audit use of printf-like functions, including
errx?, warnx?, setproctitle, and syslog. if we pass user-supplied
variable alone to these functions, they can be hosed by malicious
%-format string. from openbsd.

Thu Jul 6 20:43:57 JST 2000 itojun@iijlab.net
* openbsd/sys/netinet/tcp_*.c: remove IPv4 mapped support completely
from inbound packet processing. there were some corner cases not
covered by the code, and it caused SEGV due to inconsistency in
address family. sync with openbsd-current.

2000-07-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/rtadvd/if.c (if_getflags): made sure to close a
temporary socket to avoid making garbage sockets.

bsdi3/sys/i386/isa/{if_wi.c,if_wireg.h,wiioctl.h}
bsdi3/usr.sbin/wiconfig, bsdi3/usr.sbin/Makefile
ported WaveLAN driver and its configuration program from bsdi4

* {netbsd,openbsd,freebsd4}/lib/libinet6/getaddrinfo.c,
kame/libinet6/getaddrinfo.c:
return EAI_NODATA, instead of EAI_NONAME, on name resolution errors.
EAI_NONAME does not make sense in these situations
From: enami

Wed Jul 5 11:02:03 JST 2000 itojun@iijlab.net
* freebsd4: add netstat -sn -f pfkey.

Wed Jul 5 10:40:53 JST 2000 itojun@iijlab.net
* freebsd[234]: split IPv6 path MTU discovery-related sysctl from
net.inet.ip tree. FreeBSD SYSCTL_xxx does not have a way to report
duplicated definition into the same variable, it bites us many
times...

Wed Jul 5 02:25:11 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
Implemented INITIAL-CONTACT.
This message is sent by single notify message after phase 1 established
immediately. It means the message is not included last exchange on
phase 1. So it can be sent by responder on aggressive/base mode.
If there is no remote address in contacted list, racoon sends the
message to peer. If the message is received, racoon deletes all
IPsec-SAs relatived to peer's address. It takes place both initiator
and responder side.

Tue Jul 4 21:36:16 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
Racoon usually runs in background. If you specify -F option, you make
her running in foreground.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/mip6.c (mip6_add_ifaddr): use in6_update_ifa()
to assign an address instead of coping code from in6.c

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_update_ifa): newly added to update
parameters of an IPv6 interface address.
Basically, this function does nothing new, but made in6_control()
simple.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_control): completely obsoleted
SIOCSIFADDR_IN6, SIOCSIFDSTADDR_IN6, and SIOCSIFNETMASK_IN6.
We are quite confident there is no application that used these
commands, but if one exists, please let us know.

Tue Jul 4 18:33:20 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
don't delete phase 1/2 handler if some internal error occurs.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_is_ifloop_auto): removed an `ifdef'
part for openbsd, which made the function always return 0.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_unlink_ifa): newly added to release
various links for in6_ifaddr when deleting an address.
This function is also called from in6_control(), in order to
prevent the kernel from keeping a garbage structure on failure of
address addition.

Tue Jul 4 13:26:56 JST 2000 sakane@ydc.co.jp
* kame/sys/key.c:
A patch from <Francis.Dupont@enst-bretagne.fr> applied.
- fixed a interval to call key_timehandler.
- fixed a typo.
- added a value to be returned when some error happen.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_control): added several
improvements for sharing a single prefix with multiple addresses:
- install an interface direct route only when there's no shared
prefix. We'll never see unexpected EEXIST errors with this fix.
        - call in6_ifaddloop()/in6_ifremloop() whenever necessary.
        - do not call in6_ifaddloop()/in6_ifremloop() unless necessary.
        - added several clarifications according to the ipv6 address
architecture.

2000-07-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/bgpd/main.c (main_listen_accept): set the receiving
interface when accepting an on-link bgp connection.
* kame/kame/bgpd/bgp.c (bgp_process_open): detected a proper peer
for an incoming IBGP open message with link-local address.
These changes enabled an IBGP peer using link-local addresses.
Suggested by: Tomomi Suzuki <stomomi@ebina.hitachi.co.jp>

Tue Jul 4 10:25:13 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- Process to send a delete notify message only when phase 2 has
been established.
- added "dead" flag to a schedule. It is used to mark a schedule
already dead. don't delete a schedule at multiple place.

Tue Jul 4 08:44:11 JST 2000 itojun@iijlab.net
* netbsd/usr.sbin/inetd: remove duplicated ipsec initialization code
(used on SIGHUP).

2000-07-03 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/bgpd/bgp.c (connect_try): made sure to zero-clear a
newly allocated buffer.
Report from: Tomomi Suzuki <stomomi@ebina.hitachi.co.jp>

Mon Jul 3 11:50:12 JST 2000 itojun@iijlab.net
* kame/sys/netinet/icmp6.h: avoid bitfields in router renumbering packet
declaration. XXX standards?

2000-07-02 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_input.c (ip6_input): immediately discarded
a packet to an unready (i.e. tentative or duplicated) address with
logging.
This change reflected recent discussion in the ipngwg ML.

Sun Jul 2 11:24:52 JST 2000 itojun@iijlab.net
* netbsd/sys/netinet/tcp_input.c, kame/sys/netinet6/in6_pcb.c:
repair netbsd faith support. (1) tcp6_input dropped faith'ed
connections (2) in6_pcblookup_connect() was too strict.

Sat Jul 1 20:57:57 JST 2000 itojun@iijlab.net
* kame/faithd: make it possible to invoke faithd(8) from inetd(8).
benefits: allows us to access-control inbound traffic by using
hosts.allow(5).
possible drawbacks: inetd mode has no chance for multi-connection-
per-single-process enhancement. current faithd(8) needs 1
process per 1 connection anyways.

<200006>
Fri Jun 30 17:45:23 JST 2000 sakane@ydc.co.jp
* freebsd[34]/usr.bin/whois.c:
ported whois for IPv6/4.

Thu Jun 29 16:24:35 JST 2000 itojun@iijlab.net
*/sys/netinet/in.c, kame/sys/netinet6/in6.c:
inhibit EEXIST from in{,6}_ifinit(). history: (1) 4.4BSD ignores
return value from in_ifinit() completely. (2) previous kame code
tried to handle error case better, the change raised bogus EEXIST
to the userland on two-address-from-same-prefix assignment.

Thu Jun 29 10:14:47 JST 2000 itojun@iijlab.net
* faithd/faithd.c, natptd/main.c, natptlog/natptlog.c: be more careful
about arg to syslog(3), to prevent possible buffer overrun.
From: deraadt@openbsd.org

2000-06-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dhcp6: several minor improvements:
- daemonized dhcp6c.
- reactivated dhcp6c agains a SIGHUP signal or change of the
default route.
- changed logging based on syslog(8).

2000-06-28 SUZUKI Shinsuke <suz@kame.net>
* kame/sys/netinet6/ip6_fw.c

Wed Jun 28 15:01:09 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
improved sending a notify message including delete payload.
It's sent when one of below situations happens:
o receiving SADB_DELETE message from kernel.
o receiving SADB_FLUSH message from kernel.
o flushing phase2 handler.

2000-06-20 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/net/if_gif.c (gif_ioctl): made sure to cast the
argument to in6_aliasreq{} for the SIOCSIFPHYADDR_IN6 command.
Without this, the validation check would reject correct requests;
i.e. you couldn't configure IPv6 physical addresses.
In response to a report from FUJIURA Toyonori <toyo@jp.freebsd.org>

2000-06-20 SUZUKI Shinsuke <suz@sdl.hitachi.co.jp>
* kame/kame/ndp/ndp.c (delete, get)

* freebsd3/ports/mozilla: upgrade to M16

Tue Jun 20 12:49:28 JST 2000 itojun@iijlab.net
* sys/netinet6/in6_proto.c: disable rate limitation for ICMPv6 error,
since (1) it makes no sense to put less-than-10ms value to here
due to UNIX timer resolution, and (2) it seems wrong to rate-limit
without considering content of the payload (like ICMPV6 type/code).
we still have pps limitation. based on comments from kjc.

Tue Jun 20 11:44:19 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/bind9: use bind 9.0.0b4.

2000-06-19 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_ctloutput): corrected logic
of error detection for sooptcopyin(). This will fix the problem
that traditional RFC2292 compatible mode did not work for some
socket options (e.g. IPV6_PKTINFO) on freebsd[34].

Mon Jun 19 18:23:15 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
A path name in configuration file is always complemented if it is

never be complemented.

Mon Jun 19 16:51:24 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
If "non_auth" is defined in racoon.conf, any transform of AH proposal
including "non_auth" is not sent to the peer.

2000-06-19 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_output): jumped to the
"freehdrs" label before making the header chain in order to avoid
possible memory leak.
In response to the KAME problem report sys/259.

Mon Jun 19 07:41:31 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_{init,send}.c: be more backward-compatible with

nsaddr_list.sa_len.

Mon Jun 19 04:42:55 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 6/12 snapshot from

limitation.

Fri Jun 16 05:01:24 JST 2000 itojun@iijlab.net
* openbsd/sys: sync with OpenBSD 2.7
TODO: userland cleanup. tests (i386/conf/GENERIC.KAME compiles but
not tested).
kame/openbsd/ports does not work. we may want to remove those.

If you wish to upgrade to KAME-on-OpenBSD 2.7, make sure to
perform "make clean" at the top level to nuke symlinks, like:
% make TARGET=openbsd clean update prepare

make VERY sure that you use kame-supplied tools (like
/usr/local/v6/sbin/ping6) instead of normal ones (/sbin/ping6)
if you use KAME-enabled kernel. there are API changes between them.

* kame/kame/racoon/cfparse.y:
In racoon.conf, the path of configuration file is complemented by
include directive only if there is no '/' in the path.

Thu Jun 15 13:08:25 JST 2000 iotjun@iijlab.net
* sys/netinet6/ipsec.[ch]: net.inet.ipsec.inbound_call_ike sysctl
MIB is now gone for good.

Thu Jun 15 10:01:47 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_init.c: make _res.nsaddr_list initialization
more conservative when resolv.conf is missing (or there is no
"nameserver" line). previous code chokes on IPv4-only kernel.
merge from netbsd-current.

2000-06-15 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6_rtr.c (defrouter_msg): was added to tell
user processes changes about the default router (including
deletion). This function would be called from defrouter_addreq,
defrouter_addifreq, and defrouter_delreq.
Note: this is currently experimental and is only enabled with the
ND6_USE_RTSOCK kernel compilation option.

Thu Jun 15 02:18:24 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/zebra: upgrade to 0.87.

"class" conflicts with C++ reserved identifier.
From: Graham Wheeler <gram@cequrux.com>

2000-06-14 SUZUKI Shinsuke <suz@sdl.hitachi.co.jp>
* sys/net/if_dummy.c, freebsd4/sys/conf/files:
dummy I/F is available on FreeBSD4.0, too.

* freebsd4/sys/conf/options, freebsd4/sys/conf/files
freebsd4/sys/sys/mbuf.h
FreeBSD-4.0 KAME with MIP6 option is available.
add mbuf flag M_PROTO6 and use it for M_MIP6TUNNEL.

Wed Jun 14 20:14:47 JST 2000 itojun@iijlab.net

Tue Jun 13 20:08:38 JST 2000 itojun@iijlab.net
* openbsd/sys/netinet/udp_usrreq.c, openbsd/sys/netinet6/raw_ipv6.c:
correct scoped address handling.

2000-06-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_purgeaddr): tried to restore an
interface direct route if we have an address that shares the same
prefix with the deleted address.
This would improve behavior in multi-address environments;
if you assigned multiple addresses that shared a same prefix and
then remove one of them, the interface direct route corresponding
to the address would still remain.

2000-06-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6.c (in6_ifremloop): always called
in6_ifloop_request regardless of the result of
in6_is_ifloop_auto(), in order to make sure to invalidate a stale
route entry for a deleted address.
Note: bsdi doesn't need this fix.

2000-06-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_input.c (ip6_input): avoided to use the
cached route for forwarding, if it is down.
This fix would prevent the input routine from accepting a packet
to already removed address.

Tue Jun 13 14:29:12 JST 2000 itojun@iijlab.net
* netbsd/sbin/setkey: move setkey from usr.sbin/setkey to sbin/setkey.
we need it for encrypted NFS (sync better with netbsd-current).

Tue Jun 13 14:07:24 JST 2000 itojun@iijlab.net
* kame/racoon/safefile.c: be more picky about secret file permission.
now pre-shared key file (psk.txt) is required to be owned by the
uid running racoon (= root), and must not be accessible by others
(like 0400).

2000-06-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6_rtr.c (in6_ifadd): made sure to gain a
reference counter to in6_ifaddr for the autoconfigured address
in bsdi and freebsd2 cases.
This fix would be important to those OSes, since the older code
woulde cause duplicated free when the lifetime for the address
expired.

2000-06-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dhcp6/common.c (getifaddr): corrected arguments to
in6_addrscopebyif().

Mon Jun 12 JST 2000 itojun@iijlab.net
* sys/netkey/key.c: transmit SADB_X_SA2 from kernel to userland
on SADB_ADD and SADB_UPDATE. without it latest racoon does not work.

Mon Jun 12 12:34:02 JST 2000 itojun@iijlab.net
* libinet6/getnameinfo.c: use EAI_xx for error code. rfc2553bis
suggests it. the commit corrects old behavior on invalid socket,
where getnameinfo returned 0 (success).

Mon Jun 12 08:51:25 JST 2000 itojun@iijlab.net
* sys/netkey/key.c: correct prefix length match on destination address.

statistics counters about error messages (see below).

2000-06-12 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet/icmp6.h: added a new structure icmp6errstat{}
to count more precise statistics of error messages to be generated.
* kame/sys/netinet6/icmp6.c (icmp6_errcount): added as a new
function in order to count the precise statistics.

2000-06-12 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* *bsd*/usr.[s]bin/netstat/inet6.c (ip6_stats): printed new
statistics counters of forward cache for incoming packets (see
below).

2000-06-12 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_var.h (ip6stat): added members to count
statistics of forward cache for incoming packets.
* kame/sys/netinet6/ip6_input.c (ip6_input): counted the
statistics.

Sun Jun 11 17:03:07 JST 2000 itojun@iijlab.net
* {netbsd/pkgsrc/net,freebsd[23]/ports}/{libpcap,tcpdump}: use
2000/6/5 weekly SNAP from tcpdump.org.
* netbsd/pkgsrc/net/ethereal: upgrade to 0.8.9.

Sat Jun 10 23:11:41 JST 2000 sakane@ydc.co.jp
* kame/sys/netkey/key.c:
* kame/kame/libipsec/pfkey.c:
* kame/kame/setkey/parse.y:
Obsoleted mode specification. You don't need to specify a mode of
SA when you get/delete SA by setkey. Also, it's not need to do
pfkey_send_delete/pfkey_send_get().

Sat Jun 10 15:42:25 JST 2000 sakane@ydc.co.jp
* kame/sys/{netkey/key.c,net/pfkeyv2.h}:
* kame/kame/{stekey,racoon,libipsec}:
Moved mode/reqid to new extension from sadb_msg header.
New extension is defined sadb_x_sa2 structure.

Fri Jun 9 10:10:08 JST 2000 itojun@iijlab.net
* *bsd*/sys/netinet6/in6_pcb.c, kame/sys/netinet6/in6_src.c:
add in6_embedscope() and in6_recoverscope(), to avoid code duplicate
for KAME scopeid hack.
* {bsdi4,openbsd}/sys/netinet6/in6_pcb.c: add scope consideration
to in6_pcbbind.

Thu Jun 8 22:58:24 JST 2000 itojun@iijlab.net
* kame/ping6/ping6.c: make sure to clear ni_flags on ping6 -w
or ping6 -W. From: yoshfuji

Thu Jun 8 21:40:55 JST 2000 itojun@iijlab.net
* *bsd*/sys/netinet6/{udp6_output,raw_ip6,in6_pcb}.c:
do not overwrite sockaddr on PRU_SEND nor PRU_CONNECT.
(the change is very important)

Wed Jun 7 22:21:43 JST 2000 itojun@iijlab.net
* sys/netinet6/in6_prefix.c: check interface matches when adding
new interface addresses, based on new link-local address and
prefix information. old code added new interface address without
checking interface match and ended up many bogus new interface
addresses.

Tue Jun 6 22:41:24 JST 2000 itojun@iijlab.net
* bsdi4/sys/netinet/tcp_input.c: fix INP_IPV6_MAPPED configuration
onto inpcb. the mistake caused ND to behave badly (ND tries to
update reachability info for IPv4 mapped address - one more reason
to hate IPv4 mapped address).
From: dab@bsdi.com

Tue Jun 6 22:16:18 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/www/wwwoffle: upgrade to 2.5e.

Tue Jun 6 21:53:54 JST 2000 itojun@iijlab.net
* bsdi4/sbin/sysctl: correctly handle IPv6 ipsec/pim entries.

2000-06-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/libexec/tftpd/tftpd.c: do not connect tftp session
sockets. Instead, check consistency of the client's local port.
In response to PR: sys/254

2000-06-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/usr.bin/tftp/tftp.c:
        - do not blindly copy server's port, but make sure to check its
consistency during a session.
        - copy the whole received sockaddr (i.e. not only port) for the
next sendto(), which would be safer if the server has bound its
local address.

2000-06-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/ports/bind9, netbsd/pkgsrc/net/bind9:
upgraded to bind-9.0.0b3. KAME users are recommended to use this port,
because the original version has an API compatibility issue in a
multi-address environment.

2000-06-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi3/sbin/sysctl/sysctl.c:
* {netbsd, openbsd}/usr.sbin/sysctl/sysctl.c:
synch with the change below. (Fortunately, there are no binary
compatibility issues).

2000-06-06 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/pim6_var.h: renamed macro definitions about
pim6 sysctls to avoid possible conflict.
Suggested by: Hitoshi Asaeda <asaeda@yamato.ibm.co.jp>

Mon Jun 5 21:56:35 JST 2000 itojun@iijlab.net
* traceroute6/traceroute6.c: add -f (skip first hops). the option
is common to freebsd4/bsdi4/openbsd/netbsd traceroute(8).

2000-06-05 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/traceroute6/traceroute6.c (main): set a minimum set of
socket options as soon as opening a raw socket to avoid
unintentionally receiving packets without ancillary data.
Note: this could actually happen when we used an unreachable IPv6
DNS server.

2000-06-05 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6_src.c (in6_pcbsetport): supported FreeBSD
3 and later as a separate function, the code which was a part of
in6_pcbbind().

2000-06-05 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/udp6_output.c (udp6_output): supported FreeBSD
3 and later.
* freebsd[34]/sys/netinet6/udp6_usrreq.c: removed original
udp6_output().
* freebsd[34]/sys/conf/files: added netinet6/udp6_output.c

2000-06-05 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd[34]/sys/netinet6/udp6_usrreq.c (udp6_send): added some
validation checks for the passed sockaddr. The previous code seemed
a bit naive.

Sun Jun 4 22:28:30 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_send.c: remove MULTICASTQUERY6 case.
it is unnecessary since we have mdnsd, and it was mistake in BIND9
that BIND9 replied to multicast queries.

Sun Jun 4 21:57:47 JST 2000 itojun@iijlab.net
* sys/netinet6/nd6.c: revise upper-layer reachability confirmation
hint processing. count hints from upper-layer, and if the count
reaches maximum, try to probe reachability by real ND.
sysctl net.inet6.icmp6.nd6_maxnudhint defines maximum # of subsequent
upper-layer hints to be accepted.
we have removed check against process privilege for IPV6_REACHCONF.

we currently have two sources for hints: (1) IPV6_REACHCONF
(2292bis setsockopt), and (2) hints from tcp_input.
it is still questionable if they are really trustworthy.
for example, rogue userland program can use IPV6_REACHCONF to confuse
ND process (which is system-wide cache). also, tcp_input can be
hosed by hijack attempts.

Sun Jun 4 12:29:41 JST 2000 itojun@iijlab.net
* sys/netinet6/mip6*: sync with latest MIPv6 patch from ericsson guys.
- New addition to eager movement detection: now a second level
provided to enhance handoff time a lot. As soon as a
new prefix is heard the Mobile Node changes default
router. Less stable, router reachability is not assured,
but this can make handoff go in less than 0.5 sec. Also:
nasty trick used is to run nd6_timer() five times per
second. Use "mip6config -e 2" to test.
- More consistent function of mip6config and mip6stat.
- Fixed some bugs in mip6stat.
- Code clean up.

Sun Jun 4 01:12:52 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* {freebsd3/ports, netbsd/pkgsrc/net}/p5-Socket6: upgrade to 0.07.

Sat Jun 3 08:08:43 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/{libpcap,tcpdump}: use 2000/5/29 weekly snap.
* freebsd3/ports/mod_perl: mod_perl-1.24.tar.gz

2000-06-02 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/netinet/tcp_subr.c (tcp6_ctlinput): separated from
tcp_ctlinput. We believe a separated function would make sense
in this case.
Additionaly, the new function now calls syn_cache_unreach().
IMO, there's been no special reason not to call it.

* openbsd/sys/netinet/tcp_subr.c (tcp6_ctlinput): applied the same
fix as bsdi4.
Also, the ctlinput function now calls in6_pcbnotify(), which was
unintentionally (IMO) prohibited.

2000-06-02 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4, freebsd[34], openbsd}/sys/netinet6/in6_pcb.c
(in6_pcbnotify):
* kame/sys/netinet6/in6_pcb.c (in6_pcbnotify):
corrected the algorithm to detect whether in6_rtchage() should
be called.

Fri Jun 2 21:08:22 JST 2000 itojun@iijlab.net
* freebsd2/ports/{libpcap,tcpdump}: use 2000/5/29 weekly snap.

Thu Jun 1 04:47:42 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- You must explicitly specify the file name of certificate and
private key if you use a certificate. See README.certificate.
- fixed to make a index of SPD in responder side when ID type in ID
paload is subnet, or when there is no ID payload.
- supported to negotiate the IPsec-SA of ESP without authentication.
- Added the direction as an item to compare policy.
- fixed some crash problems.

Thu Jun 1 02:43:31 JST 2000 itojun@iijlab.net
* kame/mdnsd: multicast DNS resolver, as specified in
draft-aboba-dnsext-mdns-00.txt. Note that spec conformance is
still very low.
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 5/29 weekly snap.

<200005>
2000-05-31 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_mloopback): make a deep copy
of the IPv6 header only in an M_EXT case. Practically, we'll
rarely need such an extra copy.

Tue May 30 23:56:04 JST 2000 itojun@iiljab.net
* sys/netinet6/ip6_output.c: make scopeid handling in multicast
loopback case (ip6_mloopback) consistent with other cases.

Tue May 30 20:54:23 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_send.c: with #define MULTICASTQUERY6, allow
multicast address in /etc/resolv.conf "nameserver" line. By
configuring resolv.conf(5) like below:
nameserver ff02::1%3
DNS queries will reach all nodes on the link with link ID "3".
With the change, the resolver code changes some of its behaviors:
- the resolver code does not check src/dst pair match, if we have
multicast address in resolv.conf. It may or may not raise security
issue.
- the resolver code does not use connected udp socket for multicast
query.

highly experimental - note that this change DOES NOT attempt to
support multicast DNS queries, as drafted in
draft-aboba-dnsext-mdns-00.

2000-05-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/faithd/faithd.c (main): allocated enough memory for
serverpath and serverarg to prevent possible buffer overrun.

Tue May 30 11:18:03 JST 2000 itojun@iijlab.net
* freebsd[23]/ports/popper, netbsd/pkgsrc/mail/qpopper:
mark the port broken for security issue. users are suggested to
remove the installed binary.
http://www.securityfocus.com/templates/archive.pike?list=1&date=2000-05-22&msg=p04320305b5511470392c@[192.168.1.5]

Tue May 30 01:29:04 JST 2000 itojun@iijlab.net
* freebsd4/sys/net/if_loop.c: check BPF data link layer type (DLT_xx)
on call to bpf_mtap() in if_simloop().

XXX if_simloop() call from ip6_output() causes junk to be injected
to bpf buffer. we may need some fix separately from this commit.

Tue May 30 00:11:17 JST 2000 itojun@iijlab.net
* {bsdi4,netbsd}/usr.bin/ftp: internally convert IPv4 mapped address
into real IPv4 address. IPv4 mapped address adds too much confusion
to FTP protocol handling.
Suggested by: ume

Mon May 29 08:34:58 JST 2000 itojun@iijlab.net
* kame/sys/netinet/in6_pcb.c (affects netbsd only):
bind(2) on AF_INET6 socket with IPv4 mapped address will raise error,
instead of making port number duplicate on pcb struct.

Mon May 29 02:26:25 JST 2000 itojun@iijlab.net
* bsdi4/sys/netinet/tcp_input.c: correct critical typo. prior to the
change, if we have inbound IPv4 TCP traffic to AF_INET6 socket.
inp_laddr6 will have ::ff0f:xx.yy.zz.uu, not ::ffff:xx.yy.zz.uu.
* bsdi4/usr.sbin/netstat/inet.c: do not print IPv4 mapped address
as normal IPv4 address, on netstat -an. print it as is (as IPv4
mapped).

Mon May 29 00:43:15 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_output.c (affects netbsd only):
correct setsockopt(IPV6_BINDV6ONLY) behavior.

Mon May 29 00:04:15 JST 2000 itojun@iijlab.net
* bsdi4/sys/netinet/in_pcb.c: remove NRL bind(2) ordering constraint.
NRL code forbids wildcard IPv4 bind after wildcard IPv6 bind on
the same port number. it was mistake. now bind(2) is free from
ordering constraint.

Sun May 28 15:33:11 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 2000/5/22 weekly snap.

Sat May 27 23:05:00 JST 2000 itojun@iijlab.net

2000-05-27 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dtcp/dtcpc.rb: added a new option "-r (static|solict)"
to specifiy how the default route should be configured.

2000-05-27 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/rtadvd: became more conscious of interface status
(up or down);
        - when an interface becomes down, stop the corresponding timer.
- when an interface becomes up again, reinitialize the status and
restart the timer.
- simply discard data received on a daed interface.
- dump if interface is up or dump

Sat May 27 19:07:58 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: add net.inet6.icmp6.errppslimit sysctl MIB.
it will let you limit ICMPv6 error messages by pps, not interval.
still not sure what is the best way to perform rate limitation...
change default parameter for icmp6 error rate/pps limitation
to 100usec interval and 200pps (an icmp6 error packet needs to
pass both tests to leave the node).

Sat May 27 15:18:58 JST 2000 itojun@iijlab.net
* kame/ping6/ping6.c: support -N option to probe NI group address at
ease. for example:
% ping6 -N -I ne2 lychee
will probe NI group address for nodename "lychee", instead of the
address resolved for "lychee".

Sat May 27 14:01:29 JST 2000 itojun@iijlab.net
* sys/netinet6/in6_ifattach.c: on in6_ifattach(), join NI group address
specified in icmp-name-lookup-04 and beyond.
TODO: cope with hostname change events, like sethostname(3).

Fri May 26 00:02:15 JST 2000 itojun@iijlab.net
* netbsd/usr.bin/ftp/fetch.c: do not transmit scope identifier
on HTTP Host: directive. disallow scoped address if the access is
via proxy.
* openbsd/usr.bin/ftp/fetch.c: do not transmit scope identifier on
HTTP Host: directive. correct Host: directive passing if the
access is via proxy.
TODO: disallow scoped address if the access is via proxy.

Thu May 25 23:16:01 JST 2000 itojun@iijlab.net
* bsdi4/usr.bin/telnet/commands.c: use getaddrinfo to be scoped-address
friendly.

Thu May 25 21:56:47 JST 2000 itojun@iijlab.net
* bsdi4/sys/i386/pci/if_exp.c: do not use interrupt for initializing
multicast filter. this will make exp driver to be friendly with
IPv6 initialization sequence. hints from netbsd fxp driver.

2000-05-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/net/route.c (ifa_ifwithroute): reverted a KAME
specific change introduced on 2000-02-25 (see this log file).
The change was an ad-hoc hack and broke BSDI's original
intention, so we've wanted to clarify the code.

2000-05-25 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6_ifattach.c (in6_ifattach,
in6_ifattach_addaddr): use rtrequest1() when assigning IPv6
addresses since this function is more conscious of interfaces than
rtrequest() and is suitable for link-local addresses.

Thu May 25 01:25:39 JST 2000 sakane@ydc.co.jp
* kame/sys/{netkey/key.c,netinet6/ipsec.c}:
* kame/kame/setkey:

test/experience reports.

2000-05-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dhcp6/dhcp6s.c: the "-n dnsserv" option can now be
specified multiple times, when a user wants to set more than one
server.

Wed May 24 18:59:55 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
fix to check vendor id. HASH function for vendor id is always MD5.

Wed May 24 18:09:12 JST 2000 itojun@iijlab.net
* sys/netinet6/in6.h: check parameter type to IN6_ARE_ADDR_EQUAL().
this should avoid typecast bugs like below.

2000-05-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4,openbsd}/sys/netinet6/in6_pcb.c (in6_pcbnotify):
corrected the 2nd argument IN6_ARE_ADDR_EQUAL(), which was
unintentionally "struct in6_addr **"".
This fix is quite important for stability and users of those OSes
are recommended to apply it.

Wed May 24 14:32:44 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
supported pre-shared key written by hex string.

Wed May 24 01:29:46 JST 2000 itojun@iijlab.net

and stock netbsd142 pppd may choke.

Tue May 23 21:51:00 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
fix to get local address to be used by sending address. It was
enbugged when some macro was removed.

Tue May 23 07:41:08 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
don't bark when the life duration of attribute in SA payload is
encoded TV format. It's allowed by RFC.

Tue May 23 07:14:59 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
some fixes.
- initialize prefixlen at ipsecdoi_id2sockaddr.
- check sainfo duplicated.
- improve sainfo2str() to return "anonymous" if sainfo is anonymous
record.
- fix to parase port number specification.
- change output level during parsing payload.

Tue May 23 01:46:39 2000 Shin'ichi Fujisawa <fujisawa@kame.net>
* Remove "options PM" from GENERIC.v6.

Now, the facility of v4NAT was integrated by NATPT (some NAT
  function is not implemented yet), please use NATPT when you want
  to use v4NAT.

Tue May 23 00:27:52 JST 2000 itojun@iijlab.net
* sys/netinet6/udp6_var.h: make sysctl symbol name meet with
IPv4 counterpart. freebsd2: net.inet6.udp6.maxdgram,
netbsd: udp6.sendspace, bsdi3: udp6.sendmax.

Mon May 22 21:08:55 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: disallow negative numbers for ICMPv6 rate limit
interval. use ratecheck(9) if exists (this will make
netbsd15/openbsd27 merger easier).

Mon May 22 17:54:29 JST 2000 itojun@iijlab.net
* sys/netinet6/{ah,esp}_output.c: correct rare error case handling
(do not leak mbuf/do not emit incomplete packet).
* sys/netinet6/ah_*.c: cope with memory allocation failure more
gracefully.

2000-05-22 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>

the new flag was added as specified in rfc2553bis-00.

Mon May 22 13:19:29 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: to conform better with icmp-name-lookup-05,
make the validation rule more strict for node information query.
now, IPv6 destination address must be anycast/unicast for the node,
or link-local multicast.
there still are spec non-conformance - see comments in icmp6.c.

Mon May 22 12:07:28 JST 2000 itojun@iijlab.net

2000-05-19 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_mroute.c (ip6_mdq): loosened scope check
in ip6_mdq() for packets forwarded to a register I/F. Without
this, such packets could be mistakenly discarded.
In response to: a report from Noriaki Takamiya
<takamiya@po.ntts.co.jp>

Fri May 19 11:41:05 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_mroute.[ch]: add backward compatibility code
for 2000/4/12 mrt6msg change (is not used in kame tree).
freebsd40 and openbsd27 are shipped with old declaration, so we
need to provide backward compat to some degree.

Fri May 19 09:26:28 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd4/{usr.bin/fetch, lib/libftpio}: support IPv6.

* {bsdi4, freebsd[34], openbsd}/sys/netinet6/in6_pcb.c:
filled default scope zone in sin6_scope_id if unspecified.
        Currently, these are enabled only with the ENABLE_DEFAULT_SCOPE
kernel compilation option.

2000-05-18 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_forward.c (ip6_forward): zero-cleared
embedded link zone IDs in forwarded packets. We forgot this, since
old kernel did not allow link-scope packets to be forwarded.

2000-05-18 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/ndp/ndp.c (set): supported <link-local_addr>%<link ID>
for "ndp -s".

Thu May 18 21:15:32 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/fetchmail: upgrade to 5.4.0

Thu May 18 16:34:18 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/mail/fetchmail: upgrade to 5.4.0.

Wed May 17 23:58:14 JST 2000 itojun@iijlab.net
* {netbsd/pkgsrc, freebsd[23]/ports}/net/{libpcap,tcpdump}: use 5/15
weekly snap.

Wed May 17 21:50:27 JST 2000 sakane@ydc.co.jp
* {freebsd[234],netbsd}/sys/netinet/ip_output.c:
call key_spdacquire() if there is no policy entry for IPv4.
key_spacquire() sends a setup policy request to the policy
negotiating daemon or something.

2000-05-17 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6.c (nd6_output):
* kame/sys/netinet6/ip6_output.c (ip6_output):
made scoped addresses more friendly with loopback interfaces;
if a packet containing scoped addresses in the source or
destination address fields is going to be sent on a loopback
interface, pass looutput() the interface to which the scoped
address(es) belongs.
For example, you won't see "lo0" when you ping to your own
link-local address.
This is currently experimental and enabled only when the
FAKE_LOOPBACK_IF kernel compile option is specified.

Wed May 17 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: correct node information lookup, when
the query is formatted in 05 draft format and IPv6 multicast
address is attached as subject. this will make node to reply to
"ping6 -w ff02::1" like before (actually, validation rule is not
really conformant to 05 draft. see comments in source for details).

Wed May 17 19:09:51 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* kame/freebsd3/ports/{squid11, qmail}: upgrade to latest IPv6
patch.
* kame/freebsd3/ports/{quake6, quakedata}: use IPv6-migrated
quakeforge.

2000-05-17 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/scope6config/scope6config.c: added a new syntax
"scope6config default" to see the default zones.

2000-05-17 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/{in6.c, nd6_rtr.c, scope6.c}: introduced the
notion of "default scope zones":
- store the default zones in scope6_ids[0]
- reflect change of default interface to default link
        - added a new ioctl SIOCGSCOPE6DEF to get the default values

2000-05-17 SUZUKI Shinsuke <suz@sdl.hitachi.co.jp>
* bsdi3/sys/net/if_tun.c:
- fixed mbuf allocation bug on tun?
- enabled IPv6 addressing on tun?
* {freebsd[23]/ports,netbsd/pkgsrc/net}/gated-ipv6
updated to May 11's snapshot

Wed May 17 10:09:42 JST 2000 itojun@iijlab.net
* kame/sys/net/if_gif.c: with "options XBONEHACK", allow multiple
gif tunnels to be configured with the same pair of outer addresses.
From: Lars Eggert <larse@isi.edu>
* kame/sys/net/if_gif.c: always disallow multiple multi-dest tunnels.

2000-05-16 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dhcp6/common.c (getifaddr): corrected the 2nd argument
to in6_matchflags().
* kame/kame/dhcp6/dhcp6s.c (server6_react_solicit,
server6_react_request): corrected scope validation for incoming
packets.

Tue May 16 23:05:56 JST 2000 itojun@iijlab.net
* kame/route6d/route6d.c: memory leak and bzero() correction.
* kame/route6d/route6d.c: correct interface address handling
for global address on p2p interface. there seem to be two major
models in this arena: cisco (use addr/plen) and gated (advert
dest/128 and addr/128). the code supports both behavior,
switchable at compilation time. default behavior is "gated".
we may need to revisit the code later. Comments from suz on p2p
routing model.

Tue May 16 09:44:50 JST 2000 itojun@iijlab.net
* netbsd/usr.bin/ftp/fetch.c: parse RFC2372 ftp URL correctly.
(the code is different from netbsd-current code - netbsd-current
code works just right, and our version will go away when we switch
to kame/netbsd15)

Mon May 15 22:39:20 JST 2000 itojun@iijlab.net
* openbsd/usr.bin/ftp/fetch.c: parse RFC2372 ftp URL correctly.

2000-05-15 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/v6test/conf/ext.conf (jumbolack): added to see if the
target is coformant to the 1st validation in Section 3. of rfc
2675.

2000-05-15 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_input.c (ip6_input): if ip6_plen == 0 &&
HbH is included && no jumbo opt, return icmp6 error and discard
packet. This is a new validation check added in RFC 2675.

Mon May 15 18:25:52 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: support DNS subject name in NI6 query.
receiving node will supress reply, if DNS subject name does not
match gethostname(3). truncated nodename case is little bit
questionable, see below.

Mon May 15 15:48:44 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c, kame/ping6/ping6.c:
use DNS name encoding for NI6 replies (DNS name).
the kernel code tries to be compatible with 03 draft (will reply
with pascal string to old "ping6 -w" or current "ping6 -W").
truncated nodename case is little bit questionable - many nodes are
configured with non-FQDN nodename, and we're not sure if we can
treat such name as FQDN for the node.

Mon May 15 02:35:41 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/{libpcap,tcpdump}: use tcpdump.org 2000/5/8
weekly snap

Sun May 14 JST 2000 itojun@iijlab.net
* sys/netkey: completely rewrite message management, to avoid possible
buffer overrun with corrupted pfkey data stream. since only root
processes are able to connect to pfkey socket, we don't consider
this as vulnerability (if a bad guy can inject corrupted data stream
to pfkey, he has root privilege and he can do many other things
as well). rewrite still in progress.
if you see any breakage with IPsec related operations, please report.
* sys/netkey: attach better proposal/combination payload to acquire
message from the kernel.

2000-05-14 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/usr.sbin/netstat: printed per-interface IPv6 statistics.
Please try
% netstat [-p [ip6|icmp6] | -f inet6] -s -I if_name
for printing statistics on a specified interface.

2000-05-14 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4, openbsd}/sys/netinet6/raw_ipv6.c (rip6_output):
- fixed memory leak for outgoing ancillary data
        - use KAME's checksum offset option for outgoing packets
        - count statistics for outgoing ICMPv6 packets
        - be more friendly with nervous compilers
        - code cleanup

Sat May 13 JST 2000 itojun@iijlab.net
* */usr.bin/telnet/commands.c: improve error message on invalid
port name. gai_strerror() does not give enough detail.
* netbsd/usr.sbin/inetd/inetd.c: improve error message on address
family mismatch.
* sys/netinet6/icmp6.c: improve icmp6 node information support.
we have not been conformant to the latest specification (05).
the current code is a mixture of 05 draft and 03 draft.
need more fixes (see comment in code for detail).

2000-05-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/gifconfig/gifconfig.c (in6_status): use getnameinfo
(instead of inet_ntop) to print IPv6 addresses.

2000-05-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4,openbsd}/sys/netinet6/in6_pcb.c (in6_setsockaddr): move
the embedded link ID of a link-local address to the sin6_scope_id
field in order to conceal the embedding hack from users.

2000-05-13 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/dhcp6: supported the latest draft (dhcpv6-15).
Note that this version is not compatible with the previous one,
and thus you should update whole your DHCPv6 system including
clients, relays and servers.

Thu May 11 19:28:22 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- fix to get lifetime/lifebyte from doi attribute.
- fix to lifetime/lifebyte handling.
lifetime of 0 should not be included a packet. 0 of lifebyte should
not be included in a packet although 0 means not to care of the
lifetime of bytes. If there is such case, it is rejected.
- modify racoon.conf.5.
- update version to 20000501 means proposal parser is fixed.

They are reported from <Francis.Dupont@enst-bretagne.fr>.

Wed May 10 14:07:22 JST 2000 itojun@iijlab.net
* sys/netinet/* (all platforms): correct more boundary checking issues
in ip options processing. This was 4.4BSD issue, and all *BSD
platforms are not very careful in parsing ip options.

Wed May 10 02:07:33 JST 2000 itojun@iijlab.net
* sbin/ping6: correct outbound NI query packet with -aw.
we should have attached Subject data, which was defined in
04 draft. (we are now in 05)
* sys/netinet6/icmp6.c: improve inbound NI query packet validation.

Tue May 9 22:11:56 JST 2000 itojun@iijlab.net
* all platforms: correct NetBSD Security Advisory 2000-002, problem (2).
this applies to all BSD-based operating systems. Kernel upgrade
is suggested if you run serious services with KAME kernel.

Mon May 8 23:24:34 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use tcpdump.org 2000/5/8
weekly snap.

Mon May 8 23:08:24 JST 2000 itojun@iijlab.net
* libinet6/name6.c: correct resolver error code handling (h_errno,
like last arg for getipnodebyname).

Mon May 8 17:20:17 JST 2000 itojun@iijlab.net
* freebsd4: ipsec now compiles (not tested at all).
brave testers wanted.

Sat May 6 01:48:14 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>

Sat May 6 00:30:39 JST 2000 itojun@iijlab.net
* */include/netdb.h, kame/libinet6/getnameinfo.c:
2nd arg of getnameinfo() is socklen_t, not size_t.
this was changed somewhere before rfc2553. we forgot to catch
up with the change.

Sat May 6 00:55:30 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>

opt_inet6.h and opt_ipsec.h

Fri May 5 15:59:21 JST 2000 itojun@iijlab.net
* kame/sys/netinet6/in6_ifattach.c: stabilize in6_ifdetach() again.
previous code touched uninitialized pointers.
* openbsd/sys/net/if.c: cope with pcmcia card removal.

2000-05-04 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6[ds]d/mld6_proto.c (accept_listener_query):
corrected incoming MLD query message handling.

Thu May 4 13:10:16 JST 2000 itojun@iijlab.net
* openbsd/lib/libinet6/getaddrinfo.c: translate resolver error codes
in h_errno into getaddrinfo error code. without this, EAI_FAIL
is always returned and it made no sense.
From: deraadt@openbsd.org

Mon May 1 19:38:32 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/net/{libpcap,tcpdump}: use 2000/5/1 weekly snap.

Mon May 1 18:24:04 JST 2000 itojun@iijlab.net
* sys/netinet6/ip6_output.c: avoid panic on ip6fw kernel configuration
on IPv6 packet outputs (usually, DAD on reboot).

Mon May 1 14:05:02 JST 2000 itojun@iijlab.net
* kame/libinet6/name6.c: use BIND 4.9.7 DNS answer parser to remove
any of vulnerability old name6.c might have.

Mon May 1 12:22:53 JST 2000 itojun@iijlab.net
* kame/libinet6: have more sanity check against validity of CNAME.
(there were some advisory about this in the past, IIRC)

<200004>
2000-04-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6[ds]d: did timeout the MLD querier correctly.

2000-04-30 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/netinet6/raw_ipv6.c: call ip6_mrouter_done() when the
ip6_mrouter socket is closed in order to avoid remaining a garbage
socket in the kernel.

2000-04-29 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/ports/bind9/Makefile: upgraded to bind-9.0.0b2.

2000-04-29 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6sd/cfparse.y:
* kame/kame/pim6sd/pim6_proto.c (receive_pim6_bootstrap):
ignored node-local and link-local group prefixes in the
configuration file and received bootstrap messages.

2000-04-29 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/nd6.c (nd6_output): do not try NUD unless the
gateway is a real neighbor. We can now enable NUD on a p2p link
even when
- assigning a pair of source and destinaion addresses on the p2p
link (with the /128 mask), or
- installing a direct route to the p2p link using an AF_LINK
gateway or a node's own address on another interface.

Sat Apr 29 02:11:18 JST 2000 itojun@iijlab.net
* freebsd4: fix various kame/freebsd4 sync issue, including KAME
PR 244. there can be more issues left - pls report if you find one.
* */libinet6/getaddrinfo.c, kame/libinet6/name6.c: correct
FILTER_V4MAPPED code. avoid unaligned memory accesses.

2000-04-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/pim6sd: filled the suggested hash mask length in
bootstrap messages. Also, that field is now configurable.
In response to a report from Olivier TOGNI
<togni@dpt-info.u-strasbg.fr>.

Fri Apr 28 19:30:18 JST 2000 itojun@iijlab.net
* ports/pkgsrc for zebra (openbsd, freebsd[23], netbsd):
upgrade to 0.86.

2000-04-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/traceroute6/traceroute6.c (main): always printed the

shared version defined in netinet6/udp6_output().

2000-04-27 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* {bsdi4, openbsd}/sys/netinet/in_pcb.c (in_pcbnotify):
* openbsd/sys/netinet/in_pcb.c (in_pcbnotifyall):
prevented an infinite loop, which could happen if an IPv6 PCB
entry exists and notification to the PCB list occurs.
OpenBSD users who use the 20000424 snap release are strongly
recommended to apply this fix.

Thu Apr 27 12:32:34 JST 2000 itojun@iijlab.net

vendorid directive is obsoleted. vendorid should not be configurable.

Wed Apr 26 21:23:49 JST 2000 itojun@iijlab.net
* {net,open}bsd/lib/libinet6/getaddrinfo.c:
disable AI_ADDRCONFIG support since it does not handle PF_UNSPEC
case. From: ume

Wed Apr 26 19:20:54 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_{comp,send}.c: incorporate strict boundary
checking from BIND 4.9.7. simplify #ifdefs.
* libinet6/resolv/res_send.c: force fragment to minimum IPv6 MTU when
we send a UDP query to IPv6 DNS server. this avoids path MTU
discovery from affecting name resolution.

Wed Apr 26 17:44:18 JST 2000 itojun@iijlab.net
* libinet6/resolv/res_query.c: clarify reasons for setbuf().
* freebsd4: sync with latest gif and stf code (compiled, need more
testing)

Wed Apr 26 12:00:59 JST 2000 itojun@iijlab.net
* libinet6/resolv: allow users to switch use of EDNS0 query packet,
by "options edns0" in /etc/resolv.conf. BIND9 DNS server must be
listed on "nameserver" line if you use EDNS0 query packet, since
BIND4/8 will choke with EDNS0 packets. highly experimental.
(not available in freebsd4 and bsdi4 due to resolver differences)

Tue Apr 25 16:46:56 2000 Shin'ichi Fujisawa <fujisawa@kame.net>
* v4 traceroute (in NAT-PT w/ v4NAT) works.

Tue Apr 25 16:21:24 JST 2000 itojun@iijlab.net
* netbsd/sys/netinet/ip_ipip.c: re-enable support for ipip interface.

In the case of ICMP{,V6}, check address family and upper layer protocol.

Tue Apr 25 03:54:32 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
enable VPN negotiation again.

XXX AS before, racoon can NOT negotiate the socket based SA.

2000-04-24 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/net/if.c (ifa_ifwithnet): reverted a change on
2000-02-25, since the logic is not related with our latest code.

Mon Apr 24 22:13:09 JST 2000 itojun@iijlab.net
* libpcap/tcpdump pkgsrc (netbsd/freebsd2): upgrade to 4/24 snapshot.

Mon Apr 24 21:39:23 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
- enable to define some algorithm each algorithm class.
- use internal SPD, don't SPDGET in order to get SP entry.
- fix to negotiate phase 2 with multiple transform in a single protocol.

Mon Apr 24 17:22:51 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
improve phase 2 configuration and parse phase 2 SA payload.
Racoon takes security protocols to be negotiated at phase 2 from
kernel's SPD.
User can define algorithms, lifetime and pfs by "sainfo" directive.

XXX At the moment, racoon can NOT negotiate the SA for VPN. Because
I don't clarify to define the relation between the values of ID
payloads and a pair of src/dst which cause the SA negotiation to
begin. Also racoon can NOT negotiate the socket based SA. Because
there is not any SP entry for socket in the kernel's SPD.

Mon Apr 24 13:08:42 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/mail/fetchmail: upgrade to 5.3.8.

Sun Apr 23 14:21:32 JST 2000 itojun@iijlab.net
* freebsd2/usr.bin/ftp: use RFC2732 URL format for Host: HTTP directive.

IPv6 numeric address).

2000-04-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_mroute.c (ip6_mdq): do not check scope
boundary for packets through a PIM register tunnel. Without this
change, an RP will not be able to forward packets received on a
register tunnel. However, this blindly relies on the routing
daemon's behavior. We'll eventually need more reliable fix.

2000-04-21 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/usr.bin/netstat/route.c (routename6): fill in the
sin6_socpe_id field of a local variable to support
<scope_addr>%<scope_id> extension.

Fri Apr 21 20:13:09 JST 2000 itojun@iijlab.net
* openbsd/sys/netinet{,6}/in{,6}_pcb.c: on in{,6}_pcbnotify, make sure

2000-04-21 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/netinet/ip_output.c (in_mrejoin): skipped PF_INET6
entries. This is a fix of a serious bug and should be applied if
you use IPv6 multicasting.

Thu Apr 20 21:32:02 JST 2000 itojun@iijlab.net
* sbin/route/route.c (freebsd[23], netbsd, bsdi[34]):
use scoped address notation when printing IPv6 link-local multicast
addresses.

2000-04-20 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/bgpd/ripng.c (rip_sockinit): do not bind ff02::9 on
the RIPng socket. Without this fix, bgpd can't accept unicasted
RIPng messages.
In response to a report from masahito_endo@ydc.co.jp

Thu Apr 20 18:22:26 JST 2000 itojun@iijlab.net

* sys/netinet{,6}/in{,6}_gif.c: do not attempt to transmit packet
if we are apparently making infinite loop.
* sys/netinet6/in6_gif.c: always fragment encapsulated IPv6 packet
to minimum IPv6 MTU. otherwise, inner layer (like IPv4 in
IPv4-in-IPv6) needs to retransmit to kick path MTU discovery in
the outer layer - too painful.

2000-03-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* bsdi4/sys/netinet/udp_usrreq.c (udp6_output): was copied from
netinet6/udp6_usrreq.c to separate UDP output routine from that of
IPv4, since KAME's UDP6 output had completely different logic from
original udp_output.

2000-03-23 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/in6_src.c (in6_pcbsetport): was moved from

IPv6 link-local gateway like
# route add add -inet6 3ffe:: fe80::1234%ed0 -prefixlen 16
instead of
# route add add -inet6 3ffe:: fe80:1::1234 -prefixlen 16
(where 1 embedded in the link-local address is the inteface index
of ed0).

2000-03-09 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* freebsd3/sys/netinet/tcp_input.c (tcp_input): did not try to
access to ip6_inputopts unless it's really an IPv6 packet.
In response to: a report from Noriaki Takamiya
<takamiya@po.ntts.co.jp>

Thu Mar 9 09:41:53 JST 2000 itojun@iijlab.net
* sys/netinet6/ah_core.c: except the first AH, treat AH checksum as
immutable if there are multiple AH present on a packet.
note that AH spec does not talk about this case very much, and use
of multiple AH is very rare.
(no interoperability between KAME code prior to this change, and
after this change)

__ivaliduser_sa...).

2000-02-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/ping6/ping6.c (main): added a new modifier "c" for the
-a option, which means target's IPv4 compatible and IPv4 mapped
addresses are required.

2000-02-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet/icmp6.h (NI_NODEADDR_FLAG_xxx): rearranged

Note: this version is not compatible with previous ones.

2000-02-28 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/kame/{advapitest, bgpd, pim6dd, pim6sd, rtsold, rrenumd,
traceroute6, rtadvd}: treated CMSG_SPACE() as a function, not a
constant macro, and avoided to put it in a definition of a static
array as a result.

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 execute 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>

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:

Wed Feb 24 08:49:50 JST 2000 sakane@ydc.co.jp
* kame/kame/racoon:
enbale to define DH group by a number of group.
old way to define like "modp768" is kept.

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.

Tue Feb 22 14:56:59 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* 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:
add library paths for "USA resident" case (link separate librsaref).

Mon Feb 21 15:53:56 JST 2000 itojun@iijlab.net
* netbsd/pkgsrc/www/apache: upgrade to 1.3.11 with IPv6 patch.

* bsdi4/sys/net/zlib.[ch]: were (blindly) copied from
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>
* bsdi4/sys/conf/files: removed ptr_xxx functions, which have been
obsoleted.

+ input/output filter for BGP4+ routes
+ configurable description about RIPng interfaces and BGP4+ peers
+ exportation of interface direct routes to IBGP peers
+ configurable logging level
+ collecting much more statistics
+ new configuration parser using lex and yacc

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:

* */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.

* 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.

Revised the format for scoped addresses by agreement with MSR.
Two big changes are included:
- The scope ID portion is now placed before the address
- The delimiter character is changed to '%'
So for example, we can specify a link-local address on the
interface ne0 like ne0%fe80::1234
The scopedaddr-format draft will soon be revised as well according
to this change.

matches longest against the destination address.
- if there is no other reasons to choose one, an address on the
outgoing I/F are preferred.

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

bring it in and try using it, to see any pros/cons we might have
in particular proposal (and other proposals).

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.

by Hiroshi Ura.

Tue Jan 18 00:46:09 JST 2000 itojun@iijlab.net
* kame/libinet6/getaddrinfo.c: don't filter out AFs that are not
supported by the kernel, when we do address resolution of FQDN.
the previous behavior was broken.

Mon Jan 17 13:47:13 JST 2000 itojun@iijlab.net

openbsd/ports/net/zebra: upgrade to 0.84a.

Mon Jan 17 2000 sakane@ydc.co.jp, itojun@kame.net
* racoon: tons of improvements into our IKE daemon.
- SA bundle is now handled correctly (both phase 1/2)
- will not SEGV even if last packet in phase 1/2 get resent
- KEYMAT generation will take care of long keys correctly
- phase 1/2 userfqdn support (ashley-laurent hack)
- don't attach DH group type for well-known groups
- key length handling is fixed
- phase 1 base mode
- byte lifetime bug fix (but introduced new bug so still buggy)
- parser fixes (issue with DH group setting)
- fix variable-length spi support (don't hardcode it to 32bit)
- ipcomp negotiation fix
* kernel ipsec: fix SA reference counting. now dangling SAs will be
cleaned up correctly. (removes incorrect fix on Jan 8 2000)

Mon Jan 17 03:36:44 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/sys/netkey/keysock.c: this file was removed. Now
freebsd3 uses shared one, kame/sys/netkey/keysock.c

NOTICE: If you use freebsd3 via cvsup/anoncvs, you must clean
your source tree and relink shared sources.
% cd kame; make TARGET=freebsd3 clean prepare

Mon Jan 17 02:25:54 JST 2000 itojun@iijlab.net
* {netbsd,bsdi3,freebsd2}/netstat: try to share souce code across OS
platforms as much as possible. we are able to share ipsec.c without
too much troubles. will try to do it for other platforms, and other
portions (like inet6.c).

Sun Jan 16 23:30:16 JST 2000 itojun@iijlab.net
* kame/sys/net{inet6,key}: cleanup ipsec logging. all logs will be
generated to syslog, with proper priority (for example, sequence
number cycle will be logged with LOG_WARNING). you can
suppress/enable logs by setting net.inet.ipsec.debug (or
net.inet6.ipsec6.debug). even if you supress logs, you can check
"netstat -sn" to understand what was happend to ipsec stack.

Sat Jan 15 03:56:50 JST 2000 itojun@iijlab.net
* kame/sys/netinet6/ipcomp_core.c: change default deflate window size
for inbound to default (2^15). without this change we can't
interoperate with some of IPcomp implementations.
see changelog entry on Nov 5 1999.

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.

Fri Jan 14 13:55:19 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>

FreeBSD-current.

Fri Jan 14 12:15:27 JST 2000 itojun@iijlab.net
* kame/libinet6/rcmd.c: avoid passing dangling pointer to **ahost.
we copy the value (ai_canonname, or hp->h_name) to static buffer
to keep semantics of rcmd() - requires no free() to the caller.
From: Hideaki YOSHIFUJI <yoshfuji@ecei.tohoku.ac.jp>

Fri Jan 14 02:16:16 JST 2000 itojun@itojun.org
* kame/libpcap/inet.c: improve warning message when libpcap fails to
get IPv4 address on the interface it runs on.

Wed Jan 12 17:21:40 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/ruby: Upgrade to 1.4.3 and sync with
FreeBSD-cuurent. No extra IPv6 patch is necessary anymore.

Wed Jan 12 15:40:05 JST 2000 itojun@iijlab.net
* {bsdi3,netbsd,freebsd2}/usr.sbin/inetd: allow multiple IPsec policy
string specifier (separated by semicolon). to be integrated into
other operating systems as well.

Wed Jan 12 05:13:33 2000 SUMIKAWA Munechika <sumikawa@ebina.hitachi.co.jp>
* freebsd3/ports/mrt, netbsd/pkgsrc/net/mrt: Upgrade to 2.1.2a.

2000-01-10 JINMEI, Tatuya <jinmei@isl.rdc.toshiba.co.jp>
* kame/sys/netinet6/ip6_output.c (ip6_pcbopt): made the
IPV6_NEXTHOP socket option removal by specifying the option
with 0 length according to the following mail:
Message-ID: <Roam.SIMC.2.0.6.947118462.12265.nordmark@jurassic>
From: Erik Nordmark <Erik.Nordmark@eng.sun.com>

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@ydc.co.jp
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.

Sat Jan 8 23:53:23 JST 2000 sakane@ydc.co.jp
* kame/sys/netkey/key.c:
- fix kenrel crash when flushing SAD.
- for stability, increment refcnt of SA when key_getsavbyspi() called.

- fix errno at key_update().

Sat Jan 8 04:40:33 JST 2000 itojun@iijlab.net
* kame/sys/netinet/{frag6,ip6_input,nd6_nbr}.c:
use arc4random() on openbsd. it should give better random value
for initializing sequence numbers.
From: deraadt@openbsd.org

Sat Jan 8 03:20:05 JST 2000 itojun@iijlab.net
* /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.

Sat Jan 8 00:37:28 2000 Shin'ichi Fujisawa <fujisawa@kame.net>
* kame/sys/netinet6/natpt*.[ch]: NAT-PT translator.
* kame/kame/{natptconfig,natptd,natptlog}: translator configulation
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>
* freebsd3/ports/openssh: upgrade to current source of OpenBSD,
which support IPv6 in default. Any additional patches does not
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
* sys/netinet6/ip6_input.c: add missing case for net.inet6.ip6.rr_prune
for openbsd and netbsd.
* netbsd/pkgsrc/net/zebra, freebsd[23]/ports/zebra: upgrade to 0.83a.

Thu Jan 6 01:40:50 JST 2000 itojun@iijlab.net
* sys/netinet6/icmp6.c: avoid panic on getsockopt(ICMPV6_FILTER).
From: shigeya@foretune.co.jp
* {openbsd,bsdi4}/sys/netinet6/raw_ipv6.c: clarify rip6_ctloutput().

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
* kame/sys/netkey:
don't check sequence number at key_update() even if SA initiator.
don't change sequence number passed from userland at key_getspi()
instead of the value of sequence number.
They can be re-enable to define IPSEC_DOSEQCHECK.

Sun Jan 2 22:59:45 JST 2000 itojun@iijlab.net
