itojun 5fc1c3b058 do not differentiate manually configured address from autoconfigured ones
wrt prefix management;
- always earn a reference to the prefix when an address is configured
 (by ioctl).
- always delete the prefix when an address that has the last referene
  is manually removed.

The change should solve the problem raised in KAME-snap 6989.

behavior changes:
- two iocts used by ndp(8) are now obsolete (backward compat provided).
  use sysctl path instead.
- lo0 does not get ::1 automatically.  it will get ::1 when lo0 comes up.

onoe e83458422f First Prototype implementation of network interface part for IEEE1394 (if_fw).
Current status:
	Only OHCI chip is supported (fwohci).
	ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
	sometimes works but not stable.
Not implemented yet:
	IRM (Isochronous Resource Manager) functionality.
	Link layer fragmentation.
	Topology map.
More to do:
	clean ups
	MCAP
	charactor device part
	dhcp

There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.

itojun 6574aa66e8 inhibit error code from rtinit(). this happens when we try to assign
multiple addresses from same prefix, onto single interface.  PR 10427.


more info:
- 4.4BSD did not check return code from in_ifinit() at all.
  4.4BSD does not support multiple address from same prefix.
- past KAME change passed in{,6}_ifinit() to upwards, toward ifconfig(8).
  the behavior is filed as PR 10427.
- the commit inhibits EEXIST from rtinit(), hence partially recovers old
  4.4BSD behavior.
- the right thing to happen is to properly support multiple address assignment
  from the same prefix.  KAME tree has more extensive change, however, it needs
  much more time to get stabilized (rtentry refcnt change can cause serious
  issue, we really need to bake it before bring it to netbsd)
2000-08-02 15:03:02 +00:00
itojun 20964b0c23 fatal bug fix from kame (rtentry refcnt goes negative if we play with IPv6
address/routing table too much).

in6_ifloop_request()
  not to request rtrequest to return an rtentry except for the ADD
  operation, in order to avoid misdecreasing the refcnt (which might
  cause leak of rtentry)

itojun ecb5f2e56a revisit in6_ifattach().
- be persistent on initializing interfaces, even if there's manually-
  assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel.  grab mac addr from existing cards
  (this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!

call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.

(the change is in sync with kame tree).

2000-03-24 04:09:04 +00:00
thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

itojun d926d6fa47 #if 0'ed undo code for interface address addition failure.
it was a bit too strong, and forbids multiple addresses from
same prefix to be assigned.

now the behavior is the same as previous - memory leak on interface address
addition failure.
