itojun 23c246780c consistent logging for icmp6 redirects 
XXX should make logs 1-liner so that duplicated logs can be compressed
by syslog(8)?
 1999-10-01 10:16:16 +00:00
itojun 97999826c8 sanity check against truncated extension headers. 1999-10-01 10:15:16 +00:00
is 1eb4d34bba Add missing "case IFT_ARCNET". 1999-09-26 20:08:15 +00:00
is 3a43ac11b5 Don't even pretend we can create a nonglobal EUI64 out of an ARCNET link 
level address. Instead, create the link-local address directly.
 1999-09-26 20:04:08 +00:00
is 1f417b8ca9 invert u bit to convert EUI64 to RFC2373 interface ID for ARCnet 1999-09-25 22:29:21 +00:00
itojun 62c568fac4 tiny fix to ARCnet IPv6 support. 
- in in6_ifattach_getifid(), we can grab interface id source iff the source
  is universally (worldwide) unique.  ARCnet hardware address is of 8bit and
  does not satisfy the condition.
  (in6_ifattach_getifid() is for getting interface id usable for pseudo
  interfaces like gif*)
- xx_to_eui64() should return EUI64 format, not IPv6 interface id format.
  this may seem awkward so I wish to clean these things up.
- in nd6.c, change if clause into case clause to allow future addition
  of IFT_xxx easier.

is 6a793d8a47 Zeroth version of IPv6 support for ARCnet. Correct MTU handling still needs 
to be done.

itojun b3d9b0130c eliminate unnecessary splnet(). 1999-09-17 12:26:04 +00:00
itojun 6b9bfc0691 - Call in{,6}_pcbdetach if ipsec initialization is failed during PRU_ATTACH. 
This situation happens on severe memory shortage.  We may need more
  improvements here and there.
- Grab IEEE802 address from IFT_ETHER card, even if the card is
  inserted after bootup time.  Is there any other card that can be
  inserted afterwards?  pcmcia fddi card? :-P
- RFC2373 u bit handling suggests that we SHOULD NOT copy interface id from
  ethernet card to pseudo interface, when ethernet card has IEEE802/EUI64
  with u bit != 0 (this means that IEEE802/EUI64 is not universally unique).
  Do not use such address as, for example, interface id for gif interface.
  (I have such an ethernet card myself)
  This may change interface id for your gif interface.  be careful upgrading
  rc files.

itojun 45538437d9 - invert u bit on interface id for pseudo interfaces, as suggested in RFC2373. 
- do not perform IPv6 initialization for faith* interface, as they become
  mistakingly IFF_UP.  we are wondering if we should nuke in6_ifattach_p2p().

itojun a9b7fe4621 return with doing nothing from xx_ctlinput(), when sa->sa_family 
is not the expected one.

I see PRC_REDIRECT_HOST with sa->sa_family == AF_UNIX coming to
{tcp,udp}_ctlinput() when I use dhclient, and I feel like adding
more sanity checks, without logging - if we log it it is too noisy.

explorer ed3b6d5791 Fix a problem where tcp_slowtimo was called twice, once for ipv4 tcp and 
once for ipv6.  This patch makes the ipv6 case pass NULLs in for fast
and slow timeouts iff defined(INET) and passes in the right function
if !defined(INET).

kleink dd24133620 Take a stab at namespace protection. For now, only the obvious problems are 
addressed, the culprit being the lack of a namespace definition for an IPv6-
extended <netinet/in.h> in XNS5.2 D2.0; I'll try to work something out and
submit it to the review WG.
